You will get no contact from the creditors, just be assured, if they were included in the IVA ( as all unsecured creditors should have been) the debts are written off on successful completion of the IVA.
My opinions are merely that .. opinions based on experience. Always seek professional advice.
IVA Completed 23rd July 2013 .... C.C. 10th January 2014
Your credit files will begin to clear and the balances will be amended. They will show on your credit record until the 6th anniversary of the default date before they get removed. For me as soon as the money has been distributed I started to see my records be amended by creditors - some were quicker than others though
