Director/PDMR Shareholding

Centrica PLC

Purchase of ordinary shares of 6 ^14/81 pence in Centrica plc (“Shares” and the “Company”, respectively) by Directors of the Company and Persons Discharging Managerial Responsibility (PDMRs) under its Share Incentive Plan (“SIP”).

The SIP trustee, Equiniti Share Plan Trustees Limited (the “Trustee”), notified the Company on 5 May 2010 that:

(1) The following Directors and other Persons Discharging Managerial Responsibility for the Company acquired Shares under the SIP on 4 May 2010 held through the Trustee:

	Â	Number	Â	Aggregate Shares held
		Of Shares		Beneficially (across all accounts
Directors		Acquired*		following acquisition)
Phil Bentley		61		2,180,555
Sam Laidlaw		63		1,823,484
Nick Luff		61		624,013
Chris Weston		63		497,024
Mark Hanafin		63		318,824
					Â
Persons Discharging Managerial Responsibility
Grant Dawson		63		418,205
Catherine May		63		202,874
Anne Minto		63		454,442

* The ‘Number of Shares Acquired’ includes 42 Partnership shares acquired at 298.47 pence per share (41 Partnership shares for Phil Bentley and Nick Luff with a lower residual balance) and 21 Matching shares acquired at 296.1 pence per share (20 for Phil Bentley and Nick Luff). Both Partnership and Matching elements are registered in the name of the Trustee.

(2) The Trustee had transferred 18,000 Shares from Equiniti Corporate Nominees Limited AESOP1 (Allocated shares) to Equiniti Corporate Nominees Limited AESOP2 (Unallocated shares). The transfer was made following the forfeiture of shares, under the rules of the SIP, by participants who have left the group since the last purchase and the shares had been used towards February’s allocation of Matching shares.

The share transactions in respect of the DMSS release included in the 7 April announcement were incorrectly notified to the Company by the trustee and as a result the aggregate number of ordinary shares of 6 14/81p held by Phil Bentley, Sam Laidlaw, Chris Weston and Catherine May have been reduced by 906, 1269, 394 and 79 shares respectively. The respective totals shown above reflect this adjustment and the monthly May SIP purchase. All other information in the prior release remains unchanged.

For local Canadian tax reasons, Chris Weston has been allocated a notional entitlement of 54,898 shares under the terms of the DMSS not included above.

Notes:

The SIP is made available to all UK employees and operates as follows:

• Each month the Trustee uses participants’ contributions (which may not exceed £125 per participant per month) to purchase shares in the market. These shares are called ‘Partnership Shares’.
• At the same time the Company allots to participants via the Trustee one ‘Matching Share’ for every two partnership shares purchased that month (up to a maximum of 22 matching shares per month).
• Participants may change their monthly savings rate whenever they wish. However, Directors and others bound by the Company’s Securities Dealing Code (the “Code”) may not make such a change during a close period or when otherwise prohibited from dealing by the Code.
