Door Threshold Sills and the Disability Discrimination Act (2004)

The Disability Discrimination Act (2004) Recommendations

If you are looking to install a threshold weather bar to any property that provides a service to the public, it is imperative to use one that is designed for easy access to anyone with a disability. This is a legal requirement under the Disability Discrimination Act (2004).

The Disability Discrimination Act (2004) states that:

“Where a physical feature (for example, one arising from the design or construction of a building or the approach or access to premises) makes it impossible or unreasonably difficult for disabled persons to make use of such a service, it is the duty of the provider of that service to take the required steps to ensure easy access for all persons.”

Under this Act, “Physical Features” can include building entrances and exits, along with internal and external doors.

Part “M” Approved

Along with complying with DDA regulations, the range of weather bars also come Part “M” Approved. This refers to Approved Document M, a collection of legal documentation based around the “Access to and use of buildings.” Under these regulations, any door threshold within a property’s communal entrance must be “easily accessible.”
