The Surrogacy Arrangements Act 1985 (c. 49) is an act of the Parliament of the United Kingdom that prohibits commercial surrogacy arrangements.

The act came about as a response to the birth, on 4 January 1985, of Britain's first commercial surrogate baby amid a widespread public outcry.

[1] The act was amended by the Human Fertilisation and Embryology Act 1990 (so that surrogate mothers can always keep the baby if they change their mind)[2] and the Human Fertilisation and Embryology Act 2008.

From 1996-1998 Margaret Brazier chaired a review of surrogacy arrangements.

[3][4] It made a number of recommendations including that only expenses, including loss of earnings, should be paid to surrogate mothers, and that all surrogacy agencies should be registered with the Department of Health.
