Checkatrade's May 2026 national guide puts a single wall-mounted system at about £1,900 to £2,240 for the unit and labour, plus £400 to £700 for electrical work. See what air conditioning costs.

Checkatrade gives about 20p to 60p an hour, depending on the system, its age and the insulation. At the October to December 2026 price cap, electricity costs 26.32p per kWh. See the sums.

Ask for the company certificate number and the body that issued it, such as Refcom, F-Gas Register or Bureau Veritas, then check it with that body. See F-gas rules.

Most modern split systems can. They work as air-to-air heat pumps in winter. See can air conditioning heat your home.

Much cheaper to run. With a seasonal efficiency of 4, each unit of heat costs about a quarter of what a direct electric heater costs.

Not in almost all cases. Keep your boiler, immersion or cylinder for that.

Roughly 2 to 2.5kW for 15 to 25 square metres, before you allow for sun, glass and ceiling height. See what size you need.

Usually. In England a new circuit is notifiable under Part P of the Building Regulations, so it must be certified.

Yes. That is a multi-split system, and it suits terraced houses where there is space for only one outdoor unit.

Often, with the freeholder's written consent. The planning rules allow one outdoor unit of up to 0.6 cubic metres on a block of flats, and there are other conditions.

Portable for a short-term or rented room, fixed if you want to stay cool and quiet for years. See portable or fixed.

Often not, for a reversible unit on a house that meets the permitted development conditions. See our planning guide.

The unit cannot go on a wall or roof facing a road, or sit nearer the road than the building. Maidstone has 41 conservation areas.

To use permitted development rights, the limit is 37 dB(A) one metre outside the nearest neighbouring door or window to a habitable room.

No. The law asks for a reasonable temperature indoors, and employers must assess the risks from heat. See office air conditioning.

An energy inspection required at least every five years where a building's air conditioning adds up to more than 12kW.

Follow the maker's handbook. Most home systems should have a yearly service, and busy or dusty sites may need more. See servicing.

Usually a blocked drain. Switch the unit off and put something under the drip. See repairs.

No. It is a sealed system, so if the refrigerant is low there is a leak to find and fix.

Yes. Tell us the make and model when you ring.
