UK Petrol and Diesel Averages for the Week of 28 September
The UK’s latest weekly petrol and diesel averages cover the week beginning 28 September 2026. The Department for Energy Security and Net Zero published the figures on 29 September; they can help motorists compare the national picture with last week, but they are not a quote for any individual forecourt. Check local pump prices before setting an October refuelling budget.
What the latest weekly fuel figures show
The Department for Energy Security and Net Zero’s weekly road fuel prices series was updated on 29 September with average UK retail prices for the week beginning Monday 28 September. The department’s publication provides the current and previous weekly values for petrol and diesel.
Those exact values are not included in the available source evidence here, so they cannot be reproduced reliably in this comparison. Consult the department’s published table for both weeks before using a numerical comparison. No price or week-to-week change should be inferred from the publication date alone.
Compare petrol and diesel using the published weekly averages
The official figures allow motorists to see whether the national average for each fuel rose or fell from the previous week. Use the department’s values to complete this two-column comparison:
| Fuel | UK weekly average retail price |
|---|---|
| Petrol | Check the official table for the week beginning 28 September and the previous week |
| Diesel | Check the official table for the week beginning 28 September and the previous week |
The table is a national benchmark. It does not show the price at a particular station, guarantee that every driver can buy fuel at the average, or explain the reason for a weekly movement. Prices can vary between nearby forecourts, so the national figure is best used for broad context rather than as a local forecast.
Estimate a fill-up from litres and the local pump price
For a practical estimate, multiply the number of litres you plan to buy by the price per litre at the forecourt you intend to use. Convert pence to pounds by dividing the result in pence by 100.
For example, if a driver buys 40 litres at a local price of 150 pence per litre, the calculation is 40 × 150 = 6,000 pence, or £60. This is an illustrative calculation, not a reported UK pump price. Substitute the price displayed at the station and the litres needed for your own estimate.
A smaller top-up can make a useful comparison too: 20 litres at 150p per litre would cost £30. The final amount depends on the local price and litres dispensed, and may differ from a budget based on a national weekly average.
Check nearby forecourts before you refuel
A UK average combines prices across the country. Your actual cost depends on the forecourt you choose, the fuel type and the volume you buy. Comparing nearby stations can therefore give a more useful estimate for an individual journey than applying the national average to every litre.
Check the current price at stations on or near your route, then calculate the cost using your expected litres. For the national comparison, use the Department for Energy Security and Net Zero’s weekly road fuel prices table and compare the week beginning 28 September with the previous week. Those figures describe the reported weekly average; local signs determine the price available to you.
