Landlord’s notice in default
125E.—(1) The landlord may, at any time after the end of the period specified in section 125D(2) or, as the case may require, section 136(2), serve on the qualifying person a written notice—
(a)requiring him, if he has failed to serve the notice required by section 125D(1), to serve that notice within 28 days, and
(b)informing him of the effect of this subsection and subsection (4).
(2) At any time before the end of the period mentioned in subsection (1)(a) (or that period as previously extended) the landlord may by written notice served on the qualifying person extend it (or further extend it).
(3) If at any time before the end of that period (or that period as extended under subsection (2)) the circumstances are such that it would not be reasonable to expect the qualifying person to comply with a notice under this section, that period (or that period as so extended) shall by virtue of this subsection be extended (or further extended) until 28 days after the time when those circumstances no longer obtain.
(4) If the qualifying person does not comply with a notice under this section, the notice claiming to exercise the right to buy shall be deemed to be withdrawn at the end of that period (or, as the case may require, that period as extended under subsection (2) or (3)).
