Joint Tenancy Rent Rules and Rights in Wales

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

Renting a home with others in Wales comes with unique rules and responsibilities. If you are in a joint tenancy, understanding how rent rules apply can help you avoid disputes, manage rent increases, and know your legal rights. Whether you share with friends or family, knowing your position under current Welsh law empowers you to protect your home and budget.

What is a Joint Tenancy in Wales?

A joint tenancy is where two or more people share equal responsibility for a rental agreement. In Wales, since December 2022, most renters have ‘occupation contracts’ under the Renting Homes (Wales) Act 2016. This means you and your housemates are all ‘contract-holders’, each with equal rights and obligations under the agreement.

  • All contract-holders are jointly and individually responsible for paying the total rent.
  • If one person leaves without ending the contract, remaining people are still responsible for the whole rent.
  • All names should appear on the written occupation contract provided by your landlord.

How Are Rent Payments Managed?

For joint tenancies or occupation contracts, the group typically pays rent as a single payment. If one person cannot pay, everyone else may legally be required to cover the shortfall. This is called ‘joint and several liability’.

  • Rent can be split however you agree among yourselves, but you’re all liable for the full amount if there is a problem.
  • If a contract-holder leaves, you must tell the landlord—adjusting responsibility may require ending and creating a new contract.
  • Written confirmation of rent received is required by law if paying in cash.

Rent Increases in Joint Tenancies

Landlords in Wales can only increase rent by following rules set out in the Renting Homes (Wales) Act 2016.

  • Rent increases are allowed only once every 12 months for standard occupation contracts.
  • Your landlord must give at least two months’ written notice using the Notice of Proposed Rent Increase (RHW5) form.
  • Every contract-holder must be notified individually.

The Official Form: Notice of Proposed Rent Increase (RHW5)

When used: If your landlord wants to increase the rent under an occupation contract, they must serve you the official Notice of Proposed Rent Increase (RHW5) form. This notice must outline the new rent and the date it will take effect, giving you at least two months’ warning.

Example: Sarah and three friends share a flat. If the landlord wishes to increase rent from £900 to £950, each contract-holder gets their own RHW5 form, and the increase can’t start sooner than two months from the date of the notice.

What if You Disagree with a Rent Increase?

If you think a rent rise is unfair or has not followed legal procedure, you have the right to challenge it:

  • You must apply to the Residential Property Tribunal Wales within two months of receiving the notice.
  • The tribunal will review if the increase is above market value or not in line with the law.
  • Your rent cannot be put up until the tribunal’s decision.
If you plan to challenge a proposed rent increase, always keep written records and respond before the deadline.

When One Joint Contract-Holder Leaves

If one person wants to move out, the process depends on your contract and your landlord’s agreement:

  • With the landlord’s consent, you can replace a contract-holder using a process called ‘transfer’ or ‘substitution’.
  • You may need to update your written contract using the Notice of Variation for an Occupation Contract form.
  • If the landlord does not agree, the remaining contract-holders may have to end the contract and start a new one.

This helps clarify everyone’s rights and responsibilities in case a housemate moves out.

Your Rights Under Welsh Housing Legislation

Your joint occupation contract (formerly called joint tenancy) is regulated primarily by the Renting Homes (Wales) Act 2016. This law sets out:

  • The way contracts must be written and provided
  • The notice periods for rent increases
  • Your right to challenge unfair rent or landlord actions
Always make sure you have a written copy of your occupation contract and keep any forms your landlord gives you.
