Best dehumidifiers UK (2026)
Compressor picks that actually stop condensation — sized by room, costed by the hour, verified in stock.
TL;DR
Most homes: the Pro Breeze 20L OmniDry — a Which? Best Buy with the capacity to dry laundry and hold a whole flat at 55% humidity.
Bedrooms & quiet running: the MeacoDry ABC 12L — the quietest compressor unit we know of, and Meaco’s support is the best in the business.
How big a dehumidifier do you need?
UK homes mostly need less than people buy. A 12L/day compressor unit holds a 1–2 bed flat dry; 20L/day covers a 3–4 bed house or heavy laundry-drying. The number is extraction capacity in tropical test conditions — in a real UK winter you’ll extract a fraction of it, which is normal and fine. What matters more: a humidistat (so it switches itself off at your target), a laundry mode, and continuous-drain option if it’ll live somewhere you won’t visit daily.
Running cost honesty: a modern 12L compressor unit draws roughly 160–200W while running — about 5p an hour at a 27p/kWh tariff — and the humidistat means it only runs when needed. A damp house is also harder to heat: drying the air genuinely reduces heating cost, so a dehumidifier partly pays for itself.
Pro Breeze 20L OmniDry
- 20L/day compressor
- Which? Best Buy
- Laundry mode
- Continuous drain
- Humidistat
The Which? Best Buy badge is on the listing for a reason: this is the whole-house option that dries laundry overnight, holds a target humidity without fiddling, and costs pennies per hour to run thanks to the auto cut-off.
It’s the pick if condensation is a house-wide problem or you dry washing indoors all winter. Too much machine for a single damp bedroom — that’s where the Meacos below earn their place.
£179.99MeacoDry ABC 12L
- 12L/day compressor
- Ultra-quiet (~35dB)
- Laundry mode
- Lightweight
Meaco built its reputation on this range: genuinely bedroom-quiet, simple controls, and the best customer support in the category. 12L handles a flat or the damp end of a house without breaking a sweat.
Choose it when noise matters — bedrooms, home offices, evening living rooms. The silver version below is identical inside if the price gap swings that way on the day.
£149.95MeacoDry ABC 12L (Silver)
- 12L/day compressor
- Identical spec to the white ABC
- Ultra-quiet
Amazon prices the two colourways independently and they regularly diverge — check both buttons and take the cheaper one; the machine is identical.
This is a genuine money-saving quirk of Amazon listings rather than a different product.
£149.95Meaco Arete One 12L
- 12L/day compressor
- HEPA air purifier built in
- Very quiet
- Award-winning design
The Arete adds a proper HEPA purifier to the dehumidifier — one machine for damp and allergies both, and it’s the model Meaco themselves treat as the flagship.
Worth the premium over the ABC if air quality matters in your home (allergies, urban pollution, pets); skip it if you purely want dry windows.
£179.99Pro Breeze 12L
- 12L/day compressor
- Humidity sensor + display
- Sleep mode
The value route into a proper compressor unit — same fundamental tech as the pricier picks with a plainer shell and a bit more fan noise.
Right for a first dehumidifier or a second unit for the other end of the house.
£134.99Compressor vs desiccant — the 30-second version
Everything above is a compressor unit: cheapest to run in normal UK indoor temperatures (10°C+), which is why they’re our default. Desiccant units win only in genuinely cold spaces — garages, conservatories, boats — where compressors lose efficiency; they run warmer and cost more per hour. If you’re drying a heated home, buy compressor and don’t look back.

Frequently asked questions
What size dehumidifier do I need for a UK house?
A 12L/day compressor unit covers a 1–2 bed flat; 20L/day covers a 3–4 bed house or heavy indoor laundry drying. Capacity ratings are from warm test conditions, so real UK extraction is lower — that's normal for every brand.
How much does a dehumidifier cost to run?
A modern 12L compressor unit draws roughly 160–200W when running — about 5p per hour at a 27p/kWh tariff — and a humidistat means it only runs when humidity is above target. Drier air is also cheaper to heat, offsetting part of the cost.
Will a dehumidifier stop condensation on windows?
Yes — streaming windows mean indoor humidity is too high, and holding 50–60% relative humidity with a dehumidifier stops most condensation at its source. Pair it with brief daily ventilation for the fastest results.
Compressor or desiccant for a UK home?
Compressor, in almost every heated home — cheaper per litre extracted at normal indoor temperatures. Desiccant only wins in cold spaces like garages and conservatories below about 10°C.
