They normally only ask for payslips, bank statements and receipts and this would not usually be every month but at review times e.g 6 months, yearly etc.
We send payslips off on a quarterly basis and have never had to send payslips or receipts.
You need to check with your own IP though as each one is different.
Sharing from experiences of dealing with debt
The greatness of a man is not in how much wealth he acquires, but in his integrity and his ability to affect those around him positively.

These days we actually encourage our clients to send us the wageslips monthly, on grounds that under IVA protocol cases there are only 14 days in which to pay over any "extras".
We have to pay our extras by the anniversary date as was one of our modifications by the main creditor. We put it away every month so we know it is there. We have to send in P60 and last three month statements and wage slips before the annual review.
