Office air conditioning is a design problem, not a hardware problem. Get the zoning, acoustic and occupancy load wrong and you'll have hot desks next to freezing ones. We match you with commercial installers who handle full design, install and maintenance.
System types for offices
Small offices (under 100m²): multi-split ceiling cassettes. Medium offices (100–500m²): VRF with cassettes per zone. Large offices: VRF with ducted concealed units and BMS integration.
Typical UK install cost
Small office (4 cassettes): £8,000–£14,000. Mid-size office (8–12 cassettes + VRF): £25,000–£55,000. Large floorplate (50+ cassettes): £80,000+.
What to ask the installer
Heat load calculation per zone, acoustic targets (NR30 or better in open plan), commissioning paperwork, F-Gas register entry and ongoing service plan.
