Buying Guide: Portable Air Conditioners for UK Homes
UK summers are becoming hotter and more unpredictable. Portable air conditioners offer a practical solution for renters and homeowners who can't install fixed air conditioning. Here's what to consider before buying.
BTU: How much cooling power do you need?
BTU (British Thermal Units) measures cooling capacity. As a starting point, multiply your room area in m² by 337. A 15m² bedroom needs approximately 9,000 BTU. Use our BTU Calculator for a more precise recommendation.
Single-hose vs dual-hose
Single-hose models are more affordable and compact. Dual-hose models are more efficient because they draw intake air from outside rather than from the room. For most UK rooms under 25m², a single-hose model is adequate.
Energy class and running costs
At the current UK electricity price of approximately £0.24/kWh, a 900W portable air conditioner running 8 hours per day costs around £1.73. An A+ rated model at 700W costs around £1.34 per day — a meaningful saving over a long summer.
Noise level for bedroom use
For bedroom use, look for models rated at 50 dB or below. The quietest models in our comparison reach 42–44 dB — comparable to a quiet library.
