Independent Director vs Non-Executive Director: What's the Difference?

Ask a NED to define "independent director" off the cuff, and most will reach for the same word: outsider. That is close, but the UK Corporate Governance Code is more exacting than that, and the gap between the loose definition and the formal one is where boards get caught out.

A non-executive director (NED) is any board member who is not part of day-to-day management. An independent NED is a narrower category: one the board has tested against a specific list of relationships and circumstances — set out in Provision 10 of the UK Corporate Governance Code — and found free of anything likely to compromise their judgement. Every independent director is a non-executive director. Not every non-executive director is independent.

Key takeaways

• "Non-executive" describes the job; "independent" describes a separate test. A NED who fails the independence test is still a NED — the board simply cannot count them towards its independence requirement without explaining why.
• Provision 10 of the UK Corporate Governance Code lists seven circumstances likely to compromise independence, including recent employment, material business ties, extra remuneration, and tenure beyond nine years.
• At least half the board, excluding the chair, should be independent NEDs, under Provision 11 — and the chair should have been independent on appointment.
• 4% of NEDs and 8% of non-executive chairs had exceeded the nine-year term limit as at 30 April 2025, according to the Spencer Stuart UK Board Index, 2025.
• Departures from at least one Code Provision fell from 73 companies in 2022 to 28 in 2024, with non-compliance against both core independence provisions — chair independence and board composition — falling over the same period, according to the Financial Reporting Council's Review of Corporate Governance Reporting, 2024.

What is a non-executive director?

A non-executive director is a board member who takes no part in running the company day to day. They sit alongside the executive directors — the chief executive, the finance director, and others who manage the business — but they are not employees, and their job is oversight, not operations. Every NED, independent or not, owes the same statutory duties as an executive director: the seven general duties set out in sections 170 to 177 of the Companies Act 2006 apply to every director, with no carve-out for non-executives.¹

That is the whole of what "non-executive" tells you. It says nothing about whether the person is free of ties to the company or its management. That is a separate, more specific question — and it is the one "independent" answers.

What is an independent director?

An independent director — in UK terms, an independent non-executive director, or iNED — is a NED the board has assessed against a defined test and judged free of relationships likely to compromise, or appear to compromise, their judgement. The test is Provision 10 of the UK Corporate Governance Code, published by the Financial Reporting Council (FRC), and the board must state in its annual report which NEDs it considers independent.²

The Code is explicit about what independence protects. Under Principle G, the board should include "an appropriate combination of executive and non-executive (and, in particular, independent non-executive) directors, such that no one individual or small group of individuals dominates the board's decision-making."² Independence is the safeguard against a board that agrees with itself too easily.

What circumstances can compromise a NED's independence?

Provision 10 lists seven circumstances the board should treat as likely to impair independence, "but are not limited to." A NED who meets one of these is not automatically excluded — but the board must explain, in the annual report, why it still considers them independent. According to the Code, the board should consider whether a director:²

• is or has been an employee of the company or group within the last five years
• has, or has had within the last three years, a material business relationship with the company
• has received or receives additional remuneration apart from a director's fee, participates in a share option or performance-related pay scheme, or is a member of the company's pension scheme
• has close family ties with any of the company's advisers, directors or senior employees
• holds cross-directorships or has significant links with other directors through other companies
• represents a significant shareholder
• has served on the board for more than nine years from first appointment

That last point is the one most experienced NEDs recognise from their own portfolios. Long service builds insight, but the Code treats it as a factor that can erode the outsider's distance a board needs — which is why some long-serving, well-regarded NEDs still appear in annual reports with an explanation attached rather than a clean "independent" label.

How many independent NEDs does a board need?

Provision 11 sets the number: at least half the board, excluding the chair, should be non-executive directors the board considers independent.² Provision 9 adds that the chair should themselves have been independent on appointment, judged against the same Provision 10 test — though the chair is not counted towards the Provision 11 half.² Once appointed, the board also names a senior independent director from among the independent NEDs, under Provision 12, to provide a sounding board for the chair and serve as an intermediary for the other directors and shareholders.²

Boards report against all of this on a "comply or explain" basis — the Code "does not set out a rigid set of rules; instead, it offers flexibility through 'comply or explain' reporting against the Provisions."² Departures are allowed, but they must be disclosed and justified, not left silent.

Compliance with the Code's independence provisions has been improving. Companies departing from at least one Code Provision, out of a sample of 100 FTSE 100, FTSE 250 and Small Cap annual reports, fell from 73 in 2022 to 28 in 2024 — and the FRC specifically records "a decline in non-compliance with other provisions, such as Provisions 9 (chair independence), 11 (board composition)" over the same period, according to the FRC's Review of Corporate Governance Reporting, 2024.³

Executive director vs NED vs independent NED, compared

Does tenure actually erode independence in practice?

The nine-year threshold in Provision 10 is a guideline, not a cliff edge — but the data suggests boards mostly manage it before it becomes one. Among NEDs currently in post, the average tenure is 4.3 years, and only 5% have served more than nine years; 4% of NEDs and 8% of non-executive chairs specifically had exceeded the nine-year term limit as at 30 April 2025, according to the Spencer Stuart UK Board Index, 2025.⁴

Most NEDs also carry commitments elsewhere: 62% hold at least one additional listed-company board role, according to the same Spencer Stuart index.⁴ That is not itself an independence concern under Provision 10 — cross-directorships only bite when they create "significant links with other directors" — but it is part of why boards increasingly want independence understood as more than a checklist.

That broader view has an institutional advocate. A January 2026 review by the Institute of Directors argues independence should not be read too narrowly: "NED independence should be conceived less narrowly, focusing on independence of mind, cognitive diversity as well as criteria avoiding potential conflicts of interest," while explicitly stopping short of proposing changes to the Code's own criteria.⁵ Baroness Evans of Bowes Park, who chaired the review's commission, framed the wider shift as a move "from a model of periodic oversight to one of active, informed, and adaptive stewardship," according to the IoD, 2026.⁵ The formal test in Provision 10 sets the floor. What boards are increasingly asking of independent NEDs sits above it.

Is "independent director" a UK or a US term?

Both, but they map slightly differently. In UK governance, "independent director" and "independent non-executive director" are used interchangeably, and both point to the Provision 10 test. In the US, "independent director" is the formal term under NYSE and Nasdaq listing rules,⁶ and the more general term "outside director" is closer to the UK's plain "non-executive director" — a board member from outside management, independent status not implied either way.⁷ The practical lesson carries across both systems: when a board, a headhunter or a listing rule calls someone "independent," it is describing a specific, disclosable test — not a synonym for "non-executive."

In summary

Non-executive and independent are not the same claim. A NED is anyone on the board who is not part of management; an independent NED is a NED the board has tested against Provision 10 of the UK Corporate Governance Code and disclosed as free from the relationships likely to compromise their judgement — recent employment, material business ties, extra pay, family connections, cross-directorships, major shareholdings, or more than nine years' tenure. Get the two terms straight, and the rest of the Code's board-composition rules — half the board independent, an independent chair on appointment, a senior independent director — follow naturally.
