When a client will not pay and the polite emails have stopped working, a small claims unpaid invoice case is often the next realistic step. It is a formal court process, but ordinary business owners can use it without a solicitor. Thousands of sole traders and small limited companies do so every year to recover money that is rightfully theirs.
This guide explains how the small claims process for an unpaid invoice actually works in the UK in 2026: the limits in each nation, what you can claim for, what it costs to start, and what happens after you file. It also sets out the uncomfortable truth about what a judgment does and does not get you. The escalation steps that come before court, including the letter before action, are covered in a companion piece.
Small claims limits across the UK
The amount you can pursue through the small claims track depends on where you are. In England and Wales, the small claims limit is £10,000. In Scotland, the simple procedure (the Scottish equivalent) covers claims up to £5,000. In Northern Ireland, the small claims limit is £3,000. Above these thresholds, claims move into the fast track, intermediate track or multi-track procedures, where the costs rules change significantly and legal representation becomes far more common.
For most small business invoice disputes, the sums involved fall comfortably within these limits. That matters because all three systems are built around the same principle: you should be able to represent yourself without legal training, and you should not need to pay a solicitor more than the debt is worth.
A claim on a simple contract, which covers most unpaid invoices, can generally be brought within six years of the debt arising in England, Wales and Northern Ireland. In Scotland, the limit is five years. That gives you breathing room, but waiting rarely helps your cash flow or your evidence trail, so most advisers recommend acting well before the deadline approaches.
What belongs in your claim
A properly constructed claim is not just the invoice total. You are entitled to add statutory late payment interest if the debt falls under the Late Payment of Commercial Debts (Interest) Act 1998. You can also add a fixed compensation sum that scales with the invoice value: £40 for debts under £1,000, £70 for debts between £1,000 and £10,000, and £100 for debts of £10,000 or more. Together, the invoice amount, the interest and the fixed compensation form your total claim value, and that total determines which issue fee band you fall into.
Leaving interest and compensation off your claim form is one of the most common mistakes founders make. It understates what you are owed, and because the claim total sets the court fee, leaving them off rarely saves you money either. A separate guide explains how to calculate statutory interest correctly; the short version is that it applies automatically to qualifying business-to-business debts, and you should add it before you file.
One detail that regularly trips people up is the claimant’s name, which must match the contract exactly. Sole traders claim in their own name, adding their trading name if they use one. A limited company claims in its full registered name, because it is the company, not you personally, that is owed the money. If you are weighing up which structure your business should have, or want to check what yours means in situations like this, our guide to sole trader versus limited company status explains the practical differences.
Filing fees and the choice between Money Claim Online and form N1
Court issue fees for money claims in England and Wales are banded by claim value, and that value includes interest and compensation. As of 2026, the bands are:
- Up to £300: £35 fee
- £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
Claims between £10,000.01 and £200,000 pay a fee of 5 per cent of the claim value, and claims over £200,000 pay a flat fee of £10,000. Most invoice disputes sit well inside the lower bands.
Most small business claimants file through Money Claim Online. The digital service calculates your fee automatically based on the amount you enter. The alternative is the paper route, using form N1, sent to the Civil National Business Centre in Northampton, which handles postal claims centrally. Money Claim Online is faster, avoids postage delays and reduces the risk of errors in the fee calculation, which is why it has become the default route for most small business claims.
Crucially, if you win, the issue fee is recoverable from the defendant as part of the judgment. The court adds it to the amount the defendant must pay, so it is not a sunk cost if your claim succeeds.
What happens after you file
Once the court issues and serves your claim, the defendant has 14 days to respond. They have three real options. They can acknowledge the claim, which extends the response deadline to 28 days in total. They can admit the debt and propose a payment plan. Or they can defend the claim, in full or in part. How they respond shapes everything that follows.
