Direct Answer
When was homosexuality legalised in the UK?
Direct answer
If by legalised you mean partial decriminalisation of sex between men, England and Wales changed the law in 1967. The UK did not reach equality in one step: Scotland, Northern Ireland, age-of-consent reform and later partnership and marriage recognition followed through separate legal routes.

Explanation
The common search phrase legalised can hide several different legal milestones. The Sexual Offences Act 1967 partially decriminalised sex between men in England and Wales, but only for consenting adults over 21 in private and without creating wider equality. Scotland and Northern Ireland followed different legal paths, with Northern Ireland's criminalisation successfully challenged in Dudgeon v United Kingdom. Later reforms lowered and then equalised the age of consent across the UK through the Sexual Offences (Amendment) Act 2000. Legal recognition for same-sex relationships came later again, through civil partnership and staged marriage equality in England and Wales, Scotland, and Northern Ireland.
Timeline Evidence
The Wolfenden Report Published
The Wolfenden Committee reported in 1957 and recommended that private homosexual activity between consenting adults over 21 should no longer be a criminal offence. The recommendation did not immediately change the law, but it created the central law-reform argument that later shaped the Sexual Offences Act 1967.
North Western Homosexual Law Reform Committee Founded
The North-Western Homosexual Law Reform Committee held its first meeting in Manchester on 4 June 1964, with a formal launch later that year. Founded by Allan Horsfall and others to support decriminalisation, it later became the Committee for Homosexual Equality and then the Campaign for Homosexual Equality.
Sexual Offences Act 1967
The Sexual Offences Act 1967 partially decriminalised sex between men in England and Wales, but only under tightly limited conditions. It applied to consenting adults over 21 in private and left major exclusions and inequalities in place, including outside England and Wales.
Landmark Court Case in Northern Ireland
A significant court ruling found that Northern Ireland's criminalisation of same-sex acts breached the European Convention on Human Rights. The case of Dudgeon v United Kingdom, brought before the European Court of Human Rights, compelled Northern Ireland to decriminalise homosexuality and set a powerful precedent for LGBTQ+ rights across Europe.
Lowering of Age of Consent for Same-Sex Relations
The UK lowered the age of consent for sex between men from 21 to 18, a partial step towards equality with the heterosexual age of consent of 16. The measure was fiercely debated in Parliament and passed only with the use of the Parliament Acts. Full parity would not be achieved until 2001.
Equalisation of Age of Consent to 16 (England, Wales, Scotland, NI)
In 2001, the UK equalised the age of consent for sex between men to 16, matching the age for heterosexual and lesbian relationships. This change applied to England, Wales, Scotland, and Northern Ireland, removing a longstanding legal inequality.
Equal Marriage Legalised Across the UK
Marriage equality arrived across the UK through staged legal reform. The Marriage (Same Sex Couples) Act 2013 received Royal Assent for England and Wales, Scotland legislated through the Marriage and Civil Partnership (Scotland) Act 2014, and Northern Ireland followed through 2019 regulations that took effect in January 2020.
Same-Sex Marriage Takes Effect in Great Britain
The first same-sex marriages in England and Wales took place on 29 March 2014 under the Marriage (Same Sex Couples) Act 2013. Scotland's separate Marriage and Civil Partnership (Scotland) Act 2014 then brought same-sex marriage into Scottish law later that year.
Same-Sex Marriage Becomes Legal in Northern Ireland
Civil same-sex marriage became lawful in Northern Ireland on 13 January 2020, after regulations made under section 8 of the Northern Ireland (Executive Formation etc) Act 2019 changed the law. The change followed years of campaigning and completed the legal route to civil marriage equality across the UK.
