Emergency Housing (England and Wales)
Contact your local authority/council.
Your local council are able to give you advice and information on your situation and may be able to help you if you are homeless or about to become homeless.
Your council will have a system where they will need to class you in a specific category depending on whether you are a vulnerable person or you may have children under the age of 16 or 19 (if in full time education).
If you are made homeless following a fire or flood in your home, your first point of contact should be your local authority.
