Effective multi-agency data sharing is vital for public safety, yet it remains difficult to implement in practice. Fragmented systems, legal uncertainty, and cultural hesitancy complicate collaboration between police, social care, health, and other agencies—leading to missed opportunities for early intervention and increased risks to vulnerable individuals.

In this article, Capita’s lead for Justice & Policing, Dave Tonks, explores the cultural, technical, and legal barriers to data sharing. Drawing on insights from national reviews and real-world cases, it outlines how public sector organisations can shift from reactive to preventive approaches by building trust, transparency, and ethical frameworks. It offers actionable guidance on how a joined-up strategy—spanning governance, technology, and leadership—can improve safeguarding, prevent crime, and strengthen public confidence, while balancing operational and budget constraints.
