The Disabled Drivers and Disabled Passengers Fuel Grant is regulated by S.I. 635/2015 and provides for payment of a fuel grant based on a the value of excise chargeable per litre rate of fuel. The current value is €0.636 for petrol, €0.535 for diesel and €0.106 for liquefied petroleum gas (LPG) in respect of the mineral oil taxes applying to these products. An annual maximum of 2,730 litres applies in respect of a driver or passenger, and 4,100 litres in respect of an organisation. This grant is designed to reflect the amount of excise on fuel and has been amended to reflect changes in the carbon tax. There are no further plans to amend rates in 2023.
