82Security of tenure.
(1)A secure tenancy which is either—
(a)a weekly or other periodic tenancy, or
(b)a tenancy for a term certain but subject to termination by the landlord,
cannot be brought to an end by the landlord except by obtaining an order of the court for the possession of the dwelling-house or an order under subsection (3).
(2)Where the landlord obtains an order for the possession of the dwelling-house, the tenancy ends on the date on which the tenant is to give up possession in pursuance of the order.
(3)Where a secure tenancy is a tenancy for a term certain but with a provision for re-entry or forfeiture, the court shall not order possession of the dwelling-house in pursuance of that provision, but in a case where the court would have made such an order it shall instead make an order terminating the tenancy on a date specified in the order and section 86 (periodic tenancy arising on termination of fixed term) shall apply.
(4)Section 146 of the [1925 c. 20.] Law of Property Act 1925 (restriction on and relief against forfeiture), except subsection (4) (vesting in under-lessee), and any other enactment or rule of law relating to forfeiture, shall apply in relation to proceedings for an order under subsection (3) of this section as if they were proceedings to enforce a right of re-entry or forfeiture.
