Understanding Rent Increase Regulations in Ireland

Tenancy Types & Agreements published July 05, 2025

For many tenants in Ireland, managing rental costs is a crucial aspect of living arrangements. Understanding the rules surrounding rent increases, as governed by the Residential Tenancies Act 2004 (as amended), is essential. These rules ensure that landlords follow legal procedures, providing tenants with the necessary protection.

Regulations on Rent Increases

In Ireland, landlords can only increase rent once every 12 months and must provide a minimum of 90 days' written notice before the increase takes effect. This written notice must be clear, outlining the new rent amount and the date it will commence.

How to Challenge a Rent Increase

If you believe a proposed rent increase is unjustified, you have the right to challenge it. Follow these steps to ensure your challenge is heard:

  1. Review the Notice: Check that the notice meets all legal requirements under the Residential Tenancies Act 2004 and the increase aligns with market rents for similar properties.
  2. Respond in Writing: File a written objection with your landlord within the notice period, stating your reasons.
  3. Contact the RTB: If your objection remains unresolved, apply to the Residential Tenancies Board (RTB) for assistance. They offer dispute resolution services to help you and your landlord come to an agreement.

Required Forms

To file a dispute regarding a rent increase, tenants need to complete Form DR1 - Notice of Dispute. This form can be downloaded from the RTB website and should detail the nature of the dispute, evidence supporting your claim, and any previous correspondence with your landlord.

Compliance with Housing Standards

Rent increases must coincide with proper maintenance of rented properties. The Housing (Standards for Rented Houses) Regulations 2019 set minimum standards for rental accommodation, helping to ensure safe and comfortable living conditions. Any increase should reflect compliance with these standards.

Tip: Always keep detailed records of rental payments and communications with your landlord regarding any changes to your tenancy agreement.

Turn to the RTB for Appeals

If a consensual agreement cannot be reached, the Residential Tenancies Board is your go-to for lodging an official dispute. Engage their dispute resolution services to mediate or adjudicate the matter.

FAQs
