Tenants often discover damp or mould in rented homes and need clear steps to protect their health and housing rights.

You will learn how to report problems, keep records, and escalate issues to local environmental health or the tribunal if necessary. The advice is written for renters and leaseholders who want plain language steps, example letters, and links to official forms and enforcement bodies in Wales, so you can resolve damp problems quickly and safely.

What landlords must provide

Under the Renting Homes (Wales) Act landlords are generally responsible for keeping the structure and exterior in repair and ensuring homes are fit for human habitation in Wales. See the Act for duties and definitions.[1]

Landlords must address defects that cause damp or mould, provide adequate heating and ventilation, and carry out repairs within a reasonable time after notification.[3]

  • Report the damp to your landlord in writing and keep a copy of the message and any reply.
  • Take dated photographs and keep a log of mould growth, symptoms and any health effects.
  • Improve ventilation where safe to do so and protect possessions from further damage.
  • Give the landlord a reasonable time to inspect and start repairs after reporting; ask for confirmation in writing.
Keep all rent receipts organized and stored safely.

How to escalate if repairs are delayed

If the landlord does not act, you can contact your local authority environmental health team to request an inspection and enforcement in Wales.[3]

You can also apply to the First-tier Tribunal (Property Chamber) for orders or remedies; the tribunal handles residential tenancy disputes in England and Wales.[2]

  • Contact environmental health at your local council and submit a housing complaint with photos and the landlord correspondence.
  • Apply to the First-tier Tribunal (Property Chamber) if the issue is not resolved; keep copies of all evidence.
  • Consider seeking a rent reduction or compensation if repairs are unreasonably delayed; get legal advice where needed.
Respond to legal notices within deadlines to avoid losing rights.

FAQ

What counts as damp or mould that the landlord must fix?
Damp that results from disrepair, leaks, or defects affecting habitability should be fixed by the landlord; condensation from everyday living is different but landlords must advise on prevention.
How long should I wait for repairs?
There is no fixed national deadline; landlords must act within a reasonable time depending on severity. For urgent health risks, contact environmental health straight away.
Can I withhold rent if damp is not fixed?
Withholding rent is risky and can lead to eviction. Seek advice and consider formal routes such as local authority complaints or tribunal applications instead.

How-To

  1. Write to your landlord describing the damp, include dates and photos, and keep a copy.
  2. Gather evidence: dated photos, medical notes if relevant, and a log of communications.
  3. Contact your local council environmental health if the landlord fails to act and request an inspection.
  4. File an application to the First-tier Tribunal (Property Chamber) if the problem remains unresolved.
  5. Keep copies of all outcomes and consider asking for a rent reduction or compensation through the tribunal process.
