What Counts as Diverting Business and Breaching Fiduciary Duty in the UK?
Diverting business occurs when a person in a position of trust—such as a company director, partner, or senior employee—improperly redirects clients, revenue, or commercial opportunities away from their current business, usually for personal benefit or for a competing enterprise. Under English law, these individuals owe strict fiduciary duties: to act in the best interests of the business, avoid conflicts, and not profit personally at the expense of their company or partners.
Breaches of fiduciary duty happen if a director, partner, or employee uses their role to secure advantages for themselves or others, rather than putting the business first. Common instances include:
- Secretly contacting and soliciting key clients or contracts to move to a new or rival business
- Diverting opportunities or tenders which arise in the role to themselves or related parties
- Providing confidential company information for competitive advantage
Careful analysis of the business structure and the actual role is key to establishing the existence of fiduciary duty and identifying any breach.
How Does Diverting Business Breach Fiduciary Duty Under English Law?
Directors, partners, and senior employees are legally prohibited from benefiting themselves at their principal’s expense. This is set out in key legal principles, starting with Keech v Sandford (1726) and now enshrined in the Companies Act 2006 (sections 171–177 for directors). Core obligations include:
- Avoiding conflicts of interest (Companies Act 2006, s.175)
- Declaring interests in transactions (s.177)
- Not making a personal gain from business opportunities arising in their role
Consequences include:
- A legal obligation to account for all profits from the diverted opportunities
- Injunctions to restrain further diversion
- Damages to compensate for proven business loss
A careful forensic review of communications, contracts, and digital records often uncovers key proof to establish a breach.
What Are Common Examples of Business Diversion and Breach of Duty?
Typical scenarios in England and Wales where business diversion and breaches of fiduciary duty arise include:
- Directors resigning and then encouraging high-value clients to move to their own start-up
- Employees resigning but soliciting customers during their notice or garden leave period
- Partners negotiating private deals with clients before formally leaving the firm
Early gathering of such evidence significantly strengthens a diverted trade claim.
When Does Diverting Business Become Unlawful?
Business diversion crosses the line into illegality under English law when it breaches an individual’s existing fiduciary obligation, employment agreement, or a specific non-compete clause. Key thresholds include:
- Actively soliciting clients or business before leaving employment or partnership
- Using confidential or proprietary information to compete unfairly
- Not disclosing a personal or competing interest while in an existing fiduciary role
If you believe business diversion has occurred, acting swiftly is crucial to preserve evidence and protect your commercial interests.
How Can You Prove and Quantify Losses from Diverted Business?
Successfully claiming for diverted business depends on solid evidence and demonstrating the resulting loss. The English courts expect claimants to:
- Collect Strong Evidence
- Retain emails, messages, call records, and documents proving contact or agreements with diverted clients.
- Secure physical and digital contracts, proposals, or invoices which point to changed client relationships.
- Establish Causation
- Show that loss or reduced income resulted specifically from the breach (not broader market trends).
- Use client statements or compare revenue data from before and after the alleged diversion.
- Quantify the Financial Impact
- Evidence what the business likely would have earned but for the diversion, using historic turnover, average client value, or missed tenders.
- For significant claims, engage a forensic accountant to construct a detailed calculation, particularly where lost profits or complex contracts are involved.
- Account for Profits
- Claim an “account of profits” where precise loss is difficult to prove but measurable gain accrued to the wrongdoer.
Key Documentation:
- Management accounts, historic client revenue, and CRM data
- Evidence of new contracts entered by the suspected party (often compelled through court disclosure)
- Witness statements or client confirmations

What Steps Should I Take If I Suspect a Director, Partner, or Employee of Diverting Trade?
If you suspect business diversion or breach of fiduciary duty, take these decisive steps to avoid further harm:
- Preserve Evidence
- Secure all relevant emails, devices, company servers, and paper files.
- Restrict access to sensitive systems or data.
- Conduct an Internal Investigation
- Launch a confidential (and often HR-led) investigation to identify loss patterns or suspicious communications.
- Avoid alerting the suspected party prematurely.
- Obtain Immediate Legal Assessment
- Instruct a commercial litigation specialist to evaluate your legal position, possible remedies, and scope for interim orders.
- Pursue Without Prejudice Negotiations
- Engage constructively with the other party where appropriate to resolve or disclose issues early, without waiving your rights.
Contact our expert lawyers as soon as concerns arise. Early legal intervention is often decisive in avoiding protracted litigation.
How Enforceable Are Non-Compete Clauses and Restrictive Covenants in England and Wales?
Non-compete clauses and restrictive covenants serve as vital protection against diversion of clients after a director, partner, or employee leaves. However, to be legally enforceable in England and Wales, they must be:
- Carefully drafted to protect a legitimate business interest (such as confidential information, client relationships, or goodwill)
- Reasonable in terms of geographic area, duration, and overall scope
- Not so broad as to amount to an unfair restraint of trade
Our lawyers offer contract reviews and practical advice for both enforcing and resisting restrictive covenants.

