Per the Gender Recognition Act 2004 (in effect 2005) in all four constituent countries of the UK. The requirements are as follows:
1. Must be 18 years of age
2. Must have a gender-dysphoria diagnosis
3. Must intend "to continue to live in the acquired gender until death"
4. Has lived in the acquired gender for at least 2 years.
5. If married: must acquire the consent of the spouse.

Eligibility is determined by a Gender Recognition Panel and if approved then one is granted a gender recognition certificate and may change the gender marker on legal documents.

However, on April 16th 2025, the UK Supreme Court ruled that a woman is defined on the basis of “biological sex”. While this still provides some legal gender recognition, it effectively downgrades trans people to not achieve full recognition in law even with a Gender Recognition Certificate.

There are no health facilities advanced enough to administer gender-affirming care.

The Gender Recognition Act 2004 allows for a person to change their legal gender to either 'male' or 'female', there is no third gender option. The law came into effect on 4 April 2005.

In 2021, the UK government said (in response to a petition) that legal recognition of non-binary gender identity would have "complex practical consequences for other areas of the law, service provision and public life", and said that they felt existing legislation allowing people to change their legal gender went far enough. Courts have, however, ruled that people with non-binary identities are protected from discrimination by the Equality Act.

On 4 October 2023, then-Prime Minister Rishi Sunak asserted his stance on gender identity in a speech at the Conservative Party conference, stating it was “common sense” that “a man is a man and a woman is a woman”.

In January 2024, the High Court in London ruled that (in the case of a US citizen trying to have their non-binary identity recognised in the UK), "We have decided that whenever the Gender Recognition Act refers to ‘gender’ it refers to a binary concept – that is, to male, or to female gender. The GRP [Gender Recognition Panel] accordingly, had and has no power to issue a gender recognition certificate to the claimant which says that they are ‘non-binary’".

The act applied to the entire UK, and Scotland's attempts to recognise non-binary genders have all failed.

The 2002 adoption act, which did not take effect until the next year, specifically defined a couple as: "two people (whether of different sexes or the same sex) living as partners in an enduring family relationship", expressly permitting same-sex adoption.

There are no medical facilities for these surgeries to take place.

As a dependent overseas territory, the United Kingdom is responsible for defence.

There are no facilities to donate blood.

UK law does not currently prohibit conversion therapy in any way. Conversion therapy bans have been discussed for many years. PM Boris Johnson promised to ban conversion therapy in July 2020 and this was reiterated in 2021. In March 2022, the plans were dropped, only for a partial U-turn just hours later when the government announced that the ban would go ahead but not cover trans people. On January 17 2023, the government announced they'd pass a new law to include transgender people in the conversion therapy ban.

In July of 2024, new prime minister Kier Starmer announced his government would put forward a bill to ban conversion therapy. This ban would include sexual orientation and gender identity. As of March 2025, this bill is yet to be introduced.
