National Referral Mechanism, London data

The National Referral Mechanism (NRM) is a framework for identifying and referring potential victims of modern slavery and ensuring they receive the appropriate support.

Raw data taken from the live management information system are available to download. New data are added quarterly, and the Home Office publishes quarterly bulletins and other reports relating to the data, available here.

The data are held by the UK Data Service, and are “safeguarded”. The tables and slides below summarise preliminary findings from analysis of London data between Q1 2021 and Q4 2025.
