Reviewed by Lukasz Zelezny for the Companion Stairlifts range. The fault behaviour of a Companion Stairlifts stairlift is much like any other: beeps at the charging point, a seat-swivel interlock that must be satisfied, obstruction sensors that stop travel, and batteries with a finite life. Each is explained here as it applies to Companion Stairlifts, written for owners, with the engineer hand-over point clearly marked.
Quick Diagnosis
Answer up to three questions. We'll point you at the most likely Companion Stairlifts fault on this page — full detail stays visible below either way.
Common Companion Stairlifts Faults
The companion stairlifts lift problems reported most often to UK service desks — expanded in the order owners typically encounter them. Several are resolved by routine Companion Stairlifts maintenance rather than a call-out, and the rest are far quicker to fix when you can describe the symptom precisely to whoever handles your Companion Stairlifts repair.
Companion Stairlifts stairlift seat swivel not locked
Owner-safe checkThe Companion Stairlifts chair will not travel because the seat isn't sensing as locked in the forward position.
This symptom accounts for a steady share of the Companion Stairlifts repair enquiries we see each month. Every UK stairlift, Companion Stairlifts included.
Interlocks the seat swivel: the chair will not travel unless the seat is locked either facing forward for travel or rotated to the safe dismount angle for exit.
On manually swivelled Companion Stairlifts chairs, press down firmly on the seat cushion and rotate it through the click. You should feel a positive lock. On powered swivel Companion Stairlifts models.
The swivel motor runs for a couple of seconds and only reports the seat as locked once the motion is complete. Pressing the joystick during the swivel cycle produces exactly this fault.
If the chair still refuses to travel with the seat visibly forward, the swivel micro-switch beneath the seat needs adjustment or replacement. This is a Companion Stairlifts engineer task rather than an owner adjustment.
A short entry in the Companion Stairlifts maintenance log now avoids any later doubt about whether the fault was reported before the next Companion Stairlifts servicing visit.
Companion Stairlifts stairlift battery not charging
Owner-safe checkThe Companion Stairlifts stairlift beeps a low-battery warning even after being left on charge overnight.
This is one of the most common reasons UK owners look up Companion Stairlifts troubleshooting in the first place. A Companion Stairlifts stairlift that won't take charge is a two-step check.
First, confirm the transformer plugged into the wall socket is live: most Companion Stairlifts chargers have a small LED that lights when mains is present. The socket itself must be switched on.
Second, confirm the chair is fully parked on a live charging strip — a few centimetres short of the park position and the chair will beep but not charge.
If both are correct and the Companion Stairlifts chair still won't hold charge, the internal 24V battery pack (two 12V sealed cells) is nearing end of life. Typical UK service life is 3–5 years.
Batteries at end of life still take charge but discharge in one or two trips. Whatever the outcome, note the date and the symptom in your Companion Stairlifts maintenance record.
A clear history makes the next Companion Stairlifts servicing visit quicker.
Companion Stairlifts stairlift stops mid-rail
Owner-safe checkThe Companion Stairlifts chair halts partway up or down the stairs and refuses to continue.
Of every Companion Stairlifts troubleshooting question sent to us. This symptom is among the most frequent.
A Companion Stairlifts stairlift stopping in the middle of a rail is almost always the obstruction sensors doing exactly what they are designed to do.
Every UK stairlift including Companion Stairlifts has bumper switches under the footplate and along the sides of the carriage.
The smallest snag — a slipper poking out of a stair-runner, a loose bit of stair carpet, a pet toy — will trigger a stop.
Walk the stair path from top to bottom and clear anything protruding into the travel line, wipe the underside of the footplate, then try the Companion Stairlifts chair again.
If it repeatedly stops in exactly the same place, note the position; that pinpoint is what a Companion Stairlifts service engineer needs to diagnose the fault on the first visit.
Write down what you saw and when. Regular Companion Stairlifts servicing catches most of these early, and good Companion Stairlifts maintenance notes shorten the engineer's diagnosis.
Companion Stairlifts stairlift key switch is in the wrong position
Owner-safe checkThe Companion Stairlifts chair is completely dead — no lights, no beep — and the key was moved.
