Before you can take a tenant to court for unpaid rent or other debts, you must send a Letter Before Action (LBA). This isn't just good practice—it's a legal requirement under the Pre-Action Protocol for Debt Claims. Get it wrong, and the court may penalise you on costs even if you win.
Need court-ready documents? Our Money Claim Pack generates a compliant Letter Before Action tailored to your specific claim.
What is a Letter Before Action?
A Letter Before Action (sometimes called an LBA or "letter of claim") is a formal letter you send to a debtor before starting court proceedings. It gives them one final chance to pay or propose a payment plan before you issue a claim.
For landlords, you'll typically send an LBA when a tenant owes you:
- Unpaid rent arrears
- Property damage costs exceeding the deposit
- Cleaning costs not covered by the deposit
- Unpaid utility bills they were responsible for
- Early termination fees
- Any other contractual debt
Why is the LBA Required?
The Pre-Action Protocol for Debt Claims requires creditors to send a compliant letter before starting court proceedings. The protocol aims to:
- Give debtors a chance to pay without court action
- Encourage early settlement and payment plans
- Ensure debtors understand the claim against them
- Reduce unnecessary court cases
If you don't follow the protocol, the court may:
- Stay (pause) your claim until you comply
- Refuse to award you costs even if you win
- Order you to pay the defendant's costs
What Your LBA Must Include
A compliant Letter Before Action must contain specific information:
Essential Elements:
- ✓ Your full name and address (the creditor)
- ✓ The debtor's full name and address
- ✓ The amount owed (itemised breakdown)
- ✓ How the debt arose (e.g., tenancy agreement)
- ✓ Interest claimed (if any)
- ✓ A deadline to respond (minimum 30 days)
- ✓ What happens if they don't respond
- ✓ Information about debt advice services
- ✓ A reply form or financial statement

How to Send Your Letter Before Action
How you send the letter matters for evidence purposes:
- First class post - Standard method, keep proof of posting
- Recorded delivery - Provides tracking but tenant may refuse
- Email - Acceptable if you have their email address, keep sent copy
- Hand delivery - Have a witness and note date/time
The 30-day response period starts from when they receive the letter (or when it's deemed delivered—typically 2 business days after posting).
What Happens After Sending the LBA
After sending your Letter Before Action, several things might happen:
Best Case: They Pay
The tenant pays in full. Matter resolved—no court needed.
They Propose Payment Plan
Consider if it's reasonable. You can negotiate or reject and proceed to court.
They Dispute the Debt
Review their reasons. If you still have a valid claim, proceed to court.
No Response
After 30 days, you can issue your court claim via MCOL or N1 form.

How long must I wait after sending the LBA?
You must give the debtor at least 30 days to respond from the date they receive the letter. If they ask for more time to get debt advice, consider allowing up to 30 additional days.
Can I claim interest in my LBA?
Yes. You can claim statutory interest at 8% per year on debts. Calculate from when the debt was due until your claim date. Include the calculation in your letter.
What if the tenant has moved and I don't have their address?
Try to find their current address through forwarding mail, references, guarantors, or tracing services. If unsuccessful, you may still be able to proceed with court action using their last known address.
Do I need a solicitor to send an LBA?
No. Landlords can send Letters Before Action themselves. The letter doesn't need to be from a solicitor to be valid—it just needs to contain the required information.
