Workplaces are required to provide toilet, washing, and changing facilities on a single-sex basis except where these are provided in individual rooms which are lockable from the inside.
Single-sex toilet, washing, and changing facilities in the workplace must be provided on the basis of ‘biological sex’. It is not permissible for employers to allow, for example, trans women to use the women’s toilets, and for those toilets to be considered single-sex for the purpose of the workplace regulations.
The High Court is clear that this does not prohibit providing additional provision which is not single-sex, at [26]:
…although the 1992 Workplace Regulations do prescribe a requirement for “suitable and sufficient” lavatories, and also make express provision for what will amount to “suitable” by reference to separate provision for men and women, they do not prohibit additional provision beyond what is “sufficient”.
The High Court emphasises that this does not mean that trans people will be required to use facilities corresponding with their ‘biological sex’. Sufficient and appropriate provision must also be made for trans employees. At paragraph 42:
“where an employer provides lavatories as required by regulation 20 the consequence will not be that a [trans] person is required to use the lavatory that corresponds to biological sex. Rather, and in addition to complying with the requirement under the 1992 Workplace Regulations for “sufficient” and “suitable” lavatories the employer must also ensure that the lavatory provision he makes is not discriminatory on the ground of gender reassignment”
The High Court considers that this may be achieved via the provision of mixed-sex facilities in addition to single-sex ones [67]. These may be provided on a gendered basis. For example, an employer could provide single-sex women’s toilets alongside women’s toilets which both cis and trans employees were permitted to use.
Employers should consider adapting their facilities to be provided on a universal basis, in individual lockable rooms. This avoids potential claims of discrimination on the basis of sex, gender reassignment, or any other protected characteristic whilst complying with the regulations. It also increases accessibility for many disabled people, who would benefit from lockable facilities with a sink provided, but may not actually require a larger wheelchair-accessible toilet.
