Housing / Child Tax Credits etc

Hi All

Wonder if any one can help.

I have my own place (rented) with my younger brother. My brother is a student with no job and so I currently obtain housing benefit (small amount as work full time) and child tax credits and benefit as I am guardian.

My brother will be soon moving to uni and living at their dorms during the week but will still be registered at my address as his main address. Do I still receive those benefits?

I am trying to find out so if I need to arrange for lodge etc. Any help will be really helpful !!
