New London and UAE offices for McGill owner Graeme Carling, chief executive of United Capital. The owner of Dundee building services company McGill has opened offices in London and the United Arab Emirates. United Capital is currently two years into a five year buy-and-build plan, acquiring building services firms to grow group turnover to £500 million by 2024. The group, run by chief executive Graeme Carling, expects to acquire at least £100 million by the end of the year. ‘It makes perfect sense’ Mr Carling said: “We are already one of the fastest growing businesses in our sector having grown from zero to a £50 million turnover group within 14 months.
