Director/PDMR Shareholding

Transfer of shares by the Trustee of the Severn Trent Plc Employee Share
Ownership Trust

The Company has been advised by the Trustee of the Severn Trent Plc Employee
Share Ownership Trust that, on 18 June 2008, 155,453 Ordinary Shares of 9717/
19p each in the Company were transferred for nil consideration to participants
in the Long Term Incentive Plan 2005 (including Persons Discharging Managerial
Responsibilities (PDMRs) of the Company as indicated below) pursuant to awards
made under that plan in 2005.

PDMRs are potential beneficiaries under the Trust and, therefore, (except as
disclosed below) their interests in those shares ceased on such transfer.
