Rent Arrears in the First 30 Days: A Written Follow-Up Before Any Legal Notice
In the first 30 days of late rent, verify the unpaid period, send a courtesy note then a dated chase, log the promise, write a payment-plan file — then stop.

Key takeaways
The practical file for how landlords handle rent arrears first 30 days is a schedule check, a same-week courtesy note, a dated written chase, a reply log, and a payment-plan document — then you stop. Confirm the period is actually unpaid before you write. A verbal next-week promise is weaker than no promise unless you record a date and amount.
Rent is late and the only record is a phone promise nobody wrote down. Build a same-month file: confirm the period is unpaid, send a same-week courtesy note, then a dated written chase, log the promised date, and write a payment-plan file if they cannot pay in full. You leave with a dated chase record the tenant can check, and you stop before any legal notice.
Two flats, one standing order fails on the 1st. You call, hear “I’ll sort it Friday”, and file nothing. Week three they say they never agreed a date. The written chase plus a one-page plan would have closed the gap. A legal notice would have been the wrong next file.

How do you confirm the period is actually unpaid?
Before any message, match the contractual amount, the due date, any credit from an earlier overpayment, and whether money landed a day either side. A weekend or bank lag can make a paid period look empty. A wrong first figure is a risk that undermines the whole chase.
Do open the rent schedule — one row per contractual period — and the bank on the same desk. If that file is still a monthly tick, start with the spreadsheet process. Do not message from memory or a WhatsApp ping that never named the period. In practice a standing order that fails on the 1st is a miss; a transfer that cleared on the 3rd after a bank holiday is not.
UK first-month guides start by verifying the miss against your own file. For example, if last month’s overpayment still sits as credit, the figure you quote may already be covered.

Typical mistake: write after the schedule
Messaging from a WhatsApp ping before you open the period row. A wrong first figure is harder to walk back than a one-hour delay.
What is a courtesy note versus a dated written chase?
A courtesy note is a short same-week message that assumes a bank delay or a failed standing order. A dated written chase is the later letter or email that states the amount, the original due date, how to pay, and a payment deadline. Both are records. Neither is a legal notice.
Do send the courtesy note the week of the miss. Do not sit in silence until week three, and do not open with a legal-sounding first text.
Process guides put a same-day or same-week courtesy email first, then around day 7 a dated letter with amount, due date, an invite to call, and a short written plan if circumstances changed. Keep both copies.
A common day-by-day ladder is day 1 a friendly reminder, day 3 a call or firmer message, and day 7 a formal letter. Always write. Note the date, time and content of any call. A late-rent reminder documents what is owed and that you asked. Put names, address, amount overdue, original due date, balance, deadline and how to pay.
Tone: professional and factual. State the amount, the due date, the days overdue. Set a deadline in each written chase. Do not harass, change locks, cut utilities, or discuss the tenant with neighbours.

Courtesy note versus dated written chase
| Courtesy note | Dated written chase | |
|---|---|---|
| When | Same week as the miss | Around day 7 if nothing landed |
| Tone | Assumes a bank delay or failed standing order | Factual; states a payment deadline |
| What to write | Amount, due date, has it gone out | Amount, original due date, how to pay, deadline |
| Keep | Copy in the email or text log | Dated copy with the period file |
| Not | A legal notice | A legal notice |
Should you write the same day after a call?
Write the same day: date and time, the method, what they said, the date and amount they promised, and whether it was kept. Send that summary back and invite a correction in a short window. A phone “I’ll pay Friday” with no file is the gap this step closes.
Do follow every call with writing the same day. Do not leave “I’ll pay Friday” as the only line in your head.
Where they prefer phone or text, send a written summary and invite corrections within about 7–14 days. If they say “next week”, write the specific date and amount. A verbal promise you cannot show is treated as weaker than no promise.

“Next week” is not a logged promise
Write the calendar date and the amount, send it back, and ask them to confirm. A verbal Friday with no file is weaker than no promise at all.
How do you write a payment plan as a file, not a phone memory?
A payment-plan file is a written record of the arrears balance, dated instalments, and the ongoing contractual rent that still falls due on its own date. A handshake is not enough. If they cannot pay in full, put dates and amounts on paper that both sides keep.
Do put dates and amounts on paper. Do not accept “when I can” as a plan, and do not bury ongoing rent inside the arrears figure.
UK landlord associations list the fields a payment-plan file needs: exact arrears at the agreement date; dated weekly or monthly instalments; ongoing rent on top of arrears repayments; what you will do if an instalment is missed.
Act the week of the miss. Start with a friendly email or text and write every contact. If they cannot pay in full, consider asking for the first instalment when the plan is agreed. Send a short rent statement so the running balance is visible.
First 30 days of late rent — the ops file
Check the schedule and the bank
Confirm amount, due date, any credit, and whether a transfer landed a day either side. If it is paid or only a bank lag, do not chase.
Send a same-week courtesy note
Email or a saved text that assumes error: amount, due date, has it gone out. Keep a copy. This is a reminder, not a legal notice.
Send a dated written chase
If nothing lands and there is no clear reply, write around day 7: amount, original due date, how to pay, a deadline. If you phone, write the same day.
Log the reply and any promised date
Date, time, method, what they said, the date and amount they promised, whether it was kept. A next week with no date is not a logged promise.
Write a payment-plan file if they cannot pay in full
Arrears balance, dated instalments, ongoing rent still due on its own date, what happens if an instalment is missed. Both sides keep a copy.
Record a partial on the same period
Amount received, remainder, running balance. Do not close the month. Do not invent a new period.
Stop before a legal notice
Day 30 ends this file: schedule check, courtesy note, dated chase, reply log, and either payment or a written plan.
Where does a partial sit on the schedule?
Log the partial on the same period row. Do not close the month or invent a new period.
Do post the bank line next to the same period row. If you still lack that row, start with the rent schedule: one row per period, due versus paid, partials, and a running balance. A partial without that row is how May swallows April.
When to stop before a legal notice?
Day 30 is the end of this article. You should have a schedule check, a courtesy note, a dated chase, a reply and promise log, and either payment or a written plan. Formal notices are a different file and a qualified adviser — not this guide.
Do stop at the ops file. Do not draft a legal notice from this page. Workflow: open the period row → check the bank → send the courtesy note → date the chase → log the promise → write the plan or record the partial → stop.
Success bar: verify the period is unpaid, send a same-week reminder, follow a call in writing, log the promised date, write a plan, record a partial on the same period, and stop at day 30.
If the promise still lives only in chat, open the IziRento workspace to keep the lease, rent period, reminders and written note together.
This guide ends at the ops file
Day 30 is a schedule check, a courtesy note, a dated chase, a reply log, and either payment or a written plan. Formal notices sit with a qualified adviser, not in this H1.
FAQ
When is a reminder not a legal notice?
A dated note of amount, due date and an ask to pay is a chase record, not a prescribed notice. Keep a copy with the period file.
What do I write after a phone call?
Write the date, what was said, and the promised date and amount, then invite corrections in a short window.
What if they send a partial?
Post it on the period row. Same-row remainder: https://izirento.com/en-gb/blog/rent-schedule-who-paid-period
What are the first steps when a tenant misses rent?
Check the schedule and the bank, then send a same-week courtesy note with amount and due date. If nothing lands, follow with a dated written chase around day 7.
What belongs in a rent arrears payment plan?
Write the arrears balance on the agreement date, dated instalments, ongoing rent still due on its own date, and what happens if an instalment is missed.
Should I wait until week three to write anything?
No. Send a factual courtesy note the week of the miss, then a dated chase if there is no payment and no clear reply.
