If you’re a UK business looking to cut costs on vehicle fuel, a fuel card can be a smart and efficient tool. But with dozens of options available, how do you know which fuel cards are actually the cheapest?
In this guide, we compare the most cost-effective fuel cards available to UK businesses in 2025. We look beyond just pence-per-litre savings and consider all fees, pricing models, and coverage to help you find the best deal for your business.
What do we mean by cheapest fuel card?
When we refer to the cheapest fuel cards, we’re not just looking at the lowest price per litre. Instead, we’ve assessed:
- Monthly and annual fees, which can quickly add up
- Hidden charges, such as underuse or late payment fees
- Savings per litre, either fixed discounts or access to lower-priced stations
- Coverage – because a card that only works at a few stations can cost you more in the long run
