The best dehumidifiers for damp and condensation (November 2026)

Damp makes a home feel colder and feeds black mould. A dehumidifier costs a few pence an hour and dries laundry indoors far more cheaply than a tumble dryer. Our ranking and running costs.

Updated: November 2026Electricity: 26.32p/kWh (Ofgem price cap)
Quick answer: a compressor dehumidifier of around 200 W costs about 5.3p an hour; the low-energy Meaco MeacoDry Arete One 12L (151 W) about 4.0p. Our top pick is the Pro Breeze 12L/Day Dehumidifier. For cold garages or unheated rooms, choose a desiccant model.

How we ranked them
  • Running cost: What each one costs per hour and per month at the Ofgem price cap (26.32p/kWh). Watt for watt, every electric heater costs the same to run: the one that saves money is the right size and switches itself off.
  • Controls: Thermostats, timers, weekly schedules, eco modes and Wi-Fi score highest: they are what actually cuts the bill.
  • Safety: Tip-over and overheat protection, and splash protection (IP24) for bathrooms.
  • What buyers say: Amazon UK sales and what buyers repeat in their reviews, summarised in our own words. Newer models with few reviews score lower until they have them.

We don't test products at home: we combine manufacturers' specifications, Amazon UK listings and buyer feedback with the running-cost maths. How we compare.

Compressor or desiccant?

Drying laundry: dehumidifier or tumble dryer?

A dehumidifier in laundry mode in a small closed room dries clothes for a fraction of the cost of a tumble dryer, and stops the condensation that drying indoors causes.

Frequently asked questions

How much does a dehumidifier cost to run?

A typical 200 W compressor model costs about 5.3p an hour at the price cap: 8 hours a day for a month, about £12.63. With the humidity sensor it runs less.

What humidity should my home be?

Between 40 and 60 %. Above about 65 % you get condensation, mould and dust mites.

Does a dehumidifier make a room warmer?

Not directly, but dry air feels warmer and is quicker to heat. Desiccant models also give off a little heat.

Running costs use the Ofgem energy price cap, 1 October to 31 December 2026: average unit rate for electricity paid by Direct Debit (26.32p/kWh, standing charge 54.83p/day) and gas (7.97p/kWh). National averages; your region and tariff may differ. Prices on Amazon change: check the live price before you buy.
