How Often Your Landlord Can Raise Rent in Northern Ireland

If you’re renting a home in Northern Ireland, understanding how often your landlord can increase your rent is crucial for managing your finances and ensuring your rights are protected. The rules in Northern Ireland are specific and provide both landlords and tenants with clear guidelines. Below, we explain the key rules, your protections as a renter, and practical steps you can take if your rent is being increased.

How Often Can Rent Be Increased in Northern Ireland?

Most rented homes in Northern Ireland fall under an ‘assured tenancy’ or ‘statutory tenancy’ as regulated by the Private Tenancies (Northern Ireland) Order 2006[1]. Under recent reforms, the law limits how and when a landlord can raise the rent for existing tenants.

  • Frequency: Landlords may not raise the rent more than once in any 12-month period for the same tenancy.
  • Notice period: Your landlord must give you at least 3 months’ written notice before the proposed increase takes effect.
  • Notice format: The notice must be in writing and state the new rent and the date it will start.

This means you are protected from unexpected or frequent rent hikes, and you have a clear window to prepare or respond.

What Is the Legal Basis?

The rules on rent increases are set out in Article 7A of the Private Tenancies Act (Northern Ireland) 2022[2]. All new and existing tenancies must follow these updated procedures, including the notice requirements and annual restriction.

How Will You Be Notified?

Your landlord must use the official written notice to inform you of any rent increase. The recommended and most common form is:

  • Notice of proposed increase in rent (Form RT1) – This form should be completed by your landlord to propose a change in rent. It includes details of your tenancy, the proposed new amount, and when it would begin.
    Example: Your landlord fills in RT1 and gives it to you on the 1st of June, stating that your rent will rise starting from the 1st of September.

If you receive a rent increase notice that doesn’t follow these rules or isn’t on paper, you should question its validity.

Your Rights If You Disagree with a Rent Increase

If you feel that the proposed rent increase is excessive, you do not have to accept it immediately. The law allows you to challenge it.

  • Contact your landlord first: Open a discussion to explain your concerns.
  • Apply to the Rent Assessment Committee (Northern Ireland): If you cannot agree, you may apply to the official tribunal for a formal review.

The Rent Assessment Committee (Northern Ireland) is the official body that considers rent increase disputes, independently reviewing whether the proposed rent is fair.

You must apply to the Rent Assessment Committee within 28 days of receiving the rent increase notice if you wish to challenge it officially.

How to Challenge a Rent Increase

  • Check the notice for correct details and dates
  • Respond to your landlord in writing if you disagree
  • Complete and send the Application to Rent Assessment Committee form (available from your local District Council Housing Office or the Rent Officer – see official guidance on challenging a rent increase)
  • Attend the committee hearing if required

The Committee will look at rents for similar properties in your area and decide what is fair. Their decision is binding for both you and your landlord.

Summary of Key Steps for Renters

  • Landlords can only raise rent once per year
  • Written notice (usually Form RT1) must be given 3 months in advance
  • You have a right to challenge a proposed rent increase with the Rent Assessment Committee

The process is designed to ensure transparency and fairness for both parties.
