I Have No Knowledge of this Debt Template Letter
A letter drops through the door, or an email arrives, or the phone rings at 8am from a number you don’t recognise. Someone is chasing your company for a debt you have never heard of. You don’t know the creditor.
You don’t recognise the account number. You don’t owe this money. Or at least, you have no reason to believe you do.
This is not as unusual as it sounds. Creditors chase the wrong entity, use outdated contact details, mix up company names after a business transfer, or pursue debts that were settled by a previous director before you joined.
Debt collectors working on commission sometimes contact businesses at speed and without thorough checks. Whatever the reason you are receiving this demand, you are entitled to ask the creditor to prove it.
This page gives you a template letter to do exactly that. But before you copy and adapt it, read the framing sections below. This letter is not a magic eraser.
It shifts the burden of proof to the creditor, and many creditors can meet that burden.
If you genuinely owe the debt, this letter will not make it go away. It will only delay the creditor while they gather their paperwork. Use it correctly, and it is a legitimate tool.
Use it carelessly, and you may acknowledge a debt you were trying to dispute, or harden a creditor’s position.
When to Send the “I Have No Knowledge of This Debt” Letter
Quick Answer: When This Letter Applies
Send this letter when your company has received a demand for payment and you have no record of the underlying transaction, contract, or credit agreement.
It is appropriate when you have checked your accounts, searched your records, and cannot identify what the debt relates to. It is a formal request for the creditor to provide proof that the debt exists and that your company is liable for it.
Who Should Use This Letter
This letter is written for company directors receiving demands addressed to the company. It asks the creditor to confirm the basis of the debt in writing. You can send it in your own name as director, or adapt it for joint directors.
If you are a sole trader rather than a limited company director, the same principle applies, but the personal exposure is different. We recommend taking advice on your full position before replying to any personal debt demands.
The letter is also appropriate when you have recently taken over a company (through a share purchase or otherwise) and a creditor is chasing a debt from the previous directors’ time that you cannot verify.
In that situation, you need a written record from the outset that you have put the creditor on notice.
When This Letter Will NOT Help
Do not use this letter as a delay tactic if you know, or strongly suspect, the debt is legitimate. Creditors are entitled to pursue debts owed to them.
If your company traded with this creditor and simply has not paid, a “no knowledge” letter will harden their position and may accelerate enforcement action.
Sending a dishonest dispute letter could also affect how a court views your conduct later, particularly if insolvency proceedings follow.
This letter is also not a substitute for the HMRC dispute process if the demand comes from HMRC. HMRC has its own statutory processes for challenging assessments and penalties. A general creditor dispute letter will not stop HMRC enforcement.
One more distinction worth making clearly: if the debt might be real but very old, you are in different legal territory. Under the Limitation Act 1980 s.5, a creditor generally has six years to bring a claim for a simple contract debt.
While the six years are still running, a signed written acknowledgement of the debt, or a payment, restarts the clock. Once the debt is statute-barred, a later acknowledgement cannot revive it. Before writing anything, check when the alleged debt arose.
What to Have Ready Before You Send It
Before you adapt and send the letter below, do four things. First, search your accounting records and bank statements for any transaction that might correspond to the creditor’s claim: supplier name, invoice reference, account number, or amount.
Second, check Companies House to confirm the creditor is communicating with the right legal entity. Third, note the date the demand arrived. Fourth, keep a copy of the demand itself. You will need all of this if the dispute escalates.
If your company has had more than one director, check with your co-directors or predecessor directors before sending. A debt you have no knowledge of may be one another director authorised without informing you.
What the Creditor Must Do When You Send This Debt Dispute Letter
The Burden of Proof Shifts to the Creditor
If the creditor is an FCA-regulated firm and you dispute the debt on grounds that may be valid, it must suspend recovery while it looks into the dispute. A trade creditor outside FCA rules is not bound by that, but any creditor that takes you to court has to prove the debt. This is the core purpose of the letter: it puts the obligation on them to show their working.
If they cannot produce a signed agreement, a statement of account, or documentary evidence of the transaction, they should not be pursuing the claim.
This matters in practice. Debt collectors operating at scale often hold incomplete records. Secondary debt purchasers (firms that have bought bad debt portfolios from original creditors) sometimes chase with limited documentation.
Sending a clear written dispute forces them to locate the original paperwork, which they may not have.
Statutory Basis: CCA 1974 and FCA CONC Rules
For consumer credit debts (credit cards, loans, hire purchase), sections 77, 78, and 79 of the Consumer Credit Act 1974 give you the right to request a copy of the original credit agreement. The creditor has 12 working days to comply.
While they are in default of that request, the debt is unenforceable through the courts. Note that this right applies to regulated consumer credit agreements.
Business-to-business credit is governed differently, but the general principle holds: a creditor must be able to prove what is owed.
