In Ireland, a landlord may generally seek to deduct money for rent arrears, unpaid bills agreed under the tenancy, or damage beyond normal wear and tear. They should not charge for ordinary ageing or make unexplained or arbitrary deductions, and should provide an itemised explanation supported by relevant evidence such as receipts, photographs or invoices. The tenancy agreement and the individual facts matter, so keep records of the property’s condition and all payments. If you cannot agree, the RTB’s dispute resolution process can decide the issue; RentWise is not the RTB or a solicitor.
