Maintenance loan payment dates

Hi, I have applied for finance and the application has been approved and the status says payment scheduled. The first payment is scheduled for the 23rd Sept which is the start of the induction week .I enrol at uni Next Monday (19th Aug) I have read that you get paid a few days after you enrol? So is there a chance I might get paid a few days after I enroll as I has got to buy some equipment.Thankyou
