A rough guide to the rules and regulations on staircases, spirals and space savers.


Note: There are a lot of rules governing the installation on all types of staircases, spiral, space saver, straight and winding flights. The information in this guide should not be taken as anything more than just a rough idea on these rules. Before undertaking any staircase work you shold always consult your local building regs officer. Not all staircases in the UK meet building regs in all curcumstances.

This guide will be broken down into types of staircase and a set of general rules as well.



General Rules:
  • Railings should not have spaces that you could fit a sphere of greater than 100mm through
  • Stairs with open risers that are likely to be used by children under 5 should be constructed so that a 100mm sphere can not pass through. ( A riser bar kit can resolve this issue if needed)
  • Railings should not encourage children to climb them.
  • The going should be a minimum of 220mm
  • The rise should be a maximum of 220mm
  • A minimum of 2000mm head room should be allowed, 1900mm for attic stairs
  • The railings should be between 900mm and 1000mm in height

Spiral Staircase Rules:

  • A spiral staircase serving one habitable room should have a 600mm clear width
  • A spiral staircase serving two or more habitable rooms should have a 800mm clear width

Space Saver Rules:

  • These should only be installed when there is not enough room for a normall staircase
  • Space saver stairs should only be used for access to one habitable room, with a maximum of one additional bathroom (e.g 1 bedromm and an on suite)
  • Minimum width should be 600mm
Hopefully this guide will be of use to you in choosing a staircase.
