The renter's dehumidifier checklist

  1. Measure humidity with a hygrometer (£10).
  2. If above 60%: get a proper compressor (Products 1–4).
  3. If 55–60%: a mini (Product 5) or moisture absorber bags may be enough.
  4. If above 70%: get a dehumidifier AND report to your landlord.

How a dehumidifier protects your deposit

Mould damage is one of the most common deposit deductions

Landlords charge £200–£500 for mould cleaning, £500+ for repainting mouldy walls, and £1,000+ for replacing mould-damaged window frames. Once mould stains soft furnishings or carpet, the bill climbs faster still.

A £100–£200 dehumidifier running 6 hours/day costs £8–£12/month in electricity — far cheaper than losing your deposit, and you keep the appliance for the next flat.

Document your humidity readings as evidence that you took reasonable steps to prevent damage. A photo of your hygrometer next to a date on a phone screen is enough.

Tip

Keep the receipt

Keep the Amazon receipt for your dehumidifier and hygrometer. If a dispute reaches the deposit protection scheme, proof you bought damp-control equipment shows you acted as a reasonable tenant.
