Multi-Agency Safeguarding Hub (MASH)

Data sharing in the MASH

Section 10 of the Children Act 2004 places a duty on key people and bodies to cooperate to improve the wellbeing of children and young people. This includes the proportionate sharing of information, where appropriate, to make the best decisions for children and young people at risk.

All partners have signed up to Information Sharing Agreement that specifies what data can be shared within the MASH, and what happens to that data once the MASH Team manager makes a decision about the case. The Information Sharing Agreement is available to view.

Information Sharing Agreement

Each agency will assess whether it's appropriate for their information to be shared in line with Information Sharing Agreement on a case-by-case basis.

The data will be held securely and confidentially. The MASH will have physical, electronic and managerial safeguards to ensure that sensitive information is only accessed by those who ‘need to know’ about it.

Only relevant information disclosed during the MASH process will be passed to the non-MASH professionals receiving the case.

In some cases, a MASH worker may hold confidential information which the MASH manager need to know to make a decision, but which is too sensitive to be shared elsewhere (eg when an ongoing police investigation is taking place). In these cases, the MASH system will indicate that there's confidential information held but won't reveal the information itself.

Fair Processing Notice

We're committed to ensuring that the personal and sensitive information that we hold about about you is protected and kept safe and secure.

We have appropriate technical and organisational measures in place to prevent the loss, misuse or alteration of your personal information.

Our staff are trained how to handle confidential information and they're required to complete a refresher course annually to make sure they are working to good practice standards.

Most of the personal information you've given us won't be shared outside of the council without your consent, and will only be used to provide the service you've requested or to improve the quality of the services we're providing. However, if there are concerns that a child may be at risk of significant harm, or an adult may be at risk of serious harm, we may need to share your personal information with organisations that we work with.

We'll only share information in compliance with the law and our multi agency information sharing agreement.

You're entitled to request copies of the information that we hold about you at any time under the Data Protection Act.

We're periodically review this notice to ensure that it is up to date and reflects our current policy.

We may share your information with the organisations signed up to the Multi Agency Safeguarding Hub (MASH) for the purpose of protecting the wellbeing and welfare of children.
