What to Do If the Person You Care For Goes Missing

Someone you care for has not come home.

If someone you care for is missing, look for them around the house, the garden and any outbuildings first. If you do not find them, call 999 immediately1. You do not have to wait 24 hours before reporting someone missing to the police2. If you believe the person is at high risk of harm, call 9993.

The police will want to know who they are, what they were wearing, what medication they take, where they have been found before and what they look like now. Gathering that information before anything happens means you can give it to the police quickly if they go missing4. A Herbert Protocol form does exactly this for someone living with dementia or another condition that puts them at risk of going missing5.

This page sets out what to do in the first minutes, what to tell the police, where to look while you wait, how to prepare a Herbert Protocol form in advance, and what to check when the person comes home. It is written for carers in England, with notes where arrangements differ in Scotland, Wales and Northern Ireland.

Call 999 straight away if they are at risk

The first thing to do is search your own home thoroughly. Look in every room, the garden, sheds, garages and outbuildings, because a person with dementia may be close by but confused about where they are1. If that search comes up empty, ring 999. The police are clear that you should not delay: if you believe the person missing is at high risk of harm, call 9993.

Risk is the test, not the clock. Official guidance names the groups more likely to go missing: children or young people in care, someone with dementia, someone experiencing mental health issues, and members of the Armed Forces4. If the person you care for falls into one of those groups, or needs medication, or cannot communicate easily, treat the situation as urgent from the first minute.

If you cannot use a phone in the usual way, the police offer alternatives. If you are deaf or hard of hearing, use the textphone service 18000, or text 999 if you have pre-registered with the emergencySMS service1.

While you wait, keep your phone with you and stay by it. Have the person's details to hand, and be ready to describe what they were wearing and where they might have gone. If other people are with you, send one of them to check the immediate street and any regular haunts while you make the call.

What to tell the police when you report them missing

When you ring, give the call handler the essentials in this order: who the person is, how old they are, what they look like, what they are wearing, any medical condition and medication, and why you are worried. Then give the places they have been found before or are likely to head for, and your own contact details.

The police advise gathering information about the person now, so you can quickly give it to them if the person goes missing4. A Herbert Protocol form contains a list of information to help the police, including medication required, mobile numbers, places previously located and a recent photograph7. Even without the form, having those four things written down and to hand shortens the call.

What the police will askWhy it matters
A recent photographSo officers and the public know who they are looking for7
Medication requiredA missing person may need medicine while away7
Mobile numbersTo reach the person or people who know them7
Places previously locatedKnown spots to search first7
What they were wearingTo identify them quickly

If you are worried about someone you have not seen for a while and cannot contact, you can also ring your local police force on 101 to raise a welfare concern8. That is for concern rather than an active missing person report, which goes to 999 when the person is at risk.

Where to look first while you wait for help

While the police are on their way, a short, focused search of the places nearest to home is worth doing, but never put yourself in danger. Check the garden, outbuildings, the street, nearby shops and any route the person walks regularly. If you find them in trouble, call 999 and ask for assistance9.

If the person is found unconscious, the NHS advises putting them in the recovery position and telling the ambulance service, checking breathing and pulse, and carrying out CPR if they show no sign of life12.

The Herbert Protocol: a form to fill in before anyone goes missing

The Herbert Protocol is a form that carers, family or friends of a vulnerable person, or the person themselves, can fill in7. It is used in the event of an adult with care and support needs going missing3. Its purpose is simple: the information helps the police and other agencies locate the missing person as quickly as possible and return them to safety13.

The form is designed for people living with dementia or for those supporting someone with a dementia diagnosis who are worried about the possible risk of going missing14. It has been used many times to help police and other agencies quickly and safely locate missing people14. If you know someone with dementia, you can fill one in, and it can help police find them if they go missing15.

You do not need to hand the form to the police in advance. The police only need it at the point the person is reported missing, and the form will be returned once the person is found3. Keep it somewhere you can find it in a hurry, and keep a copy.

For carers of people at risk of going missing because of a mental health condition, a learning disability or dementia, the advice is to collate key information in advance so you can give it to the police immediately if they go missing17. The Herbert Protocol form checklist sets out what to gather, and the guide to what the Herbert Protocol is and how to register explains the scheme in more detail.

Devices and plans that help before anything happens

No device stops someone going missing, but some make finding them quicker. Local authority guidance describes monitored items such as GPS devices that can help a family locate a person who has not returned home or may have got lost18. Telecare can notify someone if you leave your home and would have difficulty finding your way back19. If you live in a rural area, apps such as What3words or Ordnance Survey Locate give emergency crews your exact coordinates20.

