Volumetric Concrete Mobile Plants

Debate between Alistair Carmichael and Tanmanjeet Singh Dhesi

Thursday 22nd June 2023 Westminster Hall

[Mr Alistair Carmichael (Orkney and Shetland) (LD)]

I beg to move,

That this House has considered volumetric concrete mobile plants.

It is a pleasure to serve with you in the Chair, Mr Efford. I place on record my appreciation of the Backbench Business Committee for allowing us time to debate an important, if hopefully not the most contentious, area of political regulation.

We are doubtless all familiar with the sight of large conventional drum mixers carrying concrete around our streets and roads. Those drum mixers operate at 32 tonnes and carry loads of 8 cubic metres to building sites. They carry concrete that has been prepared in a fixed location and then loaded on to the mixers. Drum mixers are the dominant force in the market, and there are something in the region of 20,000 of them.

Volumetric concrete mixers are a much smaller part of the concrete sector but can operate in circumstances in which the conventional drum mixers do not, most notably in rural areas or where smaller batches are required. They can legally weigh up to 44 tonnes on five axles and 38.4 tonnes on four axles. That is at the heart of the matter that I wish to discuss. They deliver concrete to individuals and smaller businesses and mix concrete on site. They are particularly useful for reaching remote areas and tight urban sites, and compared with larger traditional concrete carriers they have a range of other benefits, notably their lower carbon usage.

There is a large element of time-sensitivity at play here. Once mixed, concrete has a shelf life of only two hours, which means that drum mixers must get to their construction site and pour the concrete within that two-hour period or it goes to waste and to landfill. The need for VCMs in rural areas—where there are fewer plants mixing concrete at scale, if indeed there are any at all, and hence longer road journeys to sites—is obvious, but the place of VCMs in the sector goes beyond that. They are particularly useful for emergency road and rail repairs, where the mixer may have to wait around. For a drum mixer, an expensive batching plant must be set up to avoid concrete becoming unusable at the two-hour mark, but VCMs have no such issues, which shows their benefits in such situations.

There is a very real danger that, if the Government’s regulation of the sector gets the balance wrong, the whole volumetric concrete sector could be placed at risk and a small but very important part of the construction industry could be lost, for little discernible benefit.

[Mr Tanmanjeet Singh Dhesi (Slough) (Lab)]

I thank the right hon. Gentleman for securing today’s debate on volumetric concrete mobile plants and for allowing me to intervene. Having worked in the construction industry for about two decades, and having gained a dumper driver ticket to take ready-mixed concrete on a dumper to various parts of the construction site, I could not resist taking part in today’s debate. More to the point, my constituency is home to Mixamate, which is a ready-mixed concrete business. Mixamate highlights to me not only the impact on livelihoods but the environmental and economic damage that policy could create. Does the right hon. Gentleman agree that it is incumbent on the Government to undertake a full impact assessment of current legislation?

[Mr Carmichael]

Had I known that the hon. Gentleman had that level of expertise, I would have had him on the all-party parliamentary group for lower carbon construction vehicles a long time ago. I agree with him. I do not want to reheat old debates, but we are where we are today because there was not a proper economic and environmental impact assessment at the time. I hope the Minister will indicate that the Government are willing to revisit the issue. If we go through the process properly, we will find that there is a better way of dealing with the issue, but I will let the Minister speak for himself.

VCMs operate right across the United Kingdom. Their manufacture and use are estimated to contribute £380 million to the economy and employ more than 15,000 skilled workers. They operate the length and breadth of the country, and in communities such as those that I represent they are of prime importance to the local construction sector. Businesses such as Andrew Sinclair Ltd in Orkney and Tulloch Developments in Shetland tell me regularly about the desperately detrimental impact that the proposed changes will have on them.

Companies with VCMs operate in at least 134 constituencies and are a truly integral part of the country’s construction industry. For almost 50 years, they have operated within a proportionate regulatory environment. Until 2018, VCMs on four axles could run at the manufacturer’s design weight, which is often about 41 tonnes. However, in 2018, the Department for Transport decided to impose a 32 tonne limit for all VCMs, enacted through the Goods Vehicles (Plating and Testing) (Miscellaneous Amendments) Regulations 2017. The limit forces VCM operators to phase out their current VCMs by 2028, replacing them with the 32 tonne model, which is equally expensive but less effective. Lighter vehicles mean more journeys on the road and more carbon emissions as a consequence.

That is despite the fact that Highways England’s 2017 report endorsed the operation of VCMs at about 44 tonnes on five axles and 38.4 tonnes on four axles. That proposal had the support of the then Transport Minister, the right hon. Member for South Holland and The Deepings (Sir John Hayes). To be less than generous, this is a classic example of an obscure regulation changed by civil servants that causes a massive headache for businesses in the real world.
