Air conditioning quotes

Fitting air conditioning, either a single unit in one room or a multi-split system where one outdoor unit serves several indoor ones.

Is your property suitable?

Most houses. The decision is about which rooms genuinely need it, and whether one outdoor unit can serve them all, which usually works out cheaper overall than separate systems.

Typical cost range

£2,240 – £6,755

Excludes VAT.

There is a wide spread of units on the UK market. Premium brands such as Daikin and Mitsubishi cost noticeably more upfront and typically last a good deal longer, so it is a judgement about how long you plan to stay rather than about who installs it cheapest.

The other thing that changes the price is where the pipework runs. Taking it up through the loft rather than across the outside wall looks far better, but it costs more, and the extra distance can mean adding a small pump.

What to ask before hiring

Ask how many indoor units the proposed outdoor unit can actually support, and whether you could add another room later. Ask where the pipework will run and what you will see from outside. Ask about servicing: what it costs, how often, and whether the warranty depends on it.

Red flags

No conversation about where the outdoor unit goes or how much noise it makes. A quote that does not say which units are being fitted. Anyone unwilling to discuss pipework routing before the day.

Common questions

Can one outdoor unit serve several rooms?

Often yes. A multi-split system, where one outdoor unit serves several indoor ones, usually works out cheaper overall than fitting separate systems room by room.

Are premium brands worth the extra?

Brands such as Daikin and Mitsubishi cost noticeably more upfront and typically last a good deal longer. It is a judgement about how long you plan to stay rather than about who installs it cheapest.

Can the pipework be hidden?

Yes, by routing it up through the loft rather than across the outside wall. It looks far better, it costs more, and the extra distance can mean adding a small pump.

Does air conditioning need servicing?

Ask about it before you buy: what it costs, how often it is needed, and whether the warranty depends on it being done.
