A landlord may seek to deduct rent arrears, unpaid bills that are the tenant’s responsibility, the cost of repairing damage beyond normal wear and tear, or reasonable cleaning costs where the property was left less clean than at the start. Deductions should reflect the landlord’s actual, reasonable loss rather than routine maintenance, improvements or a penalty. The landlord should provide a clear explanation and supporting evidence, such as photographs, invoices or receipts, while allowing for the age and condition of items. If the deduction is disputed, the outcome can ultimately be decided through the RTB’s dispute resolution process; consider taking advice from a qualified solicitor for complex cases.
