Fuels: Prices
The question
To ask the Secretary of State for Energy Security and Net Zero, with reference to the press release entitled Fuel margins remain “persistently high” and this is not explained by operating costs, CMA finds, published on 22 December 2025, if he will make an assessment of the potential implications for his policies of the Competition and Markets Authority findings on the pricing behaviour of large supermarket fuel retailers.
Answered by Martin McCluskey
We welcome the CMA’s work monitoring road fuel prices and note its findings of 22 December 2025. The Government is committed to ensuring drivers get a fair deal and is implementing an open data scheme, Fuel Finder, which will provide near real time fuel price information to increase transparency in the market. The scheme will be reviewed within three years, including it has helped to reduce fuel prices. This review will consider implications across the sector, including large supermarket fuel retailers.
The CMA will use Fuel Finder data to inform its ongoing market monitoring assessments, supporting transparency and competition in the market.
