What are the best dehumidifiers to buy in the UK?
Our top pick for Dehumidifiers in the UK is the Pro Breeze 20L OmniDry WiFi Dehumidifier.
The Pro Breeze 20L OmniDry is the pick for most UK homes — its 20-litre daily extraction rate handles damp rooms and condensation effectively, and built-in WiFi control makes it easy to manage remotely during the UK's prolonged wet seasons.
Damp is a persistent problem in British homes. Victorian and Edwardian terraces, purpose-built flats and even newer builds suffer from condensation, rising damp and penetrating moisture — accelerated by the UK's consistently humid, cool climate. A dehumidifier extracts moisture from the air before it settles on cold walls and windows to form condensation mould. The key metric is extraction rate in litres per day, measured at a standard 30°C/80% relative humidity — real-world UK extraction in cooler rooms will be lower, typically 30–50% of the stated rate. For a standard UK bedroom or living room, 10–12 litres per day is sufficient; larger spaces like basements, garages or whole-house damp problems need 20L+ or a model with a continuous drain hose. Compressor dehumidifiers (the most common type) work best at temperatures above 15°C — for cold UK garages and loft spaces in winter, a desiccant dehumidifier performs more reliably.
Buying guide
What should you look for in Dehumidifiers?
1Match extraction rate to room size and UK conditions: Stated extraction rates (litres/day) are measured at 30°C/80% RH — conditions rarely found in a UK home. In a typical UK living room at 18°C, expect 40–60% of the stated rate. A 12L/day model delivers roughly 5–7 litres per day in real UK conditions — adequate for a bedroom or bathroom. For damp basements or garages, choose 20L/day or above.
2Compressor vs desiccant for UK winters: Compressor dehumidifiers (most models in this list) lose efficiency below 15°C and can freeze up below 5°C. If your dehumidifier will sit in an unheated UK garage, utility room or loft in winter, choose a desiccant model instead — these use a silica gel rotor and work effectively down to 1°C.
3Continuous drain hose saves daily emptying: A gravity-fed drain hose routes collected water directly to a sink or drain — eliminating the need to empty the tank every 1–2 days. Essential for UK basements or utility rooms where the dehumidifier runs continuously. Check the hose is long enough to reach a drain from where you plan to position the unit.
4Laundry drying mode is a UK essential: UK households dry laundry indoors for 6–9 months of the year. A dedicated laundry drying mode runs the dehumidifier at full power while directing airflow towards clothes on an airer — significantly cutting drying time and reducing the associated mould risk from wet clothes hung indoors.
5Check noise level if the unit will run in living spaces: Compressor dehumidifiers generate noise from their compressor and fan. Under 40 dB is quiet enough for a bedroom on sleep mode; 45–50 dB is noticeable in a quiet room. Most UK buyers keep dehumidifiers in utility rooms or hallways — but if placing in a bedroom or living room, noise level matters.
Our process
How do we choose our picks?
We don’t lab-test products ourselves. Instead we synthesise current Amazon UK listings and published specs into clear, honest recommendations. We earn a commission if you buy through our links, but that never changes which products we rank.
Current UK availability
We check each pick against live Amazon UK catalogue data rather than last year’s model lists. Stock moves fast, so a listing can sell out after we publish.
Published specs
We compare manufacturer specifications so each pick is right for a real budget and use-case.
UK-specific fit
We factor in UK voltage and plug/fitting standards — details that generic global lists miss.

Editor's Note
Dehumidifiers sold in the UK must carry UKCA or CE marking and comply with BS EN 60335-1 (domestic appliance safety standard). Under the Consumer Rights Act 2015, UK buyers have up to six years to claim for faulty goods. The UK has no mandatory energy rating label for dehumidifiers (unlike washing machines or fridges), so compare wattage figures and extraction rates directly — a lower watt-per-litre ratio means better efficiency. Compressor dehumidifiers use refrigerant — post-Brexit, UK regulations follow the F-Gas Regulation (retained in UK law) which restricts high-GWP refrigerants; R290 (propane) is an approved low-GWP alternative. If mould is already present on UK walls, it requires physical treatment (dilute bleach or specialist mould spray, then repainting with anti-mould paint) — a dehumidifier prevents recurrence but does not remove existing mould spores from surfaces. UK local councils can issue improvement notices for landlords where mould constitutes a health hazard under the Housing Health and Safety Rating System.
Our Take
UK appliances run on 230V and need to fit standard kitchen cavities — always check dimensions before ordering. The Pro Breeze 20L OmniDry WiFi Dehumidifier is our top recommendation — 20L/day extraction with WiFi control and a continuous drain hose. The Pro Breeze 12L/Day Dehumidifier with Humidity Sensor is the smart budget pick — it covers the essentials without the premium price tag. Avoid the cheapest unbranded options on Amazon UK — UK consumer protection only helps if the seller is still trading.
Questions & answers
Frequently asked questions
What size dehumidifier do I need for a UK home?
For a standard UK bedroom or bathroom with condensation on windows, a 10–12 litre/day dehumidifier is sufficient. For an open-plan living area or a flat with widespread damp, choose 16–20 litres/day. For a UK basement, garage or a Victorian terrace with penetrating or rising damp, a 20L/day or larger model with a continuous drain hose is recommended. Remember that stated extraction rates are measured at 30°C/80% RH — UK real-world performance will be 40–60% of this figure.
Should I get a compressor or desiccant dehumidifier for a UK home?
A compressor dehumidifier is the best choice for heated UK living spaces (above 15°C) — it is more energy-efficient and extracts more moisture per kWh than a desiccant model. A desiccant dehumidifier is better for cold unheated UK spaces like garages, lofts or utility rooms in winter, as it works effectively down to 1°C while compressor models lose efficiency and can freeze below 5°C.
How do I get rid of black mould in a UK home?
Treat existing black mould with a dilute bleach solution (1 part bleach to 4 parts water) or a specialist mould remover, scrub the surface and repaint with anti-mould paint. A dehumidifier prevents mould returning by keeping indoor relative humidity below 60% — the threshold above which mould spores germinate. Ventilation is equally important: open windows when cooking and showering, and use extractor fans. If mould is extensive or covers structural walls, consult a damp specialist — this may indicate rising or penetrating damp requiring physical remediation rather than humidity control alone.
