Air Conditioner Installation Cost

In this guide, we will take a closer look at air conditioning installation cost in UK. If you want to keep the temperature in your home consistent throughout the year, you’ll want to know the average cost to install air conditioning. 

How Much Does it Cost to Install Air Conditioning?

It is important to note that air conditioning installation prices are highly dependent on the structure of the home as well as the kind of air conditioning system you want to install. The following are the primary elements that influence the air conditioner installation cost:

  • The Size of Your Home 
  • Air conditioning system type
  • Air conditioner’s build quality
  • Integrated Features available (Mobile app access, Wifi, energy rating etc)

Air Conditioner Installation Cost Per Room 

Materials for a basic single-room split air conditioning system start at roughly £300, while a multi-split air conditioning system may cost up to £1,500 per room, with a VRF system costing as much as £2,000 per room. A split air conditioning unit installed throughout the home will typically cost between £1,000 and £1,500 per room. As a result, expect to spend between £4,000 and £6,500 for a four-room apartment. 

Note: Please keep in mind that these are the average costs of air conditioning installation in the UK, and are subject to change. 


The air con installation should take somewhere around 4 and 8 hours, depending on the size of your house and the kind of air conditioner system you pick. The installation time might vary depending on whether the house is bigger or if the system is more complicated.

Additional Aircon Installation Cost 


Like other home repair projects that involve modifying a wall, no matter how meticulous your air conditioning installer is, re-plastering will be required around the installation site. In most circumstances, simply a little piece of your wall will require fixing and redesigning. A professional plasterer would generally charge in the region of £100 to perform the task. However, you can also finish it by yourself and save money.

Loft Insulation 

It’s well-known that adequate insulation may save heating and cooling expenses in the winter, but it also works in the summer. Loft insulation may assist lower AC expenses by preventing cooled air from leaking through the roof. Loft insulation costs about £2.50/m2.

Draught Proofing 

If your house is prone to draughts, your air conditioning system will have to perform harder to maintain target temperatures, therefore you may need to check if your windows and doors need to be replaced to get the most out of your new AC system and keep your operating expenses low. Purchasing new uPVC windows typically costs roughly £300.

In addition to the air conditioning unit installation cost, there are several other considerations that should be taken into account:

  • The operating expenses of your air conditioning system will have an influence on your energy bills.
  • Maintenance is required to ensure that your air conditioning unit(s) continues to operate properly. 

Estimated AC Installation Cost 

There is no such thing as a one-size-fits-all answer when it comes to HVAC. Portable devices to fully integrated systems that cover the whole house are available in a variety of sizes and configurations. Let’s look at how much to have air conditioning installed in detail.

Portable Air Conditioner Installation Cost

A portable or standalone A/C unit is the least priced option, often known as spot coolers, are an affordable and simple alternative to a permanent air conditioning system. The typical price range for a portable or freestanding air conditioner is between £150 and £350.

Split Air Conditioner Installation Cost

Split air conditioners have a wall-mounted air outlet and a compressor mounted outside the house. Adding extra outlets to a split A/C system is a simple way to enhance the system’s capacity. Maintenance is required at least once a year for these air conditioners. This wall mounted air conditioner installation cost ranges from anything between £450 to £2000. 

Window Air Conditioner Installation Cost

Unlike a split air conditioner, this system exchanges interior warm air with outside incoming cooler air, hence increasing airflow and doing it with a single unit rather than two. The typical cost of a window air conditioner ranges from £500 to £1000.

Ducted Air Conditioner Installation Cost 

A ducted air conditioning unit circulates cool or warm air throughout the home or commercial building through a network of ducts and vents, ensuring a comfortable indoor atmosphere. Condenser, compressor, and air handler are often found in the basement, loft, or garage of most homes Ducted air conditioners, on the other hand, may cost anywhere from £1000 to £1300.

Central Ducted Air Conditioner Installation Cost

Central ducted air conditioning is most often seen in workplaces and commercial buildings in the UK. The price of these systems varies greatly based on the size and features of the system. While a new central office air conditioning system may cost about £2,000, the labour needed in retrofitting a central air system to an old structure might be far more costly.
