For your security, we restrict how long the registration codes are valid, we've recently extended their validity though so if you haven't tried already, it may be worth having a go at registering to see if they still work!

If you're seeing a message that your codes have expired and you were invited by East Sussex Healthcare NHS Trust, you may request a new invitation here: 

If you were invited by another trust or organisation, please just get in touch with our support team at and let us know who invited you and we'll let you know what to do!