Read this through before booking any Companion Stairlifts repair. The answer is often simpler than it looks. Every UK stairlift has a key isolator, usually on the arm of the chair.
Turning the key to the off position disables the Companion Stairlifts chair entirely. This is useful with young children in the house but frustrating when a carer arrives and can't find the key.
If a Companion Stairlifts stairlift shows no lights and makes no beep, the first thing to check is the key: turn it to the on position and try again.
Spares are always supplied on fitting for a Companion Stairlifts chair. Keep at least two somewhere every household member knows about.
If the key is really lost, Companion Stairlifts can supply a replacement identified by the number stamped on the barrel.
If it becomes a repeat event, treat it as a Companion Stairlifts servicing question rather than a one-off Companion Stairlifts repair; recurring symptoms usually trace back to a missed maintenance interval.
Companion Stairlifts stairlift remote control not working
Owner-safe checkThe wall-mounted Companion Stairlifts remote does not call the chair, but it works from the arm control.
Most people arriving at Companion Stairlifts troubleshooting pages describe the problem in roughly these words. Wall-mounted remotes on a Companion Stairlifts stairlift work on either infra-red line-of-sight or short-range radio.
If a call from the remote does not respond, but the chair works fine from the arm-mounted control. The fault is almost always in the remote itself.
Start with the remote batteries — most Companion Stairlifts remotes take a single 9V or two AAAs and a low remote battery will simply stop transmitting.
Beyond that, remotes for Companion Stairlifts chairs are a swap-in fob, so a lost, damaged, or de-paired remote can be replaced without opening the chair.
Never remove the arm covers to investigate a remote fault. The Companion Stairlifts chair is still fully usable from its own arm control while a replacement is sourced.
Keep the Companion Stairlifts maintenance paperwork with the lift. Whoever attends the Companion Stairlifts repair will want to see when the last service was done.
Companion Stairlifts stairlift obstruction sensors triggered
Owner-safe checkThe Companion Stairlifts chair reports an obstruction even when nothing visible is in the way.
Before you phone anyone about a Companion Stairlifts repair, work through the description below. If a Companion Stairlifts chair repeatedly reports obstruction with the stair-path clear, the sensors themselves are the suspect.
The bumper switches under the footplate and along the carriage of a Companion Stairlifts stairlift use small mechanical actuators; when they age they can become spongy and trip on nothing more than the Companion Stairlifts chair's own movement.
Wipe the underside of the footplate and the sides of the carriage.
Run the chair slowly through the point where it usually reports the obstruction, and note whether the fault repeats in exactly the same position.
That pattern is what tells the Companion Stairlifts service engineer whether the fault is a rug still in the way, a sensor drifting out of tolerance, or a bent actuator arm.
Faults in this family are largely prevented by keeping to the Companion Stairlifts servicing schedule, so check the date of your last Companion Stairlifts maintenance visit while the paperwork is out.
Companion Stairlifts repair
Most enquiries that reach us are described as a Companion Stairlifts repair, but roughly a third turn out to be a reset, a battery on charge, or a door edge that is not quite closing. Work through the checks above first and write down exactly what the stairlift does — the noise, the light, the floor it stops at. That note is what turns a vague call-out into a first-visit fix.
Anything behind a cover or panel, in the pit or shaft, or involving doors, gates and interlocks is engineer-only work. Your part of a Companion Stairlifts repair is to check and report: mains power on, isolator on, emergency stop out, nothing in the door threshold, and a written note of the fault code.
What Noise Is Your Companion Stairlifts Stairlift Making?
Lifts talk. Not eloquently — but a grind, a beep or an ominous silence each means something. Press play, compare, and pick the closest match.
Example sounds are synthesized approximations to help you compare — not recordings of Companion Stairlifts equipment.
Grinding — likely causes on a Companion Stairlifts stairlift
✅ Owner-safe check- Debris (carpet fibres, pet hair, small toys) fouling the rack or pinion
- Lack of lubrication on the rail after years of service
- A worn pinion gear or rack tooth reaching end of life
A grinding noise on a Companion Stairlifts stairlift almost always comes from the rack-and-pinion drive on the underside of the rail.
Owner scope stops at looking: with the chair parked and the key switch off, check the visible rail for anything caught in the teeth, and note where on the rail the noise happens.
