HMRC announces December AFR update

Date: 23 November 2018   |   Author: Sean Keywood

The latest advisory fuel rates (AFRs) have been published by HMRC, with a rise for cars with bigger diesel engines.

Following the update, the rate for diesel cars with engines bigger than 2000cc will be increased by 1 pence per mile (ppm). 

For cars powered by LPG (liquid petroleum gas), all rates have been increased:  by 1ppm for those with engines smaller than 1400cc and between 1401cc and 2000cc; and 2ppm for engines larger than 2000cc.

All other rates are unchanged, including for petrol cars.

The advisory electricity rate for fully electric cars, first introduced in September, remains at 4ppm.

Hybrid cars are treated as either petrol or diesel cars.

Despite a campaign by fleet operator organisation ACFO, no seperate rates for plug-in hybrids have been announced.

The rates apply from 1 December, however employers can use the previous ones up to one month after that date.

The new rates are as follows:


  • 1600cc or less: 10p (no change)
  • 1601cc to 2000cc: 12p (no change)
  • Over 2000cc: 14p (up by 1p).


  • 1400cc or less: 12p (no change)
  • 1401cc to 2000cc: 15p (no change)
  • Over 2000cc: 22p (no change).


  • 1400cc or less: 8p (up by 1p)
  • 1401cc to 2000cc: 10p (up by 1p)
  • Over 2000cc: 15p (up by 2p).


  • 4p.
