Find out how personal alarms work, the different types available and what to consider before buying one.

Personal alarms allow people to call for assistance if they have an accident or a fall at home. They can help older and less abled people to feel safer at home, and to remain independent for longer. They can also offer peace of mind to family and friends.

Basic personal alarms

Care Needs Care Now Campaign

The care system is failing to provide the support that we and our loved ones need. We're calling for action on care. Help us confront the care crisis by backing our campaign now.

The most basic personal alarms make a loud noise when activated, alerting people nearby that there is a problem. They are very cheap to buy but rely on someone being close by to help.

There are also call buttons that send a signal to a carer’s pager, which can be clipped to their belt or clothing. These have a limited range, so still rely on someone being in the vicinity to help.

At night, the pager sits in a charging unit next to the carer’s bed and if the carer is a heavy sleeper, a vibrating pillow alert can also be attached to some units to help wake the carer.

Alarms that send a signal for assistance

These are devices that are linked via a standalone unit to a 24-hour monitoring service or to a carer, either in your home or elsewhere.

These systems feature a simple push button that is worn around your neck or wrist, or clipped to a belt or clothing. They can also be attached to a mobile phone as an emergency button incorporated into the case.

A number of the systems also have a fall detector incorporated. This means that if you were to fall over, the unit will automatically send an alert to the carer or centre that is responding. Once a call for assistance is sent, the unit also allows you to be found via the GPS system.

If you are caring for someone who has dementia and can lose their direction and fails to return home, you can locate them using the GPS system.

Read about telecare systems to learn about  more sophisticated models that connect to a number of sensors, such as door sensors or a bed /chair sensor, which are especially valuable if you are caring for a relative or friend who has more complex needs, such as dementia. These systems enable you to give assistance if your loved one leaves their home or gets out of their bed in the middle of the night and becomes disoriented.

Choosing and buying a personal alarm

  • Personal alarms are available from a large number of organisations, including local authorities, charities such as Age UK and commercial companies.
  • Think about what type of equipment and level of service you require, as there’s no point paying for more than you need.
  • Take time to compare brands and prices to find the best one to suit your needs.
  • Check the range if you plan to wear it in the garden.
  • Ask how long the batteries will last for; how will you know if they’re running low, and whose responsibility it is to replace them?
  • If you choose a wearable device, is it waterproof? You will probably want to wear it in the bathroom.
  • You might need a key safe (a lockable box outside your home with a spare door key inside) so that authorised people can get into your home if the alarm is sounded. You can buy these separately or from the company providing the personal alarm. We strongly recommend that you buy a police-approved key safe. It may be more expensive, but it's likely to be more reliable.
  • Check that the company you’re buying from is a member of the Telecare Services Association. They offer advice and information as well as a directory of providers.
