Central plant works — chillers, AHUs and chilled-water systems

Hospitals and data centres can't switch off to let you work.

What we do

Plant replacement in live buildings

Our chiller and CHW teams replace and extend central plant in live environments — chiller additions and replacements, AHU replacements, chilled-water piping, pipe freezing and hot tapping — sequenced so the building keeps running.

Twenty-five installers and technicians across the two teams, with electrical works carried out under our own ME05 registration rather than passed to a third party.
