Hi jc1
I think that this post has been input a few days ago, however I will answer once more!
It really depends what you mean by spending money. Creditors will not allow a socialising, holiday or Christmas fund, but you do need to provide for all your legitimate expenditure including medical expenses, car and house maintenance and a general provision for contingencies which I usually include at £50 per month.
The spirit of an IVA is to pay as much as you can afford, but do make sure that you are realistic with your expenditure as you have to pay for 5 years and that is a fairly long time.
