How you can request access to NHS SDE Network
To access SDE Network data, users must first be validated by the SDE Network. This validation process is currently in its pilot phase, with the full service expected to be operational by October 2025. In the meantime, if you would like to be added to the list for validation once the service goes live, please email england.data.healthresearch@nhs.net
