Learn how to write a demand letter for payment with a free UK template, step-by-step guidance, and tools to help you recover money owed quickly and correctly.

Demand letter for payment template

When someone owes you money and isn’t paying, sending a formal demand letter is often the most effective first step you can take. A well-written demand letter signals that you are serious about recovering the debt, gives the other party a clear deadline to respond, and — crucially — creates a paper trail that can support your case if you later decide to take the matter to the small claims court.

This guide explains what a demand letter for payment is, what it must include, how to write one step by step, and how to use ClaimsPilot’s free tools to make the process as straightforward as possible.

What is a demand letter for payment?

A demand letter for payment (sometimes called a “letter before action” or “letter before claim” in the UK) is a formal written notice sent to a person or business that owes you money. It sets out:

• What is owed and why
• How much you are claiming, including any interest
• A reasonable deadline by which payment must be made
• What action you intend to take if payment is not received

In England and Wales, sending a letter before action is not just best practice — it is a pre-action requirement under the Civil Procedure Rules (CPR). Courts expect claimants to give the other party a fair opportunity to settle the dispute before proceedings begin. Failing to send one could count against you when costs are considered.

You can read more about pre-action protocols on the Ministry of Justice’s Civil Procedure Rules pages.

When should you send a demand letter?

A demand letter is appropriate in a wide range of situations, including:

• A client or customer has not paid an invoice
• A landlord has not returned a tenancy deposit
• A trader has not completed work or refunded money for poor service
• A person owes you money following a private arrangement
• A business has failed to deliver goods you have already paid for

Before drafting your letter, it is worth giving the other party a brief, informal reminder — a phone call or a chaser email — just in case the non-payment is a genuine oversight. If that produces no result, a formal demand letter is your next step.

For most consumer disputes, the deadline you set in your letter should give the recipient 14 days to respond. Business-to-business disputes typically allow 14–30 days, depending on the complexity of the claim. Courts generally regard 14 days as a reasonable minimum.

What to include in your demand letter

A strong demand letter needs to be clear, professional, and complete. Here is what every letter should contain:

Your details

Include your full name (or business name), address, email address, and phone number at the top of the letter. If you are writing on behalf of a business, use headed paper or include your company details clearly.

The recipient’s details

Address the letter to the correct legal name of the individual or business. If you are writing to a limited company, use the registered company name (you can check this on Companies House).

The date

Always include the date the letter is written. This is important because it establishes when the deadline countdown begins.

A clear summary of the debt

Explain concisely how the debt arose. For example: “On [date], I engaged your company to carry out roofing work at [address]. The agreed price was £1,200. The work was completed on [date] and an invoice (number: [X]) was issued on [date]. Despite reminders on [dates], the invoice remains unpaid.”

The total amount claimed

State the exact amount you are claiming, broken down where possible. This might include:

• The principal sum owed
• Any statutory or contractual interest
• Any reasonable costs you have already incurred

The Late Payment of Commercial Debts (Interest) Act 1998 allows businesses to charge 8% above the Bank of England base rate on unpaid invoices in business-to-business transactions. You can use the ClaimsPilot interest calculator to work out exactly how much interest has accrued.

Your deadline

State clearly when you expect payment or a written response — for example, “within 14 days of the date of this letter.” Be specific.

What happens if the deadline is not met

Make clear that you intend to commence proceedings in the County Court (or the small claims court, depending on the amount) if the matter is not resolved. You do not need to be aggressive — a simple, factual statement is far more effective.

Signature

Sign the letter and print your name beneath your signature.

Letter before action — formal demand for payment

Dear [Name],

I am writing to formally request payment of the outstanding sum of £[amount], which has been owed since [date].

[Briefly describe how the debt arose — e.g., unpaid invoice, failure to return deposit, goods not delivered, etc.]

Despite [previous reminders on (dates) / the invoice becoming overdue], this amount remains unpaid. I am therefore writing to request that you settle this debt in full within 14 days of the date of this letter — by [specific deadline date].

The total amount now owed is £[amount], including interest calculated at [X]% from [date] to [date].

If I do not receive payment or a satisfactory written response by [deadline date], I intend to commence proceedings in the County Court without further notice. Should I be required to do so, I will also seek recovery of court fees and any further interest to which I am entitled.

I hope we can resolve this matter without the need for legal proceedings.

Yours sincerely,

[Your signature]

[Your printed name]

How to send your demand letter

Once your letter is ready, how you send it matters. We recommend:

1. Send it by email and post. Email provides an immediate, timestamped record; first-class post (or recorded delivery) provides proof of physical delivery.

2. Keep a copy. Save the letter and any email confirmation in a dedicated folder.

3. Follow up in writing if there is no response. If the deadline passes without a reply, send a brief follow-up confirming you received no response and that you are proceeding with your claim.

Avoid sending angry or threatening messages alongside your letter. Courts take a dim view of aggressive or unreasonable behaviour from either party, and anything you write could be disclosed in proceedings.

What to do if they don’t pay after the deadline

If the deadline passes and you have still not received payment or a meaningful response, you have several options:

• File a claim through the County Court. For claims up to £10,000 in England and Wales, you can use the small claims track, which is designed to be accessible without a solicitor.
• Use Money Claim Online (MCOL). The government’s MCOL service allows you to submit and manage claims online.
• Consider mediation. The Small Claims Mediation Service is a free service offered by HMCTS that can help resolve disputes before a court hearing.

Before filing, double-check your claim amount, ensure your demand letter is in order, and use the ClaimsPilot interest calculator to confirm the interest figure you are claiming is accurate.