If the defendant does nothing within the response window, you can apply for judgment by default, and the court enters judgment in your favour without a hearing because the other side failed to engage. If the defendant admits the debt, you get judgment by admission, often alongside an agreed instalment arrangement. Neither of these outcomes requires you to attend court.
If the defendant disputes the claim, it becomes a defended case and moves towards allocation and, eventually, a hearing. Before that happens, HM Courts and Tribunals Service (HMCTS) automatically refers defended small claims in England and Wales to free telephone mediation. This single call, usually under an hour, resolves a significant proportion of disputed cases. Neither party needs to attend a hearing, and it costs nothing extra to try.
One point worth understanding before you start: legal fees are generally not recoverable on the small claims track, even if you win. This is deliberate, and it is why the vast majority of small business claimants represent themselves. Paying for legal advice on a £2,000 invoice dispute rarely makes financial sense when you cannot recover those costs from the other side.
A judgment is an order, not the money
This is the part of the process that catches people out most often. Winning your case gives you a County Court Judgment (CCJ), a formal order stating that the defendant owes you the money. It does not give you the money. The court does not chase, collect or hold the debtor to account. That responsibility, and the further cost, sits with you.
Some defendants do pay promptly once judgment is entered, particularly because an unsatisfied CCJ damages their credit record for six years. If that happens, you are done. If they do not pay, you need to apply for enforcement separately, and that means paying another fee.
HMCTS sets the enforcement fees for England and Wales and publishes them in form EX50. The fees change periodically, so check the current version before you apply. As of 2026, the main fees are: an order to obtain information, £69; a warrant of control, £96; a High Court writ of control, £82; and an attachment of earnings order, third party debt order or charging order, £139 each. If six years or more have passed since the original judgment, you need the court’s permission first; that applies to both warrants of control and High Court writs.
An order to obtain information is often the sensible first step. It compels the debtor to attend court and disclose their financial position under oath, which tells you whether pursuing further enforcement is worth the additional outlay.
Choosing between bailiff and High Court enforcement
County Court bailiff warrants, using form N323, apply to debts under £5,000. High Court enforcement, using form N293A, is available once at least £600 is owed, and it becomes the required route for enforcing against goods where the judgment is £5,000 or more. High Court enforcement officers generally have stronger powers and a reputation for faster results, which is one reason some claimants transfer eligible judgments up to the High Court even when the County Court route would technically work.
Whichever route you choose, enforcement agents add their own fee stages to what the debtor owes. Under the Taking Control of Goods (Fees) Regulations 2014, as amended, these are £79 at the compliance stage, £247 at the enforcement stage and £116 at the sale stage, with a further 7.5 per cent on amounts above £1,900 at the enforcement and sale stages. In principle, these costs land on the debtor, not you. In practice, you only recover them if the debtor actually has something to recover from.
When enforcement is realistic, and which debts justify a claim
This is the question that matters most before you spend a single pound on fees: does the debtor have income or assets? A judgment against a dissolved company is, in blunt terms, a judgment you probably cannot enforce. The same goes for a debtor with no job and no property, or a business that has already gone into insolvency. The order to obtain information exists precisely to help you answer that question before you commit further money to warrants or High Court writs.
A practical rule many small business owners apply: pursue a small claims unpaid invoice case when three things are true. The sum is meaningful to your cash flow. The debtor is a trading business or an individual with a visible income or address. And you have clear paperwork: a signed contract, agreed terms, delivery proof and a paper trail of chasing attempts. Weak documentation is a warning sign. So is a debtor who has already disappeared, or a sum so small that the time cost outweighs the recovery. In those situations, the small claims process is not the right tool, however satisfying it might feel to file.
Because legal fees are not recoverable, the small claims system rewards founders who prepare their own case carefully, not those who assume a solicitor will do the heavy lifting. Keep your invoice, your contract terms, your correspondence and your interest calculation organised before you file. That preparation, not legal representation, is what tends to decide the outcome: a quick admission, a successful mediation, or a judgment you can actually collect.
