Actually Infuriating

Don’t take my word for it.

The vast majority of public NHS funding comes from general taxation and National Insurance contributions. A small proportion of funding (1% of the total Department of Health and Social Care budget in 2022/23) comes from patient charges for services such as prescriptions and dental treatment. The level of NHS funding in a given year is set by central government through the Spending Review process.

The National Health Service (NHS) is the publicly funded healthcare system in England, and one of the four National Health Servicesystems in the United Kingdom. It is the second largest single-payer healthcare system in the world after the Brazilian Sistema Único de Saúde. Primarily funded by the government from general taxation (plus a small amount from National Insurance contributions), and overseen by the Department of Health and Social Care, the NHS provides healthcare to all legal English residents and residents from other regions of the UK, with most services free at the point of use for most people.[4] The NHS also conducts research through the National Institute for Health and Care Research (NIHR).[5]
