Common questions
Which supermarket has the cheapest fuel?
Today Costco has the lowest typical petrol price of the supermarkets we track, but it moves week to week and the cheapest forecourt near you is not always a supermarket. The table above ranks them, and the postcode search finds the cheapest of any kind near you.
Is supermarket fuel cheaper than branded stations?
Usually, yes. Supermarkets use fuel to pull shoppers in, so their forecourts sit among the cheaper options, though a competitive non supermarket station can still beat them locally. Our guide on why supermarket fuel is cheaper explains how.
Is supermarket petrol lower quality?
No. All UK fuel meets the same standard and comes from the same refineries and terminals. The only difference is the additive mix. See is supermarket fuel bad for your car for the full answer.
