Today, we have over 50 engineers specialising in 8 different trades, and we are excited for the future of our business.

T.B. Mackay & Son was a local electrical repair company located in Stockbridge, Edinburgh, which started trading in 1936.

In 1992, Mark Milne and Sean Doherty bought T.B. Mackay & Son and expanded the company into gas and plumbing with only 4 engineers. The name was changed to T.B. Mackay Energy Services, and we moved to our present location in Granton House, which was built by our employees. During this time, we achieved a great deal, and were awarded the Domestic & General ‘Total Excellence & Quality Award’ for heating 6 times, for which we commend our fantastic staff.

In 2019, we became a wholly owned subsidiary of Port of Leith Housing Association (now Harbour) and began a rebrand process. We officially changed our name to Harbour Multi-Trades in November 2022!
