BUSINESS REVIEW 
 
KEY OPERATIONAL PROGRESS 
 
Improving operational performance and delivering benefits for customers and the 
environment remain top priorities for United Utilities (UU). Alongside this, we 
are on track to outperform our regulatory contract. We have made significant 
progress since the start of the 2010-15 regulatory period, as outlined below: 
 
* Significant improvements in customer service - We have significantly improved 
the customer experience over the last three years, as demonstrated through 
Ofwat's customer service measure the service incentive mechanism (SIM). We 
achieved the best improvement in the industry on Ofwat's combined SIM score in 
2011/12, moving up five places to 16th position out of the 21 water companies. 
We have built on this and have improved further in 2012/13, although our 
qualitative SIM score for the last quarter of the year saw us slip back against 
the trend achieved in the first three quarters. We ended the 2012/13 year in 
14th place in the sector on this measure, up two places on the previous year. 
This represents a mid-ranking position among the ten water and wastewater 
companies. Encouragingly, we have recently received our qualitative SIM score 
for the first quarter of 2013/14 and we achieved 10th position out of the 21 
water companies. Customer complaints to the Consumer Council for Water (CCW) 
have continued to fall with zero complaints warranting investigation by the CCW 
in 2012/13, the first time we have achieved this. 
 
* Strong operational performance - We performed well across a broad front, as 
measured in Ofwat's latest (2011/12) key performance indicators report. Of the 
fifteen assessments, UU was rated `Green' for eleven and `Amber' on four, with 
no areas assessed as `Red' on the traffic light reporting matrix. This balance 
of ratings is above the average performance level, in respect of the ten water 
and sewerage companies. This performance has helped provide benefits for 
customers, for example in terms of better customer service and very high levels 
of reliability and availability of water supply and wastewater services, 
alongside a range of environmental benefits. 
 
* Effective capital delivery drives customer and environmental benefits - We 
continue to drive more effective and efficient delivery of our capital 
programme. This is reflected in a significant improvement in our Time: Cost: 
Quality index (TCQi) score from around 50% in 2010/11 to approximately 90% in 
2012/13, meeting our target two years ahead of schedule. This has helped us 
accelerate our capital investment programme and has helped us deliver all of 
our capital investment Environment Agency commitments this year. We have met 
our water and wastewater asset serviceability standards and have confidence 
that our performance in respect of meeting our 2010-15 regulatory commitments 
will be much improved, compared with the 2005-10 period. Our aim is to deliver 
our commitments on time and to specification in order to avoid or minimise any 
revenue penalties in the 2015-20 period. We have now invested just over GBP2 
billion across the first three years of this regulatory period, as we have 
sought to deliver a smoother investment profile to support efficient delivery 
of outputs and reduce risk. 
 
* Outperformed regulatory leakage target - We have met or outperformed our 
regulatory leakage target for the seventh consecutive year. This reflects 
strong year round operational focus, coupled with the benefits from our 
reinvestment initiatives, helping to support a robust water supply and demand 
position in our region and provide high levels of reliability for our 
customers. 
 
* Regulatory outperformance on track - We have set clear targets for the 
2010-15 period and remain on track or ahead of schedule in delivering these 
targets. We expect to reinvest around GBP200 million of capex outperformance, 
over 2010-15, for the benefit of our customers and the environment. 
 
* Corporate responsibility - We have held a `World Class' rating in the Dow 
Jones Sustainability Index for five consecutive years, attaining our highest 
ever score in the most recent assessment. We also have the highest `Platinum 
Big Tick' ranking in Business in the Community's Corporate Responsibility 
Index. In addition, we hold membership of the FTSE 350 Carbon Disclosure 
Leadership Index and are the top UK utility company in this index by some 
distance. We are one of only four FTSE 100 companies to hold all three awards. 
 
* Extending our presence in the retail water market for business customers - We 
have been building our capability to help ensure we are in a strong position as 
the competitive business retail market evolves and are very active in this 
expanding market. We appointed Sue Amies-King from Aviva, in the newly created 
role of Retail Director in June 2012, and subsequently recruited Tony McHardy 
from Business Stream as Sales Director. We secured a Scottish water supply 
licence in 2012 and have won several business customers in Scotland, with a 
significant pipeline of opportunities. We are also delivering a range of 
value-added services. 
 
FINANCIAL OVERVIEW 
 
The group has delivered another good set of financial results for the year 
ended 31 March 2013. Revenue was up by GBP71 million to GBP1,636 million, 
principally as a result of the impact of the regulated price increase for 2012/ 
13 of 5.8% nominal (0.6% real price increase plus 5.2% RPI inflation) partially 
offset by reduced volumes and the ongoing impact of customers switching to 
meters. 
 
Underlying operating profit increased by GBP13 million to GBP607 million, despite 
an expected increase in depreciation, as we kept cost increases below price 
inflation. 
 
Total regulatory capital investment for the year, including GBP161 million of 
infrastructure renewals expenditure, was GBP787 million, representing an increase 
of 16% compared with last year, reflecting continued progress on the capital 
investment programme. 
 
Underlying profit before taxation was up 8%, at GBP354 million. This was a result 
of higher underlying operating profit, coupled with a lower underlying net 
finance expense mainly due to lower RPI inflation. 
 
Underlying profit after taxation was 11% higher than last year, at GBP266 
million, reflecting the reduction in the mainstream UK corporation taxation 
rate. Reported profit after taxation benefited from a GBP53 million deferred 
taxation credit (GBP105 million credit in 2011/12), which follows the UK 
Government's changes to reduce the mainstream corporation taxation rate. 
 
The group has a robust capital structure and gearing (measured as group net 
debt to regulatory capital value) as at 31 March 2013 was 60%, in the middle of 
Ofwat's assumed range of 55% to 65%, supporting a solid investment grade credit 
rating. United Utilities Water PLC (UUW) has a long-term credit rating of A3 
from Moody's Investors Service with a stable outlook. 
 
The group benefits from headroom to cover its projected financing needs into 
2015, following the recent raising of a GBP100 million index-linked loan at our 
lowest ever annual interest rate of 0.5% real. This provides good flexibility 
in terms of when and how further debt finance is raised to help fund the 
regulated capital investment programme. Reflecting this robust financing 
position, UU has completed early all previously agreed pension deficit repair 
payments covering the 2010-15 regulatory period. 
 
In line with its policy, the board has proposed a final dividend of 22.88 pence 
per ordinary share, an increase of 7.2%, taking the total dividend for 2012/13 
to 34.32 pence. 
 
OUTLOOK 
 
Our sustained focus on operational performance, combined with continued 
substantial investment in our assets, is delivering benefits for our customers 
and the environment. We have improved further on Ofwat's service incentive 
mechanism and believe there is plenty of scope to deliver more for our 
customers. We have made good progress on our capital expenditure programme and 
our disciplined investment approach provides us with confidence that we will 
deliver a good performance in respect of meeting our regulatory commitments 
across the 2010-15 period. We remain on track or ahead of schedule in meeting 
our five-year regulatory outperformance targets. We intend to continue with our 
dividend policy of targeting 2% per annum growth above the rate of RPI 
inflation through to at least 2015, underpinned by a robust capital structure. 
We will continue to positively engage with Government and regulators to support 
the progressive evolution of the water industry and are actively involving our 
customers to help shape our business plan for the forthcoming price review. 
 
OPERATIONAL PERFORMANCE 
 
Supporting our drive to improve operational performance, last year we put in 
place a revised management structure with a strong focus on accountability and 
delivery. We moved from our previous functional structure, to an organisational 
structure where managers are responsible for end-to-end delivery of capital 
projects and operational performance within their respective regions, providing 
a more integrated approach. We have refined our organisational structure 
further in preparation for a more competitive environment and to align with the 
separated price controls that will apply at the 2014 price review. With effect 
from April 2013, we have revised our structure and activities around three 
business areas: Wholesale; Domestic Retail; and Business Retail. 
 
We continue to make good progress towards our objective of becoming a leading 
North West service provider and one of the best UK water and wastewater 
companies. We are pleased to have been consistently ranked third out of ten 
leading organisations in the North West, through an independent brand tracker 
survey which is undertaken quarterly. We are behind Marks & Spencer and John 
Lewis, but ahead of seven other major organisations covering utilities, 
telecoms, media and banking services. We have made further operational 
improvements during the year and have improved our performance relative to our 
water sector peers. 
 
