Myth vs reality · Ireland · checked 25 October 2026
In Ireland in 2026, your landlord can raise the rent once every 12 months by 2% or the rate of inflation, whichever is lower. With the CSO's consumer price index at 4.1% in September 2026, 2% is the ceiling for most tenants: on the average existing-tenancy rent of €1,513, that is €30.26 a month, tops. Yet half of what renters repeat to each other about the new rules is wrong. We checked nine of the most common beliefs against the law and the latest official data.

minimum notice your landlord must give before a new rent takes effect
Ireland's rental rules changed twice in nine months. On 20 June 2025, Rent Pressure Zone rules were extended to every private tenancy in the country. Then, on 1 March 2026, a new national system took over, with six-year tenancies, limits on no-fault evictions and new rules on when rent can be reset to market level. The Residential Tenancies Board's summary of the March 2026 changes is the clearest official guide, but it is written for both landlords and tenants and it does not tell you which of the things you've heard are simply not true. That's what this page is for.
How to read the verdicts: TRUE the belief holds up. FALSE the law or the data says otherwise. IT DEPENDS the answer turns on when your tenancy started or who your landlord is.
Rent increase rules in Ireland 2026: the 9 myths, checked
FALSE
Myth 1: "My landlord can put the rent up in line with inflation."
Reality: The annual increase is capped at 2% or inflation, whichever is lower. Inflation is not the ceiling when it is running hot; 2% is. The CSO reported consumer prices up 4.1% in the 12 months to September 2026, with energy products up 15.3% and private rents in the index up 4.7%. None of that gives your landlord permission to pass 4.1% on to you.
The one exception: new private apartments where construction began after 10 June 2025 can rise in line with CPI with no 2% limit, according to the RTB's rent review guide. If you rent a brand-new apartment, ask your landlord directly whether that exemption applies, and check the notice for it.
FALSE
Myth 2: "Rent Pressure Zones only protect people in Dublin and the cities."
Reality: That was true for years, and it is still what many people remember. Since 20 June 2025, every private and student-specific tenancy has been under the same cap. The RTB said the 2025 extension alone brought 17% of private tenancies, across 59 local authority areas, under the rules for the first time. From 1 March 2026, the RTB describes RPZs as replaced by a national rent control system. Renting in Leitrim, Laois or Kerry gets you the same 2% ceiling as renting in Rathmines.
IT DEPENDS
Myth 3: "The new March 2026 rules now apply to my lease."
Reality: It depends on the date your tenancy was created. The new security-of-tenure rules apply to tenancies created on or after 1 March 2026. If your tenancy started before then, the older termination rules still apply: the landlord can end it after the first six months for one of six reasons (your breach, the home no longer suits you, landlord or family moving in, sale, substantial refurbishment, or change of use), whatever the size of the landlord.
There's a hidden upside for older tenancies, though. For private tenancies created before 1 March 2026, a reset to market rent is not allowed. Your rent can only move by the annual cap. If you've been in the same home for years, your rent may be well below today's asking prices, and that gap is protected.
FALSE
Myth 4: "Whenever a tenancy ends, the landlord can reset the rent to whatever the market pays."
Reality: For private tenancies created from 1 March 2026, a market reset is allowed in two situations: at the start of a new tenancy, but only if the previous tenant left voluntarily, breached their obligations or the home no longer suited them; and at the end of a six-year cycle. A landlord who ends a tenancy on a no-fault ground, such as a sale or a family member moving in, cannot reset to market rent for the next tenancy.
Even when a reset is allowed, it has to be justified. The landlord must state that the new rent is not above market rate and give details of three comparable properties from the RTB Rent Register. If you think the rent is above market, you can bring a dispute; the RTB says adjudication or a tribunal can order overpaid rent to be repaid and award damages of up to €20,000.
IT DEPENDS
Myth 5: "Once I've been there six months, I can't be asked to leave."
Reality: Six months is the turning point, but it isn't a force field. After six continuous months without a valid notice of termination, you gain security of tenure, and the landlord can only end the tenancy for specific legal reasons. Which reasons depends on the landlord:
- Landlords with four or more tenancies, or company landlords (tenancies from 1 March 2026): only your breach of obligations, or the home no longer suiting your needs.
