If job prospects are not good in your area or in your field of expertise then it could turn out to be inevitable. You should also consider how long you have been in the IVA and how much, if any, redundancy payment might be received.
As John says there are a number of factors to consider.
It is worth speaking to your IP to advise that there is a problem regarding employment. This should put things on hold for a few months while to review other employment.
It might be worth exploring all the other options before going Br as you are already down the IVA road.
