As soon as practicable after a determination or re-determination has been made in pursuance of this section, the landlord shall serve on the tenant a notice stating—
The landlord shall, as soon as practicable, serve a copy of the notice on the district valuer if—
The tenant shall, as soon as practicable, serve a copy of the notice on the district valuer if the tenant requests a review of the determination or re-determination under section 128A(2)(b).
For the purposes of subsections (5A) and (5B) it does not matter whether the request in question was made before, on or after the service of the notice in accordance with subsection (5).
