Understand what a breach of contract claim is, when you can make one in the UK small claims court, and how to build your case step by step.

Breach of contract claims

Contracts are at the heart of everyday life. Whether you’ve hired a tradesperson to renovate your kitchen, purchased goods from an online retailer, or paid a photographer to capture your wedding day, each of those arrangements is underpinned by a legally binding agreement. When one party fails to honour their side of that agreement, it can leave the other out of pocket, frustrated, and unsure of what to do next.

The good news is that English and Welsh law offers a straightforward route to recovering money lost through a broken contract — the small claims court. This guide explains what a breach of contract claim is, how to identify whether you have a valid one, what you can claim for, and how to get the process started.

What is a breach of contract?

A contract is formed when two or more parties reach an agreement, one party makes an offer and the other accepts it, and something of value (known as “consideration”) is exchanged — usually money in return for goods or services. Crucially, a contract does not have to be written down to be legally enforceable. Verbal agreements and informal email chains can all constitute valid contracts.

A breach occurs when one party fails to fulfil their obligations under that contract without a lawful excuse. Common examples include:

• A trader who takes payment but never completes the work
• A supplier who delivers goods that are faulty, incomplete, or not as described
• A service provider who delivers work significantly late, causing you financial loss
• A landlord who fails to carry out repairs they promised to undertake
• A business that cancels a booking at the last minute, leaving you with unrecoverable costs

Not every disappointment amounts to a breach. If a contract is genuinely ambiguous or the other party can show they met the agreed terms, your claim may be harder to pursue. It is worth reviewing the original agreement carefully before taking action.

Do you have a valid claim?

Before filing a claim, it helps to run through a simple checklist. To succeed in a breach of contract claim, you generally need to demonstrate four things:

1. A contract existed — There was a clear agreement, whether written, verbal, or implied by conduct.

2. The other party breached it — They failed to do what was agreed, or did something they were not supposed to do.

3. You suffered a loss — The breach caused you a quantifiable financial loss, not merely an inconvenience.

4. You acted promptly — In England and Wales, you normally have six years from the date of the breach to bring a claim. This is set out in the Limitation Act 1980.

If you can answer yes to all four points, you are likely in a strong position to proceed. Keep records of everything — contracts, invoices, receipts, messages, and any photographs of defective work — as these will form the backbone of your case.

How much can you claim in the small claims court?

The small claims track in England and Wales handles most straightforward contract disputes where the claim value is £10,000 or less. Claims above this threshold are generally allocated to a different track and may require legal representation, making them more costly and complex.

Your claim can include:

• The direct financial loss caused by the breach (for example, the amount you paid for work that was never completed)
• Consequential losses that flow naturally from the breach (for example, the cost of hiring someone else to fix a tradesperson’s poor workmanship)
• Statutory interest on the amount owed

Interest is an often-overlooked part of a claim. Under the County Courts Act 1984, the court can award interest at 8% per annum on money judgments. If you are unsure how much interest you may be entitled to add, use the ClaimsPilot interest calculator to work out an accurate figure before you file.

You cannot usually recover legal costs on the small claims track if you use a solicitor, so most people bring these claims themselves — which is exactly what the track is designed for.

Sending a letter before action

Before issuing a court claim, you are expected to follow the Pre-Action Protocol for Debt Claims or the general pre-action practice direction, depending on the nature of your dispute. In practice, this means sending the other party a formal letter before action (sometimes called a “letter before claim”).

This letter should:

• Clearly set out the nature of the breach
• State the amount you are claiming and how you have calculated it
• Give the other party a reasonable deadline to respond or pay (typically 14 days for most consumer disputes)
• Warn that you intend to issue court proceedings if the matter is not resolved

Sending a well-drafted letter before action serves two purposes. First, it gives the other party a final opportunity to settle the matter without the time and expense of court proceedings. Second, it demonstrates to the court that you attempted to resolve the dispute before escalating — judges take a dim view of parties who rush to litigation without first trying to negotiate.

You can generate a professional, properly formatted letter before action using the ClaimsPilot letter before action tool, which walks you through the process step by step.

Filing your claim

If the other party ignores your letter, denies the breach, or makes an offer you consider too low, you can proceed to issue a formal claim. In England and Wales, most small claims are filed online through Money Claim Online (MCOL), the government’s digital court service.

When completing your claim form, you will need to:

• Provide the full name and address of the defendant
• Write a concise particulars of claim explaining what happened, what was agreed, how the agreement was breached, and what loss you suffered
• State the total amount you are claiming, including any interest
• Pay the relevant court fee (fees are calculated on a sliding scale based on the claim amount and are listed on the GOV.UK court fees page)

Once issued, the defendant has 14 days to acknowledge the claim and 28 days to file a full defence. If they do not respond, you can apply for a default judgment. If they do defend, the court will usually list the matter for a short hearing.

Preparing for a hearing

Small claims hearings are deliberately informal. You do not need a barrister or solicitor. The judge will want to understand the key facts, see your evidence, and hear both sides. Arrive with a clearly organised bundle of documents — your contract or agreement, correspondence, invoices, photographs of any defective work, and a summary of your losses. Be ready to explain your case calmly and concisely.

What happens if you win?

Winning a judgment is one thing; collecting the money is another. If the defendant does not pay voluntarily, you will need to enforce the judgment. Options include:

• Warrant of control — County court bailiffs can seize and sell the defendant’s goods to satisfy the debt
• Attachment of earnings — Money is deducted directly from the defendant’s wages
• Third-party debt order — Funds can be taken directly from the defendant’s bank account
• Charging order — A charge is placed on the defendant’s property

Full guidance on enforcement options is available on GOV.UK. There are additional fees for most enforcement methods, though these can usually be added to the amount the defendant owes you.
