How long does a stairlift last?
There is no single number. How often it is used, who rides it, the stairs, and whether anyone services it all change the answer.
Stannah's aftercare page says stairlifts generally last around ten years, and that this varies with use. Their Ireland page puts the average at 7 to 10 years, with regular maintenance stretching that. Lifeway Mobility, a US dealer, calls 10 years a safe assumption, not a promise. Stannah's US cost page also cites a 10 to 20 year lifespan in a cost comparison. Those are published ranges, not a clock on your house.
Need A Stairlift does not sell stairlifts. We collect competing installer quotes for you, free. Warranty length and who services the lift belong on that comparison.
What wears out first
The rail and motor are built to last. The batteries are not.
Stannah's US buyer's guide says batteries last between 1 and 5 years. That depends on use and whether the chair is left off the charger. Lifeway's maintenance list is similar: replace batteries every 1 to 3 years with heavy use, or 3 to 5 years with light use. Bruno will not pick a number. Their FAQ says some batteries last a decade and some fail in the first year if the charger is the problem.
Park the chair on its charging point. Stannah says leaving it off charge shortens battery life. Bruno indoor lifts charge wherever they stop on the rail. Outdoor and some curved models charge when parked at the top or bottom.
During a power cut, Stannah says a full charge is good for about 15 to 20 round trips. Bruno's 2026 guide puts indoor straight lifts at about 10 to 15 round trips, depending on stair length, angle, and rider weight.
Warranties are not the same as lifespan
A warranty tells you who pays if a part fails. It is not how long the chair will run.
Bruno indoor lifts carry a limited lifetime warranty on the motor, gearbox, and static rail for the original owner, if a Bruno dealer installed it. Other parts are two years. Labor is 30 days. Outdoor Bruno lifts are five years on those major parts.
Stannah, when you buy direct, offers a lifetime warranty on the carriage motor gearbox for a new lift, and 10 years on a reconditioned one. Their cost page also lists 2-year parts and 1-year labor on a new unit. If you buy from a distributor, they tell you to ask that company.
Savaria's Stairfriend 23 brochure lists 36 months on parts.
Ask each quote which parts last past the labor window, and who you call after that. Brand differences beyond that are in best stairlift brands.
What keeps a lift going
Stannah advises a service every 12 months. Bruno says most manufacturers recommend annual work: clean and relubricate the gear rack, check battery voltage, and inspect the roller wheels for flat spots.
Our FAQ is shorter. Keep the rail clean, keep the stairs clear, and expect the batteries to need replacing.
Straight indoor lifts tend to last longer than outdoor ones. Stannah's Ireland page notes that weather hits outdoor chairs even with a cover. A steep or curved rail can also add stress.
Stay inside the published weight rating. Exceeding it overburdens the motor. More on that in what's the weight limit.
What to check on the quotes
- Expected service life for that model, in writing if they will give it
- Battery replacement: who does it, and about how often
- Annual service cost after the warranty
- Motor and gearbox coverage vs everything else
- Who actually comes out if it stops
A national brand can still quote $7,000 or more for a straight lift that a local installer prices for much less. Longevity is one column. Price and who services it are the others.
