Hi jojo,
Bit of a bummer that your IVA is going to fail, but at least now you can move forward. You should get your certificate soon, if you don't, I'd just keep hounding your IP until they sent it to you.
Good news that at least you have an understanding landlord and have renewed your lease.
So sorry hubby hasn't got full time employment yet.
Once you get your certificate, you will be able to go BR as soon as you can get a court date.
In the meantime,you can start filling in the forms now online and save them as you go along, that way you have a head start. You can find them here:

You can come on here and ask us if there's anything you don't understand.
Good luck, and don't forget to let us know how you are getting on.
