Centrica plc
Annual Long Term Incentive Scheme Allocations

Centrica announces that on 1 April 2005, conditional allocations of ordinary
shares in Centrica plc were made by the trustee of the Centrica Long Term
Incentive Scheme (LTIS) to a number of employees, including the following
Executive Directors:


Executive director                 Number of shares
                              in conditional allocation
------------------------------------------------------------
Phillip Bentley                        165,646
------------------------------------------------------------
Mark Clare                             164,006
------------------------------------------------------------
Sir Roy Gardner                        292,258
------------------------------------------------------------
Jake Ulrich                            168,926
------------------------------------------------------------


The percentage of the allocation eventually to vest is dependent on the
satisfaction of performance criteria over a three-year performance period
commencing on 1 April 2005. The performance criteria are based on the Company's
total shareholder return (TSR) against that of the companies comprising the FTSE
100 at the start of the performance period (the Comparator Group).(1)

The base price from which performance will be measured is 234.87p (being the
average of the closing mid-market prices for Centrica plc for the period 1 April
2004 to 31 March 2005).

The conditional allocations shown above represent the maximum potential award
possible if all performance criteria are met at the end of the three-year
performance period. If and to the extent that performance criteria are satisfied
at the conclusion of the performance period, the relevant number of shares will
be transferred to executives at the trustee's discretion.

(1) The maximum allocation of shares only vests if the Company's TSR over the
performance period is ranked in 25th position or above in the Comparator Group.
No shares vest if the TSR over the performance period is ranked below 50th
position in the Comparator Group. From 25th to 50th position, shares vest on a
scale from 100% to 40%.

Total share interests held under LTIS for each Executive Director following this
notification are as follows:
