Choosing The Best Type Of Air Conditioning System UK

When it comes to choosing the best type of air conditioning system for your property, it is important to consider all of your options. The best system for your property will primarily depend on the size of the space that you are looking to cool and your visual preferences. Another important factor to consider is whether you need planning permission to install air conditioning in your property. This will affect what type of system you are allowed to install.

Split System

Split systems are one of the most common choices for homeowners in the UK. The system consists of an indoor fan unit and an external condenser. The two are connected with piping and electric wiring in order for the refrigerant to travel between the units. Available in different sizes, these systems can accommodate anything from small bedroom offices and meeting rooms to large open-plan living areas and shop floors. additionally, most modern air conditioners are energy-efficient, keeping running costs at a minimum.


  • Quick installation
  • Cost-effective
  • Available in different sizes
  • Versatile
  • Energy-efficient


  • The external condenser can be noisy
  • May require planning permission depending on the property type
  • Not suitable for all property types

Multi-Split System

Multi-split systems consist of multiple indoor units connected to a single external condenser. This type of system is ideal if you’re looking to cool multiple rooms such as bedrooms and living spaces or large open-plan areas such as offices or shops. The units are connected through pipes and electrical cables. In addition, this type of system allows you to control the temperature of each unit independently.


  • Versatile
  • Independent temperature control
  • Easy installation
  • Energy-efficient


  • External units may be noisy
  • May need planning permission for an external condenser
  • Not suitable for all property types

Ducted System

Ducted systems are ideal if you are looking for a more discrete solution. This type of unit is usually installed in a false or suspended ceiling. The only visible element is the vent grilles in the walls or ceiling. The temperature of the entire system is controlled with a wall-mounted control panel.


  • Discrete and visually appealing
  • Space saving


  • Slightly more costly than split units
  • Additional building work may be required with installation
  • Not suitable for all properties

Portable Systems

Portable air conditioning systems are ideal if you are on a tight budget. They allow you to cool single rooms, with the flexibility of being able to move the unit between rooms as required. This type of unit usually requires a ventilation pipe to release hot air to the outside. These are usually connected to a window.


  • Budget-friendly
  • No installation required
  • Low maintenance costs


  • Requires open window for ventilation
  • Lower cooling capacity than traditional systems
  • Takes up floor space

Water Cooled System

Water-cooled air conditioning systems are ideal for restricted properties such as apartments and Grade II listed buildings. This type of system consists of an internal fan unit and an internal water-cooled condenser. Unlike traditional systems, the condenser is installed inside the property. It is plumbed into your mains water supply and uses water in a controlled manner to cool the air.


  • No external condenser
  • Suitable for apartments & Grade II listed buildings
  • Energy-efficient
  • Low noise & Wi-Fi control


  • More expensive to install than traditional air conditioning
