Make the estimate work for your area
This calculator uses UK averages by default, but local prices can move quickly. Cross-check your result with county-level averages or the live price map to see whether today's prices are above or below national trends. We always highlight freshness so you can spot when a number might be stale.
If you are planning a longer drive, use the route planner to compare stations along the way and decide whether a small detour is worth it.
