Approved Document M

Approved Document M to the Building Regulations (England and Wales), section 4 of the Scottish Technical Handbooks, and Technical Booklet R to the Building Regulations (Northern Ireland) relate to accessibility for all persons entering and using buildings.

These Documents specify the size and location for glazed panels in doors in various situations, in order to promote safety and accessibility. Visual contrast on the leading edge of doors is also included, as are opening and closing forces for ease of door operation, threshold height and door width requirements.

These Approved Documents are not mandatory, they are only guidance. However, they are considered to be the usual means of proving compliance with the Building Regulations.
