For most types of tenancy agreements, it is very difficult to leave. Quite often the only way of doing this is if you find a replacement tenant for yourself if you are in a joint tenancy. It is always a good idea to speak to your letting agent or landlord as there may be a break clause in your contract with them. Failing this you may have a landlord who is willing to let you out of the contract. We would also advise that you look to advertise your room on other platforms too such as Gumtree and Spareroom. These platforms may reach a larger audience and increase your chance of finding a replacement sooner. Something to be aware of is that often when it comes to amending a housing contract, there is a fee involved. Again this should be noted on your contract and if not, you should ask your letting agent or landlord how much this will be. Further to this, you may also wish to consider what will be happening with your share of the deposit.
