If it appears to a local housing authority that the interest of a person eligible for assistance in respect of a defective dwelling in their area is—
the authority shall prepare and submit to the Secretary of State a scheme providing for the provisions of this Part to have effect, in their application to such a case, subject to such modifications as may be specified in the scheme.
A scheme under subsection (1) above shall not have effect unless approved by the Secretary of State; and any such approval may be made conditional upon compliance with requirements specified by him.
In this section "shared ownership lease" means—
The fact that a lease becomes a shared ownership lease by virtue of . . . a determination under subsection (4)(d) does not affect the operation of the provisions of this Part in relation to a case where an application for assistance under this Part has previously been made.
