Rent increases in private rented housing


The amount of rent payable for a property is agreed between the landlord and tenant at the start of a tenancy. Private landlords must follow certain procedures if they want to raise the rent. The rules are set out in Part 3 of the Residential Tenancies Act 2004 and have been amended by the Residential Tenancies (Amendment) Act 2015 and the Planning and Development (Housing) and Residential Tenancies Act 2016.

These rules only apply to private rented housing, not to housing that is let by local authorities or approved housing bodies (housing associations), both of which charge differential rents based on household income. While approved housing bodies now come under the residential tenancies legislation, their rent reviews will continue to be carried out in accordance with their tenancy agreements, or no more than once in any 12-month period.

Rent Predictability Measure

The Strategy for the Rental Sector proposed a Rent Predictability Measure, to cap rent increases at 4% per year for the next 3 years in designated Rent Pressure Zones. The Planning and Development (Housing) and Residential Tenancies Act 2016 brought this measure into effect from 24 December 2016. It was implemented immediately in the 4 Dublin local authority areas and in Cork city.

Rent Pressure Zones are designated for a maximum of 3 years.

There is more about this and other measures on, including a set of FAQs (pdf).

Residential Tenancies Board

The Residential Tenancies Board (RTB) has a central role in supporting the rented housing market. It deals with disputes between landlords and tenants, including disputes about rent reviews. It also provides information about rent reviews and increases.

Market rent

Under Section 19 of the Residential Tenancies Act 2004, landlords cannot charge more than the open market rate of rent. Market rent (for properties outside Rent Pressure Zones) is defined in Section 24 as ‘the rent which a willing tenant not already in occupation would give and a willing landlord would take for the dwelling’. The RTB publishes a quarterly index of rents, which you can use to check current market rents. Read more about market rent and the rent index.

Rent reviews

A rent review can result in an increase or reduction of the rent. In general, your landlord has the right to review the rent once every 2 years. Unless the accommodation has changed substantially, it cannot be reviewed more often than this, unless it is in a Rent Pressure Zone.

Rent Pressure Zones: Under the Rent Predictability Measure, a number of Rent Pressure Zones have been designated. Rent increases in these zones are capped and there are limits on how often the rent can be reviewed. There is a full list of Rent Pressure Zones on

For a new tenancy (starting on or after 24 December 2016) in a Rent Pressure Zone, the landlord may review the rent once every 12 months. The maximum rent increase will be 4% per year. The landlord must give the tenant the following information, in writing, at the start of the tenancy:

  • The amount of rent that was last set under a tenancy for the dwelling
  • The date the rent was last set under a tenancy for the dwelling
  • 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

In existing tenancies (starting before 24 December 2016) the first rent review in a Rent Pressure Zone may take place a minimum of 24 months from either the start of the tenancy or from the date when you were notified in writing of your last review. The maximum rent increase is 2% per year since the previous rent was set. So, if the rent is reviewed when the minimum 24-month period has elapsed, the maximum rent increase is 4%. If more time has passed since the previous rent was set, the maximum rent increase is higher. Subsequent rent reviews may take place after a minimum period of 12 months.

The following table gives examples of allowable rates of increase for existing tenancies (starting before 24 December 2016) in Rent Pressure Zones after different periods.

Examples of allowable rates of increase after different periods since previous rent was set
Date rent was last set Date new rent is being set Time between setting old rent and setting new rent Allowable rent increase
5 December 2013 5 December 2017 48 months/4 years 8% (2% per year for 4 years)
5 December 2014 5 December 2017 36 months/3 years 6% (2% per year for 3 years)
5 December 2015 5 December 2017 24 months/2 years 4% (2% per year for 2 years)
5 December 2016 5 December 2017 12 months/1 year No rent increase allowed until 2 years have passed

Exceptions: Properties that have not been let at any time in the previous 2 years, or that have been substantially changed, can be exempted from these caps. However, the rent set for a property must be in line with market rent for similar properties in the area.

The RTB has published detailed guidelines for landlords and tenants (pdf), explaining what counts as "substantial change” to a rented property to allow a landlord to exceed the cap on rent increases in a Rent Pressure Zone. Read more in this reference leaflet (pdf).

