Some low-emission vehicles will be eligible for a grant from the government. These grants go towards the cost of buying a new vehicle. The maximum grant is £3,000 for cars and is applied to the cost of the new vehicle at the dealership when you come to purchase. You don’t need to apply for it. The amount you get towards the cost of your new vehicle depends on the category the vehicle is in. You can view the full list of eligible vehicles on the government website.
