Directors run the company. In doing so they owe duties to the company itself — not to shareholders individually, not to the person who appointed them, and not to their own commercial interests.
The Companies Act 2006 codified seven general duties, replacing much of the old case law with statutory language while preserving its interpretation. Alongside them sit filing duties, health and safety responsibilities, insolvency-related obligations and a growing set of sector-specific rules.
This guide summarises what directors of UK private companies must do, where personal liability arises, and how to evidence good decision-making.
The seven statutory duties
Sections 171 to 177 require a director to: act within powers conferred by the constitution; promote the success of the company for the benefit of members as a whole; exercise independent judgement; exercise reasonable care, skill and diligence; avoid conflicts of interest; not accept benefits from third parties; and declare any interest in a proposed transaction.
The duty to promote success under section 172 requires directors to have regard to long-term consequences, employee interests, relationships with suppliers and customers, community and environmental impact, reputation, and fairness between members. It is a decision-making framework as much as a standard, and minutes should show it was applied.
Care, skill and diligence in practice
The standard is objective and subjective: the care, skill and diligence expected of a reasonably diligent person with the general knowledge and experience reasonably expected of someone in that role, and with the actual knowledge and experience the director in fact has. A qualified accountant on the board is held to a higher financial standard than a lay director.
In practice this means attending meetings, reading the papers, asking questions, seeking professional advice on matters outside your competence, and not simply deferring to a dominant founder or executive. Delegation is permitted; abdication is not.
Conflicts of interest and related-party transactions
Directors must avoid situations where their personal interests conflict, or may conflict, with the company's. In private companies, unconflicted directors can authorise a conflict if the articles permit — check the articles, as model articles include this power for private companies.
Interests in proposed transactions must be declared before the transaction is entered into; interests in existing transactions must also be declared. Certain transactions need shareholder approval, including substantial property transactions with a director, loans to directors and long-term service contracts exceeding two years. Record declarations in the minutes.
Filing and administrative responsibilities
Directors are responsible for keeping adequate accounting records, preparing and filing annual accounts, filing the confirmation statement, maintaining statutory registers, and keeping the register of people with significant control accurate. Late filing brings automatic penalties and, in persistent cases, disqualification proceedings.
Reforms under the Economic Crime and Corporate Transparency Act 2023 introduced identity verification for directors and people with significant control, along with stronger Companies House powers. Directors should ensure the company's records and their own verification status are current.
Insolvency, wrongful trading and personal liability
When a company is, or is likely to become, insolvent, directors' duties shift towards the interests of creditors. Continuing to trade when there was no reasonable prospect of avoiding insolvent liquidation can lead to a wrongful trading contribution order under section 214 of the Insolvency Act 1986.
Other personal exposures include fraudulent trading, misfeasance, preferences and transactions at an undervalue, personal guarantees given to lenders and landlords, and unpaid PAYE or VAT in defined circumstances. If solvency is in doubt, take insolvency advice immediately, meet frequently, and minute the reasoning behind every decision to continue.
Evidencing good governance
Directors are judged on process as well as outcome. Regular board meetings with agendas, circulated papers, recorded attendance and substantive minutes are the primary evidence that duties were discharged. Minutes should record the factors considered — including section 172 factors — not merely the resolution passed.
Consider directors' and officers' liability insurance, and check whether the articles include an indemnity to the extent permitted by law. Neither protects against fraud or dishonesty, but both matter where an honest decision is later challenged.
Key points
- Duties are owed to the company, not to the shareholder who appointed you.
- Section 172 requires wider factors to be considered — record them in minutes.
- The care and skill standard rises with your actual expertise.
- Declare interests before entering into a transaction, and minute the declaration.
- Near insolvency, duties shift to creditors and wrongful trading risk arises.
- Good minutes are the primary evidence that duties were properly discharged.
Frequently asked questions
- Can a director be personally liable for company debts?
- Generally no, because the company is a separate legal person. Exceptions include personal guarantees, wrongful or fraudulent trading, misfeasance and certain tax liabilities where HMRC issues a personal liability notice.
- What is a shadow director?
- Someone in accordance with whose directions or instructions the directors are accustomed to act, without being formally appointed. Shadow directors can be subject to many of the same duties and liabilities, which matters for investors and major shareholders who direct board behaviour.
- Do non-executive directors owe the same duties?
- Yes, the statutory duties apply equally. The care and skill expected reflects the role and their actual knowledge, but non-executives cannot rely on limited involvement as a defence to inadequate oversight.
- How do I resign as a director?
- Give notice in accordance with the articles and any service agreement, and file form TM01 at Companies House. Resignation does not remove liability for acts while in office, and resigning to avoid dealing with insolvency can itself be scrutinised.
