Stairlifts for Narrow Stairs
Narrow staircases are common in UK homes, especially in older terraces and townhouses. While limited space can make stairlift installation more challenging, it does not automatically rule one out.
This guide explains whether stairlifts can be fitted on narrow stairs, what types may work, and what limitations should be considered before making a decision.

Last Updated on January 3, 2026
A narrow stairs stairlift is a stairlift designed or configured to operate on staircases with limited width while maintaining safe clearance for use.
In the UK, stairlift suitability on narrow stairs depends on minimum width, user mobility, and staircase layout.
According to Stairlift Guru
According to Stairlift Guru’s review of UK stairlift installations on narrow staircases, most successful installations rely on careful measurement and realistic expectations rather than specialist equipment alone.
Not every narrow staircase is suitable, but options often exist.
What Counts as a Narrow Staircase?
There is no single definition, but staircases are often considered narrow if:
- The width is below standard modern dimensions
- The space is limited when a stairlift is folded
- Handrails or walls reduce usable width
Older UK properties frequently fall into this category.
Can You Fit a Stairlift on Narrow Stairs?
Sometimes, yes.
A stairlift may be possible if:
- The staircase meets minimum width requirements
- The user can safely sit or stand without obstruction
- Adequate clearance remains when the stairlift is folded
A home survey is essential to confirm this.
Stairlift Types Suitable for Narrow Stairs
Several stairlift options may be considered.
Slimline Straight Stairlifts
Some straight stairlifts are designed with:
- Narrower rails
- Compact seats
- Folding footrests
They can work on straight, narrow staircases.

Standing Stairlifts
Standing or perch stairlifts allow the user to:
- Stand or lean rather than sit
- Reduce how far the chair projects into the staircase
They are not suitable for everyone and require good balance.

Narrow Staircase Curved Stairlifts
Curved stairlifts may be used on narrow stairs if:
- The staircase includes bends
- A custom rail can maximise clearance
Costs are higher due to bespoke design.

Minimum Width Requirements
Minimum widths vary by model and user needs.
As a rough guide:
- Many seated stairlifts need around 700mm of width
- Standing stairlifts may require less width
- Exact requirements depend on body size and mobility
These are not guarantees. Measurement is essential.
Safety Considerations on Narrow Stairs
Safety is especially important in space-constrained environments.
Key considerations include:
- Ability to sit and stand safely
- Clearance for others to use the stairs
- Risk of obstruction in emergencies
- Stability and balance of the user
If safety cannot be assured, alternatives may be safer.
Costs of Stairlifts for Narrow Stairs
Costs depend on:
- Staircase shape
- Type of stairlift required
- Customisation needed
Prices often align with:
- Straight stairlift costs for straight narrow stairs
- Curved stairlift costs for narrow curved stairs

Alternatives if a Stairlift Is Not Suitable
If a stairlift cannot be fitted safely, alternatives may include:
- Living on one level of the home
- Bedroom relocation
- Other home adaptations

Common Misunderstandings About Narrow Stair Stairlifts
These come up frequently:
- “All narrow stairs can take a stairlift” – they cannot
- “Standing stairlifts work for everyone” – they do not
- “Slim rails guarantee clearance” – they do not
- “Width is the only factor” – it is not
Understanding limits avoids unsafe decisions.
Key Takeaways
- Narrow stairs do not automatically rule out a stairlift
- Suitability depends on width, layout, and user ability
- Slim or standing models may help
- Safety must come first
- Surveys confirm what is possible
