The companies, both owned by specialist building services investment group United Capital, have agreed to trade under the McGill name.
The business, which forecasts annual turnover of more than £15m for the coming financial year, is looking to take advantage of market demand for mid-tier contractors offering a broad scope of services.
Alliance Electrical managing director Errol Lawrie, who has run the business for the past 15 years, will be taking over as the managing director of McGill, having fulfilled this role for the past six months and led the combining of the two businesses.
Lawrie commented: “Bringing together McGill and Alliance combines their core strengths and solidifies McGill’s position as a quality, national mid-tier contractor for the long-term.
“We have already seen the fruits of our efforts and we will announce more news in the coming weeks.”
Graeme Carling, chief executive at United Capital, commented: “When we bought McGill, the intention was to create a sustainable mid-tier contractor for the long-term.
“Errol and his team have clear and ambitious targets to expand this part of the business and will do so with the support of me and my team at United Capital.”
The newly merged business and its more than 100 employees will operate from the McGill offices on Harrison Road in Dundee and will continue to deliver trades services across Scotland.
