If a business customer has not paid your invoice and chasing has produced nothing, a letter before action is the next step. It is one of the most important things you can do before taking any formal action — and it is something you can do yourself, without a solicitor.
Done properly, a letter before action signals that you are serious, puts the debtor on formal notice, and sometimes produces payment on its own. It also puts you in the right legal position for whatever comes next — whether that is a neutral decision process or a court claim.
A letter before action — sometimes called an LBA or a letter before claim — is a formal written notice sent to a debtor before you take formal proceedings. It tells them clearly that you intend to pursue the debt through a formal process if they do not pay within a specified period.
It is not the same as a final demand, even though the two are often confused. A final demand is a strong payment request — the last in a series of chasing letters. A letter before action is a formal legal step that signals the end of the chasing phase and the beginning of the formal recovery process.
Courts in England and Wales expect to see that a letter before action has been sent before a claim is issued. Failure to send one — or sending one that does not meet the basic requirements — can result in cost penalties even if you win your case. Getting this step right matters.
A letter before action does not need to be long or complicated. It does need to be clear, complete, and firm. Include the following:
Send it in a way that creates a record of delivery. Email with read receipt is acceptable and creates a clear timestamp. A recorded or tracked letter adds a physical paper trail. For higher-value debts, sending by both email and recorded post is a sensible precaution.
Keep a copy of everything — the letter itself, the delivery confirmation, and any response you receive. This documentation will be important if the matter proceeds to a neutral decision process or a court claim.
If the deadline passes with no payment and no response, you have a clear choice to make about next steps.
For straightforward unpaid invoices where the debt is not contested, a court claim through the small claims track — for debts up to £10,000 — is one option. For larger debts, or where the other side has disputed the invoice, the small claims track is either unavailable or unsuitable.
For invoices under £150,000 — whether disputed or simply unpaid — a private neutral decision process is often the more practical route. It is faster than court, costs a fixed fee, produces a binding outcome, and keeps the matter entirely private. See our full guide on recovering unpaid invoices without going to court.
At Dispute Neutral, a binding decision is issued within 10 business days of the matter being ready. There is no hearing. Neither party needs a solicitor. And both sides know exactly what the process will cost before they agree to it.
A response is not always a resolution. Sometimes a debtor responds to a letter before action with a partial payment, a promise to pay, a request for more time, or a dispute about the invoice.
Each of these needs a different response. A partial payment should be acknowledged but should not be treated as full settlement unless you explicitly agree to it. A promise to pay should be confirmed in writing with a specific date. A request for more time should be considered carefully — it may be genuine, or it may be a stalling tactic.
A dispute about the invoice is the most important response to handle carefully. If the debtor raises a genuine question about the work, the amount, or the contract, you are now dealing with a disputed debt rather than a simple refusal to pay. Statutory interest and fixed compensation are generally not claimable on genuinely disputed invoices. A neutral decision process that resolves the underlying disagreement becomes the most appropriate next step.
The most effective way to handle a letter before action situation is to have already agreed — in your standard terms of business or engagement letter — how any dispute will be resolved if it arises.
Businesses and professionals that include a Dispute Neutral clause in their terms ensure that if an invoice goes unpaid and a letter before action produces no result, the next step is already agreed. There is no need to persuade a reluctant debtor to engage with a formal process. The process is already part of the contract.

No. A letter before action does not need to be drafted by a solicitor. It needs to be clear, complete, and firm — stating the amount owed, the deadline for payment, and the specific next step you intend to take. Many businesses write their own letters before action without any legal assistance. If the matter subsequently proceeds to a neutral decision process or a small claims court claim, you do not need a solicitor for those steps either.
Seven to fourteen days is the standard period for most commercial debt letters before action. For larger or more complex debts, some pre-action protocols suggest longer periods — up to 30 days. The key is to be specific: state an exact date, not just a number of days. This avoids any ambiguity about when the deadline falls and when you are entitled to take the next step.
Yes. Email is widely accepted as a valid method of sending a letter before action, provided you can demonstrate it was sent and — ideally — received. Use an email that generates a read receipt or delivery confirmation, and keep a copy of the sent email with its timestamp. For higher-value debts, follow up with a recorded postal copy as well to create a complete paper trail.
This is why delivery method matters. If you have sent by tracked post or email with delivery confirmation, you have evidence that the letter was sent and received. If the debtor claims non-receipt despite evidence of delivery, that position is unlikely to carry much weight in a subsequent neutral decision process or court claim. Keep your delivery records carefully and include them in any subsequent submissions.
If your letter before action has produced no payment and no satisfactory response, Dispute Neutral offers a private, fixed-fee route to a binding outcome — without court, without solicitors, and without the wait.
