How to find the cheapest fuel in the UK
Across the UK the price per litre can differ by 15p or more between nearby forecourts. On a 50-litre tank that is over £7 every fill-up, so knowing where to look is the easiest way to save hundreds of pounds a year.
Refil shows the cheapest station for your car's fuel around you on a map and highlights the best option in green, so you decide at a glance.
| Fuel | Cheapest | Dearest | Saving/L |
