A new rule now means UK petrol stations must share fuel price changes quickly, making it easier for drivers to find cheaper petrol.
UK petrol stations now have a legal duty to report fuel price changes to a central database within 30 minutes.
The rule came into force on 2nd February 2026 and applies to:
- Independent petrol stations
- Supermarket forecourts
- Large fuel chains
This change is designed to make fuel costs easier to manage. Industry estimates suggest drivers could save between 1p and 6p per litre by choosing cheaper fuel more often, based on improved price visibility.
