What Is Fall Detection?
Fall detection is a technology built into personal alarm devices that can automatically detect when the wearer has fallen. When a fall is detected, the device triggers an alert without the wearer needing to press a button. This is critically important because many falls result in the person being unable to reach or activate a manual alarm, whether due to injury, confusion, or loss of consciousness.
Falls are the most common cause of injury-related death in people over 75 in the UK. Around one in three people aged 65 and over will fall at least once a year. Fast response after a fall dramatically improves outcomes, which is why automatic fall detection can be life-saving.
How Does Fall Detection Work?
Fall detection devices use a combination of sensors to identify when a fall has occurred:
- Accelerometers measure sudden changes in speed and direction, detecting the rapid downward movement of a fall
- Gyroscopes measure changes in orientation, detecting when the wearer has gone from upright to horizontal
- Barometric pressure sensors (on some devices) detect changes in altitude, which helps distinguish a genuine fall from sitting down quickly
The device’s software combines data from these sensors to determine whether the movement pattern matches a fall. If it does, the alarm is triggered automatically after a short delay (usually 30 seconds), giving the wearer time to cancel a false alarm if they are fine.
Types of Fall Detection Devices
Fall Detection Pendants
These look and work like a standard personal alarm pendant but include fall detection sensors. They connect to a base unit at home and are monitored by a 24/7 call centre. This is the most common type for home use.
Fall Detection Watches
Smartwatch-style devices with built-in fall detection and GPS. These work both at home and outdoors. This makes them more versatile than pendant-based systems. Many also include heart rate monitoring and step counting.
Fall Detection Wristbands
Simpler than smartwatches, these are lightweight wristbands focused purely on fall detection and alerting. They suit people who find smartwatches too complex or bulky.
Smartphone Fall Detection
Some smartphones (including recent iPhones and Samsung Galaxy models) have built-in fall detection that can automatically call emergency services. However, this only works if the person has their phone with them and charged, which is not always reliable for elderly users.
How Accurate Is Fall Detection?
No fall detection system is 100% accurate. There are two types of error to be aware of:
- Missed falls (false negatives) – the device fails to detect a genuine fall. Slow, controlled falls (like sliding off a chair) are harder to detect than sudden, hard falls
- False alarms (false positives) – the device triggers when no fall has occurred. Vigorous movements like clapping, banging a table, or dropping the device can sometimes trigger false alerts
Modern devices are significantly more accurate than early models, but you should not rely on fall detection as your only safety measure. It works best as an additional layer of protection alongside a manual alarm button.
Costs
- Home pendant with fall detection (monitored): ยฃ20 to ยฃ30 per month
- GPS watch with fall detection (monitored): ยฃ25 to ยฃ40 per month
- Council telecare with fall detection: often available for ยฃ5 to ยฃ10 per week
- One-off purchase devices (unmonitored): ยฃ80 to ยฃ250
Fall detection is usually offered as an optional add-on to a standard personal alarm package, adding ยฃ2 to ยฃ5 per month to the base monitoring cost.
Who Should Consider Fall Detection?
Fall detection is particularly recommended for people who:
- Live alone and are at risk of falls
- Have a history of falls or near-falls
- Have conditions that increase fall risk, such as Parkinson’s, epilepsy, low blood pressure, or balance disorders
- May not be able to press an alarm button after a fall due to injury, confusion, or loss of consciousness
- Have dementia or cognitive impairment that might prevent them from using a manual alarm
Tips for Getting the Most from Fall Detection
- Wear the device at all times, including in the shower and at night, as these are high-risk times for falls
- Choose a waterproof device so it can be worn in the bathroom
- Keep it charged and establish a regular charging routine
- Test it regularly by pressing the manual button to confirm it connects to the monitoring centre
- Understand that it is not perfect and continue to take other fall prevention measures such as removing trip hazards and using grab rails

Before you buy: the January 2027 phone switchover
The UK is retiring its analogue telephone network, and the deadline for the move to digital lines is January 2027. Older personal alarms that dial out over an analogue landline can stop working once a line is switched. In August 2025 Which? reported that three of the seven major alarm providers it examined were still selling analogue alarms, and called on Trading Standards and the Office for Product Safety and Standards to take them off sale.
The practical rule if you are buying now: choose a device that connects over the mobile network using its own SIM, or a digital alarm the provider will confirm in writing works on a digital line. If you already have an alarm, ring the provider and ask whether the unit is digital ready. An alarm that works today is not automatically an alarm that works after your line is switched.
The standard covering social alarm equipment is BS EN 50134. Monitored providers can also hold accreditation under the TSA Quality Standards Framework, which is a reasonable filter when comparing companies.
Fall detection devices you can buy on Amazon today
Two very different products get sold under the same words. A monitored alarm sends the alert to a 24 hour response centre where a person talks to the wearer, calls a keyholder and arranges an ambulance if one is needed. That carries a monthly fee. A self monitored device, which is almost everything sold on Amazon, rings or texts the family numbers you programme into it yourself. There is no monthly fee, and nobody is on the other end unless a relative answers.
Neither is better in the abstract. If the person lives alone with no family within half an hour, a monitored service earns its fee. If there is a son or daughter nearby who will always pick up, a one off purchase makes sense. What matters is knowing which one you are buying, because the listings blur the two.
Check three things on any device here: whether it needs a SIM card and a data plan, whether a detected fall actually dials out or only sounds an alarm in the room, and how long the battery lasts between charges. Accelerometer based detection also false alarms on sudden sitting and can miss a slow slide to the floor, so treat automatic detection as a backstop to a button press rather than a replacement for one.
We have not tested these devices. The table below shows what is currently listed on Amazon UK with live prices, and the notes under each one set out what the listing claims and what you should confirm before you buy.

