Buying Guide
Cooling capacity and room size
Choose a unit with the right cooling output for the rooms you want to cool — portable air conditioners are rated in kW or BTU. For a small family living room or open-plan area you’ll typically need around 2.5–4 kW (8,500–14,000 BTU); undersizing means poor performance, oversizing wastes money.
Energy efficiency and running costs
Look at the energy efficiency (EER or kW per kW input) and fan modes — more efficient models cost less to run during hot spells. Consider estimated running costs in GBP, especially if you plan several hours’ use each day, and check for eco or night modes and programmable timers.
Venting, installation and window kit
Portable ACs need to exhaust hot air through a window or via a vent hose; single-hose units are simpler but less efficient than dual-hose designs. Check the included window kit fits your sash or casement windows, and confirm whether drilling or permanent changes are required (important if you rent).
Noise levels and placement
Noise is a major factor for families — check the declared dB(A) levels at different fan speeds and read reviews for real-world noise. Place the unit where it won’t disturb sleep or conversation; quieter models are worth paying for if you’ll run them in bedrooms.
Features, portability and maintenance
Look for wheels, handles, a remote or app control, built-in dehumidifier and washable filters for family convenience. Consider ease of draining condensate (self-evaporating vs manual drain) and accessibility of filters for cleaning to keep performance high.
Frequently Asked Questions
What is the best portable air conditioner in 2026?
There’s no single ‘best’ model for everyone, but by 2026 the leading choices for small families are mid-range units from De'Longhi and Meaco that balance cooling power (around 3 kW), low noise and good energy efficiency. Shop at UK retailers such as Currys, John Lewis or AO, and compare user reviews for real-world performance.
Is a portable air conditioner worth buying in the UK?
Portable air conditioners can be worth it for flats or homes without central air, occasional hot spells, or when you need a temporary solution (for example, during summer rentals). Bear in mind they’re less efficient than split systems and can increase electricity bills, but they’re cheaper to buy and easy to move between rooms.
Which portable air conditioner offers the best value for money?
Best value tends to be offered by mid-range models that combine about 2.5–3.5 kW cooling, reasonable noise (around 45–55 dB), and good energy efficiency. Brands such as De'Longhi and Trotec often provide the best balance of features, reliability and cost in the UK market.
De'Longhi vs Meaco — which should I buy?
De'Longhi typically focuses on quieter operation and user-friendly features, while Meaco models often emphasise energy efficiency and dehumidification. Choose De'Longhi if noise and convenience matter most; pick Meaco if running costs and humidity control are priorities.
How do I size a portable air conditioner for my home?
Measure the floor area and ceiling height of the room(s) you want to cool; for a typical small-family living room (about 20–30 m²) aim for roughly 2.5–4 kW (8,500–14,000 BTU). Adjust upwards for high ceilings, lots of glazing, or sunny rooms, and downwards for shaded or well-insulated spaces.
How much will a portable air conditioner add to my electricity bill?
Running costs vary by unit efficiency and usage, but expect roughly £0.10–£0.30 per hour for a mid-range portable unit, so heavy use during a hot week could add £20–£60 to your monthly bill. Using eco modes, timers and only cooling occupied rooms will keep costs down.
Can I use a portable air conditioner in a rented flat?
Yes, portable air conditioners are a popular option for renters because they don’t require permanent installation. Ensure the window kit won’t damage frames and check your tenancy agreement — landlords may have restrictions on blocking windows or altering ventilation.
