Voting Rights and Capital update


National Grid has been notified that 37,686 shares held in Treasury were today
transferred to share scheme participants. Following this change, National Grid
plc's registered capital consists of 2,605,885,957 ordinary shares, of which
13,133,370 have been purchased in the market and registered as Treasury Shares;
leaving a balance of 2,592,752,587 shares with voting rights.

The figure of 2,592,752,587 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).
