UK fuel prices by brand
Costco is currently the cheapest major brand at 166.9p a litre on average, with BP the dearest at 177.1p - a gap of 10.2p, or about £5.09 on a 50 litre fill.
Every retailer in the UK buys fuel from the same handful of refineries and terminals, so the differences below are not about the fuel itself. They come down to business model: supermarkets use the forecourt to pull shoppers into the store and price accordingly, while the oil majors carry the cost of brand, premium grades and sites in places a supermarket would never build.
Averages hide a lot of variation. A well-placed Shell in a competitive town can undercut a Tesco with no rivals nearby, so treat the table as a guide to where to look first rather than a rule. The brand pages below break each network down by region and town.