- Landlords with one to three tenancies (tenancies from 1 March 2026): those two reasons, plus a sale needed to avoid undue hardship or the landlord or a close family member needing to live there during the six-year term, and a wider list at the end of the cycle.
Worth knowing: in the first six months, a landlord can end a tenancy for any reason. Don't treat month five as "safe".
FALSE
Myth 6: "A text or an email is enough to put the rent up."
Reality: A valid increase needs the RTB's Notice of Rent Review form, served at least 90 days before the new rent takes effect, with a printout from the RTB Rent Calculator and details of three comparable properties from the Rent Register. A copy must go to the RTB too. The RTB states that notices must go to the tenant and the RTB on the same day, and that a notice not sent to the RTB is invalid. The landlord also has to update the tenancy registration within a month of the change.
If you've had a "heads up, rent's going up next month" message, that is not a valid rent review. Reply politely and ask for the formal notice.
FALSE
Myth 7: "The new controls have made rents cheaper for people moving now."
Reality: So far, the data points the other way for people starting a new tenancy. The RTB's index for January to March 2026, reported by The Irish Times, put the national average for new tenancies at €1,839 a month, up 9.1% on a year earlier, against €1,513 (up 4.2%) for existing tenancies. Daft.ie's advertised rents rose 4.4% between December and March, the biggest quarterly jump it has recorded since 2002, according to RTÉ. The pace then cooled: Daft's second-quarter report showed a 1.4% rise between March and June, per the Laois Nationalist.
Average monthly rent, Q1 2026 (RTB index)
The lesson for your budget: a cap protects you while you stay. Moving costs you the protection. On those averages, the gap is €326 a month, or €3,912 a year.
FALSE
Myth 8: "The rent tax credit isn't worth chasing, and you can't claim for past years."
Reality: According to Revenue, the Rent Tax Credit is worth up to €1,000 a year per person for 2024, 2025 and 2026, or €2,000 for a jointly assessed couple. That's €83 a month back on your tax for a single renter. It runs for the tax years 2022 to 2028, and Budget 2027 lifts it to €1,150 for single renters and €2,300 for couples from January.
Past years aren't lost. Revenue's claim instructions say PAYE workers can use "Review your tax for the previous 4 years" in myAccount and complete an income tax return for the year. Have your tenancy's RTB number ready. You need an income tax liability for the credit to be worth anything to you.
FALSE
Myth 9: "In a tight market, a landlord can ask for two months' deposit."
Reality: The RTB is blunt: a landlord cannot ask for a deposit of more than one month's rent, and both of you should have a signed, dated receipt. At the end of the tenancy, the deposit must be returned "as soon as possible" unless there is a legal reason to keep some of it, such as arrears or damage beyond normal wear and tear. See the RTB's security deposit guide for the details.
The cap protects you while you stay. On today's averages, moving costs about €3,912 a year.
How much can my rent go up? Your next six years, worked out
Here's what the 2% cap means in euro, using the RTB's Q1 2026 averages. We've set it against a world where rents simply tracked September's 4.1% inflation every year. That second column is hypothetical. Inflation won't stay at exactly 4.1%, and the comparison is there to show what the cap is worth to you, not to forecast anything.
| Starting rent | Max rise next review (2%) | Rent in year 6 under the cap | 6-year total under the cap | 6-year total if rent tracked 4.1% |
|---|---|---|---|---|
| €1,513 (avg existing tenancy) | +€30.26/month (€363/yr) | €1,670 | €114,530 | €120,731 (+€6,201) |
| €1,839 (avg new tenancy) | +€36.78/month (€441/yr) | €2,030 | €139,208 | €146,745 (+€7,537) |
| €2,204 (Daft avg 2-bed apartment, Q2 2026) | +€44.08/month (€529/yr) | €2,433 | €166,837 | €175,870 (+€9,033) |
Method: one review a year at the maximum allowed, six years of 12 monthly payments, figures rounded. The RTB's own rent calculator is the official tool for your exact figure.
Two things jump out. First, a 2% rise on an average rent is about €30 to €45 a month, small enough to plan for if you see it coming 90 days out. Second, the cap's value adds up quietly: over a six-year tenancy, the difference against 4.1% runs to €6,000–€9,000. If you're weighing a move to "save money", put that number next to the €326-a-month new-tenancy premium before you sign anything.
