How they work
A pendant or wristband connects to a base unit in the home. Pressing the button opens a line to a monitoring centre, which speaks to the person and calls a nominated contact or the emergency services.
Some add automatic fall detection, though these produce both false alarms and missed falls, so treat detection as a bonus rather than the reason to buy.
What they cost
Typically a modest monthly fee, sometimes with a setup charge. Many councils offer a scheme, and some charities subsidise them, so check locally before signing a private contract.
Ask about the contract length and the cancellation terms, which are where the unpleasant surprises usually live.
Where they fall down
- They only work if worn. Many end up on a bedside table.
- They only work if pressed, which is exactly what an unconscious or badly shaken person cannot do.
- Most work only within range of the base unit, not in the garden or the shops.
- They do nothing at all about the slow problems: skipped meals, dehydration, isolation.
How to choose, and what to pair it with
Pick monitored over family-call-only if nobody local can respond. Check it is digital-ready for the phone switchover, and confirm the response process in writing.
Then pair it with something preventative. An alarm covers the worst day; scheduled reminders cover the other three hundred and sixty-four.
