Struggling with unpaid freelance invoices? Learn how UK freelancers can recover overdue payments, from chasing clients to using the small claims court.

Freelancer payment disputes: how to recover what you’re owed

Freelancing offers flexibility and freedom, but it comes with a significant financial risk: clients who don’t pay. Whether you’re a graphic designer waiting on a final invoice, a copywriter chasing a late fee, or a developer owed thousands for a completed project, unpaid work is one of the most frustrating challenges freelancers face in the UK.

The good news is that you have legal rights. UK law gives freelancers clear routes to recover money owed for goods or services, including through the small claims court — a process that doesn’t require a solicitor and can be handled largely online. This guide walks you through your options, step by step.

Understanding your legal position as a freelancer

When a client commissions your services and you complete the work agreed, a contract exists — even if it was never written down. A series of emails, a verbal agreement, or even a WhatsApp exchange can all constitute a legally binding contract. What matters is that there was an offer, acceptance, and agreed consideration (i.e., payment).

This means that if a client refuses to pay after you’ve delivered the work, they are likely in breach of contract. You have the right to pursue that debt through the civil courts, including the small claims track, which handles disputes up to £10,000 in England and Wales (£5,000 in Scotland and £3,000 in Northern Ireland).

Before taking any formal steps, it helps to gather your evidence. This includes:

• Signed contracts or written agreements
• Emails or messages confirming the scope and fee
• Invoices you’ve sent
• Any delivery confirmations or sign-offs from the client
• Records of chasing payment

The stronger your paper trail, the more confident you can be in pursuing a claim.

Chasing payment: what to do before escalating

It might sound obvious, but the first step is to make sure you’ve given the client a reasonable opportunity to pay. Payment terms matter here — if your invoice states 30 days, the clock starts from when the invoice was received, not when the work was completed.

If payment hasn’t arrived by the due date, try the following:

1. Send a polite reminder — sometimes invoices genuinely get lost or overlooked, especially in larger organisations.

2. Follow up by phone or email — direct communication can resolve things faster than waiting.

3. Clarify any disputes — if the client says there’s an issue with the work, address it in writing so you have a record.

If you’re a business-to-business (B2B) freelancer invoicing another business, you’re also entitled to claim statutory interest under the Late Payment of Commercial Debts (Interest) Act 1998. This allows you to charge 8% above the Bank of England base rate on overdue invoices, plus a fixed compensation fee depending on the debt size.

To work out exactly how much statutory interest you’re owed, use the ClaimsPilot interest calculator — it does the maths for you based on the debt amount and how long it’s been overdue.

Sending a letter before action

If chasing informally hasn’t worked, the next step is to send a formal letter before action (also called a letter before claim). This is a written notice that tells the client:

• How much you’re claiming
• Why you believe they owe you the money
• That you intend to take legal action if they don’t pay within a set timeframe (typically 14 days)

Sending a letter before action is not just good practice — it’s actually required before you can file a claim in the small claims court. Courts expect both parties to have tried to resolve the dispute before litigation, and skipping this step could count against you.

A well-written letter before action often prompts payment without you ever needing to go to court. Many clients, particularly businesses, don’t want the hassle or reputational damage of a court claim and will settle once they realise you’re serious.

You can create a professional, court-ready letter before action using the ClaimsPilot letter before action tool. It guides you through the key details and produces a letter formatted to the expectations of the Pre-Action Protocol for Debt Claims.

What happens if the client still doesn’t pay?

If the deadline in your letter before action passes without payment or a reasonable response, you can proceed to file a claim with the court. In England and Wales, this is done through the Money Claim Online (MCOL) service, run by HM Courts & Tribunals Service.

The process works broadly like this:

1. File your claim — you’ll provide details of the debt, your evidence, and pay a court fee (which can be added to the amount you’re claiming if you win).

2. The defendant is served — the court notifies the client, who has 14 days to respond.

3. If they don’t respond — you can apply for a default judgment, which is a formal court order requiring them to pay.

4. If they dispute the claim — the case is allocated to the small claims track for a hearing, usually informal and conducted by a district judge.

Court fees for small claims are relatively modest. For example, a claim for £1,000 costs £70 to file, while a £5,000 claim costs £205. You can find the full fee schedule on GOV.UK.

It’s worth noting that winning a judgment doesn’t automatically mean you’ll receive the money. If a client refuses to pay even after a court order, you may need to take enforcement action — such as instructing a High Court enforcement officer or applying for an attachment of earnings. The GOV.UK guidance on enforcing a judgment explains your options in detail.

Common pitfalls freelancers should avoid

Pursuing a payment dispute can feel stressful, especially when you’re doing it alone. Here are some common mistakes to watch out for:

Not having anything in writing. Verbal agreements can be legally valid, but they’re much harder to prove. Always follow up verbal discussions with a written summary — even a quick email saying “just to confirm, we’ve agreed X for Y fee” can be enough.
Waiting too long. In England and Wales, you have six years from the date a debt became due to bring a claim (this is the limitation period under the Limitation Act 1980). Waiting too long doesn’t just reduce your chances of recovering payment — it can also make your evidence harder to piece together.
Accepting part payment without written caveats. If a client offers to pay a reduced amount “in full and final settlement,” accepting it without objecting in writing could prevent you from claiming the remainder later. If you accept a partial payment but intend to pursue the balance, state this clearly in writing at the time.
Not accounting for disputed work. If there’s a genuine dispute about whether the work met the brief, you may need to show evidence that you delivered what was agreed — which is why keeping client sign-offs and approval emails is so important.

Protecting yourself from future disputes

While this guide focuses on recovering money you’re already owed, it’s worth briefly considering how to protect yourself going forward.

• Always use a written contract. Even a simple one-page agreement covering scope, fee, payment terms, and what happens if there’s a dispute can save a great deal of trouble later. HMRC has guidance for the self-employed that touches on the importance of clear working arrangements.
• Invoice promptly and clearly. Include your payment terms, bank details, and a unique invoice number on every invoice.
• Consider asking for a deposit. Particularly for new clients or large projects, asking for 25–50% upfront reduces your exposure if things go wrong.
• Keep records of everything. Emails, messages, files, delivery confirmations — all of it could matter if a dispute arises.
