The Parliamentary and Health Service Ombudsman has updated its step-by step guides on making a complaint.
The three guides will help complainants and advocacy groups better understand its complaints process and how it operates.
The updated guides explain what the ombudsman considers when looking into a complaint, how decisions are made, what to expect if there is a decision to investigate and the reasons why they might decide not to investigate a complaint.