Under FCA CONC 7 (Arrears, Default and Recovery), firms engaged in debt collection must treat customers fairly. For a regulated firm, carrying on recovery of a debt disputed on valid or possibly valid grounds, before it has looked into the dispute, breaches FCA rules.
If you are being chased aggressively after sending this letter without the creditor addressing the dispute, that is a Financial Ombudsman Service complaint in the making.
What “Unenforceable” Means in This Context
Unenforceable does not mean the debt disappears. It means the creditor cannot enforce it through the courts while they are in default of a statutory information request. For regulated firms, the same applies while a live dispute has not been addressed.
The debt may still exist on paper. If the creditor resolves the default and provides the required documents, enforcement becomes possible again. Do not confuse “unenforceable” with “cancelled”.
The Template Letter: Copy and Adapt for Your “No Knowledge of This Debt” Dispute
Adapt the letter below. Replace the bracketed fields with your details. Send by recorded post and keep a copy. Do not sign with your personal signature if you can use a company stamp instead. More on that below.
[Your company name]
[Your registered address]
[Date]
[Creditor or debt collection firm name]
[Their address]
Dear Sir/Madam
Re: Alleged Debt: [Reference number if shown on demand] / [Your company name] / FORMAL DISPUTE
I am writing to you as a director of [name of your company] in response to your demand for payment dated [date of their letter].
This letter is to inform you that we do not recognise this debt, have no record of the transaction or agreement you are relying upon, and have no knowledge of its existence.
Your demand appears to have been sent to [name of your company] in error. We require you to stop all collection activity while this dispute is open.
If you believe this debt is owed by our company, you must provide us with the following in writing within a reasonable time:
- The original credit agreement or contract giving rise to the alleged debt, including the date it was entered into and the name of the individual who authorised it on behalf of our company.
- A full and itemised statement of account showing how the alleged amount has been calculated.
- Evidence that your company has the right to collect this debt, including details of any assignment from the original creditor.
If you have provided any details of this alleged debt to a credit reference agency, you must notify us of this immediately and must inform the agency that the debt is disputed.
Unless you can provide evidence that the debt is legitimately owed, this information must be corrected or removed.
We await your written response. Until we receive satisfactory evidence of liability, we will treat this matter as closed and will not make any payment.
Yours faithfully,
[Your full name]
Director, [company name]
What to Expect After You Send the “No Knowledge of This Debt” Letter
12 Working Days for a Statement of Account or s.77 Response
If the debt is a regulated consumer credit agreement, the creditor has 12 working days to provide the information requested under sections 77 or 78 of the Consumer Credit Act 1974. Put that date in your calendar the day you send the letter.
If they fail to provide the documents by that date, the debt is legally unenforceable until they do. Keep the recorded delivery receipt.
For non-regulated business debts, there is no fixed statutory clock. The creditor should respond within a reasonable time.
If you hear nothing for 28 days, you can follow up in writing, referring to your original letter and their obligation to provide evidence before pursuing the claim.
When to Escalate to the Financial Ombudsman
If the creditor is a regulated firm (a bank, a credit card provider, a regulated finance company) and they continue collection activity after receiving your formal dispute without addressing the substance of it, you can complain to the Financial Ombudsman Service.
The Ombudsman cannot order a firm to stop collecting while it investigates. FCA rules do require a regulated firm to suspend recovery while it looks into a dispute that may be valid.
You need to have complained to the firm directly first and received either a final response or waited eight weeks.
For unregulated creditors (trade suppliers, commercial lenders outside FCA scope), FOS does not apply.
Your options there are a formal legal dispute or, if the amount is significant, a challenge to any statutory demand before it leads to a winding-up petition. We recommend speaking to an adviser before that situation develops.
Common Creditor Tactics to Watch For
Some creditors and debt collection firms respond to dispute letters by calling rather than writing. Do not discuss the debt on the phone. Any conversation on a recorded line could be used to suggest you acknowledged the debt.
Keep everything in writing. If they call, tell them your position is set out in your letter and ask them to correspond in writing.
Others may continue sending automated chase letters while your dispute is being processed. That is not necessarily bad faith, large operations sometimes run chase cycles and dispute resolution on separate tracks.
What matters is whether, when a human actually reviews your file, they respond to the substance of your dispute. If the chase continues after a human-reviewed response and without evidence, that is the trigger for escalation.
Mistakes to Avoid With the “No Knowledge of This Debt” Letter
Do Not Sign the Letter With Your Personal Signature
Use a company stamp or typed signature block where possible. The letter is being sent on behalf of the company, not you personally.
A dispute letter is not the same as a personal guarantee, but you want the paper trail to clearly show the dispute relates to company liability, not your personal assets.
If the debt later proves to be one linked to a personal guarantee you signed, that is a different conversation entirely.
Do Not Acknowledge the Debt in Any Phone Call
Say nothing on the phone that could be interpreted as acknowledging the debt. Phrases like “I’m not sure we owe this” or “I’ll need to look into it” can be read as partial acknowledgement.
