HMRC splits advisory fuel rates for electric cars

28 Aug 2025

HMRC has split fuel advisory rates for electric cars depending on where drivers charge their company cars due to the price discrepancy between home and public chargers.

From 1 September 2025, the single rate for fully electric cars will be abolished and replaced with two different rates reflecting whether a car is charged at home or on a public charger.

The rate will be 8 pence per mile for home charging and 14 pence per mile for public charging. This will replace the current universal rate of 7 pence per mile.

These rates will be reviewed quarterly in line with petrol and diesel advisory fuel rates.

HMRC said: 'The 'Domestic electricity cost per kilowatt-hour' is the Department for Energy Security and Net Zero annually published figure, uprated with the latest estimate of electricity prices from the Office for National Statistics (ONS).

'The 'slow or fast public charge cost per kilowatt-hour' is the Zapmap public charging price index monthly published figure for slow or fast chargers (charging speed less than 50 kilowatts), uprated with the latest estimate of electricity prices from the ONS.

'A higher amount than the advisory rates can be used as long as you can show that the fuel cost per mile is higher. Therefore, if the public charger used is higher in cost per mile than the new advisory rate introduced for public charging, a higher rate can be used as long as you can show the cost per mile is higher.'
