The cost of air conditioning depends on the type of system, the number of rooms, how hard the install is and the brand. The figures below are typical UK guide prices for supply and installation. Your own price depends on a survey.
Typical installation costs
| System | Typical installed cost |
|---|---|
| Single wall-mounted unit, one room | £1,500 to £2,500 |
| Multi-split, two to three rooms | £3,500 to £7,000 |
| Ceiling cassette, per unit | £2,500 to £5,000 |
| Ducted system | £5,000 and up |
| VRF for a larger building | Priced per project, often tens of thousands |
Prices rise with long pipe runs, difficult access, work at height, electrical upgrades and out-of-hours working.
Running costs
A typical single-room unit uses well under a kilowatt of electricity while running, so it usually costs pence per hour to run, depending on your tariff, the size of the room and how hard the system is working. Systems with good efficiency ratings cost less to run.
Servicing
Most systems need servicing once a year. Paid separately, an annual service typically costs from around £100 to £200 per unit, more for larger commercial systems.
Buying outright or paying monthly
Buying outright means paying the full installed price upfront, then paying for servicing and repairs as they come up. On a SteadyTemp plan there is no upfront cost: one fixed monthly payment covers the system, installation, an annual service and parts and labour cover. Single-room plans start from £29 a month.
