INTERIM MANAGEMENT STATEMENT

Pennon Group Plc today reports in respect of trading up to Friday, 8 February
2008.  Group turnover, operating profit and profit before tax for the period
were all in line with management expectations.

South West Water is now in the third year of the K4 period (2005 - 2010) and
remains on target to meet the current regulatory contract.  As part of the K5
planning process, a major customer consultation exercise was launched in
November last year.  The company published its 25 year Strategic Direction
Statement in December.

Viridor remains confident of delivering continued full year growth in operating
profit before intangibles.  On 5 December 2007, Grosvenor Waste Management, a
leading UK materials recycling company, was acquired for a cash consideration of
£79.5m (plus debt of £1.5m).

Further details can be found on the Company's website, www.pennon-group.co.uk

Pennon intends to announce its Preliminary Results on Thursday, 5 June 2008.
