Free Chase Letter Pack: Polite and Firm Reminders

Before a formal letter before action, we suggest sending two reminders: a polite first reminder on the day after the invoice's due date, and a firmer second reminder around 7 days overdue. Both templates are below, ready to copy. If neither works and the invoice is still unpaid around 30 days overdue, we suggest moving to our letter before action template, the next and final step before court.

This chase letter pack for an unpaid UK invoice has two stages before a formal letter before action: a polite first reminder sent the day after the due date, and a firmer second reminder sent around 7 days overdue that references the first reminder and gives a short deadline. Neither stage is a legal threat; that is kept for the letter before action, which we suggest at around 30 days overdue, which states a firm deadline and the intention to issue court proceedings.

This page covers:

UK payment reminder templates for unpaid invoices: a polite first reminder and a firmer second reminder, escalation timing before a letter before action, and handling invoice disputes.

Not covered here:

the formal letter before action itself and the Pre-Action Protocol for Debt Claims (see /tools/letter-before-action-template/), the original invoice template (see /tools/invoice-template/), and the wider unpaid invoices escalation ladder (see /unpaid-invoices/)

1. Polite first reminder (day after due date)

Send this as soon as an invoice becomes overdue, before assuming anything is wrong. Most late payments are oversight, not refusal.

2. Firm second reminder (around 7 days overdue)

Send this if the first reminder gets no payment or response. It references the earlier reminder, sets a short deadline, and flags formal next steps without yet being one.

SECOND PAYMENT REMINDER

[Your company name]
[Your address]
[Email]  [Phone]

[Date]

To: [Debtor name / company name]

Dear [name],

RE: Overdue invoice [invoice number], amount due GBP [0.00]

Our records show invoice [number], dated [invoice date] for
GBP [0.00], is now [7] days overdue. We sent a reminder on
[date of first reminder] and have not yet received payment
or a response.

Please arrange payment within the next [7] days, by
[deadline date].

Please pay to: [Bank name]  Sort code: [00-00-00]
Account: [00000000]  Reference: [invoice number]

If there is a reason payment has not been made, please
contact us before the deadline so we can discuss it. If we
do not hear from you or receive payment, we will need to
consider formal next steps, including a letter before
action.

We would rather resolve this directly and look forward to
hearing from you.

Kind regards,

When to stop reminding and escalate

If the firm reminder's deadline passes with no payment, no response, and no genuine dispute, the next step is a formal letter before action, which we suggest once the invoice reaches around 30 days overdue. Sending a third or fourth soft reminder past that point usually just signals your deadlines are not real. Save the explicit threat of court proceedings and statutory interest for the letter before action itself.

Waiting on the cash instead of the chase

Chasing recovers one invoice, slowly, on the debtor's timetable. Invoice finance can release part of the cash tied up in your unpaid invoices early, with the rest (less fees) paid when the customer pays. How much and how fast depends on the provider. With factoring, the provider also chases your customers for you; with invoice discounting, you still do the chasing yourself.

Chase Letter Pack FAQ

What is the difference between a payment reminder and a letter before action?

A payment reminder is an informal chase, asking politely or firmly for payment with no legal threat attached. A letter before action (LBA) is a formal notice that you intend to start court proceedings if payment is not received by a stated deadline. Courts and the Pre-Action Protocol for Debt Claims expect a creditor to have given a genuine chance to pay before an LBA, which is why sending reminders first matters, not just for tone but for the paper trail.

How many reminders should I send before a letter before action?

We suggest two for a straightforward B2B invoice: a polite reminder on the day after the due date, and a firmer second reminder around 7 days overdue. If there is still no payment or reply by around 30 days overdue, we suggest moving to a formal letter before action. Sending more than two soft reminders without escalating usually just teaches the debtor that your deadlines are not real.

Should I mention court action in the second reminder?

A brief, factual mention that you will need to consider formal next steps if payment is not received is reasonable and keeps the letter honest about where things are heading. Save the specific threat of court proceedings and a firm deadline for the letter before action itself, since overusing the threat in an early reminder weakens it later.

What if the customer disputes the invoice instead of paying?

Deal with the dispute on its own terms before escalating: ask what specifically is wrong with the invoice, correct it with a credit note if they are right, or explain clearly why it is correct if they are not. Escalating to a letter before action over a genuine, unresolved dispute usually backfires and can complicate a later court claim.
