## FAQ

### How much is diesel per litre in the UK right now?

The UK average is 197.4p a litre (£1.97), measured across 1,485 forecourts on 18 September 2026. The cheapest published price is 107.9p and the most expensive is 226.5p.

### How much does it cost to fill up a car with diesel?

A typical 55-litre family car costs about £108.57 to fill at the UK average. A small 40-litre tank costs around £78.96, and a large 70-litre tank around £138.18.

### Why is diesel cheaper in some towns than others?

Pump prices are set forecourt by forecourt, not nationally. The biggest factors are how many competing stations are nearby, whether a supermarket operates one of them, and local delivery costs. That is why dense urban areas with supermarket forecourts are usually cheaper than rural areas, motorway services and remote parts of Scotland, Wales and the South West.

### Where does this price data come from?

Retailers publish their pump prices under the UK government's open fuel price scheme. CheapestFuel collects those feeds, normalises them and shows them on a [map](https://cheapestfuel.uk/map/). The scheme covers Great Britain; Northern Ireland is not included.
