Straight vs Curved Stairlifts
A clear, plain-English comparison of straight and curved stairlifts — written by the local engineers who fit them every day across Plymouth, Devon and East Cornwall. Understand the differences, what each suits, what they cost and how to choose with confidence.
Quick answer
- Straight stairlifts are designed for staircases without bends — a single continuous rail in a straight line.
- Curved stairlifts are custom-built for staircases with bends, corners, winders, half-landings or intermediate landings.
- If your stairs turn even slightly, you need a curved lift — a straight rail cannot be bent around a corner.

What is a straight stairlift?
A straight stairlift runs along a single straight rail fixed to the treads of a staircase. The seat travels smoothly up and down on a rack-and-pinion drive, powered by long-life batteries that charge when the lift is parked.
Because the rail is a standard length cut to size, straight stairlifts are the fastest and most affordable type of lift to install — most fits are completed in a single morning, often within days of the home survey, so it's worth getting a survey booked early if you have a discharge date or recovery deadline.
Where it's suitable
Any staircase that runs in a single straight line from bottom to top with no bends, winders or landings.
Advantages
- Lowest cost — often half the price of curved
- Fastest installation (2–4 hours)
- Often available the same week
- models available
- Short-term rental from around £25/week
Limitations
- Will not fit a staircase with any bend
- Cannot follow half-landings or winders
What is a curved stairlift?
A curved stairlift uses a bespoke rail manufactured for one specific staircase. After your survey, the rail is CAD-designed using precise measurements of every step, bend and landing, then manufactured and finished before installation.
Because no two staircases in the UK are identical — even in identical houses — every curved rail is unique. This is why curved lifts cost more and take longer to deliver, but it's also why they fit so beautifully and run so smoothly.
Where it's suitable
Any staircase with a bend, winder, half-landing, intermediate landing or split level — including period properties, narrow Victorian terraces and modern open-plan homes.
Advantages
- Fits virtually any staircase
- Bespoke rail — perfect fit and finish
- Smooth, level travel around corners
- Handles multiple bends and landings
- Same 2-year warranty as new straight lifts
Limitations
- Higher cost than straight equivalents
- 2–4 week lead time for rail manufacture
- Rarely available

Which stairlift is right for you?
The honest answer is: it depends on your staircase, not your preference. Here are the most common situations we see across Plymouth and the South West.
Older couple in a 1960s semi
Straight staircase, no landings — a straight stairlift fitted in a morning is almost always the right choice, and often for best value.
Recovering from hip or knee surgery
If the staircase is straight, a short-term straight rental from around £25 per week is ideal. If the stairs turn, a curved rental or a bought curved lift may be the better answer.
Listed building or period cottage
Bespoke curved rails preserve the staircase and avoid intrusive structural work — perfect for properties where character matters.
Narrow Victorian terrace
Slimline curved lifts with folding seats and hinged rails sit tight to the wall and keep doorways and hallways clear.
Split-level or 1970s bungalow
A short curved rail spanning one or two steps and a landing is usually the safest, most elegant solution.
Large family home, two storeys
If there is even one turn, a curved lift is essential. The investment pays back over 10–15 years of independent living.
Cost comparison
In general, a new straight stairlift in Plymouth costs around £1,800–£3,500 fitted, while a new curved stairlift costs £3,500–£6,500+ fitted. The difference reflects the bespoke rail design, manufacture and longer installation.
Straight stairlifts start from around £1,200, making them excellent value for simple staircases. Curved stairlifts are rarely because every rail is unique to its original home.
VAT relief for chronically sick or disabled users and Disabled Facilities Grants of up to £30,000 can significantly reduce the real cost of either type.

Common myths — busted
"Curved stairlifts are always too expensive."
Curved lifts cost more than straight ones — but funding, VAT relief and grants often bring the real price down significantly. Many families pay far less than they expected.
"A straight stairlift can be made to fit around a bend."
No — a straight rail is one continuous piece. Any staircase with a bend, half-landing or split level needs a bespoke curved rail.
"Installation takes weeks of disruption."
A straight lift is fitted in a morning. A curved lift takes one visit of 4–8 hours once the bespoke rail has been manufactured.
"Stairlifts damage your stairs."
Rails screw into the treads, not the walls. When removed, the small holes are easily filled — no structural damage at all.
"You can't use the stairs once a stairlift is fitted."
Both straight and curved rails sit tight to one side of the staircase. Other family members can use the stairs normally.
"Curved stairlifts are unreliable because they're complex."
Modern curved lifts are extremely reliable. The bespoke part is the rail — the motor and components are the same proven technology as straight lifts.
Real customer stories
Mrs P, Plympton
Mrs P needed a reliable solution after a fall. Her staircase was a straight run with no bends, so we fitted a straight stairlifts the following week — surveyed Monday, fitted Friday. Two-year warranty included, well within her budget.
Mr & Mrs B, Plymstock
A 1930s home with a 90° bend and a small half-landing. We CAD-designed a bespoke rail to follow the original staircase exactly. Manufacture took three weeks, installation took one afternoon and the lift has run faultlessly since.
