million this year in our network, maintaining and improving services, providing 
environmental benefits and supporting the local economy. 
 
"We are discounting prices next year so that customers do not pay the full 
allowed price increase, meaning that, on average, bills will go up by no more 
than inflation. We are also committing to further support for customers 
struggling to pay. This is in addition to the previously announced reinvestment 
of GBP240 million of outperformance for the benefit of our customers and the 
environment. 
 
"Our business plan for the next five-year period means that customers would 
benefit from below inflation average household bills for the decade to 2020. We 
have sought the views of over 27,000 customers, as well as consulting with our 
regulators, to deliver a plan which we believe strikes the right balance for 
all our stakeholders. This includes a substantial capital investment programme 
to meet our environmental obligations and deliver further customer and economic 
benefits."

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 - Since 2010, every year we have 
continued to improve the customer experience, as demonstrated through Ofwat's 
customer service measure the service incentive mechanism (SIM). Over the two 
years to 2012/13, we have moved up from last position to joint fifth, among the 
ten water and sewerage companies, on Ofwat's combined SIM assessment. In the 
first half of 2013/14, we continued our progress and have improved our score on 
Ofwat's qualitative SIM measure, as we narrow the gap further to the leading 
performers, although recognise that we still have more to do. Following a 40% 
reduction in written complaints in 2012/13 (best improvement in sector), 
complaints have continued to fall and we are pleased to again have zero 
complaints warranting investigation by the Consumer Council for Water in the 
first half of 2013/14. 
 
* Strong operational performance - We performed well again across a broad front, 
as measured in Ofwat's latest (2012/13) key performance indicators report. The 
balance of ratings across the fourteen assessments indicates that UU is again 
an above average performer, 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 over 90% for the first 
half of 2013/14. We met our water and wastewater asset serviceability standards 
in 2012/13 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. We have now invested just over GBP2.4 billion across the first three and 
a half years of this regulatory period, as we have sought to deliver a smoother 
investment profile to support efficient delivery of outputs and reduce risk. 
 
* Leakage target - We have met or outperformed our regulatory leakage target 
for seven consecutive years and our aim is to meet the target each year. 
 
* 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. As 
outlined previously, we expect to reinvest around GBP240 million of capex and 
financing outperformance, over 2010-15, for the benefit of our customers and 
the environment. 
 
* Corporate responsibility - We retained a `World Class' rating in the Dow 
Jones Sustainability Index for the sixth consecutive year. We also have the 
highest `Platinum Big Tick' ranking in Business in the Community's Corporate 
Responsibility Index. We are one of only seven FTSE 100 companies to hold both 
accolades. 
 
* Extending our presence in the retail water marketfor business customers - We 
have been building our capability over the last two years to help ensure we are 
in a strong position as the competitive business retail market evolves and are 
very active in this expanding market. After attaining a Scottish water supply 
licence in 2012 we have already won over 50 customers, covering over 1,500 
sites and representing future annual revenue of around GBP6 million. We are now 
the second largest water retailer in Scotland. We also have a significant 
pipeline of opportunities and are continuing to develop our range of 
value-added services. 
 
Financial overview 
 
The group has delivered another good set of financial results for the six 
months ended 30 September 2013. 
 
* Revenue - up by GBP30 million to GBP853 million, principally as a result of the 
impact of the regulated price increase for 2013/14 of 4.0% nominal (1.0% real 
price increase, plus 3.0% RPI inflation). This follows on from real price 
decreases of 4.3% in 2010/11 and 0.2% in 2011/12, with an allowed real price 
increase of 0.6% in 2012/13. 
 
* Underlying operating profit - increased by GBP29 million to GBP343 million as the 
company tightly managed its cost base, keeping total cost increases below 1%. 
 
* Capex - total regulatory capital investment in the half year, including GBP78 
million of infrastructure renewals expenditure, was GBP407 million, representing 
an increase of 15% compared with the first half of last year, reflecting 
continued good progress on the capital investment programme. 
 
* Underlying profit before taxation - up GBP27 million, at GBP216 million, 
marginally below the increase in underlying operating profit as net finance 
expense increased slightly, mainly due to higher levels of index-linked debt. 
 
