Fostering a Teenager: What It’s Really Like

Most people who ring us picture a small child. A five-year-old holding a cereal bowl, maybe a baby. Hardly anyone rings up and asks to foster a fifteen-year-old. So this is about what fostering a teenager actually asks of you, and why some people turn out far better at it than they expected.

Please note: This is general information about fostering in England, not personal advice. The national figures and leaving care entitlements below are correct at August 2026, from the Department for Education’s children looked after statistics (published 26 November 2025), Ofsted’s Fostering in England data and government guidance on leaving care. Entitlements for any individual young person are decided by their local authority.

Teenagers are a much bigger part of the picture than people expect

There were 81,770 children in the care of local authorities in England on 31 March 2025, and more than a quarter were sixteen or older. That share has climbed for years while the number of foster carers has quietly fallen. More households left fostering last year than joined it, and that arithmetic is why older children so often end up placed a long way from home.

• 81,770 children looked after in England at 31 March 2025, with 67% in foster placements
• 27% were aged 16 or over (22% excluding unaccompanied asylum-seeking children), and that number has risen by 17% in five years
• 42,190 fostering households at 31 March 2025, down 1% on the year: 4,690 deregistered while 4,430 joined
• The Fostering Network estimates England needs around 5,000 more fostering families
• In February 2026 the Department for Education committed to 10,000 more foster places by 2029, noting children now enter care at an older age than they used to

None of that is a reason to foster a teenager out of duty. It is context for why the conversation gets noticeably more animated when you ring an agency and say you are open to older children.

The fear is usually about being rejected

When people say they could not foster a teenager, they rarely mean they are frightened of slammed doors. What they usually mean, once you get past the first answer, is that they are frightened of putting a lot of love into someone who does not want it. Worth naming, because something like it does happen. A sixteen-year-old who has already moved four times will not arrive at your door and hug you. They may be polite and completely closed for weeks.

Here is the part nobody tells you: that is not failure. It is a sensible response to their own history, and it is where your job actually starts. Trust in an older young person tends to arrive sideways, months in, at half past eleven at night when they suddenly want to talk about something that happened in Year 8. Understanding how trauma and attachment shape the way a young person behaves makes those weeks much easier to sit with. You are not being tested for patience. You are being checked, over and over, for whether you are still there.

Your role shifts from doing things for them to standing behind them

With a younger child you are largely a caretaker. With a teenager you become closer to a supporter, the harder role, because it means watching someone make choices you would not make. Many young people who come into care as teenagers have already carried adult-sized responsibilities, sometimes looking after a parent or younger siblings. Being allowed to be a child again can feel insulting. A fifteen-year-old bristling at a bedtime is often not defiance but someone who has been in charge of themselves for years.

The work breaks down into three kinds of safety. Physical: food they like in the cupboard, a door that closes, predictable routines. Emotional: being accepted on the bad days and not only the good ones. Relational: knowing that telling you something difficult will not cost them their place. The approach we train our carers in, therapeutic parenting using PACE, is largely about holding those steady while a young person tries to knock them over.

Boundaries a teenager will actually accept

Teenagers do not object to rules. They object to rules that appear out of nowhere, apply inconsistently, or treat them like a nine-year-old. Carers who manage this well do something slightly counterintuitive: they hand over a share of the rule-making early, while the stakes are low. A curfew a young person helped set is one they will argue about rather than simply ignore.

• Keep rules few and plainly worded, and always explain what each one is for
• Agree them together rather than announcing them
• Make them age-appropriate: a sixteen-year-old should not have a nine-year-old’s boundaries
• Apply them consistently, including on the days you are tired
• Name trustworthiness out loud when you see it, in small ways

What to do when a rule gets broken

It will get broken. Doing something you disapprove of once, then understanding afterwards why it was not okay, is ordinary adolescence rather than a warning sign. A pattern is different, and that is what you and your supervising social worker watch for together. In the moment, the useful test is whether your response fits what happened or fits how annoyed you feel.

