Compare UK Fuel Prices Before Your Autumn Drive

Drivers filling up vehicles at a petrol station forecourt in London, United Kingdom.

A cheaper pump price can trim the cost of a long autumn drive, but the UK’s weekly petrol and diesel averages are benchmarks, not live quotes for the station on your route. The Department for Energy Security and Net Zero publishes the national figures; check its latest release, then compare nearby forecourts and include any detour before deciding where to fill up.

Check the latest UK petrol and diesel averages

The government’s weekly road-fuel statistics include average UK prices for petrol and diesel. The figures are useful for tracking the national price level and making a broad trip estimate.

The source page must be checked at publication to report its latest publication date and the petrol and diesel averages for that release. Those current figures are not included here because they have not been verified. Avoid substituting older figures: the series is updated weekly, so a previously reported average may no longer be the latest one.

A national average combines prices across the country. It does not tell you what a particular driver will pay at a particular pump, or guarantee that a station will match the average.

Why a nearby station can charge a different price

Pump prices can vary by station, region, fuel grade and time. A station beside a motorway may have a different price from one in a nearby town, and prices can change after the weekly national figure is published. The displayed price at the forecourt is the relevant figure when you buy.

Use the national average as a reference point, then check current prices for stations you could realistically visit. Compare like with like: petrol against petrol or diesel against diesel, and the grade your vehicle requires. If a station’s price listing is old or unclear, confirm the price before making a detour for it.

Work out whether a fuel detour is worthwhile

Estimate the amount you expect to buy, compare the cost at each station, then subtract the extra cost of driving to the cheaper one. A simple calculation is:

Compare UK Fuel Prices Before Your Autumn Drive

Estimated saving = litres bought × price difference per litre − detour fuel cost

For example, these figures are hypothetical. If you plan to buy 40 litres and one station is 5p per litre cheaper, the fuel would cost £2 less there: 40 × £0.05 = £2. If reaching it adds a 6-mile round trip, estimate the fuel used for those miles and multiply it by the price per litre. At an assumed efficiency of 40 miles per UK gallon, 6 miles uses about 0.68 litres. At an assumed price of £1.50 per litre, that detour fuel costs about £1.02, leaving an estimated saving of roughly 98p.

The result depends on your vehicle’s real-world fuel economy, traffic and route. The example excludes the value of your time and any parking or access costs. If the detour takes you onto slower roads or through congestion, the extra fuel could be higher.

A quick route-planning check

Before setting off:

Check the latest government weekly averages to understand the national benchmark.
Compare current prices at stations close to your route and confirm the right fuel grade.
Estimate how many litres you need; the saving per litre matters less if you buy only a small amount.
Add the detour distance and estimate the fuel it will use.
Choose the cheaper stop only if the likely saving still makes sense for your journey.

For a long drive, the best option may be a convenient station with a competitive current price, rather than the cheapest listing that requires a substantial diversion. Recheck the forecourt price near your stop, since neither a national average nor an earlier listing promises the price you will find on arrival.
