Zoning, time and temperature controls, and standalone or BMS-integrated control upgrades — ComGas surveys existing heating controls and specifies improvements for offices, schools, care settings and commercial buildings across Surrey and surrounding counties.
Heating controls decide where heat goes, and when.
Heating controls cover the zoning, time programming and temperature control that determine which parts of a building are heated, and when. This is a distinct scope from a wider Building Management System (BMS), which integrates heating with other building services such as lighting, ventilation and security under one platform; our BMS services sit on their own preserved page, and we cross-link between the two so each intent has its own destination rather than one page trying to cover both.
Many commercial buildings still run heating on outdated or overly simple controls — a single time clock for the whole building, or zoning that no longer matches how the space is actually used after a refurbishment or change of occupancy. We survey the existing controls and heating circuit before specifying an upgrade, whether that is improved zoning, updated time and temperature programming, or controls that integrate with a BMS your building already has or is planning.
ComGas installs and upgrades commercial heating controls for offices, schools, care and residential settings and other commercial buildings across Surrey and surrounding counties, coordinating this work with the wider LTHW circuit, pumps and pressurisation equipment it controls.

Commercial heating controls services
Zoning, time and temperature control, and BMS-integrated upgrades.
We assess the existing controls and heating circuit before specifying an upgrade, whether standalone or integrated with a wider system.
Zoning & Room-by-Room Control
Splitting a heating circuit into zones that reflect how a building is actually used, so occupied areas are heated without unnecessarily heating the rest.
Zoning reviewed against current occupancy and use
Room-by-room or area-by-area control specified where justified
Existing zone valves and wiring assessed before upgrade
Assess how the building is actually used, then specify controls that match it.
We start by understanding how the building is actually occupied and used — which areas are in constant use, which are occasional, and how that compares with the existing zoning and time programming. From there we specify a controls upgrade that matches the building as it is now, rather than assuming the original design intent still applies after refurbishments, extensions or changes in use.
Installation is coordinated with the wider heating circuit — pumps, pressurisation units and any existing BMS — so controls work as part of the whole system rather than as an isolated addition. Once installed, we explain the programming clearly to site staff, so day-to-day adjustments can be made without needing to call us out for routine changes.
Occupancy and use pattern reviewed before specification
Zoning and programming matched to current building use, not original design intent
Coordinated with pumps, pressurisation units and any existing BMS
Standalone or BMS-integrated options considered on their merits
Programming explained clearly to site staff on handover
How the building is used today matters more than how it was designed.
Buildings change use over time — a school hall used only occasionally, offices reconfigured into different departments, or a care setting with rooms in more constant use than others. We consider current occupancy, any existing or planned Building Management System, and the age and condition of existing controls, before specifying an upgrade, so the result reflects the building today rather than its original design brief.
Current occupancy and use pattern assessed
Existing or planned BMS considered before specifying integration
Age and condition of existing controls reviewed
Wiring and zone valve condition checked where relevant
Coordination with heating maintenance visits where relevant
Every controls upgrade is scoped to how the building is used today. We do not specify a standard controls package regardless of occupancy or existing equipment.

Incredible service — problems fixed perfectly once again.
Lee, Paul and the team at COMGAS are fantastic. They arrived on time and got straight to work, quickly identifying the root cause of the plumbing and heating issues I was experiencing.
The problems were diagnosed swiftly, I was kept fully informed throughout, and both issues were fixed with impressive speed and precision.
Having worked in the industry for nearly 20 years, I know how rare it is to find reliable, trustworthy, and genuinely skilled professionals — let alone a team this good.
I joked about it at the time, but it’s true: I had the best shower I’ve ever had in this house after they finished the job — and I’ve lived here for 10 years!
I honestly couldn’t ask for more and can’t recommend COMGAS highly enough.

Lee came out to the school I work in to look at a problem with our heating, he diagnosed the issue and was able to fix it on the spot in a neat and tidy manor. Would highly recommend

I recently used Comgas for a gas and heating service, and I couldn't be more impressed! From start to finish, their team was professional, friendly, and highly knowledgeable. They quickly identified the issue with my heating system and explained everything in detail, offering both short- and long-term solutions.
The technician was punctual and took extra care to ensure everything was running smoothly. I really appreciated their attention to detail and how they made sure to clean up after the work was completed. My home is now warm and cozy, all thanks to their expert service. I highly recommend Comgas for anyone looking for reliable, efficient, and trustworthy gas and heating professionals!

Commercial heating controls FAQs
Questions about commercial heating controls and zoning
Common questions about zoning, time and temperature programming, and how controls relate to a wider BMS.
No. This page covers heating-specific controls and zoning. A wider Building Management System integrates heating with other building services such as lighting and ventilation, and sits on its own preserved page — we can coordinate both where your building has, or is planning, a BMS.
Our building has changed use since the heating was installed — can controls be updated to match?
Yes. This is one of the most common reasons for a controls upgrade. We review how the building is used now against the existing zoning and programming, and specify an upgrade to match current use.
Can heating controls be added if our building doesn't have a BMS?
Yes. Heating controls can be specified as a standalone system without a wider BMS, and can be integrated later if a BMS is added in future.
Will a controls upgrade affect our existing pumps or pressurisation unit?
We coordinate any controls upgrade with the wider heating circuit, including pumps and pressurisation units, so the system continues to work correctly as a whole rather than the controls being treated in isolation.
Can you review our existing controls without committing to an upgrade?
Yes. We survey and test existing controls and explain our findings clearly, and only recommend an upgrade where it is genuinely justified by the condition or performance of what is already there.
Can controls work be arranged alongside a maintenance visit?
Yes. Controls issues identified during a boiler servicing or heating maintenance visit can be scoped and quoted separately, and we coordinate the two so work is sequenced sensibly.
Reviewing your heating zoning, or planning a controls upgrade?
Tell us about the building, how it is used, and any existing controls or BMS already in place. We can advise on the right approach and arrange a survey where appropriate.
