How can family add money to junior isa’s.

[Abbyant]

Im probably being incredibly dense but I’ve been through all the paperwork and everywhere on their website but I can’t figure out how gp’s can add money to a Scottish friendly junior isa, there’s no account numbers to set up a direct debit and I emailed Scottish friendly over a week ago and have had no reply. Has anyone managed to set up payments from family?

My mum pays into my ds's Witham a direct debit each money, I'm sure I just gave her the account details. Also in Scotland.

So just the policy number and child’s name, because there isn’t like an account number and sort code that you’d expect with a bank account.
