HM Revenue & Customs has announced updated advisory fuel rates for company cars, effective from 1 December 2024. The revised rates reflect changes in fuel prices for petrol, diesel, and liquefied petroleum gas (LPG), as well as electricity costs for fully electric vehicles. Notably, the advisory electric rate for fully electric cars will decrease to 7 pence per mile. These rates are used to calculate reimbursements for business travel in company cars and to determine the amount employees should repay for private travel. The update maintains the existing engine size categories for conventional fuel types, with rates adjusted based on current fuel prices and vehicle efficiency data. Employers may continue to use the previous rates for up to one month from the date the new rates apply.
