Stopping a child going missing: when physical intervention is lawful in children's homes

It is late on a Friday evening and a fifteen-year-old is standing at the front door of the home, coat on, phone in hand. Staff know who is waiting for her at the end of the road. They know what happened the last time she went. Every instinct says: do not let her walk out of that door. Then the question every residential team eventually faces: can we physically stop her?

At ProActive Approaches we come to this question through #AimingForZero, the position our founder Simon Gower has held since 2016. A reduction target implies there is a number of restraints that is acceptable. Zero removes that permission, and it changes what a team asks after an incident. When a child tries to leave, the question is not only "would a hold have been lawful?" but "what did this child need from us, days or weeks before tonight, so that the front door was never the place this was decided?" Regulation 20 of the Children's Homes (England) Regulations 2015 sets the legal floor. It is not the standard we should be aiming for.

This guide is for residential staff, team leaders and registered managers. It covers what the law actually allows when a child tries to leave, why holding a child at the door so rarely makes them safer, what good prevention looks like, and how to respond when a child does go missing and when they come home.

What the law allows when a child tries to leave

Regulation 20 is short and clear. Restraint in relation to a child is only permitted to prevent injury to any person (including the child), serious damage to property, or a child who is accommodated in a secure children's home from absconding. It must also be necessary and proportionate. The third purpose applies only to secure children's homes. In every other children's home, wanting to leave is not, on its own, a lawful reason to restrain.

The Guide to the Children's Homes Regulations adds important detail. It accepts there may be circumstances where a child can be prevented from leaving, giving examples such as a child leaving to carry out gang-related activity, to use drugs, or to meet someone who is sexually exploiting them. Even then, any restraint must be proportionate and last no longer than is necessary to manage the immediate risk. The Guide also makes clear that injury includes psychological as well as physical harm.

Three points are often misunderstood:

• Restraint is wider than holding. The Guide defines restricting a child's liberty of movement as restraint. Locking an external door, removing keys, standing in a doorway to block it or disabling a child's mobility aid all fall within that definition and must be recorded as restraint.
• Deprivation of liberty needs a court. Regulation 20 does not prevent a child being deprived of liberty where a court has authorised it. Without that order, a home cannot routinely confine a child, however worried staff are.
• The test is the immediate risk, not the general worry. Staff must be able to explain what injury they believed was about to happen if the child left at that moment, why nothing less restrictive would prevent it, and why the intervention was proportionate to that risk.

That is the legal floor. A team that only asks "were we allowed to hold her?" has already missed the more important questions.

Why holding a child at the door rarely keeps them safe

Physically preventing a child leaving can feel like the most protective thing an adult can do. In practice it often achieves much less than staff hope, and costs much more.

• It buys minutes, not safety. A child who is determined to leave will usually find another moment, another door or another window. Unless the immediate danger has genuinely passed, the risk has only been postponed.
• It is physically dangerous. Doorways, stairs, hallways and vehicles are some of the worst places to hold anyone. Struggles near a door can quickly move to the floor, which is exactly where the greatest risks to breathing and injury lie.
• It can confirm what the child already believes. Many children who go missing are being groomed by adults who tell them that carers do not care, that the home is a prison, and that only the exploiter understands them. Being held at the door can seem to prove that story true.
• It damages the relationship that brings them home. The most powerful protective factor for a child who goes missing is a trusted adult they will phone, text or return to. Force at the door can close that line of contact for weeks.

None of this means staff should simply stand aside. It means the moment at the door is a poor place to make safety happen. Most of the protective work has to be done long before it.

Prevention: the work that happens before the door

The Guide expects a child's placement plan to include a strategy to minimise the risk where they may run away or go missing, and the home must have a missing child policy setting out how absences are prevented and managed. Done well, this is far more than a form. It is the team's best attempt to understand each child and make leaving less necessary.

Understand why each child goes

Children go missing for reasons, and they are rarely random. Common patterns include wanting to see family or friends, escaping conflict in the home, being drawn back to an exploitative adult or group, avoiding something they fear, or simply feeling they do not belong. Return conversations, incident records and the child's own account will usually show the pattern if someone looks for it.

Plan with the child, not about them

Ask the child, at a calm time, what tends to make them want to leave, what helps them stay, and who they would contact if they did go. Agree practical steps together: a safe word, an agreed check-in time, a staff member they trust to phone, a lift home from a friend's house with no questions asked that night. Plans the child helped write are plans they are more likely to use.

