Quick Answer
Map the full process first so you do not serve a notice before checking dates, evidence quality, and challenge exposure.
This hub is the control panel for the Section 13 topic cluster. Instead of treating a rent increase as a single-form task, it shows the landlord workflow as a sequence: confirm tenancy facts, calculate the earliest valid date, set a defensible figure from comparables, complete Form 4A, serve correctly, and keep the service and evidence trail ready. The practical benefit is fewer reworks, fewer avoidable disputes, and clearer internal consistency if the tenant asks for reasons or challenges the proposal.
The pages are split by intent so you can go straight to the question you actually have. One page explains the Section 13 notice role, one focuses on Form 4A completion, one clarifies rules and jurisdiction boundaries, one focuses on market-rent method, and two pages handle challenge and tribunal paths. That separation matters because these topics overlap heavily and landlords need a clear reading route, not the same content rewritten under different titles.
If you only remember one principle, use this one: serve a notice only after the underlying case file is coherent. A polished form with weak evidence is fragile. A coherent evidence file with an accurate form is durable. The Standard Section 13 wizard is designed around that order so landlords can make decisions before checkout, not discover weaknesses after service.
