Nosings Regulations

There are two types of staircase nosings - flush nosings and overlapping nosings.  The differences are explained below:

A Section through a staircase (Nosings Regulations)

Flush Nosings

Staircase Building Regulations are covered by further regulations Parts M1 and M2.

Flush Nosing.

From this, building inspectors are now asking for flush nosings in buildings containing flats, (i.e. public stairs where there are no lifts). The objective should be to make reasonable provision for disabled people to visit occupants who live on any storey. Flush nosings should be used on public stairs when a passenger lift is not provided.,This is to eliminate the trip hazard found with standard nosings that overhang the risers.

Pear Stairs have been making more of these this year.

Overlapping Nosings

In a private dwelling, regualtions require a nosing overlap of at least 16mm.


Without a 16mm overhang it would make the overall going on the staircase very long to accomodate at least a 220mm tread.
