Every autumn the same messages start arriving: black spots on the bedroom ceiling, streaming windows, a musty smell in the wardrobe. Choosing the best dehumidifier for a rental property won’t fix a leaking gutter or failed damp-proof course. It is, though, one of the cheapest and fastest tools you have for bringing condensation under control, protecting your decor and showing that you acted quickly when a tenant reported a problem.
This guide covers which type of dehumidifier suits which property, the models worth shortlisting, and how to supply one without creating new liabilities. It also explains why a dehumidifier supports your legal duties without discharging them. Under the Homes (Fitness for Human Habitation) Act 2018, damp that makes a home unfit is your problem to solve, whatever appliance is sitting in the corner.
Key takeaways
- A dehumidifier treats condensation well. It does not cure rising damp, penetrating damp or leaks, which are repairs you must carry out.
- Compressor (refrigerant) models suit heated homes. Desiccant models keep working in cold, unheated rooms.
- A 20-litre-a-day unit covers most two-to-four-bedroom lets. Small flats may only need 10–12 litres.
- Aim to keep indoor humidity at around 40–60%. A cheap hygrometer lets you and your tenant check it.
- Awaab’s Law already applies in social housing. It has not yet been brought into force for private rentals, but it is coming, so build a fast, documented damp response now.
Do landlords have to provide a dehumidifier?
No law in England requires you to supply a dehumidifier. What the law does require is a home that is free from serious hazards and fit to live in. Damp and mould growth is one of the hazards assessed under the Housing Health and Safety Rating System (HHSRS) in the Housing Act 2004. Since the Homes (Fitness for Human Habitation) Act 2018, tenants can also take you to court directly if serious damp makes the property unfit.
So the real question is whether a dehumidifier is the right remedy for your particular damp problem. If the cause is condensation from everyday living, such as drying clothes indoors, cooking and showering in a poorly ventilated flat, a good dehumidifier combined with better ventilation can solve it. If the cause is structural, the dehumidifier only masks it while the fabric of the building deteriorates. Our guide to landlord responsibilities for mould and damp explains how to tell the difference and what you are legally obliged to fix.
Where Awaab’s Law fits in
Awaab’s Law has applied to social landlords in England since 27 October 2025, starting with damp and mould. It sets strict timeframes for investigating and fixing hazards. The Renters’ Rights Act 2025 provides for extending it to private rentals, but the secondary legislation is not yet in force and the government has not set a start date. Commentators currently point to 2027 at the earliest. Read more in our explainer on Awaab’s Law and the Decent Homes Standard.
The practical lesson is to start behaving now as if the clock already applies. That means acknowledging damp reports promptly, inspecting quickly and keeping records. A dehumidifier delivered within days of a report is good evidence that you took the complaint seriously.
Our picks: the best dehumidifiers for rental properties
We have shortlisted popular, well-rated models from established brands that sell in the UK, choosing for the realities of a let rather than a showroom. That means models with an automatic humidity setting (so tenants can “set and forget”), a decent tank size, a continuous-drain option, auto-restart after a power cut, and a solid warranty.
Quiet, efficient, has an H13 HEPA filter and a 5-year warranty. It’s a strong “fit it and forget it” choice for family lets.
Large 5.5L tank, automatic humidity control and laundry mode at a budget-friendly price. Ideal for multiple units.
Desiccant technology keeps extracting in unheated rooms, so it’s useful during voids and in cold bedrooms.
A cheap way for you and your tenant to see whether humidity is staying in the 40–60% range.
1. MeacoDry Arete One 20L: best overall
Meaco is a British dehumidifier specialist, and the Arete One 20L is its flagship. It extracts up to 20 litres a day, doubles as an air purifier thanks to a medical-grade H13 HEPA filter, and is one of the quietest large dehumidifiers on the market. That matters because tenants switch noisy units off. It can sit flush against a wall and restarts with its settings intact after a power cut. It also comes with a five-year warranty, which is unusually long and valuable when the appliance lives in someone else’s home.
Best for: family homes and higher-rent lets where you want one reliable unit that tenants will actually leave running. Trade-off: it costs more upfront than budget models.
2. Pro Breeze 20L: best value
Pro Breeze is one of Amazon UK’s best-selling dehumidifier brands. Its 20-litre compressor model covers the essentials well. It has a 5.5-litre tank, so tenants empty it less often, and an automatic humidity sensor that holds the room around 40–60%. It also has a laundry mode for drying clothes indoors (the number one cause of winter condensation in rentals), a 24-hour timer and a continuous drain hose option.
Best for: portfolio landlords supplying several units, and single lets where budget matters. Trade-off: the standard model is louder than premium units, and the warranty is shorter.

3. Meaco DD8L Desiccant: best for cold or empty properties
Compressor dehumidifiers work by chilling air over a cold coil, and they lose much of their effectiveness when the room itself is cold. Desiccant units absorb moisture with an absorbent material and keep working at low temperatures. That makes them the better choice for a property sitting empty over winter, an unheated box room or a cold north-facing bedroom. They also give off a little warmth, which helps.
Best for: void periods, holiday lets closed for the season and cold rooms. Trade-off: it extracts less water per day and uses more electricity than a compressor model in a warm room.
Compressor vs desiccant: which type suits your property?
Compressor (refrigerant)
✓ High extraction in heated rooms
✓ Lower running cost when warm
✗ Struggles below ~15°C
Desiccant
✓ Works in cold, unheated rooms
✓ Lighter and quieter
✗ Uses more power in warm rooms
Hygrometer (add-on)
✓ Shows humidity at a glance
✓ Helps tenants manage condensation
✗ Measures only, doesn’t treat
As a rule of thumb, if the tenants heat the home normally, choose a compressor model. If the property is empty, or the damp problem is in a room nobody heats, choose a desiccant model. For sizing, a 10–12 litre unit suits a studio or one-bedroom flat with mild condensation. A 20-litre unit is the sensible default for two to four bedrooms or any property where laundry is dried indoors.

