- As of May 21, 2026, the EHRC laid a new Draft Code of Practice before Parliament — the first comprehensive revision since 2011 — clarifying when single-sex spaces may lawfully restrict transgender access under the Equality Act 2010.
- Parliament holds a 40-day review window running through approximately June 30, 2026; if not disapproved, the UK government will set a commencement date for the code to carry full legal weight.
- The UK Supreme Court ruled unanimously on April 16, 2025 that "sex," "man," and "woman" in the Equality Act refer to biological sex at birth — but transgender individuals retain separate, active protections under the gender reassignment characteristic.
- The EHRC used supervised AI technology to analyze more than 50,000 public consultation responses, marking one of the most significant deployments of legal technology in UK public policy development.
What Happened
Fifteen years. That is how long organizations across the United Kingdom — hospitals, schools, sports clubs, women's refuges — operated without a comprehensive update to the official guidance governing single-sex spaces. As of May 23, 2026, that prolonged silence has a definitive answer.
According to reporting by Reuters (via Yahoo News UK and CTV News), the Equality and Human Rights Commission (EHRC) laid its updated Draft Code of Practice before Parliament on May 21, 2026, replacing guidance that had gone unrevised since 2011. The code arrives roughly thirteen months after the UK Supreme Court's unanimous decision, issued on April 16, 2025, in For Women Scotland v The Scottish Ministers. That ruling established that the terms "sex," "man," and "woman" in the Equality Act 2010 refer to biological sex assigned at birth, not to gender identity or the gender recorded on a Gender Recognition Certificate.
The full text of the Draft Code of Practice, published on GOV.UK, permits service providers to exclude transgender people from single-sex spaces — including toilets, changing rooms, hospital wards, women's refuges, and sports facilities — where doing so is proportionate to a legitimate aim such as protecting privacy, dignity, or safety. Blanket exclusions are not authorized; proportionality is the governing legal test for every individual decision. Parliament has 40 days from May 21, 2026 — a window closing around June 30, 2026 — to review the code before the government may schedule a commencement date.
Bridget Phillipson, Minister for Women and Equalities, stated: "The ruling made it clear that sex means biological sex under the Act, and that trans people are still protected by the Act." Independent MP Rosie Duffield, who departed the Labour Party in September 2024 over trans rights disagreements, described the year-long gap between the ruling and formal guidance as "damaging" for organizations and individuals who had been left without clear legal direction.

Why It Matters for You
Building on that Supreme Court ruling, the practical stakes of this code extend to anyone who runs a service, uses one, or advises on one — and the legal technology deployed to shape this policy now has direct implications for how organizations must respond.
Think of the Equality Act 2010 as running on two parallel legal tracks. Track one covers the protected characteristic of sex — now explicitly defined as biological sex at birth. Track two covers the protected characteristic of gender reassignment, applicable to anyone who has proposed, is undergoing, or has undergone a process of reassigning their gender. The Supreme Court ruling clarified where these tracks diverge; it did not eliminate track two. A transgender woman retains full protection against discrimination on the basis of gender reassignment. What the new code governs is the narrower question of when a service operating on track one may lawfully apply biological sex criteria.
The divergence between advocacy interpretations is worth naming directly, because it shapes how organizations will read the code. Sex Matters, an advocacy organization focused on biological sex protections, notes in its published analysis that if a women-only service admits trans women — individuals who are biologically male — it may forfeit its legal qualification as a single-sex service entirely under the Act. That structural consequence carries risk for service providers beyond any single admission decision. Pink News, writing from an LGBTQ+ advocacy standpoint on May 21, 2026, frames the same code as enabling trans people to be "barred" from gendered spaces, emphasizing the exclusionary dimension. Both framings are legally grounded; they illuminate different sections of the same statute. Organizations using legal software to draft or update access policies will need to weigh both interpretive positions against their specific operational context.
United Nations human rights experts warned in February 2026 that frameworks permitting routine exclusion based on appearance or perceived gender characteristics would raise "serious concerns" under international human rights law — a reminder that domestic codes operate within a wider treaty framework that courts may reference in future legal challenges.
The code's reach extends well beyond restrooms. England Netball, as of September 2025, established three distinct participation categories — female, male, and mixed — with the female category limited to players born female regardless of gender identity. In March 2026, NHS England paused issuing new prescriptions of cross-sex hormones to 16- and 17-year-olds, citing a review that found supporting research to be "really weak." These developments indicate a policy environment in which single-sex distinctions are being redrawn simultaneously across sport, healthcare, and public accommodations. The High Court's February 2026 ruling confirmed that the EHRC's earlier interim guidance was lawful, rejecting legal challenges to its validity — meaning the trajectory of this policy shift has now survived judicial scrutiny at multiple levels.

The AI Angle
The EHRC's deployment of supervised AI technology to analyze more than 50,000 public consultation responses represents one of the most consequential uses of AI legal tools in UK regulatory history. Processing that volume of structured and unstructured public feedback through manual review alone would have demanded several hundred analyst-hours at minimum; supervised machine learning compressed that workload substantially while, the EHRC maintains, preserving analytical rigor in the outputs.
This application sits at the intersection of legal software and democratic participation — a use case gaining traction in regulatory bodies but rarely examined in plain terms. As Smart AI Agents observed in its analysis of autonomous enterprise workflows, the shift from AI as a drafting assistant to AI as a high-volume analytical engine is reshaping how institutions process complex inputs at scale. Law firm automation tools built on similar supervised-learning architectures have become standard practice in large-scale contract review; their adoption in public-sector rulemaking is newer and raises distinct questions about transparency and reproducibility that deserve more public scrutiny. Law firm automation applied to rulemaking — rather than litigation support — is a genuinely new frontier.
