Where a project spans plant rooms, mechanical installation, and coordination across gas, heating, plumbing and HVAC disciplines, ComGas provides mechanical services for offices, schools and commercial buildings across Surrey and surrounding counties — surveyed, specified and coordinated against an agreed scope.
Some commercial projects are naturally single-discipline — a boiler replacement, a pump installation, a ventilation upgrade. Others need several disciplines coordinated at once: a plant room refurbishment touching gas pipework, heating circuits, pumps and controls; a full mechanical installation for a new or refurbished building; or a wider commercial refurbishment where mechanical services need to be re-planned around a changed layout. Mechanical Services is the category we use for that cross-discipline work.
ComGas provides mechanical services for offices, schools, retail developments and other commercial buildings across Surrey and surrounding counties, coordinating our own gas, heating and plumbing teams and, where your project already has an appointed consultant or design team, coordinating installation against their design rather than duplicating it. Where no separate design exists, we specify the mechanical installation within the scope agreed with you.
This hub currently has a dedicated page for Plant Rooms — the multi-discipline plant room design, installation and refurbishment service. Full mechanical installations, mechanical design input, mechanical upgrades and commercial refurbishments are all part of the wider mechanical services scope we cover; get in touch and we can confirm how your specific project is scoped even where it does not yet have its own dedicated page here.

Multi-discipline plant room design input, installation and refurbishment, coordinating mechanical, electrical and controls trades.
Planned. Professional. Practical.
A multi-discipline mechanical project starts the same way as a single-discipline one — with a survey of the existing installation and a clear scope agreed with you. What changes is the coordination: gas, heating, plumbing, electrical and controls trades all need to be sequenced correctly, particularly in a plant room where several systems share the same space and, often, the same shutdown window.
Where your project already has an appointed consultant, architect or M&E designer, we coordinate installation against their design and specification. Where no separate design team is involved, we specify the mechanical installation within the scope you agree with us, rather than assuming open-ended design responsibility across the whole project. Either way, the same team stays involved from survey through to handover, so nothing is lost between disciplines.
Existing ComGas customers can use the Customer Portal to access relevant job and service information relating to mechanical services 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 mechanical services work.

Common questions about scope, coordination and what to expect from a mechanical services project.
Talk to the mechanical services teamGenerally, any project where more than one discipline — gas, heating, plumbing, electrical or controls — needs coordinating together, such as a plant room refurbishment or a full mechanical installation for a refurbished building.
Both are possible. Where your own consultant or design team has already produced a specification, we coordinate installation against it. Where there is no separate design, we specify the mechanical installation within the scope agreed with you.
Yes. This hub currently has a dedicated page for Plant Rooms. Full mechanical installations, mechanical design input, mechanical upgrades and commercial refurbishments are all part of our wider mechanical services scope — get in touch and we can confirm how your project is scoped.
Yes. Where a project already has an appointed consultant, architect or principal contractor, we coordinate our mechanical scope with theirs rather than working in isolation.
We plan the shutdown and sequencing across all trades involved as one programme, agreed with you in advance, so gas, heating, plumbing, electrical and controls work is coordinated rather than causing repeated separate periods of disruption.
A quotation sets out the agreed scope of work following our site survey across all disciplines involved. Anything outside that agreed scope is separately discussed before it is added to the project.
Tell us about the building, the disciplines involved, and any existing consultant or design team. We can advise on the right approach and arrange a site survey where appropriate.
