Insight: Approved Document M – Accessible Doors

Purpose

This briefing document focuses on the requirements for doors under Approved Document M of the Building Regulations 2010. It aims to ensure that doors are designed and installed to be accessible and usable by all individuals, particularly those with disabilities or limited mobility.

Key Requirements for Doors

Approved Document M sets out the following key requirements for doors in both dwellings and non-domestic buildings:
– Sufficient clear opening width to accommodate wheelchairs (typically 775mm to 1000mm depending on context).
– Low thresholds or level access to avoid tripping hazards and allow smooth passage of wheelchairs.
– Adequate space on both sides of doors for approach and operation.
– Easy-to-use door handles (preferably lever type) positioned at accessible heights (generally 900mm to 1100mm above floor level).
– Manifestation (visual markings) on glass doors and panels to improve visibility.
– Doors to be easy to open with appropriate opening forces and closing speeds for those with limited strength.

Internal Doors in Dwellings

For new dwellings, particularly under Category 2 and 3 standards:
– Doors should have minimum effective clear widths when open (ranging from 750mm to 850mm depending on approach).
– There should be adequate space for wheelchair users to approach and operate the door from both sides.

Doors in Non-Domestic Buildings

In buildings other than dwellings:
– Main entrance doors must be accessible to all users, including push-button or automatic options where necessary.
– Corridors and passageways should have doors with clear widths that accommodate users with mobility aids.
– Fire doors must balance fire protection with accessibility, using appropriate closers and hold-open devices.
