FAQ
Short answers before you open Amazon.
Do I need a compressor air conditioner or will an air cooler work?
For UK heatwaves you want a true compressor portable air conditioner with an exhaust hose. Evaporative air coolers mainly move humid air and struggle in muggy British summers.
How many BTU do I need for a UK room?
About 9,000 BTU under 20 m², 10,000–12,000 BTU for most living rooms, and 12,000–13,000 BTU for open-plan spaces. Always check the manufacturer room-size guidance.
Can renters use a portable air conditioner?
Yes. Portable units vent through a window kit rather than fixed outdoor pipework, which makes them practical for flats and rented homes when the kit seals well.
Are the Amazon links affiliate links?
Yes. We may earn a commission from qualifying purchases via Amazon UK using affiliate tag view0b0c-22. Prices and stock change on Amazon.

How to choose an air conditioner in the UK (2026)
Most UK homes cannot easily install a fixed split-system air conditioner, so portable units with an exhaust hose remain the practical choice for flats and rented properties. Look for a true compressor air conditioner (not an evaporative “air cooler”), match BTU to room size, and plan a window kit that seals well — poorly sealed kits leak hot air back into the room and waste electricity.
As a rule of thumb for British homes: around 9,000 BTU suits smaller bedrooms under 20 m², 10,000–12,000 BTU covers most living rooms, and 12,000–13,000 BTU helps open-plan spaces. Check noise figures if you sleep near the unit; Class A energy ratings and self-evaporating condensate systems reduce running cost and emptying chores during a sustained heatwave. Wi-Fi models let you pre-cool before you get home, which is useful on commuting days.
