Trans patients must be accommodated on single-sex hospital wards or bays that correspond to their biological sex rather than their gender identity, according to updated guidance released by NHS England on Thursday.
The new policy states that when placement aligned with biological sex is not "clinically appropriate", alternative arrangements must be provided. However, the guidance emphasises that decisions may need to be assessed individually and must prioritise clinical requirements while safeguarding the dignity and safety of both trans patients and other patients on the ward.
This represents a significant reversal from earlier NHS England guidance, which permitted patients and staff to be placed on wards or access facilities based on their gender identity. Under that framework, a trans woman—a biological male who identifies as a woman—could have requested placement on a women's ward, while a trans man—a biological female who identifies as a man—could have chosen a men's ward.
What triggered the policy change?
The previous guidance was withdrawn following an April 2025 Supreme Court judgment that redefined key terms under equality law. The court ruled that "sex" refers to biological sex and "woman" denotes a biological woman. The judgment further established that for a space or service to be designated single-sex, it must restrict access to individuals of the same biological sex only.
According to the Equality and Human Rights Commission's guidance on single-sex spaces, which came into force just over two months before the NHS update, single-sex services are based on biological sex.
How will the guidance be implemented?
The new NHS England policy emphasises that to prevent discrimination against trans people, gender-neutral spaces should be made available as alternatives. The guidance also recognises that clinical need takes precedence in certain circumstances, particularly in emergency departments and urgent care settings.
Beyond patient accommodation, NHS England has issued separate guidance for trusts on managing changing rooms, toilets and other single-sex facilities for staff. These spaces are also to be allocated based on biological sex rather than gender identity. The guidance encourages NHS trusts to conduct audits to verify they are providing sufficient alternatives to single-sex facilities, such as gender-neutral or single-occupancy toilets.
According to NHS England communications to trusts and integrated care boards, chief executives and boards are expected to take action on the new guidance.
Why is this guidance being issued now?
Hospital capacity constraints have created ongoing challenges in maintaining single-sex ward arrangements. NHS England data reveals that breaches of the previous mixed-sex accommodation guidance—instances where patients of the opposite sex were placed on single-sex wards—have increased annually since 2021. In August 2026, there were 5,520 recorded breaches, compared to 3,853 in June 2025, demonstrating the scale of the problem.
How have stakeholders responded?
Sex-based rights charity Sex Matters has described the guidance as a "momentous shift back to reality", though it has raised concerns about implementation. CEO Maya Forstater stated:
NHS patient data is a mess, with potentially thousands of trans-identifying people recorded as the opposite sex.
Trans rights organisations TransActual and Trans+ Solidarity Alliance have expressed concern that NHS staff may lack clarity on how to safely care for trans patients. They warned:
This guidance will not survive contact with reality in resource-strapped hospitals and will create unworkable operational challenges.
What legal cases have influenced this decision?
The NHS has faced several high-profile legal disputes over the application of equality law and workplace regulations. In January 2026, Darlington Memorial Hospital was found to have breached the dignity of a group of nurses who objected to a transgender colleague—a biological male who identified as a woman—being permitted to use female changing rooms. The nurses were instructed to change elsewhere if they had concerns. An employment tribunal concluded the trust had indirectly discriminated against them.
The nurses are currently seeking £400,000 from the NHS to cover legal costs. Bethany Hutchison, one of the nurses involved and now president of the Darlington Nurses Union, welcomed the "clear and necessary guidance" from NHS England but stressed the importance of enforcement:
The Darlington nurses should never have had to take their own employer to court to secure privacy, dignity and lawful single-sex facilities. Enforcement cannot continue to depend on the courage and personal sacrifice of individual nurses.
In December 2025, an employment tribunal in Scotland found that nurse Sandie Peggie had been harassed by NHS Fife over its interpretation of single-sex space rules. Peggie had raised concerns about a doctor who was a trans woman using female changing rooms and was subsequently suspended. The tribunal dismissed her other claims of discrimination and victimisation. An appeal is currently under way and is expected to reach the courts in the coming year.
What happens next?
NHS England has notified trusts and integrated care boards of the new guidance, with expectations that leadership will implement the policy. The guidance represents the culmination of a review period that began after the Supreme Court's April 2025 ruling, during which NHS England had instructed providers to continue reporting breaches while revised guidance was prepared.