* Reported profit after taxation - this benefited from a GBP159 million deferred 
taxation credit, which follows the UK Government's announced staged 3% 
reduction in the mainstream taxation rate down to 20% by 2015/16. A similar 
credit of GBP53 million, reflecting a 1% reduction in the mainstream taxation 
rate, was recognised in the first half of 2012/13. Reported profit after 
taxation also benefitted from a current taxation credit of GBP122 million and a 
deferred taxation credit of GBP3 million, both relating to recently agreed 
matters with Her Majesty's Revenue and Customs (HMRC) in relation to prior 
years, covering a period of over ten years in total. 
 
* Agreement with HMRC - this agreement principally relates to revised taxation 
treatment with regard to capital expenditure, particularly in respect of the 
abolition of industrial buildings allowances in 2008. The total taxation credit 
to the income statement of GBP125 million includes deferred taxation and the 
release of an accounting accrual, which are non-cash items. We expect to 
receive a cash taxation benefit of around GBP90 million over the next two years 
relating to the revised capex taxation treatment, of which a GBP15 million cost 
was borne by shareholders in the latter part of the previous regulatory period. 
We are proposing to share the GBP75 million net cash benefit with customers. We 
are proposing a special customer discount of cGBP20 million to offset the allowed 
real price increase for 2014/15 and we are committing to further support of GBP17 
million, through additional contributions to our trust fund, for customers who 
are struggling to pay. We intend to use the balance of cGBP38 million for future 
sharing with customers. In addition, we estimate that there will be taxation 
savings of around GBP90 million in the 2015-20 period, all of which will flow 
through to customers. 
 
* Capital structure - the group has a robust capital structure and gearing 
(measured as group net debt to regulatory capital value) as at 30 September 
2013 was 59%, comfortably within 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 with a stable outlook. 
 
* Financing headroom - the group benefits from headroom to cover its projected 
financing needs into 2015, with substantially all term debt due in the 2010-15 
period already repaid. This provides good flexibility in terms of when and how 
further debt finance is raised to help refinance maturing debt and fund the 
regulated capital investment programme. 
 
* Dividend - in line with its policy, the board has declared an interim 
dividend of 12.01 pence per ordinary share. 
 
PRICE REVIEW 2014 - BUSINESS PLAN 
 
On 2 December 2013, we will submit our business plans, covering the 2015-20 
period, to Ofwat. Following a period of extensive consultation with around 
27,000 customers and other key stakeholders, we believe our plans strike the 
right balance for all parties. Supported by customer research and significant 
cost saving initiatives, we are proposing below inflation average household 
bills across 2015-20. This would mean that our customers would benefit from 
below inflation average household bills for the decade to 2020. Our plan will 
include a substantial capital investment programme to help us meet our 
environmental obligations, alongside maintaining and improving services for 
customers. 
 
OUTLOOK 
 
Our sustained focus on operational performance, combined with continued 
substantial investment in our assets, will deliver further benefits for our 
customers and the environment. We are encouraged by our progress on Ofwat's 
service incentive mechanism and our strong operational performance and believe 
we can improve further. We remain confident of delivering our 2010-15 
regulatory outperformance targets, where we are ahead of schedule. 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 are submitting our 2015-20 business plan to Ofwat, which we 
believe strikes the right balance for all our stakeholders, and will continue 
to actively engage with our regulators as we look forward to the draft and 
final determinations from Ofwat next year. 
 
OPERATIONAL PERFORMANCE 
 
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 
 
Our continuing strong focus on dealing effectively with customer enquiries has 
helped us deliver further improvements in our performance on Ofwat's service 
incentive mechanism (SIM). Following on from a 40% reduction in written 
complaints in 2012/13 (the biggest improvement in the water sector), complaints 
have continued to fall in the first half of 2013/14. In addition, the number of 
customer complaints made to the Consumer Council for Water (CCW) in the first 
half of 2013/14 has reduced by a further 12%, compared with the first half of 
2012/13. We are pleased to report that the total number of escalated complaints 
assessed by the CCW was again zero in the first half of 2013/14. This has 
helped us improve our SIM performance further, as detailed in the KPIs section 
below. This places us in a good position as we aim to avoid a SIM penalty. Our 
strong overall operational performance, as measured by Ofwat's latest (2012/13) 
KPIs report, has also contributed to improving customer satisfaction. 
 
