Choosing a personal alarm for an older parent

The first question is not which alarm to buy. It is who answers when the button is pressed at three in the morning, and who can then get through the front door. Settle that, and the choice between a pendant, a mobile alarm and a watch becomes much simpler.

Part of our guide to elderly care.

Who answers the call

Start with who answers when the button is pressed

A personal alarm is a button your parent wears that opens a call for help. The button is the same on every kind. What differs is who is on the other end of the call, and whether that person can get to your parent.

Who answers when the button is pressed, and who comes to the door

A family-call alarm

Sometimes sold as unmonitored

Who picks up
The phones on a list you set up, rung one after another until somebody answers.
Who comes to the door
Whoever answered, or whoever they can send. If nobody can get there, they ring 999.
What you pay for
The device, and on some models a mobile SIM. There is no monitoring charge because nobody is employed to answer.
It suits
A parent with two or three people living close by who will answer at any hour and hold a key.
Watch for
A list that comes down to one person who works, sleeps, drives or goes on holiday. Every missed call adds to the time on the floor.

A monitored alarm

Bought from a company

Who picks up
Staff at a monitoring centre that answers day and night, with the details you gave them about your parent in front of them.
Who comes to the door
The centre rings the family or the named neighbours, or calls an ambulance. Some companies run their own response visits as an extra.
What you pay for
The equipment, bought or rented, and a monitoring charge every month or year, sometimes with a connection fee.
It suits
A parent whose family live some distance away, or where the list of people who could answer is short.
Watch for
Minimum terms, call-out charges for response visits, and what happens to the contract during a hospital stay.

The council's alarm service

Often called a lifeline or telecare

Who picks up
A monitoring centre the council runs or pays for, answering day and night in the same way as a private one.
Who comes to the door
Named contacts, an ambulance, or in some areas a local response team the scheme employs. Ask which applies in your parent's postcode.
What you pay for
In England, aids, and minor adaptations of £1,000 or less, that the council provides after an assessment must be free. Monitoring is a service, and councils can charge for it.
It suits
Any family as a first call, because the assessment is free and looks at falls and the house as well as the alarm.
Watch for
Waiting times for an assessment, and a charge set after a financial assessment rather than a fixed price.

Each route can use a pendant on a base unit, a wrist button, a mobile alarm with GPS or, for some family-call set-ups, a watch. The device is a separate choice from who answers it, and it comes second.

The NHS describes the same choices in its guide to personal alarms, monitoring systems and key safes: basic alarms that make a loud noise, alarms that send an alert to a family member's phone, and monitored alarms that alert a 24-hour monitoring service. A loud alarm only helps if somebody lives close enough to hear it, so for a parent living alone the choice is between the second and the third.

When a family-call alarm worksSection titled When%20a%20family-call%20alarm%20works

A family-call alarm, sometimes sold as an unmonitored alarm or an alarm that contacts family, rings a list of numbers in turn until somebody picks up, and then opens a speaker call so you can talk to your parent. It costs less to run because nobody is paid to wait for the call, and it works when the people on the list live close by, will answer at night and can get in.

If the list comes down to one daughter who works shifts or lives 40 miles away, every unanswered call adds minutes to the time your parent spends on the floor. Ask how many numbers the device holds and what it does when none of them answer: some ring the list again, and some can call 999.

When a monitored alarm is the safer choiceSection titled When%20a%20monitored%20alarm%20is%20the%20safer%20choice

A monitored alarm rings a centre that is staffed day and night. The person who answers has the details you gave when you signed up: your parent's name, their conditions, who to ring and whether there is a key safe. They can talk to your parent through the base unit, ring the family, and call an ambulance if it is needed. That is the better fit where family live some distance away or the list of people who could answer is short.

The council route, usually called a lifeline, community alarm or telecare, is a monitored service too, run by the council or a provider it pays. In some areas the scheme employs a response team who can come out to help somebody up from the floor; in others the centre rings the named contacts. Ask which applies in your parent's postcode.

This page is about making the choice. For what each device does and does not do, pendant alarms and sensors has the detail, and technology that helps an older person live alone covers sensors, reminders and cameras. Both sit within the elderly care guides.

