Taking an unpaid invoice to small claims court — is it worth it?

The honest cost-benefit, before anything else

Court is the right tool for some unpaid invoices and a waste of time for others, and it's worth being clear-eyed about which yours is before you spend a penny. The small claims track works brilliantly when three things are true:

• The debt is clear. The client accepted the work (or never complained about it), the invoice matches what was agreed, and there's no genuine dispute — they just haven't paid.
• The debtor is solvent. A trading company or an individual with income and assets. A judgment against an empty shell is a piece of paper.
• You have a paper trail. A contract or email agreement, the invoice, proof the work was delivered, and your chase correspondence.

When those hold, the economics are good: fees are modest and recoverable, you don't need a solicitor, and the overwhelming majority of straightforward invoice claims end in default judgment or payment before any hearing. When they don't hold, think twice:

• The debtor is insolvent or dissolving. If the company is in liquidation, administration, or has been struck off, you join the queue of unsecured creditors — court action gains you little.
• The work is genuinely disputed. If the client has a documented, arguable complaint about what was delivered, the claim becomes a contested case rather than a debt collection exercise. Winnable, but slower and less certain.
• The amount is tiny. A £150 invoice carries a £35 issue fee and several hours of your time. Recoverable if you win, yes — but a final firm letter is often the more proportionate move.

Before you file: one letter and two checks

First, the letter. The courts expect you to have sent a formal Letter Before Action (also called a letter before claim) and given the debtor a reasonable period — at least 14 days for a business debtor — to respond. Skipping it can count against you on costs even if you win. It's also, in practice, the document most likely to get you paid without filing anything: see our guide to writing a Letter Before Action.

Second, the checks. Before paying a court fee, spend five minutes on the free Companies House register (if the client is a limited company): confirm the company still exists, that you have its exact registered name and registered office address, and that it isn't in liquidation, administration, or flagged for strike-off. Suing a dissolved company is suing nobody. For sole traders, confirm you have a current trading or home address — the claim form has to be served somewhere real.

Money Claim Online (MCOL), step by step

For fixed money claims up to £10,000 in England and Wales, the government runs an online service — Money Claim Online, with a newer equivalent at moneyclaims.service.gov.uk — that lets you issue a County Court claim from your laptop. No solicitor, no paper forms, no court visit for an undefended claim.

1. Register for the service via gov.uk ("make a court claim for money") using a Government Gateway sign-in.
2. Enter the defendant's details — the exact registered name and address you verified above.
3. Write your particulars of claim. This is a short, factual statement, not legal prose. Cover: what you supplied and when; the invoice number, date, and amount; the agreed payment terms; that payment was not made; and that you claim statutory interest and the fixed sum under the Late Payment of Commercial Debts (Interest) Act 1998. Plain chronology beats legalese.
4. Add statutory interest. For B2B invoices you're entitled to interest at 8% above the Bank of England base rate — currently 11.75% per annum — from the day after the due date, accruing daily until judgment or payment. State the daily rate in the particulars so interest keeps running after filing. Our calculator gives you the exact figures.
5. Add the fixed debt recovery sum — £40 for debts under £1,000, £70 for £1,000 to £9,999.99, £100 for £10,000 and over. It's a statutory entitlement on every overdue B2B invoice, so claim it.
6. Pay the issue fee by card and submit. The court serves the claim on the defendant for you.

What it costs

The issue fee depends on the total amount claimed (invoice plus interest plus the fixed sum). At the time of writing the bands for an online money claim are:

• Up to £300 — £35
• £300.01 to £500 — £50
• £500.01 to £1,000 — £70
• £1,000.01 to £1,500 — £80
• £1,500.01 to £3,000 — £115
• £3,000.01 to £5,000 — £205
• £5,000.01 to £10,000 — £455

If the claim is defended and reaches a hearing, a hearing fee of between £27 and £346 (again scaling with claim size) is payable closer to the date. Fees are revised periodically — check the current figures on gov.uk before you file. The key point: court fees are added to your claim, so if you win, the debtor pays them, not you.

What happens after you file

The defendant has 14 days from service to respond (28 if they file an acknowledgment of service first). From there, one of three things happens:

• Silence. If they don't respond at all, you request default judgment online — a County Court judgment (CCJ) for the full amount, interest, and fees, with no hearing. For ignored invoice debts this is the most common outcome.
• Admission. They admit the debt, in full or in part, sometimes asking to pay by instalments. You can accept or ask the court to set the rate.
• Defence. They contest the claim. Both sides complete a directions questionnaire, the court offers free telephone mediation, and failing that the case is listed for a small claims hearing — short, informal, no wigs, designed for unrepresented parties.

It's worth saying plainly: most cases never get near a hearing. A large share of debtors pay when the claim form lands, because a CCJ on the register wrecks a company's credit for six years (unless paid within a month of judgment). The claim itself is the leverage.

If they still don't pay after judgment

A judgment doesn't transfer money by itself. If the debtor ignores it, you apply — for a further recoverable fee — to enforce:

• Warrant of control. County Court bailiffs attend the debtor's premises to collect payment or seize goods. The workhorse option for judgments up to £5,000.
• Attachment of earnings. For individual debtors in employment — deductions taken directly from salary.
• Third-party debt order. Freezes and takes the money straight from the debtor's bank account, if you know where they bank.

Be honest with yourself about the limits here: enforcement is effective against debtors who have money and assets, and largely futile against those who don't. This is why the solvency check before filing matters so much.

Scotland and Northern Ireland

MCOL covers England and Wales only. In Scotland, the equivalent route is Simple Procedure in the sheriff court, for claims up to £5,000. In Northern Ireland, the Small Claims process in the county court covers claims up to £5,000 — but note it generally excludes debts arising from business contracts, so trade debts there usually go through the ordinary civil bill process. The statutory right to late payment interest and the fixed sum applies UK-wide either way.

A worked example

The better outcome: never needing court at all

Almost every invoice that ends up in court got there the same way: weeks of silence, then a flurry of panicked chasing, then escalation. The invoices that never reach this page are the ones chased early, consistently, and with the statutory charges applied from day one. That's exactly what Hielda automates — a full escalating chase sequence citing the Late Payment Act, daily interest calculated for you, the fixed sum applied, all sent on your behalf so you stay out of the awkwardness. Most debts resolve long before a Letter Before Action, let alone a claim form. But if a client does force the issue, you'll arrive at MCOL with a complete, timestamped paper trail — which is precisely what wins these cases.
