When does someone with dementia need a care home?

By CareFinder Team · Published 2026-09-18 · Last reviewed 2026-09-18

Someone with dementia needs a care home when their needs can no longer be met safely where they live, even with extra help. Typical triggers are repeated falls or getting lost, needing help day and night, distress that cannot be eased at home, or a family carer who can no longer cope. No particular stage of dementia sets the date: a needs assessment is the usual first step.

There is no stage of dementia at which a care home becomes compulsory. The time comes when the person's needs can no longer be met safely where they live, even with extra help, or when the person caring for them can no longer carry on. For most families that point arrives gradually, and then is forced by one event: a fall, a night out in the cold, a hospital stay, or a carer's own illness.

This page explains the signs to watch for, who is allowed to make the decision, and the practical steps that come before any move.

Is there a stage of dementia when a care home is needed?

No. Doctors sometimes describe dementia as early, middle and late stage, but these labels do not map neatly onto where someone should live. Some people live at home until the end of their life with a lot of support. Others need a care home while still fairly mobile and talkative, because they live alone and are no longer safe at night.

The Alzheimer's Society says there is no time that is right for everyone, and that a person usually moves because it is no longer possible for them to get the right level of care where they live.

What matters is not the diagnosis but three practical things:

• what the person can and cannot do for themselves now
• what risks they face when nobody is with them
• how much help is realistically available, from family and from paid carers, and for how long

What are the signs that home is no longer working?

No single sign decides it. Look for a pattern that keeps getting worse despite the help already in place.

Safety

• Repeated falls, especially at night or when alone
• Leaving the house and getting lost, or going out at night or in unsuitable clothes
• Leaving the cooker or gas on, letting strangers in, or being taken advantage of
• Missing medicines or taking them twice, even with reminders or a dispenser

Daily care

• Not eating or drinking without someone there to prompt, and losing weight
• Needing help with washing, dressing and the toilet that visiting carers cannot cover
• Incontinence that is becoming hard to manage at home
• Refusing help from family or from paid carers, so care that is arranged does not actually happen

Distress and behaviour

• Fear, agitation or aggression that those at home cannot settle
• Being awake and active most of the night
• No longer recognising their own home and repeatedly asking to go home

The carer

• The main carer's health is failing, or they are exhausted and not sleeping
• The carer is frightened, either for the person or of being hurt
• Care arrangements keep breaking down

The last group matters as much as the first. A care arrangement that depends on one worn-out person is not a safe arrangement. Nobody can be forced to provide care, and saying you cannot go on is not a failure: it is information the council needs to have.

Who decides whether a person with dementia moves into a care home?

This is the part families most often get wrong, in both directions.

If the person can make the decision

If the person has the mental capacity to decide where they live, the decision is theirs. Nobody can decide for them, even if the family thinks the choice is unwise. A diagnosis of dementia does not by itself mean someone lacks capacity.

Under the law in England and Wales, a person has capacity to make a decision if they can understand the information they need, remember it for long enough, weigh up the options, and communicate their choice in any way. Capacity is judged for one decision at the time it needs to be made. It can come and go with dementia, so someone may be able to decide on a good morning and not on a bad evening. A decision that seems strange to you is not proof that capacity has gone.

The person should be given every practical help to decide: simple language, pictures, a visit to see a home, the time of day when they are at their best.

If the person cannot make the decision

If the person lacks capacity for this decision, somebody else makes it, and must act in the person's best interests. That means taking into account what the person wants now, what they said and valued in the past, and the views of the people close to them, rather than what is most convenient for everyone else.

In England and Wales, the Alzheimer's Society explains that an attorney under a health and welfare lasting power of attorney, or a personal welfare deputy, would usually make the decision. If there is nobody with that authority, the decision is normally reached together by family and the professionals involved, such as a social worker. An attorney who only covers property and financial affairs cannot decide where the person lives, but is still involved because they control the money that pays for care.

If family and professionals cannot agree, try to settle it by discussion first. As a last resort, the Court of Protection can decide what is in the person's best interests.

Scotland and Northern Ireland

The principles are similar but the legal documents are different.

• Scotland: decisions about where someone lives fall under a welfare power of attorney, which can only be used once the person has lost the capacity to make those decisions. mygov.scot explains that where no power of attorney exists, someone may have to go to court for a guardianship or intervention order before they can act.
• Northern Ireland: enduring powers of attorney and controllerships cover money and property only, so welfare decisions are usually reached by family and professionals together, in the person's best interests.

Restrictions on leaving the home

Most people with dementia in a care home are not free to walk out alone, and they are supervised for their own safety. In England and Wales, if the person cannot consent to that arrangement, the care home must apply to the local authority for authorisation under the Deprivation of Liberty Safeguards. This is a protection for the resident, with independent assessment, a named representative and a right of challenge. Northern Ireland has a similar system. Expect the home to raise it, and ask if they do not.

