What we do

The Public Health Agency (PHA) is responsible for providing health protection and health and social wellbeing improvement to every member of every community in Northern Ireland. We are committed to addressing the causes and associated inequalities of preventable ill-health and lack of wellbeing. 
The Public Health Agency was established in April 2009 as part of the reforms to Health and Social Care (HSC) in Northern Ireland. We are a multi-disciplinary, multi-professional body with a strong regional and local presence. 


The PHA operates under a framework of three functional areas: Public Health, Nursing and Allied Health Professionals, and Operations, in order to carry out our mandate to safeguard public health, promote public health and social welfare, and reduce inequalities in health and social wellbeing. Our corporate and business plans reflect these arrangements and our purpose as an organisation. Access our Directorates and Service Areas here
