## About fuel in Cardiff

Cardiff has the densest concentration of forecourts in Wales and typically the country's most competitive prices, with the big supermarket sites off the A48 and around Cardiff Bay leading on price.

**Local tip.** Welsh fuel prices rise sharply once you head into mid and west Wales, where forecourts are sparse. Cardiff, Newport and Swansea are the cheapest fills in the country.
