Our companies make the controllers, the sensors and the software that connect heating, ventilation, lighting and metering into one building management system, then turn the data into decisions. Lower energy bills and fewer breakdowns, with the evidence that auditors and regulators ask for. Everything is built to reduce a building’s carbon footprint without making it a worse place to be.
As CEO of TBT Group, I’m proud to share our commitment to enhancing building efficiency and occupant well-being through our cutting-edge monitoring and control systems. Our mission is clear: to reduce operating costs, elevate comfort levels, and ensure seamless operations for buildings of all types and sizes.

Each installation reports in real time, raises an alert before a tenant notices a fault, and produces the reports needed for compliance. That is where the carbon and energy savings come from. Read more about our research and development.
Our strategy is to grow in IoT-based building services: more sensors in more buildings, feeding the Halo and Tyrrell Analytics platforms, with our own Niagara 4 controllers at the centre.

We have worked in this industry since 1998 and build our products around those pressures: monitoring that runs in real time, reports that write themselves, and IoT integration that gives precise control of every connected system.
