Fiduciary Duties In The UK Explained

If you run a limited company, partnership or fast-growing startup in the UK, you’ll hear the word “fiduciary” sooner or later. It sounds technical, but it boils down to this: certain people in your business have legal duties to act in someone else’s best interests - and if they don’t, the consequences can be serious.

In practice, fiduciary duties touch everyday decisions: approving a supplier contract when a director has a stake in that supplier, handling confidential information, negotiating an exit with investors, or hiring a contractor who could divert opportunities away from your company.

In this guide, we’ll unpack what “fiduciary” means under UK law, who owes these duties in a small business, the practical rules you should follow, and the steps to manage conflicts and reduce risk from day one.

What Is A Fiduciary (And Why Does It Matter To Your Business)?

A fiduciary is someone who has agreed (expressly or by their role) to act for or on behalf of another person or organisation in circumstances that give rise to trust and confidence. In a small business context, the most common fiduciaries are company directors and partners. Agents - including senior employees who negotiate deals - can also owe fiduciary duties in certain situations.

Fiduciary duties require loyalty, honesty and putting the beneficiary’s interests first. That means prioritising the company over personal gain, avoiding conflicts, not exploiting business opportunities for yourself, and keeping confidences. These duties sit alongside other legal obligations (such as statutory director duties in the Companies Act 2006 and the duty of reasonable care and skill) and can overlap with contract terms you’ve agreed with stakeholders.

Why it matters: breaches can result in personal liability, an account of profits (handing over what was gained), rescission of deals, court injunctions and, in serious cases, disqualification from acting as a director. Getting this right protects your company’s value, reputation and relationships with investors, customers and partners.

Who Owes Fiduciary Duties In A UK Small Business?

Directors (Including De Facto And Shadow Directors)

All registered directors of a UK company are fiduciaries. UK law also looks past job titles: individuals who act like directors (de facto directors) or whose directions the board habitually follows (shadow directors) may also owe fiduciary duties. If you’re the founder in practice “calling the shots” without being formally appointed, the court can still treat you as a fiduciary.

Directors’ statutory duties under the Companies Act 2006 significantly overlap with fiduciary obligations. These include:

• Acting within powers (s.171) and in line with the company’s Articles of Association.
• Promoting the success of the company for the benefit of its members as a whole (s.172) - consider long-term consequences, employees, suppliers, customers, community and the environment.
• Exercising independent judgment (s.173) and reasonable care, skill and diligence (s.174).
• Avoiding conflicts of interest (s.175) and not accepting benefits from third parties (s.176).
• Declaring interests in proposed transactions or arrangements (s.177).

Partners And LLP Members

Partners in a traditional partnership owe fiduciary duties to each other and to the partnership, including a duty of utmost good faith and not to make a secret profit or compete without consent. LLP members also owe duties, though the exact scope often turns on the LLP agreement and the member’s role.

Agents And Senior Employees

Agents (anyone authorised to act on your behalf) are fiduciaries as to the matters within their authority. Senior employees who negotiate and enter contracts, or who have managerial discretion, may owe fiduciary duties in addition to contractual and common law duties of fidelity and confidence. Be mindful that employees can sometimes bind your company to deals - tightening internal guidelines around authority to bind the company is a simple risk control.

Core Fiduciary Rules You Need To Manage Day-To-Day

Avoid Conflicts Of Interest

A conflict arises when a fiduciary’s personal interests, or duties owed elsewhere, clash (or could reasonably be seen to clash) with the company’s interests. Classic examples include taking a side business opportunity, steering contracts to a connected party, or sitting on two boards with competing strategies.

Practical steps:

• Require early, written disclosure of any actual or potential conflicts and record them in a register.
• Adopt and enforce a plain-English Conflict of Interest Policy with clear approval thresholds, recusal rules and reporting lines.
• Use board approvals where appropriate and minute the decision-making process at your directors’ meetings (who declared what, who abstained, why the decision promotes the company’s success).

