Interim Management Statement

26 January 2010 Severn Trent Plc Interim Management Statement for the period 1 October 2009 to 25 January 2010 The Board of Severn Trent Plc confirms that trading has been in line with its expectations, with no material trading events or transactions occurring during the period from 1 October 2009 to 25 January 2010. The decline in consumption previously noted at Severn Trent Water Limited across the measured income base, which was driven principally by non-household customers, has stabilised. It is estimated that the year-on-year impact on revenues will now be around £5 to £10 million in the current financial year, from the £15 to £20 million previously indicated. The current bad debt level has remained at around 2.3% of turnover, the level at which we exited last financial year and the level reported for the first half of the current financial year. We continue to monitor future developments closely. Operating expenditure and capital expenditure continues to be in line with the Board's expectations for the year and AMP4 period. It is expected that net capital expenditure (UK GAAP after deducting grants and contributions) for the year will be around £610 to £630 million, in line with expectations. The level of net infrastructure renewals expenditure included in this figure (charged to the income statement under IFRS) is anticipated to be around £100 to £110 million. The recent extreme weather has had some impact on operations, with the prolonged period of freezing temperatures causing an increase in leakage above normal levels for the winter. Severn Trent Water has brought in additional resources and is working to bring leakage rates back down as rapidly as possible. It is too early to evaluate the impact on annual leakage performance, which will be assessed post March year end. The additional cost of repairing these leaks is not material in the context of total annual operating expenditure. Severn Trent Plc announced on 19 January 2010 that its subsidiary, Severn Trent Water, had accepted Ofwat's final set of proposals for the period 2010-2015 (the "Final Determination"). Severn Trent Plc will announce its preliminary full year results for the financial year ending 31 March 2010 on 28 May 2010.
