I know you can have a mortgage holiday in the case of maternity leave but what about starting a new job?

DH is going to be paid contracted as we have started our own business and won't be paid for 6 weeks, after recently being paid on a weekly basis as an emoloyee. We have some money there but I'm fretting that we won't make it because our new business comes with some pretty large expenses. We have a bit of savings but it may not be enough. We will need to make two mortgage payments in that time!
