If you have tried to understand what has happened to UK trans rights over the past year, you may have encountered one problem: almost everybody seems to explain it differently.
Headlines have sometimes suggested that trans people have suddenly lost all legal protection.
Others have suggested that practically nothing changed.
Neither description is particularly useful. The reality is more specific.
Following the UK Supreme Court’s April 2025 judgment on the meaning of sex under the Equality Act 2010, the Equality and Human Rights Commission has now published an updated statutory Code of Practice for services, public functions and associations.
That Code came into force on 5 August 2026.
So what has actually changed?
1. UK Trans Rights: What Did the Supreme Court Decide?
The Supreme Court considered what the words “man”, “woman” and “sex” mean under the Equality Act 2010.
The Court unanimously ruled that, for the purposes of that Act, those terms refer to biological sex.
That interpretation also applies to trans people who hold a Gender Recognition Certificate.
So, under the Equality Act, a GRC does not change the sex category used for the Act’s sex-based provisions.
That was the central legal question.
2. Does That Mean Trans People Lost Protection Under the Equality Act?
No.
This is one of the most important points to understand.
The Supreme Court explicitly stated that its interpretation does not remove legal protection from trans people.
Gender reassignment remains a protected characteristic under the Equality Act.
Trans people may also have protection through provisions concerning discrimination, harassment and, in relevant circumstances, sex discrimination.
So:
Did the definition of sex change in how the Act is interpreted? Yes.
Did transgender people cease to have protection from discrimination? No.
3. What Is the New EHRC Code?
The Equality and Human Rights Commission updated its statutory Code of Practice following the judgment.
It came into force on 5 August 2026 after receiving ministerial approval and being laid before Parliament.
The Code provides guidance to organisations providing services, carrying out public functions and operating associations on how they should comply with the Equality Act.
And there is another important distinction: the Code itself does not create new law.
The EHRC explicitly says it does not impose new legal obligations.
Instead, it explains how existing law should be understood and applied following legal developments including the Supreme Court judgment.
4. What Does It Say About Gender Recognition Certificates?
The updated EHRC Code reflects the Supreme Court’s interpretation.
For the purposes of the Equality Act, obtaining a GRC does not alter the person’s sex for the Act’s sex-based provisions.
Importantly, the EHRC also makes clear that the Code deals specifically with the Equality Act.
It does not determine every possible legal consequence of a Gender Recognition Certificate under every other piece of UK legislation.
That distinction tends to disappear in social-media arguments.
Legally, it matters.
5. Are Trans People Still Protected From Harassment?
Yes.
The Equality Act continues to prohibit harassment connected with protected characteristics, including gender reassignment.
The new Code provides guidance on harassment, sexual harassment and less favourable treatment following harassment.
Organisations therefore cannot interpret the Supreme Court decision as permission to harass, humiliate or indiscriminately exclude transgender people.
6. What About Single-Sex Spaces?
This is one of the most contested consequences of the judgment.
The Equality Act already contains provisions allowing certain single-sex services in particular circumstances.
The Supreme Court’s interpretation means that when the Act refers specifically to sex, those provisions are now applied using biological sex as defined by the Court.
That does not mean every organisation must automatically operate every service in exactly the same way.
Decisions still have to comply with the Equality Act and the relevant legal tests.
This is one reason the EHRC Code is important: it attempts to provide organisations with practical guidance rather than leaving them to interpret headlines.
7. Why Is There Still So Much Confusion?
Because several different questions are frequently being treated as if they were one question.
There is:
the definition of sex under the Equality Act; protection from gender reassignment discrimination;
Gender Recognition Certificates;
single-sex services;
workplace rules;
privacy;
harassment;
and the application of other legislation.
One Supreme Court judgment did not turn all of those into the same legal issue.
And the updated Services Code itself does not cover employment guidance, which the EHRC says will be updated separately.
What Has Changed — In Simple Terms
The shortest accurate explanation is probably this:
Sex under the Equality Act: interpreted as biological sex.
Gender Recognition Certificate: does not change that Equality Act sex category.
Gender reassignment protection: still exists.
Protection from discrimination and harassment: still exists.
New EHRC Code: now provides statutory guidance on applying the existing law to services, public functions and associations.
Employment guidance: further updates are still expected.
The Debate Is Not Over
The Supreme Court answered a specific legal question.
It did not resolve the wider social and political debate surrounding transgender rights in Britain.
That debate is likely to continue in courts, workplaces, universities, public services and Parliament.
For trans people themselves, however, it is important that discussion of the judgment does not erase one basic fact:
trans people remain protected by the Equality Act.
Understanding what changed matters.
Understanding what did not change matters just as much.
