I completed my IVA from Grand Thorton and got my IVA closure certificate 2 years ago. Just recently I have a claim from my PPI and they told me all the money will go to the creditors.
This is correct, the PPI will be deemed to be an asset of your IVA even though your IVA has concluded, however you may be entitled to the interest that was paid along with any refund of PPI premiums
