Part I of the Leasehold Reform Act 1967 (enfranchisement and extension of long leaseholds) does not apply where, in the case of a tenancy or sub-tenancy to which this section applies, the landlord is a housing association and the freehold is owned by a body of persons or trust established for charitable purposes only.
This section applies to a tenancy created by the grant of a lease in pursuance of this Part of a dwelling-house which is a house.
Where Part I of the 1967 Act applies as if there had been a single tenancy granted for a term beginning at the same time as the term under a tenancy falling within subsection (2) and expiring at the same time as the term under a later tenancy, this section also applies to that later tenancy.
This section applies to any sub-tenancy directly or indirectly derived out of a tenancy falling within subsection (2) or (3).
