Notes: Mean mpg - miles per gallon - from manufacturers information, weighted by annual sales to businesses (Fleet Audits, 2006). Applied mpg - adjusted downwards by 10 per cent to take account of real driving conditions and lower fuel economy for older cars. For LPG, mpg is assumed to be 20 per cent lower than for petrol due to lower volumetric energy density. Department for Business, Enterprise & Regulatory Reform's latest petrol and diesel prices (26 May 2008), LPG from AA website (May 2008).
Will the rate per mile figures change if fuel prices go up or down?
With effect from the January 2008 change, the rates will be reviewed twice a year. Any changes will take effect on 1 January and 1 July but will be published on the HMRC website about one month in advance (http://www.hmrc.gov.uk/cars/advisory_fuel_current.htm).
HMRC will also consider changing the rates if fuel prices fluctuate by 5 per cent from the published rates when each review is made and HMRC consider the price change will be sustained.
Employers should make themselves aware of any changes by referring to http://www.hmrc.gov.uk/cars/advisory_fuel_current.htm in June and December each year. It is the primary source of information.
VAT
Customs will also accept the figures in the table for VAT purposes though employers will need to retain receipts in line with current legislation.
