Modern Slavery & Child Trafficking
Understanding how children are trafficked and exploited within the UK and internationally, and how to make a National Referral Mechanism referral.
What is this?
Child trafficking involves the recruitment, transport, transfer, harbouring, or receipt of a child for the purpose of exploitation. Under international law, no consent given by a child can make trafficking lawful. In the UK, the Modern Slavery Act 2015 provides the legislative framework for identifying and prosecuting trafficking and slavery offences. Children may be trafficked for sexual exploitation, forced labour, domestic servitude, or criminal activity such as drug supply.
How it works
Traffickers may pose as family members, romantic partners, or legitimate employers. Children are moved across county or national borders and controlled through debt bondage, violence, threats, or psychological manipulation. The National Referral Mechanism (NRM) is the formal UK process for identifying potential victims of modern slavery and human trafficking and ensuring they receive appropriate support.

Prevention steps
Know how to make an NRM referral
Any first responder — including teachers, social workers, and police — can make a referral to the NRM using the online referral form via the Home Office. Referrals should be made for any child where there are reasonable grounds to believe they may be a victim of trafficking or modern slavery.
Share information across agencies
Modern slavery and trafficking cases require co-ordinated responses across police, social care, health, education, and immigration services. Use your local MASH and ensure all agencies are aware of the child's situation.
