Mold and Damp: Your Rights as a Renter in Northern Ireland

Mold and damp can make your rental home feel unhealthy and uncomfortable—and in serious cases, they may even cause illness or damage belongings. In Northern Ireland, renters are protected by clear rules that place most responsibilities for these issues on landlords. This guide explains your rights, how to report problems, when to escalate complaints, and what official steps you can take if repairs aren’t made.

Understanding Mold and Damp: What Are Your Landlord’s Duties?

Under the Private Tenancies (Northern Ireland) Order 2006, landlords must make sure your home is "fit for human habitation." This includes addressing serious mold or damp that can put your health at risk. The law requires landlords to:

  • Keep the structure and exterior in good repair (including walls, roof, windows and doors)
  • Maintain heating, plumbing and ventilation systems
  • Address persistent mould or damp that affects your living conditions

Minor condensation or spots that can be resolved by ventilation might not qualify, but major, ongoing issues should be fixed by your landlord.

How to Report Mold or Damp Problems

It’s important to report issues as soon as possible. Here’s a clear process to follow:

  • Document the problem: Take clear photos, and note when and where the damp or mould occurs.
  • Tell your landlord in writing: Email or send a letter describing the issue and asking for repairs. Keep a copy of all communications.
  • Request repairs: If your landlord does not reply within a reasonable time, remind them of their legal responsibilities under the Private Tenancies (NI) Order 2006.
If you’re not sure why you have mold or damp, you could request an inspection from your local council’s Environmental Health department.

What to Do If Your Landlord Won’t Help

If repairs are ignored, you have further options:

  • Contact your local council’s Environmental Health Team. They can inspect your home and, if needed, serve a notice on your landlord to make repairs, especially if the property is unsafe or affecting health.
  • Apply to the Northern Ireland Courts and Tribunals Service. The tribunal can resolve disputes between tenants and landlords, including those related to disrepair.

Official Forms for Complaints and Repairs

  • Private Tenancy Complaint Form (no number): Use this form to report a repair issue to your local council if your landlord hasn’t resolved the problem. You’ll need to describe the issue, provide evidence (photos, messages), and specify what action you are requesting. Access the Private Tenancy Complaint Form here.
  • Environmental Health Complaint Form: Used where mold or damp affects your health or the safety of the property. This can be requested from your council (links to local environmental health teams are available on the nidirect local council finder).

Once you submit a form, the council will usually contact you to arrange an inspection. If they find your landlord is responsible, they may issue an improvement notice requiring repairs.

Taking Your Complaint to a Tribunal

If your landlord still won’t address serious mold or damp after a council investigation, you may be able to refer your case to the official residential tribunal in Northern Ireland: the Northern Ireland Courts and Tribunals Service.

  • To start a case, use a Landlord and Tenant Application Form, stating your concerns and supplying evidence of the unresolved problem. Find tribunal forms and procedures here.
  • The tribunal can order your landlord to carry out repairs or even award compensation in some cases.

This step is usually only necessary after local authority action has failed to get results.

Keep detailed records of all issues, requests and responses—these will help if you need to go to the council or a tribunal.

Summary of Your Rights

In Northern Ireland, your landlord has clear duties to sort out serious mold and damp. If they won’t help, you can request council intervention, submit official complaint forms, and—if necessary—take your case to the Northern Ireland Courts and Tribunals Service.

Frequently Asked Questions

  1. Is my landlord always responsible for damp and mold?
    Landlords must fix issues caused by repair problems (like leaks, broken heating, poor ventilation or faulty insulation). However, if damp is caused only by tenant actions (such as drying clothes without ventilation or not heating rooms), the landlord may not be responsible.
  2. How soon does my landlord have to fix the problem?
    There’s no set legal timeframe, but landlords should respond promptly. For urgent issues affecting your health, repairs must be prioritised. If problems are ignored, you can escalate to your local council.
  3. Will reporting mold or damp lead to eviction?
    Your landlord can’t legally evict you just for reporting repairs. Any attempted "revenge eviction" can be challenged through the tribunal and council using your evidence of requested repairs.
  4. What if my belongings are damaged by mold?
    You may be able to claim compensation via the tribunal or small claims court if the landlord’s neglect caused the damage. Keep evidence and seek advice first.
