Are Non‑poaching Agreements Legal in the UK? CMA Guidance, Penalties and Safe Hiring (2026)

Are non‑poaching agreements legal in the United Kingdom? In most cases the answer is no, and the risk of enforcement action has never been higher. On 9 September 2025 the Competition and Markets Authority (CMA) published its Competing for Talent guidance, placing no‑poach pacts and wage‑fixing squarely at the top of its enforcement agenda. The guidance confirms that naked agreements between competing employers not to hire or solicit each other’s staff are treated as restrictions of competition “by object” under the Competition Act 1998, carrying the same legal gravity as price‑fixing cartels.

This article provides a definitive 2026 compliance playbook for in‑house counsel, HR leaders and general counsel operating in the UK: the legal framework, practical red flags, safe‑harbour alternatives for information sharing in hiring, penalty thresholds, and step‑by‑step escalation workflows.

Short Answer, Are Non‑Poaching Agreements Legal?

The short answer is that standalone, competitor‑to‑competitor no‑poach agreements are almost certainly unlawful under UK competition law. A narrow exception exists where a no‑poaching clause is genuinely ancillary to a wider legitimate transaction, such as a merger, joint venture or outsourcing arrangement, and meets a strict necessity and proportionality test. Outside that exception, such agreements are void and expose the parties to significant fines and damages.

Key takeaway decision tree:

• Naked no‑poach between competitors → Presumed unlawful by object. No efficiency defence is likely to succeed.
• No‑poach clause ancillary to a broader collaboration → May be lawful if it is genuinely necessary for, and proportionate to, the main agreement and is limited in scope, duration and the roles it covers.
• Unilateral internal policy not to cold‑call a specific client’s staff → Lower risk, but could still raise concerns if part of a wider pattern of coordinated behaviour.

Three immediate actions for HR and compliance teams:

1. Pause, suspend any existing inter‑company hiring agreements or informal understandings pending review.
2. Review, audit all recruitment contracts, staffing‑agency agreements and joint‑venture workforce clauses for no‑poaching language.
3. Escalate, obtain specialist competition‑law advice before entering, renewing or continuing any arrangement that limits where, how or whom your competitors may hire.

Legal Framework: Competition Act 1998, Article 101 TFEU and CMA Enforcement

Understanding whether non‑poaching agreements are legal requires familiarity with two overlapping bodies of law, UK domestic competition legislation and the residual influence of EU antitrust principles, together with the enforcement machinery operated by the CMA.

Competition Act 1998, The Core Legal Test

The Competition Act 1998 contains two prohibitions that matter here. The Chapter I prohibition (section 2) outlaws agreements between undertakings that have as their object or effect the prevention, restriction or distortion of competition within the United Kingdom. A no‑poach agreement between rival employers restricts competition in the labour market, suppressing the normal process by which workers receive competing offers and employers bid for talent.

Agreements caught by the Chapter I prohibition are automatically void and unenforceable. There is no need for the CMA to prove that actual competitive harm resulted; an anti‑competitive object is sufficient. Where the CMA classifies conduct as a “by object” infringement, as it does with naked no‑poach antitrust violations, the evidential burden on the authority is considerably lighter.

Section 36 of the Competition Act 1998 further empowers the CMA to impose financial penalties of up to 10 % of an undertaking’s worldwide turnover for the most serious infringements, and the Enterprise Act 2002 adds criminal sanctions for individuals involved in certain cartel conduct.

Article 101 TFEU, EU Influence and Comparative Context

Although the UK has left the European Union, Article 101 of the Treaty on the Functioning of the European Union remains highly relevant for two reasons. First, many UK employers also operate across EU member states and must comply with both regimes. Second, UK courts and the CMA continue to draw on EU case law and guidance when interpreting the Chapter I prohibition.

A European Commission policy brief on labour‑market agreements has confirmed that no‑poach and wage‑fixing pacts between competitors are capable of restricting competition by object under Article 101. The policy brief explicitly likens such arrangements to market‑allocation cartels, businesses dividing a market for labour rather than for goods.

CMA Role and Enforcement Tools

The CMA is the principal UK enforcer. Its toolkit for no‑poach antitrust cases includes:

• Market studies and sector reviews, identifying industries where labour‑market restrictions are prevalent.
• Dawn raids, unannounced on‑site inspections to gather evidence of anti‑competitive agreements.
• Civil fines, up to 10 % of worldwide group turnover per infringement year.
• Director disqualification orders, under the Company Directors Disqualification Act 1986, directors may be barred for up to 15 years.
• Facilitation of private damages claims, third parties (including affected employees) may bring follow‑on claims in the Competition Appeal Tribunal.

