Summary of the contracting process

National Highways Limited commissioned specialist environmental engineering consultancy services for the Lower Thames Crossing. The work supports the project’s ambition to operate as a zero-emissions construction site, using electric and hydrogen-powered plant instead of diesel or hydrotreated vegetable oil. The adviser is expected to help the project and its delivery partners understand how this can be implemented across construction activities at scale, including the operation of plant and machinery, energy infrastructure, efficiency, maintenance and construction methods. The requirement concerns the Lower Thames Crossing site and its construction supply chain. It is classified as environmental engineering consultancy. The procurement was divided into one lot, identified as suitable for small and medium-sized enterprises.

The procurement is complete and the contract was awarded on 10 September 2026 to Zen In Transition, an SME based in the Netherlands. National Highways used a direct award, justified by specialist technical capability and the lack of comparable UK experience. The selected supplier had relevant experience from zero-emission road projects in Europe, including Norway and the Netherlands. The award value is €300,000 excluding tax and €360,000 including tax. The contract period runs from 22 September 2026 to 31 July 2028, with signature scheduled for 22 September 2026. The award was assessed as above the relevant threshold and the stated rationale classification was single-supplier technical reasons.

This requirement indicates demand for specialist advisers who can help major UK infrastructure projects move construction plant away from fossil fuels and operate with electric and hydrogen alternatives. A credible future competitor would need practical knowledge of zero-emission plant and machinery, rather than only general carbon strategy or environmental reporting. Relevant capability includes planning and operating energy infrastructure, improving plant efficiency, designing workable maintenance arrangements and adapting construction methodology to low-carbon equipment. Experience on large road or civil engineering projects would strengthen credibility, particularly where the supplier can show delivery of zero-emission equipment at scale. International experience may be valuable where UK market experience remains limited, and the buyer has demonstrated that a specialist SME can meet this type of requirement.

Notice Title

LTC Zero Emissions Advisory Services

Notice Description

As part of Lower Thames Crossing's ambitions to be a carbon pathfinder project, LTC have a target to be a zero emissions free site from 2027. This means no diesel and no Hydrotreated Vegetable Oil (HVO) allowed in all construction activities by the Delivery Partners and relying only on Electric and Hydrogen powered plant. This is something that has never been done at scale before in the UK and there is very limited understanding within our supply chain for how this can be executed. Although our Delivery Partners are working on how they can deliver this, they have limited experience in the UK and external specialist consultancy is required to advise LTC.

Procurement Information

There is no experience of delivering Lower Thames Crossing's carbon ambitions in the UK but this has been delivered elsewhere in Europe e.g. Norway and Netherlands. Both the Norwegian and Dutch roads authorities have delivered some projects using only zero emissions plant and machinery. This specialist resource has been identified as a result of engagement with European Partners and through their involvement with these European projects are able to advise on the operation of the plant, efficiency, energy infrastructure, maintenance and construction methodology to assist LTC deliver its zero carbon emission objectives.