Pendant, mobile or watch

A pendant at home, a mobile alarm for going out, or a watch

Once you know who should answer, the device follows from where your parent spends their day and what they will wear without complaint.

Pendant or wrist button with a base unit

Where it works
In the house and, depending on range, the garden, within range of the base unit in the hall or living room.
Charging
The button runs on a long-life battery. The base unit is plugged into the mains.
What to check
The range in metres, whether the button is waterproof for the bath and shower, and battery back-up in the base unit.

Mobile alarm with GPS

Where it works
Anywhere with a mobile signal, so on the way to the shops and in the park as well as at home.
Charging
Has to be charged regularly, and a flat battery means no alarm.
What to check
Which mobile network it uses and how good that signal is at your parent's house, and who sees the location.

Alarm watch or smartwatch

Where it works
Anywhere it has a signal or is within range of a paired phone, depending on the model.
Charging
Usually charged daily, which means it comes off every day.
What to check
What the SOS button and fall detection call: family, a monitoring centre or 999. This varies a great deal between devices.

Ask a supplier to tell you in writing who each device calls, and to show you how it is set up. Words such as monitored and fall detection are used loosely in adverts.

The best device is the one your parent keeps on. A pendant taken off at bedtime misses the hours when people get up to the toilet in the dark, while a waterproof wrist button can stay on in the shower and in bed. If your parent already wears a watch and is used to charging a phone, a watch may be accepted where a pendant would sit in a drawer. If charging is likely to be forgotten, a home pendant with a long-life battery is the safer choice.

Fall detection, and what it cannot promiseSection titled Fall%20detection%2C%20and%20what%20it%20cannot%20promise

Some alarms offer automatic fall detection, which raises a call without anybody pressing the button. It looks for a sudden drop, an impact and then stillness. That is worth having for somebody who might faint or be too shaken to press anything, but no detector catches every fall. When researchers tested 13 published fall detection methods against 29 falls recorded in real life rather than acted out, they caught on average 57% of the falls and the best caught under 83%. Over a day of recording, the same methods raised between 3 and 85 false alarms depending on which was used (Bagalà and colleagues, PLOS ONE, 2012). It tested methods rather than products on sale today. Ask any supplier what happens after a false alarm and how often your parent can expect one, and treat fall detection as a second chance behind the button rather than a replacement for pressing it.

GPS, and asking your parent firstSection titled GPS%2C%20and%20asking%20your%20parent%20first

A mobile alarm with GPS shows where the person is when they press it, and some let family check the location at any time. That helps somebody who still walks to the shops alone. For a parent with dementia it raises the question of consent. Under the Mental Capacity Act your parent is assumed to be able to make this decision unless it has been shown otherwise, and they should be part of it. The Alzheimer's Society's advice on using technology covers how to have that conversation, and if leaving the house is the worry, read wandering and leaving the house as well.

The council and the cost

Free alarms, council schemes and what you may have to pay

A search for free personal alarms leads back to the council. Some parts of what a council offers are free by law and some are not, and it helps to know which before you ring.

  1. 1

    Ask the council for a care needs assessment

    Free to ask
    Ring adult social care where your parent lives and say you are worried about falls and would like an alarm considered. The gov.uk page on applying for a needs assessment finds the right council from a postcode. The assessment looks at the whole picture, including the house and the help your parent already has.
  2. 2

    Find out which part is equipment and which is the service

    The question that decides the cost
    In England a council must not charge for aids, or for minor adaptations costing £1,000 or less, that it provides after an assessment. Monitoring is a service, and councils can charge for it after a financial assessment. Some charge for their alarm service and some do not, so ask.
  3. 3

    Check the VAT position if you buy privately

    0% for a long-term condition
    An alarm designed for a disabled person, supplied to them for their own use, is zero rated, and so is the monitoring centre's service. The test is a long-term condition with a substantial effect on everyday activities. Being over 60 on its own does not count, and the 5% rate for older people covers some mobility aids but not alarms.
  4. 4

    Look at Attendance Allowance

    £76.70 or £114.60 a week
    If your parent is over State Pension age and needs help with personal care or supervision, Attendance Allowance is not means-tested and can be spent on whatever helps, including an alarm bought privately.

