Fuel duty has an unusual history in UK tax policy. Since 2011, successive governments of every political colour have announced planned fuel duty increases in their Budget forecasts, only to cancel or freeze them at the actual fiscal event that followed. A temporary 5p per litre cut introduced in 2022 has been repeatedly extended well beyond its original planned end date. The pattern has become so consistent that the OBR itself documents it as a recurring feature of UK fiscal policy, planned rises that essentially never happen.
The current plan, confirmed in May 2026, breaks from that pattern in a specific way. Fuel duty will remain frozen until September 2026, but a 3p per litre rise is planned for January 2027, followed by RPI uprating from April 2027 onward, meaning fuel duty would then rise automatically each year in line with inflation rather than requiring a fresh political decision every single Budget.
The government has also introduced a "fuel finder" tool designed to help drivers locate the cheapest fuel prices in their area, projected to save the average household around £40 a year, a measure clearly intended to soften the impact of the coming rise.
The fiscal argument for finally allowing fuel duty to rise is straightforward. Every year it stays frozen or cut represents billions of pounds in revenue the Treasury doesn't collect, at a time when public finances are under significant pressure. Cancelling the planned January rise would cost the Exchequer roughly the same amount as the recent VAT cut on domestic electricity, a meaningful sum the government may not be willing to forgo again.
The counterargument is that drivers, particularly those in rural areas with no viable public transport alternative, have already absorbed years of rising costs elsewhere, and a fuel duty rise lands hardest on exactly the households with the least flexibility to avoid it.
