Fuel duty rates for petrol and diesel, 2026 to 2027
HMRC, 22 May 2026: the measure “will extend the temporary 5 pence per litre (ppl) cut in the rates of Fuel Duty … until 31 December 2026” and “The legislative default will be for rates to return to the levels set at Budget 2025 from 1 January 2027, but the government will confirm final rates at Budget 2026.”
| Period | Rate | Change from now |
|---|---|---|
| Before 23 March 2022 | 57.95p | – |
| Now (to 31 December 2026) | 52.95p | – |

- Budget 2025 had planned three steps: 1p on 1 September 2026, 2p on 1 December 2026 and 2p on 1 March 2027. The May 2026 change replaced the first two with one 3p rise on 1 January 2027. HMRC: Fuel duty rates 2026 to 2027 (Budget 2025).
- VAT: “You also pay standard rate VAT at 20% on most fuel” (GOV.UK). HM Treasury: “VAT is charged at the point of sale, as a percentage of the pump price (including fuel duty).” So a 20% VAT charge applies to the duty too. GOV.UK: Fuel Duty; HM Treasury: Road fuel review.
- LPG and road fuel natural gas have their own rates per kilogram, and red diesel and other rebated fuels have lower rates; this calculator covers the main petrol and diesel rate only.
