Question to the HM Treasury:

To ask the Chancellor of the Exchequer, what (a) fuel duty and (b) other tax treatment is applicable to hydrotreated vegetable oil used in (i) road fuel and (ii) home heating fuel.

Hydrotreated vegetable oil (HVO) is taxed in line with other fuels according to its use.

For fuel duty purposes, HVO is treated as a diesel-equivalent “heavy oil” in the Hydrocarbon Oils Duty Act 1979. When used as a road fuel, it is therefore liable to the standard rate of fuel duty applicable to diesel which is 52.95p per litre. When used for domestic heating, HVO benefits from the rebated duty rate of 10.18p per litre.

For VAT, HVO is subject to the standard rate when used as a road fuel. When supplied for domestic heating, it is eligible for the reduced rate of VAT, subject to the same conditions that apply to other heating fuels, including applicable quantity thresholds.

The Government currently encourages the use of HVO through the Renewable Transport Fuel Obligation (RTFO), which incentivises the use of low carbon fuels and reduces emissions from fuel supplied for use in transport and non-road mobile machinery. The RTFO has been very successful in supporting a market for renewable fuel since its introduction in 2008. Renewable fuels supplied under the RTFO currently contribute a third of the savings required for the UK’s transport carbon budget.
