A UK Non-Solicitation Agreement is a legally binding contract in which one party (the Recipient Party) agrees not to solicit, recruit, or poach the other party’s (the Disclosing Party’s) employees, clients, customers, or suppliers for a specified period and within a defined geographical area. Governed by the laws of England and Wales, a well-drafted non-solicitation agreement is an essential tool for businesses seeking to protect their most valuable commercial relationships.

Under English common law, non-solicitation clauses are classified as restrictive covenants and are subject to a strict enforceability test. Unlike in some civil law jurisdictions, restrictive covenants in England and Wales are presumed to be void as restraints of trade. The party seeking enforcement must prove that: (1) there is a legitimate business interest to protect, such as trade connections, client relationships, confidential information, or a stable workforce; and (2) the restriction goes no further than is reasonably necessary to protect that interest. This two-stage test was articulated in the foundational case of Nordenfelt v Maxim Nordenfelt Guns and Ammunition Co Ltd [1894] AC 535 and has been consistently applied in modern decisions including TFS Derivatives Ltd v Morgan [2005] IRLR 246.

The courts consider several factors when assessing the reasonableness of a non-solicitation restriction: the duration of the restriction, the geographical area covered, the categories of persons or entities covered (employees, clients, suppliers), and whether the restriction is linked to a sufficiently defined group of contacts with whom the Recipient Party had actual dealings. A restriction that is too wide in any of these respects risks being struck down, although English courts have shown willingness to apply the so-called ‘blue pencil’ test to sever unenforceable parts and preserve the remainder.

Non-solicitation agreements are routinely used in a range of business contexts in England and Wales: employment relationships, consultancy engagements, business sales and acquisitions, joint ventures, and distribution or agency arrangements. In each context, the specific interest being protected and the degree of the Recipient Party’s access to valuable business relationships will inform the appropriate scope of the restriction.

A Non-Solicitation Agreement should be used whenever a business relationship creates a risk that one party might leverage access to the other party’s employees, client relationships, or supplier network for competitive advantage. Common situations in England and Wales include:

During employment or consultancy engagements, where a consultant, contractor, or senior employee gains detailed knowledge of the client’s most valuable client accounts, pricing strategies, and operational staff. A non-solicitation clause in the employment or consultancy contract prevents that person from using that knowledge to poach clients or colleagues after the relationship ends.

In the context of a business sale or acquisition, where the seller has built up a client base and goodwill that the buyer is paying to acquire. A non-solicitation (and often a non-compete) clause in the sale agreement protects the buyer from the seller immediately approaching former clients. The courts have historically been more willing to enforce broad restrictions in business sale contexts because the seller has received consideration for the goodwill.

In joint venture or partnership arrangements, where one party gains access to the other’s commercial contacts and trade relationships. A non-solicitation clause protects against a party using joint access to contacts to develop competing business after the venture ends.

In distribution, agency, or reseller arrangements, where the distributor or agent builds relationships with the principal’s end customers. A non-solicitation clause prevents the agent from approaching those customers directly after termination of the arrangement.

When sharing confidential client or supplier information with third parties in the context of negotiations, due diligence, or commercial discussions. A non-solicitation agreement (often combined with a non-disclosure agreement) protects against misuse of that information even if no transaction is ultimately completed.

A well-drafted UK Non-Solicitation Agreement for England and Wales should contain the following key provisions:

Party Identification — Full legal names, entity types, and registered addresses of both parties. Correctly identifying the legal entities is important because non-solicitation obligations bind specific legal persons, not associated group companies, unless the agreement expressly extends to affiliates.

Business Context — A recital or background clause describing the commercial relationship that gives rise to the non-solicitation obligation. Courts are more likely to enforce a restriction if the legitimate business interest being protected is clearly identified from the face of the agreement.

Non-Solicitation of Employees — A prohibition on directly or indirectly recruiting, soliciting, or hiring the Disclosing Party’s employees or contractors, for a specified period after the relationship ends. The restriction should ideally be limited to employees with whom the Recipient had actual contact, to ensure it is no wider than necessary.

Non-Solicitation of Clients and Customers — A prohibition on approaching, canvassing, or accepting business from the Disclosing Party’s existing clients and, in some cases, prospective clients with whom the Recipient had material contact during the relationship. The protectable interest here is the goodwill and trade connections of the business.

Non-Solicitation of Suppliers and Business Partners — An optional prohibition on interfering with the Disclosing Party’s key supplier relationships. This is particularly relevant in businesses where supplier relationships represent a significant competitive advantage.

Geographical Scope — The area within which the restriction applies. A restriction that is limited to the Disclosing Party’s actual trading area is more likely to be enforced than one that is stated to apply worldwide.

Restriction Period — The duration of each restriction after the relationship ends. Courts in England and Wales have enforced periods of up to 12–24 months in commercial and post-employment contexts, depending on the circumstances.

Severability and Reduction — A mechanism allowing the courts to sever or reduce any restriction that is found to be unreasonably broad, without invalidating the remainder of the agreement.

Injunctive Relief — An express acknowledgement that breach would cause irreparable harm, supporting the Disclosing Party’s application for an injunction without needing to prove actual loss.

Governing Law — Confirmation that the agreement is governed by the laws of England and Wales, with exclusive jurisdiction in the courts of England and Wales.
