Multi Agency Safeguarding Hub (MASH)

What is the Multi-Agency Safeguarding Hub?

The Barnet MASH acts a single ‘front door’ for children in need of additional support and/or protection. Co-located within the MASH is a partnership of professionals from a range of agencies including the police, health, education, children’s social care, children’s early help, substance misuse, housing, probation and domestic violence services.

The professionals work together to share and analyse information held on multiple client data systems to build a picture of the child’s history, current circumstances, support systems, needs and risks, so that proportionate and timely decisions can be made about the type and level of services children need to safeguard their welfare, meet their needs and improve their outcomes, ensuring that children receive the right help first time.

Barnet MASH aims to ensure that:

  • All safeguarding referrals are dealt with in a timely and effective manner to ensure the immediate protection of children
  • Decisions are timely, sound and based on high quality multi-agency information sharing arrangements
  • All agencies have the confidence to share information safely and securely
  • Risk is identified through robust analysis of a wide range of historical and current information and concerns
  • Children, young people and their families are referred to the right services first time and as early in the life of the problem as possible
  • Professional agencies working with children and their families have access to information that is proportionate and relevant to their involvement in a child’s life
  • Allocation of resources for children and families is timely, coherent and transparent
  • Professionals / Practitioners have rapid access to qualified and experienced social work professionals for safeguarding advice, information and guidance on access to local resources
  • The service is well understood and accessible to those that need it
  • Our partnership arrangements are continually reviewed and built upon to improve access and promote seamless delivery throughout the borough

How do I refer?

Before making a referral please consult the Continuum of Need and Support. You will need to consider if the child or young person‘s needs can be met by services from within your own agency, or by other professionals already involved with the family.

In order to make a referral you will need to complete a referral form. You will then receive an acknowledgement email from the MASH with a reference number.   

It is your responsibility to discuss this referral with the family. If you feel that by doing so this child would be placed at risk of harm, or you have any further questions please contact the MASH team on 020 8359 4066. (link to main website)
