Key Points
- Gender surgery in the UK began in the 1940s. Sir Harold Gillies operated on Michael Dillon in that decade and on Roberta Cowell in 1951.
- The NHS gender identity clinic dates back to 1966. The clinic that began at Charing Cross Hospital in London is the oldest gender clinic in the UK.
- The law changed in the 2000s. The Gender Recognition Act 2004 allowed legal recognition, and the Equality Act 2010 made gender reassignment a protected characteristic.
- Care for under-18s changed in 2024. The Gender Identity Development Service closed in March 2024, the Cass Review reported in April 2024, and puberty blockers are no longer routinely prescribed to under-18s for gender dysphoria.
- The Supreme Court ruled on the meaning of “sex” in 2025. It held that “sex” in the Equality Act 2010 means biological sex, and that trans people remain protected from discrimination on the ground of gender reassignment.
- Adult NHS services are being reorganised. Following the Levy review, NHS England has introduced a single national waiting list and is raising the referral age to 18 and ending self-referral.
Transgender healthcare in the UK began with a small number of operations in the 1940s and early 1950s, became an NHS specialist service when a gender identity clinic opened at Charing Cross Hospital in 1966, and has been shaped by court rulings and legislation from 1970 onwards. Since 2024 it has gone through its largest reorganisation in decades, with new children’s services after the Cass Review and, in 2026, a single national NHS waiting list for adults.
This guide sets out the key dates in order, each checked against official sources such as legislation.gov.uk, NHS England and the courts. If you are considering gender-affirming surgery in London, the final section explains how private care fits alongside the NHS today.
When Did Gender Reassignment Surgery Start in the UK?
The first documented gender surgery in the UK took place in the 1940s. Michael Dillon, then a medical student, had a double mastectomy in the early 1940s and went on to have a series of reconstructive operations with Sir Harold Gillies, the surgeon often called the father of modern plastic surgery[1][2]. Around 1944 Dillon legally became Laurence Michael Dillon, and in 1946 he published Self: A Study in Ethics and Endocrinology[2].
In 1951 Gillies completed surgery for Roberta Cowell, which the Thackray Museum of Medicine describes as the first operation of its kind in Britain[1]. Operations like these were rare and legally uncertain; Gillies was initially hesitant to operate on Cowell for that reason[1].
When Did the NHS Start Providing Transgender Healthcare?
NHS involvement dates back to 1966, when a gender identity clinic opened at Charing Cross Hospital in London[3][4]. It remains the largest and oldest gender clinic in the UK, now based at the Tavistock Centre in north London[3]. Other NHS gender dysphoria clinics have opened since, including five new clinics in the five years to 2025[16].
Adult NHS gender care in England is commissioned by NHS England under two service specifications, one for non-surgical care and one for surgery. The surgical specification, dating from 2019, covers chest reconstruction (mastectomy) for people assigned female at birth and genital surgery. It lists breast augmentation and facial feminisation surgery, including thyroid chondroplasty (tracheal shave), among the procedures that are not routinely commissioned[9]. Our guide to NHS vs private top surgery in the UK compares the two routes in more detail.

How Has UK Law on Gender Changed?
Corbett v Corbett (1970). The first case in which an English court was asked to decide a person’s sex concerned the marriage of April Ashley, who had had surgery in 1960. Judgment was given on 2 February 1970: the court held that her legal sex was male, based on chromosomes, reproductive organs and genital anatomy at birth, and the marriage was annulled. For more than three decades this meant that medical transition did not change a person’s legal sex[5].
Goodwin v United Kingdom (2002). On 11 July 2002 the European Court of Human Rights found that the UK’s failure to recognise Christine Goodwin’s gender breached Article 8 (private life) and Article 12 (the right to marry)[7].
Gender Recognition Act 2004. The UK’s response allowed people to apply to a Gender Recognition Panel for a Gender Recognition Certificate. The panel must be satisfied that the applicant has or has had gender dysphoria, has lived in the acquired gender for two years, and intends to do so permanently. Surgery is not one of the criteria[8].
Equality Act 2010. Section 7 made gender reassignment a protected characteristic, covering anyone proposing to undergo, undergoing or having undergone a process to reassign their sex. It came into force on 1 October 2010[10].
For Women Scotland (2025). On 16 April 2025, in For Women Scotland v The Scottish Ministers [2025] UKSC 16, the Supreme Court unanimously held ↗ that the terms “man”, “woman” and “sex” in the Equality Act 2010 refer to biological sex. The court also stated that this interpretation does not remove protection from trans people, who are protected from discrimination on the ground of gender reassignment, with or without a Gender Recognition Certificate[17].
What Did the Cass Review Change for Under-18s?
