Air conditioning services
Summers here are getting hotter, and most homes in Surrey and Dorset were built to keep heat in, not out. A fan moves warm air around. Air conditioning takes the heat out of the room and dries the air while it does it. We design and install home air conditioning across both counties, from a single bedroom unit to a whole-house system. Tell us which rooms overheat and we'll call you back to talk through the job.
Why more homes are fitting air conditioning
Air conditioning is still uncommon in UK homes. University of Reading researchers estimate that 4.3% of English homes, about 1.06 million, have it. The reason people are looking is the weather: compared with 1961–1990, the 2014–2023 decade had 63% more warm days, more than double the days above 28°C and more than three times the days above 30°C, and counties in the south-east now see more than 12 days a year over 28°C.
Many homes here were built to hold heat in, not shed it. Top-floor bedrooms under a roof, south-facing rooms and loft conversions can stay hot long after the sun has gone down.

What air conditioning costs to install
The price depends on the number of rooms, the length of pipe run between the indoor and outdoor units, and how the wall or ceiling is finished, so we talk the job through with you before we put a figure on it.
For context, published UK guides put a fitted single-room system at roughly £2,000–£3,500, multi-room systems from about £3,500 to £6,000 or more with around £800–£1,200 for each extra room, and ducted systems from about £5,000 to £10,000 or more. These are third-party guide prices, not ours.
which systems suit your home
We size every system to the room, not to a rule of thumb. A unit that is too big switches on and off constantly and removes humidity badly. One that is too small never catches up.
Single room
One indoor unit and one outdoor unit. The usual answer for a bedroom, home office or nursery.
Multi-room
One outdoor unit serving two to five indoor units, so bedrooms and living space are covered without a wall of outdoor boxes.
Whole house
Hidden units with ceiling vents. Suits larger refits and new builds, and costs the most. We will say if it is overkill.
What it really costs to run
Most people overestimate this. A modern 2.5kW inverter unit, such as the Mitsubishi Electric MSZ-AP25VG, draws a rated 0.60kW of electricity while delivering 2.5kW of cooling. At the current price cap of 26.32p per kWh, that is 0.60 × 26.32p, about 16p an hour at full rated output. Inverter units slow down once the room is cool, so real use is usually lower. A bedroom unit running eight hours overnight at the rated figure would cost around £1.26. Your own bill will vary with the room, the weather and how you set it.

FAQ’S
-
A fan moves air across your skin, which helps you feel cooler, but it does not lower the temperature of the room. Air conditioning takes heat out of the room, so it is the better choice for bedrooms that stay hot at night or for anyone who is vulnerable to heat.
-
A modern 2.5kW unit such as the Mitsubishi Electric MSZ-AP25VG draws a rated 0.60kW. At the current price cap of 26.32p per kWh that is about 16p an hour at full rated output, and less once the room has cooled. Your own bill will depend on the room, the weather and how you set it.
-
t depends on the type of unit, where the outdoor part goes, and whether the property is listed or in a conservation area. We check this with you before we go ahead.
-
Many modern split systems can run in reverse and heat as well as cool. We will tell you whether the unit we recommend does, when we talk through the job.
