Welcome to the Forum Poso,
Congratulations on your IVA being accepted, this is the start of a new debt free life.
If you are made redundant or are off sick for a period of time, you must let your I.P know. Depending on the terms and conditions of your IVA you may be allowed up to 3 payment breaks which can then be tagged onto the end of your IVA or made up by paying a little extra each month. If it is longer than this then the creditors will need to know and possibly a variation meeting held.
Check your report again, it usually states 50% of overtime/bonuses/commission but not on money that you save. If you have money left over each month you are more than welcome to save that.
Hope this helps [:D]
Best Regards,
