About each brand
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.
Tesco is one of the UK's largest supermarket fuel retailers, with filling stations attached to most of its Extra and Superstore branches. Fuel at Tesco is largely a convenience product designed to drive grocery footfall, which is why prices sit close to other supermarkets and typically undercut oil-major brands like Shell and BP on standard grades. Tesco forecourts adjust their prices locally, so sites near other supermarkets tend to be more aggressive than rural Tesco sites with less nearby competition. Tesco is a Clubcard partner on fuel, with the standard collection rate at 1 point per 2 litres and enhanced rates for Clubcard Pay+ and Tesco Bank credit card holders.
