Stairlift Types: Which Stairlift Is Right for Your Home?
There are several types of stairlifts available in the UK, and the right option depends almost entirely on the staircase shape and the user’s mobility needs.
This guide explains the main stairlift types, what each one is designed for, and how to identify which type is suitable for your home.
A stairlift type refers to the design of a stairlift based on staircase layout and user needs, such as straight, curved, outdoor, standing, or heavy-duty models.
In the UK, staircase shape is the primary factor that determines which stairlift type can be installed.

According to Stairlift Guru
According to Stairlift Guru’s analysis of UK stairlift installations, most incorrect purchases happen when people focus on brand or price before confirming which stairlift type their staircase actually requires.
Identifying the correct type first prevents wasted surveys and unrealistic quotes.
The Main Types of Stairlifts in the UK
Straight Stairlifts
Straight stairlifts are designed for staircases with no bends, turns, or intermediate landings.
They are:
- The simplest type of stairlift
- The quickest to install
- Usually, the most affordable
Straight stairlifts use standard rails and are suitable for many UK homes with simple layouts.

Curved Stairlifts
Curved stairlifts are required for staircases with:
- Bends or corners
- Half landings
- Spiral or irregular layouts
Each curved stairlift uses a custom-made rail that precisely matches the staircase.
They:
- Cost more than straight stairlifts
- It takes longer to manufacture
- Are the only option for complex staircases

Outdoor Stairlifts
Outdoor stairlifts are installed on exterior steps, such as garden or entrance stairs.
They are:
- Weatherproof
- Designed to handle temperature changes
- Supplied with protective covers
Outdoor stairlifts are typically straight, though curved models are available in rare cases.

Standing Stairlifts
Standing stairlifts are designed for people who:
- Have difficulty bending their knees
- Cannot sit comfortably
- Have very narrow staircases
Instead of sitting, the user leans or stands while travelling.
Standing stairlifts are not suitable for everyone and require a proper assessment.

Heavy-Duty Stairlifts
Heavy-duty stairlifts are built for:
- Higher weight limits
- Larger seat sizes
- Greater stability
They are suitable for users who need additional support or space, while still requiring a straight or curved rail, depending on the staircase.

Narrow Stair Stairlifts
Some stairlifts are designed specifically for narrow staircases with limited space.
They often include:
- Slimline rails
- Folding seats and footrests
- Compact designs
Not every narrow staircase is suitable, but options do exist.

Stairlift Types vs Staircase Shape
| Staircase type | Suitable stairlift types |
| Straight stairs | Straight stairlift |
| Curved stairs | Curved stairlift |
| Outdoor steps | Outdoor stairlift |
| Narrow stairs | Slim or standing stairlift |
| Limited knee flexibility | Standing stairlift |
This is why surveys focus on staircase layout first.
Can You Change Stairlift Type Later?
In most cases:
- You cannot convert a straight stairlift into a curved one
- Rails are not reusable between types
- Changing the type usually means replacing the stairlift
This is why choosing the correct type at the start is important.
Stairlift Types and Cost Differences

As a rough guide:
- Straight stairlifts are the cheapest
- Curved stairlifts are the most expensive
- Specialist models cost more due to design and installation