Do not try to lubricate, adjust or clean the pinion yourself. If the sound is new, is getting louder, or the chair also judders, book a service.
Grinding that gets worse is how a rack failure begins.
What Light Is Your Companion Stairlifts Stairlift Showing?
Lifts also talk in light. Pick what you can see.
Steady red — on a Companion Stairlifts stairlift
✅ Owner-safe check- Chair parked off its charging strip — the charge indicator has flipped from green to red
- Battery at end of life and no longer accepting a full charge
- A latched fault the controller is holding until service
When a Companion Stairlifts stairlift holds a solid red light, it is telling you a safety circuit is broken or a fault has been stored.
Nine times in ten it is something in plain sight rather than a hidden electrical failure.
Before anything else, park the chair fully on its charging point, swivel the seat back until the lock clicks, and clear anything resting on the footplate or against the armrests.
If the red clears, the lift is safe to use once it responds normally again.
If it does not, stop pressing the call button, leave the power on, and email your service company with the exact indicator state.
Is It Safe to Keep Using It?
Three questions. Ten seconds. Answer honestly.
When to Call an Engineer
The safety chain marks the end of owner checks on a Companion Stairlifts lift. Contact your service provider — or send the form below — if you spot:
- Repeated faulting only minutes after a reset.
- Burning smells, smoke, or visible cable or control damage.
- Water in the pit, machine space or inside the car.
- A car beyond its normal travel or not sitting level at the floor.
- Doors, gates or interlocks operating inconsistently.
Companion Stairlifts servicing
Ask any provider quoting for Companion Stairlifts servicing what is actually included: number of visits, whether the alarm and emergency lowering are tested each time, whether batteries and consumables are covered, and what the response time is when something fails between visits. Two quotes at the same price often describe very different contracts.
Keep every service sheet. A dated history of Companion Stairlifts servicing tells the next engineer which parts have already been changed, supports any warranty claim, and is the first thing a buyer's surveyor asks for when the property changes hands.

Companion Stairlifts maintenance
Day-to-day Companion Stairlifts maintenance is mostly housekeeping, and all of it is safe from outside the equipment: keep charge points and landings clear, keep the stairlift on power rather than isolating it between uses, and keep the door threshold free of grit, rugs and packaging.
Nothing in owner-level Companion Stairlifts maintenance involves removing covers, entering the pit or shaft, or adjusting doors, gates or interlocks. If a check cannot be done from the landing with the equipment behaving normally, it belongs to a qualified engineer.
Frequently Asked Questions
Is my own Companion Stairlifts stairlift covered by this page?
Companion Stairlifts equipment appears in UK buildings across the stairlifts segment. Confirm your exact Companion Stairlifts model from the rating plate before quoting anything to an engineer.
The fault behaviour below is written around what these machines share, not around a single model number.
Where does a Companion Stairlifts stairlift show its fault code?
Companion Stairlifts indications vary by model and control board. No single code list covers the range. Photograph whatever the Companion Stairlifts unit is displaying along with the rating plate, then report both.
Read the sign only — never open a panel or controller to investigate it.
Which Companion Stairlifts problem comes up most often?
The fault this page opens with is "Companion Stairlifts stairlift seat swivel not locked". The Companion Stairlifts chair will not travel. Because the seat isn't sensing as locked in the forward position.
The next most reported Companion Stairlifts symptom is "Companion Stairlifts stairlift battery not charging".
Work through the safe checks listed against each one, note what you observe, and pass that to a competent lift engineer.
All on this page stops at check-and-report: nothing here asks the user or their family to force a door, move a stalled car, remove a panel or enter a pit or shaft.
Is there an official Companion Stairlifts source for fault information?
Ask your maintenance contractor to supply the Companion Stairlifts document that covers your fitting. Makers publish service paperwork to registered trade accounts rather than openly.
Treat this page as orientation and the Companion Stairlifts manual as the authority.
Will a Companion Stairlifts stairlift work in a power cut?
Companion Stairlifts stairlifts of this type run from an onboard battery pack. So the chair normally completes journeys during an outage and simply stops charging until the mains returns.
If your Companion Stairlifts chair will not run on battery at all, that points at the batteries or the charging circuit rather than the outage. The checks on this page separate the two.
