Public services group Radway, which operates from factories in Birmingham and Redditch, has extended its range of services with the acquisition of heating and environmental specialist S J Farmer.
The purchase of the Long Eaton-based heating and plumbing contractor increases Radway's penetration into the large scale heating, air conditioning, plumbing and environmental markets.
Chief executive Bill Briggs said: "This transaction effectively extends the range of services we can offer our public sector partners on a nationwide basis.
"We look forward to extending their [S J Farmer] services to our partners and customers nationwide as part of the Radway Group."
Radway, founded in 1965, is one of the UK's leading specialist window and door manufacturers.
The company is a major large-scale contractor to the social housing, healthcare, education and defence sectors and was chosen as the 2005 Contractor of the Year at the Housing Excellence awards.
Radway was advised on the transaction by HBJ Gateley Wareing.
Corporate partner Andrew Madden, who led the transaction team, said: "This is a particularly important transaction for Radway extending its services into new areas and we were delighted to have been able to introduce the buyers and sellers at the outset."
Financial and tax advice was provided by the transaction services team at BDO Stoy Hayward, led by Graham Elsworth and Louise Chubb.
