National Grid plc (National Grid)

Voting Rights and Capital update


National Grid was notified late yesterday (2 January) that 6,203 shares held in
Treasury were transferred to share scheme participants. A further 14,458 shares
have today been transferred from Treasury to share scheme participants.
Following these changes, National Grid plc's registered capital consists of
2,581,913,516 ordinary shares, of which 32,347,308 have been purchased in the
market and registered as Treasury Shares; leaving a balance of 2,549,566,208
shares with voting rights.

The figure of 2,549,566,208 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 transfer to Treasury, or cancellation,
of the shares involved (and any earlier repurchases which remain to be
registered).
