Tuition Loan Irish Citizen

Hi, I'm in the application stages for a PGCE in England, to begin in September 2025. As an Irish citizen, I'm fairly certain I qualify for home fees, and want to apply for a tuition loan. I am required to send a paper application to Student Finance England, which is asking me for details about the university I will attend, but I do not yet know which uni will offer me a place - should I just write down my first choice and then later contact Student Finance to change it? Or should I just wait until I have accepted an offer, then apply with all my details? And in this case, what would happen if I did not have a confirmed tuition loan by the start date of the PGCE? Any info would be great, thank you in advance!
