That's the conclusion I have come to after reading the document they supplied in response to my FOI request for the Equality Impact Assessment for their 'Delivering Same-Sex Accommodation' policy.
They list each of the protected characteristics and how they think they will be affected by the policy. This is what they say about sexual orientation (my bold):
5.9. Sexual orientation– Significant as this is the reason the guidance exists.
a) Does the equality group face discrimination in this work area?
The guidance in this area is not new, it is clear on the legal position of trans patients in line with the Equalities Act 2010 and provides advice to staff on accommodating patients. The guidance exists to ensure all patients are treated in a way that protects their privacy and dignity.
