Autumn Budget 2026: What It Means for Business Fuel Costs

Chancellor John Healey delivered the Autumn Budget on 28 October 2026, at a time when fuel costs are front of mind for almost every business on the road. With diesel passing £2 a litre for the first time this month, all eyes were on what the Budget would mean for fuel duty.

Here is what was announced, what it means for your fuel costs and how to plan ahead.

What Was on the Table

Fuel duty is currently 52.95p a litre on petrol and diesel. It has stayed at that level since the temporary 5p cut was introduced in March 2022.

The cut was due to be phased out from September 2026, but that rise was cancelled and the 5p cut extended to the end of 2026. Under current law, fuel duty would then rise to 55.95p a litre on 1 January 2027 and 57.95p on 1 March 2027, with the government committed to confirming the final rates at this Budget.

Because VAT is charged on top of fuel duty, every 1p rise in duty adds around 1.2p a litre at the pump. A 3p rise in January would therefore add around 3.6p a litre.

Ahead of the Budget, transport groups called for support. The Road Haulage Association asked for help worth 15p a litre, along with a fuel duty rebate for essential users such as hauliers, coach and van operators.

What the Budget Announced

[CONFIRM AFTER BUDGET: one or two short paragraphs on the fuel duty decision. For example, whether the 1 January 2027 rise goes ahead, is delayed or is cancelled, the confirmed rates and dates, and any other measures affecting road transport such as VED, company car tax, HGV levy or EV charging.]

What It Means for Your Business

[CONFIRM AFTER BUDGET: adjust this section to match the announcement. Suggested wording if the January rise goes ahead:]

For businesses running diesel vehicles, a 3p duty rise means around 3.6p more per litre from 1 January 2027, on top of prices that are already close to £2 a litre.

Illustrative example: a business using 1,000 litres of diesel a month would pay around £36 more each month, or roughly £430 a year, from the duty rise alone. A fleet using 10,000 litres a month would pay around £360 more each month.

[Suggested wording if the rise is cancelled or delayed:] The decision gives businesses some breathing space, but fuel remains one of the biggest costs on the road. With diesel still close to £2 a litre and global supply pressures expected to continue into 2027, planning ahead is just as important.

How to Plan Your Fuel Costs

Budget with fixed weekly prices

Fuel cards with weekly fixed prices give you a set price per litre for the week ahead, so a duty change or wholesale price rise does not catch you out mid-week.

Look at wholesale diesel

Some fuel cards give access to wholesale diesel prices, which can help offset rising costs for diesel-heavy fleets. See our diesel fuel cards page.

Keep your VAT records simple

With fuel making up a bigger share of costs, clear records matter. Fuel cards bring every purchase onto one account, making it easier to reclaim VAT. Our guide to fuel cards and tax explains more.

Check your fuel card is still right for you

Networks, pricing and fees vary between cards. Make sure your current card still suits your routes and fuel use. Compare the options on our best fuel cards page.
