Student finance apllication is still ongoinn

I'm really worried about my applicatin. I still have evidece to provide becuse I'm applying through long residency. So I have to wait for my secondary school to open to request a letter for them to basically say I studied there for 5 years. That's basically all I need and my secondary school starts on the 5th and hopefully I'll be able to post is by the 10th to SFE. Will I need to contact my uni to let them know what's happening? Will I have to pay for part of my tuition loan? Will I have to repeat this next year? Because honestly this application process ruined my summer and if I have to repeat it...

Contact the student records/finance department at your uni to advise them that your tuition fee loan might be delayed. You do reapply each year (from around March), but as you won't need to prove residency again it should be a far simpler process for you.

Will I have to pay at all? Because I’m doing my online enrolment for my uni (Reading) and it says that if my loan arrangements are not confirmed by the 13th of October I will have to pay it in full?!
