Portsmouth sets out the statutory reach of the Director of Public Health
Portsmouth City Council’s constitution places the Director of Public Health at the center of local health leadership. The role is not ceremonial. It is framed as a statutory chief officer post with direct accountability for the authority’s public health duties, and it carries responsibility across health improvement, health protection and healthcare public health.
In practice, that means the post serves as the principal source of public health advice for elected members and senior officers. The framework also makes clear that the director’s responsibilities are intended to mirror the council’s own public health duties under the National Health Service Act 2006, as amended by the Health and Social Care Act 2012. Local government is not simply hosting a public health title here; it is holding a legally defined command post for population health strategy.
The constitutional language reflects a wider shift in English public health policy after 2012: local authorities became central actors in prevention, protection and service oversight. The director is the professional pivot for those functions, linking policy, commissioning and emergency response into one accountable structure.
Health protection, prevention and the legal duties attached to them
Section 73A(1) of the National Health Service Act 2006 assigns the Director of Public Health responsibility for all of the local authority’s duties to take steps to improve public health. It also covers any public health protection or health improvement functions delegated by the Secretary of State to local authorities by arrangement or under regulations.
Among the mandated services named in the constitution are appropriate access to sexual health services, plans to protect the health of the population, public health advice for NHS commissioners, the National Child Measurement Programme, the NHS Health Check assessment, elements of the Healthy Child Programme and the duty to produce an annual report on the health of the population. The director also has a role in planning for and responding to emergencies that pose risks to public health, and in cooperating with police, the probation service and the prison service to assess the risks posed by violent or sexual offenders.
This is a broad portfolio because population health risk rarely sits neatly inside one service line. Infectious disease control, childhood obesity surveillance, sexual health access, chronic disease prevention and emergency readiness often intersect in the same community. A single officer role that can coordinate those moving parts gives the local authority a clear line of sight over both everyday prevention and acute threat response.
Licensing, maternity support and local scrutiny of public health services
The post also extends into regulatory and service-delivery functions that are easy to overlook but clinically relevant. The Director of Public Health acts as a responsible authority under the Licensing Act 2003, including making representations about licensing applications. In a city setting, alcohol availability, late-night disorder and related injury or violence risks can all become public health issues rather than purely commercial matters.
Where the local authority provides or commissions maternity or child health clinics, the constitution states that the director is also responsible for providing Healthy Start vitamins under the relevant regulations. Small as that may sound, micronutrient access remains part of the prevention toolkit for mothers and young children, particularly where nutritional deprivation can widen health inequalities over time.
Membership of the local health and wellbeing board is another formal duty. That places the director inside the body where joint strategic needs assessments and health and wellbeing strategies are shaped, allowing health priorities to be linked with social care, children’s services and NHS commissioning decisions. In a system that can easily fragment, this role is designed to keep the population perspective intact.
Leadership expectations stretch from outbreaks to inequality reduction
The constitution goes beyond statutory functions and describes the broader leadership expected of the director. Elected members and senior officers are directed to the post for advice on outbreaks of disease, emergency preparedness, improving local health and access to services. The role includes understanding the determinants of health and illness, changing behavior and promoting health and wellbeing in ways that reduce inequalities.
Public health leadership here is explicitly cross-sector. The director is expected to work with children’s services and adult social services, collaborate with NHS colleagues, engage local resilience fora and contribute to safer communities with criminal justice partners and police and crime commissioners. The remit also includes working with civil society to bring wider partners into health improvement efforts.
A single sentence captures the operational reality: this post must translate epidemiology into local action.
The annual reporting duty matters because population health is not static. Trends in smoking, obesity, mental health, infectious disease, dental need and service access can shift quickly, and the report requirement gives the director a mechanism to bring those patterns into the open. It also gives the council a formal basis for scrutiny when services drift away from prevention or equity goals.
Commissioning, service oversight and the public health safety net
The final portion of the constitution lists a series of non-mandatory public health services that local authorities may commission or deliver. These include tobacco control, increasing physical activity, dental public health services, behavioral and lifestyle campaigns to prevent cancer and long-term conditions, comprehensive sexual health services, community safety and violence prevention, alcohol and drug misuse services, assessment and lifestyle interventions within NHS Health Checks, accidental injury prevention, workplace health initiatives, seasonal mortality reduction, efforts to tackle social exclusion, obesity and community nutrition, public mental health services, population-level interventions to reduce birth defects, support for immunization programs and health protection, incidents and emergencies.
The breadth is deliberate. Prevention does not stop at the clinic door, and many of the most durable public health gains come from interventions that act upstream of disease. Tobacco control reduces cardiovascular and cancer burden. Physical activity and nutrition work on obesity, diabetes and musculoskeletal health. Sexual health services and substance misuse care affect both immediate harm and longer-term social outcomes. Mental health, injury prevention and social exclusion complete the picture because health systems absorb the consequences when community conditions deteriorate.
The constitution assigns the Director of Public Health professional responsibility for the effectiveness, availability and value for money of public health services. That combination of duties means the role is both clinical and managerial, both advisory and accountable. It is a position built to judge whether services are reaching the right population, responding to the right risks and delivering measurable public benefit within local constraints.
The document was last updated in March 2020, and its structure leaves no ambiguity about the post’s importance. Portsmouth has defined the Director of Public Health as a legal, operational and strategic authority for the city’s prevention agenda, with responsibilities that extend from outbreaks and emergency planning to service commissioning and inequality reduction. The unresolved issue is not whether the role matters, but how effectively each function is resourced and coordinated when competing local pressures pull the public health system in different directions.
