Compact Domestic Dehumidifier Hire London | 20L 230V for Homes & Flats

No. This unit is built for one room at a time — up to about 50 m². If you need to dry multiple rooms, a studio flat, or a whole house, you’ll want the 38L commercial or one of our industrial units. Call us and we’ll tell you which size fits your situation.

Not in the real world. That figure comes from a lab test at 30°C and 80% humidity — basically tropical conditions. A normal UK room at 18-22°C is cooler and less humid, so the unit won’t hit that number daily. Think of “20L” as the size class. It tells you this is a compact domestic unit, not an industrial one.

In most cases, yes. Condensation forms when the air is too humid and hits a cold surface like a window. This unit pulls moisture out of the air, so there’s less of it to condense. Most customers see a noticeable difference within 2-3 days. Keep the room door closed while it’s running so it’s only working on that one room.

Yes, if the leak has been fixed and any standing water has been mopped up. Put the unit in the affected room, close the door, and let it work. For soaked floors, multiple rooms, or cold spaces, you’ll need something bigger — call us and we’ll recommend the right size.

It can help, in the right conditions. If the room is warm (above about 18°C), ventilated, and you’ve only replastered a small area, this unit will lower the humidity around the plaster and help it dry faster. For cold rooms, large plastering jobs, or tight contractor deadlines, you’ll need a 38L or industrial unit.

Most people say yes. At around 48 dB it’s roughly the same volume as a fridge. If you connect the continuous drain hose (where supplied), it won’t wake you up by beeping when the tank is full.

A normal UK 3-pin plug. Same socket as a kettle or a lamp. No special wiring, no adapters, no electrician needed.

Yes, a continuous drainage option is typically available (where supplied with the unit). You connect a hose to the back and run it to a drain or sink. The golden rule: the hose must run continuously downhill, with its end sitting LOWER than the outlet on the machine — gravity does the work, so any uphill section or kink stops the flow and the tank takes over. Avoid draining into a bucket where you can (an unwatched bucket overflows); if you must, use a large one and check it often. Set up correctly, it can run unattended or overnight.

The dehumidifier, ready to plug in and run. A continuous drain hose may be supplied where available. No assembly needed. If you’re not sure what comes with it, ask us when you book.

No. A dehumidifier pulls moisture from the AIR — it cannot suck up puddles or soaked carpet. Remove standing water first with a wet vac or mop, then let the dehumidifier handle the moisture that is left in the air and materials. We hire wet & dry vacuums if you need one.

No. Lower humidity helps stop mould coming back, but it will not clean mould that is already there — that needs treating separately, and the moisture source needs fixing. Think of the dehumidifier as prevention, not cure.

Yes — after showering, not during. Keep the unit and its plug well away from splashes and standing water, run it with the door closed, and it will clear steam and condensation quickly.

Plug it straight into a wall socket where possible. If you genuinely need an extension, use a fully unwound, properly rated lead in good condition — and keep it off any damp floor.

For soaked carpets, wet floors or damp walls after a leak — often yes. The air mover pushes moisture out of the surfaces into the air, and the dehumidifier collects it. For everyday condensation, the dehumidifier alone is fine.
