The takeover deal will see the firm, which supplies ventilation systems to nuclear power stations, hospitals, airports and offices, change its trading name to Hargreaves Ductwork.

Details of the deal have not been revealed but the firm turns over around £20m and employs 200 staff.

Senior’s chief executive Mark Rollins said: “I am very pleased to announce the disposal of Hargreaves to M+W and to wish the management and employees of Hargreaves all the very best for the future with their new, and more logical, owners.”

Peter Greenhalgh, chief executive of M+W UK said: “We are very happy to have concluded the acquisition of Hargreaves.

“The Hargreaves team have a long history and extensive experience in technology based projects, which fits well with our strategic plans for sustained growth in our target markets of science and research, technology manufacturing facilities and energy-based programs.”

Stuttgart-based M+W is a privately-owned global engineering, construction and project management company, which boasted sales of 2.5bn euros last year and employ 7,000 staff.

One member of the Hargreaves team told the Enquirer: “Most people are positive about the move. There is a view the new owners will bring German manufacturing know-how and long term investment.”
