UK invoice-chase pack

Three short emails for an overdue business-to-business invoice: a polite nudge, a Late Payment Act notice, and a final notice. Free to copy. No paywall. No signup.

Not legal advice. The Late Payment of Commercial Debts (Interest) Act 1998 is for qualifying commercial debts, not consumer invoices. A contract with a different substantial remedy can change what you can claim. Read GOV.UK: charging interest on a commercial debt and swap the placeholders before you send.
Late-payment calculator (free, already live): https://brewpage.app/public/oPragoaCnk — estimate statutory interest and the fixed compensation sum. An estimate, not advice.
Email 1 · polite reminder

Before you mention interest

Subject: Invoice [INVOICE NO] — a quick reminder

Hi [CLIENT NAME],

Invoice [INVOICE NO] for £[AMOUNT], due on [DUE DATE], still shows as unpaid on my side.

Could you confirm it is in this payment run, or tell me if anything on the invoice needs correcting?

Thank you,
[YOUR TRADING NAME]
Email 2 · Act notice

Statutory interest, still short

Subject: Invoice [INVOICE NO] — overdue under the Late Payment Act

Hi [CLIENT NAME],

Invoice [INVOICE NO] for £[AMOUNT] was due on [DUE DATE] and is still unpaid.

This was a business-to-business supply. Under the Late Payment of Commercial Debts (Interest) Act 1998 I am entitled to statutory interest at 8 percentage points above the Bank of England reference rate, from the day after the due date, plus a fixed sum for debt-recovery costs (£40 if the debt is under £1,000, £70 if it is £1,000 to £9,999.99, or £100 if it is £10,000 or more).

Please pay the invoice. If it is still open when I write again, I will add that interest and fixed sum.

Email 3 · final notice

Last note before you escalate

Subject: Invoice [INVOICE NO] — final notice

Hi [CLIENT NAME],

Final notice: invoice [INVOICE NO] for £[AMOUNT], due [DUE DATE], remains unpaid.

Please pay within 7 days. I am claiming the invoice plus statutory interest and the fixed recovery sum under the Late Payment of Commercial Debts (Interest) Act 1998, unless our contract already sets a different substantial remedy.

If I do not receive payment I will treat this as a formal recovery matter. I would rather close it by payment.
