What is the difference between "all bills included" and "utility?
Utility bills would generally only be gas, electric, and water, and - where applicable - any service charges on a leasehold property. Non-utility bills would be council tax, telephone/broadband/cable, etc. That you are a student and not actually eligible to pay council tax may not necessarily benefit you, because it depends entirely on the set-up. You say "renting a house," but I find it hard to believe you as a single person and a student would be doing that in London, so will assume you are talking about a house-share or bedsit in a larger property. If everyone in the property is a student, then no council tax will be due, but if two people are not students, full council tax will be due. If the landlord is only renting to students, then the rent will be on the basis of no council tax being due. If it is a mixture of students and non-students, you personally being not liable to council tax is not going to get you a "discount," because the landlord's not going to be getting one from the council.
