Before you start: can you review at all?
- At least 12 months since the tenancy began or the last rent review notice was served (the RTB counts from the date the rent was set, not from the day the new rent started). 24 months if the tenancy began before the area became a Rent Pressure Zone and the last rent was set before that date.
- The tenancy is registered and up to date. Check it.
- You have a current BER certificate: the form asks for the rating and the floor area from it.
Part A: tenancy details
Tenancy type (private or student accommodation), address on five lines, Eircode, the RT number of the tenancy, start date, floor area in square metres, BER, and whether the home is in a new or extended apartment development started after 10 June 2025 (those follow inflation only).
The floor area is the one recorded on the BER assessment. We take it from the SEAI register for your Eircode.
Part B: the new rent
Current rent and frequency, the date the last notice was served (or the tenancy start), the new rent and frequency, the date it takes effect (at least 90 days after service), and the date you sign and serve. Then three boxes: which rule applied (2% or inflation; inflation only; exemption), whether the RTB calculator printout is attached, and whether Part D is filled in.
The limit is the lower of CPI inflation since the rent was last set and 2% a year pro rata. Calculator.
Part C: three comparable dwellings
Section 19 is the landlord’s statement that the new rent is not above market rent, backed by three registered tenancies from the RTB Rent Register: RT number and rent for each. The criteria are written into the form: similar floor area, bedrooms, BER, and a comparable area. Our register search sorts by exactly those.
Part D: exemptions
Only if you claim an exemption from the cap: an extension of 25% or more of floor area, a BER improvement of at least 150 kWh/m²/year, three or more of five listed works, the end of a six-year tenancy cycle, or student accommodation after three years. Each needs documents. Most reviews leave Part D blank and tick “not applicable” in section 18.
Part E: documents attached
List them: calculator printout, comparables sheet, BER certificate, and anything for Part D.
Part F: who serves it
Landlord or authorised agent, names, postal address, Eircode, the declaration, name in block capitals, signature.
