TL;DR

On **28 September 2026**, the RAC reported that average **UK diesel** reached a then-record **199.18p per litre**. **Petrol** was about **174.13p** a litre and still rising. Wholesale oil and geopolitics sit outside any driver’s control. Habits that quietly multiply the bill do not.

**Update, 21 October 2026:** this record has since been beaten. The RAC's own daily average passed it on 2 October 2026, reaching [200.01p](https://www.rac.co.uk/drive/news/fuel-news/diesel-price-hits-record-high/). In the government's weekly figures, diesel averaged **200.04p a litre** in the week of 12 October 2026, the highest in the [DESNZ weekly road fuel prices](https://www.gov.uk/government/statistics/weekly-road-fuel-prices), which go back to 2003. For the latest figures and what pushed inflation to 3.5% in September, read [UK fuel prices and inflation: diesel hits a record 200p](https://motorbook.uk/articles/uk-fuel-prices-inflation-september-2026/).

**Update, 5 November 2026:** diesel averaged **198.4p** on 3 November 2026 ([Motorbook November fuel index](https://motorbook.uk/fuel-index/2026-11/)), still close to the 200p record, with ongoing fuel price updates in [UK fuel prices and inflation: diesel hits a record 200p](https://motorbook.uk/articles/uk-fuel-prices-inflation-september-2026/) and that index.

## Beats previous record

On 28 September the diesel average edged past the previous high of **199.09p** from June 2022. RAC head of policy Simon Williams called it “new uncharted territory” and a financial blow to households and businesses that use their vehicles regularly.

Since **28 February 2026**, diesel has risen by about **56.8p a litre** (nearly **40%**). Filling a typical family diesel car now costs almost **£110**, about **£31** more than at the start of the US/Iran conflict. Petrol is up about **41.3p** a litre over the same period.

Williams said the record “spells pain not only at the pumps for drivers, but for everyone who buys goods or services that rely on diesel lorries and vans.” Higher haulage costs tend to pass through to consumers. Pump relief needs a sustained lower oil price over weeks, not days.

## Who feels it most this week

Diesel drivers feel the fill first. Van and lorry operators feel it next, which is how shelf prices and delivery charges catch everyone else. Even petrol drivers are still watching a climbing average.

You cannot unwind wholesale oil from the driveway. You can stop stacking avoidable costs on top: overpaying at the nearest pump, sleepwalking into insurance auto-renewal, missing MOT or tax deadlines, or skipping simple pre-test checks that turn into retests.

## What you can control this week

- Check local pump prices before you fill, not after. In the Motorbook app you can see fuel prices near you, so you can pick a cheaper forecourt before you uncap the tank. Google Maps now shows prices too: see [fuel prices on Google Maps: what UK drivers need to know](https://motorbook.uk/articles/fuel-prices-google-maps/).
- Open insurance quotes if renewal is within the next month or so.
- Walk the car for bulbs, tyres, wipers and warning lights if an MOT is due soon.
- Confirm MOT and tax dates so a fine does not join the fuel bill.

**Check local fuel prices with the Motorbook App** When pump headlines are loud, quiet admin failures still sting. **Motorbook** is on the [App Store](https://apps.apple.com/gb/app/mot-tax-service-log-motorbook/id6802884808): check local fuel prices near you, get MOT and tax reminders from official UK data, and keep a private on-device garage. **No account.
