The short answer
Fitting a straight stairlift usually takes around half a day, with a curved lift taking longer because the bespoke rail is more involved. Crucially, the rail fixes to the stair treads, not the wall, so it does not damage your plaster and works whether or not there is a wall alongside the stairs. The lift runs from a standard mains socket nearby and charges a battery, so it keeps working in a power cut. Most installations are tidy, same-day and need no building work. Stairlifts should then be serviced periodically — usually annually — to keep them safe and reliable.
A stairlift fitting is usually quicker and tidier than people expect. Here is what happens on the day, how the lift is fixed, and what keeps it running afterwards.

What happens on fitting day
- Time: a straight stairlift is commonly fitted in around half a day; a curved lift takes longer because the made-to-measure rail is more involved to install.
- Fixing: the rail bolts to the stair treads, not the wall, so it suits open-sided stairs and avoids drilling into plaster or brickwork.
- Power: the lift plugs into a nearby standard 13-amp socket and charges an onboard battery, so it still runs during a power cut.
- Tidy-up: most fittings need no building work and the staircase stays usable; the fitter will demonstrate the controls and safety features before leaving.
Servicing and aftercare
Once fitted, a stairlift should be serviced periodically — typically once a year — so the battery, safety sensors and moving parts stay reliable. Ask what the supplier's warranty and servicing arrangements are: how long the warranty runs, whether a service plan is included or extra, and how quickly call-outs are answered. Many suppliers also offer to remove the lift at the end of its use, which is worth confirming up front. Good aftercare is as much a part of the decision as the headline price.
| Stage | What's involved |
|---|---|
| Survey | measure the staircase, confirm straight or curved |
| Fitting | rail fixed to treads, lift mounted, controls demonstrated |
| Power | plugged into a nearby socket, battery charged |
| Aftercare | periodic servicing, warranty, optional removal |

Frequently asked questions
How long does it take to fit a stairlift?
A straight stairlift is usually fitted in around half a day. A curved stairlift takes longer because the rail is bespoke and more involved to install. Most fittings need no building work and leave the staircase usable the same day.
Does a stairlift fix to the wall?
No — the rail bolts to the stair treads, not the wall. That means it works on open-sided staircases and avoids drilling into plaster or brickwork. It does need a nearby mains socket to charge its battery.
Do stairlifts need servicing?
Yes. A stairlift should be serviced periodically, usually once a year, to keep the battery, sensors and moving parts safe and reliable. Check what warranty and servicing the supplier includes before you buy.
