Stairlifts for Narrow Stairs: What Your Options Are
There are various options available to fit a stairlift on a narrow staircase – in fact, at Kudos Stairlifts, our range covers 99% of staircases, including options designed to fit spaces as narrow as 61cm. If you live in a Victorian terrace, a converted townhouse, or any period property with a tight, winding staircase, you’ve probably assumed a stairlift simply won’t fit. It’s one of the most common calls we receive, and it’s an understandable worry given how many older homes were built long before accessibility was a design consideration.
The good news is that stairlift technology has moved on considerably. Manufacturers now build specifically for the kind of narrow, boxed-in staircases common in period properties, using slimmer rails, compact folding components and alternative seating positions. This guide walks through exactly what’s available, how narrow is ‘too narrow’, and the important consideration of whether a stairlift will get in the way of everyone else who uses your stairs.
Can You Fit a Stairlift on Narrow Stairs?
In most cases, yes – a stairlift can be fitted on a narrow staircase, provided the staircase meets a minimum working width once obstructions like handrails and radiators are accounted for. As a general guide, a staircase needs at least around 61cm (24 inches) of clear width, though this varies depending on the model, the layout of your stairs, and the measurements of the person who’ll be using the lift.
Curved or winding staircases, common in terraced homes with a turn near the bottom or top, need particularly careful specification, since the chair needs to swivel and navigate the bend safely without overhanging the treads. In a recent Kudos Stairlifts case study on a narrow staircase with a turn, our surveyor measured the tightest point of the stairs, assessed the turns, and confirmed a compact curved stairlift would fit while leaving the rest of the staircase clear.
The only reliable way to know whether your stairs qualify is a home assessment. Our free, no-obligation home assessment is carried out by a trained surveyor, not a salesperson, and includes measuring your staircase at its narrowest point, checking headroom, and identifying any obstacles that could affect the fit before we recommend a model.
What Is the Narrowest Stairlift Available?
The narrowest stairlift we supply and install can be fitted on staircases as tight as around 610mm (61cm) wide. That figure comes from the Flow X curved stairlift, which uses a single-rail system and Advanced Swivel and Levelling (ASL) technology to suit narrow, multi-turn or spiral stairs – it was the model we used in our own narrow staircase case study, fitted along the inner edge of a turn to leave the larger part of the fanned steps free for other household members.
Another strong option for tight period staircases is the Otolift Modul-Air Smart, which has the smallest diameter rail tube of any single-rail stairlift currently on the market, at just 6cm, and is specially designed for narrow and steep stairs. It requires a slightly wider 635mm of clear width, but may suit staircases where its rail profile or seat options are a better fit
It’s worth noting that the ‘narrowest’ option isn’t automatically the ‘best’ one for your home. Different narrow-stair models vary in weight capacity, seat customisation, and price, so it’s worth discussing your specific staircase and needs with one of our assessors rather than assuming the narrowest model is right by default.
Do Slimline Stairlifts Exist?
Yes, slimline stairlifts are a distinct category within our range, purpose-built with narrower rails, slender chair frames and compact folding parts to suit tight staircases. The British-manufactured Platinum Ergo Curve, for example, is specifically designed to fit narrow staircases, combining an ergonomic, space-saving seat with a slim twin-rail design and a lever-linked footplate.
For straight staircases, our Stannah 600 Siena and other models in the range are also built to fit narrower widths, while still meeting full UK safety standards. Slimline design typically combines a narrow-gauge rail sitting closer to the wall, a reduced-depth seat, slim armrests, and a footplate that folds flush when not in use.
Slimline doesn’t mean a compromise on safety or comfort. Every stairlift we supply comes with seatbelts, sensors, and a minimum one year warranty as standard (extended options are available), so choosing a compact model doesn’t mean choosing a lesser one. You can find full details on our stairlift buying guide.
What Width is Needed for Different Stairlift Models?
Each stairlift model has different dimensions, meaning the minimum width required on the staircase varies between models. The table below demonstrates the narrowest width required for each stairlift we offer, which can be referenced when using our simple measuring guide – however, a home assessment is required to confirm which option is most suitable when combined with the user’s seated measurements.

Will It Block the Stairs for Others?
