Air conditioning installation
From a single bedroom unit to a whole-house multi-split system, see what installation is likely to cost before you speak to anyone — then compare up to three local installers.
Survey first
A good installer checks room sizes, heat gain, pipe routes and where the outdoor unit can go before giving a final price.
F-Gas certified
Split systems contain refrigerant, so installation must be done by an F-Gas certified engineer. We display exactly what we have checked for each installer.
Heating too
Most modern split systems are air-to-air heat pumps and can heat efficiently in winter as well as cool in summer.

Frequently asked questions
How long does installation take?
A single-room split system is usually fitted in one day. Multi-room systems typically take 2–3 days depending on pipe runs.
Do I need planning permission?
Most domestic installations fall under permitted development, but listed buildings, conservation areas and flats often need extra checks. Your installer should advise.
