The business was created in 1961 by Gordon Thrussell as a central heating installation business and has continued to grow year on year, now directly employing over 200 personnel. A subsidiary company, Swiftheat (Contracts) Limited, was formed in December 1977 to deal with large contract work, followed in 1990 by the acquisition of Hale Construction (Contracts) Limited, which expanded our areas of operation into construction and renovation of domestic and commercial properties. Some six years later, a further company, Swiftheat Gas Services Limited was created to specialise in gas servicing for the Local Authority Market. Due to our commitment to quality, customer service and our proactive approach under managing director Peter Thrussell we expanded rapidly in this market growing our extensive client base and building partnerships which exist to this day. In 2000 TSG Building Services plc was created to allow the company to tender for large contract work within the social housing and commercial sector.

Gas Servicing & Maintenance - for both Commercial and Domestic Central Heating Systems
Mechanical Installations – for both Commercial and Domestic Central Heating Systems
