Hi again fiona
If you change jobs and your income reduces, causing you to need to reduce your IVA payments, then this can only be done via a formal variation of the IVA terms. Your IP will need to call another meeting of creditors for them to consider a revised offer.
I would not encourage bankruptcy proceedings at this stage, as you have three years left to pay and will likely have to pay the same amount in your bankruptcy. Doesn't seem worth doing, but you could keep it up your sleeve if creditors reject your proposed variation.
