Modern slavery assessment tool

The Home Office has developed a Modern Slavery Assessment Tool to support public bodies to assess their own supply base for modern slavery risks.


The MSAT is a modern slavery risk identification and management tool. This tool has been designed to help public sector organisations work in partnership with suppliers to improve protections and reduce the risk of exploitation of workers in their supply chains. It also aims to help public sector organisations understand where there may be risks of modern slavery in the supply chains of goods and services they have procured. Public sector organisations are encouraged to use the MSAT with existing suppliers.

The tool asks suppliers questions about the processes they have in place for managing modern slavery risks and provides automated recommendations on how to improve their anti-modern slavery processes.

If you are a public sector buyer that wants to invite your suppliers to complete MSAT, find out more.

There is also guidance available for public sector organisations to support them in further discussions with suppliers on their results.

To use the assessment tool you must first register as a Buyer via the Supplier Registration Service. Once you have registered as a Buyer you will have access to the Evaluator's guidance. You will be able to invite suppliers via the Manage category link on the Suppliers tab of your Buyer dashboard.
