Landlord Prosecution in Wales: What Renters Need to Know

Landlord Duties, Licensing & Penalties Wales 5 min read · published March 09, 2026 Flag of Wales

If you rent a home in Wales and are worried about your landlord breaking the law, it’s important to know what legal protections exist and when a landlord could actually be prosecuted. This guide explains, in plain language, what landlord prosecution means, which laws in Wales apply, and what official action renters can take if their landlord fails in their legal duties.

Can a Landlord Face Prosecution in Wales?

Yes, landlords in Wales can be prosecuted if they break certain housing laws. Prosecution usually means taking the landlord to court, and it can lead to fines or even banning orders preventing them from renting out properties. Common reasons for prosecution include serious health and safety failures, renting without a licence, or repeated non-compliance with official improvement notices.

Keep a file of key documents (tenancy agreement, safety certificates, notices served, and photos of hazards) and note dates you reported problems. If you may pursue enforcement, contact your local council or Rent Smart Wales to start a formal inquiry.

Main Legal Duties for Landlords in Wales

Landlords in Wales must meet legal standards set out in the Renting Homes (Wales) Act 2016 and by Rent Smart Wales. Their core duties include:

  • Being registered and licensed with Rent Smart Wales before renting out property
  • Ensuring the property is safe and free from hazards (such as electrical/gas safety, fire safety, and damp/mould issues)
  • Completing repairs within reasonable timeframes
  • Not carrying out unlawful evictions or harassment

If a landlord fails to meet these responsibilities, they could face legal action, including prosecution by the council or other enforcement authorities.

If you think your landlord is breaching duties, keep records of all issues, communications, and repairs. Write to them requesting fixes and copies of any notices; enforcement actions typically require solid evidence. It can take weeks or months, so stay organized.

Key Situations Where Prosecution Can Happen

  • Unlicensed Letting: Landlords who rent out a property without proper registration and a licence from Rent Smart Wales may face prosecution and fines.
  • Ignoring Hazard Notices: If a local authority serves a formal improvement or hazard notice (for example, under the Housing Health and Safety Rating System) and the landlord ignores it, criminal prosecution can follow.
  • Harassment or Illegal Eviction: Deliberate harassment or unlawfully evicting a tenant can result in criminal proceedings against the landlord.

Each local council has a housing enforcement team responsible for investigating complaints and, where necessary, prosecuting offences.

Enforcement actions depend on evidence and can include penalties, civil orders, or prosecution; the process varies by council and may take time. Gather logs, emails, repair records, and witness statements to support your complaint.

How to Report a Landlord Who Breaks the Law

As a renter, you can report concerns using official complaint processes:

  • Report to Your Local Council: Your council’s housing enforcement team can investigate health and safety concerns, illegal evictions, and unlicensed letting. Find your council’s contact details using the official council finder.
  • Report to Rent Smart Wales: For licensing breaches or letting agent misconduct, submit a report directly to Rent Smart Wales.
  • Report a Serious Safety Issue: If there’s an immediate risk (like a gas leak), contact emergency services first, then notify your council.
When submitting reports, include dates, addresses, landlord or agent details, and copies of any notices or correspondence to build a clear case.

Relevant Official Forms and How Renters Use Them

  • Rent Smart Wales Complaint Form: To report an unlicensed landlord or agent, renters can use the online Rent Smart Wales Complaint Form.
    Example: If your landlord isn’t registered, fill out this form to request investigation and possible enforcement action.
  • Council Housing Complaint Forms: Many councils have online complaint forms for reporting repair or safety issues.
    Example: If your landlord ignores serious damp or refuses repairs, use your local council's website to report the problem for potential enforcement action.

Once a council or Rent Smart Wales receives your complaint, they will assess the situation. If they find legal breaches, they may serve formal notices or begin prosecution.

Example: If a council serves a formal improvement notice and your landlord continues to ignore it, document ongoing issues and consult Shelter Cymru or a legal adviser for next steps.

Which Tribunal Handles Housing Disputes in Wales?

While criminal prosecution is carried out in magistrates' courts, some tenancy disputes go to the Residential Property Tribunal Wales. This independent tribunal can decide cases such as rent disputes or fitness of your home for human habitation.

If you feel unsafe or your landlord is harassing or threatening you, contact your local council and seek advice from housing support charities as soon as possible.

What Legal Legislation Protects Renters in Wales?

The main legislation is the Renting Homes (Wales) Act 2016, which sets out landlords’ legal obligations, safety duties, and the rules for notices and evictions. Enforcement action and prosecution powers are defined within this Act and supporting regulations.[1]

The Act creates formal duties and enforcement tools; prosecutions typically require clear evidence that a duty was breached and that the breach was serious or persistent.

Summary

In short, landlords in Wales are legally required to register, provide safe homes, and treat tenants fairly. Serious breaches, such as unlicensed letting, persistent neglect, or harassment, can result in prosecution. Reporting problems via official forms or through your council is the first step to getting the support and enforcement you need as a renter.

Next steps: gather your tenancy agreement, notices, safety certificates, and a log of repairs; file a report with the council or Rent Smart Wales and follow up as needed.
