The Northern Ireland Public Services Ombudsman is there to make sure the service provided by public bodies in Northern Ireland is fair and efficient. You can complain to the Ombudsman if you believe the Housing Executive or your housing association has handled your case poorly or treated you unfairly.

You can take your case to the NI Public Services Ombudsman if you aren't happy with how the Housing Executive or your housing association handled your complaint.
