Filing a Complaint About a Landlord in Wales: Step-by-Step Guide

If you're a renter in Wales experiencing issues like unreasonable rent increases, poor maintenance, or unfair eviction attempts, knowing how to formally complain about your landlord can feel daunting. This guide explains the Welsh complaint process in clear, practical steps. We'll highlight your rights as a tenant, point you to the right official channels, and link directly to government forms and legal sources. Our goal is to empower you with up-to-date, impartial information.

Understanding Your Rights as a Renter in Wales

Since December 2022, almost all renters in Wales have been protected under the Renting Homes (Wales) Act 2016. This law sets out your rights and your landlord's responsibilities, such as carrying out repairs and following eviction procedures. Whether you have a secure or standard contract, you have protections if your landlord isn't following the rules.

Steps to File a Complaint Against Your Landlord in Wales

1. Raise the Issue Directly with Your Landlord

Start by contacting your landlord or letting agent in writing. Explain the issue clearly and ask for a resolution. Keep copies of all correspondence, as these can support your case later.

2. Use Your Landlord's Official Complaints Process

All registered landlords in Wales should have a complaints procedure. Ask for details if it's not provided. Use this formal process and keep records of your submissions and responses.

3. Escalate the Complaint

  • For serious repair or safety issues: Contact your local council’s housing department. Councils have powers to inspect and intervene if the property is unsafe or not maintained properly. Find your council here.
  • Unfair eviction or contract issues: You may be able to challenge this at the specialist Residential Property Tribunal Wales (RPTW), which handles disputes over rent increases, evictions, and contract matters.
  • If your landlord is not registered or licensed with Rent Smart Wales: Report them to Rent Smart Wales.
  • Agent complaints: If you’ve gone through their complaints process and are still unsatisfied, consider contacting the relevant redress scheme (e.g., The Property Redress Scheme).

4. Applying to the Residential Property Tribunal Wales (RPTW)

For many housing disputes—like rent assessment, eviction notices, or contract disagreements—the official body handling residential tenancy complaints in Wales is the Residential Property Tribunal Wales.

  • Typical matters the Tribunal can deal with include:
    • Disputes over rent increases for standard contracts
    • Challenges to eviction notices
    • Failure to provide a written occupation contract

Action Steps for Renters Filing a Complaint

  • For tribunal applications, download and complete the relevant RPTW form. Attach your evidence and submit as instructed in the guidance notes.
  • Keep records of all your steps—these help at each stage.

FAQ: Complaints Against Landlords in Wales

  2. Who investigates complaints about landlords in Wales?
    Your local council handles housing and safety complaints. For rent, eviction, and contract disputes, the Residential Property Tribunal Wales deals with formal applications. Rent Smart Wales investigates registration or licensing breaches.
