Data Uses Registers

The Data Uses Registers are published every month and provide information on our external Data Sharing Agreements. They are supplemented by the Internal Data Flow Record that provides information on data sharing internal to the organisation.

Due to the merger of NHS Digital and NHS England on 1 February 2023, the Data Uses Register reports will no longer include data sharing agreements within NHS England from that date.

Instead, the Internal Data Flow Record will provide information on data sharing internal to the new merged organisation. Find out more about the merger.

We have developed reports, now published in beta to allow easy navigation. There are two reports that can be used to interrogate each Data Sharing Agreement (DSA) for further details, such as:

  • the start and end date of the DSA
  • the organisation name(s) of the data controller(s)
  • whether the data controller(s) are sole or joint controllers
  • the purpose for which the data was provided
  • information on the data sets approved
  • the legal basis under which data is released
  • if they have permissions to onwardly (sub-license) share the data
  • if the application is for a commercial purpose
  • whether patient opt-outs* were applied to the data set before release
  • details of physical files that were released and when.

As this is the first version of the Power BI Data Uses Register, we welcome any feedback. Feedback can be sent to [email protected], with the subject: Data Uses Register Feedback.

In addition to the Power BI reports, we publish an .xlsx version of the Data Uses Register to meet accessibility standards.

The Power BI reports include all DSAs active from January 2020. For previous DSAs please see our release register archive.

*Our patient opt-out policy explains when opt-outs do and do not apply in more detail.

**The applicant organisation of a DSA is the organisation that submits the application to NHS Digital and is not always the organisation receiving or determining the purposes and means by which the data are processed.

The data controlling organisation determines the purposes and means by which the data are processed.

The reports above are in Microsoft Power BI which does not fully support all accessibility needs. If you need further assistance, please contact us for help.
