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

3^rd July 2012 that:

(1) The following Directors and other Persons Discharging Managerial Responsibility for the Company acquired Shares under the SIP on 2^nd July 2012 held through the Trustee:

* The 'Number of Shares Acquired' includes 40 Partnership shares acquired at 316.95 pence per share and 20 Matching shares acquired at 316.33 pence per share (39 Partnership shares and 19 Matching shares for Sam Laidlaw and Grant Dawson with a lower residual balance). Both the Partnership and Matching elements are registered in the name of the Trustee.

(2) The Trustee had transferred 20,000 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 the current month's allocation of Matching shares.

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.
