Trusted Research Environment service for England

The Trusted Research Environment (TRE) service has now been replaced by the NHS England Secure Data Environment (SDE) service.

 

Closed programme

The TRE has now been replaced by the NHS England Secure Data Environment (SDE) service. The SDE service provides access to health and social care data through a secure research analysis platform.

NHS England's Trusted Research Environment (TRE) service for England provided approved researchers from trusted organisations with timely and secure access to health and care data. Researchers were given access to their approved data (in accordance with their Data Sharing Agreements), enabling them to collaborate, link data, share code and results within the same research projects.

The service provided a secure data platform with the analytical and statistical tools to support researchers in conducting their work. 

All Trusted Research Environment users were migrated to the SDE service from 2022.  

Further information about Trusted Research Environment service customers and their research is available through the national archive.
