Understanding Breach of Restrictive Covenants: What UK Businesses Need to Know

When you’re running a business in the UK, there’s a lot to juggle. From building a talented team to launching innovative products, every decision can play a big role in your success (or potential setbacks). One area that often gets overlooked by small business owners is managing how confidential information, customer relationships, or trade secrets are protected - especially when key employees or business partners decide to move on.

If you’ve ever wondered how restrictive covenants work in the UK, or what actually happens if someone breaches one, you’re in the right place. Understanding these contract clauses-and what to do when a breach occurs-can mean the difference between safeguarding your business or facing frustrating disputes down the line. We’ll break down what you need to know, what to watch for, and how to be ready with the right legal foundations from day one.

Keep reading to get clear answers on practical steps, UK laws, and what to do if you suspect a breach.

What Is a Restrictive Covenant?

Let’s start at the basics. A restrictive covenant is a contract clause that limits a person’s actions during (and often after) their time with your business. You’ll often see them used in employment contracts, partnership agreements, and even business sale deals. Their main purpose? Protecting your business’s sensitive information, customer and supplier relationships, and competitive advantage after someone with insider knowledge leaves.

Common types of restrictive covenants include:

• Non-compete clauses - prevent an employee or former business partner from setting up in direct competition or joining a rival for a specific period and area after they leave.
• Non-solicitation clauses - stop someone from approaching your customers, clients, or employees after they move on.
• Non-poaching clauses - prevent ex-employees or partners from tempting your staff away.
• Non-dealing clauses - stop someone from doing business with your customers or contacts, even if the customer approached them first.

These are all about preserving your business’s hard-won assets and relationships-so it’s crucial to get them right and know what happens if they’re ignored.

When Do Restrictive Covenants Apply in UK Business?

Restrictive covenants aren’t just for big corporations. Most UK businesses-no matter the size-use these clauses somewhere. Here’s where you’re likely to see them come up:

• Employment contracts (especially for senior or specialist roles)
• Shareholders’ agreements and partnership deeds
• Business sale agreements (protecting the buyer if the seller stays in the industry)
• Franchise agreements

For example, when selling a business, the buyer will almost always insist that you don’t set up in direct competition or poach customers or staff for a period after the sale. If you’re employing top talent or contractors, it’s also common to include tailored restrictive covenants-to keep your intellectual property, trade secrets, or customer lists secure.

If you’re unsure how these clauses apply to your situation, it’s a smart move to get expert legal advice on your contracts before taking the next step.

Are Restrictive Covenants Legally Enforceable in the UK?

This is where things get a bit more technical. In the UK, restrictive covenants are enforceable only if they are:

• Reasonable - The restriction must go no further than needed to protect your legitimate business interests.
• Clear and specific - Vague or overly broad covenants are likely to be struck out by a court.
• Limited in time, geography, and activity - The shorter the restriction and the more tailored to your business, the better chance it will stand up.

UK courts take a balanced approach-they don’t want to unfairly prevent someone from earning a living, but they do recognise a business’s right to protect itself. If the covenant does nothing more than protect genuine interests (like confidential data or unique client relationships), and is proportionate, it’s likely to be enforceable.

On the flip side, if a restrictive covenant tries to stop someone working anywhere in the UK for two years after leaving your business, it will almost certainly be struck down.

What Counts as a Breach of Restrictive Covenant?

A “breach” simply means the individual has done something the covenant clearly prohibits. Some classic breach scenarios might look like:

• A former employee starts a rival business or joins a competitor during the period of the restriction
• They approach (or “poach”) your existing customers, clients, or team members despite an agreement not to
• The ex-employee uses confidential information, trade secrets, or supplier lists gained from your business in their new venture

The breach doesn’t have to be deliberate-even accidental or indirect action can lead to legal issues if it falls foul of your contract.

If your business is dealing with a potential breach, knowing what steps to take next is crucial for protecting your interests. For a deeper breakdown on contract disputes and what to do, our guide to breach of contract in the UK is a great resource.

How Can You Spot a Breach - And What Should You Do?

