Prices are published by the retailers themselves under the government's fuel price transparency scheme and are shown in pence per litre. A forecourt only appears here once it has actually reported, and we show its reported date rather than assuming today's price. Prices can change between a retailer reporting and you arriving, so always check the pump.
Common questions about fuel in Cardiff
Every answer below is worked out from the forecourt prices on this page.
Where is the cheapest diesel in Cardiff?
Asda Leckwith Road Superstore, CF11 8AZ, at 196.7p a litre. That is the lowest diesel price of the 22 Cardiff forecourts reporting it. The retailer reported it today (18 Oct 2026). Prices can change between a retailer reporting and you arriving, so check the pump.
How many petrol stations in Cardiff report their fuel prices?
We hold a recently reported price for 29 forecourts in Cardiff, published by the retailers themselves under the government's fuel price transparency scheme. That is what has reported recently enough for us to list, rather than a count of every forecourt in Cardiff — a site that stops reporting drops out, and one that has never reported never appears. Not every forecourt sells every fuel: 22 quote unleaded, 17 quote super unleaded, 22 quote diesel, 8 quote premium diesel. All 22 of the forecourts quoting diesel are ranked on this page.
Is diesel cheaper in Cardiff than the UK average?
Cardiff averages 198.7p for diesel across the 22 forecourts quoting it, which is 0.2p a litre cheaper than the UK average of 199.0p. The UK figure is taken over the 6,153 forecourts that reported a price in the most recent GOV.UK snapshot, out of the 8,136 forecourts we currently list, so it is not limited to Cardiff.
How up to date are these Cardiff fuel prices?
Every price on this page was reported today. Retailers report into the scheme themselves, anywhere from daily to occasionally, so no price here is a live pump price — each one is shown with the date it was reported.
How much can I save by shopping around for diesel in Cardiff?
Diesel runs from 196.7p to 203.9p across the 22 Cardiff forecourts quoting it — a gap of 7.2p a litre, or about £3.60 on a 50-litre fill, if both prices still stand when you get there.
