Dehumidifier Running Costs: How Much to Run One (UK 2026)
Running cost is one of the most common questions about dehumidifiers, and the honest answer is: it depends. Here is what actually drives the cost and how to keep it down, without relying on vague 'low energy' marketing.
What drives the cost
Three things: the model's power draw (watts), how many hours it runs, and your electricity tariff (pence per kWh). A compressor model in a warm room generally costs less to run than a desiccant model, which uses a heater. The single biggest lever, though, is run time.
How to cut running costs
Use the humidistat: set a sensible target (45 to 55% humidity) so the unit switches off once the air is dry enough, rather than running all day. A timer helps too, for example running it while you dry laundry or overnight, then stopping. Keeping doors and windows closed in the room means it reaches the target faster and runs for less time.

Frequently asked questions
How much does it cost to run a dehumidifier?
It depends entirely on the unit's wattage, how long it runs and your tariff, so check the stated power rating rather than a fixed figure. A humidistat that switches it off at the target humidity is the best way to keep the cost down.
Should I leave it on all the time?
No need. With a humidistat it can cycle on only when humidity rises, which is far cheaper than running constantly. Continuous running is only worth it while tackling severe damp.
