Balfour Beatty WorkPlace has bought building services controls firm Colledge Trundle and Hall (CTH) for £2.85m.
Formerly known as Haden Building Management, Balfour Beatty WorkPlace has bought the design and installation specialist of energy control systems, to expand its service offering in energy management.

CTH, based in Worcester Park, Surrey, operates in several markets that complement Balfour Beatty WorkPlace's business. Its customers include DEFRA, Sainsbury's and the University of Cambridge and it is working on a number of PFI schools projects.

Balfour Beatty WorkPlace has an annual revenue in excess of £400m and was re-branded in November to reflect its position as a total facilities management provider.

Ian Tyler, Balfour Beatty chief executive said: 'I am delighted to welcome CTH to the Balfour Beatty Group. This acquisition further strengthens the energy management capability available to our customers.'
