With an annual turnover of over £3.5 million, Alliance delivers multi-trades services to commercial, private and public sector customers.

Graeme Carling, who purchased former Scotland Top 500 construction company McGill after it entered administration in February, confirmed that Alliance will retain autonomy and identity rather than becoming part of McGill.

He said: “We are excited to complete the purchase of Alliance having signalled our plan for growth through acquisition earlier this year. Alliance is a solid and well-performing company with strong management and an expert team.

“The business will operate as it currently does, with the support of our board of directors and team. We currently have a number of other acquisition targets, some of which are already at legal stages and subject to due diligence, should complete in the early stages of next year.”

Alliance Electricals’ managing director, Errol Lawrie, will continue to lead the business, which delivers electrical, heating and plumbing and fire and security services across the East Coast of Scotland.

Errol, who has led the business since 2007, added: “This is a very exciting point in the history of Alliance and this deal signifies the combined effort of our entire team to grow the business to this point.

“The acquisition by Graeme Carling opens up many new opportunities and I am sure under the stewardship of Graeme and his board of directors, Alliance will continue to grow.”

Alliance Electrical, which will celebrate its 25 year in business next year, operates from its headquarters in Forfar and has over 50 employees.