You can find the right council on gov.uk through apply for a needs assessment by social services. The rule on what must be free is in regulation 3 of the Care and Support (Charging and Assessment of Resources) Regulations 2014, and it is worth having to hand if you are told everything carries a charge. What equipment an older person can get free covers the rest of what the council and the NHS lend or fit, and how council funding works explains what happens after the assessment.

The VAT relief is set out in section 7 of HMRC's notice on reliefs from VAT for disabled and older people. The supplier should give you a short declaration to sign confirming your parent is eligible, kept separate from the order form; HMRC publishes a template for that declaration. A price quoted with VAT added is worth querying if your parent has a long-term condition such as diabetes. The Attendance Allowance figures are the 2026/27 weekly rates, and claiming Attendance Allowance goes through the form.

Before you sign

Contracts, cancelling and the questions to ask a supplier

The cost that catches people out with an alarm is paying for months after it has stopped being used. These questions find out how a contract works before you sign it.

The price

What to ask
Every charge in writing: the device, connection or installation, the monthly or yearly monitoring, and any charge for response visits.
Why it matters
A low monthly figure can sit beside a large connection fee or a charge each time somebody is sent out.

The term

What to ask
Is there a minimum term, how much notice ends it, and is the equipment bought or rented?
Why it matters
Buying the device outright with a rolling monthly plan, or a family-call alarm with no monitoring, is how you avoid a long contract.

A hospital stay

What to ask
Can the service be paused during a hospital stay, and what happens if your parent moves into a care home?
Why it matters
This is when families find they are still paying for an alarm nobody is wearing.

The sales visit

What to ask
Is a discount only on offer if you sign today?
Why it matters
A same-day-only price is a reason to walk away. A fair price will still be there next week.

The certification

What to ask
Is the monitoring service certified under the Quality Standards Framework?
Why it matters
It is the audited standard for alarm and telecare services, and the register of certified organisations is public.

The phone line

What to ask
Does this unit work on a digital line, how many hours does its battery last in a power cut, and who pays if it has to be replaced?
Why it matters
Older base units that plug into the phone socket are the ones the switch to digital lines affects.

The warranty

What to ask
What happens if the button or base unit fails, and how quickly is it replaced?
Why it matters
An alarm that is away for repair for a week leaves a week without cover.

These are questions to ask, not a judgement on any company. We do not name or rate alarm providers.

Your right to cancel within 14 daysSection titled Your%20right%20to%20cancel%20within%2014%20days

If the alarm is bought over the phone, online or from a salesperson in your parent's home, the Consumer Contracts Regulations give a right to cancel without giving a reason. For the equipment, the 14 days run from the day it arrives. For a service such as monitoring, they run from the day the contract is made. That is set out in regulation 30 of the Consumer Contracts Regulations 2013. If a salesperson visits, be there if you can and ask for the terms in writing.

Where independent views come fromSection titled Where%20independent%20views%20come%20from

We do not rate alarms or the companies that sell them. Which? publishes buying advice and its own testing for personal alarms. TEC Quality runs the certification scheme for the Quality Standards Framework and keeps the public register of certified providers, so you can check a name before you sign. Age UK's guide to telecare covers what to compare when you shop around.

While you are arranging the alarm, sort out how somebody gets in. However quickly a call is answered, somebody still has to get through the door. Key safes for carers and family covers which kind to fit and who should have the code.

The phone line change

Check any alarm against the January 2027 phone line change

Landlines across the UK are moving from the old analogue network to digital lines that run over broadband. Government guidance expects most customers to have moved by the end of January 2027.

Ask the alarm provider about the unit

Ask whether this base unit works on a digital line, and if not, what replaces it and who pays. Newer alarms are built for digital lines or use a mobile SIM.

Have the model number ready

Tell the phone company there is an alarm

Providers have committed not to move a telecare user to a digital line without a working alarm in place, and they can only do that for households they know about.

