The firm, founded in 2000 and acquired last month by United Capital, has previously been contracted by Perth and Kinross Council and Angus Council and is now pursuing more work in Tayside.

General manager John Reynolds told The Courier: “It has always been our plan to push more into the east coast and being part of a larger group after our recent acquisition allows that to happen faster.

“Saltire will seek to win public sector contracts through competitive tendering and great customer service, a reputation that we have worked hard to build up.

“We will also roll out a large domestic heating marketing campaign and look at growth by acquiring other east coast operators.”
