A person who provides at any place facilities or services restricted to men does not for that reason contravene section 29(1) if any of the conditions in subsections (1A) to (1C) is satisfied.. . .
The condition is that the place is, or is part of—
(a) a hospital, or
(b) any other establishment for persons requiring special care, supervision or attention.
The condition is that the place is (permanently or for the time being) occupied or used for the purposes of an organised religion, and the facilities or services are restricted to men so as to comply with the doctrines of that religion or avoid offending the religious susceptibilities of a significant number of its followers.
The condition is that the facilities or services are provided for, or are likely to be used by, two or more persons at the same time, and—
(a) the facilities or services are such, or those persons are such, that male users are likely to suffer serious embarrassment at the presence of a woman, or
(b) the facilities or services are such that a user is likely to be in a state of undress and a male user might reasonably object to the presence of a female user.
A person who provides facilities or services restricted to men does not for that reason contravene section 29(1) if the services or facilities are such that physical contact between the user and any other person is likely, and that other person might reasonably object if the user were a woman.
