The National Health Service (NHS) is one of the largest publicly funded healthcare systems in the world. Founded in 1948, the NHS was built on a simple principle:
π Healthcare should be free at the point of use, based on clinical need, not ability to pay.
Whether youβre a UK resident, international student, healthcare professional, or new migrant, understanding how the NHS works can help you access the right care at the right time.
What Is the NHS?
The NHS provides healthcare services to people living in the UK. It covers:
- GP (doctor) services

The NHS is not a single organisation. It is made up of four separate systems, one for each UK nation:
- NHS England
- NHS Scotland
- NHS Wales
- Health and Social Care (HSC) Northern Ireland
Each system is publicly funded but managed slightly differently.