No, a well specified stairlift shouldn’t block the stairs for other household members. When folded, modern stairlifts typically don’t take up much more than 30cm of space, which leaves enough room for other people in the house to use the stairs normally and safely. This is genuinely the single biggest concern we hear from terraced and period property owners, and it’s a fair one – nobody wants to install a lift that turns the staircase into an obstacle course for family, visitors or carers.
Folding mechanisms mean that when the stairlift is parked, the seat, arms and footplate tuck away against the rail. On curved staircases, we always advise fitting the stairlift on the side with the shortest or narrowest steps where possible, leaving the larger area of the treads clear for everyone else to use.
Some models go further still. The Platinum Ergo Ultimate offers a first-step rail start, meaning doorways and obstacles at the bottom of the stairs aren’t an issue, while the other models feature unique start options designed to avoid hinged rails altogether. A good supplier will always assess how the folded lift affects everyday use, not just whether it fits when installed.
Perch Stairlifts: An Alternative Worth Considering
Perch, or standing, stairlifts are another practical answer for very narrow or awkward staircases, since their compact, waist-height seat takes up considerably less space than a full chair. Rather than sitting fully, the user leans or ‘perches’ in a near-standing position, which can also suit those who find bending the knees to sit down, or rising afterwards, uncomfortable or painful.
Because the seated footprint is so much smaller, perch stairlifts are often considered when a staircase is too tight for even a slimline seated model, or where winding sections leave little room to spare. Perch models aren’t right for everyone though; they generally require a degree of balance and confidence standing for the duration of the journey. Our assessor will discuss your mobility needs alongside your staircase dimensions before recommending whether a perch option is suitable, as part of our wider range of straight stairlifts and curved stairlifts.
Getting the Right Fit for Your Home
Every period property is different, and the width of your staircase is only one part of the picture. Bends, landings, door swings and headroom all play a role in which stairlift options are realistically available to you. Rather than assuming your narrow stairs rule out a stairlift altogether, it’s worth having a professional survey carried out, since many staircases that look impossibly tight can still accommodate a slimline, folding or perch model.
At Kudos Stairlifts, we specialise in narrow and awkward staircases typical of terraced and period homes, and we’ll always measure, assess and recommend honestly rather than pushing a one-size-fits-all solution. As a Stannah accredited distributor and Which? Trusted Trader with over 5,000 installations completed, we’re used to finding solutions for staircases other suppliers turn away. Getting expert advice early, including through our free stairlift quote service, means you can weigh up your options properly and choose a stairlift that keeps your staircase safe and usable for everyone in the household.
Narrow Stairlifts FAQs
How narrow can my staircase be and still fit a stairlift?
Around 61cm is the narrowest staircase width a stairlift can work in, covering narrow and spiral staircases. The exact minimum depends on the staircase layout and the seated measurements of the user. A free home assessment allows a qualified surveyor to confirm what will fit safely in your property.
Will a stairlift make my staircase harder for other people to use?
In most homes, no. Current stairlift models take up around 30cm of space when the seat is folded, with the rail along the rest of the staircase typically protruding 20cm from the wall. On the narrowest staircases, a home assessment will confirm the clear walking space you would be left with.
What's the difference between a perch stairlift and a standard seated stairlift?
A perch stairlift has a small, waist-height seat that lets the user travel in a near-standing position, taking up less space than a full chair. Standard seated stairlifts offer a conventional chair with armrests and a footrest, which some users find more comfortable but which needs more room to swivel.
How much does a stairlift for a narrow staircase cost?
New straight stairlifts start from £2,825 and curved stairlifts, including narrow and slimline models, from £4,995. Both prices exclude VAT. Many customers qualify for disability VAT relief, which means no VAT is payable. Exact pricing depends on the model, any additional options such as a powered swivel seat, and whether a refurbished option is suitable for your needs.
Can a stairlift be fitted on a curved or winding period staircase?
Yes, curved stairlifts such as the Flow X or Platinum Ergo Curve are built to follow the exact contours of your staircase, including turns and half-landings common in older homes. Installation requires precise measuring, including a digital survey, so the rail is manufactured to fit your stairs exactly.
Do I need a home visit before choosing a stairlift?
Yes, a home assessment is essential and is provided free of charge and without obligation. A trained technician will measure your staircase at its narrowest point, check headroom and obstructions, and take user-specific measurements, since dimensions alone don’t always capture how a staircase behaves in practice.
