a public service can best be described briefly as
Public service Public service[1][not in citation given] is a service which is provided by government to people living within its jurisdiction, either directly (through the public sector) or by financing provision of services. The term is associated with a social consensus (usually expressed through democratic elections) that certain services should be available to all, regardless of income, physical ability or mental acuity. Even where public services are neither publicly provided nor publicly financed, for social and political reasons they are usually subject to regulation going beyond that applying to most economic sectors. Public policy[2][not in citation given] when made in the public's interest and motivations can provide public services. Public service is also a course that can be studied at a college or university. Examples of public services are the fire brigade, police, air force, and paramedics.
National Health Service (England) The National Health Service (NHS) is the publicly funded national healthcare system for England and one of the four National Health Services of the United Kingdom. It is the largest and the oldest single-payer healthcare system in the world. Primarily funded through the general taxation system and overseen by the Department of Health, NHS England provides healthcare to all legal English residents, with most services free at the point of use. Some services, such as emergency treatment and treatment of infectious diseases are free for everyone, including visitors.[1]
