What Is a Demand Letter?
A demand letter — sometimes called a letter of demand or a pre-action letter — is a formal written notice sent to a person or business demanding payment, action, or resolution of a dispute. It puts the recipient on notice that legal proceedings will follow if they fail to respond within the deadline set.
In England and Wales, sending a demand letter before issuing a small claim is not just good practice — it is required under the Pre-Action Protocols. Courts expect both parties to have attempted resolution before filing a claim.
Demand Letter vs Letter Before Action — What's the Difference?
In practice, the terms are used interchangeably in the UK. A Letter Before Action (LBA) is the formal legal name used in court proceedings. A demand letter is the broader term covering any written demand for payment or performance before legal action. Both serve the same purpose: putting the other party on notice and satisfying the Pre-Action Protocol requirement.
What Must a Demand Letter Include?
- Your full name and address — as the party making the demand
- Recipient's full name and address — use the registered address for companies
- Clear description of the dispute — what happened, when, what was agreed, and what went wrong
- The amount demanded or action required — principal sum, interest, and any reasonable costs
- Supporting documents referenced — invoices, contracts, receipts, correspondence
- A clear deadline for response — typically 14 days for businesses, 30 days for individuals
- Consequences of non-response — you will issue court proceedings without further notice

When Should You Send a Demand Letter?
Send a demand letter as soon as informal attempts to resolve the dispute have failed. Common situations include:
- An unpaid invoice or debt that has not been settled after chasing
- Goods or services paid for but not delivered or completed
- A contractor or tradesperson who has done poor or incomplete work
- A landlord who has not returned a tenancy deposit
- Property damage caused by a neighbour or third party
- A business that has breached a contract
Frequently Asked Questions
Yes, in most small claims cases. The Pre-Action Protocol requires you to notify the other party of your intention to sue and give them a reasonable opportunity to respond before you file a claim. Courts can impose cost penalties on claimants who skip this step, even if they win.
14 days is standard for business-to-business disputes. For individuals or more complex matters, 30 days is more appropriate. The key test is whether you gave a "reasonable" time — courts will take this into account if the matter proceeds to a hearing.
If the deadline passes with no payment or satisfactory response, you can file your court claim immediately. Your demand letter becomes evidence that you followed the Pre-Action Protocol. ClaimsPilot can take you straight from letter to claim filing with your case data already populated.
Send by recorded post (Royal Mail Signed For or Special Delivery) so you have proof of delivery. Email alone may not be sufficient evidence that the letter was received. Ideally, send both — email for speed and recorded post for proof.