Our customers continue to benefit from our robust water supply and demand 
balance and high levels of water supply reliability. In addition, we continue 
to supply a high level of water quality, with mean zonal compliance continuing 
to be over 99.9%. 
 
We have continued to invest heavily in schemes designed to mitigate the risk of 
flooding of our customers' homes, including incidence based targeting on areas 
more likely to experience flooding and defect identification through CCTV sewer 
surveys. Our wastewater network will continue to benefit from significant 
investment going forward as we adapt to weather patterns likely to result from 
climate change. 
 
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 optimising water treatment to reduce discoloured water events. 
 
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). 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 aligns with Ofwat's target. 
 
* Service incentive mechanism (SIM) - UU continued its progress on Ofwat's 
combined SIM assessment for 2012/13, moving up a further three places to joint 
13th of the 21 water companies, compared with 2011/12. This represents joint 
fifth position among the ten water and sewerage companies. Progress has 
continued in the first six months of 2013/14, with a further improvement in the 
quantitative SIM score, compared with the first half of 2012/13. On the 
qualitative measure, UU has improved its 2013/14 average score by 0.10 points 
to 4.53 points which represents an above average score and narrows the gap to 
the leading performers. From 2013/14, Ofwat assesses SIM out of 19 water 
companies and UU's qualitative SIM improvement moves it to 10th position. Our 
continued progress is encouraging, as we aim to move to the first quartile in 
the medium-term. 
 
Lowest sustainable cost 
 
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. 
 
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. 
 
We have substantially locked in the cost of our power requirements through to 
2015, via hedging, securing outperformance across the 2010-15 period. 
 
We are continuing to enhance our proactive approach to debt collection and are 
implementing a detailed action plan. We recognise the financial difficulties 
facing many of our customers and provide a range of options to help those who 
are struggling to pay their bills and we have helped many customers back onto 
manageable payment plans. We have again delivered a good performance and have 
sustained bad debts at 2.2% of regulated revenue for the first half of 2013/14, 
consistent with the 2012/13 full year position. 
 
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. 
Further details on the group's pension provision are provided in the pensions 
section. 
 
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. Regulatory capital investment in the half year, including GBP78 
million of infrastructure renewals expenditure, was GBP407 million and we expect 
to deliver at least GBP800 million in 2013/14. We improved our internal Time: 
Cost: Quality index (TCQi) score from around 50% in 2010/11 to approximately 
90% in 2012/13 and have delivered over 90% in the first half of 2013/14. We 
received a shortfalling revenue penalty of over GBP80 million at the last price 
review in 2009 but, with our improved TCQi performance, we aim to avoid, or at 
least minimise, any revenue penalties at the 2014 price review. We remain on 
track to deliver the five-year programme within the regulatory allowance of 
around GBP3.5 billion (excluding costs associated with private sewers and 
transitional investment) and we are reinvesting any capex outperformance to 
deliver further customer benefits. 
 
The transfer of private sewers around two years ago has gone well and is now 
fully embedded within our 'business as usual' activities. In the first half of 
2013/14, private sewers opex was GBP5 million and capex was GBP16 million, of which 
GBP9 million was IRE. This level of spend is broadly in line with our 
expectations and there is no change to our 2011-15 total cost estimate of GBP160 
million. 
 
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. As outlined previously, 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 over GBP50 
million in the first three and a half 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. As outlined previously, 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 in its strategic decision making. 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. UU is one of only seven FTSE 100 
companies (and the only water company) to hold both accolades. 
 
Our strong, year round, operational focus on leakage and the implementation of 
a range of initiatives, such as active pressure management, enabled us to again 
beat our leakage target for 2012/13. Our aim is meet our leakage target each 
year. 
 
Environmental performance is a high priority for UU and we are pleased to again 
deliver a strong performance as assessed through Ofwat's published KPIs for 
2012/13. Across Ofwat's five 'Environmental Impact' KPIs, UU's performance was 
above average, with three areas assessed as 'Green', two as 'Amber' and no 
areas assessed as 'Red', on the traffic light reporting matrix. 
 
