The three tests
The start date on Form 4A must pass all three, and it must be “the beginning of a new period of the tenancy”.
Two months’ notice: the new rent cannot start sooner than two months after the tenant has the notice (section 13(2)(a)).
52 weeks from the start of the tenancy: the new rent cannot start sooner than 52 weeks after the tenancy began (section 13(2)(b)).
52 or 53 weeks from the last increase: 53 weeks apply where 52 weeks after the last increase would be more than six days before the anniversary of the first increase (section 13(2)(c), (3A) and (3B)).
