What environmental impact assessment she has carried out ahead of a decision on whether to ban volumetric concrete mobile plants in 2028.

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 my department’s review into volumetric concrete mixers was published on 18 March. This can be found at the following link: https://www.gov.uk/government/calls-for-evidence/volumetric-concrete-mixers-reviewWhilst some VCM operators have argued that heavier VCMs could reduce overall trips and emissions, the increased road and bridge damage would result in more frequent repairs, offsetting these potential benefits.VCMs will continue to be permitted on our roads, but as planned, a temporary weight limit exemption for this type of vehicle will end on 31 March 2028. This is not a ban or change in policy.

What estimate she has made of the annual additional lorry miles on concrete deliveries that would rise from cutting the weights of volumetric concrete mobile from 2028.

A call for evidence ran from October to December 2023 seeking views on three potential options on weight limits for VCMs. The following factors were considered: reduction in payload per journey, increased waste, and increased vehicle mileage.Information received did not provide any compelling evidence for permitting a weight limit exemption specifically for VCMs on the grounds of increased lorry miles. Current exemptions to weight limits for VCMs will expire in 2028. This policy is being maintained.
