As summers in the UK get warmer and more unpredictable, more homeowners are turning to air conditioning—not just for cooling, but also for efficient heating. But with so many systems on the market, how do you choose the best AC units for your home?
This guide covers the best AC units for UK households in 2025, including top brands, types of systems, and key features to look out for.
What Type of Air Conditioning Is Best for UK Homes?
The most common systems for domestic properties in the UK include:
1. Wall-Mounted Split Systems
Ideal for: Bedrooms, Living rooms, Offices
Pros: Quiet, energy-efficient, reliable
Cost: From £1,500 installed
These are the most popular choice for UK homes. One indoor unit is mounted high on the wall and connected to an outdoor condenser. They’re great for individual rooms and offer both cooling and heating via heat pump technology.
2. Multi-Split Systems
Ideal for: Larger homes with multiple rooms
Pros: Cool/heat multiple rooms from one outdoor unit
Cost: From £2,500–£5,000+
You can connect up to 4–5 indoor units to a single outdoor unit. Perfect for whole-house control.
3. Ducted Systems (Central AC)
Ideal for: New builds or full renovations
Pros: Discreet, invisible installation
Cost: £6,000–£12,000+
These are hidden in ceilings or loft spaces, distributing air via ductwork. Best suited to homes undergoing refurbishment.