United Utilities aims to deliver long-term shareholder value by providing: 
 
* The best service to customers 
 
* At the lowest sustainable cost 
 
* In a responsible manner 
 
 
Best service to customers 
 
We believe in delivering a fair deal for our customers and have continued to 
invest in our people, assets, systems and processes to improve the service our 
customers can expect of us. In addition, we expect to reinvest around GBP200 
million of capex outperformance over the 2010-15 period for the benefit of our 
customers and the environment. 
 
Robust water supply and reliability - We have implemented active pressure 
management in our water network to reduce bursts and leakage, helping us to 
meet or outperform our leakage target. Should we have a burst, the additional 
investment completed during the year in strategic mains refurbishment and 
connectivity has improved the capability of our water network to maintain 
supply. Whilst the North West did not experience the hose-pipe bans seen 
elsewhere in the country last spring, rainfall across our region was much lower 
than expected. We were able to benefit from our investment in an integrated 
regional water network to keep customers supplied throughout the dry period. 
Overall, our customers continue to benefit from our robust water supply and 
demand balance and high levels of water supply reliability. We have again 
achieved a high level of water quality, with mean zonal compliance continuing 
to be over 99.9%. 
 
Investing to mitigate sewer flooding - The latter half of 2012 was 
characterised by a large number of exceptionally high rainfall events and this 
proved to be a testing time for our wastewater assets. We were disappointed to 
miss our Ofwat target in respect of the number of sewer flooding incidents, but 
have continued to invest heavily in schemes designed to mitigate the risk of 
flooding of our customers' homes. Our wastewater network will continue to 
benefit from significant investment going forward as we adapt to weather 
patterns likely to result from climate change. 
 
Improving customer service performance - We have continued to develop our 
systems and processes to deliver the experience our customers seek when they 
need to contact us, including multi-channel contact centre technology. This has 
helped us deliver further improvements in our performance on Ofwat's service 
incentive mechanism (SIM), reflecting our continuing strong focus on dealing 
with customer enquiries. The number of customer complaints made to the Consumer 
Council for Water (CCW) in 2012/13 has reduced by a further 11%, compared with 
2011/12. We are pleased to report that the total number of escalated complaints 
assessed by the CCW was zero in the 2012/13 financial year, which is the first 
time we have achieved this. This has helped us improve our SIM performance 
further, as detailed in the KPIs section below, although our qualitative SIM 
score for the last quarter of 2012/13 saw us slip back against the trend 
achieved in the first three quarters. We ended the year in 14th place in the 
sector on this measure, up two places on the previous year. Encouragingly, we 
have recently received our qualitative SIM score for the first quarter of 2013/ 
14 and we achieved 10th position out of the 21 water companies. 
 
Asset serviceability - We have a range of actions to help support the 
serviceability of our assets. We are improving the robustness of our water 
treatment processes, refurbishing service reservoir assets, continuing with our 
comprehensive mains cleaning programme and are optimising water treatment to 
reduce discoloured water events. To help reduce sewer flooding, the actions 
include incident based targeting to focus on areas more likely to experience 
flooding, effective intervention in cleaning and rehabilitation or 
refurbishment of sewers and advising customers about items not suitable for 
sewer disposal. Our programme also includes defect identification through CCTV 
sewer surveys, along with continual improvement of wastewater reporting systems 
to enable real time operational information to be made visible at all 
management levels and promote early intervention. Our comprehensive range of 
actions has helped us meet our water and wastewater serviceability standards, 
as detailed in the KPIs section below. 
 
Retail competition for business customers - We have been building our 
capability to help ensure we are in a strong position to compete as the 
business market for retail customers evolves. We secured a water supply licence 
in 2012 to compete in Scotland and have built a team with a deep retail 
background in the utility and commercial sectors. Although the financial 
benefits from retail activities are relatively small at this stage, the market 
will evolve and business customers are looking for services over and above 
meter reading and billing. We are delivering a range of value-added services, 
such as on-site engineering solutions and water efficiency advice. We are 
pleased to have extended our presence and have now won several business 
customers outside of our region. We also have a significant pipeline of 
opportunities, a number of which are multi-site customers. 
 
Improving customer service remains a significant area of continued management 
focus and we see plenty of opportunity to deliver further benefits for our 
customers. 
 
Key performance indicators: 
 
* Serviceability - Long-term stewardship of assets is critical and Ofwat 
measures this through its serviceability assessment (Ofwat defines 
serviceability as the capability of a system of assets to deliver a reference 
level of service to customers and to the environment now and in the future). 
Our range of actions has helped us return our wastewater infrastructure assets 
to a `stable' rating, from a `marginal' rating, and we are now meeting our 
serviceability standards. We are currently assessed as `improving' for our 
wastewater non-infrastructure assets and `stable' for our water infrastructure, 
water non-infrastructure and wastewater infrastructure assets. The aim is to 
continue to hold at least a `stable' rating for all four asset classes, which 
is aligned with Ofwat's target. 
 
* Service incentive mechanism (SIM) - UU made significant progress on Ofwat's 
combined SIM assessment for 2011/12, moving up five places to 16th of the 21 
water companies, compared with 2010/11. This represented the largest overall 
SIM score improvement in the industry. Further progress has been made in 2012/ 
13, with a quantitative score of 179 points, representing a further 34% 
improvement compared with 2011/12. On the qualitative measure, UU has improved 
its 2012/13 average score by 0.25 points to 4.43 points, moving up two further 
places to 14th position, which represents 6th place among the ten water and 
sewerage companies. Our continued progress is encouraging, as we aim to move to 
the first quartile in the medium-term. 
 
Lowest sustainable cost 
 
We are continuing to implement a wide range of initiatives to help optimise our 
performance and deliver sustainable efficiencies. 
 
Materials - Our asset optimisation programme continues to provide the benefits 
of increased and more effective use of operational site management to optimise 
power and chemical use and the development of more combined heat and power 
assets to generate renewable energy. 
 
Proactive network management - We are implementing a more proactive approach to 
asset and network management, with the aim of improving our modelling and 
forecasting to enable us to address more asset and network problems before they 
affect customers, thereby reducing the level of reactive work and improving 
efficiency. 
 
Energy costs - We have substantially locked in the cost of our power 
requirements through to 2014/15, via hedging, securing outperformance. Although 
power unit costs for 2013-15 have been secured at higher levels than those for 
2011/12, this still delivers additional outperformance versus the regulatory 
contract. 
 
Debt collection - We are continuing to enhance our proactive approach to debt 
collection and are implementing a detailed action plan. The North West faces a 
particularly tough economic environment, with unemployment having increased at 
a faster rate than any other UK region in 2011/12, particularly in the second 
half, resulting in an adverse impact on customers' ability to pay this year. 
Although North West unemployment improved in 2012/13, its remains higher than 
the position at March 2011 and is still above the national average. We 
recognise the financial difficulties facing many of our customers and provide a 
range of options to help our customers who are struggling to pay their bills, 
including our charitable trust, and we have helped many customers back onto 
manageable payment plans. Despite the tough economic climate, our range of 
actions have helped us to again deliver a good performance and we have 
sustained bad debts at 2.2% of regulated revenue for 2012/13, consistent with 
last year. 
 
Pensions - UU placed its pension provision on a more sustainable footing in 
2010 and has subsequently taken additional steps to de-risk the pension scheme 
further, with the group now benefiting from a small pension surplus. Further 
details on the group's pension provision are provided in the pensions section. 
 
Capital delivery - The business is strongly focused on delivering its 
commitments efficiently and on time and has a robust commercial capital 
delivery framework in place for the 2010-15 period. We have improved our 
internal Time: Cost: Quality index (TCQi) score from around 50% in 2010/11 to 
approximately 90% in 2012/13. This means we have met our target two years ahead 
of schedule and we are firmly focused on sustaining this substantial 
improvement. This helped us accelerate our capital programme to help optimise 
capital delivery and reduce risk towards the end of the regulatory period. 
Regulatory capital investment in 2012/13, including GBP161 million of 
infrastructure renewals expenditure, was GBP787 million, an increase of 16% 
compared with last year. This increase of over GBP100 million means that our 
cumulative investment across the first three years of the 2010-15 regulatory 
period is now just over GBP2 billion, reflecting a smoother and more effective 
investment profile than the previous five-year cycle. We remain on track to 
deliver the five-year programme within the regulatory allowance of around GBP3.5 
billion and we are reinvesting any capex outperformance to deliver further 
customer benefits. We expect to deliver around GBP800 million of capital 
investment in 2013/14. 
 
