A key supplier of high-tech home support equipment to local authorities looks set to be sold by its private equity owners. Bridgepoint Capital, which has a raft of interests in the healthcare sector, has revealed it is conducting a strategic review of Tunstall which manufactures home sensors and telecare systems linked to call centres. The review of the company, which City analysts value at up to £600m, was triggered by inquiries of sale from technology giants Bosch and Phillips. Bridgepoint bought Tunstall from another private equity firm, HgCapital, just two years ago for £225m. Interest in home technology has increased because the Department of Health has said it wants to increase the number of people being cared for in their own homes, particularly older people, as a way of reducing its costs. The idea was a key recommendation into the future of health services by City banker Sir Derek Wanless. Bridgepoint has made local authorities a key part of its strategy; it was also behind the buyout of Leeds Bradford International Airport in May from five Yorkshire councils for £145.5m.
