Hi mw and welcome to the forum
1 You are still subject to the windfall provisions until the IVA has concluded.
2 If you are going to request a formal payment break, to enable you to find work, then this can only be done with the express agreement of your creditors at a newly convened meeting to review your revised proposals.
3 If you lose your income through illness, then the IVA may have to be brought to an early conclusion. This is unlikely to result in bankruptcy proceedings against you unless you have assets which could be realised to repay creditors. Most likely, the IP will ask your creditors to accept what they have already received in full and final settlement.
4 As Ang has stated above, you then are left with the choice of bankruptcy proceedings or a Debt Mangagment Programme.
