Introduction
A non solicitation agreement for employees is a key protective measure used by businesses across England and Wales. It is designed to prevent departing employees from taking unfair advantage of relationships built during their employment. In competitive markets, where client connections and team stability are vital, these agreements can make a significant difference.
At Blackstone Solicitors, we regularly advise employers and employees on restrictive covenants, including non solicitation clauses. When properly drafted, these provisions can offer effective protection without placing unreasonable limits on an individual’s ability to work. When poorly drafted, they can be difficult to enforce and may lead to disputes.
This article explains what a non solicitation agreement is, how it works in practice, and what both employers and employees should consider.

What Is a Non Solicitation Agreement?
A non-solicitation agreement is a contractual provision that restricts an employee from approaching certain individuals or businesses after their employment ends. Typically, this includes clients, customers, and sometimes other employees.
The aim is to prevent a former employee from using relationships developed during their employment to benefit a competing business or a new venture.
Unlike a non-compete clause, which restricts where or how a person can work, a non-solicitation clause is more targeted. It focuses on specific interactions rather than limiting employment altogether. For this reason, it is often more likely to be enforceable.
Why Employers Use Non Solicitation Clauses
Protecting Client Relationships
Many businesses invest considerable time and resources in building strong client relationships. Employees often play a central role in maintaining these connections. Without a non-solicitation clause, a departing employee could approach those clients and encourage them to move elsewhere.
Preserving Workforce Stability
Some non-solicitation agreements extend to employees as well as clients. This prevents former employees from attempting to recruit colleagues to join a competing business. Such protection can be crucial where team cohesion is essential.
Safeguarding Confidential Information
While confidentiality clauses protect sensitive information directly, non-solicitation clauses provide an additional layer of protection by limiting how that information can be used in practice.
Are Non Solicitation Agreements Enforceable in the UK?
The Legal Framework
In England and Wales, non-solicitation agreements are subject to the restraint of trade doctrine. This means that they will only be enforceable if they:
- Protect a legitimate business interest
- Are reasonable in scope, duration, and application
Courts will not enforce restrictions that go beyond what is necessary. The burden is on the employer to justify the clause.
Why Non Solicitation Clauses Are Often Upheld
Compared to non-compete clauses, non-solicitation provisions are generally seen as less restrictive. They do not prevent an individual from working in their chosen field. Instead, they limit specific conduct.
As a result, courts are more willing to enforce them, provided they are properly drafted.
Legitimate Business Interests
For a non-solicitation agreement to be valid, the employer must identify a legitimate business interest. Common examples include:
- Existing client or customer relationships
- Prospective clients with whom the employee had dealings
- The stability of the workforce
- Confidential business information
A clause that seeks to prevent all forms of competition, without targeting a specific interest, is unlikely to succeed.
Key Elements of a Non Solicitation Clause
Definition of Solicitation
The clause should clearly define what constitutes solicitation. This may include direct contact, indirect approaches, or actions intended to encourage a client or employee to move.
Clarity is important. Disputes often arise where the wording is vague or open to interpretation.
Identifying the Restricted Parties
A well drafted clause will specify who the employee is not allowed to solicit. This might include:
- Clients or customers they dealt with personally
- Clients about whom they had confidential information
- Employees within a particular team or department
Overly broad definitions can weaken enforceability.
Duration of the Restriction
The length of the restriction must be reasonable. In many cases, periods of three to twelve months are common, depending on the nature of the role and the industry.
Longer periods may be justified for senior employees with significant influence over client relationships.
Geographic Scope
In some cases, the clause may include a geographic limitation. However, this is often less relevant for non-solicitation provisions, as the focus is on relationships rather than location.
Practical Examples
A sales manager leaves a company and joins a competitor. A non-solicitation clause may prevent them from contacting clients they managed during their previous role.
A senior consultant departs and starts a new business. The clause may stop them from approaching colleagues to join the new venture.
An account manager moves to a rival firm. They may be restricted from encouraging existing clients to transfer their business.
These examples illustrate how non solicitation clauses operate in practice. The key factor is the protection of established relationships.
Risks for Employers
Overly Broad Clauses
If a clause is too wide, it may be unenforceable. Courts will not rewrite the agreement to make it reasonable.
Employers should avoid blanket restrictions that cover all clients or employees without distinction.
Lack of Evidence
Enforcement requires evidence of solicitation. This can sometimes be difficult to prove, particularly where contact is indirect.
Failure to Update Contracts
Roles evolve over time. A clause that was reasonable when the contract was signed may no longer reflect the employee’s responsibilities. Regular reviews are essential.
Risks for Employees
Injunctions and Legal Action
If an employee breaches a non-solicitation agreement, the employer may seek an injunction. This can prevent further contact and may have immediate consequences for the employee’s new role.
Financial Liability
Employees may be required to compensate the employer for losses resulting from the breach. This can be significant in cases involving key clients.
Reputational Impact
Disputes involving restrictive covenants can affect professional reputation. This may have longer term implications for career progression.
Drafting a Non Solicitation Agreement
Tailor the Clause to the Role
A one size approach rarely works. The clause should reflect the employee’s actual duties and level of client interaction.
Keep It Proportionate
The restriction should go no further than necessary to protect the business. Excessive limitations increase the risk of unenforceability.
Use Clear Language
Ambiguity can lead to disputes. The clause should be precise and easy to understand.
Combine with Other Protections
Non solicitation clauses are most effective when used alongside confidentiality and non-dealing provisions. Together, they create a comprehensive framework.
Non Solicitation vs Non Dealing Clauses
It is important to distinguish between non solicitation and non-dealing clauses.
A non-solicitation clause prevents the employee from initiating contact. A non-dealing clause goes further by preventing any business interaction, even if the client makes the first approach.
Non dealing clauses are more restrictive and may be harder to enforce. Employers should consider carefully which approach is appropriate.
Challenging a Non Solicitation Clause
Employees who believe a clause is unreasonable may challenge it. Common arguments include:
- The clause is too broad in scope
- The duration is excessive
- There is no legitimate business interest
- The definition of solicitation is unclear
Each case will depend on its facts. Courts will assess the overall fairness of the restriction.
Enforcement in Practice
Early Action
Employers should act quickly if they suspect a breach. Delay can weaken the case and reduce the chances of obtaining an injunction.
Evidence Gathering
Clear evidence is essential. This may include emails, messages, or witness statements showing that solicitation has taken place.
Negotiation
Many disputes are resolved without court proceedings. Negotiated solutions can be quicker and more cost effective.
Practical Advice for Employers
Employers should take a strategic approach to non-solicitation agreements. Key steps include:
- Identify the relationships that need protection
- Draft clauses that are specific and proportionate
- Review contracts regularly
- Seek legal advice when necessary
A carefully considered approach will improve the chances of enforceability.
Practical Advice for Employees
Employees should be aware of their obligations before leaving a role. It is important to:
- Review the employment contract in detail
- Seek legal advice if unsure
- Avoid any conduct that could be seen as solicitation
- Communicate openly with a new employer about any restrictions
Taking these steps can reduce the risk of disputes.
Conclusion
A non-solicitation agreement for employees is a valuable tool for protecting business relationships and maintaining stability. When properly drafted, it strikes a balance between safeguarding legitimate interests and allowing individuals to continue their careers.
Enforceability depends on reasonableness, clarity, and a clear connection to a legitimate business interest. Both employers and employees should approach these clauses with care.
