Tanki is a free fuel price comparison tool for UK drivers. We help you find the cheapest petrol, diesel, and EV charging stations near your location — saving you money on every journey.
Fuel is one of the biggest regular expenses for UK households. The difference between the cheapest and most expensive station in your area can easily be 10p per litre — that's £5.50 on a single fill-up, or nearly £300 a year.
We built Tanki to make it effortless to find the best price. No sign-up, no ads getting in the way, no nonsense. Just open the app and see what's cheapest near you.
We take data accuracy seriously. All our pricing comes from official and verified sources:
Official UK government API. Retailers with 100+ stations must report price changes within 30 minutes. Our primary data source.
For retailers not yet on the government API (Asda, Esso, Applegreen), we source prices directly from their published data.
Global open-data registry for EV charging locations. Community-maintained with data from operators and users worldwide.
Open-source UK postcode geocoding. Used to convert postcodes to coordinates for accurate distance calculations.
