| Multi-split, two rooms | £3,000 to £5,500 |
| Multi-split, three rooms | £4,500 to £7,500 |
| Four or more rooms | £6,500 to £10,000+ |
| Annual service, per system | £80 to £150 |
These are not quotes
Your price depends on the property. The only way to get an accurate figure is a survey, and it’s worth comparing two or three.
What changes the price
- The capacity and brand of the equipment. Larger rooms, conservatories and loft rooms need more capacity.
- Long or complicated pipe runs, especially between floors or through solid walls.
- Electrical work, such as a new dedicated circuit or a consumer unit upgrade.
- Access for the outdoor unit. Upper-floor or roof positions can need scaffolding or a tower.
- Hiding pipework in walls or ceilings instead of running it in surface trunking.
- A condensate pump where the water can’t drain away naturally.
- Coastal locations, where installers may recommend corrosion-protected units or extra fixings.
Comparing quotes
“From” prices online are rarely comparable. Ask each installer to itemise the quote so you can see like for like:
- The exact indoor and outdoor models and their capacity.
- Labour, pipework and any making good.
- Electrical work and certification.
- Refrigerant handling by an F-Gas certified engineer.
- The manufacturer’s warranty length and any servicing it requires.
Our questions to ask an installer cover the rest, and our running costs guide explains what the system will cost to use once it’s in.

- An annual service typically costs £80 to £150 per system. Many manufacturers require regular servicing to keep the warranty valid.
