As a renter in Wales, understanding how often your rent can be increased and what steps to take if you receive a rent increase notice is essential. Welsh housing law sets out specific rules for rent rises, notice periods, and your rights to challenge unfair increases. This guide explains the process, official forms involved, and what to do if you think a rent increase is unreasonable.
How Often Can Rent Be Increased in Wales?
In Wales, under the Renting Homes (Wales) Act 2016, most private renters now have an "occupation contract". This modernises and replaces older tenancy types. Landlords must follow strict rules about when and how rent can be increased.
Key points about rent increases:
- Rent can usually only be increased once every 12 months for standard occupation contracts.
- Your landlord must give you at least two months’ written notice before the new rent starts.
- The correct notice must be given using the official form (RHW12 – see details below).
- Rent cannot be increased during a fixed term unless your contract explicitly allows it, or unless you agree in writing.
These rules protect renters from sudden or frequent rent hikes, and ensure you have time to plan and respond.
What Notice Must Landlords Give?
Your landlord must use the official Welsh Government notice form called RHW12: Notice of a Proposed Increase in Rent. This form must be given to you in writing at least two months before the date the increased rent would apply. The notice should clearly state:
- The current rent
- The proposed new rent
- The date the new rent will begin
- Your rights to challenge the increase
You can view and download the RHW12: Notice of a Proposed Increase in Rent directly from the Welsh Government website. For instance: if your landlord gives you the RHW12 form on 1 June, the new rent must not start until at least 1 August.
When Is a Rent Increase Not Allowed?
- If you are still within a fixed term of your occupation contract and there is no clause allowing for rent increases
- More than one increase within a 12-month period
- If the landlord fails to provide the correct notice using RHW12
If an increase does not comply with the above, you do not have to pay the new rent, and you should inform your landlord in writing.
How to Challenge an Unfair Rent Increase
If you believe your rent increase is excessive or unfair, you have a legal right to challenge it through the tribunal. In Wales, this is handled by the Residential Property Tribunal Wales.
- You can apply using the application forms on the tribunal's website.
- The tribunal will review whether the proposed rent reflects the market rate for similar properties in your area.
- If successful, the tribunal may set a different rent, which is legally binding for both parties.
Always keep copies of all correspondence and notices when disputing a rent increase.
Summary of steps to challenge a rent increase:
- Check if you received the correct RHW12 form with at least two months' notice
- Respond to your landlord in writing if you disagree
- Apply to the Residential Property Tribunal Wales before the increase takes effect
