With fuel prices fluctuating week to week, finding the cheapest petrol near you can save a surprising amount over the year. A typical UK household spends over £1,500 on fuel annually — even a 5p per litre saving adds up to over £100 a year for regular drivers.
This guide covers practical, proven ways to find cheaper fuel wherever you are in the UK.
Check prices now
Enter your postcode to find the 5 cheapest fuel stations near you, ranked by price, distance and data freshness.
Search your postcode1. Use a fuel price comparison tool
The single most effective way to find cheap petrol is to check prices before you drive. Fuel prices can vary by 10–15p per litre between stations just a few miles apart — that's £5–8 difference on a full tank.
PumpCheck lets you compare prices by postcode in seconds. Prices come from the UK government's Fuel Finder scheme and are updated throughout the day.
Try it now: search for CF10 (Cardiff), SW1A (Westminster), or M1 (Manchester).
2. Supermarkets are usually cheaper
Supermarket fuel stations (Asda, Sainsbury's, Tesco, Morrisons) consistently offer lower prices than branded forecourts. They use fuel as a loss leader to attract shoppers, often pricing 3–7p per litre below the local average.
That said, the cheapest station near you isn't always a supermarket. Independent stations, Costco (members only), and some smaller brands can be competitive. Compare prices rather than assuming — check brand price trends to see who's cheapest this week.
3. Don't drive miles to save pennies
A common mistake is driving 10 miles out of your way to save 2p per litre. On a 50-litre fill, that saves £1 — but the extra 20-mile round trip costs roughly £3 in fuel at current prices.
That's why PumpCheck ranks stations by a composite score of price, distance, and data freshness rather than just cheapest price. The best value station is often the one that's cheap and close.
4. Fill up on the right day
UK fuel prices tend to be slightly lower mid-week (Tuesday–Wednesday) and higher at weekends, though the difference is usually only 1–2p. More significantly, prices often drop after wholesale cost reductions — but retailers are slow to pass savings on.
Rather than trying to time the market, the best strategy is to fill up when your tank hits a quarter rather than waiting until empty. This gives you flexibility to choose a cheaper station rather than being forced into the nearest one.
Check UK fuel price trends to see if prices are rising or falling.
5. Choose the right fuel type
Most cars run perfectly well on standard E10 unleaded, which is typically 8–12p per litre cheaper than super unleaded (E5). Unless your car specifically requires E5 (check your fuel cap or manual), there's no benefit to paying more.
Similarly, "premium" diesel rarely offers meaningful benefits for standard diesel cars. Save the premium for the cars that actually need it.

6. Drive more efficiently
You can cut fuel consumption by 10–15% with simple driving habits:
- Keep to the speed limit — driving at 70mph uses up to 9% more fuel than 60mph
- Accelerate gently and anticipate stops
- Remove roof racks and boxes when not in use
- Check tyre pressures monthly (under-inflated tyres increase rolling resistance)
- Turn off the engine if you're stationary for more than a minute
Summary
The fastest win is comparing prices before you fill up. The second is not driving past a cheap station to find a marginally cheaper one further away. PumpCheck handles both by ranking stations on value, not just raw price.
