The total number of shares in issue as at 3 October 2005 is 3,659,741,111.

Following this release, the LTIS trust, in which the executive directors and
other PDMRs along with other Centrica group employees have a potential interest,
holds no shares.

* The performance condition for the LTIS is linked to the Company's total
shareholder return (TSR) relative to the returns of its FTSE 100 comparator
group. The maximum award only vests if the Company's TSR over the performance
period is ranked in 25th position or above of the 100 companies in the LTIS
comparator group.

For the award made in 2000, at the conclusion of the performance period on 1
October 2003, the Company was ranked in fortieth position in the LTIS comparator
group and, accordingly, 75% of the award was transferable at the end of the
required two-year retention period.