Our GBP100 million+ project in Preston, which is designed to improve river and 
bathing quality, is nearing completion. The project involved 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 Fylde Coast bathing waters and the 
Ribble Estuary. 
 
We are committed to reducing our carbon footprint and increasing our generation 
of renewable energy. We remain on track to meet our plan target of a 21% 
reduction in carbon emissions by 2015 (measured from a 2005/06 baseline). We 
have consistently generated around 100 GWh of renewable electricity annually 
for the past four years, principally from sludge processing, and expect this to 
increase with the completion of our GBP100 million+ recycling and energy plant at 
our Davyhulme wastewater site in 2014. 
 
We continue to be successful in attracting and retaining people and have 
continued to expand our apprentice and graduate programmes, having recruited a 
further 24 graduates and 32 apprentices in 2013/14. We remain firmly focussed 
on our health and safety improvement programme, as we strive for continuous 
improvement. 
 
Key performance indicators: 
 
* Leakage - UU met its economic level of leakage rolling target for the seventh 
consecutive year in 2012/13. The aim is to meet our regulatory leakage target 
each year. 
 
* Environmental performance - The Environment Agency's 2012/13 assessment, 
covering a broad range of operational metrics, is due to be published shortly. 
UU's good performance on Ofwat's KPIs, within the `Environmental Impact' 
category, should positively impact the EA's overall assessment. For the EA's 
2011/12 assessment, based on the balance of 'Green', 'Amber' and 'Red' 
categories, UU would rank third out of the ten water and sewerage companies. 
The medium-term goal is to be 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 recently retained its 'World 
Class' rating and aims to retain this rating each year. 
 
FINANCIAL PERFORMANCE 
 
Revenue 
 
UU has delivered a good set of financial results for the six months ended 30 
September 2013. Revenue increased by GBP30 million to GBP853 million, principally 
reflecting a 4.0% nominal (1.0% real price increase plus 3.0% RPI inflation) 
allowed regulated price increase. 
 
Operating profit 
 
Underlying operating profit increased by 9% to GBP343 million, primarily as a 
result of an increase in revenue and benefiting from tight cost control with 
total operating expenses up GBP3 million, representing an increase of less than 
1%. Reported operating profit increased by 9% to GBP342 million. 
 
Investment income and finance expense 
 
The underlying net finance expense of GBP128 million was GBP2 million higher than 
the first half of last year, reflecting an increase in index-linked debt. The 
indexation of the principal on index-linked debt amounted to a net charge in 
the income statement of GBP45 million, compared with a net charge of GBP43 million 
in the first half of last year. The group had approximately GBP2.9 billion of 
index-linked debt as at 30 September 2013. The group's average underlying 
interest rate of 4.8% was slightly lower than the rate of 5.0% for the 
corresponding prior year period, mainly reflecting a reduction in cash. 
 
Reported investment income and finance expense of GBP7 million was significantly 
lower than the GBP175 million expense in the first half of 2012/13. This GBP168 
million reduction principally reflects a change in the fair value gains and 
losses on debt and derivative instruments, from a GBP49 million loss in the first 
half of last year to a GBP100 million gain in the first half of 2013/14. The GBP100 
million fair value gain in the half year is largely due to gains on the 
regulatory swap portfolio, resulting from a significant increase 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 GBP216 million, GBP27 million higher than the 
corresponding period last year, due to the GBP29 million increase in underlying 
operating profit slightly offset by the GBP2 million increase in underlying net 
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 GBP196 million to GBP335 million. 
 
Taxation 
 
The current taxation charge is GBP49 million in the half year, compared with GBP33 
million in the corresponding period last year. In addition, there was a current 
taxation credit of GBP122 million relating to recently agreed matters with HMRC 
in relation to prior years. We expect this to result in a one-off cash taxation 
inflow of around GBP75 million to be received in this or the next financial year. 
 
