Wales

Diesel demand reflects agricultural and tourism traffic, while petrol use rises during summer holidays and rugby internationals. Drivers heading into Snowdonia, the Brecon Beacons, or the west coast should plan refuelling in larger towns like Aberystwyth, Wrexham, or Carmarthen.

Prices in remote areas may differ from the urban average due to transport costs. Wales rewards drivers who plan fuel stops around the dramatic geography.

Understanding regional price patterns supports smooth journeys between cities and the most scenic corners of the country. Prices often open up once you move away from the busiest retail parks or get closer to motorway services.

If you are crossing Wales rather than just driving locally, a quick check before you set off can save a useful amount on a full tank. Use the snapshot below for the current range, then drill into the town and city pages if you want more detail.

A short detour before you join a motorway or trunk road is often cheaper than waiting for the first convenient stop after you are already moving.
