Guidance
How rent increases usually work
Form 4A is commonly used to propose rent increases for many assured periodic tenancies in England. It should be completed accurately and served correctly.
As a rule of thumb, landlords usually allow at least two months between service and the proposed effective date.
Where a previous increase exists, timing should usually be checked against the 52-week rule to reduce avoidable errors.