The group has a deferred taxation charge of GBP23 million in the first half of 
2013/14, compared with a charge of GBP3 million in the first half of 2012/13. The 
group has recognised a deferred taxation credit of GBP159 million in the first 
half of 2013/14 which relates to the 3% staged reduction in the mainstream rate 
of corporation taxation, substantively enacted on 2 July 2013, to reduce 
taxation to 20% by 2015/16. A deferred taxation credit of GBP53m relating to a 
similar 1% reduction in the mainstream rate of corporation taxation was 
included in the first half of 2012/13. The group also recognised a deferred 
taxation credit of GBP3 million relating to recently agreed matters in relation 
to prior years. 
 
An overall taxation credit of GBP212 million has been recognised for the six 
months ended 30 September 2013. Excluding the deferred taxation impact of the 
future reduction in the corporation taxation rate and the adjustments relating 
to recently agreed matters in relation to prior years, the total taxation 
charge would have been GBP72 million or 21% compared with a GBP35 million charge or 
25% in the first half of last year. This reduction in total taxation rate is 
due to the decrease in the mainstream rate of corporation taxation from 24% for 
2012/13 to the current rate of 23%, together with the period-on-period movement 
in taxation disallowable items. 
 
The group made cash taxation payments during the half year of GBP27 million. This 
was higher than the group's net taxation payment of GBP17 million in the first 
half of last year, primarily due to the high levels of pension contributions 
relating to the previous year. 
 
Profit after taxation 
 
Underlying profit after taxation of GBP168 million was GBP27 million higher than 
the first half of last year, principally reflecting the increase in underlying 
profit before taxation. Reported profit after taxation was GBP547 million, 
compared with GBP157 million in the first half of last year, impacted by the GBP149 
million improvement in fair value gains on debt and derivative instruments and 
the GBP194 million increase in the net taxation credit between the two periods. 
 
Earnings per share 
 
Underlying earnings per share increased from 20.8 pence to 24.7 pence. This 
underlying measure is derived from underlying profit after taxation. This 
includes the adjustments for the deferred taxation credits in both the first 
half of 2013/14 and 2012/13, associated with the reductions in the corporation 
taxation rate and an adjustment for the taxation credit arising from agreement 
of prior years' taxation matters in the first half of 2013/14. Basic earnings 
per share increased from 23.0 pence to 80.2 pence. 
 
Dividend per share 
 
The board has declared an interim dividend of 12.01 pence per ordinary share in 
respect of the six months ended 30 September 2013. This is an increase of 5.0%, 
compared with the dividend relating to the first half of last 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 3.0% is based on the RPI 
element included within the allowed regulated price increase for the 2013/14 
financial year (i.e. the movement in RPI between November 2011 and November 
2012). 
 
The interim dividend is expected to be paid on 3 February 2014 to shareholders 
on the register at the close of business on 20 December 2013. The ex-dividend 
date is 18 December 2013. 
 
Cash flow 
 
Net cash generated from continuing operating activities for the six months 
ended 30 September 2013 was GBP383 million, compared with GBP265 million in the 
first half of last year. This mainly reflected an improvement in working 
capital cash flows, impacted by the reduction in the total pension contribution 
payments between the two periods, as well as an increase in operating profit. 
The group's net capital expenditure was GBP335 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 (IFRS). 
 
Net debt including derivatives at 30 September 2013 was GBP5,485 million, 
compared with GBP5,451 million at 31 March 2013. This slight increase reflects 
expenditure on the regulatory capital expenditure programmes and payments of 
dividends, interest and taxation, alongside an increase in the principal of our 
index-linked debt, largely offset by operating cash flows and fair value gains 
on our debt and derivative instruments. 
 
Debt financing and interest rate management 
 
Gearing (measured as group net debt divided by UUW's regulatory capital value 
adjusted for actual capital expenditure) decreased marginally to 59% at 30 
September 2013, compared with 60% at 31 March 2013, remaining comfortably 
within Ofwat's 55% to 65% assumed gearing range. The group's pension accounting 
position has moved to a deficit of GBP184 million at 30 September 2013, on an 
IFRS basis, compared with a small pension surplus of GBP15 million as at 31 March 
2013. Taking account of the group's pension deficit, and treating it as debt, 
gearing would be 61%. 
 
