About each brand

COSTCO WHOLESALE View brand page →

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.

Morrisons operates a substantial network of filling stations attached to its supermarkets, making it one of the UK's "big four" supermarket fuel retailers alongside Tesco, ASDA and Sainsbury's. Morrisons typically tracks ASDA's pricing closely, and the relaunched Morrisons More loyalty scheme (points-based, relaunched 2023) rewards fuel spend: members earn 5 More points per litre, with occasional double-points promotions. 5,000 points converts to a £5 "Fiver" voucher redeemable in-store or online. Morrisons also operates separate Morrisons Daily convenience-style forecourts, many of which are franchised — these may price differently to the main supermarket forecourts.
