The question

To ask the Secretary of State for Transport, what assessment her Department has made of the potential impact of banning on 5-axel 44 tonne volumetric concrete mixers on (a) UK manufacturers, (b) road miles, (c) road wear and (d) levels of pollution.

Answered by Keir Mather

The Department ran a call for evidence from October to December 2023 seeking views on three potential options on weight limits for volumetric concrete mixers (VCMs). The outcome of this review was published on 18 March 2025. This can be found at the following link: https://www.gov.uk/government/calls-for-evidence/volumetric-concrete-mixers-review The following factors were considered: reduction in payload per journey, increased waste, and increased vehicle mileage.

Some VCM operators have argued that heavier VCMs could reduce overall trips and emissions, however, the increased road and bridge damage would result in more frequent repairs, offsetting these potential benefits.

As part of its consideration of the evidence, the Department for Transport also assessed the potential environmental impacts in accordance with the Environment Act 2021 which requires Ministers of the Crown to have ‘due regard’ to the environmental principles policy statement when making policy.
