How much does home air conditioning cost?
By Airva Editorial · Reviewed by Airva Technical Review · Updated 13 July 2026
Most UK homes spend between £1,500 and £3,000 for a single-room split system, and £4,000 to £8,000 or more for a multi-room or whole-home installation. The final figure depends on your property, not a fixed price list.
What drives the price
- Number of indoor units — each room you cool adds equipment and labour.
- Number of outdoor units — a multi-split shares one; separate systems need more.
- System type — single split, multi-split, or concealed ducted (the most involved).
- Installation complexity — pipe runs, access, working at height, and electrical work.
- Concealment — hiding pipework inside walls costs more than surface trunking.
Getting a realistic figure
A rules-based cost estimator gives you an indicative low-to-high range from these variables in a couple of minutes. It is a guide, not a quotation — the firm price comes from an installer survey.
