HI I have a twelve month tenancy agreement with a break clause the company is Leaders. My first six months is up at the end of this month and would like to leave asap. Here is the break clause word for word: 1. the landlord shall be entitled to terminate this tenancy by giving notice to the tenant as follows: 1.1. the period of notice to be a minimum of 2 calender months. 1.2. the notice can be served at any time during the tenancy term but the tenancy cannot be terminated until after the first 8 months of the term. 1.3. the notice period will expire on the last day of a period of the tenancy and must be served in writing. 2. the tennant shall be entitled to terminate this tenancy by giving notice to the landlord as follows: 2.1. the period of the notice to be a minimum of 1 calender month. 2.2. the notice can be served at any time during the tenancy term but the tenancy cannot be terminated until after the first 7 months of the term. 2.3. the notice period will expire on the last dayof a period of the tenancy and must be served in writing. my question is: when is the earliest i can leave if i give notice now? i pay rent one month in advance ,can i leave at the end of feb or is it the end of march ? Any help appreciated Thanks Mark
