Chasing unpaid invoices is part of running a business - but before you rush to court, you need to follow the Pre-Action Protocol for Debt Claims when it applies. Doing this properly can speed up payment, reduce costs and, if court is unavoidable, put you in the strongest position.
In this guide, we’ll explain in plain English when the protocol applies, what to send, the timelines to follow, and the common pitfalls that trip up creditors. We’ll also share practical steps and documents that make debt recovery smoother from day one.
What Is The Pre-Action Protocol For Debt Claims?
The Pre-Action Protocol for Debt Claims is part of the Civil Procedure Rules (CPR) and sets out the steps a business creditor must take before starting court proceedings against an individual debtor. It’s designed to encourage early engagement, information sharing, and settlement where possible, and to make litigation a last resort.
In practice, the protocol requires you to send a compliant Letter of Claim with specified enclosures, allow set timeframes for a response, consider any request for documents or time to seek debt advice, and explore alternative dispute resolution (ADR). Courts can impose costs sanctions if you don’t comply.
Think of the protocol as a structured, fair way to chase payment: it forces both sides to set out the facts, share documents and consider solutions like payment plans before things escalate.
Does The Debt Protocol Apply To Your Business?
The debt protocol applies where:
- You are a business creditor (any size business or sole trader), and
- The debtor is an individual - including a sole trader - and
- You are claiming a sum of money due under a contract (for example, unpaid goods or services).
It does not apply to business-to-business debts where the debtor is a company or LLP. For those claims, you should still follow the general Practice Direction – Pre-Action Conduct (send a clear letter before action, give reasonable time to respond, exchange key documents, consider ADR), but you don’t need to use the debt protocol forms.
The protocol also doesn’t apply where another specific pre-action protocol takes priority (for example, mortgage arrears or construction). If you’re unsure, it’s wise to get tailored advice before sending anything formal.
As a practical first step, check your records are in order. Accurate invoices, a clear Terms of Trade and evidence of delivery or acceptance make all the difference. If you’re still at the invoicing stage, review the basics of UK invoice law and your chasing process to avoid unnecessary disputes later.
How To Comply: Step-By-Step Process
1) Prepare Your Evidence And Calculate The Balance
Start by pulling together the documents that prove the debt and how you calculated it:
- The contract or terms under which the debt arose (for example, a signed order or your standard terms).
- Invoices and credit notes.
- A statement of account with all payments and interest/charges shown.
- Any assignment notice if the debt has been assigned.
- Delivery notes, acceptance emails or other proof that the goods/services were supplied.
Be precise about interest and late fees. Only add what your contract or statute allows. If your terms specify late payment interest, cite the clause. If you rely on statutory interest under the Late Payment of Commercial Debts (Interest) Act, explain the rate and calculation.
2) Send A Compliant Letter Of Claim With Enclosures
The protocol requires you to send a Letter of Claim to the debtor’s last known address and allow at least 30 days for a response. This must include specific information and documents (we’ll cover the content in the next section). Sending a non-compliant letter can waste time and cost you credibility before a judge.
If you already use a Letter Before Action, you’ll need to adapt it to the debt protocol format when the debtor is an individual. If your claim is about non-payment under a contract, you might also send a formal breach of contract letter - but the protocol’s Letter of Claim is still required.
3) Give The Debtor 30 Days To Reply (And Pause If They Ask For Help)
Once the Letter of Claim is received, the debtor has 30 days to complete and return the Reply Form. If they request documents, you should provide them within 30 days and then allow a further 30 days from provision before issuing proceedings. If they say they’re seeking debt advice, you should allow reasonable extra time - typically a further 30 days - and avoid issuing during that period.
4) Engage In Meaningful Dialogue And Consider ADR
Use the reply to clarify any disputes, share documents and explore practical solutions. That could include:
- A short-term deferral while they seek advice.
- Payment by instalments based on their financial information.
- A lump-sum settlement at a discount (documented in a Deed of Settlement).
- Mediation, a without-prejudice meeting or written negotiation.
The court will look favourably on a creditor who genuinely tried to resolve matters without litigation.
5) Take Stock Before Issuing Proceedings
If you can’t agree a resolution, the protocol expects both parties to “take stock” before starting a claim - essentially, check whether litigation is proportionate and whether a final exchange of information could still avoid court. Keep a note of what you considered and why you proceeded; this can help on costs later.
What To Put In Your Letter Of Claim (With Timelines)
Your Letter of Claim must be clear, complete and accompanied by specific attachments. At minimum, it should cover:
Mandatory Content
- Creditor details: your business name, company number and contact details.
- Debtor details: the full name and last known address of the individual (and trading name if a sole trader).
- The agreement: a brief description of the contract, when it was made, and what was supplied.
- The amount due: principal, interest and any charges, with the calculation method and dates.
- Key documents: copies of the contract/terms, relevant invoices and a statement of account.
- How to pay: bank details or a link/phone number for payment.
- What happens next: that you’ll consider court action if not resolved, but you are open to ADR or repayment proposals.
