Key takeaways
- The Telegraph reported on October 24, 2026 that Chancellor John Healey has drawn up plans for a carbon charge on imported petrol and diesel, to be announced in the Budget on October 28.
- The charge would extend the UK Carbon Border Adjustment Mechanism, which takes effect on January 1, 2027 and currently covers aluminium, cement, fertiliser, hydrogen, iron and steel.
- UK gas prices, meaning petrol and diesel pump prices, are near records: the RAC put petrol at 174.79p per litre on October 9, up 31.6 percent since the end of February.
- Fuel duty is frozen only until December 31, 2026, so the Budget decision on duty is likely to affect drivers sooner than any carbon charge on imports.
Chancellor John Healey has drawn up plans for a “green tax” on imported fuel, which could add to gas prices (the pump price of petrol and diesel) in Britain, according to a report by the Telegraph on October 24, 2026. The measure would be announced in the Budget on Wednesday, October 28, and would extend the UK’s carbon border adjustment mechanism to refined fuel. The proposal has not been confirmed by the Treasury, and it lands while pump prices sit close to record highs.
What is the reported carbon charge on imported fuel?
A carbon border adjustment mechanism (CBAM) is a levy that makes imported goods bear a carbon cost comparable to that paid by domestic producers. According to reports of the Telegraph’s story, Healey is considering a “carbon charge” on refined products, which could include petrol and diesel imports. British refineries currently face net-zero compliance costs that their overseas competitors do not, which allows imported fuel to undercut local output.

The UK scheme is already in law. The Finance Act 2026 received Royal Assent on March 18, 2026 and the mechanism takes effect on January 1, 2027. It covers imports of aluminium, cement, fertiliser, hydrogen, and iron and steel. Refined fuel is not on that list.
Refiners had lobbied on the gap. Industry figures told a Westminster committee that a Treasury decision to exclude refineries initially threatened the viability of the UK’s four remaining sites.
Would the charge raise gas prices for UK drivers?
Not immediately, according to the reporting. Fuel duty is frozen until December 31, 2026, so motorists would not be imminently affected by an expansion of the charge. It is unclear whether the government will extend the freeze into next year.
Opponents argue the cost would reach consumers. John O’Connell, chief executive of the TaxPayers’ Alliance, called the proposal “a shameless tax raid disguised as environmental policy”. Supporters see it differently: Elizabeth de Jong, chief executive of Fuels Industry UK, said that without a level playing field there is both carbon leakage and investment leakage, according to a report citing the i newspaper. The same report said Energy Secretary Miatta Fahnbulleh is reported to support expanding the mechanism.

How high are gas prices in Britain now?
Pump prices are close to records after the US-Iran war began on February 28, 2026. RAC analysis put petrol at 174.79p per litre on October 9, a rise of 31.6 percent from 132.83p at the end of February. Diesel briefly rose above £2 per litre in October.
Official weekly figures for the week of October 12 showed diesel at 200.04p and petrol at 175.28p, according to PetrolPrices.co.uk. The same source said diesel set an all-time record of 200.01p on the RAC’s daily measure on October 2. The House of Commons Library recorded petrol at 174.9p and diesel at 199.5p on October 5, and described the diesel figure as a new record.
The Treasury also gains from higher prices. The RAC Foundation estimates the government has collected about £1.27bn in extra VAT on petrol and diesel since the war began, as cited in the same i newspaper coverage.
Why fuel duty matters more than the carbon charge
The nearer-term pressure on gas prices is fuel duty. The temporary 5p cut introduced in 2022 remains in place. Current legislation raises duty by 3p per litre on January 1, 2027 and again to 57.95p per litre from March 1, 2027, which fully withdraws the cut.

PetrolPrices.co.uk estimates that, with VAT added, this would add about 6p a litre at the pump. The RAC has called for the cut to be extended or for VAT to be reduced. Brit Brief reported on October 25 that a larger cut of 12p a litre is being discussed, though that figure is speculative and has not been confirmed by the government.
Why the fiscal backdrop limits the Chancellor’s room
Healey delivers his first Budget with little margin. RSM’s preview says higher gilt yields and inflation may have roughly halved the £23.6bn of headroom he inherited. Public debt is close to £3tn, and a Reuters poll cited by Admiral Markets put headroom at about £10bn to £12bn.
Markets are focused on credibility. According to the same Admiral Markets analysis, the 30-year gilt yield peaked near 6.05% on October 8, the highest since 1998, and had eased to about 5.83% by October 21. A carbon border measure would also raise revenue or protect industry without a headline tax rise, which is one reason it is attractive in a tight fiscal setting. That motive is an inference, not a position stated by the Treasury.
The UK is not alone in testing its borrowing limits. For comparison, see Intelligence Report’s analysis of French bond yields passing 5% and its look at the Federal Reserve meeting this week.
What to watch
- October 28, 2026: the Budget, expected around 12:30 UK time, with the Office for Budget Responsibility forecast published the same day. Watch whether refined fuel is added to the carbon border mechanism, and on what timetable.
- Fuel duty decision: whether the 5p cut is extended beyond December 31, 2026, or the scheduled 3p rise on January 1, 2027 proceeds.
- Gilt market reaction: the 30-year yield around its recent 5.8% to 6% range.
- October 28 to 29: the US Federal Reserve statement on October 28 and the European Central Bank decision on October 29, which will shape the global rate backdrop.
- November 5, 2026: the Bank of England rate decision, with Bank Rate currently at 3.75%.
- Weekly pump data: government and RAC figures, to see whether diesel stays near 200p per litre.
Frequently asked questions
What is the carbon charge on imported fuel Healey is reportedly considering?
The Telegraph reported on October 24, 2026 that Chancellor John Healey is weighing a carbon charge on imported petrol and diesel. It would extend the UK carbon border adjustment mechanism, which starts January 1, 2027, so imported fuel bears carbon costs similar to domestically refined fuel. The Treasury has not confirmed it.
Will the carbon charge raise UK petrol prices?
Critics, including the TaxPayers' Alliance, say it would feed into pump prices. Reports note fuel duty is frozen until December 31, 2026, so drivers would not be immediately affected. Supporters argue it would stop investment leaving the UK. The final design and timing will only be known on Budget day.
When will UK fuel duty go up?
Under current legislation, fuel duty rises by 3p per litre on January 1, 2027, and by a further 2p on March 1, 2027, fully withdrawing the temporary 5p cut. The Chancellor can change this in the Budget on October 28, 2026, and motoring groups are lobbying for an extension.
