Summary of the contracting process

National Highways Limited commissioned specialist environmental engineering consultancy for the Lower Thames Crossing (LTC). The work advises the project on achieving a zero-emissions construction site, with construction activities using electric- and hydrogen-powered plant rather than diesel or hydrotreated vegetable oil (HVO). Advice covers the operation and efficiency of plant, energy infrastructure, maintenance and construction methods. The aim is to help LTC’s delivery partners implement this approach, which the buyer describes as unprecedented at scale in the UK. The requirement is therefore focused on practical zero-emissions construction expertise, not general environmental advice. The work supports the Lower Thames Crossing project; no more specific delivery location is stated.

The procurement is complete: National Highways selected Zen In Transition, and the contract is active and signed. The award was made on 10 September 2026; the contract was signed on 22 September 2026 and runs from 22 September 2026 to 31 July 2028. The contract value is €300,000 excluding VAT (€360,000 including VAT). The requirement was procured as a direct award, justified on technical grounds on the basis that only this supplier could provide the required services and there were no reasonable alternatives. There was one lot, marked as suitable for SMEs. No scored evaluation criteria are recorded; the award rationale points to the supplier’s involvement in comparable zero-emissions road projects in Norway and the Netherlands.

For a future requirement of this kind, a credible supplier would need specialist consultancy capability in delivering construction with zero-emissions plant, particularly electric and hydrogen machinery. Relevant experience should extend beyond general decarbonisation advice to the practical operation and efficiency of equipment, energy supply infrastructure, maintenance and construction methods, and to advising delivery partners on implementation at project scale. The selected supplier was identified through engagement with European partners and experience connected to projects using only zero-emissions plant and machinery in Norway and the Netherlands. That precedent indicates the value of demonstrated delivery knowledge from comparable road projects, especially given the buyer’s stated limited UK supply-chain experience. The original process was a direct award on technical grounds, so future competitiveness would depend on evidence of rare, relevant expertise and a record that supports the case for the proposed approach.

Notice Information

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

Paragraph 6 of Schedule 5 of PA2023 is applicable as the following conditions are met in relation to the public contract: (a) due to an absence of competition for technical reasons, only a particular supplier can supply the goods, services or works required, and (b) there are no reasonable alternatives to those goods, services or works. As referenced above there is no experience of delivering LTC'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.
