Buying Guide
Cooling capacity (kW / BTU)
Match the unit's cooling capacity to your room size — small bedrooms need roughly 2.5–3.5 kW (around 9,000–12,000 BTU) while larger living rooms require 4 kW or more. Choosing a unit that’s too small means it will struggle and run constantly; too large and it will cycle on and off inefficiently.
Energy efficiency and running costs
Look for the best energy rating you can afford and check the EER or kWh consumption figures to estimate running costs in GBP. Portable air conditioners are generally less efficient than fixed systems, so pay attention to eco modes, timers and thermostats to keep bills down.
Noise level and placement
Portable ACs contain the compressor inside the room so noise (measured in dB) matters — aim for models under 50–55 dB for bedrooms and quieter living spaces. Consider where you’ll place the unit and whether its fan speed, sleep mode or low-noise setting suits your needs.
Venting, installation and portability
Most units require a window or wall vent kit for the hot exhaust hose; check the included fittings and whether they suit UK sash or casement windows. Look for sturdy castors, manageable weight and an easy-to-store exhaust kit if you’ll move it between rooms or store it out of season.
Features, maintenance and warranty
Decide which extras matter: dehumidification, auto-evaporation, remote control, Wi‑Fi/smart control and washable filters all add convenience. Also check filter replacement costs, ease of draining condensate and the length of guarantee/support from UK retailers or the manufacturer.
Frequently Asked Questions
What is the best portable air conditioner in 2026?
There isn’t a single 'best' model for everyone — the right pick depends on room size, noise tolerance and budget. In 2026 look for models offering a balance of efficient cooling (kW/BTU matched to room size), A-rated energy performance, quiet operation and good UK aftercare from retailers such as Currys, AO or John Lewis.
Is a portable air conditioner worth buying in the UK?
Yes for people who need a temporary, flexible cooling solution without the expense or installation of a fixed system. They’re especially useful in rented flats or for cooling specific rooms, but expect higher running costs than a split system and the need to vent the exhaust.
Which portable air conditioner offers the best value for money?
Best value combines purchase price with efficiency, noise and reliability. Mid-range models from reputable brands that offer A-rated efficiency, a good warranty and features like auto-evaporation or dehumidify mode usually deliver the best long-term value.
De'Longhi vs Honeywell - which should I buy?
Both are established brands: De'Longhi often focuses on quieter, feature-rich machines while Honeywell tends to offer simple, reliable units at competitive prices. Base your choice on the specific model’s cooling capacity, noise level and UK service support rather than brand alone.
How do I size a portable air conditioner for my room?
Measure the floor area in square metres and multiply by the ceiling height if your room is taller than average; as a rough guide, allow about 100–140 W per m² for typical UK rooms. Consider extra load from sun-facing windows, high ceilings or many occupants and choose a slightly larger unit if the room has heavy solar gain.
Can I use a portable air conditioner in a flat with sash windows?
Yes — many portable ACs include flexible exhaust kits or window adapters that work with sash or casement windows, and there are third-party kits for awkward openings. Make sure the exhaust can be safely routed and check your tenancy agreement or building regulations before making alterations.
Are portable air conditioners expensive to run in the UK?
They can be more costly to run than fixed split systems because the compressor stays inside the cooled room, reducing efficiency. Running costs depend on the unit’s kW rating and your electricity price; using timers, eco modes and correct sizing will help keep bills under control.
Do portable air conditioners also dehumidify?
Most portable ACs remove moisture from the air as part of the cooling process and many offer a dehumidify-only mode. Check the litres-per-day dehumidification spec if this is a priority, and whether the unit has auto-drain or a convenient drainage option.
