Short-Term and Long-Term Fostering: What Is the Difference?

Start reading about fostering and you will meet the words “short term” and “long term” within about five minutes, usually with nobody stopping to explain them. Most people assume short term means a few nights and long term means forever. Neither is quite right, and the gap puts people off enquiring when it needn’t. Here is what each one actually involves and what the difference feels like across an ordinary week.

Please note: General information about fostering in England, not legal advice about any individual child. Correct at August 2026. Review timescales come from the Care Planning, Placement and Case Review (England) Regulations 2010; the definition of a long-term foster placement from the 2015 amendment regulations. Decisions about a child’s care plan are made by that child’s local authority.

The short answer, before the detail

Short-term fostering gives a child a safe place to live while the adults around them work out what happens next. Long-term fostering is that “next” already decided: a child stays with one family, usually until they are eighteen and often past it. One is a home during the deciding, the other is a home because the deciding is done, and almost every long-term placement in the country began as somebody’s short-term placement somewhere.

• Short term: anything from a single night to roughly two years, while a permanent plan is worked out.
• Long term: a planned, formally agreed arrangement for a child to grow up with one foster family.
• Emergency: the fastest end of short term, sometimes a same-day phone call, to keep a child safe while a better match is found.
• Respite or short break: usually one night to two weeks, often to give a child’s full-time carer some space.

What short-term fostering really involves

Short term is where most foster carers begin, and it covers a wider range than the name suggests. It might be a fortnight while a mother comes out of hospital, or eighteen months while a court works through a case. At Greater London Fostering we describe short-term placements as generally lasting under two years, which surprises people who pictured a weekend. You can see how it sits alongside the other options on our page about the different types of fostering.

The defining feature is not the length. It is that the child’s plan is still open. That means more meetings than a long-term placement, a court timetable you may have to work around, and family time with birth parents that is often more frequent while contact is being assessed. It also means you are asked for a lot of detail: what the child ate, how they slept, what they said in the car. Your recording feeds live decisions.

One thing worth correcting, because it circulates widely and even appears in some training material: looked-after reviews are not simply every three months. The statutory pattern in England is a first review within 20 working days of the child coming into care, a second within three months of that, then at least every six months. Reviews can be brought forward if the child asks for one or the independent reviewing officer wants one.

What long-term fostering really involves

Long-term fostering, sometimes called permanent fostering, has had a legal definition in England since 2015. A placement counts as long term when three things are true: the child’s plan for permanence is foster care, the foster carer has agreed to look after the child until they stop being looked after, and the local authority has confirmed the nature of the arrangement to the carer, the child and the birth parents. That last condition matters more than it sounds. It is the point at which a child is told, in words, that this is their home now.

It is still fostering rather than adoption. Parental responsibility stays where it was, so the local authority keeps a formal say and the child keeps their legal connection to their birth family. That can feel like an odd halfway house until you see the upside: the support package stays in place. The supervising social worker keeps visiting and the fostering allowance carries on, which is why some families who could adopt choose long-term fostering instead.

It also does not stop dead on an eighteenth birthday. Under Staying Put arrangements, set out in section 23CZA of the Children Act 1989, a young person can carry on living with their former foster carers, and the local authority has duties to support that arrangement until they are twenty-one. In practice that often looks like a room kept and somebody to ring when a first tenancy goes wrong.

How a child ends up in one or the other

Nobody makes this decision at your front door. A child comes into care with a care plan, tested and revised at each looked-after review. Where it settles on the child growing up in foster care, the local authority looks for a match and confirms the arrangement formally. If the child in your spare room turns out to need a permanent home, that conversation happens with you rather than around you.

The national picture gives a sense of the timescales. There were 81,770 children looked after in England on 31 March 2025, 67 per cent of them in foster placements, and the average final period in care ran to 893 days. Around one in ten had three or more placements that year, while 69 per cent of under-16s in care at least two and a half years had stayed in the same placement for two years or more. That is the honest version: most children settle, a minority move too often, and good matching is what shifts more into the first group.

The goodbye, and why it should not stop you

This is the question people ask on first phone calls, usually apologetically. Will I get attached, and will it break my heart when they leave? Yes to the first. Sometimes to the second. Carers who were promised it would be fine tend to feel misled the first time a child moves on. The attachment is the work rather than a side effect of it, and a child who leaves you able to trust an adult takes that into the next house.

There are practical ways to make an ending kinder. Keep a memory box through the placement, with photographs and cinema tickets and the odd terrible drawing, so the child leaves with proof the time happened. Tell the new carers what they like for breakfast. And take the ending seriously for yourself: your supervising social worker should be talking it through with you before and after.

What the difference feels like week to week

Short-term placements run hotter in the diary and long-term ones run deeper. Carers who have done both use different muscles.

• Meetings: short term means more of them, sometimes at short notice, sometimes at a contact centre car park you have never driven to before.
• Family time: contact with birth parents is frequently more regular during short-term placements. Our article on what family time actually involves goes into this properly.
• Planning horizon: long-term carers think in school years and holidays booked eleven months out. Short-term carers plan in weeks.
• Your own household: long term asks your family to absorb a permanent new member. Short term asks them to keep opening the door to people who then leave.

Does the pay work differently?

No. At GLF the weekly amount is the same whether a child stays a fortnight or ten years. As at August 2026 our carers receive £479.50 a week for a child under 11 and £507.50 a week for a child aged 11 or over, paid per child and only while a child is placed with you. Where a child has significantly higher or more complex needs, an enhanced weekly amount applies and is agreed placement by placement. It is one fixed weekly fee covering both the cost of caring for a child and your reward element, and we avoid one-off payments for things like birthdays because carers tell us a predictable figure is easier to budget around. There is more on how foster carer pay works.

Which one might suit you?

Our honest position is that you should not settle this before you have spoken to somebody. People who arrive certain they want long term often discover they love the pace of short term, and people who thought they could never bear a goodbye turn out to be very good at them. If your circumstances may change within a couple of years, short term can fit better. If you want to be the person at a child’s graduation, ask about long term. If neither sounds like you, there are other routes in, including parent and child fostering and short break care.

You won’t have to do this alone

Whichever route you take, the support around you is what makes it workable. Every GLF carer has a supervising social worker who visits regularly and knows your household properly, an out-of-hours line a real person answers at two in the morning, and other carers nearby who have been through the same weeks. We are a small agency and intend to stay one. Ofsted inspected us from 21 to 25 July 2025 and rated us Outstanding in all three judgements. There is more detail in our piece on the support foster carers receive.

It is completely normal to have questions at this stage, including the ones that feel too basic to ask out loud. You do not need to have decided anything before you get in touch.

Frequently asked questions

Can a short-term placement become a long-term one?

Yes, and it happens often. If a child’s plan settles on them growing up in foster care and they are already doing well with you, the local authority may confirm the placement as long term rather than move them. It is not automatic, because the arrangement has to be formally matched and confirmed.

Do I have to choose short term or long term when I apply?

No. Your assessment and the fostering panel look at what suits your household, and many carers are approved in a way that allows for both. Plenty of people start with short-term placements and move towards long term later. Approval terms can be varied as things change.

Is long-term fostering the same as adoption?

No. In adoption, parental responsibility transfers permanently to the adopters. In long-term fostering the child remains looked after, the local authority stays involved, and the support and allowances continue. For some children, particularly older ones with strong ties to their birth family, that is the better fit.
