Understanding Non-Solicitation Clauses in UK Business Contracts: A Guide for Employers and Entrepreneurs

If you’re running a business, you’ve probably heard of “non-solicitation clauses”-but what do they actually mean for your contracts, team, and long-term business success?

Whether you’re hiring new staff, bringing in freelancers, or growing your client base, these clauses can be key to protecting your business from losing clients, employees, and valuable business connections. But non-solicitation clauses also come with specific risks and rules in the UK, so it’s essential to get them right from day one.

This guide will break down what a non-solicitation clause is, why it matters, how to use them lawfully, and steps you can take to ensure your business is fully protected-without overstepping legal boundaries. Ready to demystify non-solicitation clauses? Let’s get started.

What Is a Non-Solicitation Clause?

A non-solicitation clause is a contractual promise that limits one party-usually an employee, contractor, or business partner-from “poaching” or actively seeking out your clients, customers, or staff, typically after they leave your business or after your contract ends.

In plain English, it means that if someone stops working with you, they can’t immediately try to take your clients with them or encourage your own team to leave and join a competitor. This can offer valuable peace of mind-especially in competitive industries where relationships hold a lot of value.

A typical non-solicitation clause might appear in:

• Employment contracts
• Contractor agreements
• Shareholders’ agreements
• Partnership agreements
• Business sale or purchase contracts

It’s not unusual for non-solicitation clauses to appear alongside restraint of trade clauses (like non-competes), which stop someone from working for a rival, or confidentiality agreements, which prevent the use of sensitive information.

Why Do Businesses Use Non-Solicitation Clauses?

Let’s put ourselves in the shoes of a business owner who’s just spent months or years building relationships with clients, investing in employee development, and creating an edge over the competition.

Now, imagine a key employee leaves-and instantly starts contacting your top clients, enticing them to move to their new employer. Or, they start calling up their old teammates, encouraging them to jump ship. Suddenly, your business’s hard-earned list of contacts (and future profits) could evaporate overnight.

This is exactly why businesses use non-solicitation clauses. They give you:

• Confidence that former staff or partners can’t immediately solicit your clients or employees
• Time to reinforce relationships or replace key staff if someone leaves
• Legal grounds to act if someone tries to ‘poach’ clients or employees in breach of contract

Ultimately, non-solicitation clauses underpin your business’s resilience-especially as you grow, diversify, or operate in industries where relationships and contacts are everything.

How Does a Non-Solicitation Clause Work in Practice?

Non-solicitation clauses typically work by stating (in writing) that one party agrees not to:

• Approach, contact, or attempt to “poach” (solicit) your clients, suppliers, or customers
• Encourage or entice your employees to leave and join another business

This applies for a specific time period (for example, 6-12 months) and usually within a particular geographical area or business context. For instance:

• A former sales manager cannot contact your clients and offer them competing services within 12 months of leaving your company
• A contractor cannot approach your team members and ask them to work on a new project for a rival company immediately after your contract ends

The most effective non-solicitation clauses are crystal clear-setting out:

• Who is covered (e.g. employees, contractors, partners)
• Which contacts are included (e.g. current clients, recent customers, team members)
• What counts as “solicitation” (direct contact, indirect approaches, etc.)
• The length of the restriction (commonly 3-12 months)
• Geographical or business scope (which markets or locations?)

If someone breaks a non-solicitation clause, you may have grounds to take action, including seeking an injunction (a court order to stop the unlawful behaviour) or claiming compensation for any losses caused.

Are Non-Solicitation Clauses Enforceable in the UK?

It’s a great question-and an important one. In the UK, non-solicitation clauses can be enforceable, but you need to walk a fine line. Courts will only uphold these clauses if they go no further than reasonably necessary to protect your “legitimate business interests.”

That means:

• You must be protecting something real-like confidential relationships or trade secrets, not just preventing normal competition
• The clause must be limited in time, scope, and geography-it can’t be excessively broad (for example, a 5-year worldwide ban will almost always be struck down)
• The restriction shouldn’t unfairly stop someone earning a living

Cleverly drafted non-solicitation clauses offer targeted protection while staying legally robust. Overly broad or vague clauses risk being thrown out by a judge, leaving your business exposed.

What Is the Difference Between Non-Solicitation and Non-Compete Clauses?

This is a common point of confusion. Here’s how they differ:

• Non-Solicitation: Prevents a departing employee, contractor, or partner from directly approaching or enticing your clients, customers, or staff. It doesn’t always stop them from working for a competitor, only from “poaching.”
• Non-Compete: Bans a former staff member or partner from working for (or starting) a rival business within a set timeframe or area. Non-compete clauses are harder to enforce in the UK and must be tightly drafted to avoid being void as a “restraint of trade.”

Many contracts include both types of clauses, but each should be treated separately, with careful wording and legal review. If you only want to stop client or staff “poaching,” a well-drafted non-solicitation clause is often enough.

When Should You Use a Non-Solicitation Clause?