CMA “Competing for Talent” Guidance, What Employers Must Know

The CMA published its Competing for Talent guidance on 9 September 2025, signalling an enforcement step‑change. The guidance makes clear that the CMA treats labour markets with the same seriousness as product markets, and that employers who agree not to poach or hire each other’s workers face the full range of competition‑law sanctions.

Headline points from the competing for talent guidance include:

• No‑poach agreements, any agreement, understanding or concerted practice between employers not to approach, recruit, offer employment to or hire each other’s staff is capable of infringing the Chapter I prohibition.
• Wage‑fixing, competitors that agree on pay levels, pay caps, salary bands or benefits packages are engaging in conduct equivalent to price‑fixing.
• Information sharing in hiring, exchanging competitively sensitive information about current or future pay rates, planned hiring volumes or recruitment strategies with rival employers may itself constitute an infringement, even without a formal agreement.
• Industry‑wide blanket arrangements, sector codes, trade‑association “gentlemen’s agreements” and informal understandings not to recruit across firms are all caught.

CMA Enforcement Signals and Sector Focus

Since publishing the guidance the CMA has used public communications, including social media posts and industry webinars, to reinforce the message. Industry observers expect the CMA’s 2026–27 enforcement programme to include at least one formal investigation into labour‑market conduct, particularly in sectors where skilled‑worker shortages create the strongest incentive for no‑poach arrangements, such as technology, financial services, healthcare and engineering.

How Non‑Poach Agreements Distort Labour Markets

The economic rationale underpinning the CMA no‑poach enforcement stance is well documented. Oxera’s analysis demonstrates that no‑poach agreements suppress wages by reducing the competitive pressure that forces employers to offer attractive packages. Without the threat that a rival will recruit their best people, employers have less incentive to raise pay, improve conditions or invest in retention. The result is a transfer of value from workers to employers, and a less efficient allocation of talent across the economy. Where multiple firms in a sector participate, the cumulative effect on wages can be substantial and lasting, particularly for specialist roles where alternative employment options are already limited.

Practical Red Flags and HR Compliance Checklist

Identifying whether your organisation is exposed to no‑poach antitrust risk requires a structured review of both formal contracts and informal practices. The following red‑flag table and checklist is designed for HR leaders and general counsel.

Example Scenarios That Trigger Risk

• Multi‑firm hiring cartel. Three technology companies in the same city agree informally that none of them will approach each other’s software engineers. Each firm benefits from reduced recruitment costs but workers lose the wage premium that competitive bidding would deliver. This is a textbook no‑poaching clause violation.
• Recruiter swap arrangement. Two professional‑services firms share a staffing agency and instruct it not to place candidates from one firm with the other. The agency instruction is evidence of a concerted practice.
• JV workforce allocation. A joint venture between two construction firms includes a clause preventing either parent from recruiting JV secondees for five years after the venture ends. The clause may be ancillary to the JV itself, but a five‑year, all‑role restriction is unlikely to survive a proportionality assessment.

Industry observers expect the CMA to pay particular attention to non‑solicitation clauses in staffing‑agency agreements, given that these arrangements are widespread and often escape internal compliance review. In‑house teams should treat agency agreements as a priority audit target.

Lawful Information Sharing and Safe Hiring Practices in the UK

Not all employer interaction about workforce matters is unlawful. The key distinction is between coordinated conduct that restricts competition and independent, properly anonymised market intelligence.

Permitted Benchmarking vs Illicit Wage‑Fixing

Salary benchmarking is legitimate, and often essential for competitiveness, provided it is structured safely:

1. Use a neutral, independent third‑party provider to collect and aggregate data.
2. Ensure data is anonymised so that no individual employer’s pay decisions can be identified.
3. Require a minimum number of participants (typically five or more) before results are shared.
4. Limit the recency of data, avoid real‑time or forward‑looking pay information.
5. Never share future hiring plans, planned salary changes or recruitment strategies directly with a competitor.

