The Company has been informed that Northumbrian Water Share Scheme Trustees
Limited (the "Trustee") of the NWG Long Term Incentive Plan (the "Plan") has
today, 29 January 2007, transferred ordinary 10 pence shares to directors of the
Company at nil cost pursuant to the rules of the Plan. The transfer of shares is
pursuant to a conditional award of shares made on 27 January 2004.


John Cuthbert, a director, acquired 61,737 shares under the LTIP, representing
0.012% of the Company's issued capital. Of these, 25,387 shares (0.005%) were
sold at £2.955 per share to meet tax liabilities. A further 10,000 shares were
transferred to family members over the age of 18 and the balance of 26,350
shares was transferred to Mrs L E Cuthbert. Mr Cuthbert's beneficial holding in
the Company is now 129,915 shares, representing 0.025% of the Company's issued
share capital.


Chris Green, a director, acquired 40,833 shares under the LTIP, representing
0.008% of the Company's issued capital. Of these, 16,791 shares (0.003%) were
sold at £2.955 per share to meet tax liabilities, and the balance of 24,042
shares was transferred to Mrs G F Green. Mr Green's beneficial holding in the
Company is now 92,607 shares, representing 0.018% of the Company's issued share
capital.


The Trustee has also transferred at nil cost 78,654 shares to participants, not
being directors of the Company nor persons discharging managerial responsibility
("PDMRs"), under the Plan. Of these, 9,820 shares have been sold to meet tax
liabilities.


Following this reduction, the Trust holds 865,444 shares, representing 0.167% 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, are potential beneficiaries
of these shares held in the Trust.


This notification is made in accordance with DTR3.1.4R(1).
