Leading global nuclear engineering group Assystem has acquired Mactech Energy Group (Mactech), a leading UK company recognized for its expertise in construction capabilities for the nuclear industry, with a revenue of c.£16m in 2024.
A strategic investment for the future of British nuclear power
The acquisition is a long-term investment in the UKs nuclear industry workforce ahead of the projected construction of up to 24GW of new nuclear technology in coming decades.
Assystem is making this move to accelerate the construction phase of these nuclear projects that will deliver the country’s goal of low carbon-power by 2030.
Mactech, a key partner for major nuclear projects
Mactech has supported site-based construction activities on UK nuclear sites for over 37 years and their unrivalled network of UK-based skilled resources will reinforce Assystem’s capacity to deliver on the construction aspects of projects in the new build, decommissioning and defence nuclear sectors.
As a well-established player in the nuclear industry, Mactech will continue to support its nuclear industry clients at Hinkley Point C, the Magnox fleet, and on SMR projects.
Founded in 1986 by Kevin McFarlane, Mactech is now operating under the direction of Andrew McFarlane, and following acquisition it will continue to operate as an independent and separate company, retaining its brand, offices, and market position under the ownership of Assystem Holding UK.
I am delighted to welcome Mactech to the Assystem group. Like Assystem, they are driven by a core mission: to accelerate the delivery of nuclear projects and help the UK drive its energy transition. By combining the strengths of Assystem and Mactech, we look forward to supporting our nuclear and defence customers through engineering and construction contracts.
I am delighted to announce that Mactech has officially joined the Assystem family, marking an exciting new chapter in our journey to support the UK’s nuclear energy transition. By joining forces with Assystem, Mactech is better positioned than ever to create meaningful career opportunities and deliver innovative, high-value services to our customers. We are excited about the opportunities this partnership brings and look forward to working together to accelerate progress toward a cleaner, more sustainable energy future for the UK.
