Summary

What changed
The CMA has issued an open letter requiring all road fuel retailers to register with Fuel Finder, the Open Data scheme for fuel prices, and submit price updates within 30 minutes of any change. This guidance follows the CMA's stepped-up monitoring of petrol and diesel prices in light of the conflict in the Middle East. From 1 May 2026, the CMA will use its enforcement powers to start prioritising action against non-compliance if information indicates formal action may be appropriate.
Road fuel retailers must immediately register with Fuel Finder and ensure their pricing systems can report updates within the 30-minute window. Retailers should review the CMA's Fuel Finder enforcement guidance to understand compliance expectations. Non-compliance after 1 May 2026 may result in formal enforcement action by the CMA.
What to do next
- Register immediately with Fuel Finder using the CMA's sign-up process
- Implement systems to report fuel price changes within 30 minutes of any change
- Review the Fuel Finder enforcement guidance to understand compliance obligations
