Budget on 28 October: what each fuel option would save you at the pump

Chancellor John Healey's first Budget is 11 days away, and drivers are waiting to hear whether fuel duty goes up in January as planned. Nothing has been announced. Here is what has been reported, what has been asked for, and what each option would be worth on a full tank at today's prices.

The short version: duty is due to go up 3p a litre on 1 January and 2p on 1 March. The Financial Times reports that Healey is expected to drop both rises. If he does, that saves £1.98 on a 55-litre fill from January and £3.30 from March, compared with the plan. A 10p duty cut would save £6.60. Each point off VAT would save about 80p on petrol. None of this is confirmed until the Budget.

What is planned now

Fuel duty is 52.95p a litre until 31 December 2026. GOV.UK's schedule, published on 22 May, then has it at 55.95p from 1 January 2027 and 57.95p from 1 March 2027. With VAT, that is 3.6p more at the pump in January and 6.0p more by March.

All else equal, that would take today's UK averages from 174.2p to about 177.8p for petrol and from 199.2p to about 202.8p for diesel on 1 January, and to about 180.2p and 205.2p from 1 March. That is a simple sum, not a forecast: oil prices and retailer margins will move prices in both directions as well.

How Fuel Finder UK helps

How we worked it out

Duty rates are from GOV.UK. Budget expectations are from the press reports linked below and are not confirmed. The pence-per-litre savings add 20% VAT to any duty change, and one point of VAT is 1/120 of the pump price. The 55-litre fill matches the other posts on this site. Prices are the average across forecourts with a price between 100p and 300p in the official Fuel Finder data.

The limits: retailers do not always pass a tax change on in full or straight away, and wholesale prices will move. This shows what each option is worth on paper, not what pump prices will do.
