One of the most common questions people ask when considering a stairlift is: “What’s the difference in cost between a straight stairlift and a curved stairlift?”
In the UK, the price difference between straight and curved stairlifts can be significant. This guide explains how much each type typically costs, why curved stairlifts are more expensive, and what factors affect the final price.
Is a Straight Stairlift Cheaper Than a Curved Stairlift?
Yes. Straight stairlifts are always cheaper than curved stairlifts.
This is because straight stairlifts:
- Use a standard, non-custom rail
- Require less manufacturing time
- Are quicker and simpler to install
Curved stairlifts, on the other hand, require a bespoke rail designed specifically for the shape of your staircase, which increases both production and installation costs.
Straight Stairlift Cost in the UK
Straight stairlifts are the most affordable stairlift option available in the UK.
The cost of a straight stairlift depends on:
- Length of the staircase
- Seat type and comfort options
- Powered or manual swivel seat
- Folding rail or hinged rail options
- New or reconditioned model
Because the rail is standard, pricing is more predictable and generally much lower than for curved stairlifts.

Curved Stairlift Cost in the UK
Curved stairlifts cost more than straight stairlifts due to their custom design.
The price of a curved stairlift depends on:
- Number of bends or turns
- Length of the staircase
- Number of landings
- Complexity of the staircase layout
- Seat type and optional features
Each curved rail is manufactured to match the staircase exactly, which means no two curved stairlifts cost the same. A home survey is required to provide an accurate price.

Why Curved Stairlifts Cost More Than Straight Stairlifts
The main reason curved stairlifts cost more is rail construction.
Straight stairlifts:
- Use pre-engineered straight rails
- Require minimal customisation
- Can be installed quickly
Curved stairlifts:
- Require detailed staircase measurements
- Use a custom-made rail
- Take longer to manufacture
- Involve more complex installation
Even a single bend in the staircase means a curved rail is required, which increases the overall cost.
Installation Costs: Straight vs Curved Stairlifts
Installation costs also differ between the two types.
- Straight stairlifts are usually installed in a single day, often within a few hours.
- Curved stairlifts take longer overall due to rail manufacturing, although installation is still completed efficiently once the rail is ready.
Both types are installed by fixing the rail to the stair treads, not the wall, and do not usually require structural changes.
Can VAT Relief Reduce Stairlift Costs in the UK?
Many customers in the UK may qualify for VAT relief on stairlifts, which can reduce the overall cost.
VAT relief may apply if:
- The stairlift is installed for mobility or medical reasons
- The user has a long-term illness or disability
VAT relief can apply to both straight and curved stairlifts, subject to eligibility.
New vs Reconditioned Stairlift Costs
Another factor that affects price is whether the stairlift is new or reconditioned.
- Straight stairlifts are commonly available as reconditioned models, which can reduce costs further.
- Curved stairlifts are less commonly reconditioned because rails are custom-made, although refurbished units may sometimes be available.
Reconditioned stairlifts are fully tested and serviced before installation.
Which Stairlift Offers Better Value for Money?
In terms of value:
- A straight stairlift offers the best value if your staircase is straight, as it provides reliable mobility support at the lowest cost.
- A curved stairlift offers value only when it is required — that is, when the staircase includes bends or landings.
Choosing a curved stairlift when a straight stairlift would be suitable results in unnecessary expense.
Straight vs Curved Stairlift Cost Comparison
| Cost Factor | Straight Stairlift | Curved Stairlift |
|---|---|---|
| Rail type | Standard straight rail | Custom-made curved rail |
| Manufacturing | Standard | Bespoke |
| Installation time | Faster | Longer |
| Overall cost | Lower | Higher |
| Reconditioned options | Widely available | Limited |
Why a Staircase Assessment Is Important
It’s common for homeowners to assume they need a curved stairlift based on appearance alone. In reality, many staircases are straight and suitable for a more affordable straight stairlift.
A professional assessment ensures:
- The correct stairlift type is recommended
- Costs are kept as low as possible
- Installation is safe and appropriate
Cost FAQs
Is a Straight Stairlift Cheaper…
Yes. Straight stairlifts are cheaper than curved stairlifts because they use standard rails instead of custom-made rails.
Why is a curved stairlift more expensive?
Because the rail is custom-made to match the staircase, increasing manufacturing and installation costs.
Is a straight stairlift always cheaper?
Yes. Straight stairlifts are always cheaper than curved stairlifts when comparing equivalent features.
Can I save money by choosing the wrong stairlift?
No. Installing the wrong type is unsafe and not possible. The staircase determines the stairlift type.
Does staircase width affect the price?
Width can affect model choice, but direction and layout have a much bigger impact on cost.
Next Steps
If your staircase is straight, a straight stairlift is the most affordable and practical solution. If your staircase includes bends or landings, a curved stairlift will be required despite the higher cost.
A home survey will confirm the correct option and provide accurate pricing.
