The company remains firmly on track to deliver its2010-15 regulatory outperformance targets and has delivered further customerservice improvements through strong operational focus. Revenue is expected to be higher than the first half of last year, reflectingthe regulated price increase for 2013/14. As indicated previously, this revenueincrease is expected to be slightly below the allowed regulated price rise,principally reflecting the on-going impact of a tough economic climate onvolumes. Underlying operating profit for the first half of 2013/14 isanticipated to be moderately higher than the first half of 2012/13, as thecompany continues to tightly manage its cost base. United Utilities has made good progress on its regulatory capital investmentprogramme and, as planned, expects to invest around £800 million in 2013/14,including infrastructure renewals expenditure. This substantial investmenthelps to maintain and improve services for customers, delivers furtherenvironmental benefits and provides a significant contribution to the regionaleconomy.

Group net debt at 30 September2013 is expected to be slightly higher than the position at 31 March 2013.
