Cheapest Fuel Near Carmarthen

Why We Do This

We built this page for the people of Carmarthen — to make the cheapest fuel easy to find. With about 14,185 people living in Carmarthen, even 20% of them saving 1p a litre would keep about £19,000 a year in local pockets — and at 5p a litre, about £99,000.

If saving a few pence a litre means a little more for the things you need, that's a good day's work for us.

Based on: population 14,185 (OpenStreetMap figure); 6,200 miles a year for an average petrol car (DfT National Travel Survey 2024, NTS0901); 40 mpg (our assumption) = about 704 litres a year each. Figures rounded down.
