Multi-split air conditioning cost guide
How much a multi-split air conditioning system costs for two or three rooms, and when a multi-split makes sense. Fixed prices from £3,295.
What is a multi-split?
A multi-split connects two or more indoor units to one outdoor unit. It means fewer boxes on the outside of your home and fewer holes in the wall.
Our fixed multi-split prices
- Two bedrooms (Mitsubishi Heavy Industries 2-way multi-split) — from £3,295
- One bedroom + living room (nominally 2.0kW + 3.5kW) — from £3,595
- Two bedrooms + living room (2-way multi-split plus a standalone 3.5kW system) — from £4,995
Multi-split or separate singles?
Multi-splits save outside space. Separate single systems mean one failure doesn't affect other rooms and can suit rooms far apart. We'll recommend what fits your home after seeing your photos.
