Frequently Asked Questions

PetrolFinder UK is a free fuel price comparison tool that helps you find the cheapest petrol, diesel, and other fuels near any UK postcode. We cover over 7,500 petrol stations across the entire United Kingdom.

Yes, completely free. There are no subscriptions, no premium tiers, and no hidden costs. We believe everyone should have access to transparent fuel pricing data.

We use official government data from the UK Fuel Finder scheme (CMA Open Data), updated every 5 minutes. Unlike crowd-sourced sites, our prices come directly from fuel retailers who are legally required to report them.

Our data comes from the official UK Government Fuel Finder API, operated under the Competition and Markets Authority (CMA) Open Data regulations. Fuel retailers with 100+ stations are legally required to submit prices, and we sync this data every 5 minutes.

We sync with the government API every 5 minutes, 24/7. However, individual stations may update their prices at different times — some update daily, others several times a day. We show the last update time on every station card so you know how fresh the data is.

While prices come from official sources, there can be a delay between a station changing its pump price and the data being updated in the government system. We recommend checking the 'last updated' timestamp on each price. If a price was updated more than 24 hours ago, it may no longer be accurate.

We track Unleaded (E10), Super Unleaded (E5), Diesel (B7), Premium Diesel, Biodiesel (B10), and Renewable Diesel (HVO). Not all stations sell every fuel type.

The CMA mandate currently applies to retailers operating 100 or more fuel stations. Smaller independent forecourts may not be required to report prices. We show all stations in the database but some may have stale or missing price data.

The Best Value badge highlights the station with the cheapest price for each fuel type within your search results. It only considers stations with price data updated within the last 5 days.

Yes. On every station card, tap 'View Station' and then use the directions button to open Google Maps with turn-by-turn navigation to the station.

You can filter stations by: 24-hour opening, toilets, car wash, AdBlue pumps, AdBlue bottles, LPG, and air/water. Use the 'Amenities' button in the search filters to select what you need.

Amenity information comes from the same government fuel finder database. It's reported by the station operators themselves. If an amenity is missing or incorrect, it may not have been reported by the operator.

Yes! PetrolFinder is a Progressive Web App (PWA). On your phone, open the site in your browser, then tap 'Add to Home Screen' (iOS) or look for the install prompt (Android). It works offline for recently viewed pages and launches like a native app.

Yes. PetrolFinder is fully responsive and works on phones, tablets, and desktops. We recommend using a modern browser like Chrome, Safari, Firefox, or Edge for the best experience.

We take privacy seriously. We don't sell your data to third parties. If you use My Garage, your fill-up data is stored securely and only accessible to you. See our Privacy Policy for full details.