Regulatory commitments - Delivering our regulatory commitments is key, not only 
in terms of service to customers and the environmental impact, but also in 
respect of shareholder value. UU received a shortfalling revenue penalty of 
over GBP80 million at the last price review in 2009. Shortfalling is effectively 
where a company fails to deliver agreed requirements on time or to 
specification. We are strongly focused on meeting our regulatory commitments, 
as we aim to avoid, or at least minimise, any shortfalling revenue penalties at 
the 2014 price review. We are making good progress and we have delivered all of 
our capital investment Environment Agency commitments this year. This 
represents a much improved performance, so far, compared with the 2005-10 
regulatory period, and we will continue to treat this as a priority area. 
 
Private sewers - The transfer of private sewers around 18 months ago has gone 
well and is now embedded within our `business as usual' activities. The volume 
of work and the level of expenditure continues to be a little below our 
expectations. The mix of work continues to relate more to enhancement capex 
than opex, compared with what we initially expected at the onset. Our operating 
model has evolved to reflect the revised work scope and volumes. In addition to 
routine maintenance activity, we are enhancing the quality of the assets where 
appropriate. This will bring the private sewer infrastructure more in line with 
our asset standards and will reduce the risk of future problems for our 
customers. In 2012/13, we spent GBP8 million on opex, GBP11 million on 
infrastructure renewals expenditure and GBP14 million in relation to enhancement 
capex. Although spend rates remain a little lower than we anticipated, we are 
still only 18 months into the transfer so we are not changing our 2011-15 total 
cost estimate of GBP160 million (GBP40 million opex, GBP60 million infrastructure 
renewals expenditure and GBP60 million enhancement capex) at this stage. This 
lower rate of spend and the mix of work continues to be positive for both our 
customers and our investors. 
 
Key performance indicators: 
 
* Financing outperformance - UU has secured over GBP300 million of financing 
outperformance across the 2010-15 period, when compared with Ofwat's allowed 
cost of debt of 3.6% real, based on an average RPI inflation rate of 2.5% per 
annum. We expect to reinvest around GBP40 million of our financing outperformance 
in unfunded private sewers costs. 
 
* Operating expenditure outperformance - The business is targeting total 
operating expenditure outperformance over the 2010-15 period of at least GBP50 
million, or approximately 2%, compared with the regulatory allowance. This is 
in addition to the base operating expenditure efficiency targets set by Ofwat, 
which equate to a total of approximately GBP150 million over the five years. We 
have now delivered cumulative operating expenditure outperformance of around GBP 
50 million in the first three years of the regulatory period and are ahead of 
schedule. 
 
* Capital expenditure outperformance - UU is continuing to deliver significant 
efficiencies in the area of capital expenditure and expects to meet Ofwat's 
allowance after adjusting, through the regulatory methodology, for the impact 
of lower construction output prices. We expect to reinvest around GBP200 million 
of capital expenditure outperformance for the benefit of our customers and the 
environment. 
 
Responsible manner 
 
Acting responsibly is fundamental to the manner in which we undertake our 
business and the group has for many years included corporate responsibility 
factors as a strategic decision in its decision making. 
 
Leakage - We were pleased to beat our regulatory leakage target in 2012/13. 
This reflects our year round operational focus and the implementation of range 
of initiatives, such as active pressure management. Our leakage performance, 
alongside the network resilience improvements we are making, are helping us to 
maintain a robust water supply and demand balance and deliver high levels of 
reliability for our customers. 
 
Improving rivers and bathing water quality - We have a range of capital 
projects which are delivering significant customer and environmental benefits. 
We are undertaking a GBP100 million+ project in Preston, which is designed to 
improve river and bathing quality. The project involves building a 3.5 
kilometre storm water storage tunnel and the construction of shafts to divert 
storm water flows, which will be retained in the new storage tunnel. It will 
reduce the number of spills to the River Ribble from combined sewers and should 
deliver significant improvements to the Flyde Coast bathing waters and the 
Ribble Estuary. This is one our largest projects in the 2010-15 period and is 
now nearing completion. Our Liverpool wastewater treatment works expansion 
project, at around GBP200 million, is our largest capital programme in this 
regulatory cycle. The project will enhance the capacity of the works so it can 
treat up to 11,000 litres of wastewater per second. The project is progressing 
well and the higher standards of treatment will continue the rejuvenation of 
the River Mersey and improve bathing waters across the river on the Wirral. It 
also provides a significant contribution to the local economy. The extended 
works are expected to come online in early 2016. 
 
Reducing our carbon footprint - We are committed to reducing our carbon 
footprint and increasing our generation of renewable energy. Our carbon 
footprint for 2012/13 was 524,264 tonnes of carbon dioxide equivalent, a minor 
increase of 0.4% compared with last year. This was as a result of an increase 
in the amount of electricity purchased as we undertook additional pumping 
activity. Not only did we experience one of the wettest years on record, 
resulting in significantly more wastewater in our sewers and treatment works, 
the year began and ended with a prolonged dry spell, so we needed to pump 
additional volumes of water around our integrated network. We were pleased to 
retain the Certified Emissions Measurement and Reduction Scheme certification 
for our carbon accounting methodology. We remain on track to meet our target of 
a 21% reduction in carbon emissions by 2015 (measured from a 2005/06 baseline). 
UU has consistently generated around 100 GWh of renewable electricity annually 
for the past four years, principally from sludge processing. By 2014, we expect 
to have finished commissioning an innovative GBP100 million+ recycling and energy 
plant at one our largest wastewater treatment works at Davyhulme, near 
Manchester. By treating sludge that is left over at the end of the wastewater 
treatment process, we can generate enough electricity from biogas to power the 
Davyhulme site. Sludge is also converted into a valuable agricultural 
fertiliser. 
 
Environmental performance - This is a high priority for UU and we were pleased 
to report the lowest number of major pollution incidents of the ten water and 
wastewater companies, per kilometre of pipe, for 2011/12 (the latest available 
assessment). Our operational and environmental focus is delivering results and 
we were pleased to achieve our best performance for many years in the 
Environment Agency's performance metrics, where we have been rated as an `above 
average performer', as detailed in the KPIs section below. 
 
Employees - A committed, capable and motivated workforce is central to 
delivering our vision and we remain strongly focused on high levels of employee 
development and engagement. We continue to be successful in attracting and 
retaining people and we were pleased to also extend our apprentice programme 
during the last year. We currently employ over 80 apprentices and plan to 
recruit up to a further 40 apprentices each year through to 2015. Alongside 
this, we are continuing to expand our graduate recruitment scheme, with plans 
to add more than 20 graduates in 2013/14. This is in addition to over 35 
graduates we currently employ. As part of our health and safety improvement 
programme, we implemented a number of initiatives throughout the year and 
launched a set of behavioural standards at our main office sites, called the 
`Safety Six'. Health and safety will continue to be a significant area of focus 
for the company, as we strive for continuous improvement. 
 
Communities - We continue to support community partnerships, which help in 
meeting our company objectives. For example, our partnership with UTV Media 
takes an online programme into schools to enable them to create a radio advert 
(part of the national curriculum) linked to one of our key campaigns, such as 
water efficiency or reservoir safety. With an emphasis on promoting the adverts 
through social media, this provides an innovative way for our key messages to 
reach our customers. Education is an integral part of our community approach 
and our new outreach education partnership started this year and has already 
reached 139 schools and 4,754 children. Where we cause disruption as part of 
our major capital works, we invite local community groups to apply for small 
scale grants to support their work. Last year we contributed to 116 groups in 
10 locations across the North West. We also contributed approximately GBP2 
million supporting local communities providing debt advisory services and 
undertook over 26,000 hours of employee volunteering. 
 
Leading credentials - Our environmental and sustainability performance across a 
broad front has received external recognition. UU continues to be rated `World 
Class' in the Dow Jones Sustainability Index and has retained the highest 
ranking, `Platinum Big Tick', in Business in the Community's Corporate 
Responsibility Index. In addition, UU holds membership of the FTSE 350 Carbon 
Disclosure Leadership Index. UU is one of only four FTSE 100 companies to hold 
all three awards. 
 
