How to Write a Legally Compliant Letter Before Action in England and Wales (2025)

Staring at an unpaid invoice is one of the most frustrating parts of running a business. You've done the work, sent polite reminders, but the payment deadline has long passed, and your cash flow is suffering. What’s the next step you can take without spending a fortune on solicitors?

This guide walks you through the most powerful tool at your disposal before court action: the Letter Before Action (LBA). We'll show you how to write a legally compliant letter before action for unpaid invoice that gets results, backed by insights from Garfield AI, the world's first AI law firm regulated by the SRA.

You’ll learn how to create an LBA that gets you paid, protects you from costly legal mistakes, and helps you avoid unnecessary court proceedings.

What is a Letter Before Action (and Why is it a Legal Minefield)?

A Letter Before Action, sometimes called a Letter of Claim, is a formal, final warning sent to a debtor. It clearly states your intention to start court proceedings if they don't pay the outstanding amount by a specific deadline.

But it’s much more than just a strongly worded letter. It's a mandatory legal step required by England and Wales' Civil Procedure Rules (CPR) and the associated debt Pre-Action Protocol.

Getting this letter wrong can have serious consequences. A judge can penalise you for pre-action protocol non compliance, such as making you pay the other side's legal costs, even if you ultimately win your case. This is why using an SRA-regulated tool is a game-changer for small and medium-sized enterprises (SMEs), ensuring you follow the rules perfectly every time.

England and Wales' Pre-Action Protocol: The Rules You Can't Ignore

Pre-Action Protocols are sets of rules that courts in England and Wales expect parties to follow before a claim is issued. Their main goal is to encourage communication and early settlement, helping both sides avoid the time and expense of going to court. There are many different Pre-Action Protocols and there is one specifically for debt claims.

According to the official Pre-Action Protocol for Debt Claims from the Ministry of Justice, the process is designed to ensure both parties have all the information they need to understand the dispute and try to resolve it.

The Letter Before Action is the formal start of this process.

What Happens if Your Letter Isn't Compliant?

Failing to send a compliant LBA isn't just a minor administrative slip-up; it can directly harm your legal position.

Here are the potential risks of non-compliance:

• Proceedings Paused: A court could put your claim on hold until you follow the correct protocol, causing significant delays.
• Cost Penalties: You might not be allowed to recover fixed costs and you could be ordered to pay some or all of the debtor’s legal costs, even if they owe you the money. This is less likely to be a risk in a small claim for under £10k and is more likely to be a signfiicant risk in larger claims.
• Interest Denied: The court might refuse to award you interest on the debt for the period you failed to comply with the rules.

This is the core problem that both expensive solicitors and compliant AI tools are designed to solve. Sending a non-compliant letter can turn a clear win into a costly and frustrating ordeal.

The Anatomy of a Compliant LBA: Your Step-by-Step Checklist

To be effective and legally sound, your Letter Before Action must contain specific information. Think of it less as a letter and more as a formal legal document. Using a generic letter before action template can be risky, and is inadvisable, but following this checklist can help to ensure you include all the essential elements.

Step 1: Core Information

This is the foundational data that identifies the parties involved. Get these details right.

• Your Details (Claimant): Include your full name (or registered business name) and address.
• Debtor's Details (Defendant): Include their full name and current address. For a limited company, considering using their registered office address as well as their trading address.
• Date: The date you are sending the letter.
• Clear Heading: The letter could be clearly titled "Letter Before Action" or "Letter of Claim" to avoid any ambiguity.

Step 2: The Substance of Your Claim

Here, you need to clearly and concisely explain the money you are owed. Don't write an essay; keep it succinct and stick to the facts.

• Summarise the Facts: State the amount of the debt, and whether charges are continuing (and if they are, say what the figures are).
• Interest calculation: Show what interest has accrued so far and say how much interest will accrue daily hereafter. This will depend on whether the contract has a clause giving a right to interest, or whether the Late Payment of Commercial Debts (Interest) Act 1998 applies, or in lieu of those, the County Courts Act 1984. If you are able and wish to claim compensation under the Late Payment Act you should state this too and say how much you are claiming.
• Total Amount Due: Provide a final, total figure that includes the original debt, interest, and any compensation.
• Reference Key Documents: Mention any relevant invoices, including giving their numbers and their due dates. If the contract was in writing, give its date, who were parties to it and say a copy of it can be requested. If the contract was oral, you need to say who made it, what was agreed (including where possible what words were used) and when and where it was agreed.

Step 3: Additional details

Other points you should explain:

• If the debt has been assigned: You will need to give details of the original debt and creditor, when it was assigned and to whom.
• If the debtor has offered or is paying regular instalments: If these are not acceptable, you need to explain why not.

Step 4: The Deadline and Next Steps

This is the "action" part of the letter. You must be crystal clear about what you expect and what will happen if your expectations are not met.

• How to Pay: Provide clear instructions on how the debtor can make payment, such as your bank details for a transfer.
• Set a Reasonable Deadline: This is a critical legal requirement. For debts owed by individuals or sole traders, the Pre-Action Protocol requires you to give them 30 days to respond. This is usually considered a reasonable deadline for business to business debts as well.
• State Your Intention: End the letter with an unambiguous statement. For example: "If we do not receive a satisfactory response or full payment by [Date], we will commence court proceedings to recover the debt without further notice."

