How often do fuel prices change in the UK?
Published - 3 min read
How often UK petrol and diesel prices change, what makes them move, how quickly forecourts must report changes under Fuel Finder, and how to keep up.
Prices move more often than you'd think
Some forecourts change prices several times a week; others hold steady for longer. Supermarkets often react quickly to each other, and stations near a competitor tend to move together.
What makes them change
- Wholesale fuel costs, which follow the oil price and the pound against the dollar.
- A competitor nearby changing its price.
- Changes in tax, such as fuel duty or VAT.
Keeping up
Under the Fuel Finder scheme, forecourts must report price changes promptly, so up-to-date prices are available to compare. Pennyfill shows when each price was reported, and Pro alerts you when prices near you drop.