Key performance indicators: 
 
* Leakage - UU met its economic level of leakage rolling target for the seventh 
consecutive year in 2012/13, with a performance of 457 megalitres per day 
versus the regulatory target of 464 megalitres per day. The aim is to meet our 
regulatory leakage target each year. 
 
* Environmental performance - On the Environment Agency's latest assessment, 
which covers a broad range of operational metrics, UU has been rated as an 
`above average performer'. UU has three areas highlighted as `Green', four as 
`Amber', and, importantly, no areas highlighted as `Red' on the traffic light 
reporting matrix. This would indicate 3rd position among the ten water and 
sewerage companies. Although the EA has revised its performance measure, UU was 
in 7th position on the EA's composite assessment for the previous year, so this 
represents good progress against the medium-term goal of being a first quartile 
company on a consistent basis. 
 
* Corporate responsibility - UU has a strong focus on corporate responsibility 
and is the only UK water company to have a `World Class' rating as measured by 
the Dow Jones Sustainability Index. The group aims to retain this `World Class' 
rating each year. 
 
POLITICAL AND REGULATORY DEVELOPMENTS 
 
UU is actively involved in political and regulatory developments that relate to 
the UK water sector and has a proactive programme to engage with all key 
stakeholders. The retention of investor confidence and customer affordability 
remain key areas of importance. 
 
Water Bill 
 
We have been actively engaging with the UK Government on its reform agenda. The 
UK Government published a draft Water Bill in July 2012 and we provided 
evidence to the Efra Select Committee, as we strive to achieve the optimal 
outcome for all of our stakeholders. The reform agenda for our sector is also 
providing new opportunities for us. In addition to the adoption of private 
sewers and the expanding retail water market for business customers, we are 
currently exploring opportunities in areas such as water and sludge trading 
with our regulators. A Water Bill was announced in the Queen's Speech on 8 May 
2013 and we now await the UK Government's publication of the Bill with 
interest. 
 
2014 price review 
 
We continue to play an active role and engage positively in regulatory reform. 
Following a period of constructive dialogue with Ofwat, we were pleased to 
accept the revised licence modification proposals which were published by the 
regulator on 21 December 2012. These revised licence proposals focus on the 
changes required to facilitate the 2014 price review and we are now working 
closely with the regulator to help shape the forthcoming price review. Ofwat 
published its 2014 price review methodology consultation in January 2013 and we 
submitted our response to Ofwat in March. We await Ofwat's methodology document 
later in the year. We are actively engaging our customers and other 
stakeholders to help us formulate our business plan for the 2015-20 period. We 
expect to submit this plan to Ofwat later this year. 
 
FINANCIAL PERFORMANCE 
 
Revenue 
 
UU has delivered a good set of financial results for the year ended 31 March 
2013. Revenue increased by GBP71 million to GBP1,636 million, principally 
reflecting a 5.8% nominal (0.6% real price increase plus 5.2% RPI inflation) 
regulated price increase, partially offset by reduced volumes and the ongoing 
impact of customers switching to meters. The impact of meter switching was in 
line with our expectations while commercial and domestic volumes continued to 
be impacted by the persisting tough economic climate. We would expect to 
recover a substantial element of any regulated revenue shortfall through the 
regulatory methodology. 
 
Operating profit 
 
Underlying operating profit increased by 2% to GBP607 million, primarily as a 
result of an increase in revenue, largely offset by an expected increase in 
depreciation alongside higher infrastructure renewals expenditure, power and 
other operating costs. Reported operating profit increased by 2% to GBP605 
million. 
 
Investment income and finance expense 
 
The underlying net finance expense of GBP253 million was GBP14 million lower than 
last year, principally reflecting lower RPI inflation in respect of the group's 
index-linked debt with an eight month lag. The indexation of the principal on 
index-linked debt amounted to a net charge in the income statement of GBP86 
million, compared with a net charge of GBP100 million last year. The group had 
approximately GBP2.9 billion of index-linked debt as at 31 March 2013. The lower 
RPI indexation charge contributed to the group's average underlying interest 
rate of 4.9% being lower than the rate in 2011/12 of 5.5%. 
 
Reported investment income and finance expense of GBP300 million was GBP11 million 
lower than in 2011/12, principally reflecting a reduction in the underlying net 
finance expense. The GBP42 million net fair value loss in the year is largely due 
to losses on the regulatory swap portfolio, resulting from a further decrease 
in sterling interest rates during the period. The group uses these swaps to fix 
interest rates on a substantial proportion of its debt to better match the 
financing cash flows allowed by the regulator at each price review. The group 
fixed the majority of its non index-linked debt for the 2010-15 financial 
period, providing a net effective nominal interest rate of approximately 5%. 
 
Profit before taxation 
 
Underlying profit before taxation was GBP354 million, GBP27 million higher than 
last year due to the GBP13 million increase in underlying operating profit and 
the GBP14 million reduction in underlying finance expense. This underlying 
measure adjusts for the impact of one-off items, principally from restructuring 
and reorganisation within the business, and fair value movements in respect of 
debt and derivative instruments. Reported profit before taxation increased by GBP 
24 million to GBP305 million. 
 
Taxation 
 
The current taxation charge was GBP74 million in the year and the current 
taxation effective rate was 24%. This compares with 16% in the previous year 
which included a GBP16 million credit following agreement with the UK taxation 
authorities of prior years' taxation matters. 
 
The group has recognised a net deferred taxation credit of GBP52 million for the 
year, which primarily relates to a GBP53 million credit in respect of the change 
substantively enacted by the UK Government on 3 July 2012 to reduce the 
mainstream rate of corporation taxation from 24% to 23% with effect from 1 
April 2013.  A net deferred taxation credit of GBP77 million was recognised in 
the previous year, which included a GBP105 million credit reflecting a 2% staged 
reduction in the rate of corporation taxation. 
 
An overall taxation charge of GBP22 million has been recognised for the year 
ended 31 March 2013.  Excluding the deferred taxation impact relating to the 
future reduction in the corporation taxation rate, the total taxation charge 
would have been GBP75 million or 25% compared with a GBP74 million charge or 26% in 
the previous year. This reduction is principally due to the decrease in the 
mainstream rate of corporation taxation from 26% for 2011/12 to 24% for 2012/ 
13. 
 
The taxation benefit of GBP16 million relating to pension contributions for 
deficit funding has been recorded in the statement of comprehensive income, 
rather than the income statement, as the actuarial movements giving rise to the 
deficit were previously recorded there. Deferred taxation movements of GBP26 
million are also included in the statement of comprehensive income. The 
comparative prior year figures were a current taxation benefit of GBP33 million 
and a GBP29 million deferred taxation charge. 
 
The group made cash taxation payments during the year of GBP55 million. This was 
higher than the group's net taxation payment of GBP5 million in 2011/12 primarily 
reflecting a GBP35 million cash taxation inflow last year relating to prior 
years' taxation matters and also reflecting the higher levels of pension 
contributions made last year. 
 
Profit after taxation 
 
Underlying profit after taxation of GBP266 million was GBP25 million higher than 
the previous year, principally reflecting the increase in underlying profit 
before taxation. Reported profit after taxation was GBP282 million, compared with 
GBP311 million last year, as the increase in underlying profit was more than 
offset by a decrease in deferred taxation credits associated with the enactment 
of the reductions in corporation taxation rates between the two years. 
 
Earnings per share 
 
Underlying earnings per share increased from 35.3 pence to 39.1 pence. This 
underlying measure is derived from underlying profit after taxation. This 
includes the adjustments for the deferred taxation credits in both 2012/13 and 
2011/12, associated with the reductions in the corporation taxation rate. Basic 
earnings per share decreased from 45.7 pence to 41.4 pence, mainly due to the 
higher deferred taxation credit in 2011/12. 
 
Dividend per share 
 
The board has proposed a final dividend of 22.88 pence per ordinary share in 
respect of the year ended 31 March 2013. Taken together with the interim 
dividend of 11.44 pence per ordinary share, paid in February, this produces a 
total dividend per ordinary share for 2012/13 of 34.32 pence. This is an 
increase of 7.2%, compared with the dividend relating to the previous year, in 
line with group's dividend policy of targeting a growth rate of RPI+2% per 
annum through to at least 2015. The inflationary increase of 5.2% is based on 
the RPI element included within the allowed regulated price increase for the 
2012/13 financial year (i.e. the movement in RPI between November 2010 and 
November 2011). 
 