• Say what the behaviour was, why it was a problem, and what follows from it
• Keep the consequence in proportion, and never set it while you are still angry
• Avoid chores as a punishment: you do not want housework to feel like a penalty
• Do not remove what builds them up, such as sport, clubs or seeing friends
• Write it down and bring it to supervision, so patterns get spotted early

School and what comes after it

The teenage years are when education starts converting into options, and a steady adult makes a measurable difference here. Every looked-after child has a Personal Education Plan, and a carer who turns up to those meetings with real questions changes what gets written in them. Practical exposure beats encouragement in the abstract. Get friends and family talking about what they do for a living and what qualifications it took, because a young person who has never met an electrician cannot picture becoming one.

Mentors are worth chasing if you can find them. So is the unglamorous stuff: a quiet table, a printer with ink in it, someone who notices when coursework is due. Our article on how foster carers support children at school covers those meetings.

The conversations nobody feels ready for

Relationships, consent, sexual health, what they are looking at on their phone at midnight. Most carers dread these and most handle them better than they predicted, because the trick is not eloquence. It is frequency. Short, ordinary, slightly awkward conversations, repeated often, beat one big talk you both remember with a wince. Be honest about the gap between what young people see online and what real relationships look like, including that nobody should ever feel pressured into looking a certain way. If a subject is beyond you, say so and ask for help rather than guessing. Your supervising social worker has had this conversation with plenty of carers before you.

What happens when they turn 18

This is the question carers of teenagers ask most, and eighteen is far less of a cliff edge than it used to be. A pathway plan is written when a young person reaches sixteen, covering health, education, contact with family and money, and it is reviewed at least every six months. They get a Personal Adviser from their local authority who stays involved until they are twenty-one, or to their twenty-fifth birthday if they ask. Since 1 April 2023 the setting up home allowance in England has been at least £3,000, which is what buys the kettle and the bed.

And they may simply not leave. Staying Put lets a young person carry on living with their foster carer after eighteen, often until twenty-one. Plenty of the young people we have placed still come back for Sunday lunch years later. We have written separately about preparing a young person for independence.

What you would be paid

We say this plainly because other agencies often will not. As at August 2026, GLF pays £507.50 a week for a child aged eleven or over and £479.50 for a child under eleven, per child, for every week they are placed with you. Some placements attract an enhanced fee, generally £100 to £200 a week more, depending on the young person’s needs. It is one fixed weekly fee covering both the child’s allowance and your reward, so there are no one-off payments for birthdays to chase. Current rates are on our foster carer pay page.

You won’t have to do this alone

Nobody at GLF expects you to arrive already knowing how to talk a seventeen-year-old down at midnight. You get a named supervising social worker who knows your household properly, an out-of-hours number a real person answers, training that goes well past the basics, and other carers who have had the week you are having. Ofsted inspected us from 21 to 25 July 2025 and rated us Outstanding in all three judgements, and the part we are proudest of is what carers said about that support. There is more on the support foster carers receive from us and on becoming a foster carer.

It is completely normal to read all this and think you are not the right person. Most of our best carers of teenagers thought exactly that. You do not need to be endlessly calm, and you do not need to have raised teenagers of your own. You need to be steady, willing to hear things you would rather not, and still there in six months.

Frequently asked questions

Do I need experience with teenagers to foster one?

No. Plenty of our carers of teenagers have never parented one, and some have never parented at all. What matters more is whether you can hold a boundary without making it personal, and whether you can tolerate not being liked for a while. The Skills to Foster course and your assessment will explore that honestly with you.

Will a teenager resent being placed with me?

Sometimes, at first, and it is usually not about you. Being moved is a loss even when the move is right, and older young people have often had less say in it than they should have. It generally eases as they work out you are not going anywhere.

What if they break the rules or do not come home?

You will have agreed with your supervising social worker in advance what to do, and it will be written into the young person’s plan before anything happens. You are never deciding alone in the moment. There is a number to ring at any hour, and we would far rather you rang it early.

Do they have to leave when they turn 18?

No. Under Staying Put a young person can carry on living with their foster carer after eighteen, often until twenty-one, and many do. Their local authority also provides a pathway plan from age sixteen and a Personal Adviser who stays involved until they are twenty-one, or twenty-five if they ask.

How much would I be paid to foster a teenager?

As at August 2026, GLF pays £507.50 a week for a child aged eleven or over, per child, for every week they are placed with you, plus an enhanced fee of generally £100 to £200 a week more for higher-needs placements. It is a single weekly fee covering the child’s allowance and your reward.
