The Company was informed on 2 March 2007 that Northumbrian Water Share Scheme
Trustees Limited, as Trustee of the NWG Long Term Incentive Plan (the "LTIP
Trustee") sold or transferred 18,343 ordinary 10 pence shares on 2 March 2007 as
a result of the exercise of LTIP awards by someone who is neither a director of
the Company nor a person discharging managerial responsibility ("PDMR"). The
disposal of these shares is pursuant to a conditional award of shares made on 27
January 2004.


Following this disposal, the LTIP Trustee holds 745,765 shares, representing
0.144% of the Company's issued share capital.


The LTIP Trustee holds these shares in order to satisfy awards made under the
Company's LTIP, and so John Cuthbert and Chris Green, as executive directors of
the Company, and Ceri Jones and Graham Neave, as PDMRs of the Company, are
potential beneficiaries of these shares.


This announcement is made in accordance with the requirements of DTR 3.1.4 R(1).
