How Rent Increases Work for Renters in Wales

Rent, Deposits & Increases Wales published: June 29, 2025 Flag of Wales

If you rent your home in Wales, you may wonder if your landlord can increase your rent without any warning. Understanding the rules around rent increases in Wales is essential to protect your rights, avoid unexpected financial shocks, and feel secure in your home.

Understanding Rent Increases in Wales

In Wales, private renters are usually under an 'occupation contract' as set out in the Renting Homes (Wales) Act 2016[1]. This law provides important protections on how and when your rent can be changed.

Does My Landlord Need to Give Notice?

No landlord can raise your rent in Wales without giving you proper written notice.

  • Periodic standard contracts: Your landlord must give you at least two months' written notice before a rent increase can take effect. This is usually done with a "notice of variation of rent" form.
  • Fixed term contracts: Your rent cannot be increased during the fixed term unless your contract has a specific clause that allows it and you agree.

The notice cannot be verbal—it must be made in writing using the correct legal form.

Official Notice Forms for Rent Increases

Your landlord should use the official RHW12: Notice of Variation of Rent form. This form is required by the Welsh Government and tells you:

  • The new proposed rent
  • When the rent increase will start
  • Your right to challenge the increase

View or download the RHW12: Notice of Variation of Rent form on the Welsh Government website.

If you receive a rent increase notice, keep a copy and check that it gives you at least two full months’ notice before the new rent begins.

Your Rights: Challenging an Unfair Rent Increase

You don't have to accept a rent increase if you believe it’s unfair or too high compared to similar local properties. You can challenge it with the Residential Property Tribunal Wales, the official tribunal handling rent disputes in Wales.

  • Within one month of receiving the RHW12 notice, you can apply to the tribunal.
  • The tribunal will look at market rents for similar properties in your area.
  • If the tribunal agrees, they can set a different rent, which the landlord must follow.

How to Respond If You Get a Rent Increase Notice

  • Check the notice: Make sure it’s the RHW12 form with the correct notice period.
  • Review your contract: For fixed-term renters, check if increases are allowed during the term.
  • Contact your landlord: If you think the increase is a mistake or want to negotiate, write to your landlord as soon as possible.
  • Apply to the tribunal: If you cannot agree, submit your challenge to the Residential Property Tribunal Wales within one month of being notified.
Keep all written communications and copies of forms as official records in case of dispute.

What Happens If the Proper Notice Isn't Given?

If your landlord tries to raise your rent without the official RHW12 notice or gives you less than the required two months' notice, the increase is not valid. You only need to pay the old rent amount until you receive proper notification.

In summary, your landlord in Wales cannot raise your rent without advance written notice using the right legal form. If you believe the increase is unfair, you have the right to challenge it through the tribunal process.
