UK Petrol vs Diesel Price Gap Tracker
How much more does diesel cost than petrol in the UK right now? Live gap, historic context, and what it means for drivers.
What this study measures
Every figure on this page is recalculated from the live fuelfinder.ai price database — the same official CMA open data feed that powers our station search — rather than being written once and left to age. We take the median price per litre across all qualifying stations, exclude readings older than seven days, and drop obviously bad values below 80p or above 400p per litre so a single mis-keyed price cannot skew a brand or region.
How to use it
Use the figures below as a benchmark, then check what your own nearby stations are charging — the national picture and your local forecourt often differ by several pence a litre.

Prices come from the UK Government's Competition and Markets Authority (CMA) open fuel price scheme and refresh throughout the day. Figures older than seven days are excluded.
