Running a business in the UK means dealing with people, contracts, money, and expectations, and sooner or later something goes wrong. A supplier misses a deadline, a customer refuses to pay, a former employee walks out with your client list, or a co-director makes decisions you never agreed to.

When that happens, what started as a working relationship can quickly turn into a commercial dispute with real consequences for your cash flow, your reputation, and your time. I'm Brad Askew, and I've spent years working at the intersection of law and technology helping business owners get clarity when things get messy.

This guide walks through the most common types of commercial disputes I see in the UK, how they tend to unfold, and the practical steps that can help you protect your position before matters escalate.

Overview

A business or commercial dispute is any disagreement that arises between parties in a commercial context where one side believes the other has failed to honour an obligation, acted unfairly, or caused loss. These disputes can involve two companies, a company and its customers or suppliers, shareholders arguing among themselves, directors accused of acting outside their authority, or partners falling out over the running of a firm.

In the UK, commercial disputes are generally governed by a mix of contract law, company law under the Companies Act 2006, partnership law, tort, and intellectual property statutes, with procedure handled through the Civil Procedure Rules. Most disputes never reach a courtroom.

The majority are settled through direct negotiation, letters before action, mediation, or arbitration, which is usually faster and cheaper than litigation. Knowing what type of dispute you're dealing with, and what remedies are realistically available, is the first step toward a sensible outcome.

That might mean recovering money owed, enforcing a contract, protecting confidential information, or simply drawing a line and moving on.

Key steps

Work out exactly what you're disputing. Before you fire off letters or call a lawyer, get clear on the facts. Write down what was agreed, what actually happened, who said what and when, and what loss you've suffered. Gather emails, contracts, invoices, meeting notes, and any messages that support your version of events. A tidy paper trail is worth more than a strong opinion.

Check the contract and any governing terms. Most commercial disputes turn on what the paperwork actually says, not what either side remembers. Look for clauses covering termination, payment terms, notice periods, limitation of liability, dispute resolution, and governing law. If there's a mandatory mediation or arbitration clause, you'll usually need to follow it before going to court, so read the small print carefully.

Open a direct conversation before escalating. Many disputes escalate because nobody picked up the phone early enough. A calm, documented conversation with the other party, ideally followed up in writing, can resolve misunderstandings without legal costs. Be specific about what you want: payment by a certain date, delivery of outstanding work, or a written apology and correction. Keep emotion out of it.

Send a formal letter before action if needed. If informal contact fails, the next step is usually a letter before action setting out the claim, the facts, the legal basis, what you want, and a deadline for response. Under the Civil Procedure Rules, pre-action conduct matters, and courts can penalise parties who skip this stage. A well-drafted letter often produces a settlement on its own.

Consider mediation, arbitration, or court. If the dispute still isn't resolved, think about which forum fits best. Mediation is confidential and non-binding, and useful when both sides want to preserve a relationship. Arbitration produces a binding decision in private. Court litigation is public and more formal, but sometimes necessary, particularly where urgent injunctions or significant sums are at stake.

Common questions

QWhat counts as a breach of contract in the UK?

A breach of contract happens when one party fails to do what they agreed to do under a legally binding agreement, or does it badly or late. It can be a missed payment, undelivered goods, substandard work, or a broken promise about exclusivity or confidentiality. Not every breach justifies ending the contract. Minor breaches usually entitle you to damages, while serious or repudiatory breaches can allow you to terminate and claim losses.

QHow long do I have to bring a commercial claim?

For most contract claims in England and Wales, the Limitation Act 1980 gives you six years from the date of breach to issue proceedings, extended to twelve years if the contract was executed as a deed. Tort claims, including some intellectual property matters, have their own time limits. Miss the limitation deadline and your claim is usually barred, so it's worth acting well before the clock runs out.

QCan directors be personally liable in a dispute?

Yes, in certain situations. Directors owe statutory duties under the Companies Act 2006, including duties to act within their powers, promote the success of the company, and avoid conflicts of interest. Breaching those duties can lead to personal claims by the company or, in insolvency, by a liquidator. Directors can also face personal liability for wrongful trading, fraudulent trading, or giving personal guarantees.

QWhat is unfair competition and is it illegal in the UK?

The UK doesn't have a single standalone law of unfair competition, unlike some European countries. Instead, unethical commercial behaviour is dealt with through a patchwork of rules covering passing off, trade mark infringement, breach of confidence, misleading advertising, and the Consumer Protection from Unfair Trading Regulations. Whether something is actionable depends on the specific conduct, so the label matters less than identifying which legal route applies.

QShould I mediate or go straight to court?

Mediation is usually worth trying first. It's faster, cheaper, confidential, and often preserves the commercial relationship. Courts actively encourage mediation and can penalise a party that refuses it unreasonably by adjusting costs orders. That said, mediation isn't right for every case, particularly where urgent relief is needed, the other side is acting in bad faith, or a binding precedent is required.

QWhat happens if someone infringes my intellectual property?

If another business uses your trade mark, copyright, patent, or design without permission, you may have grounds for a claim. Remedies can include an injunction to stop the infringement, damages or an account of profits, delivery up of infringing goods, and legal costs. The first practical step is usually a cease and desist letter setting out your rights and giving the other side a chance to back down before litigation.

QHow much does it cost to resolve a commercial dispute?

Costs vary enormously depending on complexity, value, and how quickly matters settle. A dispute resolved by correspondence may cost very little, while a fully contested High Court case can run into substantial legal fees. Court fees themselves depend on the value of the claim, so check gov.uk for the current amount. Most disputes are resolved long before trial, which keeps costs far lower than most people expect.

If this matter is likely to be contested or escalates beyond general guidance, you may want proper representation. Find a civil disputes solicitor.
