An internal Government impact assessment discusses a planned pay-per-mile road tax associated with Labour’s road policy, indicating it will affect a large number of vehicles and could have significant effects on some businesses. The assessment says the levy is intended to support efforts to meet Net Zero targets and estimates it will apply to around 5.6 million vehicles. It also states that the impact of the policy “will be material” for some firms, implying uneven costs across sectors and operators depending on vehicle use and mileage. The reporting frames the analysis as an acknowledgement by ministers that the scheme may increase operating costs for businesses that rely on frequent road travel. Details such as the final structure of the charge, implementation timeline, and how impacts would be mitigated are not included in the provided excerpts. The summary of the internal assessment is the central point across the sources, focusing on scale of coverage and the stated likelihood of meaningful business impact.
