Trading Update

Centrica plc (the "Company") has continued to deliver strong operational performance from its balanced portfolio since its Trading Update on 10 November 2022. Infrastructure asset availability and volumes have remained good, and we delivered incrementally strong optimisation performance.

All 2022 reported financial figures remain subject to audit and the Company is due to release its 2022 Preliminary Results on 16 February 2023.
