HMRC Advisory Fuel Rates From 1 December 2018

Advisory Fuel Rates - December 2018

HMRC have published the latest Advisory Fuel Rates, which take effect from the 1st December 2018.

What are Advisory Fuel Rates (AFRs)?

These AFRs are the recommended reimbursement rates, for employees reclaiming business travel, usually in company vehicles. However, these Advisory Fuel Rates, are also used to calculate the fuel portion of a mileage claim.  This is important when claiming VAT on mileage expenses.

The use of the Advisory Fuel Rates are based on the engine size and fuel type of your car.  And the highest rate is for cars with large petrol engines (22 pence per mile), the lowest rate is for cars with small LPG engines (8 pence per mile).

HMRC update the Advisory Fuel Rates quarterly to take account of changes in fuel prices. The latest rates are shown below and are valid from the 1st December 2018.

Advisory Electricity Rate

As for the last quarter, the Advisory Electric Rate (AER), for pure electric cars, is 4ppm. This is free of tax and National Insurance.

The use of Advisory Fuel Rates in calculating the VAT on Mileage expenses


The HMRC Advisory Fuel Rate can also used to calculate the fuel portion of your mileage claim. Therefore, this is important if you drive your own car for business and your business (or employer) claims VAT on your mileage expenses.

The formula for calculating the VAT on mileage expenses using the Advisory Fuel Rate is:

Fuel portion = advisory fuel rate x business miles claimed
VAT = fuel portion / 6
VAT on mileage = (advisory fuel rate x business miles claimed) / 6

If you want to find out more about claiming VAT on your mileage expenses please see our blog VAT on mileage expenses – how to claim.

Finally, the changes to the current Advisory Fuel Rates are:

  • Diesel engine, over 2000cc, increased by 1p per mile to 14p
  • LPG engine 1400cc or less, increased by 1p per mile to 8p
  • LPG engine 1601cc to 2000cc, increased by 1p per mile to 10p
  • LPG engine over 2000cc, increased by 2p per mile to 15p
