Comfort and productivity are closely linked
Research on workplace comfort consistently finds that productivity drops once room temperature climbs much above 24–25°C, and concentration suffers well before anyone would describe the room as uncomfortably hot. This makes office air conditioning less of a luxury than it might seem, whether it’s a single home office or a full commercial floor.
Home offices
A converted spare room or garden office used for work benefits from the same considerations as a bedroom installation — reasonably quiet operation, since video calls and quiet concentration don’t suit a noisy unit, and a system sized correctly for the room rather than oversized on the assumption that bigger is always better, which can lead to a room that cools too quickly and then cycles on and off inefficiently.
Commercial office spaces
Larger offices typically use ceiling cassette or ducted systems that integrate with a suspended ceiling, keeping the space visually uncluttered and allowing air to distribute evenly across an open-plan floor. Zoning matters considerably here — a meeting room that’s empty most of the day shouldn’t be cooled to the same degree as a busy open-plan area, and a well-designed VRF system allows each zone to be controlled independently.
Typical costs
A single home office installation is broadly comparable to a bedroom installation, typically £1,500–£2,500 fully fitted. Commercial office installations are usually quoted per zone or per square metre, reflecting the larger scale and more complex ductwork typically involved — see our commercial air conditioning page for detail on that pricing.
Minimising disruption
For occupied offices, installers commonly schedule work outside business hours or across a weekend, and can phase installation across zones so parts of the office remain usable throughout.
