in the market and registered as treasury shares, leaving a balance of
2,550,132,419 shares with voting rights.

The figure of 2,550,132,419 may be used by shareholders as the denominator for
the calculations by which they will determine if they are required to notify
their interests in, or a change to their interest in, National Grid plc under
the Disclosure and Transparency Rules.

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).
