Logging in 

  • Each time you login, you will need your email address and password.
  • Ensure you type your email address in, do not let your computer autofill as this will sometimes put in extra spaces and cause it to fail.
  • Make sure you click the Essential Cookie Consent slider.



The first time you log in, you will be asked to enter your basic profile questions.

  • Participant name will appear on your cards and letters, although you can change this when you create them
  • Preferred ID Card Language will default to the chosen account language, but can be changed if you want a different language card or letter.
  • We ask your Birth month and year in order to group participants by age groups, for analysis.
  • Biological sex is asked rather than gender identity because some diseases, medications and treatments affect men and women differently.
  • Your Height and Weight will help our researchers to see where diseases disproportionately affect a particular weight category.
    We have provided height and weight conversion charts for you to approximate your weight and height in the required dimensions.



  • Your Body Type helps us to categorise you for data analysis, where required.
  • Blood group can sometimes be a factor in how a disease affects you, so it is important to know this. 
    If you don't know your blood type, there are kits you can buy to test it at home. If you don't want to tell us, choose P (private)



  • Covid-19 Vaccination - if you have had a Covid injection, you will be reminded to add it to the Vaccinations section.
    It is essential to this study, that we know your Covid vaccination status.
  • Covid Swab test - this question is to ensure we capture those people who have never had a Covid Swab test.
  • Data usage consent is required for every household participant (or their legal guardian, if under 16).
    Please note that the image below is incorrect - the data consent reads:

I understand that my Health Data as provided, will be anonymously included within the Control Group Health Database which may be made available to researchers, scientists and doctors as well as fellow participants of the Control Group for our mutual benefit.

For records other than my own, I confirm that I have full consent to manage the data for this participant, or, if the participant is under the age of consent, that I am their legal parent or guardian.



  • Click the Register button to complete your record. You will be taken to your new Dashboard.
