Duties of Directors under Companies Act 2013.
The statutory duties read as a list; they operate as the standard against which a director’s past conduct is measured.
A founder-director who has run the company on instinct and good faith learns — usually during a dispute, an investor diligence, or an audit — that the Companies Act 2013 codifies precisely what a director owes the company, and that the codification is the yardstick a court or regulator applies to decisions already taken. The duties were always binding; they simply became visible at the moment they were tested.
Section 166 converts what was once judge-made fiduciary doctrine into express statutory duties, and they sit at the centre of the entity’s Operating System — the component that governs how decisions are made and how accountability flows. This page sets out what those duties require in practice and where falling short of them becomes exposure.
How We Read the Statutory Duties.
The firm does not treat Section 166 as a recital to be acknowledged once and filed. The duties are the standard of conduct against which every board decision is judged after the fact, and the difference between a defensible decision and a breach almost always sits in the record — whether the director can show good faith, due care, and the absence of an undisclosed conflict.
We read the duties as the lens through which board process should be designed, so that observance is evidenced in the ordinary course rather than reconstructed under challenge. The objective is a board whose conduct is provable, not merely well-intentioned.
- Good-faith standard The duty under Section 166 to act in good faith to promote the company’s objects and the interests of its members, employees, and wider stakeholders.
- Care and diligence The duty to exercise independent judgement and reasonable care, skill, and diligence — the standard against which an alleged failure of oversight is tested.
- Conflict discipline The duty to avoid conflicting interests and not to pursue undue gain, which underpins the disclosure and related-party regime.
- Evidenced observance Whether the board’s minutes, disclosures, and decision records actually demonstrate the duties were discharged rather than merely asserting it.
From a List of Duties to a Standard of Conduct.
The duties are easy to recite and hard to evidence. The decision that matters in practice is how the board is run so that observance is provable — set out below.
What Section 166 Actually Requires of a Director
Section 166 codifies the core duties: to act within the company’s constitution; to act in good faith to promote its objects and stakeholder interests; to exercise due and reasonable care, skill, and independent judgement; to avoid conflicts of interest; not to achieve undue gain; and not to assign the office. Stated this way they read as principles. Their force is that each one is a measurable standard a director can be shown to have fallen below.
The duty of care is the one most often misread. It does not require a director to be right; it requires them to engage — to attend, read the board papers, and form an independent view rather than deferring reflexively to a dominant promoter or the management team. A director who is passive has not discharged the duty by avoiding bad faith alone, because the standard is care and diligence, not honesty in isolation.
The conflict duties are where statutory duty meets the related-party regime. A director interested in a transaction must disclose under Section 184 and stand apart from its approval; a failure here is simultaneously a breach of duty and, frequently, the foundation of a transaction challenge. The same failure of duty, left unaddressed across years of filings, is also a common route to director disqualification — the point at which the consequence shifts from the company to the individual.
The practical consequence is that the duties are managed through process, not awareness. A board that records its deliberations, captures disclosures, and shows that directors applied independent judgement has built the evidence the standard requires; a board running on consensus and thin minutes has not, however honestly it acted.
What the Duties Set in Motion.
How the statutory duties are observed shapes the exposure that follows from every board decision.
Liability trigger
A breach of the Section 166 duties is the most common gateway to personal liability and, in serious cases, to disqualification — the duties define the conduct the later sanctions punish.
Board process
Because the duties are evidenced through the record, they govern how meetings are run, how disclosures are captured, and how minutes are written.
Defensibility
A board that can show duties were discharged in the ordinary course answers a challenge from a position of record rather than reconstruction.