Not To Profit From Position (Unless Properly Authorised)

Fiduciaries must not make a secret profit from their position. If a director personally benefits from a corporate opportunity or related-party deal without proper disclosure and authorisation, the company can claim those profits. Build simple guardrails:

• Pre-authorise limited, clearly defined situations (e.g. reasonable market-rate consultancy fees) via your Directors’ Service Agreement and company policies.
• Where a director has an interest, ensure disclosure and, if necessary, obtain board or shareholder approval as required by your Articles and the Companies Act.

Duty Of Confidentiality

Fiduciaries must preserve confidential company information and not use it for personal gain. In practice, that means protecting trade secrets, customer data, pricing strategies and deal terms, even after someone leaves. Robust confidentiality clauses in employment and consultancy contracts, access controls and a clean handover on exit all help minimise risk.

Act In Good Faith And For Proper Purposes

Fiduciaries should act honestly, in good faith, and for the company’s proper purposes (e.g. issuing shares to raise capital, not to dilute a rival founder). Minutes should show the rationale behind key decisions and how they align with the company’s interests.

How To Structure And Document Fiduciary Responsibilities

Getting your framework in place early reduces ambiguity and helps everyone do the right thing. Here’s a pragmatic setup for most SMEs.

1) Appoint Directors Properly And Define Their Role

Make formal board appointments and issue role descriptions. Align expectations in a tailored Directors’ Service Agreement covering duties, confidentiality, conflicts, decision-making, remuneration, expenses and post-termination restrictions. Avoid informal “advisor” roles that look and behave like directorships without the paperwork - you can accidentally create de facto or shadow directors.

2) Put A Shareholders Agreement In Place

A well-drafted Shareholders Agreement complements statutory duties by setting clear rules on reserved matters, related-party transactions, information rights, new share issues, and what happens if someone wants to leave. It’s also the right place to spell out processes for handling conflicts, deadlocks, and competitive activities by founders or investors.

3) Tighten Your Constitution And Board Procedures

Review your Articles for conflict authorisation mechanisms, quorum, voting and disclosure requirements. Encourage disciplined decision-making with regular, well-minuted directors’ meetings and written resolutions when needed. Where conflicts exist, ensure the interested director abstains if required by the Articles or law.

4) Implement A Simple Conflicts Framework

Adopt a Conflict of Interest Policy, keep a live conflicts register, and train your leadership team to disclose early. For recurring scenarios (e.g. a director who also provides consultancy services), set capped pre-approvals and require periodic review.

5) Clarify Who Can Bind The Company

Limit who can sign contracts and on what terms. Use signing authorities, two-signature rules for higher values, and clear internal guidance on authority to bind the company. This reduces the risk that an employee or consultant creates obligations that conflict with company interests.

6) Manage Dual Roles Carefully

Founders often wear multiple hats - director, employee, and shareholder. Each hat brings different duties and incentives. Get clarity early on remuneration, KPIs, bonus schemes, and time commitments if you hold a director and employee role so decisions remain anchored to the company’s interests.

Handling Common Conflict Scenarios (Without Derailing The Business)

Conflicts don’t automatically mean wrongdoing - but they must be identified, disclosed and handled properly. Here are examples you’ll likely face, plus practical steps that keep you compliant and commercial.

Scenario 1: Contracts With Connected Parties

Suppose your director owns a logistics company you want to engage. Steps to take:

• Full written disclosure of the interest and any benefits (fees, commissions, equity).
• Obtain independent quotes to benchmark commercial terms and document your assessment.
• Remove the interested director from negotiations and decision-making; minute the process.
• Where required by your Articles or Part 10 of the Companies Act, obtain board or shareholder approval.

Scenario 2: Corporate Opportunities

A director discovers a potential customer contract that fits your company’s strategy. The director must present the opportunity to the company - not pursue it personally - unless the company, after proper disclosure, declines it. This should be recorded in the minutes and, if recurring, addressed in the director’s service terms and your conflicts policy.

Scenario 3: Competing Activities

If a founder wants to launch a side project in a similar space, there is a real risk of breach unless the company authorises it in advance. You might agree to carve-outs with guardrails (no solicitation of staff, no use of confidential information, no competing products for 12 months, etc.) and document this through the Shareholders Agreement and director’s contract.