At 30 September 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. Standard & 
Poor's currently have both the group's ratings on positive outlook, citing 
improving financial metrics and operational performance. 
 
Cash and short-term deposits at 30 September 2013 amounted to GBP53 million and, 
taken together with medium-term committed bank facilities, 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 provides a natural hedge to 
assets and earnings. At 30 September 2013, approximately 53% 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 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 2009 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 help mitigate the risk of the group being materially misaligned 
with 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 30 September 2013 was GBP273 million based on 
cash, short-term deposits and medium-term committed bank facilities, net of 
short-term debt. 
 
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 30 September 2013, the group had an IAS 19 net retirement benefit, or 
pension, deficit of GBP184 million, compared with a net pension surplus of GBP15 
million at 31 March 2013. This GBP199 million adverse movement principally 
reflects the movement of market rates during the period, particularly 
influenced by the significant reduction in corporate credit spreads. In 
contrast, the scheme specific funding basis does not suffer from volatility due 
to credit spread movements as it uses a conservative, fixed credit spread 
assumption. Therefore, the recent credit spread movements have not had a 
material impact on the scheme specific funding and the level of deficit repair 
contributions. 
 
The triennial actuarial valuations of the group's defined benefit pension 
schemes were carried out as at 31 March 2013 and the overall funding position 
has improved since March 2010. Following the de-risking measures we have 
implemented over recent years, our pension funding position remains well placed 
and in line with our expectations. There has been no material change to the 
scheduled cash contributions as assessed at the previous valuations in 2010. 
The group has already completed early all scheduled deficit repair payments 
through to March 2015.

surplus") of these condensed consolidated financial statements.

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 the group's objectives and the prioritised 
implementation of controls and mitigation to manage the exposure and build 
resilience. 
 
The audit 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. 
 
The group's anticipated principal risks and uncertainties over the second half 
of the financial year and beyond remain as stated in its 2013 Annual Report and 
Financial Statements, with the additional development of elevated political and 
public focus in relation to the cost of utility bills to household customers as 
explained in the paragraph below.  The principal risks and uncertainties were 
set out in full on pages 32-37 of the 2013 Annual Report and Financial 
Statements, namely (a) government market reform agenda; (b) future price limits 
and the price control review 2014; (c) failure to comply with applicable law or 
regulations; (d) material litigation; (e) pension deficit risk; (f) 
counterparty risk; (g) customer service risk; (h) bad debt risk; (i) 
operational service risk; (j) capital delivery risk; (k) secure supply of safe 
clean drinking water risk; and (l) significant and catastrophic events. 
 
There is currently an elevated political and public focus on the cost to 
households of bills, especially in relation to certain utilities including the 
regulated water industry.  The Secretary of State for Environment, Food and 
Rural Affairs has recently written to industry CEOs supporting the work being 
done by Ofwat and the industry to ensure a fair deal for customers and 
stressing the need to keep bills for customers as low as possible, while 
ensuring that low-cost investment in the sector continues.  It is unclear 
whether the broader political and public focus on utilities will ultimately 
impact Government policy, legislation or regulatory outcomes affecting the 
sector. 
 
There has been no change to the nature of related party transactions in the 
first six months of the financial year which has materially affected the 
financial position or performance of UU.

NOTES 
 
1. Basis of preparation and accounting policies 
 
The condensed consolidated financial statements for the six months ended 30 
September 2013 have been prepared in accordance with the Disclosure and 
Transparency Rules of the Financial Services Authority and International 
Accounting Standard 34 'Interim Financial Reporting' (IAS 34). 
 
The accounting policies, presentation and methods of computation are consistent 
with those set out in the audited consolidated financial statements of United 
Utilities Group PLC for the year ended 31 March 2013, with the exception of the 
adoptions detailed below, and are prepared in accordance with International 
Financial Reporting Standards (IFRSs) as adopted by the European Union (EU), 
including International Accounting Standards (IAS) and Interpretations issued 
by the International Financial Reporting Interpretations Committee (IFRIC). 
 
The adoption of the following standards and interpretations, at 1 April 2013, 
has had no material impact on the group's financial statements. 
 
