Costco runs some of the cheapest forecourts in the UK — often the single cheapest place to fill up in an entire city. Here's everything drivers ask: live prices, opening hours, the membership rules, and the maths on whether it's worth joining just for fuel.
Quick answer: Costco fuel is member-only, pay-at-pump, and in July 2026 averages about 141p/litre for petrol and 153p for diesel — roughly 10p below the national average. Fuel stations typically open 06:30–21:30 weekdays, 06:30–20:00 Saturdays and 07:00–19:00 Sundays (varies by site). For a 12,000-mile-a-year driver the saving is ~£135/year, comfortably beating the membership fee.

Costco fuel station opening hours
Costco's petrol stations open longer hours than the warehouses — you don't need the shop to be open to fill up. Typical hours:
- Monday–Friday: ~06:30–21:30
- Saturday: ~06:30–20:00
- Sunday: ~07:00–19:00
Exact times vary a little by site (some open at 06:00, some close at 21:00), so check your local warehouse's page on Costco's site if you're cutting it fine. The pumps are unattended pay-at-pump: scan your membership card, pay by credit/debit card, fill up. No kiosk, no cash.
The membership rules
- Members only. Your membership card physically unlocks the pump — you can't pay your way in without one.
- Membership starts at around £60/year (Gold Star individual). Trade membership is cheaper if you qualify.
- One card, any Costco. Membership works at all 21 UK fuel sites (and abroad).
- Fuel quality is standard-spec. Kirkland Signature E10 and B7 meet the same BS EN standards as any UK forecourt, with detergent additives included.
Is Costco membership worth it for fuel alone?
The maths for a typical driver (12,000 miles/year at 40 MPG ≈ 1,360 litres):
| Scenario | Annual fuel saving |
|---|---|
| Costco ~10p/L below your local average | ~£135/year |
| Costco ~6p/L below a cheap local supermarket | ~£80/year |
| Low-mileage driver (500 L/year), 10p/L | ~£50/year |
Against a ~£60 membership: if you drive average miles or more and a Costco is on a route you already travel, membership pays for itself on fuel alone — everything you save in the warehouse is a bonus. For low-mileage drivers or if the nearest Costco is a long detour, the case is weaker: burning an extra litre of fuel to save £2 defeats the point.
Costco vs supermarket fuel
Supermarkets (Asda, Tesco, Sainsbury's, Morrisons) usually price 4–8p below the national average; Costco typically goes further, at 8–12p below. But supermarkets are everywhere and need no membership. The practical strategy:
- Near a Costco + member? It's almost always your cheapest option — verify on the map first.
- No Costco nearby? Supermarket forecourts are the next best — see supermarket vs branded fuel.
- Whatever you do, compare first. The spread within one town is often bigger than any brand rule of thumb. Our live map sorts every forecourt near you by price, free, updated every 15 minutes.
