Best Portable Air Conditioners UK 2026
Ranked by performance, noise, and value — with live stock and prices from Amazon and eBay UK.
1. What a good portable AC costs in 2026
| BTU | Typical price range | Room size |
|---|---|---|
| 7,000 BTU | £200–280 | Small bedroom (9–12 m²) |
| 9,000 BTU | £280–380 | Bedroom / small living room (14–18 m²) |
| 12,000 BTU | £350–450 | Living room / open plan (18–25 m²) |
| 14,000 BTU | £420–600 | Large rooms (25–35 m²) |
Prices spike 10–25% during a live heatwave. If you can, buy in March–May when stock is plentiful and prices are lower. The figures above are normal-season prices from Amazon UK and eBay UK.
2. Who shouldn’t buy a portable AC
If you own your home and plan to use AC every summer for 5+ years, a fixed split system (installed by an F-Gas engineer) costs more upfront (£1,500–3,000) but is 3–5× more efficient and far quieter. A portable AC is the right choice for renters, or anyone who needs cooling for occasional heatwave events without structural changes.

4. Who each BTU size is for
Small bedroom (9–12 m²): 7,000–9,000 BTU is sufficient. The smallest units are also the quietest and cheapest to run.
Master bedroom or living room (up to 20 m²): 9,000–12,000 BTU. A south-facing or top-floor room in summer should go to 12,000 BTU even if it measures smaller.
Open-plan or large rooms (20–35 m²): 12,000–14,000 BTU. Anything smaller will run at 100% duty cycle and never quite reach the set temperature.
Conservatory: 14,000+ BTU minimum — conservatories gain heat faster than any other room and the effective ceiling for a portable AC is around 35 m².
