Beginning on 1 May, the Competition and Markets Authority can begin fining UK petrol stations that fail to report price changes to the government's Fuel Finder system within 30 minutes.
After a three-month grace period, the rules now have teeth and a compliance gap has already emerged. Since 2 February 2026, every petrol station in the UK has been legally required to report any change in pump prices to a central government database.
For the first three months, the Competition and Markets Authority, which has the job of enforcing the scheme, said it would focus on supporting forecourts to comply rather than handing out fines.
That grace period ended on Friday 1 May 2026. From that date, the CMA has confirmed it will start prioritising enforcement action against non-compliance, including formal investigations and financial penalties.
