The RTB will penalise you if you treat a fellow human with compassion
During Covid, a Galway landlord did what a lot of us would do. His tenant lost his job and couldn't pay the full rent. The landlord didn't serve notices or start proceedings. He took what the tenant could afford, kept him in his home, and waited. When the tenant got work again, he went back to paying full rent. The shortfall came to EUR 1,836.
When the landlord later claimed it at the RTB, the Tribunal refused (
TR0823-006554, determined January 2024, published May 2025).
The Tribunal called his conduct
"commendable and indeed not required by the Act". Then it held that because he had accepted lower payments and not chased the balance, the two of them had made an agreement, the tenant had relied on it by staying and paying, and the landlord
"was not entitled to agree to one thing, have the Respondent Tenant act on foot of it, and then resile from that". An informal arrangement to pay what he could became a permanent write-off.
The report contradicts its own statement of the law
Here is how the Tribunal itself set out the rule, a few paragraphs earlier:
"the default position is that where there is an agreed rent, there is ordinarily a liability to pay rent unless validly reviewed. Where there is no valid review, a landlord is entitled to payment as agreed."
And again:
"Where parties enter into legally binding arrangements relating to rent and where there is no valid review, they should ordinarily be bound by the rent."
There was no valid review here. No notice, no prescribed form, nothing. On a strict reading of the law,
the one the Tribunal itself recited, the rent stayed as agreed.
What the landlord had done was accept less during a crisis, in a conversation about what the tenant could afford. Whether that was a reduction or a deferral was never written down, and
the Tribunal resolved the doubt against the landlord.
And note what the same report did with the landlord's notice in this same case. There it demanded
strict compliance: no contractor named, notice invalid, no slip rule. Strict law for the landlord's paperwork, flexible equity for the tenant's rent, in one report.
Strict for landlords, flexible for tenants: the pattern
This isn't one odd case. Put it beside others.
A tenant's hardship can't waive arrears, but a landlord's kindness can. In
TR0001367 (Waterford, 2026), a tenant asked for her arrears to be reduced because of her personal circumstances. The Tribunal said it
"does not have any power to waive rent arrears on the grounds of personal circumstances". So the RTB itself can't write off a tenant's arrears out of compassion. But when the landlord does it voluntarily, the RTB holds him to it forever.
The formality only binds landlords. In
TR0001404 (Tramore, 2026), on the landlord's evidence, the tenant agreed a EUR 125 rent increase by email, and they signed a new lease at the higher rent, a lease the tenant drafted herself. The Tribunal struck the whole increase out
because no formal rent review notice had been served: the Act is
"mandatory in this regard and gives the Tribunal no discretion whatsoever". Fifteen months of the increase, EUR 1,875, was knocked off what she owed him. To be fair, the increase was also over the 2% cap, so part of it could never have stood. But the Tribunal didn't trim it to the lawful amount; it struck all of it, on the formality alone.
Now put the two cases side by side. In Galway, the rent went down with no notice, no form and nothing in writing, and the Tribunal held the landlord to it. In Tramore, the rent went up by written agreement, in a signed lease, and the Tribunal threw it out for want of a notice. The Act's notice rule applies to a new rent whichever way it moves.
The RTB enforces it only one way: when the change favours the tenant, informality is enough; when it favours the landlord, nothing short of the prescribed notice will do.
A tenant's conduct isn't agreement; a landlord's is. In https://rtb.ie/disputes/dispute-outcomes-and-orders/adjudication-and-tribunal-orders/?_search=TR0001584 (TR0001584) (Harold's Cross, 2026), tenants paid an increased rent for 18 months. The Tribunal held that
"the fact of payment does not validate a notice that was not validly served, nor does it amount to an agreement to a new rent". Eighteen months of the tenant paying more was not agreement. A few months of the landlord accepting less was.
And the procedure counts one way. The Galway landlord lost his refurbishment notice partly for not naming a contractor or giving a detailed description. In
TR0001367, another Tribunal held that the Act
"does not mandate the identification of a contractor in the absence of one being employed" and does not require
"contractor-level breakdowns", and cured two omitted statements under the slip rule. The Act says
"the name of the contractor, if any". The Galway notice did also lack a professional's certificate and a planning statement, so its outcome can be squared, but the standard applied to the rest of it can't.
Taken one at a time, each of these can be explained. Taken together, every gap in the law is filled in the tenant's favour, and every formality is enforced against the landlord.
In fairness
The Galway Tribunal gave a second reason for refusing the arrears: the landlord had no bank statements or rent account to prove the figure, and four months between mediation and hearing to find them. That's a fair point. But the main finding stands on its own. Even with perfect records, the claim would have failed, because he'd been kind and hadn't chased it.
The landlord's own evidence didn't help him either. He accepted there had been
"some ambiguity", that he'd never told the tenant the balance was outstanding, and that he hadn't intended to chase it until the issue came up at mediation. That's exactly why the advice below matters.
My advice: don't be nice
I never thought I'd write that. But on the RTB's own reasoning, any flexibility you show a tenant can be turned into a permanent concession. A month's grace becomes a rent reduction. Patience becomes a gift. So the safe course is the one nobody wants: enforce the lease as written, from day one. Rent due on the date it's due. Arrears letters when arrears arise.
