Hi Tigwig,
I really hope he finds work soon.
As I pointed out, find out what the shortfall is and whether paying it will get him JSA.
There is another problem with not enough NIC and it's your state pension. Get a forecast and get in contact with NIC.

I know pensions are forever away but if you're short???? you won't get a state pension either.
Also, if your husband became ill he wouldn't be entitled to incapacity and it would all fall on our shoulders.
Don't give up!!!!
