Stair Shapes 101: What You Need to Know

Before we talk about stairlifts, we need to talk about stairs.

Your staircase shape plays a big role in determining the type of stairlift you’ll need and how easy or complicated the installation might be.

Let’s take a look at the most common types of staircases found in UK homes.

Staircase Type Description Stairlift Solution Can Fit Stairlift?
Straight stairs No bends or landings. Goes straight up in one line. Straight stairlift (standard model) Yes, very easily
Curved stairs Includes bends, turns, or spiral sections Custom curved stairlift Yes, but custom
Narrow stairs Less than 70cm wide Slimline or perch stairlift Yes, with care
Stairs with landings Has one or more flat areas or changes in direction Curved or twin straight stairlifts Yes, with planning
Outdoor steps Steps outside the property, often at entrances Weatherproof outdoor stairlift Yes, specialised

As you can see, whether your stairs are straight, curved, narrow or steep, there’s usually a solution.

Can Stairlifts Be Fitted to Any Stairs?

The Honest Answer: Almost Always

In over 95% of homes, stairlifts can be installed successfully. Thanks to advancements in engineering and customisation, stairlift companies can now design rails and chairs to fit just about any staircase.

That said, there are a few things to keep in mind.

A Few Handy Pointers

1. Stair Width

  • Most stairlifts require at least 700mm (27.5 inches) of stair width.
  • If your stairs are narrower, a perch stairlift (where you stand or perch rather than sit) may be the ideal solution.

2. Weight Capacity

  • Standard stairlifts usually carry up to 120kg (19 stone).
  • Heavy-duty models are available for higher weight limits, often up to 160kg (25 stone).

3. Headroom

  • If your stairs pass under a low ceiling or beam, some compact models with lower seat heights can be installed.

4. Power and Access

  • A nearby standard plug socket is all that’s needed.
  • Stairlifts run on battery power, charging when parked at the top or bottom.

Straight vs Curved Stairlifts Explained

Straight vs curved stairlifts

Straight Stairlifts:

You’ll find straight staircases in most UK houses, and they’re often the easiest to fit with a stairlift.

  • What you need: A straight rail stairlift
  • Installation time: As little as a couple of hours
  • Reconditioned options available: Loads!
  • Cost: Cheapest type – especially if you go reconditioned

If you’ve got a straight staircase, you’re in luck. You can easily find reconditioned stairlifts that fit your setup, which means you’ll save money without compromising safety.

Curved Stairlifts:

Got a bend, a 90-degree turn, or a multi-floor staircase? You’ll need a curved stairlift.

  • What you need: A custom curved rail stairlift
  • Installation time: 1–2 days, typically
  • Reconditioned options available: Yes, but the rail is often made-to-measure
  • Cost: Higher due to bespoke rail

Here’s the thing: the stairlift itself can be reconditioned, but the rail usually needs to be custom-made to fit your staircase. This means the cost can be higher than with a straight stairlift, but it’s still cheaper than buying a brand-new unit.

How Different Staircases Affect Stairlift Installation Costs

Because staircases come in all shapes and sizes, stairlift options and costs will vary accordingly.

Here’s a typical price guide to help you plan:

Stair Type New Stairlift Price Reconditioned Price Installation Time
Straight £2,000 – £3,000 £1,000 – £1,800 1 – 2 hours
Curved £4,000 – £6,000+ £2,500 – £3,800+ 4 – 6 hours
Narrow/Compact Same as above, may need perch model Same as above Slightly longer
Outdoor £2,500 – £4,000 £1,800 – £3,000 2 – 3 hours

Note: These are average figures across the UK. At Reconditioned Stairlift Prices, we offer competitive pricing on reconditioned stairlifts, plus flexible financing through easy payment and rental options too.

How Stairlifts Adapt to Unusual Stair Designs

You might be thinking, “My stairs are a bit of an odd shape. Surely I’ll struggle to get a stairlift.”

You’d be surprised how often we hear this! Here's the truth:

  • Spiral staircases? Not a problem — curved stairlifts can be custom-made to follow the shape.
  • Half landings? These are very common, and stairlifts can curve around them easily.
  • Steps that change direction? Easily handled with a curved rail or linked straight lifts.
  • Very steep stairs? Stairlifts can be angled appropriately and safely.
  • Very narrow stairs? Slimline seats and foldable footrests can make it work.

So, unless your staircase is completely vertical (like a loft ladder!), chances are a stairlift can still be installed.

What About Stairlift Rails – Do They Fit Every Staircase?

This is where things get interesting.

There are two types of rails for stairlifts:

  • Standard straight rails – off-the-shelf and very affordable.
  • Custom curved rails – tailored to your specific staircase.

Straight rails: Reconditioned rails can usually be trimmed to fit your stairs perfectly.

Curved rails: These must be custom-built to the exact measurements of your stairs, but the stairlift seat and motor can still be reconditioned to save money.

Don’t worry – a stairlift installer will measure everything precisely during a free home visit.

Frequently Asked Questions - Can Stairlifts Be Fitted to Any Stairs?

Frequently Asked Questions

Can a stairlift be fitted on any type of staircase?

Yes! Stairlifts can be fitted to nearly all types of staircases, including straight, curved, narrow, and those with landings. Customisation options allow installers to adapt the rail to your staircase’s unique shape and size.

Do I need a special power supply for a stairlift?

No special wiring is required. Stairlifts run on rechargeable batteries charged via a standard household plug socket, usually placed near the top or bottom of the stairs.

Will installing a stairlift damage my stairs or walls?

No. Stairlift rails are fixed to the stair treads (the horizontal parts of the stairs), not the walls. This means minimal impact on your home’s structure and easier removal if needed.

What If There’s a Door at the Bottom or Top of My Stairs?

This is quite common in UK homes.
If a door opens onto the staircase, you might need a hinged rail or a retractable rail at the bottom.

  • Automatic hinged rails fold up when not in use
  • Manual hinged rails need to be lifted by hand

This adds a bit to the price, but it makes the stairlift safe and practical in tighter spaces.

Is There Enough Room on My Stairs for a Stairlift?

Another common concern – especially in narrow UK terraces – is space.
Most staircases only need around 700mm (27 inches) of width for a standard seated stairlift. If that’s tight, there are solutions:

  • Perch stairlifts: Designed for users who have trouble bending their knees
  • Compact models: Take up less space when folded

And yes, these are available reconditioned too!
