Best portable air conditioners UK 2026

If you want the short answer: for most UK homes the strongest all-round portable air conditioners are the MeacoCool MC Series and the AEG ChillFlex Pro, with the DeLonghi Pinguino range the pick if quiet running matters most. These are genuine refrigerant units that vent hot air through a hose out of a window. They cool a real room, unlike the cheap "no hose" gadgets that are usually evaporative coolers and barely move the temperature in a humid British summer.

This guide ranks the portable models you can actually buy in the UK by use case and budget, gives the honest indoor noise figure for each on quiet mode, and then cuts through the marketing so you buy the right thing once.

Prices and availability were correct at July 2026 and change frequently, so check the retailer before buying. Portable air conditioner prices swing sharply between off-season and heatwaves, and the energy price cap changes quarterly, so always confirm the live price first.

Our top picks at a glance

Noise figures are indoor sound-pressure dB(A) on the lowest or sleep setting where the maker publishes one. Where only a sound-power dB figure is available it is labelled as such, and that number is not comparable with the dB(A) figures (see the noise section below). Prices and stock correct as of July 2026; re-check before buying.

Do "no hose" portable air conditioners actually work?

This is the single most important thing to understand before you spend a penny. A genuine refrigerant air conditioner has to send its waste heat somewhere, and that means a hose out of a window. It pumps heat out of the room. Run the same unit with the hose disconnected and it will heat the room, not cool it.

So a "portable air conditioner with no hose" is almost always something else: an evaporative air cooler. That is a fan blowing over a wet pad. It adds moisture to the air and drops the temperature by only a few degrees, and it works poorly in humid UK summers. AirconCentre states air coolers "are not suitable for extremely humid environments or areas with temperatures that exceed 30°C" and lower a room "by a maximum of a few degrees". Meaco puts it plainly: air coolers "work best in arid countries but are not very effective in Britain, where we have humid summers".

The handful of genuine no-hose compressor units, such as the Coolzy-Pro, get around the laws of physics by being tiny personal spot coolers (roughly 1,100 to 3,500 BTU), aimed at cooling the person rather than the room. The £30 to £40 "mini AC" and USB desk gadgets are evaporative coolers too, not air conditioners. If you want to cool a hot room, you want a hosed refrigerant unit. For the full breakdown, see our guide to portable air conditioners without a hose.

The best portable air conditioners, reviewed

MeacoCool MC Series 7000 (best overall)

A UK brand that turns up on every reviewer's shortlist, and the MC7000 is the value sweet spot for an average bedroom or home office.

Best for: single rooms up to around 18 m2 where you want a quiet, well-priced, no-fuss unit.

• It is a 7,000 BTU (roughly 2.0 kW) single-hose refrigerant unit with three functions: cool, dehumidify and fan.

• Indoor noise is 51 to 53 dB(A) on quiet mode (the unlabelled 65 dB figure you may see is sound power, not comparable).

• Energy rating A, R290 refrigerant, two window kits included, night mode and remote.

Pros: quiet for the class, genuinely portable, two window kits cover most windows, strong value.

Cons: 7,000 BTU is modest, so step up for larger or sunnier rooms; no heating, no WiFi.

Price: around £345 to £445. Last checked July 2026.

AEG ChillFlex Pro 12,000 BTU, AXP34U338HW (best for large rooms)

If you are trying to cool an open-plan space or a large, south-facing room, raw output matters and AEG's 12,000 BTU unit is the one reviewers reach for.

Best for: large rooms and open-plan spaces.

• 12,000 BTU of cooling, single-hose, R290.

• Around 52 dB(A) on sleep mode indoors.

• Energy rating A.

Pros: plenty of cooling power, reasonable sleep-mode noise for its size.

Cons: bigger and heavier than a 7k to 9k unit; cooling only.

Price: around £500. Last checked July 2026.

