Glasgow-based energy services firm Union Technical has secured a place on the inaugural Sunday Times Scotland Fast 50, marking a significant milestone for the fast-growing business.
Founded by Owen Coyle and Michael Sweeney in 2014, the company was recognised among 50 of Scotland’s fastest-growing private firms, each achieving average annual revenue growth of at least 20% over their two most recent financial years.
The latest accolade follows further recognition for the founders, who were recently named Scottish regional winners at the EY Entrepreneur of the Year UK Awards. The honour saw them attend a reception at 10 Downing Street alongside the Chancellor of the Exchequer.
Union Technical has built its reputation on delivering integrated energy efficiency solutions, including insulation, solar panels, heat pumps and heating systems. Initially established to address a gap in the market for a comprehensive retrofit service, the company now works with homeowners, tenants, local authorities, and both social and private landlords across the UK.
Owen Coyle, Founding Director, said the Fast 50 recognition reflected the resilience of the business and its team.
“Being named on Scotland’s first Fast 50 is a moment to be proud of, and it belongs to the whole team. Getting here hasn’t been easy. Government schemes have shifted, funding has stopped and started, and we’ve had to keep the business steady through all of it.
“What keeps us going is the bigger picture. Scotland’s housing stock still needs a huge amount of work to become warmer and cheaper to run, and we’ve built Union Technical to be here for that job long after this list is forgotten.
“That’s why we keep pushing for a longer-term commitment to schemes like ECO. Homeowners, landlords and installers all need certainty to plan properly, and short funding cycles make that harder than it should be.
“Give this sector a stable, long-term framework and firms like ours can get on with the job of making Scotland’s homes fit for the future.”
