Check your rental agreement
Firstly, before you even think about looking up new suppliers, you need to check your rental agreement to make sure that you’re the one in control of the utility bills and not your landlord. Some student homes come with all bills included, or the landlord has stated in the contract that they’re to decide which suppliers you use. If this is the case, you won’t be able to change suppliers without speaking to the landlord and gaining their permission first.
Other things you should look out for in the rental agreement are if the landlord has requested that you tell them of any supplier changes, or if the agreement has a notice and returns clause. A notice and returns clause simply means that when you switch suppliers, you need to inform the landlord, and once you move out, you need to switch back to the original provider.
