Changes to company car mileage rates

  • New rates come into effect on September 1
  • Selective petrol and diesel rates rise by a penny
  • LPG rates reduce by up to 2p

It’s that time again - HM Revenue and Customs (HMRC) has reviewed the current Advisory Fuel Rates (AFRs) and there are changes for some petrol, diesel and LPG cars.

Starting on September 1, LPG rates have been reduced, while selective diesel and petrol engines have risen by 1p.

The reimbursement rate for diesel engines from 1,601cc to 2,000cc has gone up by a penny to 15p per mile, counteracting the reduction seen in May. Rates for diesel engines below 1,601cc and above 2,000cc remain unchanged.

Petrol engine rates see two changes - engines between 1401cc and 2000cc increase from 17p per month to 18p, while cars with engines over 2,000cc go from 25p per month to 26pc.

LPG on the other hand sees reductions for engines above 1400cc, falling 1p if between 1401cc and 2000cc and by 2p if over 2000cc.

AFRs are set by the Government and reviewed four times a year. These figures are recommended as a guideline for companies to set for their drivers when claiming back business miles. Although companies do not have to follow these guidelines, most do.

See the full list of new mileage rates below.

The AFRs will be reviewed again for December 1.
