Best Apps for Finding Cheap Fuel in the UK

The Hunt for Cheap Fuel

Gone are the days of driving around town burning expensive fuel just to see which station has the best price board. In 2026, finding the cheapest petrol and diesel requires nothing more than a quick tap on your smartphone. But with so many tools available, which one should you use?

The Official Solution: FindPetrol

We built FindPetrol.co.uk to be the fastest, most reliable tool on the market. Unlike older crowd-sourced apps that relied on users manually reporting prices (which often led to out-of-date or incorrect information), FindPetrol taps directly into the official UK Government Fuel Finder API.

This means our data covers nearly 8,000 forecourts-including BP, Shell, Esso, Tesco, Asda, Sainsbury's, and Morrisons-and is updated every 5 minutes. You get guaranteed accuracy without having to download a clunky app or create an account.

Waze

Waze is primarily an incredible navigation app, but it also features a built-in fuel price tracker. Because it relies heavily on its community of drivers to update prices, its accuracy can be hit-or-miss depending on how many active Waze users live in your specific town. However, for seamless navigation directly to a pump, it remains a fantastic tool.

Supermarket Apps

If you are fiercely loyal to a specific brand, their official apps (like the BPme app or the Tesco Grocery app) can be useful. However, they only show you prices for their own stations, blinding you to the fact that the independent station across the street might be 5p a litre cheaper today.

The Verdict

For sheer speed, privacy (no account required), and government-backed accuracy, bookmark FindPetrol.co.uk on your phone's home screen. A quick 10-second search before you set off can easily save you £5 to £10 on a full tank of fuel.

Prices vary widely between sites even within one chain - see current Tesco fuel prices across the UK.

Where to find the cheapest fuel near you

Supermarket forecourts usually undercut the oil majors, but the gap varies enormously by town - a competitive independent will often beat a supermarket that has no rivals nearby. You can compare every UK fuel brand side by side, or search your postcode to find the cheapest petrol near me right now. The UK average is currently 161.4p a litre across 7,916 stations.
