New research in the British Journal of Social Work found that Multi-Agency Safeguarding Hubs (MASHs) are associated with higher levels of child protection investigations, but not improved outcomes for children. The study analysed data from 130 English local authorities between 2010 and 2024.

Nationally, section 47 investigations rose from 89,300 in 2009/10 to 224,520 in 2023/24, while the proportion resulting in a child protection plan fell from around 50% to 28%.

Local authorities with MASHs saw steeper increases in investigations than those without them, but much smaller differences in child protection plan rates.

Researchers found no significant differences in rates of serious harm or child deaths between MASH and non-MASH areas, though they stressed the study identifies associations rather than causation.

The findings come as the Government introduces Multi-Agency Child Protection Teams (MACPTs). Lead author Andy Bilson said the research raises questions about extending similar models nationally without evidence that they improve child safety.
