About Costco Wholesale fuel

Costco operates members-only forecourts attached to its UK warehouses (around 29 sites nationwide). Accessing the pumps requires an active Costco membership — Gold Star at £42/year or Executive at £70 + VAT — and the forecourt scanner checks your membership card before dispensing fuel. Costco is often one of the cheapest consumer-facing fuel brands in the UK on a pence-per-litre basis, but the network is thin: you need to live within realistic driving distance of a warehouse for the savings to work. Forecourts open and close with the warehouse, so Costco is not an option for late-night or early-morning fills. Note that fuel purchases are excluded from Executive membership's 2% cashback rewards.

  • Membership required: Gold Star £42/year or Executive £70 + VAT to use the forecourt.
  • Only E10 unleaded and B7 diesel — no super unleaded, no premium diesel.
  • Open only during warehouse hours — check local warehouse opening times before driving out.
  • Fuel is excluded from Executive membership's 2% cashback rewards.
