eVED rates from HM Treasury’s policy paper (13 July 2026); they rise with CPI from 2029 to 2030, and no later rate has been published. Petrol fuel duty at 57.95p a litre, the rate from 1 March 2027 (HMRC); GOV.UK has not published the rate for April 2028.

Plug-in hybrids also pay fuel duty on the petrol they use, which is not included here.

The Autumn Budget is on Wednesday 28 October 2026.

It could. If GOV.UK’s Budget documents change the eVED rates or start date, this page adds an “Announced on 28 October” section that day and shows the new figures.
