Just in case anyone is not aware of this, you can opt out of the NHS sharing your confidential personal data with other organisations for the purposes of "being used for research and planning" (believe that if you trust the government in any way, shape or form).
The deadline has been extended, it was the 23rd of June 2021 but it's now 30th of September 2021.
If you want to opt-out, here's the link. You'll need your NHS number.
