Free to save. Pay only to save more.

The gap between the cheapest and dearest forecourt in a typical UK town is regularly 8-12p a litre - on a 55-litre tank that's £4-£6 every single fill-up, just for choosing the right station. The free Fuel Checker map shows you live petrol and diesel prices at more than 10,900 UK forecourts, so the basic saving costs nothing.

Paid plans are for squeezing out the rest. Price-drop alerts catch the moment a forecourt near you cuts its price (one alert is free; Light, Plus and Business add more), the Plus 7-day AI forecast tells you whether to fill up today or wait for the weekend, and loyalty-aware pricing folds Clubcard, Nectar and BPme discounts into every comparison so the "cheapest" station really is cheapest for you. A high-mileage driver covering 12,000 miles a year typically spends £1,700-£2,000 on fuel - shaving even 4% off that pays for Plus several times over.

Business is built for people who drive for a living: multi-stop Smart Routes order up to 100 drops for the fastest, cheapest run, mileage exports produce HMRC-ready expense claims in one click, and every driver on the team gets the same live-price advantage. If fuel is one of your top three costs, the plan usually pays for itself in the first week.
