Industrial services provider Bilfinger has acquired UK-based nZero Group as of May 12, 2025, including the two subsidiaries Orbital Gas Systems Ltd. and Thyson Technology Ltd.
The transaction comprises nZero offices in Ellesmere Port as well as further locations in Staffordshire and Bristol. With around 240 employees, nZero specialises in advanced energy systems and gas technologies. The bolt-on acquisition successfully continues Bilfinger’s strategic course.
The recent transaction allows Bilfinger to expand its footprint in the gas and hydrogen sectors in the UK, leveraging the advanced technology and services of nZero’s expert team. nZero specializes in gas measurement, analysis, and control systems and offers proprietary solutions in clean energy, CO2 quality and quantity measurement as well as digital services and consulting along the whole value chain.
Through its subsidiaries, Orbital Gas Systems and Thyson Technology, the nZero Group has positioned itself as a significant player in the industry. In 2024, nZero generated revenue of approximately £30million (around €35million).
“We are looking forward to welcoming the talented nZero team to Bilfinger,” says Sandy Bonner, president engineering and maintenance UK at Bilfinger.
“This acquisition not only enhances our technological capabilities but also strengthens our commitment to the UK market. By leveraging the combined excellence of both teams, we will deliver innovative solutions tailored to the UK's specific needs. We will be perfectly equipped to support the process industry in meeting the government’s ‘net zero by 2050’ target.”
Integrating nZero’s capabilities will complement Bilfinger’s broad portfolio for UK customers, particularly in Electrical, Instrumentation and Controls (EI&C), while adding to the company’s global expertise in conventional and renewable energies.
“This acquisition marks a further step in the strategic diversification of our portfolio and strengthens our position in the energy sector,” says Thomas Schulz, Bilfinger Group CEO. “Integrating nZero’s complementary expertise puts us at the forefront as solution provider of choice. We are pressing ahead with our strategy to be customers’ No. 1 in enhancing efficiency and sustainability.”
“We are excited to become part of Bilfinger and their journey to drive innovation and sustainability with combined forces,” says Matt Allen, Managing Director of nZero Group. “The integration will facilitate knowledge sharing and enhancing each other’s skills, as Bilfinger and nZero share their strong commitment to employee growth and development.”
The transaction was closed with immediate effect after signing on May 12. The integration phase commences right away and is expected to last up to twelve months, ensuring the nZero team are smoothly incorporated into the Bilfinger organization, following the highest health, safety, environment and quality (HSEQ) standards.
