British Code of Practice for Women's Spaces Comes into Force

More than a year after the UK Supreme Court ruled that the term "sex" in the Equality Act refers to biological sex, the practical implications of that ruling have taken effect as of 5 August 2026. The Equality and Human Rights Commission (EHRC), the UK's equality watchdog, has brought an updated code of practice into force stipulating that single-sex facilities — from toilets and changing rooms to hospital wards, women's shelters, sports clubs and fitness centres — must be organised according to biological sex, not self-identified gender identity.

What exactly is changing

The code applies to public-facing facilities in England, Wales and Scotland and is the direct result of the ruling handed down by the Supreme Court in April 2025 in the For Women Scotland case. That ruling established that the terms "woman", "man" and "sex" in the Equality Act 2010 refer to biological sex. The EHRC was subsequently tasked with translating that legal position into practical guidance for those managing public spaces: under the code, a trans woman may therefore no longer use a women's toilet or changing room designated as a single-sex facility.

The code attempts to balance two interests. On the one hand, a space designated as a women's space must remain reserved for biological women. On the other, the EHRC acknowledges that forcing transgender people to use facilities designated for their birth sex may itself amount to discrimination. As a practical solution, the commission recommends that, wherever possible, facility managers provide additional gender-neutral facilities — a single lockable room alongside the existing men's and women's toilets, for example — so that no one is effectively left without access to a facility. The content of the guidance and the reasons behind it are explained in more detail at vrouwenruimtes.nl.

Opposition in Parliament

The introduction of the code has not been without controversy. Before it came into force, 167 British MPs signed a motion stating that the guidance "is unworkable" and should be scrapped in its entirety. They are particularly concerned about implementation problems for smaller organisations — hospitality businesses, community centres and smaller sports clubs — that lack the resources to create a gender-neutral facility in addition to existing single-sex facilities. In contrast, a UN human rights expert called on politicians in July 2026 to maintain the code in full, arguing that protecting single-sex spaces is a necessary condition for the safety and privacy of women and girls.

The debate is not confined to Westminster. Several local authorities, including Darlington, have now publicly stated how they intend to apply the code locally in municipal buildings, swimming pools and sports facilities. Women's organisations such as Sex Matters and Woman's Place UK, which have campaigned for years for a stricter, birth-sex-based interpretation of the Equality Act, describe the code's entry into force as a late but necessary correction to a practice in which access to women's spaces has increasingly been determined on the basis of self-identification in recent years, without legal justification.

Significance for the Dutch and Belgian debate

The British code of practice has no direct legal effect in the Netherlands or Belgium, but the debate surrounding it is being followed there. Belgium has had self-identification since 2018: legal sex registration can be changed on the basis of an individual's own declaration, without medical requirements. In the Netherlands, the Transgender Act of 2014 still requires an expert's statement; the bill that would have introduced self-identification was withdrawn in 2025. Neither country has an equivalent of the British code of practice that explicitly links access to single-sex spaces to biological sex. The British development shows that, after initially opting for a broad interpretation of gender inclusion, the United Kingdom has now reached a different balance through the courts. Whether that example will be followed in Dutch or Belgian legislation is not currently under consideration, but the British case does show what implementation questions arise once a country makes a decision in this direction.
