HMRC has today (25th November) published the latest set of Advisory Fuel Rates (AFRs) to be effective or all business journeys on and after 1st December 2009.
As previously notified, the "advance notice" period of one month has been waived to make the rates published more readily based on the fuel prices (and trends) at the start-time.
The new rates can be found at http://www.hmrc.gov.uk/cars/advisory_fuel_current.htm
