Section 17 and Section 47: Child in Need and Child Protection Thresholds — A Practical Guide for Professionals

Professional note: Getting the threshold right matters enormously. Referring too early risks damaging family trust and overwhelming statutory services. Referring too late risks a child suffering significant harm. This guide will help you calibrate that judgement against statute and current guidance.

The Three-Tier Framework

Tier 1: Universal Services

Schools, GPs, health visitors. Child has a need that can be met through standard provision. No referral necessary. Good information sharing and monitoring.

Tier 2: Early Help / Section 17

Child in Need under Children Act 1989, s.17. Vulnerability is higher; multi-agency Early Help plan or children's services involvement without statutory child protection.

Tier 3: Section 47 / Child Protection

Reasonable cause to suspect significant harm or risk of it. Section 47 enquiry initiated. May result in child protection conference and plan.

Section 17: Child in Need

Under Section 17 of the Children Act 1989, a child is "in need" if:

They are unlikely to achieve or maintain a reasonable standard of health or development without provision of services; or
Their health or development is likely to be significantly impaired without such provision; or
They are disabled.

A Section 17 referral triggers a Child and Family Assessment, which children's services must complete within 45 working days. The outcome may be an Early Help Plan, a Child in Need Plan, or escalation to Section 47 if concerns increase during the assessment.

Examples of s.17 concerns: persistent poor school attendance linked to family dysfunction; a child with a disability whose needs are not being met; a family in acute housing or financial crisis that is compromising a child's welfare; a teenager whose home environment is chaotic but where there is no immediate risk of significant harm.

Section 47: Child Protection Enquiry

Section 47 of the Children Act 1989 places a duty on the local authority to investigate where it has reasonable cause to suspect that a child is suffering, or is likely to suffer, significant harm. "Significant harm" encompasses both the nature and extent of harm and the context in which it occurs — a single incident can meet the threshold.

Under Working Together 2023, once a Section 47 enquiry is initiated:

Children's services must lead, with police and health as key partners in a coordinated response.
A strategy discussion (or meeting) must be convened within one working day for urgent cases.
The child must be seen by a social worker, with their views taken into account (subject to age and understanding).
If the enquiry determines the child is at risk of significant harm, a child protection conference must be convened within 15 working days.

Threshold Indicators for Professionals

Consider s.17 (Child in Need) when:

• Persistent neglect without immediate danger
• Family under significant pressure but protective factors present
• Mental health or substance misuse affecting parenting capacity
• Child missing education but whereabouts known
• Parental domestic abuse but risk assessed as managed

Escalate to s.47 (Child Protection) when:

• Physical injury with unexplained or inconsistent account
• Sexual abuse disclosed or strongly suspected
• Severe or chronic neglect causing developmental harm
• Domestic abuse at high risk level (DASH RIC score)
• Child going missing repeatedly with exploitation risk
• Parental substance misuse leaving child without adequate care

Golden Rules for Referral

• If in doubt, consult your DSL — never sit on a concern waiting for more evidence
• Record all concerns, decisions and actions contemporaneously
• You do not need proof — you need reasonable cause to suspect
• Do not tell parents you are making a referral if this could put the child at further risk
• Your duty to refer overrides any request for confidentiality from a parent or child
