Final notice before legal action: template and what to include
When friendly reminders haven't worked, a final notice draws the line: one last deadline and a clear consequence. Done well, it gets most stubborn invoices paid without ever going near a court. Here's what to write and when to send it.
When to send it
Send a final notice after the normal sequence has run its course — usually around 30 days overdue, after a heads-up and three reminders (see the 5-step schedule). Sending it earlier tends to damage relationships over invoices that were simply stuck.
There are two levels:
- Final notice email — the last step of your reminder sequence. Firm, short, with a deadline.
- Letter before action — a formal letter you send if you're genuinely prepared to start a court claim or use a collection agency.
What a final notice must include
- The facts: invoice number, date, amount, original due date and how many days overdue.
- History: that you've already sent reminders (dates help).
- The full amount now owed, including any late payment interest and compensation you're entitled to — work it out with the late payment interest calculator.
- A specific deadline, as a date, not “within a week”.
- The consequence if it's missed. Only state consequences you'll actually carry out.
- How to pay — a payment link or bank details.
- An invitation to talk if there's a genuine problem. It shows you're reasonable, which matters if this ever reaches a court.
Template 1: final notice email
Template 2: letter before action (England and Wales)
Use this only if you're prepared to follow through. Send it by email and by post or recorded delivery, and keep copies.
The interest and compensation lines only apply to business clients — see late payment interest in the UK. For consumers, include only charges your contract allows.

| Situation | Typical deadline |
|---|---|
| Final notice email | 7–14 days |
| Letter before action to a company (England & Wales) | A reasonable period — often 14 days |
| Letter before action to an individual or sole trader (England & Wales) | 30 days, with the information sheet and reply form the protocol requires |
When your client is an individual — including a sole trader — the Pre-Action Protocol for Debt Claims applies. It requires extra documents with the letter and gives the debtor 30 days to reply. Between companies, the court's general Practice Direction on Pre-Action Conduct applies. Scotland and Northern Ireland have their own procedures.
If the deadline passes
- Pause the work if you said you would. Following through is what makes your next notice credible.
- Try mediation. It's often faster and cheaper than court — GOV.UK explains the options.
- Use a collection agency for business debts. They usually take a percentage of what they recover.
- Make a court claim. In England and Wales you can claim money online through GOV.UK. Smaller claims (up to £10,000) go to the small claims track, which is designed for people without lawyers. Court fees apply and can usually be added to your claim.
Before going this far, it's worth one phone call. Hearing a real person say “I'll have to start a claim on Friday” settles a surprising number of debts.
FAQ
What is a final notice for an unpaid invoice?
The last reminder before you escalate. It restates the invoice, the amount and how late it is, sets a final deadline and says exactly what will happen if it is missed, such as late payment interest, paused work or court action.
How long should I give in a final notice?
For a final reminder email, 7 to 14 days. For a formal letter before action in England and Wales, give a company a reasonable time (often 14 days) and an individual or sole trader 30 days, as the Pre-Action Protocol for Debt Claims requires.
What is a letter before action?
A formal letter sent before starting a court claim. It sets out what is owed and why, and gives the debtor a deadline to pay or respond. Courts in England and Wales expect it, and skipping it can affect costs.
Can I add interest and fees in a final notice?
Yes, if you are entitled to them. For business-to-business invoices in the UK and EU, statutory interest and fixed compensation apply by default. State the amounts so the debtor knows the full figure.
Do I need a lawyer to send a letter before action?
No. Many small businesses send their own. A solicitor's letter can carry more weight for large debts or difficult clients, but it costs money that may not be recoverable.
