You need to put in your roll number, quite often in these cases the sort code and acc no are generic ie everyone uses them as a holding area, your roll number will identify you. ie with a gas bill you would put in your gas acc no.

I usually put in the persons name and the bank name in the reference field. (Unless it requires a roll number or equivalent).

That's just me wanting to be doubly sure it goes to the right person!
