Can a Stairlift Be Fitted to Any Staircase?

Most staircases can accommodate a stairlift, but not every staircase will suit every model.

Straight stairs are usually the simplest. Curved, narrow, spiral and outdoor stairs can also be suitable, but they need the right type of lift and a proper survey first.

At Stairlift Solutions, we look at the full staircase rather than one measurement. The width, angle, bends, landings, doorways and the person using the lift all matter.

How Do You Know If a Stairlift Will Fit?

The width of the stairs is only part of it.

During a free home survey, we check:

The overall shape of the staircase
The narrowest points
The gradient
Bends and landings
Headroom
Doorways or other obstructions
Space at the top and bottom
The user’s height, weight and mobility
Whether powered features would make the lift easier to use

We also check practical details such as where the stairlift will charge and whether a hinged rail is needed to keep a doorway or hallway clear.

The rail is fitted to the stair treads rather than the wall, so major structural work is rarely required.

Straight Staircases

A straight staircase is normally the easiest type to fit.

Stairlift Solutions offers several straight stairlifts, including the Brooks 130 Slimline, HomeGlide, Bespoke Synergy and Stannah Siena 600.

The Brooks 130 Slimline is particularly useful where space is limited. It measures around 310 mm wide when folded and is designed for narrow or compact stairs.

If there is a doorway at the bottom of the stairs, manual or powered hinged rail options can also be used on suitable models.

Curved, Spiral and Multi-Flight Staircases

A bend, half landing or change of direction does not rule out a stairlift.

Stairlift Solutions offers a range of curved stairlifts for more complicated layouts.

The Flow X is one of the most adaptable. Its Automatic Swivel and Levelling technology allows the chair to rotate while travelling, helping it deal with narrow stairs, steep gradients and tight bends. It can be installed on staircases as narrow as 610 mm and can also be configured for spiral staircases.

Other options include the Stannah Siena 260, Bespoke Infinity and Brooks 180. The Brooks 180 uses a modular rail system, so curved rails are not always made from scratch for each staircase.

What About Narrow Stairs?

Narrow stairs are one of the most common reasons people assume a stairlift will not fit.

Stairlift Solutions’ own guidance is that even staircases around 25 inches, or 64 cm, wide can sometimes accommodate a lift. The exact answer depends on the staircase and the person using it.

For particularly tight curved stairs, the Flow X can work from 610 mm depending on the configuration.

If a normal seated position takes up too much room, a perching model such as the Stannah Sadler 260 may also be worth considering.

Can a Stairlift Be Fitted Outside?

Yes, provided you use a model designed for outdoor use.

Stairlift Solutions supplies the Brooks outdoor stairlift for straight external staircases such as garden steps, porches, garages and entrances.

It uses components designed for outdoor conditions and is protected against rain, snow, heat and sunlight. A durable cover is also supplied for additional protection when the lift is not being used.

How Are Stairlifts Powered?

Modern stairlifts are usually battery operated and charge from a nearby mains supply.

For example, Brooks stairlifts automatically recharge when parked at the charging points. Because the lift itself runs from the batteries, it can continue operating during a temporary power cut.

There is no trailing power cable running up the staircase.

Can an Older or Awkward Staircase Take a Stairlift?

Often, yes.

Older houses can have narrow stairs, uneven layouts, sharp turns or unusual landings. Those are exactly the situations where choosing the right model becomes more important.

A curved model may be needed for bends, while a slimline, perching or swivel-while-moving stairlift can help where space is limited.

Stairlift Solutions has experience with staircases that other companies have previously ruled out.

One customer, Isobel Todd from Templepatrick, said:

“I phoned 3 other companies at the time and they all said my stairs were too narrow – but where others failed, your company succeeded and that’s it in a nutshell! … my life is a lot easier now and my husband also needs to use the stairlift too.”

That review is published on the Stairlift Solutions website.

How Much Does It Cost to Fit a Stairlift?

The staircase layout has a bigger impact on price than whether the stairs are unusual.

Straight stairlifts are generally cheaper because the rail is simpler. Curved stairlifts cost more because the rail has to follow bends, landings and changes of direction.

At Stairlift Solutions, reconditioned straight stairlifts start from £995 installed.

Reconditioned curved stairlifts are also available, currently starting from £3,495 installed with a new curved rail.

The final price depends on the model, rail length, staircase shape and any powered options required.

Is a Stairlift Worth Considering Before Moving Home?

If the stairs are the main reason you are considering moving, it is worth finding out whether they can be adapted first.

A stairlift is far less disruptive than moving house and can allow you to keep using bedrooms, bathrooms and other parts of the home that have become difficult to reach.

Stairlift Solutions has been supplying and fitting stairlifts across Northern Ireland for more than 25 years and offers new, reconditioned and rental options.

Find Out What Will Work on Your Staircase

You do not need to work out which stairlift you need before getting in touch.

The best place to start is with a free home survey. We can measure the staircase, look at how the lift will be used and explain which models are realistic for your home.

Whether your stairs are straight, curved, narrow, spiral or outdoors, there is a good chance there will be an option worth considering.