A separate concern flagged by Biometric Update involves AI-powered gender recognition technology as a potential enforcement mechanism for single-sex spaces. Research cited by Biometric Update found that 90.5% of transgender people believe facial recognition systems can operate from a transphobic perspective — a figure that raises serious questions about whether legal technology designed to verify access decisions would compound discrimination rather than prevent it. Organizations weighing automated verification tools should treat this data point as a significant legal and reputational risk factor before any deployment.
What Should You Do? 3 Action Steps
Organizations operating single-sex services — from healthcare providers to sports clubs to hospitality venues — should review their current access policies against the Draft Code of Practice before Parliament's approximately June 30, 2026 review deadline. The statute reads that exclusions must be proportionate, not merely permissible under a general category; a blanket exclusion policy lacking individual assessment capability is unlikely to survive a proportionality challenge. AI legal tools and legal software platforms designed for regulatory compliance mapping can identify gaps between existing practice and the code's updated requirements far more efficiently than manual policy audits.
Individuals — whether transgender or cisgender — should understand that the April 2025 Supreme Court ruling did not strip transgender people of legal protections. The gender reassignment characteristic remains fully operative under the Equality Act 2010. Any service provider who subjects a trans person to harassment, demeaning treatment, or exclusion outside the narrow proportionate exceptions faces potential liability. Before signing any employment contract, service user agreement, or organizational policy that touches on these rights, advice tailored to the specific facts is essential — generic contract review based on advocacy-source summaries from either side will not substitute for jurisdiction-specific legal counsel.
The 40-day parliamentary review window from May 21, 2026 is the final formal opportunity for Parliament to disapprove the code before the government schedules a commencement date. Compliance officers, HR teams, and practitioners using law firm automation tools to monitor regulatory change should flag this timeline immediately. Once a commencement date is set, the code carries statutory authority; organizations without updated policies will face legal exposure with minimal advance warning. Legal software dashboards and regulatory alert services are the most efficient mechanism for tracking the exact commencement date as it is announced — do not wait for mainstream news coverage to signal it.
Frequently Asked Questions
What did the UK Supreme Court ruling on transgender rights mean for the Equality Act 2010?
On April 16, 2025, the UK Supreme Court ruled unanimously in For Women Scotland v The Scottish Ministers that "sex," "man," and "woman" in the Equality Act 2010 refer to biological sex assigned at birth, not to gender identity or the gender recorded on a Gender Recognition Certificate. The ruling did not remove protections for transgender people — it clarified that those protections arise from the gender reassignment characteristic, a legally distinct category within the same Act. As of May 23, 2026, according to GOV.UK's published draft code, both the sex characteristic and the gender reassignment characteristic remain active and legally enforceable across England, Scotland, and Wales.
Can transgender people be legally excluded from single-sex spaces in the UK under the new EHRC code?
As of May 21, 2026, the EHRC's Draft Code of Practice permits service providers to exclude transgender people from single-sex spaces — toilets, changing rooms, hospital wards, refuges, and sports facilities — where the exclusion is proportionate to a legitimate aim such as protecting privacy, dignity, or safety. Proportionality is the governing legal test; blanket exclusions without individual assessment are not authorized under the code. Transgender people retain rights under the gender reassignment characteristic in all contexts. The High Court confirmed in February 2026 that the EHRC's earlier interim guidance on this point was lawful, rejecting challenges to its validity.
How does the Equality Act 2010 define biological sex versus gender identity for legal purposes?
Following the April 2025 Supreme Court ruling, the Equality Act 2010 now operates with a clear statutory understanding that "sex" means biological sex at birth. Gender identity — specifically, the protected characteristic of gender reassignment — is a legally distinct category covering anyone who has proposed, is undergoing, or has undergone a process of reassigning their gender. A person can hold both characteristics simultaneously. Organizations using legal technology for compliance purposes need to track two separate legal lines of analysis: one governing sex-based service provisions, and one governing gender reassignment protections. These operate in parallel, not in conflict.
Do transgender people still have legal protections in the UK after the Supreme Court ruling?
Yes. As Bridget Phillipson, Minister for Women and Equalities, stated: "Trans people are still protected by the Act." The gender reassignment characteristic under the Equality Act 2010 protects transgender individuals against discrimination, harassment, and victimization in employment, services, and public functions. As of May 23, 2026, according to GOV.UK's published draft code, this dual-protection framework is the operative legal structure. Official statistics place transgender individuals at approximately 0.44% of Scotland's over-16 population, while 2020 data recorded zero trans women serving on Scottish public boards — figures that help contextualize both the scope of the affected population and the concentrated nature of the policy debate around public roles and services.
What qualifies as a single-sex space under UK equality law, and who can lawfully restrict access?
Under Schedule 3 of the Equality Act 2010, certain services — including toilets, changing facilities, hospital wards, women's refuges, sports participation, and some accommodation — may be provided on a single-sex basis, or access by transgender people may be restricted, where that restriction constitutes a proportionate means of achieving a legitimate aim. The EHRC's May 2026 code of practice provides detailed implementation guidance for service providers. Sex Matters notes in its analysis that if an organization operating a women-only service admits individuals who are not biologically female, the service may lose its legal status as single-sex under the Act entirely — carrying compliance and reputational implications for how that service is described and marketed to users.
