NHS England has told acute, mental health and community trusts, integrated care boards, and providers of NHS-funded care in England that single-sex wards, bays, toilets and staff changing rooms must be provided on the basis of biological sex. The instruction, published on Thursday, applies the ruling of 16 April 2025 in which the Supreme Court held unanimously that the words "sex", "man" and "woman" in the Equality Act 2010 refer to biological sex.
The two documents, Privacy, dignity and safety in hospital accommodation and Guidance on NHS staff facilities, replace the 2019 guidance that governed NHS accommodation for seven years. That guidance told staff that trans patients "should be accommodated according to their presentation: the way they dress, and the name and pronouns they currently use", and that a patient could use the facilities matching their gender identity.
Under the replacement, a trans woman, who remains male for the purposes of the Equality Act while retaining the Act's protection from discrimination because of gender reassignment, should be accommodated in line with biological sex, which in practice means a ward or bay shared with men, or a single room. A different placement is permitted only where an assessment of the individual patient's circumstances makes the biological-sex ward clinically inappropriate. That requirement comes from the guidance, not from the Supreme Court, which interpreted a statutory term rather than imposing a new duty. The conditions under which a separate or single-sex service may lawfully be provided remain those that Parliament set out in the Equality Act 2010.
For female patients, the practical effect is a return to the standard the NHS Constitution has promised since 2012. For female staff, it settles a question that has been tested repeatedly in the employment tribunals, and it does so with language that leaves trusts little room to argue.
The staff guidance states that if a facility is open to women and trans women, or to men and trans men, "it is not a single-sex service under the Equality Act 2010". It requires trusts to review or rewrite their facilities policies in line with the Workplace (Health, Safety and Welfare) Regulations 1992, the Equality Act and the Gender Recognition Act 2004, to audit their provision in detail, including whether hand-washing areas are communal, to complete equality impact assessments, and to commit to reviewing policies within one year.
A ruling Labour took 18 months to apply
The delay is the story that ministers will struggle to explain. When the Supreme Court handed down For Women Scotland Ltd v The Scottish Ministers, Wes Streeting, then Health Secretary, said he would issue guidance "in the coming weeks". It has taken 18 months, and it has been left to his successors to publish it.
Mr Streeting resigned as Health Secretary on 14 May 2026, having lost confidence in the Prime Minister. James Murray was appointed in his place. Mr Streeting returned to government as Defence Secretary in Andy Burnham's cabinet on 20 July, the day Yvette Cooper took the health brief. Responsibility for the delay therefore passed through three health secretaries in 18 months, across two Prime Ministers.
The Equality and Human Rights Commission had already done its part. Its revised Code of Practice for services, public functions and associations, which confirms that single-sex services must be provided on the basis of biological sex, was laid before Parliament on 21 May 2026 and scrutinised for the 40 days that section 14 of the Equality Act 2006 requires. Neither House passed a resolution disapproving it, and the commencement order brought the code into force on 5 August 2026. The NHS then waited a further ten weeks, and even then published guidance rather than a timetable for compliance. As late as August, The Times reported that NHS England had refused to set out a timeline for bringing in single-sex spaces.
Damian Hinds, the Conservative shadow health secretary, told The Independent that the delay had left staff and patients "facing uncertainty over single-sex spaces". The charge is hard to answer, because the Government was not waiting for new evidence. It was waiting, on its own account, for others to act first.
The bill for delay has already been paid by nurses
That cost fell on individual women who were forced to litigate against their own employer. At Darlington Memorial Hospital, eight nurses objected to a colleague who is biologically male and identifies as a woman being allowed to use the female changing room used by around 300 nurses. Under the trust's Transitioning in the Workplace policy, an employee "is regarded as transgender the moment a person informs us they are Trans", after which "the choice should be theirs" over which facilities to use. When the nurses complained, the tribunal found that they were told to broaden their mindsets and offered a former office that was not a compliant changing room.
The tribunal, which sat from 20 October to 11 November 2025 and handed down judgment on 16 January 2026, held that County Durham and Darlington NHS Foundation Trust had harassed the nurses and indirectly discriminated against them on the ground of sex. It found that the trust's policy had been drafted without assessing the impact on women, who make up around 80 per cent of its workforce. It dismissed the nurses' complaints of harassment against the trans-identifying colleague personally, accepting that the colleague was exercising a choice the trust had given. Eight nurses brought claims; the case of one, Joanne Bradbury, was stayed, and the trust paid £187,000 in damages on 24 June 2026 to the seven whose cases were heard. The award did not cover legal costs, which are to be decided separately. That money came from public funds, and it was paid for a policy the trust was never legally required to adopt.
The same ground has been fought in Scotland, where an employment tribunal found in December 2025 that Sandie Peggie had been harassed by NHS Fife after she raised concerns about a trans woman doctor using the female changing room and was suspended for doing so. The tribunal dismissed her other claims of discrimination and victimisation.
Guidance is not the same as a deadline
Three weaknesses in the guidance will determine whether it changes anything on a ward.
The first is timing. The accommodation guidance sets no date by which trusts must deliver single-sex provision. The one-year deadline in the companion document covers the review of staff facilities policies, not the rebuilding or reconfiguration of changing rooms. NHS England has also not said what happens to a trust that reports the same breach in the same bay month after month. The 2019 guidance stated that, under the NHS Standard Contract, "where breaches occur, the commissioner whose patient is affected should levy the financial sanction specified by the Contract". The replacement document omits that section altogether: it sets reporting duties and board oversight, and leaves any financial consequence to the Standard Contract without saying how it will bite. Historically the lever has not worked. NHS England's own figures show 5,520 mixed-sex accommodation breaches in August 2026, against 4,559 in June 2025. Both are counts of unjustified mixing in sleeping accommodation, the definition used since December 2010; under the new guidance every breach must be reported, so the series is about to lose its baseline.