Outside of Rent Pressure Zones: Your rent cannot be reviewed until 24 months after the start of your tenancy. If your rent was reviewed at any time in the last 24 months, it cannot be reviewed again until 24 months after the date of the last review.

Calculating allowable rent increases

You can use the RTB’s calculator to check whether your dwelling is in a Rent Pressure Zone and to work out whether the rent can be raised and, if so, by how much. You will need to enter your address or Eircode, the current rent and the date when the rent was last set.

The RTB has published examples (pdf) of how the calculations work.

Notice of rent review

Once the required period (12 or 24 months) has elapsed, your landlord can issue a notice of rent review.

The landlord must give you proper notice of the amount of the proposed new rent and the date from which it is to take effect. The notice must be in writing and contain the information prescribed by the legislation – see ‘Notice of rent review’ below. Emails, text messages and spoken messages are not valid forms of notice.

You must get at least 90 days’ notice of a rent review. This means that the new rent cannot then apply until 90 days after the notice has been issued.

The landlord must also notify the RTB of the revised rent so that it can update the registration details of the tenancy.

The notice of new rent must comply with the provisions of Section 26 of the Residential Tenancies (Amendment) Act 2015. The notice must:

  • State the amount of new rent and the date from which is to have effect
  • Include a statement that any dispute about the setting of the rent must be referred to the RTB before the date the new rent takes effect, or within 28 days from the date that the tenant gets the notice, whichever is the later
  • Include a statement by the landlord that, in their opinion, the new rent is not greater than the market rent, having regard to the other terms of the tenancy and to letting values of dwellings of a similar size, type and character and situated in a comparable area
  • Specify the rent amount being asked for 3 dwellings of a similar size, type and character and in a comparable area, which have been advertised for rent in the 4-week period immediately before the notice
  • Be signed by the landlord or their authorised agent and include the date on which it was signed

In a Rent Pressure Zone, the notice must also comply with Section 35 of the Planning and Development (Housing) and Residential Tenancies Act 2016.

  • In a Rent Pressure Zone, the landlord must also provide information and calculations to demonstrate that the rent increase is not more than 4% per year for the period since the rent was last set.

The RTB has published a sample notice of rent review, which includes the extra information required in Rent Pressure Zones.

Requesting a rent review

As a tenant, you can ask your landlord to review the rent if:

  • You think it is more than the current market rate for the property or
  • You want a new review and more than 24 months have passed

If your landlord is raising the rent

Threshold, the national housing charity, publishes detailed advice on how to deal with rent increases. Its leaflet on resolving problems during your tenancy (pdf) includes tips on dealing with rent increases. You can contact Threshold for advice on your particular situation – see ‘Where to apply’ below’.

If there is any dispute about the amount of rent being proposed, either side can refer the dispute to the RTB. If you are claiming that the proposed rent is higher than the market rate, you should provide evidence of rental rates for similar properties in the same area.

If the landlord has given you a valid written notice of the rent increase, you must contact the RTB with your dispute before the date that the new rent comes into effect or within 28 days of getting the notice, whichever is later. There is no time limit if the notice is not valid.

You must continue to pay your rent until the case has been determined by the RTB.

Protecting your tenancy

You can contact Threshold’s Tenancy Protection Service on 1800 454 454 for general support, advice and advocacy around protecting your tenancy.

If you are getting (or applying for) Rent Supplement, there may be flexibility in cases where landlords seek rents that are above the Rent Supplement limits. This applies to existing tenants and to new Rent Supplement applicants. The circumstances of tenants are considered on a case-by-case basis and rents increased above the set limits as appropriate. Contact the local office that administers your Rent Supplement. The Tenancy Protection Service can help you in making an application.

The Department of Employment Affairs and Social Protection, in conjunction with Threshold, operates a special protocol for tenants on Rent Supplement in areas where supply issues are particularly acute - Dublin, Kildare, Meath, Wicklow, Cork city and environs, Galway, Mayo and Roscommon. Contact the Tenancy Protection Service on 1800 454 454.


To refer a dispute to the RTB for resolution, it costs €15 to apply online and €25 for an application on paper (contact the RTB to request a form).
