The Role and Duties of a Company Director

The duties of a director of a UK limited company are set out in law, and they apply from the moment of appointment. Under the Companies Act 2006, every company director owes seven general duties to the company, covering how decisions must be made, how personal interests must be managed, and what standard of conduct the law expects. Understanding these obligations before taking on a director’s role can prevent serious problems down the line. 

What Is a Company Director?

A company director is the person appointed to manage a limited company’s affairs and act as its legal officer. Every private limited company must have at least one director who is a natural person aged 16 or over. There is no requirement to hold shares, though in owner-managed businesses, the director and sole shareholder are often the same individual.

The director’s role is legally distinct from that of a shareholder. Shareholders own the company; directors run it. The legal obligations attached to each position remain separate, even when one person fills both roles. A director acts as the company’s agent, and the law holds them to a high standard of conduct because of that authority. Before making an appointment, it is worth reviewing who qualifies to act as a company director, since undischarged bankrupts and those subject to disqualification orders are prohibited from acting.

What Are the Seven Duties of a Company Director?

The seven general duties are set out in sections 171 to 177 of the Companies Act 2006. All seven duties are owed to the company itself, not directly to shareholders, employees, or creditors. It is the company that has the right to enforce them, either through the board or through a derivative claim brought by a shareholder with court permission. A director who acts against the wishes of a majority shareholder may still be meeting their duties in full, provided the company as a whole benefits. A limited company exists as a separate legal person, distinct from those who own or run it. 

The table below summarises each statutory duty and its section reference.

Duty (Companies Act 2006)	What it means
Act within powers (s.171)	Directors must follow the company’s constitution and use their powers only for the purposes for which they were given. Acting outside those powers, or using them to pursue a personal aim, breaches this duty.
Promote the success of the company (s.172)	Directors must act in good faith in the way they believe will best promote the company’s long-term success for the benefit of its members, taking into account employees, suppliers, the environment, and the company’s reputation.
Exercise independent judgement (s.173)	Directors must reach their own decisions and not simply follow instructions from a shareholder or investor. They may rely on professional advice, but must apply their own judgement to it.
Exercise reasonable care, skill and diligence (s.174)	Directors are held to the standard of a reasonably diligent person in their role. Where they hold a professional qualification, the bar is raised accordingly. Ignorance of the company’s affairs is not a defence.
Avoid conflicts of interest (s.175)	Directors must avoid situations where their personal interests could conflict with those of the company, including business opportunities that arise through their position. The obligation can continue after they leave office.
Not accept benefits from third parties (s.176)	Directors must not accept gifts, hospitality, or other benefits given because of their position if those benefits could reasonably be seen as creating a conflict of interest.
Declare interest in proposed transaction (s.177)	Before the company enters a transaction in which a director has a personal interest, that director must disclose the nature and extent of their interest to the other directors. Failure to do so can result in criminal as well as civil liability.

Act Within Powers as a Company Director

Every company operates under a set of rules that govern what it can do and how decisions must be made. These rules are contained in the company’s articles of association, which are filed with Companies House when the company is formed. As a director, you must stay within those rules at all times. 

Think of the articles of association as the company’s rulebook. They set out what the board of directors is allowed to do, and on what basis. If you take an action that falls outside those rules, or use a power given to you by the company for a different purpose than it was intended, you may be in breach of your duty, even if you genuinely believed you were doing the right thing. Intention alone does not protect you.

Promote the Success of the Company as a Company Director

This duty is widely considered the most important of the seven. Put simply, you must make decisions that you genuinely believe are in the best interests of the company and its shareholders as a whole. You must act in good faith, meaning honestly and with the company’s long-term well-being in mind, not your own.

The Companies Act 2006 spells out the factors you must actively consider when making decisions as a director:

• the likely long-term consequences of the decision, not just the immediate result;
• the interests of the company’s employees;
• the company’s relationships with its suppliers and customers; and
• the impact of the company’s activities on the community and the environment.