What should you do before deciding?

Ask for a needs assessment

The first formal step is an assessment of the person's care needs. It is free, it does not depend on income or savings, and it gives you a professional view of whether the person's needs can still be met at home.

• England: ask the adult social services department of the local council for a needs assessment.
• Wales: ask the local council's social services department, which assesses under the Social Services and Well-being (Wales) Act 2014.
• Scotland: ask the council's social work department, or ask the GP or district nurse to arrange it.
• Northern Ireland: ask the local Health and Social Care Trust for an assessment of need.

If the person already has a care package, ask for a reassessment because their needs have changed. Be there if you can, and describe the worst days, not the best. People with dementia often tell an assessor that they manage perfectly well.

Ask for an assessment of your own needs as a carer

If you provide regular care, you are entitled to your own assessment: a carer's assessment in England, Wales and Northern Ireland, and an adult carer support plan in Scotland. It looks at the effect caring has on your health, work and life, and can lead to breaks from caring and other support. It is also the right place to say plainly what you can and cannot continue to do.

Have the person's health checked

A sudden change in confusion, behaviour or mobility is not always the dementia getting worse. Infections, pain, constipation, dehydration and side effects of medicines can all cause a rapid decline that improves with treatment. Ask the GP to check before you treat a bad fortnight as the new normal.

Try a short stay

Many care homes offer respite stays of a week or two. A short stay gives the carer a rest, shows how the person responds to the home, and makes a later permanent move less of a leap.

Ask about NHS funding if health needs are high

In England, a person whose needs are mainly health needs may qualify for NHS continuing healthcare, which is arranged and paid for by the NHS. Eligibility depends on assessed needs, not on a diagnosis, so dementia alone does not qualify someone. The local integrated care board must assess a person who appears to need it. Wales, Scotland and Northern Ireland have their own arrangements, so ask the social worker or the health board or trust.

What if the decision has to be made in a crisis?

Many moves happen after a hospital admission, when the ward is keen to discharge and the family is told the person cannot go home. It is hard to think clearly in that position.

• Ask what assessments have been done, and ask to be included in discharge planning.
• Ask whether short-term support to recover is possible first. In England, free intermediate care may be offered after a hospital stay for a limited time, usually up to six weeks, before long-term needs are assessed.
• Ask whether a placement can start as temporary, so that a permanent decision is made once the person's condition has settled.
• Do not sign a care home contract or agree to pay fees you do not understand. Ask the hospital social worker who is responsible for funding while assessments are completed.

Is it wrong to feel guilty?

Almost everyone does, particularly if they once promised never to let it happen. That promise was usually made without knowing what the illness would bring.

A move to a care home does not end your role. It changes it, from doing the washing, lifting and night watches to being the person who visits, notices things and speaks up.

If you are struggling with the decision, the Alzheimer's Society support line and the Admiral Nurse helpline run by Dementia UK are both staffed by people who talk families through this every day.

Frequently asked questions

Can someone with dementia be made to go into a care home?

Not if they have the mental capacity to decide where they live: then the choice is theirs, even if others disagree with it. If they lack capacity for that decision, it can be made for them, but only in their best interests and taking their wishes into account. In England and Wales, serious disputes can go to the Court of Protection.

Does power of attorney let me decide on a care home?

Only a welfare power does: a health and welfare lasting power of attorney in England and Wales, or a welfare power of attorney in Scotland. It can only be used for this once the person cannot make the decision themselves, and you must act in their best interests. A financial power alone lets you pay for care, not choose where the person lives.

Does the council have to agree that a care home is needed?

Only if you are asking the council to arrange or help pay for it. Someone paying in full with their own money can move without the council's agreement. An assessment is still worth having, because it records the person's needs and matters if their money later runs down and they need council funding.

Should it be a residential home or a nursing home?

A residential home gives personal care such as help with washing, dressing and medicines. A nursing home gives the same care and also has registered nurses on duty at all times. The needs assessment should say which level the person requires; either kind of home should have staff trained in dementia care.

Key takeaways

• No stage of dementia sets the date. The test is whether the person's needs can still be met safely where they live.
• Look for a worsening pattern: falls, getting lost, not eating, care being refused, distress at night, or a carer at breaking point.
• If the person has capacity to decide, the decision is theirs. If not, it must be made in their best interests, usually by a welfare attorney or by family and professionals together.
• Ask for a needs assessment and a carer's assessment first, and have the GP rule out a treatable cause of any sudden decline.
• Try a respite stay where you can, and avoid making a permanent decision from a hospital bed if a temporary arrangement is possible.
• The rules on assessments, powers of attorney and NHS funding differ between England, Wales, Scotland and Northern Ireland.
