When a fixed-term tenancy ends, you do not necessarily have to leave, particularly if you have been renting for six months or more and Part 4 tenancy rights apply. In that situation, the landlord generally needs a valid legal ground and must serve a correctly completed Notice of Termination with the required notice period. You do not usually have to sign a new lease for the tenancy to continue, although the original terms may be reviewed. Your rights depend on the tenancy’s length and agreement, so check the RTB guidance or seek advice from a qualified housing solicitor if the landlord asks you to leave.
