PART 2 - NOTIFICATION OF CHANGES TO DIRECTORS' INTERESTS IN SHARES


LATTICE GROUP ALL EMPLOYEE SHARE OWNERSHIP PLAN (AESOP)

The Company was notified on 25 October 2002 that the trustees of the AESOP have
awarded National Grid Transco plc ordinary shares of 10p each to eligible
Executive Directors and other former Lattice Group employees under the Free
Shares element of the AESOP at a price of £4.7142p per share. Awards represent
performance against targets for the six months ended 30 September 2002 and have
been capped at a maximum value of £1,500 per participant.

Shares must be held in trust for a minimum of five years to be fully tax free,
unless the participant leaves for any of the special reasons defined in the
Rules.

Details of awards to Executive Directors are as follows:

                         as at 24 October 2002     awarded on 25          Shareholding

A total of 2,005,941 National Grid Transco plc shares were allocated to
participants under the AESOP Free Shares awards on 25 October 2002. The
Executive Directors ceased to have a potential interest in these shares, other
than those awarded to them as set out above. Accordingly, they now have a
potential interest in 680,913 shares in the Company still held by the trustee of
the AESOP.

Further, on 25 October 2002, Mourant & Co. Trustees Ltd as trustee of the
Lattice Group Long Term Incentive Scheme transferred a total of 3,160,179 shares
in the Company to participants. Accordingly, Steve Lucas and John Wybrew, as
with other employees of the former Lattice Group, ceased to have a potential
interest in these shares and now have a potential interest in 767,665 National
Grid Transco plc shares still held by Mourant & Co. Trustees Ltd.