Required Enclosures
You must enclose the protocol’s standard forms:
- Information Sheet (explaining the process).
- Reply Form (for the debtor to indicate whether they agree/disagree, request documents, or seek time).
- Standard Financial Statement template (so the debtor can propose affordable instalments).
The debtor then has 30 days from the date of the letter to respond, so make sure the date is clearly shown. If you post the letter, allow time for delivery and consider sending via recorded delivery. Keep proof of posting and copies of everything you send.
Timelines You Must Respect
- Minimum 30 days for the debtor to respond to the Letter of Claim.
- If documents are requested, provide them within 30 days and then wait a further 30 days before issuing.
- If the debtor says they’re seeking debt advice, allow reasonable extra time - generally at least 30 more days.
- Don’t issue proceedings while you’re considering an affordable repayment plan, or during a reasonable period for ADR.
Missing or ignoring these timeframes risks costs sanctions later, even if you “win” the case. Build them into your internal credit control calendar.
Settlement, ADR And What Happens If You Don’t Comply
Encouraging Early Resolution
The protocol strongly encourages early settlement. If the debtor sends a completed Reply Form with a realistic instalment offer backed by their financial statement, consider accepting or counter-proposing. Where you agree a plan, confirm it in writing and set review points.
If a negotiated deal needs finality (for example, part-payment in exchange for discontinuance), record the terms in a simple Deed of Settlement. For court-based settlements, parties sometimes use a Tomlin order to stay proceedings on agreed terms.
Alternative Routes: Assignment Or Third-Party Collection
Depending on your cash flow needs, you might instruct a collector under a services agreement or sell a debt outright. If you share the debtor’s personal data with a third party, ensure you have a lawful basis and a clear approach to sharing personal information under UK GDPR. Accurate records and fair communication are essential whichever path you choose.
The Risk Of Non-Compliance
Failing to follow the protocol can have real consequences:
- Cost penalties or interest disallowed, even if you succeed at trial.
- Proceedings stayed (paused) until you comply - adding delay and expense.
- Judicial criticism, which can affect case management and settlement leverage.
By contrast, demonstrating careful compliance - correct forms, genuine engagement, reasonable timelines - strengthens your position on costs and credibility.
Practical Tips To Avoid Common Mistakes
- Use the correct protocol: apply the debt protocol only if the debtor is an individual (including a sole trader). Otherwise, follow the general pre-action conduct guidance.
- Include all mandatory enclosures: missing the Reply Form or financial statement template is a classic error.
- Be precise about interest and charges: support them with your contract or statutory basis and show the maths.
- Respect the 30-day windows: issue too early and you risk a stay or costs consequences.
- Respond to document requests: send what’s reasonably asked for within 30 days and diarise the new 30-day wait.
- Record all communications: keep copies of letters, emails, call notes and any ADR correspondence.
Contracts And Processes That Make Debt Recovery Easier
The best way to make the debt protocol smooth is to prevent disputes from arising in the first place and to keep your evidence tidy. A few foundational steps go a long way:
- Put clear, robust Terms of Trade in place covering pricing, delivery, acceptance, interest on late payment and recovery costs.
- Send compliant invoices promptly and follow a structured chasing process backed by invoice law best practice.
- Where a dispute emerges, escalate with a well-structured breach of contract letter and then a protocol-compliant Letter of Claim.
- When you agree concessions or part-payment, record them in a concise Deed of Settlement.
If your internal template letters are outdated, consider refreshing them so they align with the protocol and your current terms. This avoids last-minute scrambling and inconsistent communications.
What If You Still Need To Issue Proceedings?
If settlement isn’t possible and you’ve complied with the protocol, you can issue a claim via the County Court Money Claims Centre (or online where appropriate). Attach the key documents you’ve already shared to keep things efficient. Ensure your particulars are consistent with the Letter of Claim and that you can explain the steps you took to resolve the matter pre-action.
Even after issuing, keep talking. Most debt claims settle before trial. When you do reach a deal, formalise it and consider whether to seek a consent order, especially if you need the court’s power to enforce payment terms.
Key Takeaways
- The Pre-Action Protocol for Debt Claims applies when a business is claiming a debt from an individual (including a sole trader). Business-to-business claims use the general pre-action conduct rules instead.
- A compliant Letter of Claim must include specific information and enclosures (Information Sheet, Reply Form and Financial Statement) and give the debtor at least 30 days to respond.
- Build the protocol’s timelines into your process: allow 30 days to reply, 30 days to provide requested documents, and extra time if the debtor is seeking debt advice.
- Courts can penalise non-compliance through costs, delays and interest decisions. Careful compliance strengthens your position even if the matter proceeds.
- Strong foundations - clear Terms of Trade, accurate records, structured chasing and, where needed, a Deed of Settlement - make debt recovery faster and less stressful.
- If cash flow is critical, consider third-party options and the legalities if you plan to sell a debt, and handle any data sharing in line with UK GDPR.
- Templates and processes matter. Align your Letter Before Action with the protocol, and keep your approach consistent from invoice to pre-action correspondence.
