Final Demand Ignored? Your Options at a Glance

Why businesses ignore final demands

Before deciding what to do next, it helps to understand why your final demand may have been ignored.

Sometimes it is deliberate — the debtor is hoping you will give up or go away. Sometimes it is a sign that the other side disputes the invoice and doesn't know how to say so. Occasionally it is a cash flow problem and they are stalling.

The reason matters, because it shapes the right next step. A debtor who disputes the invoice needs a different approach from one who is simply refusing to pay.

1. Send a formal letter before action

A letter before action (sometimes called an LBA) is a formal written notice that tells the debtor you intend to take further steps if they do not pay within a set period: 14 days for a business, or 30 days if the debtor is a sole trader or other individual (under the Pre-Action Protocol for Debt Claims).

It is not the same as a final demand. An LBA signals that you are serious and prepares the ground for any next step, whether that is a neutral decision process or a court claim. Courts also expect to see that you have sent one before issuing a claim.

If you have not sent an LBA yet, this is usually the right immediate step.

2. Consider whether the invoice is disputed

If the debtor has at any point raised a question about the invoice — the work done, the amount, the contract terms — you may be dealing with a disputed debt rather than a simple refusal to pay.

This matters because a disputed debt needs a process that can actually resolve the disagreement, not just chase payment. A dispute does not remove your right to statutory interest and fixed compensation under the Late Payment of Commercial Debts (Interest) Act 1998: if the debt turns out to be owed, they still run from the original due date.

3. Use a private neutral decision service

If you want a binding outcome without the cost and delay of court, a private neutral decision service is worth considering.

Both parties agree to appoint an independent neutral, an independent lawyer with at least 15 years' practical experience, acting as an expert, not an arbitrator, who reviews the contract, the documents, and the written submissions from both sides, then issues a binding decision. The whole process is document-based and private.

At Dispute Neutral, decisions are issued within 10 business days of the matter being ready. There are no hearings, no solicitors required, and fees are fixed by band. For disputes between businesses up to £150,000, including unpaid invoices, trade debts and professional fees, it is designed to be a practical and proportionate route.

4. Issue a money claim through the courts

If the other options are not suitable, you can issue a claim through the courts. For claims up to £10,000 in England and Wales (£5,000 in Northern Ireland), this usually means the small claims track. For larger amounts, the process is more involved and legal costs increase significantly.

Court is a legitimate option, but it carries real disadvantages: it takes time, it is public, costs can escalate, and even a judgment in your favour does not guarantee payment. Many businesses find that the process costs more — in time and money — than the debt itself.

5. Use a debt collection agency

Debt collection agencies chase payment on your behalf, typically in exchange for a percentage of the recovered amount. They can be effective for straightforward unpaid invoices, but they have no power to resolve a dispute, and their cut reduces what you actually recover.

What to do right now

If your final demand has been ignored, here is a practical sequence to follow:

1. Send a formal letter before action if you have not already done so
2. Give the debtor a clear deadline: 14 days for a business, 30 days for a sole trader or other individual
3. Decide whether the debt is disputed or simply unpaid
4. Choose the right next step based on that: a neutral decision process for disputed debts, court or a collection agency for straightforward refusals

Acting promptly matters. The longer a debt remains unpaid, the harder recovery becomes.

What is the difference between a final demand and a letter before action?

A final demand is a strong payment request, often the last in a series of chasing letters. A letter before action is a formal legal step that puts the debtor on notice that proceedings or another formal process will follow if they do not pay. Courts expect to see an LBA before a claim is issued.

Can I charge interest on an invoice that has been ignored?

Yes, in most cases. Under the Late Payment of Commercial Debts (Interest) Act 1998, you can claim statutory interest at 8% above the Bank of England base rate (11.75% a year for debts falling due in 2026) on overdue commercial invoices. You can also claim fixed compensation of £40, £70, or £100 depending on the size of the debt. These rights apply automatically to business-to-business contracts; a contract can only replace them with its own remedy if that remedy is substantial.

Do I need a solicitor to recover an unpaid invoice?

Not necessarily. For straightforward debts, many businesses handle small claims themselves. For disputed invoices, a private neutral decision service like Dispute Neutral offers a binding resolution process without either party needing a solicitor.

How long does a neutral decision process take?

At Dispute Neutral, a binding decision is issued within 10 business days of the matter being ready for decision. That means once both parties have submitted their documents and written submissions, you have a binding outcome within two working weeks, compared with a median of 41.0 weeks for a small claim to reach trial (HMCTS civil justice statistics, April to June 2026). Both parties must agree to use the process.

If your final demand has been ignored and the other side will agree to a private decision, Dispute Neutral may be the right place to start.
