Get paid what you’re owed.
Plus statutory interest and compensation.
Client gone quiet on your invoice? Under the Late Payment of Commercial Debts (Interest) Act 1998 you can charge 8% above base on B2B debts, plus £40–£100 fixed compensation. CourtPilot drafts the letter, the particulars and walks you through MCOL.
We help you prepare the documents and file them yourself — you’re always the claimant on the record. Not a law firm, no legal advice given.

Five checks.
If most are yes, you’ve got a claim.
Unpaid-invoice claims are some of the cleanest small-claims cases — the debt is documented, the deadline is documented, and the statute hands you interest and compensation on a plate.
Late Payment Act,
baked in.
Generic invoice chasers don’t cite the statute. CourtPilot drafts to the Late Payment of Commercial Debts (Interest) Act 1998 — names the interest rate, the fixed compensation and the 30-day deadline.
Re: Invoice 2026-041 · £4,800 outstanding
Dear Ms Doyle,
I write before issuing a claim in the County Court Money Claims Centre. Invoice 2026-041 for £4,800 + VAT covering design services from 1 February to 31 March 2026 fell due on 14 April 2026 and remains unpaid.
Under the Late Payment of Commercial Debts (Interest) Act 1998, statutory interest at 8% above base and fixed compensation of £70 are now claimed in addition to the principal sum…
Solicitors are expensive per invoice.
CourtPilot is one fee.
A solicitor charging hourly on a £3,000 invoice eats the recovery — and on the small-claims track those fees aren’t recoverable. CourtPilot is one flat price covering letter, particulars and bundle.
£9.97 today. £97 if it goes the distance.
Send the letter first. Most disputes settle once a proper LBA lands. If yours doesn’t, the £9.97 comes off the toolkit — same total either way.
The bits people always ask.
Can I charge interest on an unpaid invoice?+
Yes. Under the Late Payment of Commercial Debts (Interest) Act 1998 you can charge 8% statutory interest above the Bank of England base rate on B2B invoices. You can also claim fixed compensation of £40–£100 depending on the invoice size. Even if it isn’t in your terms, the statute kicks in by default.
What if there is no written contract?+
You can still claim. If the client accepted the work and you have evidence of the agreement — emails, messages, purchase orders, or just the fact they used your services — that is sufficient. The invoice itself is evidence of the debt.
What about the Late Payment of Commercial Debts Act?+
It gives businesses the right to charge statutory interest at 8% above base on late B2B payments. It also entitles you to fixed compensation: £40 for debts up to £999.99, £70 for debts up to £9,999.99, and £100 for debts of £10,000 or more — per invoice.
Should I send a Letter Before Action first?+
Yes. The court expects you to follow the Pre-Action Protocol for Debt Claims, which requires a formal LBA giving the debtor 30 days to pay. CourtPilot generates this for you. A non-trivial share of invoices get paid at this stage — naming the Act helps.
Can I claim from a client that’s gone into administration?+
If the company is in administration or liquidation, you can’t issue a court claim without permission. You register as a creditor instead. Check the company status on Companies House before you start.
