Section 18 — Provisions as to reversions on assured tenancies.

(1) If at any time—

(a) a dwelling-house is for the time being lawfully let on an assured tenancy, and

(b) the landlord under the assured tenancy is himself a tenant under a superior tenancy; and

(c) the superior tenancy comes to an end,

then, subject to subsection (2) below, the assured tenancy shall continue in existence as a tenancy held of the person whose interest would, apart from the continuance of the assured tenancy, entitle him to actual possession of the dwelling-house at that time.

(2) Subsection (1) above does not apply to an assured tenancy if the interest which, by virtue of that subsection, would become that of the landlord, is such that, by virtue of Schedule 1 to this Act, the tenancy could not be an assured tenancy.

(3) Where, by virtue of any provision of this Part of this Act, an assured tenancy which is a periodic tenancy (including a statutory periodic tenancy) continues beyond the beginning of a reversionary tenancy which was granted (whether before, on or after the commencement of this Act) so as to begin on or after—

(a) the date on which the previous contractual assured tenancy came to an end, or

(b) a date on which, apart from any provision of this Part, the periodic [F1 assured] tenancy could have been brought to an end by the landlord by notice to quit,

the reversionary tenancy shall have effect as if it had been granted subject to the periodic [F2 assured] tenancy.

(4) The reference in subsection (3) above to the previous contractual assured tenancy applies only where the periodic tenancy referred to in that subsection is a statutory periodic tenancy and is a reference to the fixed-term tenancy which immediately preceded the statutory periodic tenancy.
