Will a stairlift fit blog post
Discover if a stairlift fits your staircase with our comprehensive guide.

One of the most common questions we’re asked is: will a stairlift fit in my home?

In most cases, the answer is yes. The vast majority of staircases can accommodate a stairlift, including narrow, curved and more awkward layouts, as long as the right type of stairlift is chosen and it can be used safely.

From our experience visiting customers’ homes every day, people are often surprised by how many options there are. Even staircases that look difficult at first, we can usually find a stairlift that will fit.

Can Stairlifts Fit on Any Stairs?

In most installations, a stairlift will fit.

We regularly install stairlifts on:

  • Straight stairs
  • Curved stairs with corners, multiple turns, multi-flight staircases and even spiral stairs
  • Narrow staircases
  • Steep stairs
  • Open plan staircases
  • Outdoor staircases
  • Staircases made from different materials, including concrete and even marble

A situation we often see is someone assuming their stairs are “too awkward” — only to find there’s a perfectly suitable option once we measure it properly. Because we supply a wide range of stairlift models, where one type of stairlift won’t fit, there is often another that will.

The important thing to understand is that it’s not just about the stairs — it’s also about:

  • Your seated position
  • Knee clearance
  • Safe access at the top and bottom landings

That’s why a proper home survey is always the next step.

What Types of Stairs Can a Stairlift Fit?

Straight Stairs

Straight staircases are the simplest type of stairlift installation.

Straight stairlifts run on a single rail and are usually quicker to install. In many homes we survey, this is the most straightforward option.

Curved Stairs (Including Corners, Turns and Multiple Flights)

Yes — stairlifts can absolutely go around corners on curved staircases.

Curved stairlifts are designed to follow the exact shape of your staircase, whether that includes:

  • One bend
  • Multiple corners
  • Half landings
  • Full turns
  • Multi-flight staircases
  • Spiral stairs (which are treated as specialist curved designs)

From our experience, these types of staircases are often where people assume a stairlift won’t work — but in reality, they’re exactly what curved stairlifts are designed for.

Each rail is made to measure, so it fits your staircase precisely.

Narrow Stairs and Narrow Staircases

This is one of the biggest concerns people have.

From our experience, a straight stairlift will typically require around 660mm of width, whereas a curved stairlift can often be fitted on narrower staircases from around 610mm, depending on your measurements as well as the staircase.

Curved stairlifts are often the better option for tighter or narrower staircases, even if the stairs themselves are straight.

All stairlifts are designed to fold away when not in use. The seat, arms and footrest fold up, and the rail sits close to the stairs, which helps keep as much space clear as possible.

In some cases, where a straight stairlift won’t fit due to width restrictions, we can look at fitting a curved stairlift instead to make it work.

Steep Stairs

Steep stairs are not usually a problem, and are often one of the main reasons people look into a stairlift.

However, every stairlift operates within a minimum and maximum angle. The rail must sit within these tolerances for the lift to work safely.

In most UK homes, staircases fall within these limits, so steep stairs can usually still be fitted with a suitable stairlift.

Open Plan and Open Tread Stairs

Yes — stairlifts can be fitted to open plan and open-tread stairs.

If your staircase is open plan and does not have a bannister, we would strongly recommend having one fitted for safety reasons. This can either be arranged as part of the work or organised separately.

For open-tread staircases, a stairlift can usually be fitted without needing to fill the treads in. The rail is fixed directly to the stair treads themselves. We typically use shorter fixings so they do not come through the underside of the steps.

During a survey, we assess the safest and most suitable way to install the lift based on your staircase.

Outdoor Staircases

There are also outdoor stairlifts available.

These are built to withstand weather conditions and can be installed on external steps leading to a property or garden. Both straight and curved outdoor stairlifts are available, depending on the type of staircase.

How Much Space Does a Stairlift Need?

This is one of the most important parts of the decision.

A stairlift doesn’t just need to fit the staircase, it needs to work safely and comfortably for you.

