What moves the price
- Number of rooms — a single-room split costs far less than a multi-split serving three or four rooms
- System type — wall-mounted split units are cheaper than ducted or concealed air conditioning
- Capacity — larger rooms and conservatories need more powerful indoor units
- Pipe runs — long runs between indoor and outdoor units add labour and materials
- Electrical work — the air conditioning may need a dedicated circuit, which brings in an electrician
- Brand and efficiency — premium, quieter inverter units cost more upfront
Plumbing and heating prices in the UK are up 6% over five years (ONS Consumer Price Inflation, Services for maintenance and repair, to 2026 August). Five years ago a typical air conditioning installation would have cost about £2840 — an estimate from today's guide price and that index, not a recorded price. Source: ONS MM23 D7DO →

How to pay less
- Cool the rooms that need it most rather than air conditioning the whole house
- Choose a multi-split if you need several rooms, which shares one outdoor unit
- Book air conditioning installation in autumn or winter, when installers are less busy
Before you book
- Only an F-gas certified engineer may install and charge an air conditioning system
- Check whether the outdoor unit needs planning permission, especially on listed buildings or in conservation areas
- Ask about the noise level of the outdoor unit if it will sit near a neighbour's window
- New circuits for the air conditioning should be certified under Part P
Air Conditioning Installation cost: questions people ask
£1,500–£7,000 per install, about £3,000 typical. A single-room split system costs least; a multi-split for several rooms costs the most.
About a day for a single room and two to three days for a multi-split system.
Often not for a single outdoor unit, but rules on position, size and noise apply, and listed buildings or conservation areas may need consent.
Many modern units are air-to-air heat pumps that heat efficiently in winter as well as cooling in summer.
New electrical circuits, making good walls and decoration, and annual servicing are often extra.
