Rent Increase Notice Template — wording, delivery and timing
Raising rent is two jobs, and most landlords skip the second one. The first is getting the number right. The second is putting that number in front of the tenant in a form that can be proved later. A correct number delivered badly turns into an argument three months down the line.
This page covers the second job: the wording to send, how to choose a delivery method, and what the notice is worth if the tenant refuses to accept it.
If you have not settled on the number yet, start there: how to calculate a rent increase.

Check your local rules first
Rent increases are governed locally, and the rules differ more than people expect. Depending on where the property sits, some combination of these will apply:
- A minimum notice period. Commonly 30, 60 or 90 days, often scaled to the size of the increase or the length of tenancy.
- A cap on the increase. Some jurisdictions cap it, some tie it to an inflation index, most have no cap at all outside rent-stabilised stock.
- A required delivery method. A few places specify how notice must be served, and a notice served the wrong way can be void even when the amount is lawful.
- A frequency limit. Often no more than once in any twelve-month period.
Nothing below overrides those rules. Check them before you send, because a notice that ignores a local requirement fails on procedure regardless of how reasonable the number is.
Why a verbal notice is not enough
If you get on well with your tenant, mentioning it in conversation feels natural. The problem is that a conversation proves nothing six months later.
A written notice does three things:
It fixes the date. The period the increase applies from is documented. “I told you back in February” and “our notice dated 15 February” are not comparable as evidence.
It fixes the amount. Numbers get misremembered after a verbal exchange. In writing, the old rent, the new rent and the difference are each stated separately.
It demonstrates good faith. If the matter ever reaches a tribunal or court, the party who gave proper notice on time is in the stronger position.
The seven elements a notice needs
- The parties: landlord and tenant, full names
- The property: full address, including unit number
- The tenancy: the date of the lease or tenancy agreement
- Current rent: the monthly amount being paid today
- New rent: the monthly amount after the increase, and the percentage applied
- Effective date: the month from which the new amount is due
- Date and signature: when the notice was issued, signed by the landlord
All seven fit on one page. Length does not strengthen a notice. It only adds sentences that can be argued about.

NOTICE OF RENT INCREASE
Dear [Tenant Name],
This notice concerns the property at [full address], let to you under the tenancy agreement dated [dd/mm/yyyy].
The monthly rent will be adjusted as set out below, effective from the start of the rental period beginning [dd/mm/yyyy].
Current monthly rent: [.....] Increase applied: [.....]% New monthly rent: [.....] Effective from: [dd/mm/yyyy]
The new amount applies to rent due on and after the effective date. The payment date and payment method remain unchanged.
Please retain this notice with your tenancy documents.
[Landlord Name] [Date] [Signature]
The wording is deliberately plain. Adding a justification paragraph, a market comparison or a personal explanation does not strengthen the notice; it opens new ground to dispute.
Delivery method: what each one actually proves
This is the part most guides leave out. Three methods, three different evidentiary weights.
| Method | What it proves | Cost | When it is enough |
|---|---|---|---|
| Hand delivery, signed for | That the tenant received the document | Free | Good relationship, tenant will sign |
| Tracked or recorded mail | That an envelope was sent and delivered | Low | Tenant reachable, but signature unlikely |
| Notarised or process-served | The content, the sending and the service | High | Relationship strained, dispute expected |
The distinction matters. Tracked mail proves an envelope arrived. It does not prove what was inside it. If a tenant claims the envelope held something else, the postal record will not contradict them. A notarised or formally served notice puts the text itself on record, which is why it carries the most weight.
The practical rule: hand delivery with a signature is fine when the relationship is normal. If the tenant has been difficult about payments before, or you expect a challenge, go straight to the formal route. The cost difference is small next to the cost of a contested period.
When delivering by hand, print two copies. The tenant signs one as received and that copy stays with you.
Timing
The notice must reach the tenant before the new period begins, and by at least the minimum notice period your jurisdiction requires. Late notice creates two problems: the tenant cannot plan, and the service date risks falling after the effective date, which can invalidate the increase entirely.
A sensible habit is to send it one full period ahead of the legal minimum. That gives the tenant time to prepare and leaves room for postal delay.
Tracking renewal dates is a job in itself once you hold more than one property. The method is here: how to manage multiple rental properties.
Six mistakes that make a notice contestable
Omitting the percentage. Stating only the new amount is weaker than showing the calculation. With the percentage written down, the arithmetic is transparent and “where did that number come from” is answered before it is asked.
A vague effective date. Write the actual date, not “from next period”. Vague wording invites a dispute about which month the first increased payment covers.
Ignoring the notice period. This is the most common way an otherwise reasonable increase fails. The amount can be lawful and the notice still void because it arrived too late.
Treating it as a new tenancy. A rent increase continues the existing agreement. Asking the tenant to sign a fresh lease reopens every other term in it.
Agreeing verbally and never writing. Even where the tenant has already said yes, send the notice. Acceptance is not a record.
Keeping only one copy. For hand delivery, two copies is not optional. Without a countersigned copy you cannot prove what you served.
If the tenant refuses
A notice is not an offer requiring acceptance. If the tenant does not sign, the notice still stands provided it was properly served. Service is what matters, not agreement.
If the tenant keeps paying the old amount, the shortfall accumulates. Your notice is the document establishing the date the shortfall began. Without it, that claim is far harder to make.
This is where payment records earn their keep: if you cannot show which month came up short and by how much, you cannot state the amount owed with any precision. The method for keeping those records is here: how to track rent payments, and a ready-made sheet is here: rent tracker Excel template.
In short
Put it in writing, include all seven elements, state an explicit effective date, and pick the delivery method that matches the relationship. Two copies for hand delivery, formal service when a dispute is likely. Send it early enough to clear your local notice period with room to spare.
Those four habits turn a rent increase from a negotiation into a routine administrative step.
Frequently asked questions
Does a rent increase notice have to be notarised? Usually not. Hand delivery with a signature or tracked mail is accepted in most places. Formal service records the content of the notice as well as its delivery, which is why it is worth the cost when you expect the tenant to challenge the increase.
Is the increase void if the tenant refuses to sign? No. The notice does not depend on the tenant’s agreement. If they will not sign, serve it by tracked mail or through a formal process. Proper service is what counts.
How far in advance should I send it? Before the new period begins, and by at least the minimum notice period that applies where the property is. Sending one full period earlier than the minimum is a good habit.
Do I have to state the percentage? It is rarely required, but it is worth including. Showing the percentage makes the calculation transparent and removes an obvious line of argument.
We agreed verbally. Do I still need to write? Yes. A verbal agreement is not a record. If the amount or the date is disputed months later, you need something in writing to point to.
Should we sign a new lease for the increase? No. A rent increase continues the existing tenancy. Signing a new agreement reopens all of its other terms for negotiation.
