Do you need a spare bedroom to foster?

More people talk themselves out of fostering over a bedroom than over almost anything else. They walk down the hall, count the doors, decide the answer is no and never make the call. That is a shame, because the actual requirement is narrower than the phrase “spare bedroom” makes it sound, and there are more ways to meet it than most people realise.

The short answer

In almost every case, a child who comes to live with you will need a bedroom of their own. That is not the same thing as owning a permanently empty room with a made bed in it, waiting. The room can be your home office, or the place the ironing board lives, so long as it can become a proper bedroom before a child arrives. What we are looking for is a room that will be theirs, with a door that closes and somewhere to put their things.

The exception is a baby. At South Coast, a baby under two can sleep in a cot in your own room, so a spare bedroom is not always the deciding factor for baby fostering. The Lullaby Trust advises that babies sleep in the same room as the adult caring for them “for at least the first six months”, which is exactly how most new parents do it anyway.

What the rules actually say

The requirement comes from Regulation 26 and Schedule 3 of the Fostering Services (England) Regulations 2011, and it is spelled out in the government’s National Minimum Standards for fostering services. Standard 10 covers the physical environment, and the sentence everyone wants is 10.6: children over the age of three should have their own bedroom, and “if this is not possible, the sharing of a bedroom is agreed by each child’s responsible authority and each child has their own area within the bedroom.”

Two other lines matter as much and get quoted far less. Standard 10.1 says the home must “comfortably accommodate all who live there”. Standard 10.2 says it should be “warm, adequately furnished and decorated” and kept clean and in good order.

Read those together and you get a fair picture of what is being asked. Nowhere in the standards is there a square footage, a minimum window size or a rule about built-in wardrobes. Nobody measures your carpet. The test is whether a child can live comfortably in your home, which is a judgement made by a person who visits, not a number on a form.

Which rooms count, and which don’t

A box room counts, as long as a single bed and somewhere for clothes fit in it without the door hitting the bed frame. Plenty of children in care have had a small room and loved it, because it was the first room that was properly theirs.

A loft or garage conversion counts if it was done properly and signed off. If it wasn’t, the fire safety questions come before the bedroom questions, and your assessing social worker will say so early rather than at the end.

A dining room with a sofa bed in it does not count, and neither does a through lounge with a curtain across the middle. A child needs to be able to shut a door on the rest of the household.

One more thing worth saying: do not decorate it first. New carers often paint the room grey and buy a duvet set before they have been approved. Children arriving in a strange house have had almost every choice taken away from them that week. Letting them pick the paint colour, or at least the bedding, gives one back.

If you rent, or live in a flat

You can foster in a rented home. Owning your house has never been a requirement, and a flat is fine if it has the space and the garden or park access a child needs. What we will talk about is whether your tenancy is reasonably secure, because a child who has already moved several times should not be moved again in six months, and whether your landlord knows.

There is a benefits point here that catches people out in the other direction. If you claim Universal Credit and get help with housing costs, approved foster carers are allowed one extra bedroom in the size criteria, and Turn2us confirms you can still get it “even if you do not have a foster child living with you at the moment”. It is one extra bedroom, however many children you are caring for.

Please note: this is general information, not personal advice, and the benefits rules described here are those in place in 2026. Your own entitlement depends on your circumstances, so check with a benefits adviser or at Turn2us before you count on it.

What actually happens when someone comes to look

The home safety check is less frightening than it sounds. Somebody walks round your house with you, gets down to a child’s eye level and points at things:

• window restrictors upstairs
• a stair gate if a child under five is coming
• hot water no higher than 43C at the tap
• medicines, cleaning products, matches and sharp knives out of reach or locked away
• a working smoke alarm on every floor
• a pond covered or fenced off

Most of it is a Saturday afternoon and a trip to a DIY shop. Where something bigger is needed, you will be told what it is and given time to sort it, not turned down on the spot.

After approval, the standards require your home to be inspected once a year by the fostering service without an appointment. Carers tend to dread that idea and then find it is a cup of tea and a look round. Nobody expects a show home. They expect a family home that is safe.

Why an empty room is worth more than it was

Ofsted’s most recent figures put the number of fostering households in England at 42,190 as at 31 March 2025, down again on the year before and falling for the fourth year running. The Fostering Network has estimated that around 6,500 more fostering families are needed across England for every child to live with the right family.

Behind those numbers is something local. When no approved home is free nearby, a child moves away from the school they were doing well at and the friends they had. A spare room in Southampton or Bournemouth is not an abstract asset. It is the difference between a child staying at their school and a child starting again.

You won’t have to do this alone

If you are reading this and mentally measuring the small room at the back, that is exactly the point at which to talk to somebody rather than guess. Our team will tell you honestly whether what you have works, and if it doesn’t yet, what would change that. You can see what the rest of becoming a foster carer involves before you commit to anything.

Everything after that comes with support from our team: a supervising social worker who knows you and your household, the Skills to Foster course before your first child arrives, training as you go, and other carers nearby who have done all of this. Foster carers do not wear capes. They have a room, some patience and a phone number they can ring at three in the morning.

The room is also paid for. South Coast pays £479.50 a week for a child aged ten and under and £507.50 a week for a child of eleven and over, as a single weekly fee covering the child’s costs and your professional fee. A child isn’t just given a home, they’re given a chance.

Frequently asked questions

Do I need a spare bedroom to foster?

For a child over the age of three, yes, you need a bedroom that can be theirs. It does not have to be sitting empty now, and it does not have to be large. For a baby under two, a cot in your own room can be enough.

Can two foster children share a bedroom?

Sometimes, but it is not the default. The National Minimum Standards allow it where the child’s responsible authority agrees and each child has their own area in the room. The fostering service has to weigh what has happened to each child before and what the children themselves want, then write down how the decision was reached.

Is there a minimum bedroom size for fostering?

No. There is no square footage anywhere in the fostering standards. The room has to accommodate a child comfortably, which is assessed in person by your social worker rather than measured.

Can I foster if I rent my home?

Yes. Owning your home has never been a requirement. Your assessment will look at how settled your tenancy is and whether your landlord is aware, and approved foster carers claiming Universal Credit are allowed one extra bedroom under the size criteria rules.

Can my foster child share with my own child?

It can be agreed in some circumstances for children under three, but for children over three the standards expect each child to have their own room. It is a conversation to have early, because it shapes which children we could ask you to care for.
