Building Management Systems & BMS Controls

Installation, upgrades, maintenance and fault finding for building management and plant-control systems, including Trend BMS and Tridium Niagara-based platforms, for commercial properties across Surrey and surrounding counties.

  • BMS installation & upgrades
  • Survey-led scope
  • Planned maintenance options
  • Mechanical & electrical coordination
  • Trend & Tridium Niagara
Building controls in context

Your BMS should make the building easier to understand and maintain.

A building management system can bring visibility and control to heating, ventilation, air conditioning and other connected building services. When alarms are unclear, controls no longer reflect how the building is used, or faults cross mechanical and electrical boundaries, finding the right starting point can be difficult.

ComGas installs, upgrades and supports building management and plant-control systems, including Trend BMS and Tridium Niagara-based platforms, helping commercial buildings manage heating, ventilation, plant and associated controls from a coordinated system. We start with the installed system, the equipment it serves and the outcome you need, then agree a practical scope before any work proceeds.

In practice a BMS monitors and controls equipment such as commercial boilers, heat pumps, pumps, air handling units, ventilation systems, heating circuits, valves and actuators, temperature sensors, time schedules, alarms and energy monitoring. Bringing these together means plant can be scheduled, sequenced and coordinated as one system rather than each item running independently.

BMS installation, upgrades and support

Installation, upgrades and support for the controls that run your building services.

The right scope depends on the installed controls platform, connected plant and available records, so we survey first and confirm the approach before work starts.

System Review & Fault Support

A structured first look at the reported issue, available controls information and connected building services.

  • Existing installation and issue reviewed
  • Available alarms and records considered
  • Mechanical and electrical causes assessed
  • Next steps agreed before further work

Planned BMS Maintenance

BMS checks can be included within an agreed planned-maintenance scope alongside the plant and services being controlled.

  • Checks agreed for the installed system
  • Controls considered alongside connected plant
  • Findings recorded after attendance
  • Further work quoted separately where required
Find out more

Heating, Plant & HVAC Controls

Controls support coordinated with the heating, plant-room, ventilation and air-conditioning systems they serve.

  • Heating and plant controls context
  • Ventilation and HVAC interfaces
  • Occupied-building constraints considered
  • Relevant service teams coordinated
Find out more

BMS Upgrades & Optimisation

Controls upgrades, replacement controllers and system optimisation, scoped once the existing system, objective and platform constraints are understood.

  • Survey before any recommendation
  • Scope and responsibilities made clear
  • Electrical work coordinated where needed
  • Commissioning and optimisation on completion
Find out more

BMS Installation & Integration

New building management and plant-control systems installed, or existing controls extended and integrated with the mechanical plant they serve.

  • New BMS and control panel installation
  • Integration with existing control platforms
  • Control wiring, containment and power supplies
  • Commissioning, testing and handover

Controls are assessed in the context of the plant and services they operate.

How we approach BMS work

Start with the installed system, the connected plant and the outcome you need.

BMS issues do not always begin in the controller. A reported controls fault may relate to a sensor, actuator, electrical supply, communications path, mechanical plant condition or an operating setting. We review the controls and the building services around them before recommending a course of action.

We work with Trend BMS and Tridium Niagara-based platforms, and can also work with and integrate other existing BMS and control platforms where appropriate to the site and project requirements. Where a platform needs manufacturer-specific software or credentials, we confirm that at survey so the proposed scope stays clear and avoids unnecessary changes to a live building system.

BMS projects often include associated electrical work such as control wiring, containment, local power supplies, isolators and connections between control panels and mechanical plant. As an M&E building services contractor, ComGas coordinates these elements as part of the wider installation rather than leaving them split between separate trades.

  • Installed platform and available information reviewed
  • Connected mechanical and electrical services considered
  • Site access and operational constraints discussed
  • Controls platform requirements confirmed
  • Agreed scope confirmed before work
  • Findings and next steps recorded
  • Commissioning, optimisation and handover
Arrange an Initial Discussion
Planned maintenance

Include BMS checks within a joined-up maintenance plan.

Where suitable for the installed system, controls checks can sit alongside planned maintenance for heating, ventilation, air conditioning, plant rooms and commercial electrical services.

  • Scope tailored to the existing installation
  • Visits coordinated with connected plant maintenance
  • Recorded findings and identified actions
  • Further investigation or remedial work agreed separately
Discuss a Maintenance Contract

Coverage depends on the controls platform, system condition and site information available. We confirm the proposed scope before attendance.

BMS questions

Common questions about BMS support

The installed platform and connected equipment shape every scope, but these answers explain our starting point.

Talk to the ComGas team
Can you support an existing building management system?

We can review an existing system, the connected building services and the issue or maintenance objective. The support available depends on the installed controls platform, system condition, access and available records, so we confirm the scope after an initial discussion or survey.

Do you work with every BMS manufacturer or controls platform?

We work with Trend BMS and Tridium Niagara-based systems, and can also work with and integrate other existing BMS and control platforms where appropriate to the site and project requirements. We do not claim blanket coverage of every manufacturer: where a platform needs manufacturer-specific software or credentials, we confirm that at survey and agree the approach before proceeding.

Can BMS checks form part of planned maintenance?

Where appropriate for the installed system, controls checks can be included within an agreed maintenance scope alongside the heating, ventilation, air-conditioning, plant-room or electrical equipment being controlled.

Can you investigate heating or ventilation problems that may involve the controls?

Yes. We can assess the issue across the controls and the connected mechanical or electrical services, helping establish whether the next action sits with the controls, plant, field equipment or another part of the installation.

What information is useful before a BMS visit?

Any available system details, controls drawings, previous reports, alarm information, photographs and a clear description of the issue are useful. We will also ask about access, operating hours and any essential services that must remain available.

Do you install new building management systems, or only maintain existing ones?

Both. We install and upgrade building management and plant-control systems as well as maintaining them. At Lowther Primary School in Barnes we carried out a complete replacement of the building management system, installing Trend IQ4 controls with a touchscreen interface alongside a new heat pump, replacement heating distribution and associated electrical upgrades. At Loseley Fields Primary School in Godalming we completed heating distribution refurbishment, controls and plant-room alterations.

Planning BMS work or supporting an existing system?

Tell us what system is installed, what it controls and the outcome you need, whether that is a new installation, an upgrade, planned maintenance or a fault. We can advise on the appropriate next step and arrange a site survey where needed.
