National Grid plc (National Grid)


Voting Rights and Capital update


National Grid was notified late yesterday that 418,493 shares held in Treasury
were transferred to share scheme participants and further notified today that
another 8,087 shares held in Treasury had been transferred to share scheme
participants. Following these changes, National Grid plc's registered capital
consists of 2,611,563,094 ordinary shares, of which 13,171,056 have been
purchased in the market and registered as Treasury Shares; leaving a balance of
2,598,392,038 shares with voting rights.

The figure of 2,598,392,038 may be used by shareholders as the denominator for
the calculations by which they will determine if they are required to notify
their interest in, or a change to their interest in, National Grid plc under the
FSA's Disclosure and Transparency Rules.

Note: This notification confirms actual capital as recorded on the register at
the above date, allowing for changes recorded since the last notification.
National Grid is currently undertaking a share repurchase programme.  Where
repurchases are made, separate covering announcements will, as required,
identify numbers being repurchased and the supporting details indicate resultant
share capital after market settlement and cancellation, or transfer to Treasury,
of the shares involved (and any earlier repurchases which remain to be
registered).
