The YHA are apparently determined to put men into female-only dorms.
Trans identifying man Debbie Hayton booked in July 2025:
'On July 16, YHA customer services told me that,
‘You are welcome to stay in our female dormitory, as you are a woman. We split our dorms by gender, and not sex, so our guests can stay in the room they assign themselves with.’
...
'If any guest does not want to stay in a dorm with any other guest, we offer private rooms… We consulted our solicitors while developing the policy to ensure that it was informed by and compliant with law. We consulted other organisations including the NSPCC, Scouts, Mermaids and Gendered Intelligence on different aspects of the policy. We have also taken advice from the Equality and Human Rights Commission. Our policy was considered and approved by our Board of Trustees… We sought legal advice from our solicitors following the Supreme Court ruling, which indicated that no changes to our policy were needed, pending the final updated Code of Practice for services, public functions and associations from the Equality and Human Rights Commission, which we now await.’

So they appear to be breaking the law.