The second is money. The staff guidance states in one paragraph that "organisations are responsible for providing the resources needed to meet this legal duty, whether that is time, capital costs or specialist expertise", and in another that improvements should be "prioritised within their existing budgets". Trusts that have run out of capital will read the second sentence as the operative one. No additional funding was announced alongside the guidance, for the audits, the estate changes or the single rooms that the guidance expects trans patients to be offered.
The third is that NHS England has, in effect, shared the risk. Trusts are told to "continue to seek their own legal advice, including where there are concerns about application within their specific context". Where the law is treated as settled, that instruction is ordinary prudence. Where a trust is left to decide for itself whether an individual placement is lawful, it is an invitation to the same caution that produced the Darlington policy. Maya Forstater, chief executive of Sex Matters, welcomed the guidance as "a momentous shift back to reality" but warned that NHS patient data is "a mess, with potentially thousands of trans-identifying people recorded as the opposite sex".
Where the guidance does not apply
The documents are explicit about the settings that are exempt. Same-sex accommodation requirements do not apply in A&E departments or urgent treatment centres, in adult critical care at levels 2 and 3, in areas delivering active treatment such as chemotherapy, radiotherapy, renal dialysis and same-day emergency care, in children's and young people's units, in areas cohorting patients during an infectious disease outbreak, or where a patient receiving end-of-life care would be moved solely to achieve segregation.
Where the guidance does apply, the list is short and specific: all inpatient ward care in acute and community hospitals, all mental health inpatient units, and day surgery, endoscopy and theatre recovery areas. NHS England also states that same-sex accommodation "should not be a reason for patients to receive care in a non-designated clinical space (corridor care)", a sentence that reflects how far some trusts have drifted from the Constitution's pledge.
Trusts must now identify an executive board lead, report every breach nationally through the Strategic Data Collection System, report all breaches locally in each 24-hour period, and provide regular updates at public board meetings on the numbers. Integrated care boards are told to name an executive board lead of their own and to monitor the delivery of same-sex accommodation through their contracts. The previous regime required only "unjustified" breaches to be recorded nationally, which is the loophole that allowed trusts to characterise mixing as unavoidable without challenge.
Responses
Duncan Burton, the Chief Nursing Officer for England, wrote in his foreword that the guidance "sets out clear principles to help staff make decisions about hospital accommodation" and reflects support for care that protects "the privacy, dignity and safety" of "all patients, including women, men, LGBT+ people, people from ethnic minority and religious communities and people with disabilities".
TransActual and Trans+ Solidarity Alliance said the guidance "leaves individual healthcare professionals unclear on how to safely look after trans patients", that forcing trans people into spaces for their sex assigned at birth "would push trans people away from accessing care", and that it "will not survive contact with reality in resource-strapped hospitals". Stonewall and the LGBT Foundation said the ruling and the guidance were "creating an untenable situation for trans+ and non-binary people" and called for clinicians to consult patients meaningfully. The British Medical Association, which had written to NHS England and the EHRC to raise concerns, said it remained "deeply concerned about the potentially devastating repercussions" for trans patients' access to healthcare and for trans staff, and continues to argue for facilities "in accordance with their gender identity".
Conservative ministers made the first move. On 30 April 2024, Health Secretary Victoria Atkins opened an eight-week consultation on amending the NHS Constitution so that same-sex accommodation and intimate care rested on biological sex, saying "sex matters". Labour's response at the time, from its then shadow health secretary Wes Streeting, was that "rights on paper are worthless unless they are delivered in practice". It took Labour's own government 18 months to write the paper.
Andrea Williams, chief executive of Christian Concern and the Christian Legal Centre, welcomed the guidance but identified the omission that remains: it gives staff no protection over pronoun use. "NHS England must now make clear that healthcare professionals cannot be compelled to use preferred pronouns or penalised for declining to express beliefs about gender identity that they do not hold," she said. Bethany Hutchison, one of the seven claimants and now president of the Darlington Nurses Union, put the same point about enforcement: "The test now is whether NHS trusts will actually follow it. Too many NHS institutions have been ideologically captured on these issues, leaving front-line women to defend rights and protections that their employers should have upheld from the outset."
Great British PAC Reaction
Richard Thomson, National Director of Great British PAC, said:
"We live in disturbing times when this guidance even needs to be issued.
People entering hospital are often frightened, exposed and at their most vulnerable. Any decent, civilised country should protect their dignity, privacy and safety through genuinely single-sex wards, toilets and changing rooms.
Yet Britain needed the Supreme Court to clarify what the law - and basic reality - already made clear: biological sex matters.
Without that judgment, much of our political and institutional class appeared incapable of defining a man or a woman, let alone protecting vulnerable patients.
Eighteen months later, NHS England has finally acted.
This should never have been controversial. It is common sense, human dignity and the proper safeguarding of patients.
On this issue, at least, sanity has finally prevailed."
What happens now
Trusts have been ordered to audit their facilities and to set out how they will comply, and the Government says guidance for other departments, including education, justice and defence, will follow in due course. Parliament will have a say in the machinery: the Health Bill, given a second reading in the House of Lords on 13 October, would abolish NHS England and transfer its functions to the Secretary of State for Health and Social Care and to integrated care boards. The body that issued this guidance may not be the body that enforces it.
None of this settles the question the guidance leaves open, which is what a female patient should do, on a night when the only free bed is in a bay with men, if the trust records the breach, reports the breach and moves nobody.
