Live local stations, cheapest prices, and map
Cardiff fuel prices are grouped from a curated city-to-postcode match so users and search engines can browse a stable local landing page instead of relying on inconsistent town names in the source data. Use this page to compare cheapest petrol in Cardiff, cheapest diesel in Cardiff, and nearby postcode districts.
This city page is designed as a crawlable local hub first and an interactive map second. The server-rendered tables give Google stable station links and fresh price text, while the map/table UI lets users narrow the list to a 5 mile radius once they share location or enter a postcode.
In the latest Cardiff snapshot, diesel sits above petrol by about 18p per litre between the cheapest listed E10 and B7 forecourts. Use that spread to judge whether your next stop is being driven by pump price alone or by fuel-type availability.

For Cardiff, the lowest listed price is a good starting point, but it is not always the best stop once travel time and route direction are included. Open the station detail page, compare nearby alternatives, and use the map to check whether the saving is worth a detour before filling up.
Within Cardiff, prices often split by supermarket clusters, commuter corridors, and edge-of-city filling stations. Use the postcode buttons on this page, compare the cheapest E10 and B7 lists, and check nearby city pages in Wales if your trip crosses more than one local area.
If you do not need to refuel immediately, compare today's local snapshot with the monthly trend archive and set a fuel price alert from the sidebar. That is usually more useful than refreshing one station repeatedly, especially when wholesale moves are pushing petrol and diesel in opposite directions.