IAS 19 (Revised) 'Employee Benefits' 
 
The impact of the changes in this standard is to replace interest cost and 
expected return on plan assets with a net interest amount that is calculated by 
applying the discount rate to the net defined benefit (obligations)/surplus. In 
addition, the standard clarifies that administration costs relating to the 
administration of benefits should be recognised as an employee benefits expense 
through the income statement, rather than as a deduction from the return on 
plan assets which was previously recognised through other comprehensive income. 
The standard's application is retrospective and hence requires the restatement 
of the comparative periods ended 30 September 2012 and 31 March 2013. 
 
The impact in the period to 30 September 2013 has been an increase in employee 
benefit expense of GBP1.2 million (30 September 2012: GBP1.0 million, 31 March 
2013: GBP2.9 million), a decrease in finance expense of GBPnil million (30 
September 2012: GBP4.8 million, 31 March 2013: GBP10.0 million) and an offsetting 
gain to actuarial gains and losses within other comprehensive income of GBP1.2 
million (30 September 2012: GBP3.8 million loss, 31 March 2013: GBP7.1 million 
loss). These amendments have had no overall impact on the retirement benefit 
(obligations)/surplus in the statement of financial position. 
 
The impact on taxation in the period to 30 September 2013 has been a deferred 
taxation credit of GBP0.2 million (30 September 2012: GBP0.9 million charge, 31 
March 2013: GBP1.6 million charge) and an offsetting charge to actuarial gains 
and losses within other comprehensive income of GBP0.2 million (30 September 
2012: GBP0.9 million credit, 31 March 2013: GBP1.6 million credit). 
 
IFRS 13 'Fair Value Measurement' 
 
The standard provides guidance on the measurement of fair value where required 
by existing accounting standards. The standard's application is prospective in 
line with the transitional provisions of the standard. The impact on the period 
to 30 September 2013 has been a GBP0.3 million credit to finance expense and a 
corresponding reduction in non-current derivative liabilities, due to the 
inclusion of the group's own credit risk in measuring the fair value of its 
liabilities. 
 
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 2013 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 group 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 also considered the primary legal duty of United Utilities Water 
PLC's economic regulator, to ensure that the companies can finance their 
functions. 
 
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, regulatory capital 
expenditure and RCV gearing 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 to its interest rate management strategy in the year ended 31 March 
2012, the group has continued to extend the fixing of interest rates out to a 
ten 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 GBP127.5 million 
(30 September 2012: GBP126.0 million, 31 March 2013: GBP252.8 million) is derived 
as shown in the table below.

The current taxation charge is GBP48.7 million for the period ended 30 September 
2013 representing a current taxation effective rate of 15 per cent compared 
with 23 per cent in the corresponding period last year and 26 per cent for the 
year ended 31 March 2013. The reduction is principally due to fair value 
movements which give rise to a corresponding current period deferred taxation 
charge. In addition, there is a current taxation credit of GBP122.0 million, and 
an associated deferred tax credit of GBP3.0 million relating to recently agreed 
matters in relation to prior years. 
 
The deferred taxation credits for the periods ended 30 September 2013, 30 
September 2012 and 31 March 2013 include a credit of GBP158.6 million, GBP52.8 
million and GBP53.0 million respectively to reflect the staged reductions in the 
mainstream rate of corporation tax from 24 per cent in the year ended 31 March 
2013 to 20 per cent effective from 1 April 2015.

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 for the period ended 30 
September 2013 relates primarily to the release of accrued costs of disposal in 
respect of certain elements of the group's non-regulated disposal programme. 
 
7. 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 
 
Six months ended 30 September 2013                          681.9       682.9 
 
Six months ended 30 September 2012                          681.8       682.6 
 
Year ended 31 March 2013                                    681.9       682.8 
 
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 periods are 
as follows:

Under the prescribed IAS19 basis, pension scheme liabilities are calculated 
based on current accrued benefits. These are then projected forwards and 
inflated by forecast RPI for the relevant time period based on current member 
mortality assumptions. These projected cash flows are then discounted by a AA 
corporate bond rate which comprises both an underlying interest rate and a 
credit spread. 
 
