Retailers must report a price change to the government's Fuel Finder scheme within 30 minutes, so a forecourt that last reported a few days ago simply has not changed its price. Opening hours are each retailer's own entry in the scheme.
1 station has stopped reporting (more than 14 days) and is left out of every figure above
- Rontec Penrhos, last reported 16 days ago
A price that old is not a current market price, so we do not show it as one. These stations may have closed, changed hands or dropped out of the scheme.
