Thank you for your question
My name is Clare
I shall do my nest to help you but I need some further information first
Which part of the Uk is he in?
has he checked his eligibility for housing benefit?
He can check what benefits he is entitled to here
If he looses his job he will get help with his rent so it need not be the responsibility of the family.
Please ask if you need other details
You are most welcome
You can ask but site policy is that you may need to ask a separate question.
That would need a second quetsion I am afraid - there is a lot of detail involved
