Map methodology

107 of 112 regions currently qualify for ranking from fresh or aging data. 18 regions are currently flagged as low sample.

Methodology and freshness checks

Regional rankings use stations with fresh and aging updates first. Regions without enough recent data are flagged, so you can avoid over-trusting thin samples.

Averages are comparative indicators, not guaranteed fill-up prices. Use each county or district page to confirm station-level timestamps and confidence before travelling.

Fuel type
