If you have signed an open ended tenancy agreement, this means you have one month's giving notice period, when you want to move out. Please read the terms of the tenancy agreement! If you have signed a fixed term tenancy agreement, the agreement is valid for the specific period defined in the tenancy agreement and there is no need to give notice to a fixed term tenancy agreement.