Make the home worth coming back to

Children are less likely to leave a home where they feel known, safe and wanted. Predictable routines, warm relationships, contact with the people who matter to them and a sense that staff are on their side all reduce the pull of the street. This is the same work that reduces every kind of physical intervention, which is why it sits at the heart of #AimingForZero.

Work with partners early

Where a child is repeatedly missing or being exploited, the home should be working closely with the placing authority and other agencies. Share what you know, ask for risk management meetings, and follow local protocols for exploitation and missing children. A home cannot hold this risk alone, and should not try to.

In the moment: when a child is heading for the door

When a child is about to leave, staff need a clear, rehearsed approach that keeps the relationship intact and keeps everyone safe. A helpful sequence is:

1. Stay calm and stay with them. Lower your voice, slow down and avoid crowding the doorway. A calm adult is more persuasive than a wall of staff.
2. Talk about what is happening. Acknowledge how they feel. Say plainly that you are worried and why. Offer alternatives: a walk with a member of staff, a phone call to someone they trust, a later time to go.
3. Use the plan. Remind them of what was agreed: the check-in time, the safe word, the number to call. Give them a charged phone if that is part of the plan.
4. Assess the immediate risk honestly. Is there a specific, imminent danger of injury if they leave now? Would physical intervention prevent it, or simply move it to another time and place?
5. Only then consider physical intervention. If the risk of serious injury is immediate and nothing less restrictive will prevent it, staff may need to physically intervene, using only the techniques they are trained in and only for as long as that immediate risk lasts.

If a child does leave, the response begins straight away. Follow the home's missing child procedure, keep in contact if you can, and inform the police and placing authority as your local protocol requires. Our guide to police involvement after physical intervention covers when and how to involve police well.

When a child comes home

How a home responds when a child walks back through the door shapes whether they come back next time. Lead with relief and warmth, not interrogation. Check they are safe, warm, fed and not injured. Leave the difficult conversation until they are ready.

The Guide states that the responsible local authority must offer the child an independent return home interview, and the statutory guidance on children who run away or go missing from home or care sets out what that involves. Homes should use the information from those interviews when they review risk and update plans. Avoid consequences or loss of privileges for going missing. Punishment teaches a child to stay away longer, or not to come back at all.

Recording and learning

Any physical intervention or restriction of movement must be recorded within 24 hours, and the registered person must review it. When the trigger was a child trying to leave, the record should answer the questions that matter most:

• What specific, immediate risk of injury did staff believe the child faced?
• What less restrictive options were tried first, and why were they not enough?
• Was the intervention proportionate, and how long did it last?
• What has the child said about it, and what does the team now understand about why they wanted to leave?
• What will change in the plan, the environment or the team's approach so this is less likely to happen again?

Look across incidents, not just at each one. If the same child is repeatedly held at the door on the same night of the week, the pattern is telling the team something the individual records will not.

Training that prepares staff for the door

Staff need more than holds. They need confidence in the law, skill in de-escalation and negotiation, an understanding of exploitation and trauma, and the judgement to know when physical intervention will make things worse. Training certified against the Restraint Reduction Network Training Standards must be based on a training needs analysis and put prevention first, which is exactly what scenarios like this demand.

Our physical intervention training for children's homes treats physical skills as the last part of a much larger approach, and our physical intervention training includes realistic scenarios around doors, exits and leaving the home. For our full range of support, see training for children's homes.

FAQ

Can staff restrain a child to stop them leaving a children's home?

Not simply because they want to leave. Outside a secure children's home, restraint is only permitted to prevent injury or serious damage to property, and must be necessary and proportionate. Where leaving would place the child at immediate risk of injury, such as meeting someone who is exploiting them, restraint may be lawful for the shortest time needed to manage that risk.

Is locking the front door a form of restraint?

Yes. Restricting a child's liberty of movement, including locking doors, removing keys or blocking an exit, is restraint and must be recorded as such. It must meet the same test of necessity and proportionality as any other restraint.

Should a child face consequences for going missing?

No. Consequences make children less likely to come home and less likely to tell staff where they have been. Focus on safety, warmth and understanding why they left.

Who must be told when a child goes missing?

Follow your home's missing child procedure and local protocols. This usually includes the police, the placing authority and the child's social worker, and others as set out in the child's plan.
