I had a particularly hard time trying to find the actual site where you can log in to see which school your child has been allocated so thought I would post it here to help any others struggling.
this is the site:https://one.southend.gov.uk/CCSEnterpri ... ccount.mvc
I believe that you can log in any time after midnight on Sunday
This address is only for Southend on Sea residents, though - Essex CC residents log in to the Essex site, even if they have only applied to SBC schools (and vice versa
Good luck for Monday
