If you previously registered an Eastern England Secure Data Environment opt out and now wish to opt back in you can do this using one of the three methods listed to the right. Your data will be used for research taking place within the Eastern England SDE once we have received confirmation that you want to opt back in. It may still have been used for other applicable research while you opted out, for example, research using your data through an SDE in another region.

The Eastern England SDE opt in will apply to research projects that occur from the point of opt in, but will not apply to projects that took place before the opt in was registered.
