Why MASH information sharing matters
A practical guide to MASH information sharing for safeguarding partners, providers and system leaders. Learn the governance, evidence and delivery steps that improve outcomes and reduce risk. Effective safeguarding depends on professional curiosity, robust escalation, timely information sharing and governance that turns learning into safer practice.
Understanding MASH Information Sharing
Multi-Agency Safeguarding Hubs (MASHs) were designed to improve the speed and quality of information sharing between agencies responding to safeguarding concerns. By co-locating or connecting professionals from police, children's services, health, education, probation and other agencies, MASHs aim to enable rapid, coordinated risk assessment and decision-making.
However, information sharing within MASHs remains inconsistent. Common challenges include: variation in which agencies participate and at what level, differences in thresholds for sharing information, reliance on individual practitioners rather than systematic processes, inconsistent recording and audit trails, and confusion about the legal basis for sharing (particularly under GDPR).
Better practice involves: clear information sharing agreements reviewed annually, training for all MASH practitioners on the legal framework (including the Caldicott Principles and the seven golden rules for information sharing), standardised request and response processes, regular audit of information quality and timeliness, and feedback loops so referring professionals know what happened with their referral.
The current landscape
Effective safeguarding governance requires more than compliance metrics. Boards and partnerships need to see qualitative evidence of practice improvement: supervision records that show critical reflection, audit findings that test whether policies are followed in practice, and case examples that demonstrate the impact of multi-agency working.
Safeguarding practice has evolved significantly in recent years, with a growing emphasis on contextual safeguarding, professional curiosity and trauma-informed approaches. Practitioners are expected to look beyond the presenting issue, consider the wider context of a person's life, and apply professional curiosity when something doesn't feel right — even when the individual concerned does not disclose abuse.
What organisations need to know
This article focuses on MASH Information Sharing: Common Risks and Better Practice and the wider priorities around MASH information sharing, multi-agency safeguarding hub, information sharing safeguarding. The strongest organisations do not treat this as a stand-alone exercise — they connect governance, workforce, communication and evidence so leaders can make decisions quickly and confidently.
Safeguarding partners, providers and system leaders should consider these questions before proceeding:
- What does your safeguarding supervision model look like in practice?
- How do you measure the quality of your safeguarding practice, not just the volume?
- How does your organisation support practitioners to exercise professional curiosity?
Practical checklist
Getting MASH information sharing right requires structured preparation and disciplined follow-through:
- Clarify statutory duties, thresholds, decision-making routes and escalation responsibilities
- Bring agencies together around a shared chronology, agreed risks and clear ownership of actions
- Use supervision, learning events and governance reporting to embed improvement across teams
- Translate MASH information sharing into named actions, owners and realistic deadlines
- Keep evidence, decisions and outcomes in one place so future assurance, inspection or procurement activity is easier to manage
Evidence you should have ready
Organisations with strong evidence bases consistently perform better in safeguarding activities. Key evidence includes:
- Training attendance and competency assessment records for safeguarding staff
- Case examples demonstrating effective escalation and multi-agency coordination
- Supervision records demonstrating critical reflection on safeguarding cases
Governance considerations
Strong governance underpins successful delivery. For MASH information sharing, this means:
- Multi-agency review processes with tracked actions and evidence of impact
- A named safeguarding lead with sufficient seniority and dedicated time for the role
Common mistakes to avoid
Based on our experience working with safeguarding partners, providers and system leaders, these are the most frequent errors:
- Allowing threshold disputes to delay action on clear risk
- Focusing on process completion without testing whether practice changed
- Producing action plans after reviews without tracking implementation or measuring impact
Avoiding these pitfalls requires leadership commitment, clear accountability and a willingness to seek independent review when internal perspectives may be limited.
