Workplace facilities — toilets, changing rooms, showers, communal spaces — are where trans inclusion becomes most concrete and most contested. This page sets out the framework that actually holds: a dignity-first, case-by-case approach grounded in the Equality Act 2010 and the current EHRC Services Code. The worked walkthrough — the step-by-step decision a manager takes when a real case arrives — is held back, because that is what the manager decision framework and the Policy Hardener deliver.
Start from dignity and inclusion
The starting presumption is inclusion. A trans employee should be able to use the facilities appropriate to their presentation, in safety and dignity, unless a specific, evidenced and proportionate reason says otherwise. That is not a soft principle laid over the law; it is the direction the law and current statutory guidance both point. The Equality Act protects gender reassignment as a characteristic in its own right, and the EHRC Code — which an organisation must have regard to — frames single-sex provision as a permissive power, never a duty to exclude.
Why blanket rules are the risk
The clearest exposure an organisation can create for itself is a blanket rule — all trans women here, all trans men there, or a universal alternative provision imposed regardless of circumstance. Blanket rules skip the step the law actually requires: a proportionality assessment made case by case. A rule that says “always” or “never” cannot be a proportionate means of achieving a legitimate aim, because proportionality is by definition fact-sensitive. The manager decision framework sets out why this is the case and what a proportionate approach looks like instead.
The EHRC Code as the current compass
The operative guidance is the EHRC statutory Code of Practice on services, public functions and associations, which came into force on 5 August 2026 and reflects the Supreme Court’s ruling in For Women Scotland. A statutory code is guidance an organisation must have regard to — not law itself — but what binds is the Equality Act as authoritatively interpreted, which the Code explains. For workplace facilities specifically, note that staff facilities sit under the Act’s employment provisions and separate workplace and health-and-safety regulations, not the services Code — a distinction the framework helps you pin down before you apply any test.
The decision is a documented judgement, not a policy line
A defensible facilities decision records the question, the facts, the legal basis, the options considered and the proportionality rationale — at the time it is made. It does not announce a permanent position for all future cases. The reading on the 2025 Supreme Court definition of sex separates what that judgment settled from what is still being worked out, which is the frame any facilities decision has to sit in.