Catching a breach early often means less disruption and a better chance of a swift resolution. Here’s what to look out for:

• Noticing ex-employees on competitor websites, LinkedIn, or trade directories
• Clients suddenly leaving or mentioning contact from a former staff member
• Leaked confidential info, or similarities between your operations and a competitor’s new launch soon after someone leaves
• A sudden jump in staff turnover, especially if high performers are joining a specific competitor

If you’ve spotted something concerning, here are some practical first steps:

1. Review the contract: Double-check the exact terms of the restrictive covenant and how it applies to the situation. Look for timeframes, geographical reach, and which activities are off-limits.
2. Gather evidence: Document any communications, client migrations, or new business activities that suggest a breach. Evidence could include emails, screenshots, LinkedIn pages, or witness statements.
3. Seek legal advice: Before reaching out to the individual or a competitor directly, consulting a solicitor experienced in contract disputes will clarify your position and next steps. They’ll help you weigh up your rights and propose a strategy.
4. Consider resolution options: These range from a formal “cease and desist” letter to seeking an injunction to stop the breach, or even a claim for damages if your business has lost money as a direct result.

It’s important not to delay action-speed can be critical, especially if you need to seek a court injunction or stop the spread of sensitive information. Acting in a calm, informed, and legally sound way will get the best results.

What Legal Remedies Are Available for a Breach of Restrictive Covenant?

If the breach of a restrictive covenant is proven, you may be able to pursue several remedies:

• Injunctions: These are urgent court orders preventing further breach. For example, stopping a former staff member from working for a competitor during the restricted period or from using confidential information.
• Damages: Compensation for any financial loss your business suffered as a direct result of the breach (such as lost revenue, stolen clients, or poached staff).
• Account of profits: In rare cases, if your competitor profited by using your trade secrets or client lists, you might claim a share of those profits.

Bear in mind that courts only grant these remedies if your covenant is enforceable (see above), and the breach can be clearly shown. This makes it essential to:

• Have well-drafted, up-to-date contracts that match current UK legal standards
• Clearly document restrictions-length, area, specific protected interests
• Keep a paper trail of employment, resignation, and exit communications

How Do You Make Restrictive Covenants Strong - and Fair?

The best approach to restrictive covenants is to focus on being both robust and reasonable. UK tribunals don’t look kindly on excessively broad or generic clauses. In practice, you should aim to:

• Limit the restriction to what’s genuinely needed (e.g., 6-12 months for most non-compete or non-solicitation clauses is the market norm-rarely longer)
• Define the relevant geographical area (e.g., specific city, client region, or area where your business operates)
• Be clear about what information, relationships, or assets you’re aiming to protect
• Tailor clauses to the role-senior execs may require stricter terms than junior team members
• Review covenants regularly as your business grows and changes

Not sure what’s appropriate for your business or sector? Sprintlaw can help draft or review your employment contracts, partnership agreements, or confidentiality and non-disclosure agreements (NDAs) to ensure maximum protection-without overstepping UK employment law.

What Happens if Restrictive Covenants Are Unenforceable?

If your restrictive covenant is found to be unreasonable or poorly drafted, a UK court may:

• Strike down the entire clause - making it as if it never existed
• Refuse to enforce it - meaning the individual is free to compete, solicit, or use information
• Refuse your claim for damages - leaving your business out of pocket and exposed

This is why it’s so important to have covenants reviewed, updated, and tailored to your unique business needs-especially before signing a new employee or business sale.

What Key UK Laws Affect Restrictive Covenants?

When dealing with restrictive covenants and their potential breach, some of the main UK legal frameworks include:

• Employment Law - Protects worker rights and limits how far employers can restrict employees’ future work. Tribunals often step in if a clause is too harsh.
• Contract Law - Sees restrictive covenants as only enforceable if they protect legitimate business interests and are proportionate.
• Restraint of Trade Doctrine - UK common law, which presumes that any restriction on trade is void unless justified as reasonable.
• Data Protection - If a breach exposes confidential or personal data, rules under the Data Protection Act 2018 and UK GDPR may also apply.

Because the law around enforcement is complex, getting the right legal guidance from the start (and with each new deal) can make all the difference.

How Can You Avoid Breach of Restrictive Covenant Disputes?

Prevention is nearly always easier and cheaper than the cure. Here’s how to set your business up for minimal risk:

• Use professional contract drafters - avoid internet templates or DIY clauses that might not stand up in court.
• Clearly explain the terms to staff or business partners before they sign-transparency helps future compliance.
• Keep employment and exit interviews documented-including reminders about any ongoing obligations.
• Monitor for breaches-but avoid overreaching or “spying.” Only act on clear, evidence-based concerns.
• Keep contracts up to date-review and refresh regularly as roles or the business change.

If a disagreement still pops up, addressing it quickly and with well-structured legal advice will help prevent escalation.
