I have tried filling out the forms on the UK health Surcharge fee Portal as a dependant with 3 young kids wanting to join my hubby who has been in the UK since October, 2014 for his PhD , but the forms here seem quite confusing. Please can someone explain it?
I still have some reservations about this portal.

Who is the lead applicant and main applicant

1)When one is Lead applicant, you can only add a Main applicant but not DEPENDANTS.

2) When one is a Lead applicant and adds dependants, you cannot add a MAIN APPLICANT

3) The start date of course does not accept any other date before April 6th 2015
