The disposal by the landlord of an interest in the qualifying dwelling-house, whether his whole interest or a lesser interest, does not affect the preserved right to buy, unless—
in which case the right to buy ceases to be preserved.
The disposal by the landlord of a qualifying dwelling-house of less than his whole interest as landlord of the dwelling-house, or in part of it, requires the consent of the Secretary of State, unless the disposal is to the qualifying person or persons.
Subsection (2) does not apply to a disposal of land by a private registered provider of social housing or by a registered social landlord.

Consent may be given in relation to a particular disposal or generally in relation to disposals of a particular description and may, in either case, be given subject to conditions.
A disposal made without the consent required by subsection (2) is void, except in a case where, by reason of a failure to make the entries on the land register or land charges register required by Schedule 9A, the preserved right to buy does not bind the person to whom the disposal is made.
