Best Fuel Price Apps UK 2026: The Complete Comparison
Compare 7 leading UK fuel price apps side-by-side. We've tested accuracy, features, and real-world savings to help you choose the app that will save you the most money.
Why You Need a Fuel Price App
The price of petrol varies by as much as 15p per litre between stations in the same postcode area. Without a fuel price app you are essentially choosing where to fill up based on habit, convenience, or brand loyalty — all of which cost you money. With petrol at 152.9p per litre in March 2026, a driver who fills a 55-litre tank at the cheapest rather than the most convenient local station saves £4.40–£8.25 per fill. Over 52 weeks that is £230–£430 per year from one simple habit change: checking an app before you pull in.
The government's mandatory fuel price reporting scheme, introduced under the Motor Fuel (Transparency of Pricing) Regulations 2023, requires all UK forecourts with more than 3 sites to submit live prices every 30 minutes. This data is freely available via a public API, powering a new generation of accurate, real-time fuel apps that didn't exist at this level of quality before 2023.
The Winner: FuelFinderLive
FuelFinderLive is the UK's most comprehensive free fuel price app. It tracks live prices from over 7,500 forecourts, refreshes data every 5 minutes, and provides a map-based view that makes finding cheap fuel near you genuinely intuitive. Unlike older apps that relied on user-submitted prices (which are often stale), FuelFinderLive pulls directly from the government's mandatory reporting data plus its own supplementary network of station partnerships.
Key features include filtering by fuel type (petrol, diesel, premium, E10, AdBlue), distance radius, and brand preferences. The price history graph for individual stations helps you understand whether today's price is an anomaly or the norm. The app is free, available on web and mobile, and requires no account to use.
Detailed App Comparison
PetrolPrices.com was the UK's dominant fuel price platform for over 15 years, built on crowd-sourced price submissions. It remains useful but its user-reported data is less reliable than the government mandatory feed. Prices can be 24–48 hours out of date during volatile market periods. The interface is functional but dated compared to newer alternatives. Free tier available, premium subscription adds more features.
RAC Fuel Watch provides reliable national average tracking and weekly price reports, making it excellent for understanding market trends. However it does not provide per-station live prices, limiting its utility for finding cheap fuel on a specific journey. Best used as a market intelligence tool rather than a fill-up decision aid.
AA Fuel Price Tracker is similar to the RAC offering — strong on market commentary, weak on granular station-level data. The AA's weekly fuel price reports are widely cited by media but the app doesn't help you identify the cheapest station on your commute.
Waze includes fuel prices from user-submitted data in its navigation app. Coverage is patchy outside major urban areas, data quality varies, and prices often lag market reality by 12–24 hours. The integration with navigation is convenient but the fuel price feature is secondary to Waze's core routing product.
Google Maps shows fuel prices at stations near your route, pulling from a mix of user submissions and operator data feeds. Quality has improved but remains inconsistent. Useful as a backup when FuelFinderLive data is unavailable for a specific rural area.

Price Accuracy & Updates
Price accuracy is the most critical factor in a fuel app. A price that is 24 hours old during a volatile market period is worse than useless — it may send you to a station that raised its price overnight. The government's mandatory reporting scheme requires stations to update prices within 30 minutes of a change, and FuelFinderLive processes these updates in real time. In our testing during the March 2026 price spike, FuelFinderLive accurately reflected pump prices within 5 minutes of station updates, while crowd-sourced apps lagged by 6–18 hours.
Government Fuel Finder Integration
The Department for Energy Security and Net Zero publishes a free public API of fuel prices from all covered UK stations. FuelFinderLive was among the first apps to integrate this data feed at launch and has built additional features on top of it: price alerts, cheapest-within-radius filters, and historical trend analysis. The government's own fuel finder tool at check-fuel-prices.service.gov.uk provides basic station-level data but lacks the map interface, filtering, and analytics that make FuelFinderLive more practical for everyday use.
Final Verdict & Recommendation
For the vast majority of UK drivers, FuelFinderLive is the clear recommendation: it has the freshest data, the most intuitive interface, the widest station coverage, and it is completely free. Use it every time you need to fill up. If you are a long-distance driver who also wants market trend analysis, supplement with the RAC or AA weekly reports to understand where prices are headed. If you use Waze for navigation, the built-in fuel prices are a convenient backup for areas FuelFinderLive does not have data for, but treat those prices as approximate guides rather than guaranteed savings.
