What is Corporate Governance

By Adrian Lawrence FCA, founder of NED Capital · Part of the Board Governance Hub

Few phrases are used as loosely as “corporate governance”. It is invoked in annual reports, regulatory notices and boardroom debates alike, often without a shared understanding of what it actually means or how it works in a specific national context. This guide sets out a clear definition, then focuses on how governance operates in the UK in particular — because the framework here, built around the UK Corporate Governance Code and the Companies Act, differs in important ways from the systems found elsewhere. It is written for company owners, executives, aspiring and serving non-executive directors, and anyone who needs to understand not just the theory of governance but how a well-governed British company is actually run.

Defining Corporate Governance

At its simplest, corporate governance is the system by which companies are directed and controlled — the definition made famous by the Cadbury Report of 1992, which remains the foundation of modern UK governance thinking. It encompasses the relationships between a company’s management, its board, its shareholders and its wider stakeholders, and the framework through which the company’s objectives are set and pursued. Governance is not the same as management. Management runs the business day to day; governance is concerned with how the company is overseen and held to account — who makes which decisions, how power is balanced, how risks are controlled, and how those in charge answer for the results. A useful way to think about it is that governance exists to address a basic problem that arises whenever ownership and control are separated: the people who run a company are not usually the people who own it, and their interests do not always align. The shareholders who provide the capital need assurance that the executives running the business are doing so competently, honestly and in the company’s long-term interests rather than their own. Corporate governance is the set of structures and disciplines — an independent board, transparent reporting, external audit, defined accountability — that provides that assurance. Its ultimate aim is not box-ticking compliance but something more fundamental: a company that is well-run, well-controlled and worthy of the trust placed in it by its investors, its employees and the public.

The UK Framework: The Corporate Governance Code and “Comply or Explain”

The distinctive feature of UK corporate governance is that, for listed companies, it is shaped less by prescriptive law than by a principles-based code operating on a “comply or explain” basis. The UK Corporate Governance Code, maintained by the Financial Reporting Council, sets out the principles and provisions expected of premium-listed companies — covering board leadership and effectiveness, the division of responsibilities, composition and succession, audit and risk, and remuneration. Its lineage runs from the Cadbury Report (1992), through the Greenbury and Hampel reports and the combined codes that followed, to the Higgs Review (2003), which strengthened the role and independence of non-executive directors, and on to the Code in its current form. Crucially, the Code is not statute. Rather than requiring rigid compliance, it asks companies either to comply with its provisions or to explain, clearly and specifically, why they have chosen a different approach that still achieves good governance. This “comply or explain” mechanism is the defining characteristic of the UK model and is often contrasted with the more rules-based, statutory approach seen in some other jurisdictions. Its logic is that good governance is not one-size-fits-all: a well-run company may have sound reasons for departing from a particular provision, and shareholders are better served by a considered explanation they can judge for themselves than by mechanical box-ticking. The system relies, therefore, on the quality of company disclosure and on shareholders actually engaging with it — holding boards to account for the explanations they give. It is a framework built on judgment and transparency rather than compulsion, and it places a significant premium on boards that take the substance of governance seriously rather than merely its form. The way the Code bears specifically on non-executives is explored in how the UK Corporate Governance Code impacts non-executive directors.

Directors’ Statutory Duties Under the Companies Act 2006

Alongside the Code sits the hard law that applies to every UK company, listed or not: the statutory duties owed by directors under the Companies Act 2006. Where the Code is principles-based and applies chiefly to listed companies, these duties are legal obligations binding on all directors of all companies. Among the most important is the duty under section 172 to act in the way a director considers, in good faith, would be most likely to promote the success of the company for the benefit of its members as a whole — while having regard to a range of wider factors, including the likely long-term consequences of decisions, the interests of employees, relationships with suppliers and customers, the impact on the community and environment, and the desirability of maintaining a reputation for high standards of business conduct. The Act also codifies duties to act within powers, to exercise independent judgment, to exercise reasonable care, skill and diligence, to avoid conflicts of interest, not to accept benefits from third parties, and to declare interests in proposed transactions. These duties matter greatly for understanding governance, because they apply equally to executive and non-executive directors alike: a non-executive is a full director in law and carries the same statutory responsibilities and potential personal liability as any other board member. This is a point often misunderstood, and it is set out in detail in the legal duties of a non-executive director in the UK. Together, the statutory duties and the Code form the two pillars of UK governance — the law setting the baseline obligations that bind every director, and the Code raising the bar for listed companies through principles and disclosure.

