Based in West Yorkshire, this company first set up shop in 1992, refurbishing used stairlifts. Twenty years on, the firm now designs, manufactures, fits and services three different kinds of stairlift of its own: a standard straight-railed version, a bespoke stairlift to be used on curved staircases, and a weather-resistant one for use outdoors. Its products are exported worldwide and more than half of the company’s sales are generated overseas, with its main markets being America, Canada, Australia and New Zealand. International sales have grown by 22% a year, from £30.7m in 2009 to £45.5m in 2011.