NHS gender services for children were provided for many years by the Gender Identity Development Service (GIDS) at the Tavistock and Portman NHS Foundation Trust. In December 2020 the High Court, in Bell v Tavistock, set out what a child under 16 would need to understand to consent to puberty blockers; in September 2021 the Court of Appeal overturned that guidance, leaving consent to clinicians’ judgement[11].
In March 2024 NHS England published a clinical policy stating that puberty suppressing hormones are not available as a routine commissioning option for children and young people with gender incongruence or gender dysphoria[12]. GIDS closed on 31 March 2024, and new regional services in London and the North West opened on 1 April 2024. The final report of the independent review led by Dr Hilary Cass ↗ was published on 10 April 2024[13].
The government then restricted private prescribing. Emergency restrictions on puberty blockers for new under-18 patients with gender dysphoria began in June 2024[14]. On 11 December 2024, acting on advice from the Commission on Human Medicines, the government made them indefinite from 1 January 2025, with a review due in 2027. Patients already receiving these medicines on the NHS, and people taking them for other conditions, are not affected[15].
How Long Is the NHS Waiting List for Gender Services?
On 15 September 2025 the government said that some patients in the south-west of England were waiting over eight years for a first appointment[16]. In a speech the same day, reported by The Independent, the Health Secretary said that “over 42,000 people are still waiting, often for years, for their first appointment at adult gender dysphoria clinics”[18].
The 2025 operational and delivery review of adult gender dysphoria clinics, led by Dr David Levy ↗, was published on 18 December 2025[19]. In response, NHS England and the government set out four immediate priorities: a single national waiting list from April 2026, a referral age of 18 to match the age of discharge from children’s services, an end to self-referral, and productivity goals for every service. NHS England also said that surgical units would take on responsibility for assessing suitability for surgery[20].
In practice, the new referral arrangements were introduced in phases from 17 August 2026. From 1 October 2026, adult gender services stopped taking referrals directly, and referrals now go to one national waiting list managed by the NHS Gender National Referral Support Service[21][22].
How Does Private Gender-Affirming Care Fit In Today?
Alongside the NHS, adults can see private providers for hormones and surgery, which are self-funded and set their own waiting times and referral requirements. Some procedures, such as breast augmentation and facial feminisation surgery, are not routinely commissioned by NHS England, so people who want them usually pay privately[9].
At Centre for Surgery, GMC-registered surgeons perform gender-affirming chest and facial surgery for adults aged 18 and over: FTM top surgery, non-binary top surgery, MTF top surgery, facial feminisation surgery and tracheal shave. No diagnosis, GP referral or WPATH letter is needed, and the consultant who assesses you performs your surgery. Our guide to the WPATH letter for top surgery explains what these letters are and when they are asked for. Centre for Surgery does not offer genital (bottom) surgery.
Frequently Asked Questions
When did trans surgery become available in the UK?
Individual operations took place from the 1940s: Michael Dillon had a series of operations with Sir Harold Gillies in that decade, and Gillies completed Roberta Cowell’s surgery in 1951. An organised NHS route began in 1966, when a gender identity clinic opened at Charing Cross Hospital in London.
Where were the first trans surgeries?
In the UK, the first documented operations were carried out in the 1940s by Sir Harold Gillies, a pioneer of plastic surgery, for Michael Dillon, followed by surgery for Roberta Cowell in 1951. Some early British patients travelled abroad: April Ashley, for example, had surgery in 1960 with the French gynaecologist Dr Georges Burou.
Does the NHS fund transgender operations?
Yes, for some procedures. NHS England commissions chest reconstruction for people assigned female at birth and genital surgery for adults on the NHS gender pathway. Breast augmentation and facial feminisation surgery, including tracheal shave, are not routinely commissioned. Referral is now through a single national waiting list, and waits for a first appointment have run to several years.
What is the NHS policy on transgender people?
Adults in England are referred to NHS gender dysphoria clinics through one national waiting list managed by the NHS Gender National Referral Support Service. Following the Levy review, the referral age is being raised to 18 and self-referral is ending. Under-18s are seen by NHS children and young people’s gender services, where puberty blockers are not routinely prescribed.
What did the Supreme Court rule about the Equality Act in 2025?
On 16 April 2025, in For Women Scotland v The Scottish Ministers, the Supreme Court held that “man”, “woman” and “sex” in the Equality Act 2010 refer to biological sex. It also stated that trans people remain protected from discrimination on the ground of gender reassignment, with or without a Gender Recognition Certificate.
Can you self-refer to a gender clinic in the UK?
NHS England is ending self-referral to adult gender services following the Levy review, and adult referrals now go through a single national waiting list, usually from a GP or other healthcare professional. Private providers set their own rules. At Centre for Surgery you can book a consultation directly for chest or facial surgery, with no diagnosis, GP referral or WPATH letter needed.
