The Motor Fuel Price (Open Data) Regulations 2025

The Secretary of State introduced regulations creating an open data scheme for motor fuel prices, establishing an aggregator, imposing data submission duties on fuel traders, granting enforcement powers to the CMA, and setting financial penalties and procedural appeals.


These Regulations, made under the Data (Use and Access) Act 2025, establish a mandatory open data scheme requiring motor fuel traders in England, Wales, Scotland, and Northern Ireland to register their petrol filling stations and report the selling price of motor fuels to an appointed third-party 'aggregator'.

Motor fuel traders must provide this price information, including any subsequent changes within 30 minutes of occurrence, for public dissemination via an Application Programming Interface (API) and other means.

The Competition and Markets Authority (CMA) is responsible for enforcement, with powers to issue compliance notices, conduct investigations, impose financial penalties up to 1% of worldwide turnover, and pursue criminal sanctions for false information or obstruction.