The final dividend is expected to be paid on 2 August 2013 to shareholders on 
the register at the close of business on 21 June 2013. The ex-dividend date is 
19 June 2013. 
 
Cash flow 
 
Net cash generated from continuing operating activities for year ended 31 March 
2013 was GBP631 million, compared with GBP560 million last year. This mainly 
reflected a reduction in the total pension contribution payments between the 
two years. The group's net capital expenditure was GBP642 million, principally in 
the regulated water and wastewater investment programmes. This excludes 
infrastructure renewals expenditure which is treated as an operating cost under 
International Financial Reporting Standards. 
 
Net debt including derivatives at 31 March 2013 was GBP5,451 million, compared 
with GBP5,076 million at 31 March 2012. This expected increase reflects 
expenditure on the regulatory capital expenditure programmes and payments of 
dividends, interest and taxation, alongside the accelerated pension deficit 
repair payments and an increase in the principal of our index-linked debt, 
partly offset by operating cash flows. 
 
Debt financing and interest rate management 
 
Gearing (measured as group net debt divided by UUW's regulatory capital value 
adjusted for actual capital expenditure) marginally increased to 60% at 31 
March 2013, compared with 59% at 31 March 2012, and is in the middle of Ofwat's 
55% to 65% assumed gearing range. The group now has a small pension surplus of 
GBP15 million, on an IFRS basis, compared with a deficit of GBP92 million as at 31 
March 2012. 
 
At 31 March 2013, UUW had long-term credit ratings of A3/BBB+ and United 
Utilities PLC had long-term credit ratings of Baa1/BBB- from Moody's Investors 
Service and Standard & Poor's Ratings Services respectively. The split rating 
reflects differing methodologies used by the credit rating agencies. In 
December 2012, Standard & Poor's put both the group's ratings on positive 
outlook, citing improving financial metrics and operational performance. 
 
Cash and short-term deposits at 31 March 2013 amounted to GBP202 million. In 
March 2013, UUW arranged a new GBP100 million, 10-year index-linked loan with an 
existing relationship bank. The group also renewed GBP150 million of existing 
bank facilities in the period. The group has headroom to cover its projected 
financing needs into 2015. 
 
The group has access to the international debt capital markets through its EUR7 
billion euro medium-term note programme which provides for the periodic 
issuance by United Utilities PLC and UUW of debt instruments on terms and 
conditions determined at the time the instruments are issued. The programme 
does not represent a funding commitment, with funding dependent on the 
successful issue of the debt securities. 
 
Long-term borrowings are structured or hedged to match assets and earnings, 
which are largely in sterling, indexed to UK retail price inflation and subject 
to regulatory price reviews every five years. 
 
Long-term sterling inflation index-linked debt is the group's preferred form of 
funding as this provides a natural hedge to assets and earnings. At 31 March 
2013, approximately 52% of the group's net debt was in index-linked form, 
representing around 31% of UUW's regulatory capital value, with an average real 
interest rate of 1.7%. The long-term nature of this funding also provides a 
good match to the company's long-life infrastructure assets and is a key 
contributor to the group's average term debt maturity profile which is 
approximately 25 years. 
 
Where nominal debt is raised in a currency other than sterling and/or with a 
fixed interest rate, to manage exposure to long-term interest rates, the debt 
is generally swapped to create a floating rate sterling liability for the term 
of the liability. To manage exposure to medium-term interest rates, the group 
fixed interest costs for a substantial proportion of the group's debt for the 
duration of the 2010-15 regulatory period at around the time of the price 
review. 
 
Following the 2009 price review, the group reassessed its interest rate hedging 
policy with a view to further reducing regulatory risk. To help address the 
uncertainty as to how Ofwat may approach the setting of the cost of debt 
allowance at the next price review in 2014, UU revised its interest rate 
management strategy to extend its fixed interest rate hedge out to a ten-year 
maturity on a reducing balance basis. The intention is that the effective 
interest rate, on the group's nominal debt, in any given year will, over time, 
be a ten-year rolling average interest rate. UU believes that this revised 
interest rate hedging policy, which provides for a longer fixing of interest 
rates, will put the company in a more flexible position to respond to whatever 
approach Ofwat adopts to the industry cost of debt in future. 
 
Liquidity 
 
Short-term liquidity requirements are met from the group's normal operating 
cash flow and its short-term bank deposits and supported by committed but 
undrawn credit facilities. In addition to its EUR7 billion euro medium-term note 
programme, the group has a EUR2 billion euro-commercial paper programme, both of 
which do not represent funding commitments. 
 
In line with the board's treasury policy, UU aims to maintain a robust headroom 
position. Available headroom at 31 March 2013 was GBP336 million based on cash, 
short-term deposits and medium-term committed bank facilities, net of 
short-term debt. This headroom is sufficient to cover the group's projected 
financing needs into 2015. 
 
UU believes that it operates a prudent approach to managing banking 
counterparty risk. Counterparty risk, in relation to both cash deposits and 
derivatives, is controlled through the use of counterparty credit limits. UU's 
cash is held in the form of short-term (generally no longer than three months) 
money market deposits with either prime commercial banks or with triple A rated 
money market funds. 
 
UU operates a bilateral, rather than a syndicated, approach to its core 
relationship banking facilities. This approach spreads maturities more evenly 
over a longer time period, thereby reducing refinancing risk and providing the 
benefit of several renewal points rather than a large single refinancing 
requirement. 
 
Pensions 
 
As at 31 March 2013, the group had an IAS 19 net retirement benefit, or 
pension, surplus of GBP15 million, compared with a net pension deficit of GBP92 
million at 31 March 2012. This GBP107 million positive movement principally 
reflects payments of GBP65 million in respect of accelerated, previously agreed, 
deficit repair contributions, payments under the inflation funding mechanism 
and investment returns exceeding expectation. Following the accelerated deficit 
repair contributions paid in the first half of 2012/13, the group completed 
early all scheduled deficit repair payments through to March 2015. 
 
The group has sought to adopt a more sustainable approach to the delivery of 
pension provision and prior to the start of the 2010-15 regulatory period 
amended the terms of its defined benefit pension schemes. UU stated previously 
that it would continue to evaluate its pensions investment strategy to de-risk 
further its pension provision and introduced an inflation funding mechanism, 
which facilitates a move to a lower risk investment strategy. This allowed UU 
to reduce the allocation of its pension assets to approximately 25% in equities 
and other high risk assets, down from 48% at 31 March 2010. In addition, UU has 
adopted the use of more prudent longevity assumptions. Over the last two 
financial years, the group also progressively increased its interest rate hedge 
and this has now been extended to around 90% of the pension scheme liabilities. 
Although any additional payments under the inflation funding mechanism would 
reduce financing outperformance, there would be a positive benefit to the 
pensions surplus or deficit position. 
 
From an accounting perspective, IAS 19 treats the inflation funding mechanism 
as a schedule of contributions rather than a pension scheme asset. This means 
that the liabilities position can change to reflect a change in market 
expectations of long-term inflation, without a commensurate movement in assets. 
This accounting treatment means that there is likely to be a degree of 
volatility in future IAS 19 pension valuations. 
 
The last actuarial valuations of the United Utilities Pension Scheme and the 
United Utilities PLC Group of the Electricity Supply Pension Scheme were 
carried out as at 31 March 2010. The valuations are performed on a triennial 
basis, and therefore discussions will take place over the coming months between 
the group and the trustees regarding the basis of the 31 March 2013 
valuations.  The actuarial valuations are based on scheme specific factors 
which may result in a different assessment of the pension schemes' position to 
the IAS19 numbers reported in the group's financial statements. 
 
Further detail is provided in note 8 ("Retirement benefit surplus/(obligations) 
") of these condensed consolidated financial statements. 
 
BOARD CHANGES 
 
Paul Heiden will stand down at the forthcoming AGM, on 26 July 2013, after over 
seven years as a non-executive director. Brian May, who was appointed as a 
non-executive director on 1 September 2012, will replace Paul as chair of both 
the audit and risk committee and the treasury committee. 
 