Non-solicitation clauses aren’t just for large corporations-they’re a smart move for any business that:

• Relies on repeat or high-value clients
• Invests significant time or money training employees
• Operates in a specialised industry or niche market
• Collaborates with contractors, freelancers, or external sales agents
• Is selling, merging with, or acquiring another business and wants to protect key relationships

If that describes your business, it’s wise to include a non-solicitation clause in your core contracts and agreements from the outset. You may also want to review your existing contractor agreements and employment contracts to ensure these protections are in place and up-to-date.

What Should a Non-Solicitation Clause Include?

The best non-solicitation clauses are tailored to your business model and clearly set out:

• Who is covered: e.g. employees, ex-employees, contractors, partners, consultants
• Who you want to protect: e.g. current clients, former clients, staff, suppliers
• Definition of solicitation: e.g. direct or indirect approaches (including via LinkedIn or social media), encouraging to leave, assisting a competitor to make contact
• Timeframe: Commonly 3-12 months, depending on the business risk and the seniority of the person involved
• Geographical scope: If relevant, state whether it applies to the UK, Europe, or other areas
• Remedies for breach: For example, “injunctive relief” (a court order) and/or damages

Careful drafting is crucial. Vague or excessive restrictions are likely unenforceable. For professional help creating bulletproof clauses, our team can draft and review your contracts to ensure they stand up in court.

What Happens If Someone Breaches a Non-Solicitation Clause?

If you think a former team member or partner is breaching a non-solicitation clause (for example, you notice clients are leaving immediately after someone has left your business), it’s important to act quickly:

1. Gather Evidence: Compile communications, emails, LinkedIn messages, or any direct approach to your clients or staff.
2. Review the Clause: Check that it’s clear, reasonable, and applies to the behaviour in question. Not all clauses are enforceable, so it’s best to seek legal guidance.
3. Send a Warning Letter: You may start by sending a formal letter demanding the other party cease all solicitations and reminding them of their contract obligations.
4. Legal Action: If the behaviour continues, you may be able to apply for a court injunction and claim for any losses. For high-stakes cases, this is best done with a legal professional by your side. Learn more about responding to breaches of contract here.

Taking early and decisive action is often enough to resolve the problem without costly litigation-but the stronger and more specific your original clause, the better your leverage and outcome.

How Can You Make Sure Your Non-Solicitation Clause Is Enforceable?

Courts in the UK are wary of overly strict or vague clauses that do more than protect your genuine interests. To maximise your chances of enforceability:

• Be specific about the relationships or information you’re trying to protect
• Limit the restriction to only what’s reasonably necessary-avoid blanket bans
• Choose a fair time period (6-12 months is typical; longer periods are rarely upheld unless justified)
• Restrict the clause to clients or staff that the person actually worked with, not everyone your business has ever dealt with
• Avoid penalising someone simply for working for a competitor, unless you have a separate non-compete that is also reasonable
• Review your contracts regularly-what was “reasonable” last year may not be today if business or industry circumstances change

In a nutshell: keep your clause focused, proportionate, and updated. If in doubt, ask a legal expert to review your agreements before issues arise.

What If You’re Asked to Sign a Non-Solicitation Clause?

Maybe you’re a founder selling your business, a consultant negotiating a contract, or a new hire at a company. Don’t just accept a non-solicitation clause without reading (and understanding) what it covers.

• Is the clause too broad, for too long, or does it lock you out of your entire industry?
• Does it stop you from contacting people who weren’t actually clients or staff you worked with?
• Could it hurt your future job or business prospects needlessly?

It’s okay to negotiate the terms or ask for clarification. You’re within your rights to request a reasonable reduction in scope or timeframe. If you’re unsure, get a contract reviewed by a lawyer before you sign-it can help you avoid surprises or disputes later on.

What Other Contracts and Policies Should Your Business Have?

Non-solicitation clauses are only one part of a strong legal setup. Most UK businesses will also need other agreements to stay protected and compliant, such as:

• Employment contracts
• Contractor and freelancer agreements
• Shareholder or partnership agreements
• IP and confidentiality clauses
• Supplier and client contracts

It can be daunting to know exactly which agreements and clauses are right for your situation, so don’t hesitate to chat with a legal expert who can help you get protected from every angle.

Key Takeaways: Getting Non-Solicitation Clauses Right

• Non-solicitation clauses help protect your business by stopping former employees, contractors, or partners from poaching your clients and staff after your contract ends.
• To be enforceable in the UK, a non-solicitation clause must be reasonable in terms of time, scope, and geography, and only go as far as needed to protect your real business interests.
• These clauses are different from non-compete agreements, as they bar “poaching” rather than all competition.
• Always draft non-solicitation clauses clearly, stating who is restricted, who is protected, how long the ban lasts, and what types of contact are covered.
• If you believe someone has breached this clause, gather evidence and get legal advice before taking action.
• Have all your business contracts-including non-solicitation clauses-reviewed regularly by a legal expert to keep them enforceable and up-to-date.
• Never sign a non-solicitation clause without reading, understanding, and (if needed) negotiating the details.
