1890 was repealed following World War II by the Mental Health Act 1959. This Act abolished the Board of Control, and aimed to provide informal treatment for the majority of people with mental disorders, whilst providing a legal framework so that people could, if necessary, be detained in a hospital against their will. It also aimed to make local councils responsible for the care of mentally disordered people who did not require hospital admission.

The Mental Health Act 1983 was formally approved by the monarch on 9 May 1983 and came into effect on 30 September that year. It has been amended many times: notably in 1995, 2001 (via remedial order, issued on the grounds of incompatibility with the European Convention of Human Rights under the Human Rights Act 1998 section 4), 2007 and 2017 via the Policing and Crime Act 2017.