Recruitment Communications, Avoiding Coordination

HR professionals frequently attend industry events, conferences and networking forums. The following micro‑workflow applies when approached by a competitor about hiring:

1. Recognise the risk, any conversation about “not competing for staff” or “keeping pay in line” is a red flag.
2. Disengage immediately, politely end the discussion and change the subject.
3. Document the approach, record the date, the person involved, the company and the substance of what was said.
4. Report internally, notify your compliance officer or legal team within 24 hours.
5. Cooperate with any investigation, early self‑reporting to the CMA through its leniency programme can significantly reduce penalties.

Penalties, Remedies and Enforcement Examples

The maximum fine for breaching competition law under the Competition Act 1998 is 10 % of the infringing undertaking’s worldwide group turnover for each year of infringement. For large multinationals the sums involved can be enormous. Beyond financial penalties, the consequences include:

• Voided agreements, any no‑poaching clause caught by the Chapter I prohibition is automatically void and unenforceable.
• Director disqualification, individuals can be disqualified from acting as company directors for up to 15 years under the Company Directors Disqualification Act 1986.
• Criminal prosecution, while rare, the Enterprise Act 2002 provides for criminal penalties (including imprisonment) for individuals who participate in cartel agreements. The likely practical effect of the CMA’s signalling is that prosecutors will assess whether no‑poach arrangements in particularly egregious cases meet the cartel‑offence threshold.
• Reputational damage, CMA investigations are public, and infringement decisions are published in full.

Damages Risk and Private Litigation

Employees and former employees harmed by anti‑competitive hiring practices can bring follow‑on damages claims in the Competition Appeal Tribunal once the CMA has made an infringement finding. Early indications suggest that the plaintiffs’ bar, particularly specialist competition‑damages firms, is preparing to bring such claims in the UK, following the model of large‑scale no‑poach damages cases that have already been litigated in the United States. The financial exposure from a successful damages action compounds the regulatory fine significantly.

Drafting Safe Alternatives to a Naked No‑Poach

Where a genuine business need exists to protect confidential information, client relationships or a joint‑venture workforce, carefully drafted restrictive clauses can still be lawful, provided they pass the ancillary‑restraint test.

Ancillary‑Restraint Checklist

Drawing on ancillary‑restraint analysis, the following conditions must all be met:

1. Directly related, the restriction must be directly connected to the implementation of a main agreement (e.g., a merger, JV or outsourcing contract).
2. Objectively necessary, the main agreement could not be implemented without the restriction.
3. Proportionate in scope, limited to specific roles, geographies and a defined time period (typically no more than 12–24 months).
4. Not the primary purpose, the restriction must be subordinate to the main commercial objective.

Comparison: Clause Types, Risk and Use Cases

Comparison: Non‑Compete vs No‑Poach vs Non‑Solicit

Confusion between these three types of restrictive covenant is common. The difference between a non‑compete and a no‑poach is fundamental to assessing legal risk, because each engages a different body of law.

When to Seek Legal Advice, Escalation Triggers

The following situations should trigger an immediate referral to specialist competition counsel:

• M&A or JV transactions, any deal document that includes workforce restrictions (non‑solicit, no‑poach, salary alignment).
• Inter‑company HR discussions, if another employer proposes a hiring agreement, salary alignment or shared recruitment restriction.
• Industry hiring agreements, if a trade association or industry group circulates a code or protocol affecting recruitment.
• Internal audit findings, if your compliance review uncovers existing no‑poaching clauses or informal understandings.
• Leniency consideration, if your organisation has already been party to a no‑poach arrangement, early self‑reporting to the CMA under its leniency programme may significantly reduce or eliminate penalties.

Internal escalation form, fields to capture:

1. Name and role of the person reporting
2. Date and location of the approach or discovery
3. Counterparty organisation(s) involved
4. Nature of the information shared or the agreement proposed
5. Any documents, emails or messages evidencing the contact

Conclusion, Are Non‑Poaching Agreements Legal in 2026?

For UK employers the position is clear: naked no‑poach agreements between competitors are unlawful, carry severe penalties, and are a stated enforcement priority for the CMA following its Competing for Talent guidance of 9 September 2025. The question of whether non‑poaching agreements are legal can only receive a qualified “yes” in the narrow circumstance where a clause is genuinely ancillary to a wider legitimate transaction and satisfies strict tests of necessity, proportionality and limited duration. In every other case the legal, financial and reputational risk is acute.

HR teams and general counsel should treat the compliance steps outlined in this article as a baseline, and seek specialist competition‑law advice before entering, continuing or renewing any arrangement that touches on cross‑employer hiring restrictions.
