Budget may consider higher tax on heavier new cars, raising family cost concerns

A new tax on heavier cars could be considered at the Budget, prompting warnings from the Conservatives that families may face higher costs. The proposal has been advocated by clean energy group Transport & Environment (T&E), which argues that large SUVs pose greater risks to other road users, cause more road wear and produce higher emissions.

T&E has proposed a one-off Vehicle Excise Duty supplement of £10 per kilogram for new petrol cars weighing over 1,600kg and electric cars over 2,000kg. Its example suggests the charge would add £1,120 to a petrol Ford Kuga; critics also say it could burden motorists and deter buyers of heavier electric cars. The Treasury declined to comment on speculation, while councils already levy extra parking charges for SUVs in some areas.
