Is the Letter Before Action legally valid?
Yes. It follows the Pre-Action Protocol for Debt Claims. Courts expect a Letter Before Action before proceedings begin. Experi's template meets this requirement.
What is statutory interest?
Under the Late Payment of Commercial Debts Act 1998, you're entitled to charge interest at 8% above the Bank of England base rate on overdue invoices between businesses. You're also entitled to a fixed compensation fee of £40, £70, or £100 depending on the invoice value.
What if the client ignores the LBA?
Your next step is small claims court (for invoices up to £10,000) or the Money Claim Online (MCOL) service. Experi's evidence pack gives you everything you need to file the claim.
Does this work for invoices to individuals (B2C)?
Statutory interest under the Late Payment Act applies to B2B transactions. For B2C, different rules apply. Experi's tools are primarily designed for businesses invoicing other businesses or sole traders.
