How many payment reminders should I send before taking action?

Three to four reminders is standard: a friendly reminder shortly after the due date, a firm follow-up at 7-14 days, and a final notice at 21-30 days. After the final notice, you should move to formal recovery (Letter Before Action). More than four reminders teaches clients that your deadlines are not real.

When should I send my first payment reminder?

Send a brief reminder 1-3 days after the invoice due date. This catches genuine oversights quickly. Some freelancers also send a pre-due-date reminder 3-5 days before the due date, which can be even more effective at preventing late payment.

Should I charge late payment interest on overdue invoices?

Under the Late Payment of Commercial Debts (Interest) Act 1998, UK businesses have the right to charge statutory interest of 8% plus the Bank of England base rate on overdue invoices between businesses. You can also claim fixed compensation: £40 for debts up to £999.99, £70 for debts of £1,000-£9,999.99, and £100 for debts of £10,000 or more.

Invoice Payment Reminder Schedule: When to Chase, What to Say, When to Escalate

Published: 17 March 2026 · For UK freelancers and sole traders

Most freelancers either chase too softly (endless "just checking in" emails that get ignored) or wait too long (hoping the money will magically appear). Neither works.

What works is a structured escalation sequence — each step slightly firmer than the last, with clear deadlines and consequences. Here's the exact schedule.

The complete reminder schedule

When	Action	Tone
3-5 days before due	Pre-due date nudge (optional)	Casual
1-3 days overdue	Friendly reminder	Warm
7-10 days overdue	Firm follow-up	Professional
14-21 days overdue	Final notice	Serious
28-30 days overdue	Letter Before Action	Formal/legal
44+ days overdue	Small claims or debt recovery	Legal

Each step in detail

FRIENDLY

Day 0-3: The friendly reminder

Goal: Catch genuine oversights. Most late payments are admin errors, not intentional.

Tone: Light, no pressure. Assume they forgot.

Subject: Invoice #[NUMBER] — quick reminder Hi [NAME], Just a quick note — invoice #[NUMBER] for £[AMOUNT] was due on [DATE]. Could you let me know when I can expect payment? Happy to resend the invoice if needed. Thanks, [YOUR NAME]

Response rate: About 60% of overdue invoices get paid after this single email.

PROFESSIONAL

Day 7-10: The firm follow-up

Goal: Make it clear this isn't going away. Reference the first reminder.

Tone: Polite but direct. No "just checking in."

Subject: Invoice #[NUMBER] — now [X] days overdue Hi [NAME], Following up on my email from [DATE] — invoice #[NUMBER] for £[AMOUNT] is now [X] days past the agreed payment date of [DUE DATE]. Could you confirm when this will be processed? If there's a problem with the invoice itself, I'm happy to resolve it quickly. I'd appreciate a response by [DATE — give 3 days]. Best, [YOUR NAME]

SERIOUS

Day 14-21: The final notice

Goal: Last chance before escalation. Mention consequences.

Tone: Direct and factual. No anger, just clarity.

Subject: Invoice #[NUMBER] — final reminder before escalation Dear [NAME], This is my third contact regarding invoice #[NUMBER] for £[AMOUNT], originally due on [DUE DATE]. Despite previous reminders on [DATES], this invoice remains unpaid. Please arrange payment within 7 days (by [SPECIFIC DATE]). I should also note that under the Late Payment of Commercial Debts (Interest) Act 1998, I am entitled to charge statutory interest of [X]% per annum plus fixed compensation of £[40/70/100] on this overdue amount. If I don't receive payment or a response by [DATE], I will need to consider formal recovery options. Regards, [YOUR NAME]

FORMAL

Day 28-30: Letter Before Action (LBA)

Goal: Formal legal pre-action step. Required before court action.

Tone: Formal. This is a legal document.

An LBA gives the debtor 14 days to pay before you file a claim. For amounts under £10,000, this goes to the small claims court. You don't need a solicitor.

See our Letter Before Action template for the full wording.

Timing tips that actually work

Send reminders on Tuesday-Thursday mornings. Monday inboxes are full. Friday emails get buried over the weekend.
Send at 9-10am in the recipient's timezone. Catch them when they're processing emails.
Always reply to the previous email thread. This shows a paper trail and makes it harder to claim they "didn't see" earlier messages.
CC accounts/finance if available. If your contact isn't the person who processes payments, ask who is and include them.
Keep records of every contact. Dates, method, what was said. You'll need this if you go to court.

What NOT to do

Don't send more than 3-4 reminders. After that, escalate. Repeated soft reminders teach clients that your deadlines are meaningless.
Don't apologise for chasing. "Sorry to bother you" undermines your position. You did work. You're owed money. That's not a bother.
Don't make empty threats. If you say you'll take legal action, be prepared to follow through.
Don't get emotional. Angry emails feel good to write and terrible to send. Keep it factual.
Don't stop working on active projects. Unless your contract allows it, stopping work can put you in breach even if the client hasn't paid previous invoices.

💡 Prevention is better than chasing. The best way to avoid late payments: clear payment terms in your contract, deposits upfront (30-50% is standard), and milestone payments for larger projects. See our deposit policy guide.

Your statutory rights on late payment

Under the Late Payment of Commercial Debts (Interest) Act 1998, you can charge:

Statutory interest: 8% + Bank of England base rate (currently 4.5%) = 12.5% per annum on the overdue amount
Fixed compensation: £40 (debts under £1,000), £70 (£1,000-£9,999.99), or £100 (£10,000+)
