As Sprout early release loans are generally secured on property you would need to be a homeowner. However Sprout do offer unsecured lending as well, but I do not know if this would be offered to those in an IVA, as the lending risk is high, or, indeed, whether it would be acceptable to existing creditors. To be honest I would be surprised if your IP would agree, if Sprout would agree and if creditors would agree. You can but ask.
My opinions are merely that .. opinions based on experience. Always seek professional advice.
