Well, I've looked at the council website and she has to fill out a form, and then have the Uni verify it. And/or go online onto a system that the Uni is supposed to have and click that she wants the credit to apply, and fill out a form, which we send to the council.
Either way, the Uni is going to have to be involved, as is the Daughter. Which is ok, we'll do what needs doing going forward. I've written to the council to ask if we could retro the status back to Sept 2017 through Nov 2018, and we'll see what they say.
