Interim Management Statement

SEVERN TRENT PLC ("THE COMPANY")

INTERIM MANAGEMENT STATEMENT

29 January 2008

Severn Trent today publishes its interim management statement for the period
from 1 October 2007 to date.

The Board can confirm that trading has been in line with its expectations, with
no material trading events or transactions occurring during the period.

Our outlook also remains consistent with that given in our interim results
announcement on 27 November 2007:

The Company is on track to meet the Ofwat determination for operating costs for
the full year 2007/08.

The capital programme is proceeding according to plan and we expect that the
previously announced efficiencies of around 6% over the Ofwat determination
continue to be deliverable over the remaining AMP4 period.

Our focus on continuous improvement is delivering tangible results in our
improved performance on leakage management, with a significant reduction in
levels of leakage in the period to date compared to the previous financial
year. We remain on track to achieve the Ofwat annual target for the year ending
31 March 2008.

Estimates of the gross economic costs associated with the flooding remain
unchanged at £25-£35 million, with insurance recovery estimates unchanged at £
10-£20 million.

Severn Trent will publish a pre-close period trading statement on 2 April 2008
and announce its preliminary full year results on 5 June 2008.
