How does the NHS work?
The nutshell
The NHS is the UK's public health service. It started in 1948, and most of its care is free to use because taxes pay for it.
Every fact on this page comes from official NHS rules and non-partisan health researchers. Each source tag — like GOV — opens where a fact comes from.
The basics
What the NHS is
NHS stands for the National Health Service. It is the UK's public health service, and it started in 1948. Its job is to look after people's health, from birth to old age. The service is meant to cover most kinds of care and be there for everyone who needs it.GOV
Free when it is used
Most NHS care is free at the point of use. That means there is no bill to pay when a patient sees a doctor or stays in hospital. Care is given by clinical need, which means how ill a person is, not by how much money a patient has.GOVA few things do cost money. In England, most adults pay a set charge for each prescription and for some dental care.KF
How the NHS is paid for
Most of the money for the NHS comes from taxes.HoCThe largest part is general taxation. Some comes from National Insurance, a tax on what workers earn. Only a small part comes from charges like prescriptions.KF
Four NHS systems, one for each nation
There is not one single NHS across the UK. England, Scotland, Wales and Northern Ireland each run a separate health service. Each nation's government sets its own health rules, so care can work in different ways in different nations. All four services are still paid for by UK taxes.NT
- The NHS has offered health care free at the point of use since it started in 1948
- The NHS Constitution says care is available to all and based on clinical need, not on ability to pay
- The vast majority of NHS money comes from central UK taxation, the House of Commons Library records
- There is not a single UK-wide NHS. England, Scotland, Wales and Northern Ireland each run a separate health service, the Nuffield Trust records
- Free at the point of use is not the same as free for everything. In England, most adults pay a set charge for prescriptions and some dental care
- National Insurance is not the main source of NHS money. General taxation provides the largest share, the King's Fund records

What the NHS covers
The NHS Constitution for England sets out what the service is for. It describes the NHS as a comprehensive service, available to all, free at the point of use apart from a few charges that Parliament has approved, with access based on clinical need and not on a person's ability to pay.GOV The same broad ideas run through the health services of all four UK nations, even though the detailed rules differ.
Where the money comes from
The NHS is funded almost entirely from taxation. The House of Commons Library records that the vast majority of NHS funding comes from central UK taxation, with the rest from sources such as patient charges.HoC The King's Fund, an independent health charity, describes the main sources as general taxation topped up by National Insurance, and notes that patients have paid towards some services, such as prescriptions, since 1951.KF
Four systems, not one
Although people often speak of a single NHS, there are four. England, Scotland, Wales and Northern Ireland each run a separate health service. The Nuffield Trust, an independent health think tank, records that since devolution in the late 1990s the four systems have grown apart, developing different ways of organising and paying for care, while all four remain funded by the UK taxpayer.NT One visible difference is charges. Prescriptions are free in Scotland, Wales and Northern Ireland, while most adults in England pay a set fee.
What gets debated
In the UK, little debate is about whether to have an NHS. Most argument is about money and how the service is run. As demand and costs rise, parties disagree about how much to spend, how to bring down waiting times, and how large a part private companies should play in NHS care. The topics on the welfare state and on the NHS across the four nations look at some of these questions.
