Rent Increase Challenges in Ireland

Refunds, Compensation & RTB Orders published July 05, 2025

Renting in Ireland comes with its own set of challenges, especially when it comes to facing rent increases. Understanding your rights and the legal framework governing these increases is vital for ensuring you are treated fairly. In Ireland, the Residential Tenancies Act 2004 (as amended) serves as the foundational document governing landlord and tenant relations.

Understanding Rent Increases

In the Republic of Ireland, rent increases must adhere to specific guidelines established by the Residential Tenancies Board (RTB). Rent reviews can only occur in line with the terms of your tenancy agreement, typically annually. Furthermore, any increase should align with the local market rents and cannot exceed these unless justified by a substantial increase in property value or improvements.

Legal Requirements for Rent Increase Notices

Your landlord must provide written notice of any rent increase. This notice must be given at least 90 days in advance and should clearly state the new rent and the date it takes effect. Failure to provide an adequate notice can render the increase invalid. For more detailed guidance, you can review the rent setting guidelines outlined by the RTB.

Challenging an Unfair Rent Increase

If you believe a rent increase does not comply with legal standards, you can dispute it. The first step involves discussing with your landlord. Should this fail, you can refer the matter to the RTB dispute resolution service. Ensure you gather evidence of comparable rents in your area to support your statement.

Always respond to rent increase notices promptly to avoid losing your right to dispute the change.

Relevant Forms and Procedures

  • Form 5: Available from the RTB, this form allows tenants to dispute rent reviews formally. It's crucial to submit this within the given timeframe following receipt of an increase notice.

Submission of a Form 5 involves filling out details about your tenancy, the disputed rent increase, and evidence supporting your case. Access on the RTB website.
