When stairs are too narrow for a standard stairlift, there are several alternative solutions that can provide safe, accessible access between floors.
These options vary in cost, space requirements, and suitability — but many can work where stairlifts cannot.
This guide explains the main alternatives to stairlifts for very narrow stairs and what you should consider when choosing one.
Key Takeaways
- Some staircases are too narrow or unsafe for stairlifts
- Alternatives include platform lifts, step lifts, ramps, and home modifications
- Each option has different space, cost, and accessibility implications
- A professional mobility assessment helps determine the best choice
- Safety and long-term usability should guide decisions
1. Wheelchair Platform Lifts
Ideal for: Users who use a wheelchair full-time or cannot transfer safely.
What they are:
Platform lifts are vertical or inclined lifts that allow a user to stay in their wheelchair while moving between levels.
Why they’re useful for narrow stairs:
- Some models require less horizontal space than stairlifts
- They eliminate the need to transfer from a wheelchair to a seat
- Great for wheelchair users with limited mobility
Considerations:
- May require more vertical install space
- Can be costlier than stairlifts
- Planning permission might be needed in some cases
2. Step Lifts
Ideal for: Small rises of a few steps where a full stairlift isn’t feasible.
What they are:
Step lifts are small platforms that raise and lower users between a few steps rather than travelling the entire staircase.
Why they’re useful for narrow stairs:
- Compact footprint
- Good for short stair runs
- Can often be installed without major structural changes
Considerations:
- Not suitable for tall staircases
- Best for specific, limited height changes
3. Home Modification (Staircase Alteration)
Ideal for: Long-term solutions where changes to the stairs are feasible.
What it involves:
- Widening stair treads
- Reconfiguring steps or landings
- Adding handrails or altering stair shape
Why it’s useful:
- Creates space for future accessibility solutions
- Maintains clear access for all household members
- Can increase property value
Considerations:
- More costly and invasive
- Requires contractor involvement
- May need building control approval
4. Vertical Through-Floor Lifts
Ideal for: Users who need a wheelchair-accessible, level change without stairs.
What they are:
Vertical lifts move users straight up and down between floors with a compact footprint.
Why they’re useful:
- Often fit into small spaces like closets or en-suite areas
- Do not use stair width at all
- Great for wheelchair users and those who cannot transfer
Considerations:
- Higher cost
- May need planning/building approval
- Best when stairs present significant barriers
5. Inclined Platform Lifts
Ideal for: Users who prefer to stay on a platform but don’t have space for a wheelchair lift.
What they are:
Inclined platform lifts are similar to stairlifts but allow a wheelchair or platform to travel along the stairs.
Why they’re useful:
- Good for narrow stairs with slightly restricted width
- Can be tailored to specific stair shapes
- Provides seated or wheelchair mobility without transfer
Considerations:
- Still needs some stair width
- Usually more expensive than seated stairlifts
6. Portable Ramps and Small Threshold Ramps
Ideal for: Very short step transitions or small rises at external entrances.
What they are:
Strong, portable ramps or modular ramp systems that bridge small level changes without mechanical lifts.
Why they’re useful:
- Budget-friendly
- No installation required
- Useful for small rises where full mobility access isn’t needed
Considerations:
- Not suitable for long indoor staircases
- Can require storage space
How to Choose the Right Alternative
Choosing the best option depends on:
🔹 User Mobility Needs
- Wheelchair user? Consider platform lifts
- Limited but comfortable standing? Step lifts might work
🔹 Available Space
- Vertical options avoid stair width issues
- Inclined platform lifts still need some staircase width
🔹 Budget & Planning Restrictions
- Home modifications cost more upfront
- Portable ramps are cheap but limited in use
🔹 Long-Term Requirements
- Think about future mobility changes
- A solution should offer safety and independence for years
A professional mobility assessment helps match needs with the right solution.
Final Verdict: Alternatives to Stairlifts for Very Narrow Stairs
Stairlifts are not always the only answer — especially when stair width and safety clearance aren’t suitable.
Alternatives like wheelchair platform lifts, step lifts, home modifications, vertical lifts, and ramps offer safe access options for a wide range of situations. A professional survey is essential to identify the most practical and secure solution for narrow stairs.