What Laws and Deadlines Apply to Diverted Business and Fiduciary Duty Claims?
Business diversion and fiduciary duty claims rely on a combination of statutory and common law duties, including:
- Companies Act 2006: Core duties for directors (sections 171–177)
- Partnership Act 1890: Fundamental obligations for partners (sections 28–30)
- Equitable Principles: Extend to senior employees and informal (shadow) directors
- Contract Law: Specific employment or partnership contract provisions
Limitation Periods
- Breach of Fiduciary Duty: Six years from breach (Limitation Act 1980, s.21), with no limitation for fraud claims.
- Contractual Breach: Six years from the event (s.5, Limitation Act 1980).
- Equitable Claims (Account of Profits): Potentially longer—subject to facts, particularly where fraud or concealment delayed discovery.
A solicitor will be able to advise on claims, deadlines, and the correct forum according to your situation.
What Do the Courts Say About Diverting Business and Breach of Fiduciary Duty?
English courts provide detailed guidance via precedent on how diverted business and fiduciary duty breach cases are assessed and remedied.
| Case | Facts | Outcome | Why It Matters |
|---|---|---|---|
| CMS Dolphin Ltd v Simonet [2001] 2 BCLC 704 | Director resigned and diverted a major client to his new company. | Director ordered to account for all profits made from the diverted business. | Shows that directors cannot appropriate business opportunities for themselves after leaving office. |
| FHR European Ventures LLP v Cedar Capital Partners LLC [2014] UKSC 45 | Fiduciary obtained secret commission during a transaction. | Profits held on constructive trust for the principal. | Affirms that profits derived from breach must be repaid to the business. |
| Neptune (Vehicle Washing Equipment) Ltd v Fitzgerald [1996] FSR 432 | Employee prepared to compete using business information before leaving. | Business granted injunction and damages. | Demonstrates that misuse of confidential info before exit is actionable. |
Remedies routinely include account of profits, compensatory damages, and injunctions to prevent further harm.

What Defences Are Available to Claims of Business Diversion in the UK?
Anyone accused of diverted trade or breach of fiduciary duty can contest a claim with several common defences. Successful arguments include:
- No duty was owed (e.g. individual was not a director or partner at the relevant time)
- Actions taken were preparation for lawful future competition only—not actual diversion before departure
- Actions were taken with the informed consent or express authority of the business or principal
- The real cause of loss was unrelated (e.g. client chose to leave for external reasons)
- The claimant accepted or acquiesced in the behaviour at the time
If you have received a claim or threat regarding business diversion, our expert lawyers can confidentially review your risks and options.

Frequently Asked Questions
Can a director run a competing business while still in office?
No. Directors are bound by strict non-compete and loyalty duties (Companies Act 2006, s.175), prohibiting them from setting up or running rival businesses without clear board or shareholder consent. Breach exposes them to removal, orders to account for profits, and interim injunctions.
How do I get evidence if I suspect business is being diverted?
Act as soon as possible: secure all emails, device records, client communications, and digital CRM data. It may be necessary to appoint forensic IT experts to recover deleted material. If critical evidence is controlled by the wrongdoer, courts can order urgent disclosure to preserve your claim.
Is there always a contract breach if a partner takes clients?
Not necessarily. The existence and scope of a contractual or fiduciary duty should be established first, along with clear proof that the alleged conduct actually breached it (such as by soliciting clients before leaving or misusing partnership property). Each scenario depends on its facts.
Are interim injunctions available for diverted business?
Yes, where there is imminent risk of further damage, the courts can grant interim injunctions on an urgent basis to restrain further business diversion or misuse of confidential information. Fast, decisive evidence is needed to convince the court.
Can I recover profits lost in the future, not just what’s already missing?
Yes, provided credible evidence shows—on the balance of probability—that those profits would likely have been realised but for the breach. Courts use client history, projected value, and expert analysis to assess these wider losses.
What’s the typical cost and timeline for a fiduciary duty claim?
Costs and timelines depend on complexity. High Court proceedings often last 9–18 months, with total legal costs ranging from £40,000 to £150,000+ for larger claims. We provide fixed-fee initial reviews and clear phases to help you plan.
How does prior shareholder agreement affect my claim?
Shareholder agreements can extend, supplement, or modify statutory and fiduciary responsibilities. Review these with any potential claim—many include special procedures or bespoke remedies in the event of a breach.
What happens if I wait too long to take action?
Delayed action risks losing your right to damages due to statutory limitation, or reduces the chance of urgent remedies such as injunctions. It can also make it harder to locate and secure evidence of loss.
Can restrictive covenants be challenged in court?
Yes. English courts assess all restrictive covenants for fairness and proportionality, often reducing or striking out those that are unreasonably wide or onerous.
Will the court consider the employee’s or director’s intention?
Intent is one aspect of the court’s assessment, but even unintentional or careless breaches of objective legal duties can result in liability. Deliberate and concealed breaches, on the other hand, often attract the most serious remedies.