Even if nothing has changed yet

Ask about power cuts

A digital phone line does not work in a power cut without a battery. Ofcom guidance, set out on gov.uk, says providers should have at least one way to reach the emergency services for at least an hour, offered free to people at risk because they depend on their landline.

A digital line needs power

Consider a mobile alarm

An alarm with its own SIM does not depend on the landline at all, though it does depend on a mobile signal at the house. Ask the supplier to check coverage at the address.

If the line is a worry

The risk is an older unit, still plugged into the phone socket, on a line that is upgraded without anybody connecting the two. The government's guidance on the transition from analogue to digital landlines sets out the commitments made to telecare users, including the power cut rule, and the connectivity timeline has the dates. The Telecare National Action Plan explains what councils and providers have agreed to do.

Alongside a carer

An alarm calls for help after a fall, and a carer helps prevent one

An alarm is for the moment something has already gone wrong. A visit is for the days in between, when somebody notices the things that come before a fall.

A morning visit

The first hour of the day is when people are stiff, dizzy from new tablets or rushing to the toilet. A carer there for it costs £18 to £25 an hour on PrimeCarers with our fee included, against £28 to £35 through an agency.

Getting up, washed and dressed

Company and checking in

A companion who calls in for a walk, the shopping or a cup of tea sees whether your parent is eating, drinking and wearing the alarm. Companionship visits are £15 to £20 an hour on PrimeCarers with our fee included.

A few hours a week

Someone there at night

If the alarm keeps going off at night, or the falls happen on the way to the toilet, a night carer may be the better answer. On PrimeCarers a sleeping night costs £130 to £145 and a waking night £165.

When nights are the worry

The alarm stays

A carer and an alarm do different jobs. The carer can make sure the pendant is on and charged, and the alarm covers the hours between visits.

For the hours nobody is there

For a parent who lives alone, the family may be both the people on the alarm list and the people doing the checking in. If that has become too much, you can search for carers near you and compare their rates. A morning visit every day is seven hours a week, £126 to £175 at the rates carers charge here. Care for someone who lives alone shows how families put a week together, companionship care covers visits for company and checking in, and falls and toilet trips at night covers night care.

PrimeCarers is an introductory service, not an agency. Carers are self-employed and set their own rates. Before a carer appears in a search we check their identity and right to work, confirm an enhanced DBS check (or PVG in Scotland, Access NI in Northern Ireland) issued within the last 2 years, and interview them online. We do not check qualifications, training or references, so the references and reviews on a profile are for you to follow up with the carer. Separately from those checks, visits booked through PrimeCarers are insured, within the terms of the policy.

Questions

Questions families ask about personal alarms

Ask the council. In England, after a care needs assessment, a council must not charge for aids, or for minor adaptations costing £1,000 or less, that it provides, but it can charge for the monitoring service after a financial assessment. Some councils charge for their alarm service and some do not. If your parent is disabled or has a long-term illness, an alarm designed for them and bought privately can be free of VAT, and Attendance Allowance can help with the running cost.

Yes. A family-call alarm, sometimes sold as unmonitored, rings a list of phone numbers in turn until somebody answers. It works when two or three people nearby will answer at any hour and can get into the house. If the list comes down to one person, or the family live a long way off, a monitored alarm is the safer choice.

Usually, yes. A family-call alarm bought outright has no monitoring charge, and some monitored services run month to month. Ask for the minimum term and the notice period in writing before you sign. If you buy by phone, online or from a salesperson at home, you have 14 days to cancel.

The best one is the one your parent will wear, answered by somebody who can reach them. For a parent living alone without family close by, that means a monitored alarm, through the council or a company, with a waterproof wrist button or pendant and a key safe by the door. We do not rate brands. Which? publishes independent buying advice.

It can be, for a parent who already wears a watch and will charge it. Fall detection is a useful second chance, but no detector catches every fall, and it raises false alarms. Before you buy, find out who the watch calls when it detects a fall: family, a monitoring centre or 999. This varies between devices.

It depends on the unit. Ring the alarm provider with the model number and ask whether it works on a digital line. Then tell the phone company there is an alarm at the address, because they have committed not to move a telecare user without a working alarm in place. Ask about battery back-up for power cuts at the same time.
