EIM24730 - Car benefit calculation Step 5, appropriate percentage, 2011/12 onwards:adjustments to appropriate percentage and code letters used for different fuels 

From 2011/12, the arrangements regarding different fuels are significantly simplified:

  • the diesel supplement applies to all diesel-powered cars
  • all ‘alternative fuel’ reductions cease to be available (though the 6% reduction given to type E cars in secondary legislation until 2009/10 is incorporated into primary legislation). See EIM24850 for more on type E cars from 2011/12.

The code letters used to describe the various types of car are also simplified, as the following table illustrates:

Notes

1

the appropriate percentage for type E cars is 0% from 2010/11 to 2014/15 inclusive; thereafter it reverts to the normal appropriate percentage for type E cars, 9%

2

subject to the overall maximum appropriate percentage of 35%

3

from 2011/12, the diesel supplement applies to all diesel cars, including Euro IV diesels first registered before 1 January 2006

4

former type B cars (see EIM24830) have different CO2 emissions figures for different fuels; the lowest CO2 emissions figure can still be used (normally that for gas)
