If your staircase has any kind of bend, turn, or intermediate landing, you'll need a curved stairlift. These are custom-built to match the exact shape of your staircase, which is why they cost significantly more than straight models — and why getting the survey right is critical.

This guide covers pricing, what makes curved stairlifts different, which brands handle curves best, and what the installation process involves. All data verified as of April 2026.

What Is a Curved Stairlift?

A curved stairlift uses a rail that's custom-manufactured to follow the exact path of your staircase — including bends, turns, intermediate landings, and changes in gradient. Unlike straight rails (which are standard lengths cut to fit), every curved rail is a bespoke piece of engineering.

You need a curved stairlift if your staircase has any of the following:

  • A 90-degree turn (L-shaped staircase)
  • A 180-degree turn (U-shaped or dog-leg staircase)
  • An intermediate landing or half-landing
  • Any curve or bend, even a slight one
  • A spiral or helical staircase

If you're unsure whether your staircase counts as straight or curved, a stairlift company will confirm during the free home survey.

Curved Stairlift Prices

Configuration Price Range Typical Average
Standard curved (single bend) £3,800–£8,000 £5,500
Complex custom (multiple turns) £8,000–£12,000 Varies widely
Reconditioned curved £1,395–£4,475 £2,935
Rental (annual cost) £1,340–£2,240/yr £1,790/yr

Why Are Curved Stairlifts So Expensive?

The cost difference isn't profit gouging — it reflects genuine manufacturing complexity:

  • Custom rail manufacturing: Each rail is precision-engineered to your staircase measurements. There's no "standard" curved rail — every one is unique.
  • Precision survey: The home survey for a curved stairlift is more detailed. Measurements must be exact because the rail cannot be adjusted once manufactured.
  • Manufacturing time: 2–4 weeks of bespoke production compared to cutting a standard rail to length.
  • Complex installation: Fitting a curved rail takes 4–8 hours compared to 2–4 hours for straight.
  • No resale/reuse: A curved rail is made for one specific staircase. It has virtually no secondhand value, unlike straight rails that can be reused.

What Drives the Price Up?

  • Number of turns: Each turn adds manufacturing complexity
  • Staircase length: More rail = more material and engineering
  • Tight turns: Narrow staircases with tight bends require more precise engineering
  • Start/end position: If the rail needs to extend around a corner at top or bottom for safe boarding
  • Features: Powered swivel, powered folding rail, heavy-duty capacity

Which Brand for Curved Stairlifts?

Curved stairlifts are where the brand choice matters most, because the quality of the survey and rail manufacturing directly affects the result:

  • Stannah (8.4/10): The most experienced curved stairlift installer in the UK. If your staircase is complex, Stannah's survey expertise is worth the premium. Their curved rail manufacturing is regarded as the industry benchmark.
  • Handicare (8.1/10): The 1100 slim rail model is particularly valuable for curved staircases where width is tight. Their curved rail engineering is strong, and pricing is typically below Stannah.
  • Acorn (7.8/10): Offers curved models at competitive prices. More limited curved range than Stannah, but adequate for straightforward curved staircases.

For complex curved staircases (multiple turns, spiral, or unusual configurations), Stannah is our recommendation. The survey accuracy is critical, and a poorly measured curved rail is an expensive mistake that cannot be fixed on site.

Installation Process

  1. Home survey (free): A surveyor visits to take detailed measurements of your staircase. This is more thorough than for a straight stairlift — expect 45–90 minutes. Some companies use digital/laser measuring tools for maximum accuracy.
  2. Design and manufacture: Your rail is custom-designed and manufactured. This typically takes 2–4 weeks. Some companies offer expedited production for urgent cases.
  3. Installation: Takes 4–8 hours. The rail is fixed to the stair treads, not the wall. The stairlift is fitted to the rail and tested thoroughly.
  4. Handover: Full demonstration and training on operation, safety features, and what to do if something goes wrong.

Timeline

Plan for 2–4 weeks from survey to installation. This is significantly longer than straight stairlifts (which can sometimes be installed within days). If you need a stairlift urgently for a curved staircase, mention this at the survey stage — some companies can expedite manufacturing.

Reconditioned Curved Stairlifts

Reconditioned curved stairlifts are available but less common than reconditioned straight models. Because every curved rail is bespoke, a reconditioned curved stairlift can only be reused if your staircase happens to match the original staircase almost exactly — which is rare.

In practice, "reconditioned curved" usually means a refurbished stairlift unit on a new custom rail. The savings compared to fully new are more modest than for straight models.

Rental for Curved Stairlifts

Curved stairlift rental is available but more expensive than straight rental. Expect approximately £20 per week plus an installation fee of £950 or more (compared to £10–15/week and £300+ for straight). The higher installation fee reflects the custom rail cost.

Rental can still make sense for temporary needs (post-surgery recovery, for example), but the economics are less favourable than for straight stairlifts.

VAT and Grants

The same VAT relief applies to curved stairlifts as straight:

  • Disabled users: 0% VAT (saving 20%). Self-declaration, no medical proof needed.
  • Users aged 60+: 5% VAT on supply and installation (saving 15%).

Given the higher cost of curved stairlifts, VAT relief saves even more in absolute terms. On a £5,500 curved stairlift, 0% VAT saves approximately £920 compared to the standard 20% rate.

The Disabled Facilities Grant (up to £30,000 in England) can cover curved stairlift costs. Given that curved stairlifts cost more, the grant may cover a larger proportion of your needs. See our buying guide for full grant details by region.

Frequently Asked Questions

How much does a curved stairlift cost?

A new curved stairlift costs £3,800–£8,000 for standard configurations, averaging around £5,500 installed. Complex custom installations (multiple turns, unusual staircase shapes) can reach £8,000–£12,000. Reconditioned curved models are available but less common.

Why are curved stairlifts so much more expensive than straight?

Every curved stairlift rail must be custom-manufactured to match your exact staircase dimensions. This requires a precision survey, bespoke manufacturing (typically 2–4 weeks), and more complex installation. Straight stairlifts use standard off-the-shelf rails that are simply cut to length.

How long does it take to get a curved stairlift installed?

Typically 2–4 weeks from survey to installation. The rail needs to be custom-manufactured to fit your staircase. Installation itself takes 4–8 hours — longer than a straight stairlift because of the custom rail and more complex fitting.

Can any stairlift company fit a curved rail?

All three major UK brands (Stannah, Acorn, Handicare) offer curved stairlifts. Stannah has the most experience with complex curved installations. The quality of the survey and manufacturing is critical — poorly measured curved rails cannot be adjusted on site.
