Landlord Changed Locks in Wales: Your Tenant Rights Explained

Eviction Notices & Repossessions Wales 4 min read · published March 09, 2026 Flag of Wales

If you discover your landlord has changed the locks on your rental home in Wales without warning, it can feel distressing and unfair. Many renters wonder what their rights are and what steps they can take to regain access. In Wales, strict rules protect tenants, and landlords must follow a formal legal process when ending a tenancy. This article covers what you should do if your landlord changes the locks, your rights under current Welsh legislation, and the official actions available to you.

In Wales, unlawful eviction is a criminal offence. Tenants may seek help from councils, housing advisers, or legal services, and must follow the formal eviction process for any eviction to be lawful.

Is It Legal for a Landlord to Change the Locks in Wales?

Under Welsh law, landlords cannot just change the locks or exclude you from your property without following a specific legal process for eviction. This type of action is commonly known as 'unlawful eviction'.

  • A landlord must serve you with a proper eviction notice, giving the correct amount of notice depending on the tenancy type.
  • Only after a court order or warrant for possession has been obtained, can a landlord take steps to repossess the property.
  • It is illegal for a landlord to change the locks, threaten, or physically remove tenants without a court order.

Unlawful eviction is a criminal offence in Wales, and tenants have the right to seek help from the authorities.

Immediate Actions If You Are Locked Out

Discovering a changed lock can be alarming, but staying calm and acting quickly can protect your rights:

  • Do not try to force your way back in, as this could lead to legal trouble.
  • Gather evidence such as photographs or videos of the new locks, and keep a record of missed belongings inside.
  • Contact your landlord and request immediate re-entry. Keep all communications in writing if possible.
  • If you cannot regain access, call your local council's housing department, as they can intervene.
  • You may contact the police using the non-emergency number (101) to report unlawful eviction.

If you are at risk of homelessness or need urgent help after lockout, contact your local council's homelessness service immediately.

The Formal Eviction Process in Wales

Landlords in Wales must serve a valid notice before eviction. Here are the steps:

  • For most tenancies, your landlord should serve a written statement of contract and then issue a Termination Notice if they want you to leave.
  • After the notice period, if you do not move out, the landlord must apply to court for a possession order via the Possession Claim Online system.
  • Only after a court grants a possession order, and a bailiff attends, can the landlord lawfully remove you or change the locks.

Relevant Forms to Know

  • Notice Seeking Possession (Section 173 Notice)
    If you rent via an occupation contract (introduced under the Renting Homes (Wales) Act 2016), your landlord should serve a Section 173 Notice. This must provide at least six months’ notice in most cases, unless for antisocial behaviour.
    See official model notices here.
    Example use: Your landlord completes this notice, serves it to you, and if you remain, then applies for a court possession order.
  • Possession Claim Form N5B Wales
    This is used by landlords to apply to the county court for a possession order. See Form N5B Wales.
    Example use: After notice expires, landlord applies to court. The court sends you a copy and allows you to submit a defence.
  • Defence Form N11B Wales
    If you receive Form N5B, you may respond with Defendant’s Defence (N11B Wales). See Form N11B Wales.
    Example use: Use this to explain why you believe you should not be evicted (e.g. incorrect notice given).

Reporting Unlawful Eviction

If a landlord changes the locks without following the formal process, you can report them to your local council’s environmental health or housing department.
The local authority can investigate and may prosecute the landlord under the relevant legislation.

You can also seek advice or take civil action for re-entry or compensation.

If you report the eviction, keep copies of any correspondence and await council investigation; do not delay seeking shelter or legal advice as investigations can take time.

Who Handles Tenancy Disputes in Wales?

Disputes about unlawful eviction or possession claims in Wales are handled by the County Court. In Wales, housing law and eviction rules are based on the Renting Homes (Wales) Act 20161.
