If you wish to register a Type 1 Opt-out with your GP practice before data sharing starts with NHS Digital, this should be done by returning this form (EXTERNAL DOWNLOAD LINK) to your GP practice by 27th August 2021 to allow time for processing it. If you have previously registered a Type 1 Opt-out and you would like to withdraw this, you can also use the form to do this. You can send the form by post or email to your GP practice or call 0300 3035678 for a form to be sent out to you.
