About our data

Where prices come from

Fuel retailers report their pump prices to Fuel Finder, run by the Department for Energy Security and Net Zero. It is the same data behind the government’s own price comparison. Fuelsy covers 8,252 forecourts across England, Scotland, Wales and Northern Ireland, with each station’s prices, address, opening hours and facilities.

The data is published under the Open Government Licence v3.0. It contains public sector information licensed under that licence.

How often they update

• We check Fuel Finder for new prices every 2 minutes, and for station details such as hours and closures every hour.
• The pages on this site, Near me and your saved forecourt refresh their prices about every 15 minutes.
• Each price sign shows the time its prices were updated.

Every price change is recorded, which is how we can show a station’s price history.

How we choose the cheapest

The cheapest price is the lowest price we trust. We leave a price out when:

• it is below 50p or above 300p a litre, or our checks flag it as unusual for that station;
• it hasn’t been updated in 14 days, or the station has stopped reporting regularly, so it is probably out of date;
• the station is marked as temporarily closed.

Station pages still show these prices, marked, so you can see what was reported.

Averages and trends

• UK averages are the mean price across every forecourt reporting that fuel.
• Area figures use the median, the middle price, so one very cheap or very dear forecourt doesn’t skew a small area.
• The price chart shows our daily UK average, recorded since April 2026, with today’s live average as the last point.
• Supermarket and motorway comparisons set the average at those forecourts against every other forecourt.

Unleaded means E10 petrol, super unleaded E5, diesel standard B7, and premium diesel the higher-grade diesel some forecourts sell.

Fill up now or wait

The light on each price sign says whether prices in that area are moving. It comes from the last 7 days:

• Rising when the area’s median price has gone up by 2p or more while the UK average has gone up by 1.5p or more. Filling up sooner is likely to cost less.
• Falling when both have come down by the same amounts. Waiting a few days is likely to cost less.
• Steady otherwise, and we don’t show a light.

The percentage beside it, such as “70% of stations”, is how often stations moved another penny or more within a week the last times prices behaved like this. It describes the past, not a promise.

What the data can’t tell you

• Some small independent forecourts don’t report to Fuel Finder, so they aren’t on Fuelsy.
• New stations can take a little while to appear.
• Retailers report their own prices, and some report changes later than others. The pump price is the one you pay.
