From heating controls and zoning through to pressurisation units and the wider LTHW circuits that connect them, ComGas provides commercial heating services for offices, schools and commercial buildings across Surrey and surrounding counties — surveyed and specified against an agreed scope.
A commercial heating system is more than a boiler. Heat has to be distributed through LTHW pipework, controlled and zoned so different parts of a building are heated appropriately, and kept at the right pressure by dedicated equipment within a sealed circuit. Each of these is a distinct piece of work, and a heating system that has been installed or maintained without proper attention to all of them tends to develop the familiar problems of cold spots, noisy pipework or pressure loss.
ComGas provides commercial heating services for offices, schools, retail developments, care and residential settings and other commercial buildings across Surrey and surrounding counties, working alongside our commercial gas services — including our preserved commercial boiler servicing and heating maintenance programme — and our commercial plumbing services where a project spans more than one discipline.
This hub currently has dedicated pages for Heating Controls and Pressurisation Units. Boiler plant replacement has its own page: commercial boiler replacement. Commercial heating installation, repairs and maintenance, radiant and warm air heating, LTHW systems, expansion vessels and plate heat exchangers are all part of the wider commercial heating scope we cover; ask us about any of these and we will confirm how it is scoped even where it does not yet have its own dedicated page here. If you are looking specifically for our existing commercial boiler servicing and heating maintenance programme, that remains available on its own preserved page.
ComGas Services UK Ltd
Commercial heating services from Farnham, Surrey.
Each service below has its own dedicated page covering scope, process and what to expect. Other commercial heating disciplines are available on request while their dedicated pages are being built.
Zoning and controls installation and upgrades for commercial heating systems, distinct from wider Building Management Systems integration.
Installation, replacement and servicing of pressurisation units maintaining pressure within sealed LTHW heating circuits.
Planned. Professional. Practical.
Alongside the heating controls and pressurisation services on this hub, ComGas has long provided a commercial boiler servicing and heating maintenance programme, on its own preserved page. That programme covers planned servicing and maintenance visits; the services on this hub cover specific heating-system components and upgrades, and can be arranged as one-off projects or considered as part of a wider maintenance relationship.
Where a piece of heating work forms part of a wider project — a controls upgrade identified during a maintenance visit, or a pressurisation unit replacement alongside other plant room work — the same team can bring it together, so the specific component work and any ongoing maintenance programme are properly coordinated.
Existing ComGas customers can use the Customer Portal to access relevant job and service information relating to commercial heating work carried out at their site. The functions and document visibility available depend on the account and contract configuration.
Portal access is for existing ComGas customers. Prospective customers can discuss portal options when scoping a piece of commercial heating work.

Common questions about heating controls, pressurisation units and how they relate to our boiler servicing programme.
Talk to the commercial heating teamNo — that programme remains on its own preserved page and covers planned servicing and maintenance visits. This hub covers specific heating-system components, currently heating controls and pressurisation units, which can be arranged as one-off projects or alongside a maintenance programme.
Yes. Commercial heating installation, repairs and maintenance, radiant and warm air heating, LTHW systems, expansion vessels and plate heat exchangers are all part of our wider commercial heating scope — get in touch and we can confirm how your specific requirement is scoped.
Yes. Heating controls, pressurisation units and other heating work are often part of a wider plumbing or plant room project, and we coordinate the scopes so they are delivered as one sequenced project.
They can. Heating controls specifically zone and manage the heating circuit; where a building has, or wants, a wider Building Management System integrating multiple building services, that sits on its own preserved page, and we cross-refer between the two rather than duplicating either.
Yes, this is common. We discuss access, working hours and any specific operational constraints before agreeing a programme, and sequence heating work to minimise disruption where a building remains in use.
Yes. Alongside individual heating projects, we can discuss an ongoing maintenance arrangement covering heating system components as part of a wider commercial maintenance programme.
Whether it is heating controls, pressurisation units, or a discipline not yet listed on this hub, share what you need and any access or timescale constraints. We can advise on scope before any survey or quotation is arranged.