Underlying profit 
 
In considering the underlying results for the period, the directors have 
adjusted for the items outlined in the table below to provide a more 
representative view of business performance. Reported operating profit and 
profit before taxation from continuing operations are reconciled to underlying 
operating profit, underlying profit before taxation and underlying profit after

PRINCIPAL RISKS AND UNCERTAINTIES 
 
We manage risk through line management supported by our corporate risk 
management framework which aims for continuous improvement. With an overarching 
mandate from and commitment by the group board, the framework consists of four 
key areas: governance; approach; guidance; and process. 
 
The application of our framework involves regular review of internal and 
external risk environments, the assessment of factors that will limit or 
prevent the achievement of our company objectives and the prioritised 
implementation of controls and mitigation to manage the exposure and build 
resilience. 
 
The audit and risk committee regularly reviews the framework's effectiveness 
and our compliance with it. There is also twice yearly formal reporting of the 
most significant risks and profile summary to the executive and the group 
board. These activities facilitate the determination of the nature and extent 
of those risks we are willing to take in pursuing our objectives and accord 
with good corporate governance practice. 
 
Key developments during the year 
 
Regulatory related risks have featured prominently in our risk profile over the 
last 12 months with key areas of focus typically being the Government's market 
reform agenda and Ofwat's proposals for future price limits. 
 
In addition, the risk of potential change in RPI methodology with the potential 
impact to RCV and income continues to exist but is a reduced risk for the 
group. This risk was highlighted in our half year accounts but the Office of 
National Statistics has now recommended no change to the methodology. 
 
There are two on-going pieces of material litigation worthy of note but, based 
on the facts and matters currently known to us and the provisions carried in 
the group's statement of financial position, our directors are of the opinion 
that the possibility of the disputes having a material adverse effect on the 
group's financial position is remote. 
 
Government market reform agenda 
 
The Government's White Paper (Water for Life) highlighted key policy priorities 
for the water industry. A draft Water Bill was published on 10 July 2012 and 
incorporates changes to legislation that would be required to enable many of 
the changes set out in the White Paper. These include measures to introduce 
competition and the removal of barriers to entry. The scale and impact of 
retail and upstream competition will depend on the mechanisms set out in an 
expected new draft bill and what ultimately becomes legislation. As a result 
and until this publication, there is significant uncertainty about the 
potential impacts; however, these could include: increased costs, reduced 
income and reduced confidence in the RCV mechanism leading to a rise in future 
costs of borrowing. 
 
Control/Mitigation 
 
We have been fully engaged, as has the whole industry, in all Government and 
Ofwat consultations in relation to competition and industry reform. 
 
We are also making determined efforts to retain customers in area, win out of 
area customers and prepare for a more competitive environment and the potential 
opportunities that this may bring. 
 
Future price limits and the price control review 2014 
 
In May 2012, Ofwat published a document setting out the key principles it 
expects to follow in future price reviews. Ofwat then undertook a lengthy and 
ongoing consultation over its proposals for reform of the methodology and 
approach for setting prices from 2015, the most recent of which was the draft 
methodology issued on 28 January 2013. The principal decision to date is that 
Ofwat will set two binding retail price controls (one for household and one for 
non-household) and two binding wholesale controls (one for water and one for 
wastewater). Other proposals include: household/non-contestable retail cost 
recovery based on an average cost to serve; the introduction of a new `Totex' 
menu approach to assessing cost assumptions; the setting of a lower cost of 
capital and the potential for different approaches to sharing the benefits of 
outperformance between shareholders and customers. These areas contribute to a 
wider risk of failing to achieve a successful Final Determination following 
Ofwat's price control review which could result in loss of income and profit, 
significant cost recovery shortfall, a reduction in allowed expenditure (both 
capital and operating expenditure) and the ability to outperform. There will 
also be additional costs for preparing for and administrating separate price 
controls for retail and wholesale. 
 
Control/Mitigation 
 
We have raised and explained our concerns with Ofwat and, where appropriate, 
made alternative proposals as part of the consultation process. We continue to 
make strong representation to Ofwat on these issues, particularly in relation 
to the `cost to serve' proposals. 
 
More generally, a successful price control review (meeting the needs of 
customers and stakeholders) is being targeted through a dedicated PR14 
programme team whose activities are focused on appropriate deliverables and 
stakeholder engagement. The final price review methodology proposals are due to 
be issued later this summer. 
 
Failure to comply with applicable law or regulations 
 
We are subject to various UK and international laws and regulations associated 
with water and wastewater service, health and safety, the environment, property 
/land management and the general running of a company. If we fail to comply, or 
become involved in third party proceedings including civil actions by third 
parties for infringement of rights or nuisance, we could face a range of 
outcomes. These include financial penalties (of up to 10 per cent of relevant 
regulated turnover), the imposition of an enforcement order requiring 
additional capital/operating expenditure, or compensation following litigation. 
In more extreme circumstances, impacts could ultimately include the revocation 
of our licence to operate or the appointment of a special administrator. 
 
The UK Government has lost a case in the Court of Justice of the European Union 
relating to the Government's approach to enforcement of the Urban Waste Water 
Treatment Directive (the `Whitburn' case). The Directive relates to waste water 
discharges and, if this case leads to a change in the law or enforcement of it, 
our capital investment programme and associated funding requirements could 
change. 
 
Control/Mitigation 
 
We have robust processes in place to identify risks to our compliance with 
legal and regulatory obligations. This includes the continual monitoring of 
legislative and regulatory developments, the training of employees in new 
developments and the participation in consultations to influence their outcome, 
either directly or through industry trade associations for wider issues. 
Funding for any additional compliance costs in our regulated business is sought 
as part of the price determination process. We also robustly defend litigation 
where appropriate and seek to minimise our exposure by establishing a provision 
and seeking recovery wherever appropriate. 
 
No decision has been made on potential change to the law or its enforcement 
following `Whitburn' but we are engaged with the industry and industry trade 
associations on this issue. 
 
Material litigation 
 
In February 2009, United Utilities International Limited (UUIL) was served with 
notice of a multiparty `class action' in Argentina related to the issuance and 
payment default of a US$230 million bond by Inversora Eléctrica de Buenos Aires 
S.A. (IEBA), an Argentine project company set up to purchase one of the 
Argentine electricity distribution networks which was privatised in 1997. UUIL 
had a 45 per cent shareholding in IEBA which it sold in 2005. The claim is for 
a non-quantified amount of unspecified damages and purports to be pursued on 
behalf of unidentified consumer bondholders in IEBA. UUIL has filed a defence 
to the action and will vigorously resist the proceedings given the robust 
defences that UUIL has been advised that it has on procedural and substantive 
grounds. 
 
In March 2010, Manchester Ship Canal Company (MSCC) issued proceedings seeking, 
amongst other relief, damages alleging trespass against United Utilities Water 
PLC (UUW) in respect of UUW's discharges of water and treated effluent into the 
canal. UUW filed a Defence and Counterclaim in support of its believed 
entitlement to make discharges into the canal without charge and await MSCC's 
response. Although UUW won a `summary judgment' application against MSCC in 
January on a significant element of the claim, MSCC subsequently appealed to 
the Court of Appeal who dismissed UUW's summary judgment. UUW was then granted 
permission to appeal to the Supreme Court, the hearing to be in the next 6 to 
12 months. 
 
Control/Mitigation 
 
The group faces the general risk of litigation in connection with its 
businesses. In most cases, liability for litigation is difficult to assess or 
quantify; recovery may be sought for very large and/or indeterminate amounts 
and the existence and magnitude of liability may remain unknown for substantial 
periods of time. The group robustly defends litigation, where appropriate, and 
seeks to minimise its exposure to such claims by early identification of risks 
and compliance with its legal and other obligations. Based on the facts and 
matters currently known and the provisions carried in the group's statement of 
financial position, the directors are of the opinion that the possibility of 
the disputes referred to in this risk section having a material adverse effect 
on the group's financial position is remote. 
 
Pension deficit risk 
 
The group participates in a number of pension arrangements. Estimates of the 
amount and timing of future funding for these schemes are based on various 
actuarial assumptions and other factors including, among other things, the 
actual and projected market performance of the scheme assets, future long-term 
bond yields, average life expectancies and relevant legal requirements. The 
impact of these assumptions and other factors may require the group to make 
additional contributions to these pension schemes which, to the extent they are 
not recoverable under the regulatory price determination process, could 
materially adversely affect the group's financial position. 
 
