A plant room brings gas, heating, plumbing, electrical and controls systems together in one space — ComGas surveys, specifies and coordinates plant room design input, installation and refurbishment for offices, schools and commercial buildings across Surrey and surrounding counties.
A commercial plant room typically holds boilers or other heat sources, pumps and pressurisation equipment, pipework distributing heat and water around the building, and increasingly the controls or building management equipment that ties it together. When these are installed or refurbished without proper coordination between disciplines, the result is a plant room that is difficult to maintain, awkward to access, and harder to alter later without disrupting everything else in the space.
This page covers the multi-discipline plant room service — surveying an existing plant room or planning a new one, specifying the layout and coordinating mechanical, electrical and controls trades so the finished space works as a system rather than a collection of separate installations. It is distinct from the gas-installation-led plant room work covered within our Commercial Gas services, which focuses specifically on gas pipework and appliance installation; we cross-refer between the two rather than duplicating either, and can coordinate both scopes as one project where your plant room work involves both.
ComGas provides plant room services for offices, schools, retail developments and other commercial buildings across Surrey and surrounding counties. Where your project already has an appointed M&E consultant or design team, our role is to coordinate installation against their design; where no separate design exists, we specify the plant room layout and installation within the scope agreed with you.

Commercial plant room services from Farnham, Surrey.
Whether it is a full new plant room or a refurbishment of an existing space, we assess what is already there and how the disciplines involved need to work together.
Surveying an existing plant room or planning a new one, and coordinating mechanical, electrical and controls trades within an agreed layout.
Refurbishing or replacing plant within an existing room, sequenced to minimise disruption to the rest of the building.
Installing gas, heating, plumbing, electrical and controls elements of a plant room as one coordinated project.
Commissioning the completed plant room across all disciplines and confirming the scope delivered.
Planned. Professional. Practical.
We start by surveying the existing plant room, or the space allocated for a new one, to understand its constraints — access, headroom, existing services, and how heat, water and controls need to move through it. From there we agree a layout with you, or coordinate installation against your consultant's design where one already exists, before sequencing the mechanical, electrical and controls trades involved.
Where a plant room replacement needs to happen without leaving a building without heating or hot water, we plan a phased approach and agree a shutdown window with you in advance. Once installed, the whole plant room is commissioned as one coordinated system rather than a set of separately signed-off installations, and the completed scope is confirmed on handover.
Plant rooms are often cramped, awkward to access, and serve a building that cannot simply be switched off during the works. We consider access routes for both installation and future maintenance, how the trades involved need to be sequenced, and whether heating or hot water needs to be maintained throughout the project, before finalising a plan.
Every plant room project is scoped to the specific space and building. Layout, sequencing and phasing are agreed with you before work begins rather than assumed from a standard template.

Talk to the plant room teamThis page covers the wider, multi-discipline plant room service — layout, coordination across mechanical, electrical and controls trades, and refurbishment of the whole space. Gas-specific plant room installation, focused on gas pipework and appliance connections, sits within our Commercial Gas services, and we coordinate the two where a project needs both.
Both are possible. Where your own consultant has already produced a plant room design, we coordinate installation against it. Where there is no separate design, we specify the layout within the scope agreed with you, rather than assuming open-ended design responsibility.
In many cases, yes, through a phased approach and an agreed shutdown window. This depends on the specific plant room and building, and we assess this as part of any survey rather than assuming it is always possible.
Yes. Plant room projects typically need mechanical, electrical and controls trades sequenced together, and we coordinate this as one project rather than treating each discipline separately.
Yes. Where a project already has an appointed consultant, architect or principal contractor, we coordinate our plant room scope with theirs rather than working in isolation.
A quotation sets out the agreed scope of work following our site survey, across all disciplines involved in that specific plant room. Anything outside that agreed scope is separately discussed before it is added to the project.
Tell us about the building, the existing plant room if there is one, and any existing consultant or design team. We can advise on the right approach and arrange a site survey where appropriate.
