A non-executive director (NED) is a board member who does not manage the business day to day. Their role is to give independent oversight in four areas: strategy, scrutiny of performance, risk and people. In the UK they have the same legal duties as executive directors, and the Corporate Governance Code says at least half the board, excluding the chair, should be independent NEDs.
The four roles of a non-executive director
The classic framework, from the Higgs Review (2003) and reflected in today's UK Corporate Governance Code, groups the role into four areas:
| Role | What NEDs do | SBL angle |
|---|---|---|
| Strategy | Contribute to and constructively challenge the strategy proposed by executives | Do the NEDs have the skills and information to challenge the CEO's plan? |
| Scrutiny | Monitor executive performance against agreed goals; check financial information is accurate | Are results being reported honestly? Is anyone holding management to account? |
| Risk | Satisfy themselves that internal controls and risk management are robust | Does the audit committee work? Are risks escalated to the board? |
| People | Appoint and remove executives, plan succession, set executive pay | Are pay and appointments independent of the executives who benefit? |
What the UK Corporate Governance Code 2024 requires
The Code applies to premium listed companies for financial years beginning on or after 1 January 2025 (FRC, UK Corporate Governance Code 2024). The key NED provisions:
| Provision | Requirement |
|---|---|
| Principle H | NEDs should have enough time for their duties, and should provide constructive challenge, strategic guidance and specialist advice, and hold management to account. |
| Provision 10 | The board identifies which NEDs are independent. Independence may be impaired if, for example, the director was an employee in the last five years, has a material business relationship, receives extra pay or a pension, has close family ties, holds cross-directorships, represents a significant shareholder or has served more than nine years. |
| Provision 11 | At least half the board, excluding the chair, should be independent NEDs. |
| Provision 12 | One independent NED is appointed senior independent director (SID): a sounding board for the chair and a route for shareholders and directors. NEDs, led by the SID, appraise the chair at least once a year. |
| Provision 13 | The chair should hold meetings with the NEDs without the executives present. |
| Provisions 24 and 32 | The audit and remuneration committees should be made up of independent NEDs, at least three members (two for smaller companies). |
| Provision 34 | NED pay should not include share options or other performance-related elements. |
Executive vs non-executive directors
| Executive director | Non-executive director | |
|---|---|---|
| Role | Runs the business day to day | Oversees and challenges from outside management |
| Time | Full-time employee | Part-time, often a few days a month |
| Pay | Salary plus bonus and share schemes | Fixed fee, no performance-related pay |
| Independence | Not independent | Usually expected to be independent |
| Legal duties | Full director duties | The same full director duties |
How NEDs come up in the SBL exam
Governance is syllabus area B, and SBL scenarios often feature a weak or captured board. Typical tasks ask you to assess board effectiveness, advise on the role of NEDs, or recommend changes after a governance failure. To score well:
- Spot the red flags in the case: too few independent NEDs, a CEO who is also chair, a NED who used to be finance director, long tenure, NEDs with no relevant expertise, or committees chaired by executives.
- Link each flag to a consequence: for example, no independent audit committee means weaker scrutiny of financial reporting.
- Recommend specific fixes: recruit independent NEDs with the missing skills, appoint a SID, rebalance committees, introduce board evaluation.
- Consider the organisation type. The Code applies to listed companies. For a charity, public body or family firm, explain which principles still make sense and why.
Board committees run by NEDs
| Committee | Members | Main job |
|---|---|---|
| Audit committee | Independent NEDs, at least three (two for smaller companies); the board chair should not be a member | Oversees financial reporting, internal control, internal audit and the external auditor |
| Remuneration committee | Independent NEDs, at least three (two for smaller companies) | Sets executive pay policy and individual pay for executives and the chair |
| Nomination committee | A majority of independent NEDs | Leads board appointments, succession planning and board diversity |
Unitary vs two-tier boards
The UK uses a unitary board, where executives and NEDs sit together and share responsibility. Germany and some other countries use a two-tier board: a management board of executives and a separate supervisory board of non-executives and often employee representatives. SBL scenarios sometimes use a two-tier structure, as in the Historic Places case, so be ready to compare them: unitary boards share information better; two-tier boards separate monitoring more clearly from management.
Agency theory: why NEDs matter
Agency theory explains the governance problem NEDs address. Shareholders (principals) own the company but directors and managers (agents) run it, and agents may act in their own interests, for example through excessive pay or risky empire building. Independent NEDs reduce these agency costs by monitoring executives on the owners' behalf.
Worked example: a heritage charity
Historic Places (March 2025 pre-seen) has a Board of Trustees and an Executive Board. Trustees play a role similar to NEDs. A strong answer might note that members can only vote on some trustee roles and that nominations are controlled by committees, raising questions about independence and accountability. Recommendations could include independent trustees with commercial and digital skills, an audit committee of independent trustees, and a regular, externally facilitated board evaluation.
Advantages and criticisms of NEDs
Advantages
- Independent challenge reduces the risk of reckless or self-serving decisions
- Bring outside experience and contacts
- Reassure investors, lenders and regulators
- Make pay and appointments fairer
Criticisms
- Limited time and information; they depend on executives for data
- Can become too close to management over time
- Hard to find people who are both independent and expert
- Same legal liability as executives for part-time pay can deter good candidates
FAQs
What is a non-executive director?
A non-executive director (NED) is a board member who is not part of the executive management team. They give independent oversight, constructive challenge and strategic advice, usually part-time, without running the business day to day.
What is the role of non-executive directors?
The four classic roles are strategy (contributing to and challenging strategy), scrutiny (holding executives to account for performance), risk (making sure controls and risk management are robust) and people (appointing, removing and setting the pay of executives).
How many non-executive directors should a UK listed company have?
Under the UK Corporate Governance Code 2024, at least half the board, excluding the chair, should be independent non-executive directors.
Do non-executive directors have the same legal duties as executive directors?
Yes. In UK company law there is no separate category of NED: all directors share the same statutory duties, including promoting the success of the company and exercising independent judgement and reasonable care, skill and diligence.
Can non-executive directors receive share options?
The UK Corporate Governance Code says NED remuneration should not include share options or other performance-related elements, because that could compromise their independence.
