Google Maps now shows petrol and diesel prices in the UK. Here's how to use it

Google Maps and Waze now show petrol and diesel prices at UK filling stations. Google launched the feature on 8 October, and it uses the same live price data that every forecourt in the country is now legally required to share.

The timing matters. Diesel went above £2 a litre on average for the first time at the start of October, and it is still sitting just under that line.

How to see the prices

Open Google Maps or Waze and search for fuel or petrol.
Prices for petrol and diesel appear on the map next to each nearby station.
Tap a station to see the prices for every fuel it sells in one place.

Google says it checks the data before showing it. If it is not confident a price is up to date, you will still see the station on the map, just without a price.

Where the prices come from

The data comes from Fuel Finder, a government scheme that started in February. Every petrol station in the UK has to report a price change within 30 minutes of making it. The government estimates that comparing prices this way could save a car-owning household around £40 a year, and the Competition and Markets Authority can act against stations that don’t share their prices.

Google Maps is not the only way to use it. Apps and sites such as RAC Fuel Watch and MotorMouth also show Fuel Finder data.

Is the data reliable?

Mostly, but not completely. Speaking to the BBC, the price comparison site PetrolPrices said some stations still have not signed up to Fuel Finder and others are slow to update. It said it found around 200 forecourts in September that it believed had not updated their diesel prices in time. The Petrol Retailers Association, which represents thousands of UK forecourts, said its members are following the rules.

The practical takeaway: use the app to find the cheapest station nearby, but check the price on the pump before you fill up.

What fuel costs right now

According to the RAC’s figures for 9 October 2026:

Diesel: 199.90p a litre on average, down slightly from the record 200.01p. A 55-litre tank costs about £110.
Petrol: 174.79p a litre. A 55-litre tank costs about £96.

Both are far above where they were before the US-Iran conflict began on 28 February: diesel is up 57.5p a litre and petrol 42p. The gap between stations is large, too. When PetrolPrices last checked, the cheapest diesel it tracked was 142.9p and the most expensive 234.9p, which is why comparing before you drive somewhere is worth a minute.

What could change next

Fuel duty is set to rise by 3p a litre on 1 January and another 2p on 1 March unless the government changes course. The RAC is asking for the current duty cut to be extended in the upcoming Budget. We will update this page if anything changes.
