As laws and guidance around single-sex spaces continue to evolve, employers are understandably unsure about what exactly they should be doing. Recent court decisions have clarified some points, but official guidance is still in flux. Below is a straightforward breakdown of what you need to know—and the actions that will keep you legally compliant and operationally confident.
The Legal Picture
Sex = Biological Sex
The UK Supreme Court has confirmed that under the Equality Act 2010, “sex” refers to biological sex, not gender identity—even for people with a Gender Recognition Certificate.
But Protection for Trans Employees Still Applies
This does not remove protections for people with the protected characteristic of gender reassignment—meaning employers must continue to avoid discrimination or harassment against trans staff.
EHRC Guidance Is Delayed (and Previously Withdrawn)
The equality regulator released interim guidance in 2025, later withdrawn—but the High Court confirmed that while it existed, it accurately summarised the law. Full updated guidance is still pending, so employers remain in a period of uncertainty.
What Employers Must Do Right Now to Stay Compliant
1. Follow the Workplace Facilities Rules
The Workplace (Health, Safety and Welfare) Regulations 1992 still apply.
This means:
-
You must provide separate toilets for men and women, unless you provide single-occupancy, lockable rooms.
This requirement has not changed.
2. Avoid Blanket Rules or Automatic Bans
- Courts have been clear: Employers cannot simply enforce access strictly by biological sex or apply “blanket bans” on certain groups. Instead, the law expects employers to be measured and proportionate.
3. Take a Case-by-Case Approach
If an issue arises, assess the situation based on:
-
The layout of your facilities (e.g., can you offer private single-occupancy alternatives?)
-
The impact on all individuals involved
-
Whether your actions might unintentionally “out” someone as transgender
This approach helps you stay on the right side of discrimination law.
4. Act Promptly When Concerns Are Raised
Recent Tribunal cases show that employers can get into difficulty when they don’t respond quickly or sensibly to complaints about shared facilities.
For example, in one case, the employer should have temporarily adjusted arrangements while the issue was being resolved—failing to do so contributed to a finding of harassment.
Key takeaway:
When concerns are raised, take interim steps.
They don’t have to be permanent—just enough to reduce conflict while you assess the situation.
5. Review Your Policies, But Don’t Overreact
The EHRC has already contacted organisations whose policies incorrectly claimed that self-identification automatically gives access to single-sex spaces. Those organisations had to remove the wording.
To stay compliant:
-
Ensure your policies reflect the law as it stands
-
Avoid wording that assumes rights the Equality Act does not grant
-
Keep any references to “self-ID” out of access rules
6. Communicate Early and Supportively
Experts strongly recommend that employers:
-
Talk to trans employees proactively
-
Explain that the legal landscape is shifting
-
Reassure them of ongoing protection against discrimination
Having open conversations early helps avoid conflict later.
7. Keep Good Records
Whenever you make a decision about access to single-sex spaces:
-
Document what you considered
-
Note how you balanced everyone’s rights
-
Record any alternatives you explored
Good documentation shows you acted reasonably and proportionately—key to defending future claims.
8. Continue Seeking Legal Advice
Because guidance is missing and case law is still developing, the safest approach is to check your decisions with legal counsel, especially for sensitive or high-risk situations. This is exactly what the EHRC recommends.