The Key Principles of Good Governance

Beneath the specific rules and codes, corporate governance rests on a handful of enduring principles that recur across every framework. Accountability is the first: management must be answerable to the board, and the board in turn to the shareholders, with clear lines of responsibility so that decisions can be traced and those who make them can be held to account. Transparency is the second: the timely, accurate and honest disclosure of material information — financial and non-financial — so that shareholders and stakeholders can make informed judgments and hold the company to account. Fairness is the third: the equitable treatment of all shareholders, including minority investors, and proper regard for the legitimate interests of other stakeholders. Responsibility is the fourth: recognition that a company’s obligations extend beyond its immediate financial performance to its people, its conduct and its wider impact — increasingly expressed today through environmental, social and governance considerations. To these four classic principles two more are often added in a modern context. Effective risk management — the identification, assessment and control of the risks that could threaten the company’s objectives — has become a central governance responsibility of the board, explored further in the role of non-executive directors in corporate risk management. And board effectiveness — a board of the right size, composition, independence and skill to provide genuine oversight — underpins all the rest, since none of the other principles can be delivered by a board that is poorly constituted or insufficiently independent. These principles are not a checklist to be completed but a set of standards to be lived; a company can satisfy every technical provision of a code and still be badly governed if it does not take them seriously in substance.

The Board and the Central Role of the Non-Executive Director

If governance is the system, the board of directors is the mechanism through which it operates. The board sits at the apex of a company’s governance structure, collectively responsible for its long-term success: setting strategy and values, overseeing management, ensuring that risks are understood and controlled, and answering to shareholders. An effective board depends heavily on its balance — in particular, on the presence of capable independent non-executive directors alongside the executives. The non-executive director’s role is distinct and, for governance, indispensable. NEDs are not involved in running the business day to day; their purpose is to bring independent, objective judgment to the boardroom — to constructively challenge and help develop strategy, to scrutinise the performance of management, to satisfy themselves on the integrity of financial information, and to play the leading role on the audit, remuneration and nomination committees where independence matters most. Their value lies precisely in their independence: because they are not part of the executive team, they can ask the difficult questions, test the assumptions and, where necessary, hold the line in a way that those enmeshed in day-to-day management cannot. This is why the UK framework places such weight on genuine independence — a subject examined in what makes a board truly independent in practice — and why the composition of the board, and the calibre of the non-executives on it, is so often the difference between governance that works and governance that merely appears to. It is also worth noting that good governance is not the preserve of large listed companies: smaller and private businesses are not bound by the Code, but its principles — and the Wates Corporate Governance Principles developed specifically for large private companies — apply in spirit, and the independent challenge a NED brings is often even more valuable in a growing company than in a mature listed one. The board’s composition, structure and independence are explored further in our guide to board structure, composition and independence.

Why Corporate Governance Matters

The case for good governance is ultimately practical, not merely ethical. Companies with strong governance tend to command greater trust from investors, which translates into easier access to capital and, often, a lower cost of it; investors will pay more, and demand less of a risk premium, for a business they believe is well-run and well-controlled. Good governance also protects against the failures that destroy value and reputation: the great corporate collapses, from the scandals that prompted the Cadbury Report to those that have followed since, have almost invariably been failures of governance as much as of commerce — boards that did not challenge, risks that were not controlled, information that was not disclosed. Beyond avoiding disaster, sound governance supports better decision-making, because a properly constituted board brings independent scrutiny and diverse perspective to bear on strategy; it strengthens a company’s reputation and licence to operate; and it aligns the business with the long-term interests of its members rather than short-term expedience. For all these reasons, governance is not a compliance overhead to be minimised but a genuine source of resilience and competitive strength. The historical global context — the different governance models found in the shareholder-focused Anglo-American world, the stakeholder-oriented systems of continental Europe, and elsewhere — reflects different answers to the same underlying question of how companies should be held to account; but for a UK company, the answer is found in the combination of the Companies Act and the Corporate Governance Code, brought to life by an effective, independent-minded board. Building that board is where governance moves from theory into practice.
