How to Negotiate Rent Successfully with Your Landlord in Wales

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

If you're renting in Wales and facing a rent increase or want to negotiate your rent, it's important to know your rights. Understanding the rules set by Welsh law and using the right steps can help you come to a fair agreement with your landlord — and protect your home. This guide explains the process of negotiating rent in Wales, including official forms, how to respond to rent increases, and your legal protections.

Understanding Your Tenancy and Rent Rules in Wales

Most private renters in Wales have a contract called an 'occupation contract', since changes brought in by the Renting Homes (Wales) Act 2016[1]. This law sets out your rights, including how rent increases must be handled and how you can negotiate safely.

  • You have the right to receive notice in writing if your landlord wants to increase the rent.
  • Rents can be increased only once every 12 months for most occupation contracts.
  • Any rent increase notice must use the official form 'Landlord’s Notice of a Rent Increase (RHW12)'.

Always check what type of tenancy or occupation contract you have before starting negotiations, as your rights may differ slightly.

How Do Rent Increases Work in Wales?

Your landlord cannot simply informally demand a higher rent — they must follow official process and provide notice. The official process is as follows:

  • The landlord must give at least two months’ notice in writing using the RHW12 Rent Increase Notice.
  • The notice must state the new rent amount and the date the increased rent starts.
  • This can only be done once every 12 months for standard occupation contracts.

If you believe the increase is too high or unfair, you have options to challenge or negotiate.

Negotiating Rent: Your Options and Rights

Negotiating doesn’t always mean saying no. You can try to agree a more affordable rent or discuss improvements to balance a rise. Here's how to approach it:

1. Talk to Your Landlord

  • Explain your situation clearly and calmly.
  • Show evidence if needed (like comparable rents locally, financial hardship, or maintenance problems).
  • Be ready to compromise, for example by agreeing to a smaller increase or longer tenancy.
Keep all communication in writing for your records, and avoid making verbal agreements only.

2. Use the Official RHW12 Form: When and How?

Landlords in Wales must use the Landlord’s Notice of a Rent Increase (RHW12) to propose higher rent for standard contracts.

  • Landlord’s Notice of a Rent Increase (RHW12): Used to officially notify you of an intended rent increase.
    For example: If your landlord wants the rent to rise from £700 to £750 per month, they must provide this completed notice at least two months before the change.

If you do not agree with the increase, Welsh law allows you to challenge it.

How to Challenge a Rent Increase in Wales

If you believe your new rent is above the market value, or you simply can't afford it, you may refer the matter to the official tribunal:

  • The Residential Property Tribunal Wales is the official board for rent disputes between landlords and tenants in Wales.
  • You must apply to the tribunal before the date the new rent is due to take effect (within two months of receiving the RHW12 notice).

To apply, use the following process:

In most cases, it's best to try negotiation directly with your landlord before involving the tribunal, but the tribunal provides a neutral, legal decision if needed.

Tips for Successful Rent Negotiations

  • Check the average rent for similar properties in your area using trusted data sources or local council websites.
  • Consider offering something in return (such as a longer-term commitment).
  • Be clear, polite, and firm about your needs and your limits.
  • Keep copies of all correspondence and notices.

Remember: agreeing rent changes in writing protects both you and your landlord.
