Diesel Prices in Bristol
Today's cheapest diesel across Bristol and the South West, ranked pence per litre.
Diesel prices across Bristol are not one number — they are hundreds of them. On any given day the gap between the cheapest and most expensive diesel pump in the BS postcode area regularly exceeds 10p per litre, which is £5 or more on a single 50-litre fill.
This page tracks diesel only. fuelfinder.ai lists every Bristol forecourt that reports to the UK Government's CMA Pump Watch open-data scheme, ranks them by diesel pence-per-litre, and shows how recently each price was confirmed. Standard UK diesel is B7 — up to 7% biodiesel, meeting the BS EN 590 standard whether you buy it from a supermarket or a branded forecourt.

Frequently Asked Questions
Where is the cheapest diesel in Bristol today?
It changes daily. Supermarket forecourts — Asda, Tesco, Sainsbury's, Morrisons and Costco where present — usually lead on diesel in Bristol, typically 5–10p below the branded majors. Search your postcode above for today's actual ranking rather than relying on a rule of thumb.
How much does diesel cost in Bristol right now?
The live table on this page shows the current cheapest, median and most expensive diesel price reported across Bristol. Figures come from the CMA Pump Watch feed and refresh twice daily, so they reflect what retailers have officially declared.
What grade of diesel do Bristol stations sell?
Standard UK diesel is B7 — up to 7% biodiesel, meeting the BS EN 590 standard whether you buy it from a supermarket or a branded forecourt.
Is premium diesel worth it in Bristol?
Premium diesel adds detergent and cetane-improving additives. It costs roughly 10–15p per litre more and is rarely worth it for ordinary commuting.
Why is diesel cheaper in some parts of Bristol?
Local competition is the biggest factor. Where two supermarkets sit within a mile of each other, both price aggressively. Sites with no nearby rival — city-centre forecourts, or stations on a single-approach road — have no pressure to match, and Bristol pump prices reflect that.
How often is Bristol diesel price data updated?
Retailers submit to the CMA scheme through the day and fuelfinder.ai refreshes twice daily. Each station row shows its own last-updated time, so you can see whether a price is hours or days old before you drive to it.