A friendly neighbour can also help. Fire safety guidance for people with dementia says that if a person with dementia lives on their own, a neighbour may be prepared to keep an eye out for signs that something is wrong, and you may be able to leave a spare set of keys with them and a phone number where you can be contacted21. The dementia and emergencies guide covers this ground in more depth, and the personal alarms section explains the options for getting help at the press of a button.

When they come home: checks and next steps

When the person is back, tell the police straight away so the search is stood down. Ring 101, the non-emergency number, and say they are safe and home6. If you are at a rest centre or with emergency services, tell the staff there instead, so everyone is accounted for and no unnecessary search is launched6.

Then check the basics. Make sure they are warm enough, ask if they need practical help or are feeling unwell, and keep in touch with them22. If a cold weather alert is in force, check that the person can contact their primary care team if their usual carer is unavailable23. If the person is a smoker and you are an informal carer, reduce any risks you can and notify other agencies such as social services24.

If you are concerned that the person you care for may be experiencing abuse or neglect, report a safeguarding concern to your local authority25. If you are not home when a fire service visit takes place, a postcard is left with the date and time of the call, a reference number and a telephone number you can contact26. Once home after any emergency, contact your insurance company if needed27.

If they go missing from a care home

If the person lives in a care home and goes missing from there, the home should report it to the police. Ring the home first to confirm what has happened and what they have done, then ring 999 yourself if there is any doubt and the person is at high risk of harm3. Give the police the same information you would give from home: description, clothing, medication, places they have been found before and a recent photograph7.

If you are asked to leave a rest centre or emergency accommodation and choose not to stay, tell the emergency services where you have gone and how you can be contacted, by calling 101 or telling rest centre staff, so everyone is accounted for and unnecessary searches are avoided. A carer can do this for you if required28.

Where to get help

The police are your first call in an emergency. For non-emergency concerns, ring 1018. If you have seen the missing person yourself, contact the police on 10129. Ask the officer dealing with your report about support for families, and look up the charity Missing People directly for its current contact details.

For the wider picture of planning ahead as a carer, the carers section covers planning for when you cannot be there, and the carer's emergency plan checklist lists what to write down. The Extra Help section brings together guidance for older, disabled and medically dependent households.

Common questions

Do I have to wait 24 hours before reporting someone missing?

No. Official guidance is clear that you do not have to wait 24 hours to report someone missing to the police. If you have looked around the house, garden and outbuildings and cannot find them, call 999 straight away, particularly if they are at high risk of harm. Waiting gives a missing person more time to travel further and puts them at greater risk.

Will a GPS tracker or location app stop someone going missing?

No device prevents someone leaving, but some help you find them. Local authority guidance describes monitored GPS devices that can help a family locate a person who has not returned home or may have got lost. Telecare can notify someone if you leave your home and would have difficulty finding your way back. In rural areas, apps such as What3words or Ordnance Survey Locate give emergency crews your exact coordinates.

What should I do if the person goes missing from a care home?

The care home should report it to the police. If you are the family carer, ring the home first to confirm what has happened and what they have done, then ring 999 yourself if there is any doubt and the person is at high risk of harm. Give the police the same information you would give from home: description, clothing, medication, places they have been found before and a recent photograph.

Why do people with dementia wander, and what helps?

Official guidance names someone with dementia as one of the groups more at risk of going missing. A Herbert Protocol form, filled in before anything happens, gives police the medication, mobile numbers, places previously located and a recent photograph they need to search quickly. A friendly neighbour with a spare key and your phone number can also keep an eye out if the person lives alone.

What photograph should I keep ready?

Keep a recent, clear photograph that shows the person's face and how they look now, and note what they were wearing when they left. The Herbert Protocol form asks for a recent photograph among its details. Keep a copy on your phone as well as on paper, so you can send or show it the moment you call.

How do I contact the Missing People charity?

The charity Missing People supports families of missing people, but this page cannot give its phone number or opening hours because they are not confirmed here. Ask the police officer dealing with your report to put you in touch with the charity, or look up Missing People directly. The police remain your first call in an emergency.

How do I tell the police the person has been found?

Ring 101, the non-emergency number, and tell them the person is safe and back home, so the search is stood down. If you are at a rest centre or with emergency services, tell the staff there instead. The same principle applies whenever you leave a place where people are accounting for you: say where you have gone and how you can be contacted.
