MEH Alliance

What MEH Alliance does

MEH Alliance is a UK-based joint venture founded in 2019 to deliver mechanical, electrical, and HVAC (MEH) installation services for the Hinkley Point C nuclear power station in Somerset, England. The alliance is structured as a partnership between EDF UK, the project owner, and five tier 1 contractors: Altrad Services, Cavendish Nuclear, Altrad Babcock, NG Bailey, and Balfour Beatty Kilpatrick. MEH Alliance is set to become the largest contractor on the Hinkley Point C site, with a projected peak workforce of 6,000 individuals.

The alliance's core scope encompasses engineering/design, contracts and procurement, manufacturing, construction readiness, site construction, and system completion across the power station's 7,500 rooms. Its technical deliverables include installation of approximately 335km of pipework, 10,000km of cables, 91 mechanical systems, and 143 electrical systems, spanning Nuclear Steam Supply System auxiliary piping, Balance of Nuclear Island and Balance of Plant piping, HVAC systems, and wrapping/insulation/caulking. Materials management is handled through three dedicated Logistics Centres: MLC1 for pipe and supports, MLC2 for BONI/BOP pipe spools (established March 2025), and MLC3 in Weston-Super-Mare for electrical commodities. The alliance has developed proprietary methods including a 20-metre Polar Crane scaffolding solution (2023 NASC Awards finalist) and Phased Array Ultrasonic Testing that reduces radiography exposures by approximately 600,000.

MEH Alliance operates a managed-services revenue model based on project-based contracts negotiated directly with EDF UK through the HPC framework. There is no public pricing disclosure; contracts cover the full project lifecycle. Customer concentration is singular — EDF Energy / Hinkley Point C is the only named customer. The alliance has achieved notable operational milestones including four years of Zero Harm without a lost-time incident, 60,000+ safe working hours on tank construction, and six awards at the 2024 Hinkley Point C Excellence Awards. The organisation is not publicly traded, has no disclosed parent company, and is structured as an independent collaborative entity established specifically for the Hinkley Point C project.

Direct peers

• Altrad: JV partner (via Altrad Services and Altrad Babcock) inside MEH Alliance and a global industrial services group with ~52,000 people across 50+ countries. Comparable because it provides scaffolding, insulation, and mechanical services that MEH Alliance itself delivers on HPC.
• NG Bailey: JV partner inside MEH Alliance and the UK's largest independent M&E and building services contractor. Comparable because it performs commercial and industrial electrical/HVAC installation of similar scale and is one of the five integrated delivery entities inside the JV.
• Babcock International: Parent group related to JV partner Altrad Babcock and a major UK nuclear services provider supporting decommissioning and submarine propulsion. Comparable because it delivers nuclear M&E and support services into the same UK defence and civil nuclear customer base.
• Balfour Beatty: Parent of MEH Alliance JV partner Balfour Beatty Kilpatrick and one of the UK's largest infrastructure contractors. Comparable because it operates in the same UK infrastructure and nuclear construction space and shares workforce and supply-chain resources with the JV.
• Cavendish Nuclear: JV partner inside MEH Alliance and a specialist nuclear services business supporting decommissioning, Continuous at Sea Deterrent, and new-build. Comparable because it provides nuclear-qualified labour and engineering capability that flows directly into MEH Alliance delivery.
• Costain Group: UK infrastructure and energy contractor delivering major projects across nuclear, water, and transport. Comparable because it competes for similar tier-1 MEH/MEP framework positions on UK energy megaprojects.

Broad incumbents

• Skanska: International infrastructure and construction group with a significant UK civils and energy presence. Comparable because it competes for large-scale UK infrastructure megaproject scopes and operates similar alliancing models on complex public-sector projects.
• Bechtel: Global EPC contractor with extensive nuclear new-build credentials including recent US large-scale projects. Comparable because it operates at the same tier-1 EPC scale on complex nuclear programmes and sets the benchmark for integrated MEH delivery on megaprojects.
• AtkinsRéalis: Global engineering services and nuclear consultancy with deep involvement in UK new-build nuclear programmes. Comparable because it operates across the same nuclear EPC and engineering lifecycle and frequently partners with or competes against MEH Alliance partners.
• Jacobs Solutions: Global engineering and nuclear services firm supporting both UK nuclear new-build and US Department of Energy programmes. Comparable because it provides nuclear engineering, programme management, and construction oversight across the same value chain as MEH Alliance.