Scenario 4: Personal Benefits And Hospitality

Gifts, travel or entertainment from suppliers can create perceived or actual conflicts. Set a threshold for reporting and approval, keep a gifts/hospitality register, and err on the side of disclosure. Reminder: the Companies Act duty not to accept benefits from third parties (s.176) is strict in many contexts.

What Happens If Fiduciary Duties Are Breached?

Courts take fiduciary obligations seriously. Potential consequences include:

• Account of profits: the fiduciary must hand over gains made from the breach, even if the company did not suffer direct loss.
• Rescission: undoing a contract tainted by the breach (e.g. a self-dealing transaction) where practical.
• Damages or equitable compensation: to put the company back in the position it should have been in.
• Injunctions: preventing further misuse of confidential information or diversion of opportunities.
• Removal or disqualification: from office in serious cases.

If you suspect a breach, move quickly: preserve evidence, convene the board (excluding interested parties), get independent advice, and decide on remedies or negotiated resolution. Ensure your governance house is in order - your Articles, board procedures and records of directors’ meetings can make or break your position.

Practical Compliance Checklist To Stay On The Right Side Of Fiduciary Law

Here’s a straightforward framework you can action this quarter.

1) Document Roles And Relationships

• Formalise board appointments, write role descriptions, and issue a tailored Directors’ Service Agreement for each director.
• Map who can make decisions and sign contracts; limit and record delegations of authority.

2) Strengthen Governance

• Update your Articles to ensure clear conflict authorisation processes and voting rules aligned with the Companies Act.
• Adopt simple board protocols, a conflicts register and regular minuted meetings.
• Lock in a comprehensive Shareholders Agreement to handle related-party deals, decision rights and exits.

3) Train And Embed Culture

• Run a short onboarding for directors and senior staff on duties, disclosure, and decision-making standards.
• Make your conflicts and confidentiality rules practical and visible - not a policy that gathers dust.

4) Manage Dual Roles And Interests

• Address director and employee overlaps in writing, including performance expectations and time commitments.
• Pre-clear any side ventures or advisory positions, with recusal and information barriers where needed.

5) Record, Record, Record

• Keep clean minutes, decision papers and approval records, especially for conflict-sensitive decisions.
• Store disclosures and approvals with your conflicts register and board packs.

6) Don’t DIY Complex Situations

• High-stakes matters (fundraising, M&A, related-party deals) often raise fiduciary issues. Get tailored advice before committing.
• Ensure your processes align with your Articles of Association and statutory requirements - procedural missteps can void approvals.

FAQs: Fiduciary Duties In Everyday Founder Life

Do All Directors Have The Same Duties?

Yes, the Companies Act duties apply to all directors. However, expectations around care, skill and diligence (s.174) are partly objective and partly subjective - what’s “reasonable” considers your actual knowledge and experience. A finance-experienced director will typically be expected to spot financial red flags earlier than others.

Can We Authorise A Conflict So A Deal Can Proceed?

Often, yes - if your Articles allow it and you comply with disclosure and approval requirements. The conflicted director should not vote where abstention is required. For larger or sensitive transactions, consider shareholder approval and, where appropriate, independent valuations or benchmarking.

What If A Director Finds An Opportunity Outside Board Time?

Timing doesn’t decide ownership. If the opportunity is in the company’s line of business or arises from a director’s position or information, it’s generally the company’s to accept or refuse after disclosure. Only pursue it personally if the company properly declines and you have obtained any required approvals.

How Do We Reduce The Risk Of Employees Accidentally Binding Us?

Use clear internal signing limits, contract playbooks and countersignature processes. Teach teams who can commit the company and in what circumstances. For extra protection, specify who has authority in supplier communications and templates, and refresh knowledge on authority to bind the company.

Key Takeaways

• In the UK, directors, partners and agents can be fiduciaries - they must act loyally, avoid conflicts, not profit from their position without consent, and protect confidential information.
