What to Expect from the Police: 101 vs 999
When to dial which number, what the police will and will not investigate, and what happens after you report a child safeguarding matter.
Overview
The police are part of the wider safeguarding system but their role is narrower than children's services. Their primary job is to investigate crimes, protect people in immediate danger, and gather evidence. Where a child is concerned, they work closely with children's services under joint working arrangements set out in Working Together 2023.
Dial 999 if a child is in immediate danger, a serious crime is happening now, or someone is at imminent risk of harm. Dial 101 for non-emergency matters — concerns that need a police response but are not happening at this moment, such as reporting a historic incident, sharing suspicions about ongoing behaviour, or providing information to support an existing investigation.
For online sexual abuse and grooming of a child, CEOP (part of the National Crime Agency) accepts reports through its safety centre. For child sexual abuse imagery, the Internet Watch Foundation (IWF) is the right route — they remove the material at source and pass criminal intelligence to police.
What this means in plain English
In short
Police involvement does not always mean a criminal prosecution. Often officers attend, gather information, refer the welfare side to children's services, and only progress a criminal case if there is evidence of an offence. They will keep you informed in broad terms about whether an investigation is underway.
Who is involved
- Call handler — assesses urgency and routes the call.
- Response officers — attend in person if needed.
- Police safeguarding investigation unit — handles child protection investigations.
- Children's services — works alongside police on joint visits and strategy meetings.
- CEOP — receives online child sexual exploitation reports.
- Victim support and witness care — for ongoing emotional and practical support.
What to expect
- 1
If you dial 999: an immediate decision on whether to deploy officers, and a target attendance time set by the urgency grade.
- 2
If you dial 101: a call back or attendance within hours or days depending on grading, and a reference number for follow-up.
- 3
A short interview to capture what you have seen, heard, or been told.
- 4
Evidence preservation advice — what not to delete, what to keep, and how to hand over devices if asked.
- 5
Onward referral to children's services where a welfare issue exists alongside any criminal matter.
- 6
Updates from the officer in the case, though the level of detail is limited by data protection and ongoing investigation rules.
What you can do
- Decide between 999 and 101 by asking 'is this happening now, or is someone at immediate risk?' If yes, 999. If no, 101.
- Have ready: names, addresses, descriptions, dates and times, and what was said or seen.
- Do not delete messages, screenshots, or call logs that could be evidence.
- Ask for a crime reference or incident number and the officer's name.
- Use CEOP for online child sexual abuse, the IWF for indecent imagery, and Action Fraud for financial scams targeting children.
- Ring 101 to follow up if you have not heard back within the expected timescale.
Common misconceptions
Myth: The police investigate everything to do with children.
Reality: The police investigate suspected crimes. Worries that do not involve a crime — neglect concerns, parenting capacity, family stress — are normally a children's services matter, not a police one.
Myth: Calling 101 is a waste of time.
Reality: 101 is the correct number for non-emergencies and is staffed by trained handlers. It is graded and acted on — you will receive a reference number and a callback or attendance based on the grading.
