Building Services


Danfoss Schneider Authorised Partner


Formerly Greenstar Building Automation, we've recently evolved our brand to GSTEC to better reflect the broad range of technical services we're able to provide to the marketplace, including:   
  • Building automation
  • Power quality
  • Electrical infrastructure
  • Switchboard builds
  • Lighting and room control solutions
  • Technical supply, engineering and commissioning services
  • Service support.     
GSTEC has proudly served the industry for 35 years and we continue to expand to meet the needs of our growing customer base.    

Whether for Building Management Systems, HVAC control systems, energy monitoring and reduction projects, service and maintenance support, or engineering and auditing services, our focus is on client requirements, rather than the more traditional product-centric approach.
