                           Dealing by employee trust


The Company has been informed that Northumbrian Water Share Scheme Trustees
Limited (the Trustee of the NWG Long Term Incentive Plan) has today, 9 February
2007, sold 5,906 ordinary 10 pence shares as a result of the exercise of an LTIP
award by someone who is neither a director of the Company nor a person
discharging managerial responsibility ("PDMR"). The sale of these shares is
pursuant to a conditional award of shares made on 27 January 2004.


Following this reduction, the Trustee holds 810,988 shares, representing 0.156%
of the Company's issued share capital.


The 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.
