How Much Does Air Conditioning Cost? (UK Guide)

All our prices are from-prices, include VAT, and cover the unit supplied and fitted with free delivery. A 2.5kW unit starts at £1,450, a 3.5kW at £1,499, a 5kW at £1,750 and a 7kW at £1,950.

The size you need depends on the room — a small bedroom takes a 2.5kW, a living room usually a 3.5kW, and a large or open-plan space a 5kW or 7kW. We confirm the right size and the final price after a quick look at your space.

The price includes the unit itself, free delivery, and the full installation — the indoor unit mounted high on the wall, the outdoor unit positioned to suit your property, and neat pipework and trunking. We leave the room as we found it.

It also includes a walkthrough on how to use the system before we leave, so you know how to cool, heat and set the modes you want.

The main add-on is a condensate pump, at £130. Air conditioning produces a small amount of water when it runs, and if the unit can't drain it away by gravity, a pump moves it to a suitable drain. We'll tell you if your install needs one before we start.

Larger rooms or businesses may need a bigger unit, which costs more. But we'll always recommend the right size for the space — not a bigger unit than you need.

"From" means that's the starting price for a straightforward install. Most home installs come in at the from-price, because a wall-mounted split unit in a typical room is a clean, predictable job.

We confirm the final price in writing before any work starts, including any extras like a condensate pump.

The simplest way to get your price is to tell us the room and roughly how big it is. We'll recommend the right size and give you a clear price. You can use the calculator on our quote page, call us, or send your details through the contact form.

There's no charge for a quote and no obligation. We come out, look at the space, and leave you with a price to think about.
