BMS and Controls
Fault finding, repair and upgrades to building management systems and HVAC controls.
Gas Safe and Refcom registered
Planned and reactive maintenance
What’s included
Done once. Done right.
Controls fault finding
Sensor and actuator replacement
Time and setpoint adjustments
Controls upgrades
Building management systems only save energy when they work. We diagnose control faults, replace sensors, actuators and valves, and adjust time schedules and setpoints so heating, cooling and ventilation run when they should and not when they shouldn’t.
Controls that run the building the way it was designed
A building management system only saves energy and keeps occupants comfortable while its sensors, actuators and schedules are right. Over time setpoints drift, sensors fail and overrides get left on, so heating and cooling run against each other or outside hours. Our controls engineers put that right.
We fault-find and repair Trend, Siemens, Honeywell, Schneider Electric, Tridium Niagara and Johnson Controls systems, replace Belimo, Siemens and Sontay sensors, valves and actuators, and work on standalone controls from Danfoss, Honeywell and Drayton. Where a system has no support contract we can take it on and keep it running.
What a controls visit covers
Fault finding on BMS outstations and field devices
Sensor, actuator and control valve replacement
Time schedule, setpoint and optimiser review
Alarm review and clearing of nuisance alarms
Checking plant is running to its design strategy
Small upgrades, head-end access and remote monitoring
Controls as part of your maintenance
Controls faults often look like heating or cooling faults. Because our mechanical, electrical and controls engineers work for the same helpdesk, we diagnose the real cause rather than passing the job between contractors. Seasonal reviews of schedules and setpoints are an easy win on energy bills and are logged in Simpro with the rest of your PPM.
We support building controls in schools, offices, courts and public buildings across London, the South East, East Anglia and the Midlands.

Why it matters
The right engineer.
First time.
01
Controls that match how the building is used
Badly set or ageing controls waste energy and hide faults. We validate, repair and upgrade BMS and local control panels so plant runs when and how it should.
02
One point of contact
Our helpdesk logs every job in Simpro, so you always know who is attending and when.
03
Every job documented
Photos, job sheets and certificates are sent on completion for your compliance records.
