This Chapter applies to premises if—
they consist of a self-contained building or part of a building, with or without appurtenant property,
they contain two or more flats held by qualifying tenants, and
the total number of flats held by such tenants is not less than two-thirds of the total number of flats contained in the premises.
A building is a self-contained building if it is structurally detached.
A part of a building is a self-contained part of the building if—
it constitutes a vertical division of the building,
the structure of the building is such that it could be redeveloped independently of the rest of the building, and
subsection (4) applies in relation to it.
This subsection applies in relation to a part of a building if the relevant services provided for occupiers of it—
are provided independently of the relevant services provided for occupiers of the rest of the building, or
could be so provided without involving the carrying out of works likely to result in a significant interruption in the provision of any relevant services for occupiers of the rest of the building.
Relevant services are services provided by means of pipes, cables or other fixed installations.
Schedule 6 (premises excepted from this Chapter) has effect.
