Portable Air Conditioners Built for No Installation in the UK in 2025

Did you know you can cool your room quickly without drilling or complex setups? Learn how portable air conditioners with simple window venting offer efficient, quiet, and energy-saving relief—perfect for renters and anyone seeking hassle-free cooling this summer.

Understanding Portable Air Conditioners That Need No Installation

Although “no installation” suggests a plug-and-play experience, all portable air conditioners require exhaust venting to expel hot air. The primary installation step includes:

Connecting an exhaust hose to the rear of the unit.
Attaching the hose to a window vent kit that fits into a window opening and prevents warm air from re-entering.
Plugging the unit into a standard electrical outlet.

This arrangement:

Usually needs no tools or professional help.
Does not require drilling or permanent mounting.
Is temporary and easily removable when not in use.

Window vent kits typically cost between £15 and £20 if not included. Hose lengths usually vary from 1.5 to 1.8 metres, allowing some flexibility in positioning, though extending the hose too much can reduce efficiency.

Factors to Consider When Choosing a Portable Air Conditioner

BTU Ratings Compared to Room SizeBTU (British Thermal Units) indicate cooling capacity. Selecting a unit with a BTU rating suited to your room size ensures efficient performance:

Small rooms (up to 18 m²): 7,000–9,000 BTU
Medium rooms (18–30 m²): 9,000–12,000 BTU
Larger rooms (30–40 m²): 12,000–14,000 BTU

Calculate your room’s length multiplied by width in metres to estimate size.

Energy Efficiency and Running CostsSeek models with an energy rating of A or better. Portable air conditioners generally consume more electricity than fixed units. For example:

A 9,000 BTU unit may use approximately 990 watts per hour.
At typical UK electricity rates in 2025, this could cost around 20–27 pence per hour of use.
Using four hours daily over 60 days could total about £48–£62 annually, depending on exact consumption and tariffs.

Noise LevelsNoise output varies between models from around 50 dB (quiet fridge) up to about 65 dB (dishwasher noise). Lower noise models are generally better suited for bedrooms and study spaces.

Additional FeaturesCertain models may offer features like:

Remote control through apps or voice assistants.
Sleep and eco modes to reduce power and noise at night.
Self-evaporating technology that minimizes or eliminates water tank emptying.
Combination functionalities such as heating and dehumidifying.

Maintenance Tips for Portable Air Conditioners

To keep your portable AC efficient and extend its lifespan:

Clean or replace air filters every 2–4 weeks depending on use.
Check the exhaust hose and window seal regularly for leaks.
Drain condensate tanks as needed, unless the unit has a self-evaporating feature.
Keep the unit free from dust and debris.

Appropriate Uses and Drawbacks of Portable Air Conditioners

Suitable for:

Renters or those unable to drill holes in walls.
Temporary or seasonal cooling during warm periods.
Cooling individual rooms or small flats with flexible placement needs.

Limitations:

Generally less energy-efficient and noisier than fixed split air conditioning systems.
Not intended for whole-house or multi-room cooling.
The exhaust hose may be visible and impact the room’s appearance.

For those seeking permanent, quieter, and more energy-efficient cooling, fixed split systems are often preferable, though they usually need professional installation and a bigger upfront cost.
