HM Revenue and Customs (HMRC) has reduced one of the three diesel Advisory Fuel Rates (AFRs).
The rate for diesel cars with an engine size of over 2000cc has reduced from 17p to 16p.
HMRC has also reduced two of the rates for petrol cars. The rate for petrol cars with an engine size of 1400cc or less has reduced from 14p to 13p while the rate for petrol cars with an engine size over 2000cc has been cut from 24p to 23p.
All other rates remain unchanged.
Hybrid cars are treated as either petrol or diesel.
The latest rates, which organisations use to reimburse drivers for fuel used on business journeys, took effect on December 1 and are now available on the gov.uk website rather than the HMRC website.
