Air conditioning is becoming more popular across the UK, especially as summers seem to be getting warmer every year. Whether it’s for a bedroom, home office or living space, more homeowners are choosing to install air conditioning to stay comfortable all year round.

One of the first questions people ask is:

“How much does air conditioning installation cost?”

The honest answer is that it depends on the type of system and the size of the space, but this guide will give you a good idea of what to expect.

Average Cost of Air Conditioning Installation in the UK

or most homes in the UK, the most common type of system is a wall-mounted split air conditioner. These are quiet, energy efficient and perfect for cooling individual rooms.

• Single room system: around £1,200 – £3,500

How Much Does Bedroom Air Conditioning Cost?

Bedrooms are one of the most popular places to install air conditioning. A cool bedroom can make a huge difference to your sleep, especially during those warm summer nights.

Installing air conditioning in a typical bedroom usually costs between £1,200 and £2,500, depending on things like:

• the size of the room

• where the outdoor unit can be placed

• how far the pipework needs to run

• any electrical work required

The good news is that modern systems are very efficient and can also provide heating in winter, so they’re useful all year round.

What If You Want Air Conditioning in Multiple Rooms?

Typical costs can look something like this:

• 2–3 rooms: £2,300 – £5,500

• 4–5 rooms: £5,500 – £8,000+
