Hi nb
It will depend upon the attitidue of yoir individual IP as to whether your husband's shift allowance should be included. If it is received regularly and is contractual, then it should be included in both an IVA and a DMP to be frank. If it is not regular, and cannot be relied upon, then it is probably best left out.
In my experience Welcome Finance are generally supportive of IVAs, and as they have such a small debt compared to your others can probably be outvoted in any case.
You can carry on with your Christmas Club, providing the monies are paid into a completely separate bank account in the name of the club. These monies are trust monies and would not be affected by any form of insolvency.
