About Costco Fuel

Costco is a membership-only warehouse retailer, and its fuel stations offer some of the most competitive petrol and diesel prices in the UK. Located at Costco warehouse sites, these forecourts are exclusively available to Costco members, making them a popular choice for regular shoppers looking to maximise their membership value.

Costco fuel stations typically offer Unleaded (E10), Super Unleaded, and Diesel (B7) at prices that are often significantly lower than traditional forecourts and supermarket competitors. The stations are self-service and feature modern pay-at-pump facilities for a fast and efficient refuelling experience. Most Costco fuel stations operate during warehouse opening hours, though times may vary by location.

With a reputation for bulk savings and quality, Costco fuel is a go-to option for members seeking exceptional value on every tank. However, it's worth noting that a valid Costco membership card is required to access the pumps.
