Direct Answer

A letter before action (LBA) is a formal written demand sent before starting legal proceedings. It must clearly state the amount owed, give a payment deadline (typically 14 days), and warn that court action will follow. Courts expect it to be sent before any claim is issued.

Why the Letter Before Action Matters More Than You Think

A letter before action is more than a courtesy — it's a procedural cornerstone of UK debt recovery. Courts expect you to attempt resolution before issuing proceedings, and failing to send one correctly can cost you in the courtroom even if you win the case.

But there's another equally important reason: it works. Research consistently shows that a significant proportion of debts are paid — or a payment plan is agreed — at the letter before action stage, before anyone sets foot in a court.

A professional, correctly structured LBA signals to the debtor that you are serious, organised, and prepared to go further if necessary. That tone alone often prompts payment.

What Must Be Included in a Letter Before Action

Your full name and address

Or your business name and registered address.

The debtor's full name and address

Use the address where they can be formally served.

Clear description of the debt

Invoice numbers, dates, amounts owed, and what they relate to.

Payment deadline

Typically 14 days from the date of the letter.

Statement of intent

Make clear you will issue court proceedings if payment is not received.

Payment details

Include your bank account details so payment can be made immediately.

The 4-Step Process for Sending an Effective LBA

01

Gather Your Evidence First

Before writing the letter, compile all relevant documents: invoices, contracts, delivery notes, and a timeline of communications. Your LBA is only as strong as the evidence behind it.

02

Write Clearly and Professionally

Avoid emotional language. Be direct, factual, and specific. State the exact amount owed, reference relevant invoice numbers, and be unambiguous about your intentions.

03

Send It Properly

Send by recorded delivery post and by email. This gives you proof of delivery on both channels. Keep the postal receipt.

04

Record the Response Deadline

Note the 14-day deadline in your calendar. If payment or a credible response is not received by that date, proceed to issuing a court claim.

What Happens if the Debtor Doesn't Respond?

Winning a case does not guarantee payment — enforcement is essential.

If the debtor ignores your LBA, you move to court proceedings — and then, if necessary, enforcement. Each stage adds pressure and legal weight.

Once the deadline passes without response, issue a county court claim. The LBA serves as the documented first step in your pre-action protocol — judges will review it if the case goes to a hearing.

Common Letter Before Action Mistakes

  • Sending it with the wrong amount — always double-check the total including interest
  • Using threatening or aggressive language that courts will view unfavourably
  • Failing to keep copies of all correspondence and proof of postage
  • Not giving a clear deadline — "as soon as possible" is not sufficient
  • Waiting too long before sending one — act as soon as a payment becomes overdue

DIY Letter Before Action vs Using a Solicitor

A properly drafted LBA does not require a solicitor. In fact, a solicitor-headed letter may actually reduce the chance of recovery — some debtors become defensive when they see legal letterheads and respond to human, professional correspondence more constructively.

A structured debt recovery tool can simplify this process — generating your letter before action in the correct format, with all required content, without expensive legal fees.
