These rates apply to all journeys on or after 1 September 2013 until further notice. For one month from the date of change, employers may use either the previous or new current rates, as they choose. Employers may therefore make or require supplementary payments if they so wish, but are under no obligation to do either.

HMRC will also accept the figures in the table for VAT purposes though employers will need to retain receipts in line with current legislation.

The rates will be reviewed again prior to the next quarter, with any changes taking effect on 1st December

Engine size              Petrol       Diesel      LPG

1400cc or less          12p          11p         8p

1401cc to 2000cc      15p         11p        10p

Over 2000cc             21p         16p        14p

The latest rates show some increases for petrol engines of all sizes, with the rate having gone up 1p here. The rates for LPG engines of all sizes have also gone up, by between 1 and 2p. However, in the case of diesels, it is only the larger engines over 2000c that have gained an increase.

HMRC adds that 'Employers may therefore make or require supplementary payments if they so wish, but are under no obligation to do either.'

The new rates are effective until 30 November 2010. For one month from the date of change, employers may use either the previous or new current rates, as they choose.
