Can I rent a house from the owner and rent the rooms in the house to other people?

If the lease permits subletting. Subletting has to be WRITTEN into the lease agreement and when I worked at (mans name plus colour) for 2 years we never had a lease with a subletting clause in it. If you mean sharing a place - provided you are not making a profit, and all members are on the lease and you are under the max number of people in the flat (1 adult per bedroom + 1) then it would be OK.