DeLonghi Pinguino EL112 / Care4Me (quietest)

DeLonghi's Pinguino is the most-recommended portable brand in the UK, and the smart EL112 (Care4Me) is the one to buy if a quiet bedroom is the priority.

Best for: light sleepers and bedrooms where noise is the deciding factor.

• 11,000 BTU, single-hose, R290, with WiFi, an app, voice assistant support and geofencing.

• Indoor noise is quoted at 46 to 53 dB(A) depending on speed, among the lowest in the class.

• Energy rating A+ (confirm against the manufacturer label, as DeLonghi ratings vary in retailer copy).

Pros: very quiet, genuinely useful smart features, strong dehumidification.

Cons: premium price; cooling only, no heating.

Price: £779 to £949. Last checked July 2026.

If you want DeLonghi quiet running for less, the entry-level PAC EM77 (9,000 BTU, around 47 to 50 dB(A) on quiet mode) sits at roughly £350 to £450, though stock was patchy at research time.

VonHaus High-Performance 9000 (best budget)

The pick when the priority is keeping the price under £300 and you can live with more noise.

Best for: a spare room or occasional use on a tight budget.

• 9,000 BTU, single-hose, three-in-one with WiFi and a window kit, 1,005 W.

• Energy rating A.

• Noise is quoted at 65 dB sound power. No indoor sound-pressure dB(A) on quiet mode is published, so treat it as a louder unit and not one for a sensitive sleeper.

Pros: a lot of cooling for the money, app control included.

Cons: noisy; sparse quiet-mode noise data.

Price: £259.99. Last checked July 2026.

Two budget alternatives that also heat: the Igenix IG9919 (9,000 BTU four-in-one with heating, around £289.99 on sale) and the Daewoo COL1579GE (12,000 BTU four-in-one with heating, £389.99). Both quote 65 dB sound power rather than a quiet-mode dB(A) figure.

electriQ AirFlex 14000 (best self-evaporating)

A high-output unit that recycles its own condensate, so in cooling mode there is little or no tank to empty.

Best for: large rooms where you do not want to babysit a water tank, and where you also want heating.

• 14,000 BTU cooling (around 4.0 to 4.1 kW) plus 3.2 kW heating from a heat pump, single-hose, R290.

• Self-evaporating in cooling mode, so condensate is vented as vapour through the hose.

• Energy rating A for cooling. Noise is quoted at 65 dB sound power; no quiet-mode sound-pressure dB(A) is published, so assume it is not a quiet unit.

Pros: powerful, heats as well as cools, minimal draining.

Cons: loud, large; WiFi only on the separate AIRFLEX15W variant.

Price: £449.97 (refurbished units appear from around £299.97). Last checked July 2026.

MeacoCool MC10000CH (best that also heats)

A portable that earns its keep year-round: it cools in summer and runs in reverse as a heater in the shoulder seasons.

Best for: a room you want to take the chill off in spring and autumn as well as cool in summer.

• 10,000 BTU cooling with reverse-cycle heating (around 9,000 BTU of heat), single-hose, R290.

• Around 53 dB(A) indoors on the lower setting (the 65 dB figure is sound power).

• Energy rating A, dehumidify mode, rooms 18 to 28 m2.

Pros: true reverse-cycle heating, MeacoCool's included window kits, solid value.

Cons: no WiFi; portable heating is electric-resistance-equivalent in cost, so not a cheap way to heat.

Price: £479.99. Last checked July 2026.

EcoFlow Wave 3 (best battery / off-grid)

The unusual one: a reverse-cycle portable that can run from an optional battery, for spaces with no convenient socket or for use away from home.

Best for: off-grid use, conservatories without a spare socket, garden rooms and similar.

• 6,100 BTU cooling and 6,800 BTU heating, R290, IP65 rated, app control, fast charging.

• Optional roughly 1,024 Wh battery for cord-free running.

• It carries no standard UK A-G energy label (it is battery and off-grid rated), and its quiet-mode dB is not confirmed from a primary source, so we do not state either.

Pros: runs off a battery, heats and cools, weatherised.

