The Pros and Cons of Hiring Interim NEDs

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

When a board faces a sudden gap, a period of upheaval or a challenge calling for expertise it does not currently have, an interim non-executive director can look like an appealing answer — and often it is. But like any board decision it carries advantages and drawbacks that deserve honest examination, and it also carries a couple of definitional traps that can lead a board to expect the wrong thing. This article sets out what an interim NED actually is, the genuine pros, the genuine cons, and how to decide well.

What an Interim NED Actually Is — and Isn’t

Before weighing pros and cons, it is worth being precise about the role, because two common confusions lead boards astray. An interim non-executive director is someone appointed to the board for a temporary, defined period — to cover a gap left by a departure, to add specific expertise while the board navigates a transition, merger or crisis, or to provide independent input for a particular situation — on the understanding that the appointment is not permanent. The first confusion is between interim and fractional. These are not the same thing: an interim NED is temporary, appointed for a fixed period after which the role ends or converts; a fractional NED is ongoing but part-time, an enduring role delivered across fewer days. A board wanting flexible, continuing input may actually want a fractional arrangement, while one covering a defined gap wants an interim; the distinction is drawn out in fractional executive vs NED: which does your business need. The second and more important confusion is between an interim NED and an interim executive. An interim executive — a turnaround director, a temporary managing director — is brought in to run things, to take hold of the operation and drive change directly. An interim NED is not that. Temporary though the appointment is, the role remains a non-executive one: the interim NED oversees, challenges and guides, but does not take the wheel and run the business, even in a crisis where the temptation to do so is strongest. This matters because a board that hires an interim NED expecting hands-on executive delivery has misunderstood what it is buying, and an interim NED who drifts into executive action has misunderstood the role. It is also worth stressing that an interim NED is a full director in every legal sense: the same fiduciary duties, the same personal liability, and the same independence as a permanent non-executive. Temporary status changes the duration, not the duties.

The Pros: Speed, Targeted Expertise and Fresh Objectivity

With the role properly understood, the advantages of an interim appointment are real and often compelling. The first is speed. When a board loses a member unexpectedly, or a situation blows up that demands experienced oversight now rather than after a months-long search, an interim NED can be in place quickly — providing competent, independent input at exactly the moment the board most needs it, and buying time to conduct a proper permanent search without leaving a governance gap in the meantime. The second is targeted expertise. Interim appointments are often made precisely because a board faces a specific challenge — a transaction, a regulatory problem, a turnaround, a technology question — and needs someone who has navigated that particular situation before. An interim can bring exactly that expertise for exactly as long as it is needed, without committing the board to a permanent seat filled on the basis of a temporary need. The third is objectivity. Because the interim NED arrives with no history in the business, no allegiances and no stake in past decisions, they can bring an unusually clear-eyed, independent perspective — asking the obvious questions a settled board may have stopped asking, and challenging assumptions that insiders have come to take for granted. In a transition or crisis, that detachment can be genuinely valuable, and it is closely related to the oversight strength a board draws on during periods of upheaval, discussed in how NEDs strengthen oversight during leadership transitions. For the right situation — an urgent gap, a defined challenge, a need for fresh independent eyes — these advantages make an interim appointment a sensible and sometimes ideal choice.

The Cons: Shallower Roots and the Succession Trap

The drawbacks are equally real, and a board should weigh them honestly rather than being seduced by the convenience of a quick fix. The most inherent is shallowness of knowledge and relationships. A permanent non-executive builds, over years, a deep understanding of the company’s history, culture, people and context, and the trusted relationships that make challenge effective; an interim, by definition, has far less time to develop either. They face a steep learning curve, may never acquire the institutional knowledge that informs the best board judgment, and may find it harder to build the rapport that lets a non-executive challenge robustly without causing rupture. Related to this is the risk of shallower engagement: an interim, knowing the role is temporary, may — not always, but sometimes — invest less of themselves in the company’s long-term future than a permanent member whose reputation is tied to it. And interim expertise can command a premium, so the arrangement is not always the economy it appears. But the drawback that matters most is subtler and more strategic: the risk of using interim appointments as a substitute for proper succession planning. It is easy for a board to reach repeatedly for an interim to plug each gap as it arises, and in doing so to avoid the harder, more valuable work of planning its own renewal in an orderly way. An interim is a sensible bridge; it is a poor permanent strategy. A board that finds itself relying on a series of interims to stay functional is usually a board that has neglected succession, and the right response is not another interim but the planning discussed in succession planning for NEDs: why boards must plan ahead. Used well — as a deliberate bridge for a defined need, not a habit — an interim appointment is a valuable tool; used as a way of avoiding proper planning, it stores up problems. Weighing these pros and cons against the specific situation, rather than reaching reflexively for the quick option, is what separates a sound decision from a convenient one. The parallel trade-offs in choosing an external rather than internal appointment are examined in the pros and cons of recruiting an external NED.
