Rent Increase Rules and Your Rights as a Renter in Wales

If you’re renting a home in Wales, it’s important to know your protections and rights when your landlord wants to raise your rent. Recent changes in Welsh tenancy law mean your rights can differ from other parts of the UK. Understanding rent increase rules can help you spot when a rent hike is unfair – and how to take action if needed.

Understanding How Rent Increases Work in Wales

Rent increases for tenants in Wales are governed by the Renting Homes (Wales) Act 2016.¹ The law sets out clear rules on when and how your landlord can put the rent up, depending on the type of agreement you have.

Periodic Standard Occupational Contracts

• Rent can usually only be increased once a year.
• Your landlord must give you a written notice period of at least two months before any increase starts.
• They must use the correct official form to notify you about the rent increase (see below).

This means you should always have advance warning—and no sudden monthly rent jumps.

Fixed Term Standard Occupational Contracts

• Your landlord can only increase your rent during a fixed term if your contract specifically allows it.
• If your contract doesn’t mention rent increases, your rent can only change at the end of the fixed term or if you agree in writing.

How Must Landlords Notify You of a Rent Increase?

To raise your rent legally, your landlord must give you at least two months’ written notice using an official form:

• Notice of variation of rent (RHW12 form): This is the official form landlords must use to notify you of a rent increase for a periodic standard contract. It is available from Welsh Government – RHW12 Notice to vary rent.²

Practical Example: If your landlord wants to increase your rent in June, they must give you the RHW12 notice by at least April, using the correct form and information. If you receive a different letter or an email, that's not legally valid—the process must follow this formal route.

What If You Think the Rent Increase Is Unfair?

If you believe the new rent is significantly above market value, you have the right to challenge it. The tribunal responsible for rent disputes in Wales is the Residential Property Tribunal Wales (RPT).³

How to Challenge a Rent Increase

• Object in writing to your landlord if you think the increase is too high.
• If you can’t reach an agreement, you can apply to the Residential Property Tribunal Wales within the specified timeframe (usually before the new rent is due to take effect).
• Prepare evidence (like adverts for similar properties) to support your case.

Submitting a challenge does not mean the rent will definitely be lowered—but the tribunal can assess whether the proposed rent is fair compared to similar homes in your area.

Key Things to Remember About Rent Increases in Wales

• You must get at least two months’ official notice of any rent increase (periodic contracts).
• Your landlord can’t increase your rent more than once a year if you have a periodic contract.
• You can challenge unfair increases at the Residential Property Tribunal Wales.

You cannot be evicted simply for challenging a rent increase, as long as you pay the existing legal rent while a dispute is ongoing.
