Summary of the contracting process

National Highways Limited procured works to divert Cadent Gas’s HP6 and HP8 high-pressure gas mains, together with associated protection and assurance works. The purpose is to enable the Lower Thames Crossing road development. The requirement sits within gas supply mains construction work (CPV 45231221), with the awarded works also classified as construction work for tunnels, shafts and subways (CPV 45221200). Delivery is for the Lower Thames Crossing scheme and involves infrastructure operated by Cadent Gas. The buying organisation is National Highways Limited, the UK public authority responsible for the road development. The scope is therefore suited to businesses involved in high-pressure gas-main diversion, protection, construction interfaces and technical assurance for major road or tunnel infrastructure projects.

The procurement is complete and has been awarded through a direct award. National Highways stated that only Cadent Gas could execute the works, citing single-supplier technical reasons. The contract was awarded to and signed with CADENT GAS LIMITED on 26 August 2026. The awarded value is £45,954,392 excluding VAT, or £55,145,270.40 including VAT. The contract period runs from 7 September 2026 to 31 March 2031. The requirement was above the relevant threshold and comprised one completed lot. The award covers the diversion, protection and assurance works for the gas mains associated with the Lower Thames Crossing. The selected supplier is a large organisation, and the award status is active.

This award demonstrates demand from National Highways for specialist utility diversion work connected with major transport infrastructure. A future competitor would need credible capability in high-pressure gas-main diversion, protection and assurance, including the ability to work around road, tunnel or shaft construction interfaces. The buyer’s stated rationale shows that technical control of the relevant gas network and the ability to execute these works were decisive: Cadent Gas was treated as the only supplier able to perform them. Businesses targeting similar requirements would therefore need strong evidence of asset-specific knowledge, infrastructure safety competence, assurance arrangements and capacity to deliver a substantial, multi-year package. The opportunity is particularly relevant to gas network operators, specialist utility contractors and firms supporting complex transport schemes.
