The first condition is that the landlord has served a notice of extension on the tenant at least 8 weeks before the original expiry date.
The second condition is that either—
the tenant has not requested a review under section 125B in accordance with subsection (1) of that section, or
if he has, the decision on the review was to confirm the landlord's decision to extend the trial period.
A notice of extension is a notice—
stating that the landlord has decided that the period for which the tenancy is to be an introductory tenancy should be extended by 6 months, and
complying with subsection (5).
A notice of extension must—
