Directorate Change

CHANGES TO BOARDS OF SEVERN TRENT PLC AND SEVERN TRENT WATER LIMITED

Severn Trent Plc announces today that Colin Matthews has retired from the
Boards of Severn Trent Plc and Severn Trent Water Limited and that Tony Wray,
Managing Director of Severn Trent Water Limited, has taken over from Colin
Matthews as Chief Executive.

This completes the process Severn Trent announced in June whereby the roles of
Chief Executive and Managing Director would be combined this year with Tony
Wray replacing Colin Matthews.

The Chairman of Severn Trent Plc, Sir John Egan, said "Colin has made an
outstanding contribution during a period of substantial change.

"We have completed the transformation of the Group with the demerger of Biffa,
the £575 million special dividend to shareholders and the sale of other
businesses such as ST Property and ST US Laboratories. We have also outlined
detailed plans for fundamental improvement across all areas of our Severn Trent
Water business based on our 20 critical success factors against which we will
measure our performance and progress.

"His leadership has been crucial to the successful restructuring of Severn
Trent. Colin has played a key role in laying firm foundations on which Tony can
build for Severn Trent's future success."

Mr Matthews said he was fortunate and proud to have been Chief Executive of
Severn Trent during a significant period in its history.

"The renewal and reorganisation of Severn Trent has been a complex and
fascinating journey that has, importantly, created value for shareholders and
positioned the company for an exciting future," Mr Matthews said.

"I have been supported by excellent people both in the businesses we have
divested as well as in those we have retained. I would like to thank all of
them for their commitment and support and I wish Tony the very best in taking
Severn Trent forward."

Severn Trent Plc also announces that with effect from today the following
Directors have been appointed as Executive Directors of Severn Trent Plc and
Severn Trent Water Limited:

Tony Ballance (Director, Regulation and Competition)

Martin Kane (Director, Customer Relations)

Andy Smith (Director, Water Services)

Sir John Egan said "These appointments reinforce the board's commitment to the
successful transformation of the Group into a focused water company. In
addition, the board is actively seeking to recruit a further non-executive
director to the Boards of Severn Trent Plc and Severn Trent Water Limited to
complement the existing skills base. We will update the market when a suitable
candidate has been appointed."
