The Company has been informed that Northumbrian Water Share Scheme Trustees
Limited (the Trustee of the NWG Long Term Incentive Plan) has today, 13 February

exercise of LTIP awards by people who are neither directors of the Company nor
persons discharging managerial responsibility ("PDMR"). The disposal of these

Following this reduction, the Trustee holds 793,064 shares, representing 0.153%
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.


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