Stairlift

Stairlifts are motorized seating devices installed along staircases to help individuals with mobility challenges navigate between floors safely and comfortably. They provide an affordable, space-efficient accessibility solution for homes and commercial buildings with multiple levels. Stairlifts are ideal for elderly individuals, people with disabilities, or anyone who finds stair climbing difficult.

Quick verdict

Is this the right choice for your building?

Existing homes, villas and small buildings with a usable staircase

Choose it if

  • A full lift shaft is impractical or too expensive
  • The user can transfer safely from a chair to the seat
  • The staircase is structurally suitable and has clear width

Think twice if

  • The user needs a wheelchair to remain seated during travel
  • The staircase is too narrow, steep or structurally weak
  • Multiple users need independent, unattended access on different floors

01

What a stairlift does

A stairlift is a chair or platform that travels along a rail fixed to the staircase. Most home stairlifts use a battery-powered drive, so they can continue to work during a power failure and can be parked out of the way when not in use.

It is not a substitute for a passenger lift. The user must be able to sit down, fasten the seat belt and transfer safely at the top and bottom. A stairlift is best for a single user or a small number of users with similar needs.

02

Straight versus curved stairs

A straight stairlift uses a simple rail and is usually faster and less expensive to install. A curved stairlift needs a custom rail that follows landings and turns, which takes longer to survey and manufacture.

Measure the staircase width, headroom, landing space and the position of doors at the top and bottom. A folded stairlift still occupies some space, so check that the hallway remains usable for other people.

  • Staircase width and clear passage when folded
  • Landing space at the top and bottom
  • Door swing and obstruction points
  • Structural fixing method for the rail

03

Safety features

A stairlift should have a seat belt, swivel seat, pressure-sensitive edges, a key switch, an emergency stop and obstruction detection. Battery-powered units should charge at a parking point at the top or bottom of the stairs.

Confirm the user can operate the controls comfortably and can get in and out without assistance. If the user's mobility changes, a home lift may become the safer long-term choice.

04

Installation and maintenance

Installation is much less disruptive than building a lift shaft, but the rail fixings must be secure and the staircase structure checked. The installer should demonstrate the controls, charging, emergency lowering and daily checks.

Service the battery, rail, rollers, seat and safety edges regularly. Keep the rail clear of dust and obstacles, and do not exceed the rated user weight.

Balance

Advantages and trade-offs

Advantages

  • Usually faster and less disruptive than building a lift shaft
  • Works with an existing staircase
  • Battery operation keeps working during a power cut
  • Can be folded away when not in use
  • Lower cost than a home lift in many homes

Trade-offs

  • Only one person travels at a time
  • Requires safe transfer from a chair
  • The rail and folded chair still take up stair width
  • Curved rails are custom-made and slower to supply

Before you order

Site checklist

01Check stair width, landings and door swings
02Confirm the user's ability to transfer safely
03Measure the staircase for a straight or curved rail
04Confirm a charging point and parking position
05Check the structural fixing and wall condition
06Agree the service and battery-replacement plan

Questions

Frequently asked questions

Does a stairlift work during a power cut?

Most home stairlifts run on batteries that are charged from the mains, so they can complete a trip during a power failure. Confirm the battery condition and charging procedure with the installer.

Can a stairlift be installed on a narrow staircase?

Sometimes. The folded chair and rail need to leave enough clear width for other users. A site survey will confirm whether the staircase can take a stairlift safely.

Can a wheelchair user use a stairlift?

A standard seated stairlift requires the user to transfer from the wheelchair. A platform lift or home lift is usually more appropriate for someone who needs to remain in a wheelchair.

How long does installation take?

A straight stairlift can often be installed in a day. A curved rail must be measured, manufactured and fitted, so it usually takes longer.
