How to deal with rent increases

What you can do if your landlord wants to increase your rent

Rent Pressure Zones (RPZ)

From 24th December 2016  specific areas have been designated as rent pressure zones or RPZs and these have been extended to 31st December 2024. You can find out if you are renting in a designated RPZ by clicking here

If you are renting in a rent pressure zone, the rules as to how your rent can be reviewed have changed. From 11th December 2021,the setting of the initial rent and any rent review, is calculated according to what is called the Harmonised Index of the Consumer Price (HICP) or capped at 2%, whichever is the lower. To work out the amount your rent can be increased by you can check the RTB calculator by clicking here.

The  RPZ rules apply if you are moving into tenancy which is located within a rent pressure zone. In this case, upon commencement of the tenancy,  the landlord is required to give you written information outlining the amount of rent and date it was last set under a tenancy for the dwelling and a statement as to how the rent set under the tenancy of the dwelling has been calculated having regard to the rent pressure zone formula. If you don't get this the landlord is in breach and you can report this to the Investigation and Sanctions Unit of the RTB by clicking here.

 Opposite you will find a letter Tenant Rent Info which you can download and use to inform a new tenant that moves into the property you were previously renting of the amount of rent you were paying when you left.



Where a property has been let for the first time or hasn't been rented out in the previous two years the RPZ rules will not apply for the initial setting of the rent but will for all subsequent reviews. Also the RPZ rules will not apply where there has been a substantial change in the nature of the accommodation. This has been given a statutory definition to include:

Either a permanent extension increasing the floor area by 25% or 

An increase in the BER rating by 7 or at least three of the following:

  • a permanent change in the layout
  • adaption for person with a disability
  • permanent increase in the number of rooms
  • increase of BER rating  of 3 or more for ratings D1 or lower or increase of BER rating of 2 or more for ratings C3 or higher

A landlord seeking to rely upon this exemption must inform the RTB in writing of this along with any suppporting documentation within one month of the setting of the new rent.


It is important to know that bringing a property up to minimium standards does not qualify for an exemption.


Renting Outside of a Rent Pressure Zone

If you are renting outside a RPZ the rules have also been extended until 31st December 2024. Whilst there is no percentage increase on how much your rent can be increased by like in a RPZ, your landlord cannot charge more than 'market rent' when seeking a rent review and it must be at least 24 months from the date of your last review-this is the notification that you received of a rent review and not the date you started paying the new rent. Following the expiry of the 24-month period your landlord/agent must give at least 90 days written notice of the amount of the new rent and date it is to take effect from. The notice must be in writing, email, text or verbal notice are not valid and it cannot be given before the expiry of the 24-month period.

To determine 'market rent' you can check a number of sources including the Residential Tenancies Board (RTB) Rent Index, property websites, property agents, to let ads in newspapers etc. Threshold advises that you try to negotiate with your landlord around the increase and you can download the top tips for doing this opposite.  You must be given at least three comparable rents of similar properties in your area which have been advertised in the previous four weeks to your review.

Rent reviews for both inside and outside of RPZs must be in writing, and follow a prescribed form set out in law, which should not be varied from as it could make the notice invalid. You can download the RTB rent review form on this page.

If you wish to dispute a review you can refer a case to the RTB within 90 days' of receipt of the notice or before the date when the review is to take effect, whichever is later. If you wish to challenge a valid notice of rent review you should continue paying the current rent until the RTB issue a Determination Order. It is important to note that the RTB may accept the proposed review and the increase may be backdated.

If you decide not to challenge the increase and give notice to leave it is important to note that you will be liable to pay the new rent from its commencement date and if you fail to do so the landlord may seek to make deductions from, or retain your deposit to cover the lost rent.

If you are in receipt of rent supplement and facing a rent increase, the Tenancy Protection Service may be able to help you apply for an enhanced payment, click here for more information.