Cons: lower cooling output than mains units; expensive once you add the battery; limited published noise and efficiency data.

Price: £699 for the unit, £1,199 for the unit plus battery kit. Last checked July 2026.

How to choose a portable air conditioner

A few decisions get you to the right unit quickly.

• Match the BTU to the room. As a rough guide, convert BTU to kilowatts by dividing by 3,412 (so 9,000 BTU is about 2.6 kW). Portables vent some waste heat back into the room and are less efficient than fixed splits, so add roughly 10 to 15% to the figure you would use for a fixed unit. Our air conditioner BTU and room-size guide walks through the sizing.

• Single-hose vs dual-hose. Single-hose units (almost everything sold here) push room air out, which draws warm air back in through gaps and makes them a little less efficient. Dual-hose units take and return condenser air from outside and avoid that, but are rarer in the UK.

• Check the noise scale, not just the number. A unit listed at "65 dB" is usually quoting sound power, which sounds dramatic; the indoor sound-pressure figure on quiet mode is the one you actually hear, and it is much lower. See the noise section below.

• Decide if you need heating or smart control. Reverse-cycle models heat as well as cool. WiFi and app control are worth having if you want to start the unit before you get home.

• Self-evaporating saves hassle. In cooling mode most current mid-range units recycle condensate and vent it as vapour, so there is rarely a tank to empty. You only collect water on dehumidify mode.

What the noise figures really mean

Two different noise scales appear on portable air conditioner listings, and retailers often quote the higher one without saying so.

• Sound pressure dB(A) is what you hear at a normal distance. On quiet or sleep mode, good portables sit around 46 to 53 dB(A).

• Sound power dB is the total acoustic energy the machine produces and reads higher, typically 63 to 65 dB for the same unit.

They are not interchangeable, so never compare a 50 dB(A) sound-pressure figure with a 65 dB sound-power figure and conclude one is louder. Throughout this guide we have used the indoor sound-pressure dB(A) on quiet mode wherever the manufacturer publishes one, and flagged the units where only a sound-power figure exists. If low noise is the deciding factor for you, our round-up of the quietest portable air conditioners in the UK ranks the leading models by their verified quiet-mode figures.

How much does a portable air conditioner cost to run?

A typical 9,000 BTU portable draws around 1 kW. Using the Ofgem price cap of 26.11p/kWh (the Jul to Sep 2026 cap), the maths is straightforward:

• 1 kW for 1 hour = 1 kWh = 26.11p per hour.

• Run for 8 hours a day, that is about £2.09 a day, or roughly £63 a month at daily use.

AirconCentre quotes a broader real-world range of about 30 to 40p an hour for a 9,000 BTU unit once you account for higher-draw models and warm-up cycles, which works out at roughly £70 to £100 a month at 8 to 9 hours a day. An evaporative cooler, by contrast, draws around 0.1 kW and costs only a few pence an hour, but remember it barely cools a humid room. There is more detail in our air conditioning running costs guide.

Running costs correct as of July 2026 using the Ofgem cap of 26.11p/kWh (Jul to Sep 2026). The cap changes quarterly, so check the current rate before budgeting.

Do you need planning permission or an installer for a portable unit?

No, and this is a genuine advantage of portables over fixed split systems.

• No F-Gas installer. Plug-in portables are sealed, self-contained refrigerant units (usually R290 propane), so you do not need an F-Gas certified installer. You plug them in and vent through a window. That makes them well suited to renters.

• No planning permission. There is no external condenser fixed to the building, so permitted-development and planning rules for fixed units do not apply.

• No notifiable electrical or building work. A plug-in appliance does not trigger Part P or Part L.

The trade-off is performance and tidiness: a wall-mounted split system cools more effectively, runs more quietly and looks neater, but needs a qualified installer and, if it heats as well as cools, may need planning permission. If a portable is a stop-gap and you are weighing up the permanent option, compare local installers for a fixed quote.
