Best Portable Air Conditioners in the UK 2026
UK summers are getting hotter, and a portable air conditioner offers flexible cooling without permanent installation. Unlike window units, portable ACs work in any room and are ideal for renters. This guide reviews top-rated models available on Amazon UK, from budget-friendly Dimplex units (around £250) to premium De'Longhi and Meaco systems (£400–£600). we've researched cooling capacity (measured in BTU), noise levels, energy efficiency (EER ratings), and venting requirements. All models carry CE marking and comply with UK energy labels. Whether you're cooling a bedroom, office, or living room, you'll find options for rooms up to 40m². Our picks prioritise reliability, warranty support, and UK availability.
What to Look For
- 1Check the BTU (cooling capacity): 8,000–10,000 BTU for small rooms (under 15m²), 12,000–16,000 for medium spaces (15–25m²).
- 2Look for EER (Energy Efficiency Ratio) above 2.8; UK energy labels show A–G ratings—A is most efficient and cuts running costs.
- 3Ensure single-hose or dual-hose venting works with your windows; most require a window sash seal kit (included or sold separately).
- 4Noise levels: quieter units (under 68dB) suit bedrooms; louder models (70dB+) are acceptable in living areas.
- 5Check warranty: UK Consumer Rights Act 2015 mandates 2 years; reputable brands offer 3–5 year options.

Editor's Note
All models carry CE marking and UK energy labels (typically D or E rating). Choose dual-hose units (Meaco, Bosch) if energy bills concern you; single-hose (De'Longhi, Dimplex) are cheaper upfront but less efficient. Room temperature drops 1–2°C per hour in sealed rooms. Under UK Consumer Rights Act 2015, all carry minimum 2-year coverage; premium brands offer 3–5 years. British Standard BS 5422 applies to refrigerant handling—buy only from certified installers if DIY venting seems risky. Dehumidifying built-in on most models helps reduce condensation in damp UK basements.
