Gov.UK have the following available:
If you have a medical condition which makes you extremely vulnerable to coronavirus (COVID-19), register and tell us whether or not you need support.
You may have received a letter from the NHS telling you that you’re clinically extremely vulnerable, or been contacted by your GP or hospital clinician. If this has not happened by Monday 30 March, contact your GP or clinician after you register with this service.
It may take time for any support offered through this service to arrive. Wherever possible you should continue to rely on friends, family and wider support to help you meet your needs.
You can register yourself, or on behalf of someone else.
