I am afraid that cash in hand (which you had) going into an IVA should be declared as an asset. There is a possibility that the IP will want some, or all, of it. There is a possibility that he won't (unlikely). You can ask if you can keep some if you have essential expenses to cover (boiler blown up, car conked out) ... worth a try.
You could not mention it and keep it to yourself ... would the IP find out? Possibly .. especially when he / she gets around to claiming PPI him or herself .. in which case the IVA could be failed and flushed down the toilet !! Apart from the stress on you about whether you will get found out over the next 5 or 6 years.
My opinions are merely that .. opinions based on experience. Always seek professional advice.
