Healthcare in England is mainly provided by the National Health Service (NHS), a public body that provides healthcare to all permanent residents in England, that is free at the point of use. The body is one of four forming the UK National Health Service as health is a devolved matter, there are differences with the provisions for healthcare elsewhere in the United Kingdom, and in England it is overseen by NHS England. Though the public system dominates healthcare provision in England, private health care and a wide variety of alternative and complementary treatments are available for those willing and able to pay.
