Buying Guide
Room size and cooling capacity (BTU)
Match the unit's cooling capacity to the room size — for a single person’s bedroom or small lounge you typically need around 6,000–10,000 BTU. Too small and the room won't cool; too large and the unit will cycle inefficiently, raising running costs.
Noise level
Portable air conditioners can be noisier than fixed systems, so check the decibel (dB) rating — look for models marketed as 'silent' or 'low-noise' if you’re sensitive to sound. Consider where you sleep or work and read real-world reviews, not just manufacturer figures.
Installation and portability
Most portable ACs need a simple exhaust hose fitted to a window kit; ensure the kit fits your window type and measures provided by the manufacturer match your window gap. Look for castors, manageable weight and a compact design if you plan to move the unit between rooms or store it in winter.
Energy efficiency and running costs
Check the energy efficiency rating (EER) or kW per hour consumption to estimate running costs — cheaper units can cost notably more to run during a heatwave. Also consider modes such as eco, sleep, timers and programmable thermostats to reduce usage.
Features and maintenance
Decide which extras matter: a dehumidifier mode, fan-only, remote control, app connectivity or a washable filter. Factor in ease of draining condensate, filter cleaning and availability of spare parts — these affect long-term convenience and hygiene.
Frequently Asked Questions
What is the best portable air conditioner in 2026?
There’s no single 'best' model for everyone — the top pick depends on room size, noise tolerance and budget. For singles in small rooms, look for compact 6,000–10,000 BTU units from reputable brands (De'Longhi, Honeywell, Klarstein) with good real-world noise reviews and efficient EER ratings; check Currys, AO or John Lewis listings and recent buyer reviews for 2026 updates.
Is a portable air conditioner worth buying in the UK?
Yes, for renters or people who need spot cooling without installing a fixed system, portable ACs are worthwhile — they’re easy to set up and move. Bear in mind higher running costs than heat pumps or mains AC and the requirement to vent through a window, which may not suit every property.
Which portable air conditioner offers the best value for money?
Best value balances purchase price, efficiency and features: mid-range models around £250–£450 often give the best compromise for singles, offering reasonable cooling, timers and low-noise modes. Compare EER/kW, warranty and typical running costs per hour to decide value rather than just the sticker price.
De'Longhi vs Honeywell - which should I buy?
De'Longhi models tend to focus on quieter operation and sleeker design, while Honeywell often offers robust cooling performance at competitive prices. Choose De'Longhi if noise and build finish matter; pick Honeywell if you want raw cooling power and slightly lower price points — check specific model reviews for noise and efficiency.
How much does it cost to run a portable air conditioner in the UK?
Running costs depend on the unit’s power (kW) and local electricity prices; a small unit using about 1–1.5kW can cost roughly £0.30–£0.60 per hour at typical UK domestic rates (prices vary). Use the kW figure on the spec sheet and multiply by your per-kWh rate for a precise estimate.
Can I use a portable AC in a flat or rental property?
Yes — portable ACs are a good option for flats and rentals because they require no permanent installation, only a window vent kit for the exhaust hose. Check building or landlord rules about window alterations and consider a secondary seal or sash lock if security is a concern.
Do portable air conditioners dehumidify effectively?
Many portable ACs include a dehumidify mode and will remove moisture as part of the cooling cycle, which helps rooms feel less muggy. For very damp conditions, a dedicated dehumidifier is more efficient, but for occasional summer humidity a portable AC is usually adequate.
Are smart or app-connected portable ACs worth it?
Smart functions (Wi‑Fi, app control, voice assistants) add convenience — remote scheduling and geofencing can save energy — but they usually add to the price. If you mainly need simple cooling in a single room, a good basic unit with a timer and remote often suffices.
