Question to the HM Treasury:

To ask the Chancellor of the Exchequer, whether her Department has conducted modelling since July 2024 on the potential revenue that could be raised from a weight-based system of Vehicle Excise Duty for cars.

Vehicle Excise Duty (VED) is a tax on vehicles used or kept on public roads. Different rates apply to cars, vans, motorcycles and heavy goods vehicles, and the rate for each vehicle is calculated according to a range of factors, such as its date of first registration, weight, or CO2 emissions.

The Government annually reviews the rates and thresholds of taxes and reliefs at fiscal events, and in doing so considers a wide range of factors including complexity, value for money, and administrative burdens for tax payers. The Chancellor makes decisions on tax policy at fiscal events in the context of the public finances.
