The Public Health Agency (PHA) was established in April 2009 as part of the reforms to Health and Social Care (HSC) in Northern Ireland. We are the major regional organisation for health protection and health and social wellbeing improvement. Our role also commits us to addressing the causes and associated inequalities of preventable ill-health and lack of wellbeing. We are a multi-disciplinary, multi-professional body with a strong regional and local presence.


In fulfilling our mandate to protect public health, improve public health and social wellbeing, and reduce inequalities in health and social wellbeing, the PHA works within an operational framework of three areas: Public Health, Nursing and Allied Health Professionals, and Operations. Our corporate and business plans reflect these arrangements and our purpose as an organisation.
