(1)Where a tenant has the exclusive occupation of any accommodation (in this section referred to as “the separate accommodation”) and—
(a)the terms as between the tenant and his landlord on which he holds the separate accommodation include the use of other accommodation (“the shared accommodation”) in common with another person or other persons, not being or including the landlord, and
(b)by reason only of the circumstances mentioned in paragraph (a) above, the separate accommodation would not, apart from this section, be a house let on an assured tenancy,
the separate accommodation shall be deemed to be a house let on an assured tenancy and the following provisions of this section shall have effect.
(2)While the tenant is in possession of the separate accommodation, any term of the tenancy terminating or modifying, or providing for the termination or modification of, his right to the use of any of the shared accommodation which is living accommodation shall be of no effect.
(3)Where the terms of the tenancy are such that, at any time during the tenancy, the persons in common with whom the tenant is entitled to the use of the shared accommodation could be varied or their number could be increased, nothing in subsection (2) above shall prevent those terms from having effect so far as they relate to any such variation or increase.
(4)In this section “living accommodation” means accommodation of such a nature that the fact that it constitutes or is included in the shared accommodation is sufficient, apart from this section, to prevent the tenancy from constituting an assured tenancy of a house.
