Wall-split installations run roughly £205-500 per kW installed. A 5kW unit fully installed is £1,240-3,200; a 12kW multi-head system is £3,440-9,000. Ducted systems run £480-1,200 per kW because of the ducting work.

Heat-load rule of thumb: 0.15kW per square metre in moderate climates, 0.20kW in hot climates. A 25sqm bedroom needs 4-5kW; a 50sqm open-plan needs 7-9kW. Over-sized units short-cycle and waste energy; under-sized never cool the room. Insist on a heat-load calc for any install over £2,060.

For installs over £1,380, get 2-3 quotes. Compare brand, capacity, warranty, refrigerant type, and install detail. The cheapest quote often uses budget brands with 3-year warranties vs branded units with 5-7 year warranties for 10-20% more.

Wall splits are individual units, cheaper, easier to install, each room independent. Ducted is one outdoor unit with hidden roof-space ducting to all rooms, more expensive but cleaner aesthetic and centralised control. Wall splits cost half what ducted does for the same total kW.

A standard 5kW wall-split install is 4-6 hours for a 2-person team. Multi-head and ducted systems take 2-3 days. Larger commercial or ceiling-cassette installs take 4-5 days.
