A narrow staircase does not necessarily mean you cannot have a stairlift. Specialist slim-rail models are designed specifically for staircases that would not accommodate a standard stairlift. This guide tells you what counts as narrow, which models fit, and what to expect on price.
How narrow is too narrow?
Most standard stairlifts require a minimum stair width of around 70 to 75 cm. Slim-rail models can fit staircases as narrow as 60 to 65 cm. Below 60 cm, installation becomes very difficult. A free home survey will confirm whether your staircase is suitable.
Which stairlift models are designed for narrow stairs?
Handicare 1100: One of the narrowest rails available at just 10.5 cm wide. The Handicare 1100 is specifically designed for tight staircases and includes a fold-flat design that maximises the remaining passable width when the stairlift is parked. Prices start from around £1,800. Available through Handicare’s UK dealer network.
Acorn 130 Slim: Acorn’s narrow staircase variant uses a slimmer profile rail and a folding carriage that tucks away when not in use. Prices from around £1,500. Suitable for staircases down to approximately 65 cm width.
Stannah 260 Slimline: Stannah’s answer to narrow staircases, using a high-mounted rail design that keeps the stair tread clear for other users. Premium build quality at a premium price from around £2,800.
How is staircase width measured?
The relevant measurement is the clear width of the stair tread, measured from the wall to the edge of the tread (not including any banister). Measure at the narrowest point of the staircase, which is usually at a bend or where the balustrade narrows. An installation engineer will take precise measurements during a free home survey before any commitment is required.

Will a stairlift on narrow stairs block other users?
A slim-rail stairlift will reduce the usable width of the staircase when in use. When parked at the top or bottom with the seat, footrest and armrests all folded, most slim models leave at least 45 to 50 cm of clear stair width, which is sufficient for another person to pass. A free survey will confirm whether this is workable for your household.
Can I get a grant for a narrow staircase stairlift?
Yes. The Disabled Facilities Grant covers slim-rail stairlifts as it does all other types, subject to means testing and an occupational therapist assessment. The higher cost of specialist models makes grant funding particularly worth pursuing.
What if my staircase is too narrow for any stairlift?
If no stairlift can be safely fitted, a through-floor lift may be an alternative. These require more structural work but can be funded through the DFG and provide a complete solution where stairs cannot be used at all.
