Rent Increases: The Notice, the Dates and the Proof
A rent increase is only as good as the records behind it: the right notice, served correctly, with dates you can prove. What landlords should keep at each step.
Rent increases go wrong on process far more often than on amount. A notice sent too late, to the wrong address, in the wrong form, or with no proof it arrived can leave a landlord charging a rent the tenant is entitled to refuse. The rules on how often rent can rise, by how much, how much notice is required and what form the notice takes vary widely between countries and even between tenancy types, so check your jurisdiction and the tenancy agreement first. Whatever the rules, the records you need are much the same.
Before the notice: know your basis
- The clause or rule you are relying on. Does the agreement contain a review clause? A fixed formula, such as an index? Or does the increase need agreement or a statutory procedure?
- The earliest date an increase can take effect, given the tenancy start date, any fixed term and the date of the last increase.
- How you arrived at the figure. Comparable rents, index values on a named date, or the formula in the agreement. Keep the working, not just the result.
The notice itself
Record exactly what was sent: a copy of the notice as issued, the old rent, the new rent, the effective date, and the addressee and address used. If a prescribed form applies, keep the version you used. Generating the notice from the tenancy record, rather than retyping names and figures into a letter, removes the most common errors: a wrong unit, a misspelled tenant, an effective date that does not match the calculation.
Service: prove it arrived
How the notice was delivered matters as much as what it said. Keep evidence of the method used and the date: a signed receipt, recorded delivery confirmation, a dated photo of hand delivery, or an electronic signature or read record if electronic service is permitted. Note the date the notice counts as served under the applicable rules, which may differ from the day you sent it. We covered the general principles in proof of service and delivery records.
The dates that matter
| Date | Why you need it |
|---|---|
| Last increase took effect | Many rules limit how often rent can rise |
| Notice served | Starts the notice period |
| New rent takes effect | When the higher amount is first due |
| Any response or challenge deadline | When the tenant can dispute it, if they can |
| Next possible review | So the next cycle starts on time |
After the increase
Update the rent schedule from the effective date, not from the date you remembered. Check the first payment at the new amount arrives and chase any shortfall promptly and in writing. If the tenant agreed in writing or challenged the increase, file that response with the notice.
Keeping it in one place in Herarx
On a tenancy case, the rent, the last increase date and the next review date can be typed fields with tracked dates that appear on the calendar. A template document can generate the notice from those fields, it can be sent for e-signature where that suits, and the signed copy is filed back on the case. A template rule can ask a named person to approve the new figure before it takes effect, which is useful where an agent proposes and an owner decides.
