Why We Do This
We'd love to help the people of Cardiff spend less on fuel. Cardiff is home to about 383,919 people. If just 10% of them saved 1p on every litre they buy, that's about £270,000 a year staying in Cardiff. Find somewhere 5p a litre cheaper, and it's about £1.3 million.
We know not everyone will use us. But we're working to help as many people as we can, in every borough, town and county in the UK, save money every time they fill up.
Want to save more? Our tips for saving fuel can cut what you use, as well as what you pay.
Based on: population 383,919 (ONS, mid-2024; via citypopulation.de); 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.