Exercise Independent Judgment as a Company Director

As a director, your decisions must be your own. You cannot simply do what a major shareholder tells you to do, or follow the lead of another director, without applying your own mind to the issue. The law expects you to think for yourself.

This does not mean you cannot take advice. You are actively encouraged to consult lawyers, accountants, and other specialists. The point is that after receiving that advice, you must form your own view and make your own decision. If you simply rubber-stamp what someone else has decided, you may be in breach of this duty, even if the outcome was perfectly reasonable.

Exercise Reasonable Care, Skill and Diligence

You do not need to be an expert in every aspect of running a business to be a director. But you are expected to reach a basic standard of competence, attention, and effort in carrying out a director’s role. The law sets this as the standard you would expect from a reasonably diligent person doing the same job.

Practically, this means you should attend board meetings, read the financial information provided to you, and take part in major decisions. A director who consistently ignores information, misses meetings, or leaves all decisions to one other person cannot claim ignorance as a defence if something goes wrong.

Avoid Conflicts of Interest When Acting in a Director’s Role

A conflict of interest arises whenever your personal interests, or the interests of someone close to you, could pull in a different direction from the interests of the company. As a director, you must avoid these situations, or at the very least disclose them and get proper authorisation from the board before proceeding.

This obligation does not end when you resign. If you leave the company and then pursue an opportunity you first learned about while you were a director, the duty may still apply. The courts have taken a strict approach here. Where a conflict is neither disclosed nor authorised, the company can require you to hand over any profit you made.

Not Accept Benefits From Third Parties When Acting in a Director’s Role

You must not accept gifts, payments, hospitality, or any other benefit from someone outside the company if that benefit is being offered because of your position as a director. The concern is that such benefits could, consciously or not, influence the decisions you make on behalf of the company.

Declare an Interest in Proposed Transactions

If the company is about to enter into a contract or arrangement and you have a personal interest in that transaction, you must tell the other directors before the company commits. This applies whether the interest is direct, such as being a party to the contract yourself, or indirect, such as a family member or business associate standing to benefit.

The declaration must cover the nature of your interest and its extent. It can be made at a board meeting, in a written notice, or by giving a general notice that covers a category of transactions in advance. What it cannot be is silent. If you fail to declare and the company later suffers as a result, you face both civil and criminal exposure.

Consequences of Breaching the Duties of a Director

The consequences of breach range from civil liability to disqualification and criminal prosecution. The Insolvency Service investigates director conduct following every formal insolvency, and disqualification orders last between two and fifteen years. A director subject to such an order cannot act as a director, or take part in the management of any company, without court permission.

Personal liability for company debts can follow from wrongful or fraudulent trading. Non-executive directors are not exempt: appointment carries responsibility regardless of the level of day-to-day involvement. A director who takes no part in management during a period of financial difficulty remains liable for the consequences of decisions made without their input.

Best Practice for Compliance With the Duties of a Director

To ensure you remain in compliance with your director’s duties, we recommend that you:

• Read and understand the articles of association on appointment, and return to them when significant decisions are being made
• Keep board minutes of significant decisions, recording the reasoning. A contemporaneous note carries real evidential weight if duties are later called into question
• Declare personal interests promptly at the earliest opportunity, rather than waiting to assess relevance
• Watch the company’s financial position actively, and take independent advice early if signs of financial stress emerge
• Verify your identity with Companies House if you have not already done so. Acting without verification is an offence under the “Economic Crime and Corporate Transparency Act 2023.

Final Words

The duties of a director in the UK are a genuine legal commitment. The Companies Act 2006 gives those duties clear statutory expression, and courts enforce them seriously. Recent changes, including mandatory identity verification introduced in late 2025, show that the regulatory framework around the director’s role continues to develop. Anyone taking on a directorship, should treat these obligations seriously.
