Company History

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.

TSG now boasts the following Divisions:

• Gas Servicing & Maintenance - for both Commercial and Domestic Central Heating Systems
• Mechanical Installations – for both Commercial and Domestic Central Heating Systems
  
• TSG Electrical – Testing and Rewires to Social Housing properties.
  
• TSG Construction – Reactive Repairs, Property Refurbishments & Decent Homes Work to Social Housing Domestic and Commercial Property
  
• TSG Renewable Energy – Servicing, Maintenance and Installations of Solar PV, Solar Thermal, Biomass, Air Source & Ground Source Heat Pumps
  
• TSG New Build – Construction Developments for Social Housing Groups

2021 has now seen TSG Building Services turnover £43m making the business big enough to cope with all range of contracts but accountable at all levels including the directorship for all works carried out on Customers property.

TSG benefits from longstanding existing relationships with a diverse customer base within the Social Housing arena and long-term framework arrangements. A frontrunner in understanding Central Government Funding for fuel poverty in Warm Homes and Eco. As a result, TSG has secured multi-million-pound funding for its clients to reach fuel poverty properties.

Today TSG is still a family owned and run business, operating from its Head Office in Potters Bar, servicing contracts and clients throughout the United Kingdom.

Adam Thrussell is the Chief Executive Officer & Owner of the company making him the 3rd generation of the Thrussell family to continue the ethos and values of the business.
