LONDON—U. K. business investment fell slightly year-over-year in the three months running up to June's vote on the country's European Union membership, official data showed Friday, signaling that the referendum uncertainty may have weighed on the country's business climate.

Business investment decreased by 0.8% in the April-June period compared with the same period a year earlier, the Office for National Statistics said, and stood at £ 43.9 billion ($58.05 billion). Compared with the first quarter, it grew by 0.5%.

The ONS also confirmed its earlier estimates of the gross domestic product growth figures for the same period. The U.K. economy grew by 0.6% quarter-on-quarter, the data showed, and by 2.2% from the same period last year. In annualized terms, the U.K. economy grew by 2.4%.

While the reporting period included the national vote on EU membership, whose shock result has since brought the pound down by some 11% against the dollar, the ONS said there was currently "very little" anecdotal evidence that the referendum had any impact on the pace of economic growth in that time.
