Your Rights for Mold and Damp Repairs in Wales

Repairs, Maintenance & Housing Standards Wales 4 min read · published March 09, 2026 Flag of Wales

Dealing with mold and damp in a rented home can be challenging, especially in Wales where the climate and some older properties can contribute to persistent problems. This guide explains your rights and options as a renter in Wales if you are coping with issues like damp, condensation, or mold, so you can get safe, healthy housing.

Understanding Your Legal Rights Around Damp and Mold

In Wales, landlords have clear legal duties to make sure your home is free from serious hazards, including exposure to damp and mold. Under the Renting Homes (Wales) Act 2016, landlords must keep the property in a state that is fit for human habitation throughout your tenancy, and that includes addressing damp problems.

Fact: Landlords must address damp and mold promptly under the Renting Homes (Wales) Act 2016 and housing safety rules. Keep records of all communications, repairs requested, and dates.
  • Your landlord must fix structural problems or issues that lead to mold or damp, such as leaks, rising damp, or poor insulation.
  • You are responsible for using heating and ventilation appropriately, but you are not responsible if mold is caused by factors outside your control.
  • If mold or damp makes your home seriously unhealthy, it may be classed as a ‘hazard’ under the Housing Act 2004.

If your landlord fails in these duties, you have formal steps you can take to ensure repairs are made.

Tip: Document the health effects with dates and photos and keep a written timeline of events to support your case.

Steps to Take if You Have Mold or Damp Problems

Always try to resolve issues with your landlord first, but use these steps if you need to escalate your complaint:

1. Report the Problem to Your Landlord

  • Notify your landlord in writing about the damp or mold. Clearly describe the problem and how it affects your health and the condition of the home.
  • Keep a copy of all correspondence.
  • Give your landlord a reasonable time to fix the issue (usually 14–28 days unless it’s urgent).

2. Use the 'Fitness for Human Habitation' Process

  • If repairs aren’t made, you can take action under the Renting Homes (Wales) Act 2016.
  • Contact your local council’s environmental health department—they may inspect your home for hazards.
  • If needed, the council can serve an Improvement Notice on your landlord, requiring repairs.

3. Applying to the Tribunal

  • You may apply to the Residential Property Tribunal Wales if your landlord refuses essential repairs.

Relevant Official Forms

  • Improvement Notice (Housing Act 2004, Part 1): Issued by your local council if hazards are identified. You don't submit this form yourself, but you can report the issue to your council online here and they will initiate this process if appropriate.

If your landlord serves you a 'possession notice' (eviction notice) after you report repairs, this could be considered unlawful 'retaliatory eviction'. Welsh law gives you added protection against this kind of eviction under section 217 of the Renting Homes (Wales) Act.

Prevention and Quick Actions

Some mold and condensation can be prevented day-to-day. Simple steps include:

  • Open windows regularly to improve ventilation
  • Use extractor fans in kitchens and bathrooms
  • Inform your landlord about any leaks or water ingress immediately
If you’re unsure whether you or your landlord are responsible for fixing damp, contact your council or a renters’ advice service for help.

Summary

Addressing mold and damp promptly can protect your health and rights. Don’t delay in reporting the issue and taking further steps if your landlord doesn’t act.

Insight: Acting quickly reduces health risks and helps build a clear timeline for a tribunal or council action. Keep a dated record of all communications, health symptoms, and responses.
