                           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, 5 February
2007, sold 14,215 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 Trust holds 833,095 shares, representing 0.161% of
the Company's issued share capital.

The Trust 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 held in the Trust.
