Hi, this will depend on your own arrangement. Some do s final review - some just end. Mine just ended / check with your I.P and see what they need. Yearly reviews are very much down to each individual firm. I only ever needed to supply wage slips for proof of income.
A lot of companies do it to make sure that all monies have been paid across. You need to check with your IP the date of the final payment and that you cancel your DD or SO.

Once it's over, it is, last payment as confirmed by IP and then you'll hopefully come off the register within 3 months and then that completion certificate to make you officially debt free.
IVA final payment left the bank on the 26th January 2013...looking forward to a debt free future.
