What's the cheapest portable AC that actually works?
Expect to spend £200-300 for a working portable air conditioner in the UK. Anything cheaper is almost certainly an evaporative 'air cooler' — not a real air conditioner. The sweet spot for budget ACs is 7,000-9,000 BTU, which cools a standard UK bedroom (15-20m²) perfectly. Units from AuraHome, Pro Breeze, and AEG regularly appear in this range. The table below shows every in-stock portable AC under £350 — sorted cheapest first.
Cheap vs expensive — what do you give up?
Budget portable ACs (under £300) typically lack Wi-Fi/smart features, have slightly higher noise (60-65 dB vs 55-58 dB), and may not include a heat pump for winter heating. But they cool a room just as effectively as a £500 unit of the same BTU. The compressor and refrigerant cycle is the same technology. If you just need a bedroom cold for sleep during heatwaves, a £250 9,000 BTU unit is all you need.
Watch out for 'air coolers' pretending to be air conditioners
If it's £40-80 and doesn't have an exhaust hose, it's an air cooler — not an air conditioner. Air coolers blow air over water to create a cooling breeze but don't actually reduce room temperature. They work in dry climates (Arizona, not Manchester). Every unit in this table is a real compressor-based air conditioner — we've verified every listing. If it's here, it actually cools.
