Our single-room systems start from £1,495 supplied and fitted. Across Surrey, most quotes for one room fall between about £1,600 and £2,500, depending mainly on the brand and how easy the installation is.
Prices by range
These are our starting prices for a typical single-room wall-mounted system, fully installed:
| Range | Single room, fitted |
|---|---|
| Essential (Midea Xtreme Save Lite) | from £1,495 |
| Comfort (Toshiba Seiya) | from £1,745 |
| Premium (Daikin Sensira or Mitsubishi Electric MSZ-HR) | from £2,195 |
| Two-room multi-split, Essential (Midea) | from £2,795 |
| Three or more rooms, cassette or ducted | priced after survey |
All three ranges cool and heat, and all are fitted to the same standard. The more expensive ranges run more quietly, use slightly less electricity and add features such as app control. We are not VAT registered, so there is no VAT to add to these prices.
What changes the price
- Number of rooms. Each extra room needs an indoor unit. A multi-split system lets one outdoor unit serve up to five rooms, which is usually cheaper and tidier than several separate systems.
- Size of the room. Larger rooms, south-facing rooms and rooms with lots of glass need a more powerful unit. We work this out properly at the survey rather than guessing.
- Type of indoor unit. Wall-mounted units are the most affordable. Ceiling cassettes and concealed ducted units cost more to supply and fit.
- Pipe run and outdoor unit position. The further apart the indoor and outdoor units are, the more pipework and labour is needed. Outdoor units fitted high on a wall, or where access is difficult, take longer to install.
- Making good. Hiding pipework inside walls or ceilings costs more than running it in neat trunking.
What does air conditioning cost to run?
Less than most people expect. A modern inverter unit slows down once the room reaches temperature, so a typical bedroom unit uses a few hundred watts for most of the time it runs. At current electricity prices that is roughly 20p an hour, and less in mild weather. Used for heating, it is usually far cheaper to run than plug-in electric heaters. See our guide to heating with air conditioning.
Servicing costs
An annual service starts from £85 for the first indoor unit and £40 for each extra unit on the same visit. Regular servicing keeps the system efficient and is usually a condition of the manufacturer warranty. Read how often air conditioning should be serviced.
