Troubleshooting: NHS001 error guide

The most common causes of an NHS001 error:

We will be happy to help you switch to your new GP surgery, on the Health App.

Simply, submit a support ticket to us, with the information below:

  • Old GP surgery:
  • New GP surgery:
  • Has your new GP surgery confirmed that you are now registered on their clinical system/records? Yes/No
Here is more information about changing your GP surgery:

B. Have an existing Classic login

As of 1st June 2022, patients will only be able to log in to the Health App using NHS login details.

If you previously signed-in with our Classic login and did not migrate your Classic login method to NHS login, you can continue to use your Health App account by selecting the blue 'Continue with NHS login' button, and following the on-screen instructions to apply for an NHS login account, or login with an existing NHS login account.

If you use a mobile phone number instead of an email address for your Classic login, please remember that you will need to use an email address when setting up your NHS login.

After the you have applied for an NHS login account or have signed-in with an existing NHS login, all of the Health App features that you could access before, will become available again.

If you wish to continue to use the Health App, with the same login details you were using with our Classic login method, the following steps will guide you through this process:


Step 1: Select the blue 'Continue with NHS login' button.



Step 2: You will then be taken to the NHS login screen. Follow the on-screen prompts (provided by NHS login) to sign-in with an existing NHS login account, or register for a new NHS login account.






Here is more information about migrating your Classic login method:

If you are still seeing an NHS001 error code, any other error code or still having problems with your Health App account, please get in touch with our support team.


C. You are using one email address for two Health App accounts, and wish to migrate your Classic login method to NHS login

If you share your email address with another Health App account, for another person (e.g. your spouse), you will need your own individual email address and phone number for NHS login, as NHS login provides a higher level of security.
