Before making a possession claim on an estate management ground, the landlord must give the contract-holder a possession notice specifying that ground.
The landlord may not make the claim—
(a) before the end of the period of one month starting with the day on which the landlord gives the contract-holder the possession notice, or
(b) after the end of the period of six months starting with that day.
If a redevelopment scheme is approved under Part 2 of Schedule 8 subject to conditions, the landlord may give the contract-holder a possession notice specifying estate management Ground B before the conditions are met.
The landlord may not give the contract-holder a possession notice specifying estate management Ground G (accommodation not required by successor)—
(a) before the end of the period of six months starting with the day on which the landlord (or in the case of joint landlords, any one of them) became aware of the previous contract-holder's death, or
(b) after the end of the period of twelve months starting with that day.
The landlord may not give the contract-holder a possession notice specifying estate management Ground H (departing joint contract-holder) after the end of the period of six months starting with the day on which the joint contract-holder's rights and obligations under the contract ended.
