Before making a possession claim on the ground in section 187, the landlord must give the contract-holder a possession notice specifying that ground.
The landlord may not make the claim—
before the end of the period of 14 days starting with the day on which the landlord gives the contract-holder the possession notice, or
after the end of the period of six months starting with that day.
This section is a fundamental provision which is incorporated as a term of all fixed term standard contracts.
