Approved Document M: Access to and use of buildings, Volume 2: Buildings other than dwellings.

Volume 2 supports requirements M1, M2 and M3 of Schedule 1 to the Building Regulations 2010 for buildings other than dwellings. It took effect on 1 October 2015. The July 2020 amendments changed paragraphs 5.6 and 5.7 so that Changing Places toilets are provided in appropriately sized, publicly accessible buildings. The May 2024 amendments, in force from 1 October 2024, updated references to reflect the new Part T and Approved Document T on toilet accommodation.

One of the stated objectives is that elements of the building should not be a hazard to people with impaired sight and should instead assist in wayfinding. That line is worth quoting in a design and access statement.

The signage provisions are scattered, so specifiers tend to miss them. Paragraphs 2.5 and 2.7 deal with signposting accessible entrances. Paragraph 3.5 asks that information about the building can be obtained from reception or from notice boards and signs. Paragraph 3.18 covers lift signage and floor identification at landings. Further provisions cover clearly signed setting down points, signed steps alongside ramps, and the signage of hearing enhancement systems.

For the design of the signs themselves, Volume 2 defers to BS 8300, Inclusive Mobility and the Sign Design Guide. It also notes that BS 8300 contains material beyond what the Approved Document asks, and that following BS 8300 is good practice but not automatically the same as compliance with AD M.

The definition of contrast visually in Section 0 is the figure everyone quotes. It applies to door furniture, handrails, nosings, lift controls, glazing manifestation and the elements a sign sits against. Internal and external stairs need permanently contrasting nosings, and handrails should contrast with their background. Stair geometry itself has moved to Approved Document K, so check both documents for any stair that forms part of an accessible route.