As a guide:

  • Straight stairlifts typically require around 660mm of staircase width
  • Curved stairlifts can often fit on narrower staircases from around 610mm

However, width alone doesn’t tell the full story.

When we carry out a survey, we also look at:

  • Your seated position on the stairlift
  • Knee clearance past the wall or bannister
  • Space to get on and off safely at the top and bottom landings
  • The position of the footrest when travelling and parked

A situation we often see is a staircase that technically has enough width, but wouldn’t be safe because the user’s knees would be obstructed or there isn’t enough room to get on or off properly.

This is why a proper survey matters. It ensures the stairlift isn’t just fitted, but is safe, comfortable and practical to use every day.

How Stairlift Installation Actually Works

One of the biggest misconceptions is how stairlifts are fitted.

Stairlifts are not fixed to the wall.

Instead, the rail is attached directly to the steps, which means:

  • No need for a load-bearing wall
  • No redecoration required after installation
  • Suitable for most types of staircase, depending on the stairlift model used

The stairlift installation process typically involves:

  1. Measuring your staircase and requirements
  2. Manufacturing (for curved stairlifts)
  3. Installing the rail and lift
  4. Testing and demonstrating how to use it safely

In most installations, fitting a stairlift is straightforward and completed within a few hours.

What If a Stairlift Won’t Fit? (Rare, But Important)

Most staircases can accommodate a stairlift, but there are a small number of situations where it may not be suitable.

This usually comes down to:

  • Very narrow stairs combined with limited mobility or larger seating requirements
  • Restricted space at the top or bottom of the stairs, making it unsafe to get on or off
  • Situations where knee clearance or seating position would make the lift uncomfortable or unsafe to use

These cases are uncommon, but they highlight why a proper survey is important. It’s not just about whether a stairlift can be installed — it’s about whether it can be used safely and comfortably.

If a stairlift genuinely isn’t suitable, there are still other options available.

In these situations, we would normally look at:

These can provide safe access between floors without relying on the staircase itself.

The important thing is that there is almost always a solution, it just depends on finding the right one for your home and your needs.

“Another Company Said It Won’t Fit” — What This Really Means

Sometimes when a company says a stairlift won’t fit, what they really mean is that the specific model they supply isn’t suitable.

Different stairlifts are designed in different ways, and some are better suited to narrow or more complex staircases than others.

From our experience, having access to a range of stairlift models often makes the difference. Where one option doesn’t work, another often will.

That’s why it’s always worth getting a second opinion before ruling a stairlift out completely.ays worth getting a second opinion.

Final Thoughts

Most people wait longer than they should before looking into a stairlift.

Over the years, we’ve lost count of how many customers have said:
“I wish I’d done this sooner.”

If the stairs are starting to feel difficult or unsafe, it’s worth finding out what your options are, even if it’s just for peace of mind.

Common Questions About Stairlift Fitting

Do stairlifts need a load-bearing wall?

No — stairlifts are fixed to the stairs, not the wall.

Can a stairlift be fitted if there’s a radiator in the way?

Yes, but the radiator may need to be moved or replaced.

We would usually need the radiator to be replaced with a smaller one or moved along the wall if space allows.

We need clear space for the stairlift to park safely at the top or bottom of the stairs. The rail cannot be shortened to avoid an obstacle, as this would make it unsafe to get on or off the lift.

Can a stairlift be fitted in a listed building?

It depends on the grade of listing and the specific property.

You would need to check with your local authority to confirm whether permission is required. In most cases, a stairlift installation involves only minor fixings into the stair treads, rather than major alterations to the building.

Are stairlifts electric or battery operated?

All stairlifts are battery powered, but they charge from a standard mains power socket.

We can arrange for a suitable power point to be installed nearby if needed. This is usually positioned near the top of the stairs (around 600mm away) so the chair can park and swivel safely without trailing cables and conform to safety standards.
