PART M · Access and use
Accessible toilet requirements explained
An accessible toilet needs more than a large room and a grab rail. The route, door, layout, fittings and usable space must work together for the intended users. Part M provides relevant access and use guidance; Part T has a different role in toilet accommodation.
What should the design consider
The designer should identify the applicable building type and provisions, then show the approach, door operation, transfer space, fittings and controls. Dimensions should reflect the completed room.
For example, a radiator, bin or cupboard can occupy space the drawing assumed would remain clear. Review the actual equipment layout before handover.
Is a standard supplier pack enough
A supplier pack can help specify components, but it does not prove the room or route is suitable. Installation positions and available space still need checking against the relevant guidance.
Ask the designer to verify the assembly in the proposed building rather than relying on the pack's name.
How does Part T fit
Part T deals with toilet accommodation in relevant non-domestic projects. It does not replace Part M accessibility requirements. A universal toilet under Part T is not automatically a wheelchair-accessible toilet under Part M.
Check both provisions where applicable. The final layout should explain how the required facilities work together.
Are Changing Places facilities always required
No. Whether particular additional facilities are needed depends on the building and applicable criteria. The Part M guidance should be checked for the specific use and scale.
Do not assume one accessible WC satisfies every requirement, or that every small premises needs the same provision as a large public building.
What should be checked at completion
Inspect the route and room in their furnished condition. Check door operation, fittings, controls and any relevant alarm provision. Keep the agreed layout and make sure essential clear space remains available in normal use.