Control/Mitigation 
 
In the 2009 water price review, Ofwat took account of broadly 50 per cent of 
the pension deficit shown in UUW's final business plan over a 10-year period 
(subject to reaffirmation at the next price review) and allowed for half of 
this deficit when setting its overall price controls for the 2010-15 period. In 
response to the size of our ongoing pension risks and pension costs we 
introduced a series of changes for employees in defined benefit (DB) schemes. 
These changes, which came into force on 31 March 2010, should result in reduced 
costs and risks, including deficit, associated with DB liabilities in the 
future. In conjunction with the trustees we continue to monitor and to look to 
reduce the investment strategy risks for the pension schemes, including our 
exposure to investment risks. We are also engaged with Ofwat on the appropriate 
allowance for pension deficits for the next price review period. 
 
Counterparty risk 
 
The group participates in treasury activities including the depositing of cash 
and holding of derivatives and foreign exchange instruments. Although we do not 
consider there to be an imminent exposure, a potential loss of deposits, 
financial assets or hedge due to bank failure, error or delay in receiving 
funds from a bank or sequestration could impact cash flow, the ability to meet 
debt obligations, credit rating and cost of borrowing. 
 
Control/Mitigation 
 
Risks from treasury activities are covered by policies set by our treasury 
committee with operational management the responsibility of our treasury 
department. These include establishing a total credit limit for each 
counterparty which comprises a counterparty credit limit and an additional 
settlement limit to cover intra day gross settlement cash flows. In addition, 
potential derivative exposure limits are also established to take account of 
potential future exposures. These limits are based on a number of factors, 
including the credit rating and the size of the asset base of the individual 
counterparty. In respect of cash, short-term deposits and derivative financial 
instruments, the group does not have a material exposure to any financial 
instruments based within the Eurozone with the exception of Germany and has not 
experienced any credit issues in the financial year. 
 
Customer service risk 
 
Failure to deliver good customer service can be caused by failures in supply 
and quality requirements (see below) and also the effectiveness of 
communication and response. The Service Incentive Mechanism (SIM), introduced 
by Ofwat for the 2010-15 period, replacing the Overall Performance Assessment 
(OPA), compares companies' performance in terms of the number of `unwanted' 
contacts received from customers and how well a company then deals with those 
contacts. Depending on UUW's relative performance under SIM it could receive a 
revenue penalty (up to 1 per cent of turnover in 2010-15) or reward (up to 0.5 
per cent of turnover in 2010-15) when price limits are next reset in 2014. 
 
Control/Mitigation 
 
The group has been monitoring and measuring customer satisfaction for a number 
of years and results have been improving consistently. We have already improved 
our SIM score as detailed in our KPIs. We have an overall customer experience 
programme covering a range of initiatives to improve customer service, 
responding to our customers' requirements and focusing on people, processes and 
systems. The company's focus is on ensuring right first time service delivery 
to our customers, thus avoiding the need for `unwanted' contacts and reducing 
associated operating costs. Where `unwanted' contacts do arise, there is a 
clear focus on identifying the root causes to improve the overall customer 
experience and the SIM score. These actions are intended to ensure that the 
company's performance under SIM is optimised thereby mitigating the risk of a 
penalty at the next price review. 
 
Bad debt risk 
 
The service we provide is predominantly in the North West of England where the 
level of socio-economic deprivation is much higher than in any other region, 
leading to, amongst other things, an increased risk of bad debt. The law 
prohibits the disconnection of a water supply from certain premises including 
domestic dwellings as a method of enforcing payment. 
 
Control/Mitigation 
 
Bad debt risk is managed in-house by the customer collections department whose 
approach includes the adoption of best practice collection techniques and 
segmentation of customers based on their credit risk profile. 
 
Operational service risk 
 
The group controls and operates water and wastewater networks and maintains the 
associated assets with the objective of providing a continuous service. 
Physical, environmental, technological or human factors, either within or 
outside the company's control, could result in impacts ranging from a decline 
in performance to interruptions and environmental impact. Ofwat could make 
financial adjustments at the next price review if corrective actions do not 
restore service to the required reference levels for each of their 
serviceability measures and could go on to force additional operating or 
capital expenditure if performance were to continue to decline. Additionally, 
depending on the nature and extent of an operational service incident, we could 
be fined for breaches of statutory obligations, be held liable to third parties 
or be required to provide an alternative water supply of equivalent quality, at 
additional cost. 
 
Control/Mitigation 
 
Operational processes combined with the capital investment programme are 
targeted to maintain stable serviceability of our water and wastewater assets 
and to minimise the risk of significant operational events occurring. The 
various indicators of performance are closely and routinely monitored by 
management. There are also governance and inspection regimes for key 
infrastructure assets such as aqueducts, dams, reservoirs and treatment works. 
Where adverse trends in performance or asset integrity develop, corrective 
action is identified and taken. The sustainability and resilience of our water 
supply is also managed through regional aqueduct networks allowing flexibility 
and we operate emergency plans, incident management and disaster recovery 
processes for the response and/or recovery of operational service failures. 
Insurance cover is also in place against loss and liabilities associated with 
significant risks. 
 
Capital delivery risk 
 
Our core business requires significant capital expenditure, particularly in 
relation to new and replacement plant and equipment for water and wastewater 
networks and treatment facilities. 
 
Delivery of our capital investment programmes could be affected by a number of 
factors including adverse legacy effects of earlier capital investments (such 
as increased maintenance, repair, reinstatement or renewal costs) or amounts 
budgeted in prior capital investment programmes proving insufficient to meet 
the actual amount required. This may affect our ability to meet regulatory and 
other environmental performance standards. 
 
Control/Mitigation 
 
Capital investment programmes are regularly monitored to identify the risk of 
time, cost and quality variances from plans and budgets and to identify, where 
possible, any appropriate opportunities for outperformance and any necessary 
corrective actions. Executive directors are incentivised, as part of their 
bonusable measures, on time, cost and quality of delivery of our capital 
investment programme. 
 
Secure supply of safe clean drinking water risk 
 
A secure and reliable supply of safe, clean drinking water is critical for our 
way of life. There are several events, either within or outside our control, 
that could put at risk this key requirement. These include inadequate supply 
and demand prediction, leakage performance issues, operational or asset 
failures, changes to abstraction licences, low rainfall or malicious acts. 
Depending on the nature and extent of these circumstances, the impact to the 
group may include: failure to meet the security of supply index or quality 
standards with associated regulatory penalties, increased frequency of hosepipe 
bans and drought permits and additional operational activity and cost. In 
extreme and remote circumstances, impacts may include unavoidable water 
resource shortfalls or an impact on public health. 
 
Control/Mitigation 
 
Our management of water catchments is designed to ensure reliable yields of 
good quality raw water. In addition, our water resources management plan 
compares future demand with availability, analyses historic droughts and 
climate change data and seeks to inform the delivery of supply enhancements and 
demand reductions. It covers leakage reduction programmes, enhanced water 
efficiency and network enhancements. We also maintain a drought management plan 
which includes processes, supporting communication plans and options for 
reserve supplies. 
 
Our treatment of water is based on quality assurance procedures and water 
supply is through an increasingly integrated network. Security measures are in 
place to protect these assets and our capital investment programme targets 
improvements to water quality and supply. This is all supported by testing 
regimes through our scientific services department and drinking water safety 
plans to ensure that risks to drinking water quality are identified and managed 
across our entire network. We also operate emergency and incident management 
processes should there ever be a need for alternative water supply of 
equivalent quality. 
 
Significant and catastrophic events 
 
Our core activity involves the building, control and operation of water and 
wastewater networks and the maintenance of the associated assets with the 
objective of providing a continuous service. This includes major construction 
work and operations above and below ground and includes the use of vehicles, 
equipment and chemicals subject to a variety of physical and environmental 
factors/conditions. In exceptional and remote circumstances, such as the 
failure of an asset, an element of a network or supporting systems, plant or 
equipment, the impact could be significantly greater than operational service 
failures set out in other risks in this section. These could range from 
environmental impact, economic and social disruption to loss of life. Such 
consequences may arise due to a number of circumstances either within or 
outside our control e.g. human error, an individual's malicious intervention or 
unavoidable resource shortfalls. 
 
