Plant rooms & energy centres
New plant rooms and full refits for commercial buildings, from strip-out to commissioning, including live changeovers in occupied buildings.
Plant rooms & energy centres across London and the South East
CommGas installs and refits commercial plant rooms and energy centres for offices, schools, healthcare and industrial buildings across London and the South East. That covers boiler plant and flues, low-loss headers, plate heat exchangers, pump sets, pressurisation and hot water plant, together with the pipework, valves and controls interfaces that tie it all together.
Refits are where planning matters most. We programme the strip-out, any temporary heating and the changeover so the building keeps running, and we hand back a plant room that is labelled, insulated and easy to maintain.

How we work →Frequently asked questions
Can you refit a plant room while the building stays in use?
Yes. We plan the strip-out, temporary heating where it's needed and the changeover so the building can keep running throughout the works.
Do you commission the plant you install?
Yes. Our own engineers install, test and commission the plant, and we issue the commissioning records at handover.
Can you price from our drawings and specification?
Yes. Send us the drawings and specification and we'll return a clear priced scope with inclusions and exclusions.
