On and after the appointed day, no tenancy or licence (whenever made) can be—
a restricted contract;
a protected shorthold tenancy;
a secure tenancy;
an assured tenancy (including an assured shorthold tenancy);
an introductory tenancy;
a demoted tenancy.
If, immediately before the appointed day, the landlord under a protected or statutory tenancy might have recovered possession of the dwelling-house subject to the tenancy under Case 19 of Schedule 15 to the Rent Act 1977 (c. 42) (former protected shorthold tenancies), the tenancy ceases to be a protected or statutory tenancy on the appointed day.
Nothing in this section ends a tenancy or licence within subsection (1) or (2).
