Handrail height in the UK: a practical guide for stairs

If you’re fitting a stair handrail, getting the height right makes a big difference to comfort, safety and confidence. This guide explains common UK guidance for stair handrail height, plus a simple way to measure it accurately.

Recommended handrail height (UK)

For most staircases, guidance commonly places the top of the handrail at 900mm–1000mm above the pitch line (the line that joins the stair nosings). On landings or level areas, measure vertically from the finished floor to the top of the rail.

Note: requirements can vary by building type and location (and guidance differs across the UK). If you’re unsure, check with your installer or local building control.

Where do you measure from?

  • On stairs: measure vertically from the pitch line up to the top of the handrail.
  • On landings/level floors: measure vertically from the finished floor to the top of the handrail.

                                               

Do you need one handrail or two?

As a practical rule of thumb, wider staircases often benefit from a handrail on both sides for easier support. If you’re working to specific requirements (commercial / public settings), check the relevant guidance for your project.

Should the handrail extend beyond the first/last step?

In many settings, guidance often shows the rail continuing beyond the first and last nosing to provide support as you step on and off the staircase. In homes, where space can be tighter, aim for a rail that feels continuous and supportive over the usable section of the flight.

Quick checklist for a “feels right” install

  • Keep it consistent: keep the rail height the same along the whole flight.
  • Make it easy to grip: choose a profile that feels secure in the hand.
  • Finish ends neatly: avoid sharp edges or snag points.
  • Fix into something solid: use appropriate fixings for your wall type.
