Letter before action: Costs, rules, and sending by email

Last updated: 6 January 2026

Before you file a court claim, you need to send a Letter Before Action. But how much does it cost, what are the legal rules, and can you just email it?

How much does it cost?

DIY (do it yourself):

  • Postage: £3-5 (Recorded Delivery or Signed For)
  • Your time: 4-6 hours (research, drafting, formatting)
  • Risk: Missing legal requirements or using the wrong tone

Solicitor:

  • Cost: £150-£400 just for the letter
  • Not recoverable in small claims court (you're out of pocket even if you win)
  • Often overkill for straightforward debts under £10,000

Garfield:

  • Fixed, transparent fee

For any letter sent to an individual, it must comply with the Pre-Action Protocol for Debt Claims. Courts take this seriously: if you don't follow the rules, your claim can be dismissed, or worse, you could be ordered to pay the defendant's legal costs.

What you must include:

  1. Your details (name, address, contact info)

  2. Their details (correct legal name and address; check Companies House for businesses)

  3. Amount owed with full breakdown (original debt + interest + fees)

  4. What the debt is for (invoice number, goods/services provided, date)

  5. Specific deadline (typically 30 days from the date they receive it)

  6. Payment methods (bank details, payment link)

  7. Warning of consequences if they don't pay (court action, additional fees)

  8. Required forms (if claiming from an individual or sole trader only):

    • Information Sheet - explains the debtor's rights and next steps
    • Reply Form - standard form for the debtor to respond
    • Financial Statement Form - income and expenditure form

    These three forms are mandatory under the Pre-Action Protocol for Debt Claims when pursuing individuals or sole traders. They're not required for limited companies. Get the official forms from the Pre-Action Protocol for Debt Claims.

What you must do:

  • Provide sufficient information so they understand the claim
  • Give reasonable time to respond (30 days)
  • Consider any genuine disputes before rushing to court

If they respond saying they dispute the debt, you can't just ignore that and file a claim. You need to engage with their dispute or risk the court penalizing you.

Can you send it by email?

Short answer: Email alone isn't enough.

Courts require Letters Before Action to be sent by post. An email can be ignored, deleted, or claimed to have gone to spam.

What happens if you get it wrong?

If your Letter Before Action doesn't comply with the Pre-Action Protocol:

  • The court might dismiss your claim
  • You could be ordered to pay the defendant's costs
  • It delays your recovery and costs you more money

Courts expect you to have followed the rules properly before filing.