Best for no monthly fee: one time cost medical alert watch
Sold explicitly on the no contract, no monthly fee proposition, with fall detection built in. If your objection to a monitored alarm is the ongoing cost rather than the service, this is the shape of product you are looking for. It is the most expensive item in the table, so the sum only works out if the person keeps it for several years.
The catch: no monthly fee also means no response centre. The alert goes to the numbers you programme, so somebody has to be reachable. Confirm on the listing whether a SIM is included and whether calls are chargeable. Around £150.

Best two way voice: SOS alarm marketed for dementia
Two way voice matters more than any other feature for someone with memory problems, because it lets a relative talk to them through the device rather than guessing what has happened from a silent alert. This one is sold with an SOS button, fall detection and two way calling together.
The catch: a device someone can talk through is also a device someone can be confused by. If the wearer will not recognise a voice coming from their wrist, that feature is not worth paying for. Around £130.

Best mid price watch with tracking: Weyot fall detection watch
Sits between the budget watches and the alarm branded devices, and combines fall detection with location tracking, which is the pairing most families actually want if the person still goes out alone.
The catch: location tracking on a watch is only as good as the network where the person walks, and it raises a consent question if they have not agreed to being tracked. Around £70.

Best budget option: entry level senior watch with SOS
The cheapest realistic way to put fall detection and an SOS button on someoneโs wrist. Worth considering as a first step for a person who has not fallen yet but is starting to feel unsteady, where spending a hundred and fifty pounds is hard to justify.
The catch: at this price the detection is basic and the build is unbranded, so expect more false alerts and a shorter life. Around £50.

Best if tracking matters as much as alerting: GPS personal SOS alarm
An alarm sold around its location features rather than its watch styling, which suits someone who will not wear a smartwatch but will carry or wear a dedicated alarm unit.
The catch: check the form factor on the listing before ordering, because pendant, clip and wristband versions of this type of product look similar in photographs and suit very different people. Around £135.

Frequently asked questions
Do I have to pay a monthly fee for fall detection?
No. Monitored alarms charge a monthly fee because a staffed response centre answers the alert. Self monitored devices, which is most of what Amazon sells, are a one off purchase and call the family numbers you programme in. Some still need a SIM card with credit or a small data plan, so check that before you assume there are no running costs.
Will my personal alarm still work after the 2027 phone switchover?
Only if it is digital ready or connects over the mobile network. The analogue telephone network is being retired with a deadline of January 2027, and alarms that dial out over an analogue landline can stop working when a line is switched. Ring your provider and ask them to confirm in writing that your specific unit works on a digital line.
How accurate is automatic fall detection?
Good enough to be worth having, not good enough to rely on alone. Detection works by sensing a sharp change in speed and orientation, so it picks up a hard fall well, false alarms on sudden sitting or dropping into a chair, and can miss a slow slide down a wall to the floor. Treat it as a backstop to a button press.
Can a smartwatch do fall detection instead?
Yes, several mainstream smartwatches include fall detection and emergency calling. The trade off is charging and comfort: a smartwatch usually needs charging every day or two and has to be worn to work, which is exactly the point where older users stop wearing it. A device with a week of battery is often the more practical choice.
Does the NHS recommend fall detection devices?
Not specifically. The NICE falls guideline published in 2025 recommends a home hazard assessment using a validated tool, and strength and balance training, for people at risk of falling. It does not make a recommendation on fall detection wearables. A device helps you get help faster after a fall, it does not reduce the chance of falling, so it should sit alongside the measures NICE does recommend rather than instead of them.
Is fall detection worth it if someone is not living alone?
Sometimes. The risk it addresses is a long lie on the floor with nobody knowing, and that can happen in a shared house if the other person is out, asleep upstairs or unable to lift them. If the household is out for hours at a time, it is worth it. If someone is always in earshot, spend the money on grab rails and lighting instead.
