In a move that could reshape how public services, businesses and charities across Great Britain operate, the Equality and Human Rights Commission has released an updated Code of Practice. This guidance firmly anchors the definition of “sex” in the Equality Act 2010 to biological reality, drawing a clear line after years of legal wrangling and institutional hesitation.
A New Dawn for Single-Sex Spaces
The revised code explicitly states that “sex” refers only to biological sex — not so-called “gender identity.” Private spaces such as bathrooms, changing rooms and hospital wards must align with a person’s biological sex at birth — not their self-identified gender.
This clarification carries significant weight because, as the code emphasizes, allowing biological males in female-only spaces or vice versa effectively nullifies the purpose of single-sex provisions.
The code’s core conclusion cuts through the ambiguity that has lingered for years: “a person’s sex remains their biological sex” regardless of how they feel, and designated spaces should reflect that biological reality.
Equalities Minister Bridget Phillipson welcomed the development as “an important step in ensuring that organizations across Great Britain have clear guidance regarding its implementation, protecting people’s rights across our country.”
