INDEPENDENT GUIDANCE — not project-specific legal/design advice or a compliance certificate. Check the official current requirements and applicable transition.

Part T concerns toilet accommodation in applicable new non-dwellings and material changes of use. It is not a dwelling standard. Layouts and facilities need to be considered alongside accessibility and sanitary provision; a drawing that appears to fit cubicles does not by itself show that all applicable requirements are satisfied.

WHAT TO CHECK
[ ] Confirm the building use, work type, applicable dates and any relevant exemption.
[ ] Select the current applicable guidance, noting the later corrections to the published tables.
[ ] Coordinate the toilet strategy and layouts with Parts M and G.
[ ] Have dimensions, circulation, fixtures and interfaces checked before detailed procurement.
[ ] Record the accepted layout and verify significant installation changes.

RECORDS TO KEEP
- Toilet strategy and coordinated layouts
- Relevant scope/exemption and design decisions
- Installation and change records

WHEN TO GET SPECIALIST HELP
Obtain competent design and access advice if scope, exemptions or the layout strategy are uncertain. Use the actual official tables, not a reconstructed third-party copy.

SCOPE AND EDITION
2024 document effective 1 October 2024 subject to transition, corrected 1 October 2024 and revised 3 November 2025 for minor changes to tables 4.1 and 6.1. Confirm scope, exemptions and project transition before specifying. Do not present Part T as a dwelling standard. Read alongside Part M accessibility requirements and Part G sanitary provision.
