Wales has roughly one forecourt per 60 square miles, with supermarket competition concentrated along the M4 corridor between Newport and Swansea. Rural Powys, Ceredigion, and Gwynedd tend to lean more expensive than the South Wales coast, since independents in remote areas often have no nearby competitor and price accordingly.

Wales fuel prices: questions

Where is the cheapest fuel in Wales?+

Almost always along the M4 corridor between Newport and Swansea, where Tesco, Asda, Sainsbury's, and Morrisons compete for the same drivers. The current cheapest E10 station in Wales is shown in the stats card above and updates hourly.

Why is rural Welsh fuel so much more expensive?+

Rural Powys, Ceredigion, and Gwynedd often have a single independent forecourt covering large areas. With no nearby competitor, there's little pressure to keep prices low, and delivery costs are higher than for urban supermarket sites.

Are there many supermarket forecourts in Wales?+

Most are clustered around Cardiff, Swansea, Newport, and along the A55 in North Wales. Mid-Wales has very few; in some areas the nearest supermarket forecourt is over an hour away.

How often do these Welsh fuel prices update?+

Hourly, from the UK Government Fuel Finder service. Retailers are required to report price changes within 30 minutes.