Can I Write a Letter Before Action Myself? DIY vs. Solicitor vs. AI

When you decide it’s time to send an LBA, you’re faced with a choice. Each option has its own balance of cost, risk, and time commitment. So, can I write a letter before action myself? Let's break it down.

Option 1: The DIY Route (Using a Template)

This involves finding a template online and filling in the blanks yourself.

• Pros: It’s free, though this is its only real advantage.
• Cons: The risks are high. Free templates are often generic and could miss crucial details specific to your case. An error in wording or a failure to include the right information can render your letter non-compliant, weakening your legal position before you even start. Also, all of this will take you time.
• Best for: Extremely simple, undisputed debts below a few hundred pounds, where you feel very confident you understand all the legal requirements. For most businesses, the risk outweighs the saving.

Option 2: The Traditional Solicitor

This is the long-established route of hiring a law firm to draft and send the letter on your behalf.

• Pros: You get a legally compliant and authoritative letter. The solicitor's letterhead alone can often be enough to prompt immediate payment from a hesitant debtor.
• Cons: The cost is a major barrier. How much does a solicitor charge for a letter before action? Fees can easily range from £150 to over £500 + VAT for a single letter, with no guarantee of success. The process can also be slow, involving consultations and back-and-forth communication.
• Best for: Larger debts (e.g., over £25,000) or highly complex disputes where there are significant factual disagreements or points of law to be argued.

This modern approach uses technology to deliver a compliant legal document in seconds without the traditional overheads.

What Happens After You Send the LBA?

Once the letter is sent, one of three things will typically happen. Being prepared for each scenario will help you stay in control of the process.

Scenario 1: They Pay in Full

This is the best-case scenario and the primary goal of the LBA. The debtor receives the formal letter, understands you are serious, and settles the full amount.

Once the payment clears, send them a brief, formal receipt confirming the payment has been received and that the matter is now considered closed.

Scenario 2: They Respond but Don't Pay

The debtor might reply to dispute the debt, ask for more information or documents, propose a payment plan, or ask for a discount.

The Pre-Action Protocol requires you to engage with any reasonable request. Garfield will help you respond professionally and constructively. Garfield will help you keep a written record of all communication, as a Judge will expect to see that you've made a genuine effort to settle the dispute before resorting to court action.

Scenario 3: They Ignore the Letter

If the deadline passes with no payment and no communication, you have a clear path forward.

Because you have sent a fully compliant Letter Before Action, you have fulfilled your pre-action obligations. You are now in a strong legal position to proceed with making a court claim for money. This is the point where you would begin the process of issuing a claim in the Small Claims Court. Garfield will help you draft that claim quickly, easily and without hassle.

How to Respond if You Receive a Letter Before Action

To provide a complete picture, it's useful to know how to respond to a letter before action if you ever find yourself on the receiving end. This also builds your understanding of the process.

• Step 1: Don't Ignore It. This is the worst thing you can do. Ignoring an LBA will likely lead to the creditor pursuing a Court action and, in due course, a default court judgment being entered against you, which can seriously damage your credit rating and lead to enforcement action.
• Step 2: Check the Details. Carefully review the letter. Is the amount correct? Do you recognise the debt and the claimant? Check the evidence they have provided.
• Step 3: Respond Within the Deadline. You should respond. Acknowledge the letter and clearly state your position. You might realise non-payment was an oversight and pay, or admit the debt and propose a payment plan, or dispute the debt and explain why, or request more information if the claim is unclear.
• Step 4: Seek Advice. For any dispute that is complex or involves a large sum of money, it's wise to seek professional advice. According to experts at Citizens Advice, responding to a Letter Before Action promptly and correctly is essential.

Frequently Asked Questions (FAQs)

How long is a letter before action valid for?

A Letter Before Action doesn't have a strict expiry date. However, the court expects you to issue proceedings within a reasonable timeframe after the deadline in your letter passes. If you wait for many months, a Judge might question the delay and could ask you to send a fresh LBA before proceeding.

Can I send a Letter Before Action by email?

Yes, you can send it by email, but proving it was received can be challenging if the debtor claims they never saw it. You are always recommended to send a copy by post and the most reliable method is still a tracked postal service, like Royal Mail Signed For. This provides you with a definitive record that the letter was delivered to their address.

What's the difference between a Letter Before Action and a Late Payment Reminder?

A payment reminder is an informal, friendly nudge to pay an invoice. An LBA is a formal legal document. It signals the start of the official pre-action process and is a mandatory prerequisite for starting a court claim. It carries significant legal weight that a simple reminder does not.

Can I claim my legal costs for sending the LBA?

For business-to-business debts, the late payment legislation allows you to claim a fixed sum as compensation for debt recovery costs, which can help cover the expense of preparing and sending the letter. However, you generally cannot claim the specific solicitor's fees for drafting the LBA at this pre-action stage.

Is a free Letter Before Action template from the internet safe to use?

It's risky. Free templates are often too generic to cover your specific situation. They might not be compliant with the latest version of the Pre-Action Protocol, which can change. Using a flawed template offers no protection and could jeopardise your entire claim if you get it wrong. Garfield's LBAs are so inexpensive and quick to generate that they are a genuine 'no brainer'.
