A Practical Guide to Restrictive Covenants in UK Employment and Commercial Agreements

Whether you’re hiring new staff for your growing business, negotiating with a crucial supplier, or planning a potential partnership, you may have come across the term restrictive covenants. But what are they-do you actually need them in your contracts? And just how enforceable are these “post-employment” or “non-compete” clauses in the UK?

Many small business owners, founders, and startups are keen to protect their client lists, intellectual property, confidential information and competitive edge as they grow. The right restrictive covenants can help-but if drafted incorrectly, they may be unenforceable (or even land you in legal hot water).

In this practical guide, we’ll break down what restrictive covenants are, how they work in UK law, which ones matter most in employment and commercial settings, and what’s involved in making sure they’re legally binding. We’ll also walk through tips for business owners, common pitfalls, and when it’s vital to get professional help. If you want your contracts to offer real protection-without tripping up on UK employment law-keep reading.

What Are Restrictive Covenants?

Restrictive covenants are clauses in contracts-usually found in employment agreements, shareholder agreements, or commercial deals-that place limits on what an individual or business can do both during and after a relationship ends. The main goal? To protect your legitimate business interests, such as:

• Preventing ex-employees from joining a rival or soliciting your clients
• Safeguarding confidential information and trade secrets
• Stopping partners or former associates from setting up in direct competition

In other words, restrictive covenants help ensure your business isn’t left vulnerable if a key person leaves or a deal goes sour.

Why Are Restrictive Covenants Important for UK Businesses?

Running a small business, you’ve likely invested significant time and money developing relationships, trade secrets, and valuable know-how. If an ex-employee or business partner can walk out and “take it all with them,” you risk losing your competitive edge (and sometimes your best clients) overnight.

Restrictive covenants are your first line of defence. They work alongside other contracts-like employment contracts and shareholder agreements-to give you a fighting chance of protecting what makes your business unique.

However, UK law won’t let you use these clauses just to stop someone from fair competition. The courts only enforce restrictive covenants if they’re:

• Reasonably necessary to protect your legitimate business interests
• Not broader than absolutely needed (in scope, time, or geography)
• Clear, specific and not against public policy

What Types of Restrictive Covenants Are Common in the UK?

In the UK business world, there are four main types of restrictive covenants you’ll see in employment and commercial agreements:

1. Non-Compete Clauses - Ban someone (usually an ex-employee or exiting shareholder) from working for a direct competitor or starting a competing business for a set time and in a set area.
2. Non-Solicitation Clauses - Prevent a departing individual from approaching your business’ clients, customers, or suppliers for their own benefit.
3. Non-Dealing Clauses - Go one step further than non-solicitation, blocking any dealings (whether approached or not) with your key customers or contacts.
4. Non-Poaching (or Non-Enticement) Clauses - Stop former staff or partners from poaching your current employees or team for a rival operation.

You might also find confidentiality clauses (sometimes called non-disclosure agreements, or NDAs) in your contracts, but these are a broader topic. You can read more in our guide to confidentiality contracts and NDAs in business.

Do Restrictive Covenants Apply Only to Employees?

No-restrictive covenants are used in more than just employment contracts.

They’re common in:

• Shareholder Agreements - To keep founders or major investors from setting up a rival after leaving.
• Franchise Agreements - To stop ex-franchisees from starting a competing business in a certain area.
• Commercial Contracts & Supplier Agreements - For example, making sure your manufacturer doesn’t sell your product design to every other client.
• Consultancy or Contractor Agreements - To prevent a departing consultant from poaching your clients or staff.

Regardless of the relationship, the core principles around enforceability (reasonableness, protecting a legitimate interest, clear drafting) always apply.

Are Restrictive Covenants Enforceable in the UK?

This is the million-pound question! UK courts approach restrictive covenants with caution. They’re considered a “restraint of trade”, so the court will only uphold them if the business can show:

• The restriction is reasonable-it must go no further than necessary to protect your business (for example, 12 months for a non-compete is much harder to enforce than 3-6 months).
• It’s clearly drafted-no vague or broad clauses, and all terms (like what counts as “competition”) are defined.
• It protects a genuine business interest (not just to stop fair competition for its own sake).

If a court finds the clause too broad-or that it’s just there to stop someone finding work-they may strike out the covenant altogether. That’s why it’s vital to get these clauses tailored to your business’ needs, rather than copying what another company uses!

Common Mistakes That Make Restrictive Covenants Unenforceable

Most disputes over restrictive covenants happen because the clause is:

• Unclear or “catch-all” in scope (e.g., bans on “any work in a similar sector”)
• Excessively long in duration or broad in geographic reach
• Trying to protect more than a legitimate interest justifies
• Tacked on from a template, without thinking through your business’ real risks

What Should Restrictive Covenants Cover in Your Agreements?

