Debt Recovery Letter: Wording and Templates for Each Stage

A debt recovery letter is a written demand for payment of an overdue invoice. Written well, it gets an invoice paid without a court claim. Written badly, it gives the customer a reason to query the debt, and it can count against you later if the matter reaches court.

This guide explains how a debt recovery letter works for a business owed money by another business. It sets out the three stages, what each letter must contain, how long to give the customer, and three templates you can adapt. The templates are a starting point and not legal advice, so check the facts and the figures before you send anything.

What Is a Debt Recovery Letter?

A debt recovery letter asks the debtor to pay an amount by a stated date. It is not a court document and has no special legal force on its own. Its value is that it states the debt clearly, gives the customer a fair chance to pay or respond, and creates a record that you behaved reasonably.

Most businesses send them in stages. A reminder comes first, a firmer final demand second, and a letter before action last. Each stage raises the stakes while leaving room for the customer to pay or to explain. Our guide to debt recovery for small business covers the whole sequence.

Stage One: The Payment Reminder

Send the first letter or email within days of the due date. Most late payments are oversights, and a clear, friendly reminder settles many of them. Quote the invoice number, the amount, the due date and how to pay, and attach a copy of the invoice.

Subject: Overdue invoice [invoice number]

Dear [name],

Our invoice [invoice number] for £[amount], dated [invoice date], fell due on [due date]. Our records show that it is unpaid, and a copy is attached.

Please pay £[amount] by [date] to [account name, sort code and account number], quoting [reference]. If you have already paid, please tell us the date and method so we can trace the payment. If you have a query about the invoice, please let us know in writing now so that we can deal with it.

Kind regards,

Stage Two: The Final Demand

If the reminder is ignored, send a firmer letter that refers to the first one, repeats the figures and sets a new deadline. For a business-to-business debt, this is where you can add statutory interest and the fixed sum for each late invoice under the Late Payment of Commercial Debts (Interest) Act 1998, unless your contract has its own substantial remedy for late payment. Show the working for each invoice separately.

Subject: Final demand: invoice [invoice number]

Dear [name],

We wrote on [date of reminder] about invoice [invoice number] for £[amount], which fell due on [due date]. It remains unpaid.

The amount now due is the invoice, £[amount]; interest at [rate]% a year from [start date] to [date], £[amount], and continuing at £[daily amount] a day; and fixed compensation of £[40, 70 or 100] for the late invoice. The total is £[total].

Please pay this by [date, at least 7 days away]. If you dispute any part of the invoice, tell us which part and why, in writing, by the same date, and pay the undisputed part.

If we do not receive payment or a proper response, we will send a formal letter before action, and interest will continue to build.

Yours sincerely,

Stage Three: The Letter Before Action

The letter before action is the final warning before a court claim. It sets out the debt in detail, encloses the key documents, gives a deadline and says plainly that you will start proceedings if the debt is not paid. Courts expect this step and skipping it can affect who pays the costs even if you win.

Subject: Letter before action: [company name]: invoice(s) [numbers]

Dear [name or the directors],

This is a letter before action. We are writing about money owed by [debtor’s full registered name] to [your full registered name].

1. The debt. Under [contract or order, with date] we supplied [goods or services]. The following invoices are unpaid: [invoice numbers, dates, due dates and amounts]. The total is £[total]. Copies are enclosed with a statement of account.

2. Interest and compensation. We claim interest under the Late Payment of Commercial Debts (Interest) Act 1998 at [rate]% a year, which is £[amount] to [date] and £[daily amount] a day after that, and fixed compensation of £[amount] for each late invoice, £[total] in all.

3. What we require. Please pay £[total] by [date, at least 14 days from the date of this letter] to [bank details], quoting [reference].

4. If you do not pay. We intend to start a claim in the County Court without further notice, and to ask the court to order you to pay the debt, interest, court fees and our costs.

5. If you dispute the debt. Please explain why, and send any documents you rely on, by the same date. We are willing to discuss mediation or another way of resolving a genuine dispute.

Yours faithfully,

[Name & Position}

What Every Debt Recovery Letter Should Contain

• The correct legal names and addresses of both businesses, using the registered name for a company.

• The invoice numbers, dates, due dates and amounts, with copies attached.

• The basis of the debt: the contract or order and what was supplied.

• Interest and fixed sums worked out and shown for each invoice.

• A clear deadline stated as a date, not a number of days.

• How to pay, with bank details and a reference.

• What you will do if the debt is not paid.

• A way for the customer to respond or explain a dispute.

How Long Should You Give the Customer?

For a company, LLP or partnership, the Practice Direction on Pre-Action Conduct and Protocols expects a reasonable time to reply, and many creditors allow 14 days for a straightforward invoice. Where the debtor is an individual or sole trader, the Pre-Action Protocol for Debt Claims applies, with a letter of claim, an information sheet, a reply form and a financial statement form, and 30 days to respond. Check which rules apply before you choose a deadline.

Sending the Letter and Keeping Proof

Send it to the registered office or the last known address by first class or recorded post, and by email as well where your contract allows, or the customer has used that address for business. Keep a copy of the letter, the enclosures and the proof of sending together. If the matter reaches a court, you will need to show what you sent and when.

Common Mistakes in Debt Recovery Letters

• Vague amounts, or interest and fixed sums that are not itemised for each invoice.

• Using the wrong rules or giving a deadline that is too short.

• Claiming both contractual and statutory interest on the same debt.

• Threatening action, you do not intend to take.

• Sending a final demand about a debt that is genuinely disputed, without addressing the dispute.

• An aggressive tone that reads badly if a judge sees the letter later.

What Happens If the Letter Is Ignored?

If the deadline passes, you can consider a statutory demand for a debt that is clear, due and undisputed, or a county court claim. Both are worth weighing against the size of the debt and whether the customer can pay. Issuing a claim and enforcing a judgment are work for appropriately regulated litigation professionals, not for MAR Legal.

Final Thought

A good debt recovery letter is short, accurate and consistent with the ones before it. Keep the same figures and the same tone at every stage, set real deadlines, and keep copies of everything. Most invoices are paid at the first or second letter.