In de-risking our pension scheme, we have largely hedged: (1) the underlying 
interest rate through external market swaps, the value of which is included in 
scheme assets; and (2) the forecast RPI through the Inflation Funding Mechanism 
(IFM), which is treated as an additional schedule of deficit contributions and 
is not included in the value of scheme assets until contributions are actually 
paid into the pension scheme. 
 
As a consequence the reported statement of financial position under IAS19 
remains volatile due to changes in: (1) credit spread (because hedging credit 
spreads over long durations is difficult); (2) inflation (because inflation is 
hedged via the IFM and is treated as a schedule of contributions, not as a 
scheme asset); and to a lesser extent (3) mortality (it was decided not to 
hedge this risk due to its lower volatility in the short term). 
 
In contrast the scheme specific funding basis (which forms the basis for 
deficit repair contributions) is unlikely to suffer from volatility due to 
credit spread (as it uses a conservative, fixed credit spread assumption) or 
inflation (as it includes the value of the IFM). 
 
In the IAS19 assessment of financial position at 30 September 2013, although 
the discount rate has fallen by 0.2% this masks a rise in underlying interest 
rates offset by a credit spread reduction of 0.4%. This credit spread reduction 
results in substantially all of the reported GBP199.0m deterioration. During the 
six months ended 30 September 2013, there has not been any material change in 
the scheme specific funding basis and therefore the level of deficit repair 
contributions. 
 
The closing (obligations)/surplus at each reporting date are analysed as

INDEPENDENT REVIEW REPORT TO UNITED UTILITIES GROUP PLC 
 
Introduction 
 
We have been engaged by the company to review the condensed set of financial 
statements in the half-yearly financial report for the six months ended 30 
September 2013 which comprises the consolidated income statement, the 
consolidated statement of comprehensive income, the consolidated statement of 
financial position, the consolidated statement of changes in equity, he 
consolidated statement of cash flows and the related explanatory notes. We have 
read the other information contained in the half-yearly financial report and 
considered whether it contains any apparent misstatements or material 
inconsistencies with the information in the condensed set of financial 
statements. 
 
This report is made solely to the company in accordance with the terms of our 
engagement to assist the company in meeting the requirements of the Disclosure 
and Transparency Rules ("the DTR") of the UK's Financial Conduct Authority 
("the UK FCA"). Our review has been undertaken so that we might state to the 
company those matters we are required to state to it in this report and for no 
other purpose. To the fullest extent permitted by law, we do not accept or 
assume responsibility to anyone other than the company for our review work, for 
this report, or for the conclusions we have reached. 
 
Directors' responsibilities 
 
The half-yearly financial report is the responsibility of, and has been 
approved by, the directors. The directors are responsible for preparing the 
half-yearly financial report in accordance with the DTR of the UK FCA. 
 
As disclosed in note 1, annual financial statements of the group are prepared 
in accordance with IFRSs as adopted by the EU. The condensed set of financial 
statements included in this half-yearly financial report has been prepared in 
accordance with IAS 34 Interim Financial Reporting as adopted by the EU. 
 
Our responsibility 
 
Our responsibility is to express to the company a conclusion on the condensed 
set of financial statements in the half-yearly financial report based on our 
review. 
 
Scope of review 
 
We conducted our review in accordance with International Standard on Review 
Engagements (UK and Ireland) 2410 Review of Interim Financial Information 
Performed by the Independent Auditor of the Entity issued by the Auditing 
Practices Board for use in the UK. A review of interim financial information 
consists of making enquiries, primarily of persons responsible for financial 
and accounting matters, and applying analytical and other review procedures. A 
review is substantially less in scope than an audit conducted in accordance 
with International Standards on Auditing (UK and Ireland) and consequently does 
not enable us to obtain assurance that we would become aware of all significant 
matters that might be identified in an audit. Accordingly, we do not express an 
audit opinion. 
 
Conclusion 
 
Based on our review, nothing has come to our attention that causes us to 
believe that the condensed set of financial statements in the half-yearly 
financial report for the six months ended 30 September 2013 is not prepared, in 
all material respects, in accordance with IAS 34 as adopted by the EU and the 
DTR of the UK FCA.
