If you would like to book an appointment or telephone appointment at another GP surgery, you will need to agree to your GP sharing your health data.
You will be prompted to agree to your GP sharing your data, when you book an appointment that is not with your own GP.
You can view statements you have agreed to, by selecting "Settings", near the top of the Health App.
Then click "Statements of Consent".
If you wish to withdraw this consent, you can deselect (un-tick) the relevant consent form.
