Fall-detection watches and wearable alarms

Last checked November 2026. Offers and rules change: confirm with the provider before you rely on them.

A fall-detection watch or wearable alarm senses a hard fall and calls for help automatically, even if you cannot press a button. The key choice is who it calls: a 24-hour monitoring centre, or your own family. No device catches every fall, so treat it as a safety net rather than a guarantee.

Who a wearable alarm suits

These devices suit people who live alone or spend long periods alone, anyone who has fallen before or feels unsteady, and active people who walk, garden or travel on their own and want cover outside the house. If you only need cover indoors, a traditional pendant linked to a base unit may be simpler and cheaper; see our guide to personal alarms.

If you have had a fall, or are worried about falling, tell your GP. Falls often have treatable causes, and our guide to preventing falls at home covers practical steps.

The main types

Monitored pendant or wristband with fall sensor (home-based). Works with a base unit in your home. A fall or button press connects you to a monitoring centre, whose staff speak to you through the base unit and call family or an ambulance. Range covers the house and usually the garden.
Monitored mobile (GPS) alarm. A pendant or watch with its own mobile connection and location finder, so it works anywhere with mobile signal. You speak to the monitoring centre through the device itself.
Family-monitored alarm watch. Similar hardware, but an alert rings and texts your chosen contacts rather than a call centre. Cheaper, but only as reliable as your contacts' availability.
Mainstream smartwatch with fall detection. Some smartwatches from the big phone makers detect a hard fall, ask if you are all right and, if you do not respond, call the emergency services and message your emergency contacts. They also tell the time, count steps and more, but need charging every day or two.

What to look for

Who answers. A monitoring centre staffed all day and night, or family? Be realistic about whether relatives can always pick up.
Where it works. Home only, or anywhere? Mobile devices should use a SIM that connects to more than one network for better coverage.
4G. Ofcom has warned that some care alarms rely on the 2G mobile network, which UK operators plan to switch off over the coming years. Choose a 4G device and ask the supplier to confirm it.
Battery life and charging. From a day (smartwatches) to several weeks or more (simple pendants). A device that is on the charger is not on your wrist. Look for an easy drop-in charger and a low-battery alert sent to family.
Waterproofing. Many falls happen in the bathroom. It must be safe to wear in the shower.
Comfort. You will only be protected if you wear it, so choose wrist or neck according to what you will actually keep on, including at night.
A manual help button that is easy to find and press.
Two-way speech through the device.
Contract terms. Minimum term, cancellation, and what happens to the equipment afterwards.
Standards. Ask whether the monitoring service is certified by the TEC Services Association (TSA), the UK industry body for technology-enabled care.

Watch out: Fall sensors detect a sudden drop followed by stillness. They can miss slow falls, slides from a chair or a gentle collapse, and they sometimes raise false alarms when you sit down heavily. Always press the button yourself if you can, and never assume the device will have noticed.

Rough price guide

As a rough guide at the time of writing (November 2026):

Type	Typical cost
Council or housing association alarm service	Often a modest weekly charge; some are free or subsidised if you qualify
Private monitored home alarm with fall sensor	Around £15 to £30 a month, sometimes plus a set-up fee
Private monitored mobile (GPS) alarm	Around £20 to £35 a month, sometimes plus the device
Family-monitored alarm watch	Around £50 to £150 for the device, plus a SIM plan
Mainstream smartwatch with fall detection	Around £200 to £450, plus a mobile plan if it is to work without your phone

Start by asking your council's adult social care department what its telecare or community alarm service offers; it is often the best value, and an assessment is free. If you have a long-term illness or disability, alarm equipment and monitoring may qualify for VAT relief: see our VAT relief guide and ask the supplier. Attendance Allowance, if you receive it, can be put towards the cost.

Setup tips a family member can help with

Give the provider accurate details: address, health conditions, medication, and who holds keys.
Fit a key safe so responders can get in without breaking the door.
Add at least two emergency contacts who live nearby and usually answer.
On a smartwatch, check that fall detection is switched on. It is not always on by default, so look in the watch's safety settings.
Do a test call together so the wearer knows what happens and is not alarmed by the voice.
Agree a routine for charging, such as during breakfast, never overnight.
Press the test button monthly, as the provider advises.

Mistakes to avoid

Leaving it on the bedside table. Night-time trips to the bathroom are when it is needed most.
Choosing a stylish smartwatch for someone who will not charge it.
Relying on family alone when they work, travel or silence their phones at night.
Signing a long contract on the doorstep or over the phone under pressure. Compare providers, and see doorstep selling rights.
Forgetting the landline change. Older home alarm units that plug into the telephone socket may be affected by the landline digital switchover. Tell both your alarm provider and your phone provider.

Common questions

Can I get a fall-detection alarm free?

Sometimes. Councils may provide telecare free or at reduced cost after a care needs assessment, depending on your circumstances and where you live. Rules differ between England, Scotland, Wales and Northern Ireland.

Does the watch need a mobile phone?

Dedicated alarm watches have their own connection. Mainstream smartwatches either rely on your phone being nearby or need their own mobile plan.

What happens if I set it off by accident?

Nothing bad. Tell the operator, or cancel the alert on the watch. Providers expect false alarms and would rather have them.

Will the ambulance come faster?

The alarm gets the call made quickly and passes on your details and location. Response times are the same as for any 999 call.
