Building Regulations 2010 as applying in Wales — Welsh Approved Documents G and M

In brief

Building regulations are devolved to Wales, which maintains its own Approved Documents — AD G (sanitation, hot water safety, water efficiency; requirement G4 covers sanitary conveniences and washing facilities) and AD M (access to and use of buildings). Wales has no Part T / Approved Document T equivalent, so the England single-sex toilet requirement does not apply. AD G does not impose a Part T-style single-sex mandate; separate-sex workplace provision in Wales is driven by reg 20 WHSWR 1992 (GB-wide) rather than the building-reg layer. The Equality Act 2010 applies (GB).

Key provisions

• Requirement G4 — Sanitary conveniences and washing facilities (Welsh AD G): Requires adequate sanitary conveniences and washing facilities; does not specify single-sex separation or numbers (those sit in WHSWR reg 20 / BS 6465).

When relevant

Advising on toilet/sanitary facilities for buildings in Wales. Wales has no Part T; AD G G4 covers sanitary conveniences but imposes no single-sex mandate. Especially relevant where a client assumes Part T is UK-wide (it is England-only). Keep the three layers distinct: building-reg (this record, Wales) ≠ workplace-welfare (WHSWR reg 20, GB-wide) ≠ equality law (EA 2010 / FWS / EHRC Code).
