Housing Benefit (UK) will being a single person in a two bed roomed house count against me?

They gonna give you some money for rent,,,if this money are enough to pay for the rent it fine,,,dont think that if u move to a smaller place and cheeaper u will have some money left couse they gonna pay u exacley the rent,,,,if u wanna move to an expensive one is fine too but u must pay the difference...
