Understanding Rent Increases in Ireland

Tenant Rights & Responsibilities published July 05, 2025

Rent increases can be a source of stress for tenants in Ireland, but understanding the rules and your rights can help. Governed by the Residential Tenancies Act 2004 and its amendments, rent regulation aims to balance tenant security with landlord needs. In this guide, we unravel how these regulations affect you as a renter in Ireland.

Rules Governing Rent Increases

In Ireland, rent increases are primarily regulated under the Residential Tenancies Act 2004. According to this Act, landlords can only increase rent in accordance with set rules:

  • Notice Period: Tenants must receive a written notice at least 90 days before the increase takes effect.
  • Frequency: Rent can typically only be increased once in a 12-month period.
  • Capped Increases: In Rent Pressure Zones (RPZs), increases are capped at inflation or set limits by the Residential Tenancies Board (RTB).

For a detailed understanding of Rent Pressure Zones and their impact, you can refer to the RTB's official page on Rent Pressure Zones.

Your Rights as a Tenant

As a tenant, you have specific rights that protect you from unjust rent increases. If you receive a rent increase notice, ensure it:

  • Includes the date the new rent is to take effect
  • Lists the new rent amount
  • Includes the landlord’s contact details
  • Is delivered with adequate notice
If you suspect a rent increase notice does not comply with these requirements, you can dispute it with the RTB.

Forms You May Need

If you need to challenge a rent increase, complete the RTB Dispute Resolution Application Form. This form helps initiate a formal dispute process with the RTB. Tenants often use this when they believe rent increases are unfair or unjustified.
