What the Latest Supreme Court Ruling Means for UK Employers

Earlier this year, on April 15th, the UK Supreme Court issued a significant ruling that’s important for all employers to understand. It clarified that the terms ‘woman’ and ‘sex’ in the Equality Act 2010 refer specifically to biological sex.

So, what does this actually mean?

The case – For Women Scotland Ltd v The Scottish Ministers – concluded that even if someone has a Gender Recognition Certificate (GRC), they are still considered their biological sex for the purposes of the Equality Act.

This ruling has implications for how employers apply sex-based rights and protections, particularly in areas like changing rooms and toilets.

What does this mean for workplace facilities?

The Equality and Human Rights Commission (EHRC) has offered guidance to clarify the practical application:

• Single-sex toilets and changing/washing facilities must be provided where needed and single-sex facilities may only be used by persons whose biological sex matches that of the facility.
• Mixed-sex facilities (e.g. gender-neutral) aren’t compulsory, but relying on these alone could be seen as indirect sex discrimination against women.
• Toilets or changing spaces in lockable, self-contained rooms (not open cubicles) can be used by either sex.

So in short: workplaces need to ensure everyone has access to appropriate facilities – including trans employees – while also complying with sex-based rights under the Act.

What should employers be doing now?

Now’s a good time to check your internal policies and consider a few key actions:

• Review your equality, diversity, and inclusion policies – make sure they’re up to date and reflect both the law and your organisational values.
• Train your managers – line managers should feel confident handling sensitive topics with empathy and clarity.
• Update anti-bullying and harassment policies – and ensure they clearly protect all staff, including trans men and women.

A balanced approach matters

As the CIPD recently put it, employers should take a “balanced and compassionate” approach when applying these changes. While it’s important to stay compliant with the law, it’s equally important to maintain a supportive and inclusive culture where everyone feels respected and safe.

We recommend reviewing your practices around inclusion, and checking whether your team has the right support and training in place to manage sensitive conversations with care.
