Monthly UK fuel price reports
What petrol and diesel actually did each month, measured from daily prices at every forecourt in the government's Fuel Finder scheme rather than from a sample. National medians, the supermarket gap, the motorway premium, every brand and every postcode area, from March 2026 to August 2026.

For journalists and researchers
Everything in these reports may be quoted or reproduced with a link to the month it came from. The underlying data is free to download from the data page as CSV and JSON, under the Open Government Licence that covers the Fuel Finder feed.
A new report is published in the first few days of each month. If you would like the figures cut a particular way — a single county, a town, one brand's forecourts, a longer run of history — that is usually a few minutes of work rather than a favour, so please ask.
What the numbers mean
- Medians, not averages. Retailers occasionally publish a mistyped price. An average moves when one forecourt reports 299.9p; a median does not.
- Spreads use percentiles. Cheapest-to-dearest figures are the tenth and ninetieth percentiles rather than the extremes, for the same reason.
- Prices are what retailers published, not what a mystery shopper paid. The Fuel Finder scheme requires forecourts to publish price changes within half an hour.
- Nothing here is an estimate or a forecast. Every figure is arithmetic on recorded prices, and the method is the same every month.
