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.

3 stations have stopped reporting (more than 14 days) and are left out of every figure above

Asda Colsterworth Express Petrol, last reported 29 days ago
Jubilee Service Station, last reported 28 days ago
Ancaster Service Station, last reported 23 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.
