Petrol and diesel prices, updated within 30 minutes by law
Every UK forecourt now has to report its prices. Search around a postcode or along your commute, see them on a map, and stop paying the A-road price.
Every forecourt, by law
Since February 2026 every UK forecourt must report its prices to the Fuel Finder scheme within 30 minutes of a change. That is what you are searching.
Near home or along the way
Search around a postcode, or type the start and end of your commute to see the cheapest stops within two miles of the route.
Log what you paid
Scan the receipt after you fill up and the saving, or the overpayment, lands on your Cash Saved ledger.

Fuel moves a few pence a week and nobody watches it every day. Tell us which fuel you buy and how far you will drive for it, and you get one email when the cheapest forecourt near you moves — down, so you know when to fill up, and up, so you know when to shop around.

Branded or supermarket?
Every litre of petrol sold in the UK has to meet the same British Standard (BS EN 228), and every litre of diesel BS EN 590. A supermarket cannot sell a lesser grade any more than a branded forecourt can. Most of it starts as the same base fuel from the same refineries and shared terminals; what differs is the additive package each company puts in at the terminal, and the price on the pole.
Additives matter less than the marketing suggests. Every standard fuel already contains the detergents the standard demands. Branded “premium” grades carry stronger detergent packages and, for petrol, a higher octane rating. That helps an engine designed for it. For the engine in most family cars it makes no measurable difference to economy, power or reliability, and no independent test has shown otherwise.
The money is in the standard grades. The gap between the cheapest supermarket and a branded forecourt on the same road is often 5p to 10p a litre, which is £2 to £5 every tank, £100 to £250 a year for an average driver. That is the figure worth chasing, and the list above shows it for your postcode today.
Supermarket standard fuel is right for you if
Paying more can be worth it if
If a forecourt sells you fuel that harms your car, that is a trading standards matter regardless of brand. Keep the receipt; scanning it here keeps a copy of what you paid and where.
Since 2 February 2026 every forecourt in the UK must report its prices to the government's Fuel Finder scheme within 30 minutes of a change at the pump. You see those reported prices here through the day, with when each one was last reported.
Fuel brings people to the shop, so supermarkets run thinner margins than a standalone station and far thinner than motorway services. The same litre can vary by 10p or more within five miles, which is why the spread figure matters more than the headline.
Type the postcode you leave from and the one you arrive at. You get every forecourt within two miles of the straight line between them, in the order you would pass them. It is a good approximation for most commutes; the map shows you exactly where each one sits.
E10 is standard unleaded and is right for almost every petrol car made since 2011. E5 is super unleaded, about 10p a litre dearer, needed only for some older or high-performance engines. Check your handbook or the GOV.UK E10 checker if you are unsure.
Yes, B7 is standard diesel. Premium diesel with a brand name costs more and offers no saving for a normal car. HVO is a renewable diesel some forecourts now sell; it is listed separately where reported.
Yes. Scan the fuel receipt after you fill up and you see what you paid against what was available nearby at the time. The difference lands on your Cash Saved ledger, or you find out you already got the best price.
