Step 1 of 8
Approximate stair width at the narrowest point?
This is a guide, not a clinical or installation assessment. A home survey confirms suitability.
How wide do stairs need to be for a stairlift?
It depends on the model. Some fit staircases as narrow as 610mm at the narrowest point (the Access BDD Flow X), while others need more room, for example 740mm for the Access BDD HomeGlide. Slimline and perch models suit tighter stairs, so measure carefully and ask for a survey.
Can you fit a stairlift on curved stairs?
Yes. A curved stairlift runs on a rail made to measure for your staircase, so it can follow bends, landings and spiral stairs. It costs more and takes longer to install than a straight stairlift.
What if the user can't bend their knees?
A perch or standing stairlift lets the user lean against a small seat instead of sitting fully. It suits people with stiff knees or hips, and staircases too narrow for a standard seat.
Can stairlifts be fitted outdoors?
Yes. Outdoor stairlifts have weatherproof covers and sealed parts for garden steps and exterior stairs. They usually cost a little more than the indoor equivalent.

Get an Exact Stairlift Assessment
This checker gives you a good idea of what will fit, but only a home survey can confirm it. An installer measures your stairs, checks the top and bottom landings, and looks at doors and radiators nearby. You get a written price for the exact model. The survey is free and there's no obligation.