To ensure your restrictive covenants work, they must:

• Specify exactly what activities are restricted (and what counts as “competition”)
• Clearly define who is covered (e.g., the employee, franchisee, contractor)
• Set firm, reasonable time limits (typically 3, 6 or 12 months, depending on the type of restriction and role)
• Where relevant, define the geographic area (a national or global ban rarely holds up-local or regional is more likely to be enforceable)
• Tie the restriction to a legitimate interest (client relationships, confidential info, trade secrets, etc.)

It’s a good idea to revisit your restrictive covenants regularly, especially if your business model or operations change.

Step-By-Step: How Do I Add Restrictive Covenants to My Contracts?

Ready to get serious about contract protection? Here’s a practical workflow for business owners and managers:

1. Assess Your Real Business Risks
   • Consider which secrets, relationships or investments need protection (think client lists, pricing strategies, unique processes, etc.)
   • Ask yourself: If this person left and worked for a competitor next week, what damage could they do?
2. Choose the Right Restrictive Covenants
   • Pick the most relevant types-non-compete, non-solicitation, non-dealing, non-poaching or some combination
3. Define Terms Clearly
   • Spell out who/what/where/when for each restriction
4. Make Duration and Geography Reasonable
   • Shorter, targeted restrictions are more likely to be enforced than all-encompassing bans
   • Consult our guide to restrictive covenants in employment contracts for real-world examples
5. Review Regularly-and Get Expert Help
   • Laws and market norms change. Have a solicitor check your contracts each year, or if your business evolves
   • Avoid DIY drafting with templates-use a professional who understands your unique situation and UK case law

What UK Laws Affect Restrictive Covenants?

Several core laws and legal principles shape how restrictive covenants work in the UK:

• Common Law “Restraint of Trade” Doctrine - The courts will only enforce a restriction if it’s reasonable and goes no further than necessary.
• Employment Rights Act 1996 & Equality Act 2010 - Covenants can’t be used to disadvantage employees unlawfully (such as denying their right to work post-termination).
• Trade Secrets (Enforcement, etc.) Regulations 2018 - These set out additional protection for confidential business information, but don’t replace the need for contractual terms.
• Competition Law & Consumer Protection Law - Overly broad restrictions can trigger competition issues or be ruled as unfair contract terms (especially in B2B deals or franchise agreements).

Each situation is unique-if you’re unsure about the legal framework for your industry or type of contract, it’s wise to talk to a contract lawyer.

What Happens If Someone Breaches a Restrictive Covenant?

If a former employee, partner or franchisee breaches a restrictive covenant, you generally have a few options:

• Seek an injunction - A court order to force them to stop the prohibited activity (often the most urgent remedy)
• Claim damages - Financial compensation for any loss you can prove was caused by the breach
• Negotiate a settlement - Sometimes a carefully-worded “letter before action” will prompt the other side to honour the restriction

Litigation is always a last resort. The best defence is a clear, well-drafted agreement-one that’s more likely to hold up if you ever need to enforce it. For more on resolving disputes, see our guide to breach of contract in the UK.

How Do Restrictive Covenants Interact With Confidentiality Clauses?

Restrictive covenants and confidentiality clauses work hand-in-hand. While restrictive covenants stop certain activities (like working for a rival), confidentiality clauses make it clear that sensitive information must remain secret during and after employment or a business partnership.

Even if an ex-employee is allowed to work for a competitor, they cannot disclose (or use) trade secrets or inside knowledge protected by a confidentiality agreement. It’s smart to include both kinds of protection, and there’s no such thing as having “too much” clarity when it comes to safeguarding your IP and business processes.

When Should I Seek Legal Help With Restrictive Covenants?

If you’re unsure about any of the following, professional advice is a must:

• You’re drafting new employment or commercial contracts
• You want to review or update existing restrictive covenants
• Someone has breached a clause (“can I actually enforce this?”)
• Your business is entering a merger, acquisition or franchising scenario (where multiple parties’ covenants need aligning)

Getting legal advice early means you won’t waste time (or money) on terms that are likely unenforceable. And you’ll sleep better knowing your business isn’t exposed to unfair competition risks.

Key Takeaways

• Restrictive covenants are powerful contract tools for protecting your business, but only work if they’re tailored, reasonable, and clear.
• UK law will not enforce overly broad or vague restrictions-each clause must protect a specific legitimate interest and go no further than needed.
• Common covenants include non-compete, non-solicitation, non-dealing, and non-poaching clauses, in both employment and commercial contracts.
• Always review restrictive covenants regularly and seek expert legal advice before adding, updating, or enforcing these terms in the UK.
• Confidentiality clauses and restrictive covenants are strongest when they work together-don’t rely on one without the other.
