If you want possession of your property you must serve a legally valid notice in writing. The type of notice and time scale depends on why you want a tenant to move out.
Generally, your tenant cannot give you notice to quit the tenancy before the end of the fixed term, unless:
- there is a clause in the agreement that allows them to do so;
- or you (the landlord) agree to them breaking the agreement.
Your tenant can give one months' notice to leave at the end of the fixed term. When a fixed term expires and a new one is not agreed, they can give one months' notice.
