Developments: 2. A dispute has emerged in the United Kingdom regarding the implementation of new guidance from the Equality and Human Rights Commission (EHRC) concerning single-sex spaces. This guidance follows a Supreme Court ruling that defines “woman” under the Equality Act 2010 based on biological sex, suggesting that facilities such as toilets, changing rooms, and hospital wards should be organized according to biological sex. In the healthcare sector, the Midlands Partnership University NHS Foundation Trust (MPFT) reported that it would not immediately change its policies, which currently allow patients and staff to use facilities matching their gender identity. The trust stated it is awaiting further direction from NHS England, which has indicated that updated policies will be published “shortly.” Simultaneously, major British trade unions, including UNISON, Unite, and the National Union of Students, have voiced opposition to the EHRC guidance. UNISON reported that hundreds of members have raised concerns about practical implementation, arguing that the new rules could undermine protections for transgender individuals and noting that some employers have already begun withdrawing workplace policies designed to support transgender employees. ## Timeline ### 2026-08-20: UNISON and other UK trade unions oppose new single-sex space guidance British trade unions, led by UNISON, are opposing new EHRC guidance that prioritizes biological sex for single-sex spaces like changing rooms and hospital wards. 2 sources. https://clstr.news/cluster/unison-and-other-uk-trade-unions-oppose-new-single-sex-space-guidance ### 2026-08-07: NHS trusts face scrutiny over single-sex space policy delays An NHS trust and NHS England face scrutiny over delays in updating single-sex space policies following new EHRC guidance emphasizing biological sex. 2 sources. https://clstr.news/cluster/nhs-trusts-face-scrutiny-over-single-sex-space-policy-delays --- Cite as: UK single-sex space guidance dispute.
