Dehumidifier Hire London | Heavy-Duty Drying for Homes & Flats (38L/Day)

It is commonly used for damp rooms, post-leak drying support (where the source has been resolved), plaster drying support in heated rooms, refurbishment work, studio flat dry-outs and small commercial spaces such as offices and shops. It is approx. 63 dB and commonly used in occupied properties, and runs from a standard 230V plug.

Yes, where the leak source has been fixed and surface water has been cleared. Place the unit in the affected room, close the door, and consider pairing with an air mover. For multi-room leaks, soaked floors or whole-property situations, a higher-capacity option such as the 43L Cube or 63L LGR may be more suitable. Drying time depends on room size, temperature, ventilation and moisture level.

It is commonly used for plaster and refurbishment drying support in heated, ventilated rooms (typically above ~15°C) by helping to reduce humidity around wet plaster or paint. For cold rooms, larger jobs or fast contractor schedules, our industrial or LGR options may be more suitable. Drying time depends on temperature, ventilation, plaster thickness and original moisture level.

It varies. Drying performance depends on room size, temperature, ventilation, moisture level, the cause of the damp and whether the source has been resolved. Indicative single-room recovery often falls within several days under suitable conditions, but we don’t guarantee specific drying times. Speak to us if you’d like advice on sizing for a deadline.

The 38L commercial unit may not be enough where the affected area is multi-room, soaked, very cold (below ~15°C) or part of a fast contractor schedule. In those situations a higher-capacity refrigerant or LGR option may be more suitable depending on conditions. We’re happy to help size it with you over the phone.

Yes. The Broughton CR40 has a standard hose connection for continuous drainage. Connected to a sink, gully or floor drain, continuous drainage can support longer unattended runs where set up with a suitable drain.

No. It runs from a standard UK 230V socket — the same outlet you’d use for a kettle. No special wiring required.

It can help reduce the humidity conditions that contribute to mould growth, but it does not remove mould directly. Existing mould patches still need cleaning separately. The cause of any structural damp should be addressed by a suitable professional. Results vary depending on room conditions.

Not typically. The 38L commercial unit is sized for a larger room, studio flat or small commercial space — not for whole-property drying. For whole-property recovery, look at our 63L LGR or 70–90L Building Dryer options. Speak to us before booking if unsure.

It is rated at approximately 63 dB — designed for use in occupied properties where noise is acceptable, and quieter than many commercial-class units. It uses electric operation, with no combustion fumes. Confirm placement at the time of booking if noise is a key consideration.

Dehumidifier hire rates vary by capacity and hire duration. The 38L commercial dehumidifier is available from Hireload with flexible daily and weekly hire options. Select your dates at checkout to see your total. For most post-leak, damp room or plaster drying jobs lasting 1-3 weeks, hiring is significantly cheaper than buying a commercial unit outright (typically 800 to 2,000). Running costs are approximately 3-6 per day in electricity.

For one-off jobs (post-leak drying, plaster support, damp flat recovery), hiring almost always makes more sense. You get a commercial-grade unit that extracts significantly more moisture than a domestic dehumidifier from a shop, and you return it when the job is done with no storage, maintenance or depreciation costs. Buying only makes sense if you have a permanent, ongoing moisture problem and plan to use the unit regularly for months or years.

Reducing indoor humidity to around 45-55% relative humidity can help reduce condensation on windows and walls and may help create less favourable conditions for dust mites and mould spores, which are common allergy triggers. A dehumidifier helps manage humidity levels but does not treat allergies directly. For persistent condensation, identify the root cause (poor ventilation, cold bridging, excess moisture sources) alongside using a dehumidifier.
