This weekend marks the second amber heat‑health alert in June for London, the East Midlands, South East, South West and East of England. Temperatures are set to exceed 30 °C from Friday through Tuesday, with a rare 34 °C peak expected in the southeast by Monday—another dangerous UK heatwave especially for older adults and anyone with heart or lung issues.
Public health bodies are urging people to:
- Stay hydrated
- Avoid mid‑day sun
- Check on the vulnerable
- Recognize signs of heat exhaustion and stroke
This isn’t just “a bit warm”—it’s a serious situation. Portable air conditioning units are fast becoming lifesavers in homes that weren’t built for this kind of heat. Let’s dive into the top-performing models on Amazon UK that are truly selling like hotcakes.
Why Portable AC Is a Must for This UK Heatwave
- No installation fuss: No drilling, patching, or landlord hassle—perfect for renters.
- True cooling + dehumidifying: Evaporative coolers don’t cut it when humidity hits 60–70 %.
- Portable savings: Use in whichever room you’re in, then store away in winter.
- Energy-wise: Class A units run smart and won’t drain your wallet.
- Peace & quiet: Night-friendly models run under 60 dB—much gentler than a noisy fan.
Crowd-Favourite Portable AC Units to Fight the UK Heatwave
1. KGOGO Portable Air Conditioner – Top Pick for Bedrooms & Home Offices
- Specs: 9 000 BTU, 269 ft² (~25 m²)
- Modes: Cooling • Fan • Dehumidify • Sleep
- Noise: < 60 dB in Sleep
- Extras: R290 refrigerant, 24‑h timer, child‑lock, remote & panel
- Mobility: Handles + 360° casters
Why it’s flying off shelves
User reviews call it a “calm breeze in a hot boxing day afternoon”—highlighting how the Sleep Mode dims the display and keeps hum to a whisper. People in UK flats say it “cooled our south-facing bedroom in minutes with near-silent operation.” The sliding-window kit is a hit in cramped London flats, fitting perfectly without hacksaws.
Heads-up
At 28 kg it’s hefty, so you’ll want two people to move it upstairs—but buyers say it’s worth it.
2. LEENON Portable Air Conditioner – Best for Larger Rooms & Basements
Air Conditioning Unit 9000 BTU, LEENON Portable Air Conditioners, 4-in-1 Cooling Dehumidifier Fan & Sleep Mode, 2-Speeds Air Conditioners for Home, Remote Control, 24H Timer, Window Kit Included
- Specs: 9 000 BTU, 370 ft² (~34 m²)
- Modes: Cooling • Fan • Continuous Dehumidify • Sleep
- Noise: ~65 dB (high); quieter on Eco
- Extras: R290, LED display (17–30 °C), child‑lock, 24‑h timer
- Mobility: Roller casters, side handles
Why shoppers can’t get enough
Reviews rave it’s “like air-conditioning on steroids, for twice the space.” The continuous drain option is great in humid regions; they mention “just hooked it to a pipe and never emptied the tank all weekend.” It works hard, but Eco mode keeps noise reasonable for evening use.
Heads-up
High-fan mode is noticeable, so for late-night use you’ll likely dip into Eco.
3. Pro Breeze 4‑in‑1 Portable Air Conditioner – Most Budget-Friendly UK Brand
Pro Breeze 4-in-1 Portable Air Conditioner 7000 BTU with Remote Control, 24 Hour Timer & Dual Window Venting Kit Included. Powerful Air Conditioning Unit with Class A Energy Efficiency Rating

- Noise: ~62 dB
- Energy: Class A, R290

Why it’s a UK bestseller
London users report it’s “perfect for my student room—compact, simple and cools fast.” It hits just the right chord of simplicity and performance without breaking the bank. Slim enough to tuck behind furniture; great for small homes.
Heads-up
Lower BTU means it struggles in larger rooms—stick to single bedrooms or office spaces.

Safety Tips During a UK Heatwave
- Hydrate in style: Carry a BPA-free bottle and drink even when not thirsty.
- Avoid midday madness: Between 12–4pm is the Mercedes-Benz of heat hours.
- Shade is your friend: Close curtains early to block that sun.
- Chill before bed: Pop your portable AC on 30 minutes ahead—cool room, calmer night.
Frequently Asked Questions (FAQ)
Q: Will these units run up my electric bill?
Not really. A 9 000 BTU unit draws about 1 kWh per hour on high, which costs roughly 26p/hour at current UK rates.
If you run it overnight in Eco or Sleep mode, expect to pay around 80p to £1.20 per night—far less than central air or running fans all day.
Q: Are they hard to move between floors?
They’re on wheels but heavier than they look (28–31 kg). Two people is safe, but once they’re on one floor most users just leave them there for the week.
Q: Do they actually reduce humidity?
Yes—all three remove several litres of water per day. The LEENON’s continuous drain option is super handy, and others auto-evaporate most of the condensate.
Q: Will my landlord mind?
Unlikely—no drilling, no fuss. If you’re still unsure, show them the window panel kit fits existing frames cleanly.
Q: Can I use them in old Victorian houses?
Absolutely. Users in historic buildings report the kits “sit flush without damaging sash frames”.
Final Thoughts — Which One Should You Buy?
- 💤 KGOGO: If you need whisper‑quiet nights with powerful cooling and value Sleep Mode above all.
- 🏡 LEENON: For those with bigger spaces, humidity issues or living in converted cellars—strongest coverage.
- 💷 Pro Breeze: Ideal if you’re after a compact, budget-friendly, no-nonsense unit with solid UK support.
