How to Compare Local UK Petrol and Diesel Prices

Local fuel prices can differ between nearby forecourts, so a national average may not tell you where to fill up. Use the government’s Fuel Finder to compare listed prices near you, check when each price was updated, and weigh any saving against the extra distance you would drive.

Find nearby forecourt prices with Fuel Finder

Fuel Finder provides information to help drivers compare prices at UK forecourts. Search for your area or the route you plan to take, then compare the petrol or diesel prices shown for stations that are practical to reach. Treat the results as individual listings: a national figure gives wider market context, but does not identify the cheapest option for your particular journey.

A useful comparison starts with the fuel you actually need. Petrol and diesel prices should be assessed separately, and the cheapest listing may not suit your trip if it is far from your route or unavailable when you arrive. A slightly higher price at a forecourt you will pass anyway can be more practical than a lower price that requires a separate journey.

Use this process before deciding:

1. Search Fuel Finder for your location or destination.
2. Select the fuel type you need.
3. Note each relevant price and the time or date it was updated.
4. Compare the station’s location with your existing route.
5. Recheck the listing before setting off if there has been a delay.

Check how recent each price listing is

The update time matters because a listed price may have changed since it was reported. Look for the listing’s update time or date and be cautious about relying on an older entry, particularly when the difference between stations is small.

If two forecourts appear close in price but one listing is older, the comparison is uncertain. Check Fuel Finder again shortly before travelling, especially if you would make a dedicated detour. If the displayed information is unclear, contact the forecourt directly before relying on it. A fresh listing is still information to guide a comparison, not a guarantee of the price at the pump when you arrive.

The Competition and Markets Authority (CMA) publishes work and monitoring related to the UK road fuel market. This is useful for wider market context; Fuel Finder is the tool for comparing individual forecourt listings. Keep those purposes distinct when making a decision: a national market figure cannot tell you what a particular nearby station currently lists, and an older listing may no longer reflect its price.

Work out whether a detour is worth it

A lower price per litre can be outweighed by the cost of driving farther. Consider the extra distance, fuel used on the detour, and whether the route adds time or requires backtracking. If a station is already on your journey, the additional travel cost may be negligible. If reaching it means a separate round trip, include that travel in the comparison.

For a quick estimate, multiply the price difference per litre by the litres you expect to buy, then compare the resulting saving with the cost of the extra driving. For example, a saving of 3p per litre on a 40-litre fill is £1.20. If reaching the cheaper forecourt would use more than that in extra fuel, the detour is unlikely to save money overall.

This estimate depends on your vehicle’s efficiency, traffic, route length and how much fuel you buy. It is a guide to the trade-off, not a precise calculation. A station that is only slightly cheaper may still make sense if it lies along a journey you already need to make; the same price difference may not justify going out of your way.

Choose based on price, freshness and route

Use Fuel Finder as a decision aid rather than ranking stations by price alone. Compare a suitable fuel type, a listing updated recently enough for your plans, and a location that does not add unnecessary miles. The choice matters most when you are considering a dedicated trip: check the listing again near departure and judge the saving against the extra distance before setting off.
