Live Costco Fuel Prices Across the United Kingdom

Costco's UK fuel stations are reserved for current members and consistently price unleaded and diesel below the typical supermarket and motorway forecourt. The model is the same one Costco uses worldwide: fuel is a loss-leader run on thin margins to pull members onto the site, and the warehouse's buying power lets it undercut the big retailers. The forecourts are self-serve and usually open before the warehouse itself, so you can fill up early on the way to work.

You need a Costco membership. The pump reads your membership card before it will dispense, so fuel is members-only — there is no pay-and-go for non-members. Bring an active card to the self-serve forecourt.

Chip & PIN only — no cash or contactless. Costco UK forecourts take every major network by Chip & PIN: Visa, Mastercard, and American Express credit cards, plus Visa Debit and Maestro. Amex works here, unlike the Visa-only US and Mastercard-only Canada — but there is no cash, no contactless, and no Apple Pay or Google Pay at the pump, so bring the physical card and your PIN. Full details are in our Costco UK fuel payment methods guide.

Petrol, super unleaded, and diesel. Most warehouses sell standard unleaded petrol, super unleaded, and diesel, all priced in pence per litre and listed in the table below. Like every UK forecourt, the fuel meets the same British and European standards, whichever pump you use.

Prices change daily and vary by site. Pump prices track wholesale costs and differ from one forecourt to the next, so the figures on this page refresh daily from public sources. To find your closest location, use our UK Costco fuel station finder. As always, check the price on the pump display before you fill.