Whilst we seek to ensure that we have appropriate processes and preventative 
controls in place, there can be no certainty that such measures will be 
effective in preventing or, when necessary, managing large-scale incidents to 
the satisfaction of our customers, regulators, Government and the wider 
stakeholder community. We could be fined for breaches of statutory obligations 
or be held liable to third parties or be required to provide an alternative 
water supply of equivalent quality, which could increase our costs. 
 
Control/Mitigation 
 
We have developed and continue to focus on a strong safety and health culture 
throughout the organisation and seek to achieve the highest safety standards 
not simply to comply with legislation but to contribute to our overall business 
performance while protecting employees, contractors and the public from harm. 
In support of this, the business operates a Health and Safety Management System 
(HSMS) which sets out minimum expectations and requirements including 
monitoring the occupational health of individuals when appropriate. 
 
We operate long-standing, well tested and appropriately resourced incident 
response and escalation procedures. Our processes continue to be refined 
alongside related risk management and business continuity procedures which 
complement the governance and inspection regimes for key infrastructure assets 
such as aqueducts, dams, reservoirs and treatment works. Disaster recovery 
processes also exist for the recovery of IT applications, all recognising that 
possible events can have varying causes, impacts and likelihoods. The 
sustainability and resilience of our water supply is also managed through 
regional aqueduct networks which are enhanced by the West East Link pipeline. 
We also maintain insurance cover in relation to losses and liabilities likely 
to be associated with such significant risks, although potential liabilities 
arising from a catastrophic event could exceed the maximum level of insurance 
cover that can be obtained cost-effectively. The licence of the regulated 
business also contains a `shipwreck' clause that, if applicable, may offer a 
degree of recourse to Ofwat/customers (by way of interim determination) in the 
event of a catastrophic incident.

NOTES 
 
1. Basis of preparation and accounting policies 
 
The condensed consolidated financial statements for the year ended 31 March 
2013 have been prepared in accordance with the Disclosure and Transparency 
Rules of the Financial Services Authority. 
 
The accounting policies, presentation and methods of computation have been 
prepared on a basis consistent with the United Utilities Group PLC full year 
financial statements which are prepared in accordance with International 
Financial Reporting Standards (IFRSs) as adopted by the European Union (EU) 
that are effective for the year ended 31 March 2013. 
 
The adoption of the following standards and interpretations, at 1 April 2012, 
had no material impact on the group's financial statements: 
 
Amendments to IFRS 7 `Financial Instruments' 
 
This amendment introduces new disclosure requirements about transfers of 
financial assets which will impact the group only if it enters into any 
relevant transactions in the future. 
 
The condensed consolidated financial statements do not include all of the 
information and disclosures required for full annual financial statements, do 
not comprise statutory accounts within the meaning of section 434 of the 
Companies Act 2006 and should be read in conjunction with the group's annual 
report and financial statements for the year ended 31 March 2013. 
 
The comparative figures for the year ended 31 March 2012 do not comprise the 
group's statutory accounts for that financial year. Those accounts have been 
reported upon by the group's auditor and delivered to the registrar of 
companies. The report of the auditor was unqualified and did not include a 
reference to any matters to which the auditor drew attention by way of emphasis 
without qualifying their report and did not contain a statement under section 
498(2) or (3) of the Companies Act 2006. 
 
Going concern 
 
The directors have a reasonable expectation that the company has adequate 
resources available to it to continue in operational existence for the 
foreseeable future and have therefore continued to adopt the going concern 
policy in preparing the financial statements.  This conclusion is based upon, 
amongst other matters, a review of the group's financial projections together 
with a review of the cash and committed borrowing facilities available to the 
group as well as consideration of the group's capital adequacy. In addition, 
the directors considered, amongst other matters, the regulator's legal duty to 
ensure that United Utilities Water PLC is able to finance its activities. 
 
2. Segmental reporting 
 
The board of directors of United Utilities Group PLC (the board) is provided 
with information on a single segment basis for the purposes of assessing 
performance and allocating resources. The board reviews revenue, underlying 
operating profit, operating profit, assets and liabilities at a consolidated 
level. In light of this, the group has a single segment for financial reporting 
purposes and therefore no further detailed segmental information is provided in 
this note.

The group has fixed interest costs for a substantial proportion of the group's 
net debt for the duration of the regulatory pricing period. Following the 
revision in the prior year to its interest rate management strategy, the group 
has continued to extend the fixing of interest rates out to a one year maturity 
on a reducing balance basis, seeking to lock in a 10-year rolling average of 
10-year interest rates, on the group's nominal liabilities. In addition, the 
group has hedged currency exposures for the term of each relevant debt 
instrument. The group has hedged its position through the use of interest rate 
and cross currency swap contracts where applicable. 
 
The underlying net finance expense for the continuing group of GBP252.8 million 
(2012: GBP267.1 million) is derived as shown in the table below.

The deferred taxation credit for the year ended 31 March 2013 includes a credit 
of GBP53.0 million to reflect the change enacted on 3 July 2012 to reduce the 
mainstream rate of corporation tax from 24 per cent to 23 per cent effective 
from 1 April 2013. A related deferred taxation charge of GBP0.9 million is 
included within items taken directly to equity. 
 
The deferred taxation credit for the year ended 31 March 2012 includes a credit 
of GBP104.6 million to reflect the change enacted on 5 July 2011 to reduce the 
mainstream rate of corporation tax from 26 per cent to 25 per cent and the 
subsequent change enacted on 26 March 2012 to reduce the mainstream rate of 
corporation tax further to 24 per cent effective from 1 April 2012. A related 
deferred taxation charge of GBP3.9 million is included within items taken 
directly to equity. 
 
There will be a further phased reduction in the mainstream rate of corporation 
tax to 20 per cent effective from 1 April 2015. The total deferred taxation 
credit in respect of this further reduction is expected to be in the region of 
GBP150.0 million. 
 
For a group of our size, negotiations with tax authorities in relation to tax 
returns can span a number of years. The net adjustment of GBP0.7 million (2012: 
0.4 million) in respect of prior years relates to those matters agreed in the 
current year.

5. Discontinued operations 
 
Discontinued operations represent the retained obligations in respect of 
businesses sold in prior years. In accordance with IFRS 5 `Non-current assets 
held for sale and discontinued operations,' the post-tax results of 
discontinued operations are disclosed separately in the consolidated income 
statement and consolidated statement of cash flows. 
 
The profit after taxation from discontinued operations is analysed as follows:

The profit after taxation from discontinued operations for the year ended 31 
March 2013 relates primarily to the release of accrued costs of disposal in 
respect of certain elements of the group's non-regulated disposal programme. 
 
6. Earnings per share 
 
Basic and diluted earnings per share are calculated by dividing profit after 
taxation by the following weighted average number of shares in issue: 
 
                                                               Basic    Diluted 
                                                             million    million 
 
Year ended 31 March 2013                                       681.9      682.8 
 
Year ended 31 March 2012                                       681.8      682.2 
 
The difference between the weighted average number of shares used in the basic 
and diluted earnings per share calculations arises due to the group's operation 
of share-based payment compensation arrangements. The difference represents 
those ordinary shares deemed to have been issued for no consideration on the 
conversion of all potential dilutive ordinary shares in accordance with IAS 33 
`Earnings per Share'. 
 
The basic and diluted earnings per share for the current and prior years are as 
follows: 
 
                                                         Year ended Year ended

The proposed final dividends for the years ended 31 March 2013 and 31 March 
2012 were subject to approval by equity holders of United Utilities Group PLC 
and hence have not been included as liabilities in the consolidated financial 
statements at 31 March 2013 and 31 March 2012 respectively. 
 
The final dividend of 22.88 pence per ordinary share (2012: final dividend of 
21.34 pence per ordinary share) is expected to be paid on 2 August 2013 to 
shareholders on the register at the close of business on 21 June 2013. The 
ex-dividend date for the final dividend is 19 June 2013. 
 
The interim dividend of 11.44 pence per ordinary share (2012: interim dividend 
of 10.67 pence per ordinary share) was paid on 1 February 2013 to shareholders 
on the register at the close of business on 19 December 2012. 
 
8. Retirement benefit surplus/(obligations)
