For Immediate Release                                                  17th October 2002


National Grid Group plc and Lattice Group plc
SEC Authorisation Received

National  Grid Group plc  (“National  Grid”)  and  Lattice  Group plc  (“Lattice”)  announce  that  yesterday  National  Grid  received
authorisation  from the US  Securities  and  Exchange  Commission,  under the Public  Utilities  Holding  Company Act of 1935,  for its
proposed  financing  arrangements  in respect of its merger with Lattice to form  National  Grid Transco (the  “Merger”).  This was the
final regulatory approval outstanding in the US.

The Merger  therefore only remains subject to the sanction of the Lattice Scheme of Arrangement  (the “Scheme”) by the High Court,  the
Scheme  becoming  effective and admission of the New National Grid Transco Shares to the Official List of the UK Listing  Authority and
to trading on the London Stock Exchange.  All other conditions to the Merger have now been waived or satisfied.

As previously announced,  the hearing of the petition to sanction the Scheme has been arranged for today.  Accordingly,  subject to the
High Court sanctioning the Scheme at that hearing, National Grid and Lattice expect:
-        the Lattice Scheme Record Time to be 6.00pm on 18 October 2002, the last day of dealings in Lattice Shares;
-        the Lattice Scheme Effective Date to be 21 October 2002, and the following events to take place on that date:
-        completion of the Merger;
-        the change in National Grid’s name to National Grid Transco plc;
-        admission of the New National  Grid Transco  Shares to the  Official  List of the UK Listing  Authority  and to trading on the
         London Stock Exchange;
-        commencement of dealings in New National Grid Transco Shares on the London Stock Exchange; and
-        crediting of New National Grid Transco Shares to the relevant CREST accounts; and
-        the New National  Grid Transco  Share  certificates  to be dispatched  to the relevant  Lattice  Shareholders  no later than 4
         November 2002.

Terms used in this  announcement  shall  have the same  meaning as in the  respective  Circulars  circulated  by  National  Grid to its
shareholders and by Lattice to its shareholders, in both cases dated 14 June 2002.
