For landlords and property investors, the short answer is simple only once the property, nation and agreement have been identified. In England, a landlord of an assured periodic tenancy in the private rented sector must normally give at least two months’ notice using Form 4A before a rent increase can take effect. The increase can normally happen only once in a 12-month period and not during the first 12 months of the tenancy. These rules have applied to England’s private ren

The practical answer for England: for a private-rented-sector assured periodic tenancy, a landlord must serve a completed Form 4A at least two months before the proposed new rent starts. That is only the starting point. The first increase cannot begin until 52 weeks after the tenancy began; later increases are generally subject to a 52-week rule, and the new rent must start at the beginning of a tenancy period. A rent review should protect income and protect the relationship.