How to respond to a damp report: a step-by-step process
A dehumidifier works best as one step in a documented process, not as a reflex. This sequence protects your tenant, your property and your position if the matter ever reaches a council officer, the new Landlord Ombudsman or a court.
Responding to a damp report, step by step
Reply the same day, ask for photos and arrange an inspection visit.
Check for leaks, failed seals, blocked vents and wall moisture readings. Is it condensation or structural damp?
Leaks, gutters, extractor fans and ventilation are your responsibility. A dehumidifier is no substitute.
Set it to around 50% humidity and show the tenant how to empty and use it.
Clean affected areas, then check readings and photos. Record everything you did and when.
For step 2, a moisture meter is invaluable. It helps you separate surface condensation from moisture within the wall. See our round-up of the best damp meters for landlords. For record-keeping, our damp and mould evidence log shows how to document each visit, reading and conversation. The government’s official guidance, Understanding and addressing the health risks of damp and mould in the home, is also worth reading in full. It is explicit that landlords should not blame tenants’ “lifestyle” without first tackling the underlying causes.
Supplying a dehumidifier: the practical and legal details
Electrical safety
Once you provide an electrical appliance, you are responsible for it being safe. The five-yearly EICR required under the Electrical Safety Standards in the Private Rented Sector (England) Regulations 2020 covers the fixed installation rather than portable appliances. Even so, keeping the manual and proof of purchase, registering the warranty and having landlord-supplied appliances PAT tested at inspections is sensible practice, particularly in HMOs. Buy from established brands and reputable retailers rather than unbranded imports.
Put it in writing
Add the dehumidifier to the inventory with its make, model and condition, and confirm by email that you supplied it, when and why. Note that the tenant should report faults rather than attempt repairs. This creates a clear record that you responded to the damp report, and it avoids arguments at check-out about whose appliance it is.
Running costs and who pays
Where tenants pay the bills, the electricity to run the unit is theirs. Modern 20-litre compressor models typically cost in the region of 7–12p an hour to run at current tariffs, according to manufacturers’ figures. That is far cheaper than a tumble dryer, which is a useful point to make if a tenant is reluctant to keep it on. Never make running the dehumidifier a condition that shifts responsibility for structural damp onto the tenant. That would not stand up if the property were found unfit.
Common mistakes landlords make with damp and dehumidifiers
- Treating the symptom, not the cause. Dropping off a dehumidifier while a gutter overflows down the wall guarantees the mould comes back, and leaves you exposed if the council inspects.
- Buying too small. A 10-litre unit in a three-bed family home that dries its laundry indoors simply can’t keep up.
- The wrong type for the room. A compressor model in a cold, empty flat will barely fill its tank.
- Ignoring ventilation. Working extractor fans in the kitchen and bathroom, trickle vents and a heating regime matter just as much as the dehumidifier.
- No records. If you can’t show what you did and when, you can’t prove you acted promptly, and that matters even more once Awaab’s Law reaches private rentals.
Regular checks catch damp early, before it becomes a hazard. Our guide on how often landlords should inspect properties suggests a sensible schedule, with an autumn visit especially worthwhile.
Conclusion: a small cost that protects a big asset
Used properly, a dehumidifier is one of the best-value purchases a landlord can make. It controls condensation, protects decor and furnishings, keeps tenants healthier and happier, and demonstrates a prompt, responsible response to damp. For most lets, a quality 20-litre compressor model such as the Meaco Arete One, or the Pro Breeze 20L on a tighter budget, is the right choice. Keep a desiccant unit for cold rooms and empty properties. Always fix the cause first, and record everything you do. It is good practice today and is likely to become a legal expectation for private landlords.

Frequently asked questions
Is a landlord legally required to provide a dehumidifier?
No. There is no specific legal requirement. However, landlords must keep the property free from serious hazards, including damp and mould, and fit for human habitation. A dehumidifier can be part of a reasonable response to condensation, but it does not replace repairing the cause of structural damp.
What size dehumidifier does a rental property need?
A 10–12 litre-per-day unit suits a studio or one-bedroom flat with mild condensation. For two to four bedrooms, or any home where washing is dried indoors, a 20-litre unit is the sensible default.
Should I choose a compressor or desiccant dehumidifier?
Choose a compressor model for homes that are heated normally, because it extracts more water for less electricity in warm rooms. Choose a desiccant model for cold, unheated rooms or properties sitting empty, where compressor models lose effectiveness.
Who pays to run a landlord-supplied dehumidifier?
If the tenant pays the utility bills, they pay for the electricity. Modern 20-litre compressor models typically cost around 7–12p an hour to run according to manufacturers, which is far less than a tumble dryer.
Does Awaab’s Law apply to private landlords?
Not yet. Awaab’s Law has applied to social housing in England since 27 October 2025. The Renters’ Rights Act 2025 provides for extending it to private rentals, but no start date has been confirmed, and 2027 is widely cited as the earliest likely date.
What humidity level should a rental property be kept at?
Around 40–60% relative humidity is the commonly recommended range for UK homes. Persistent readings above 60–65% make condensation and mould much more likely. A cheap digital hygrometer lets you and your tenant monitor this.
Do I need to PAT test a dehumidifier I provide?
PAT testing is not a specific legal requirement for most single lets, but you are responsible for the safety of appliances you supply. Periodic PAT testing is recommended good practice, especially in HMOs.
