There is no single official average rent increase for Kilkenny, as changes vary by property type, location and tenancy. The RTB Rent Index provides current market-rent figures and trends for Kilkenny, which can help you compare your rent with similar properties. For most private tenancies, rent can generally be reviewed only once every 12 months and the increase is capped at the lower of inflation or 2%, subject to the applicable rules and exceptions. Check the latest RTB guidance or speak to a qualified solicitor if you believe a proposed increase is unlawful.