A spoken acknowledgement does not restart the six-year limitation period under the Limitation Act 1980. Only a signed written acknowledgement, or a payment, does that, and only while the period is still running. Keep calls short and keep everything in writing.
The only thing to say on the phone is: “Our position is set out in our letter. Please put everything in writing.”
Do Not Send the Letter Without Verifying the Creditor’s Address
Sending a dispute letter to an incorrect address wastes time and may fail to stop the clock on a statutory demand. Verify the creditor’s registered address via Companies House before sending recorded post.
If the demand came from a debt collection firm acting as agent, address your letter to the original creditor and copy the collection firm. Make sure both parties have your dispute on record.
Your Next Step If the Creditor Cannot Prove This Debt
If the creditor responds to your letter but cannot produce the original agreement or a satisfactory statement of account, the debt is unproven. You do not have to pay while the creditor fails to show the debt is owed. If the debt is genuine, though, it is still payable and the creditor can prove it in court.
Confirm your position in writing: acknowledge their response, note that the evidence provided is insufficient to establish liability, and state that you are treating the matter as closed.
If they continue chasing without evidence, your options are a formal complaint (for regulated creditors), a legal challenge to any statutory demand, or, if the matter escalates to litigation, a defence that the debt has not been evidenced.
None of those outcomes is guaranteed to work in your favour unless you have kept a clear paper trail from the outset.
Here is the harder truth: if the creditor can produce the original contract, signed by a director of your company, then the dispute shifts. You may owe the debt. The letter will not help you at that point.
What it will have done is buy you time to verify the position and take proper advice on your options, whether that is negotiating the debt, challenging the amount, or understanding what happens if your company cannot pay.
If your company is under creditor pressure more broadly, not just from one disputed debt but from several creditors, the right starting point is understanding the full picture.
We work with directors across the UK who are facing exactly this kind of accumulated pressure. Talk to our team about your options before the situation narrows further.
Frequently Asked Questions About the “I Have No Knowledge of This Debt” Letter
Does sending this letter mean I am admitting I might owe the debt?
No. The letter explicitly states that you do not recognise the debt and have no knowledge of it. Asking a creditor to prove a debt is a normal step in any dispute and does not constitute an admission of liability.
The opposite is true: if you do nothing, that silence can sometimes be used against you in later proceedings. A clear written dispute on record is a stronger position than no response at all.
What if the creditor sends a statutory demand after I send the letter?
A statutory demand served on a company is serious. If the company does not pay, or reach terms the creditor accepts, within 21 days, the creditor can rely on the unpaid demand to show the company cannot pay its debts and present a winding-up petition. A company cannot apply to have a statutory demand set aside. That procedure is only for individuals.
If you have already disputed the debt in writing and the creditor serves a statutory demand anyway, that record helps show the debt is disputed on substantial grounds. That is the basis for asking the court to stop a winding-up petition. Do not wait for the 21 days to run out. Talk to us straight away.
The debt is very old. Does that change what I should do?
It might. Under the Limitation Act 1980 s.5, a creditor generally cannot bring a court claim for a simple contract debt after six years from when it became due. Or six years from the last written acknowledgement or payment.
If the debt is close to or past that limitation period, be careful about acknowledging it in any form. Your dispute letter should not reference the debt as one you once had dealings with. State simply that you have no knowledge of it. If you are unsure about the limitation position, take advice before writing anything.
Can a creditor register this debt against my company’s credit file if I have disputed it?
Under FCA CONC 7, regulated creditors must not report a debt to a credit reference agency in a misleading way. A disputed debt should be recorded as disputed.
If your company’s credit file shows a default on a debt you have formally disputed and have no knowledge of, complain to the creditor first. If it is an FCA-regulated firm and your company is a micro-enterprise or small business, you can then take the complaint to the Financial Ombudsman Service. Keep evidence of your dispute letter and any response when you make that complaint.
I recently bought a company and the debt is from the previous directors. What do I do?
This depends on whether you bought the shares in the company or just its assets. If you bought the shares, the company is still liable for its existing debts, including those from before you took over. In that case, the company may owe the debt, even if you personally knew nothing about it.
If you bought the assets of the business rather than the company itself, the old company’s debts should not follow you. Take legal advice on what you actually purchased before sending any letter, and check your acquisition documents.
What if the creditor ignores my letter and sends bailiffs?
In England and Wales, most creditors need a court judgment before bailiffs (enforcement agents) can act against a company. HMRC, and a commercial landlord owed rent, can use bailiffs without going to court first. If you have had no county court claim form and no judgment, ask anyone who turns up who instructed them and on what authority, and ask to see it.
An ordinary trade creditor cannot take enforcement action without going through the courts. If you are facing enforcement action and have an open dispute letter on file, contact an insolvency adviser urgently, the timelines at that point are short.
