Authority in Abeyance: Governing a UK Group Through a CEO Vacancy

The vacancy is a state, not a gap

When a group chief executive leaves, the instinct in many UK boards is to treat the period that follows as a corridor: something to be walked through quickly on the way to a permanent appointment. The search is launched, a headhunter is engaged, and the organisation is asked, implicitly, to hold its shape until the new arrival appears.

That framing is understandable and usually unwise. A CEO vacancy is not an absence of governance; it is a different configuration of it. Decision rights move, or ought to. The board's attention shifts from oversight of an executive to stewardship of an institution. Employees, lenders, customers and — in listed or regulated groups — the market all read the interval for signals about control. What they see is rarely neutral.

The UK Corporate Governance Code, in its 2024 revision, continues to place the responsibility for a framework of prudent and effective controls with the board. Nothing in that expectation is suspended because the top chair is empty. If anything, the test is sharper: the controls must now work without the person around whom many of them were informally arranged.

The purpose of this article is to set out what a UK group board can decide in calm conditions so that the organisation keeps moving — deliberately, and without drift — when conditions are not calm.

Decide the mandate before the moment arrives

Most groups have a delegated authority matrix that quietly assumes a chief executive exists. It is worth checking whether yours survives the assumption being removed. The articles of association, the schedule of matters reserved for the board, and the delegated limits for capital expenditure and contracts should all be reviewed against a simple question: who signs, and up to what value, when there is no CEO?

A standing protocol, adopted in advance and refreshed annually, removes the improvisation. It should cover at least the following.

Title and status. Whether the appointee is an interim group chief executive, an acting chief executive, or an executive chair is not a semantic matter. Each carries different implied authority, different market expectations and, for regulated entities, potentially different notification requirements. Choose the label deliberately and use it consistently.

Reserved matters for the interval. Certain decisions — material acquisitions or disposals, refinancing, changes to the dividend, restructurings affecting more than a defined number of roles — should be reserved to the board for the duration, irrespective of the interim's seniority. A short, written list is more useful than a long, ambiguous one.

A second signature. For commitments above a defined threshold, require dual authorisation: the interim executive and the chair, or the interim and the audit committee chair for financial matters. This is not distrust; it is the governance equivalent of a temporary speed limit.

The interim's relationship with the board. Does the interim sit on the board? Attend but not vote? Report to the chair rather than the board as a whole? Each arrangement has merits, but the ambiguity of leaving it unspecified is worse than any of them.

Consultancy and handover terms. Where a departing chief executive remains available on a retainer, define the boundaries in writing: what they may be consulted on, who may consult them, and — critically — that they do not attend executive meetings or communicate directly with staff on operational matters.

Cadence without a centre of gravity

A common failure in the interim period is that the board meets more often but decides less, because meetings become updates rather than forums for judgement. The remedy is rhythm with purpose.

A fortnightly board session of sixty to ninety minutes, with a fixed agenda of standing items — trading, cash, people, risk, and the search itself — works better than a monthly marathon. Between sessions, the chair and the interim should meet weekly, briefly and in person where possible. The executive committee should continue on its normal schedule, chaired by the interim, with a single decision log shared with the board.

What must not emerge is a shadow centre of authority. If the search committee, the chair, the former chief executive and the interim are all, in different ways, understood to be in charge, the organisation will find its own way to interpret the ambiguity — and that interpretation may not be the one the board intended.

One message, repeated without embellishment

The external and internal narrative during a vacancy is usually less about what is said and more about whether it is said consistently. Employees notice when the story changes between the town hall and the team meeting; investors notice when the line changes between the results call and the private briefing.

For staff, the essential content is unglamorous: what has changed, what has not, who is accountable for what, and how to escalate a concern. It should be delivered by the chair and the interim together, in writing, and repeated at intervals rather than announced once.

For investors and lenders, the discipline is the same message with a single point of contact. Resist the temptation to speculate on the timetable for appointment. Provide the information that obligations require — inside information handling, market notifications, covenant reporting — and decline the rest. A calm, consistent refusal to speculate reads as control. A series of small, well-meaning clarifications reads as the opposite.

Customers and key suppliers benefit from a short continuity letter, signed by the chair and the interim, confirming commercial terms and named contacts. It takes an hour to draft and prevents weeks of quiet anxiety on the other side of the table.

The risks that accumulate quietly

The dangers of a prolonged vacancy are rarely dramatic. They are cumulative, and they tend to fall into five categories.

Strategic drift. Initiatives paused for the interval are quietly cancelled by inertia. Keep a register of deferred decisions with a review date, so that deferral remains a choice rather than a default.

Unauthorised commitment. Well-intentioned executives sign contracts or make hiring promises that the permanent chief executive will inherit. The dual-signature rule and the reserved matters list exist precisely for this.

Talent flight. Senior people leave not because of the vacancy itself but because no one is sponsoring their development. Assign each member of the executive team a board sponsor for the duration.

Narrowed board attention. The search consumes the board's energy, and oversight of the underlying business thins. Ring-fence search business to a separate committee agenda item.

Caretaker capture. The interim becomes permanent by default, without a decision ever being taken. Set an explicit review date — twelve weeks is a reasonable first checkpoint — at which the board either confirms the arrangement with reasons or recommits to the external process.

The handover artefact

Finally, treat the interim period as an opportunity to build something the incoming chief executive will need anyway: a running state-of-the-group note, updated weekly by the interim and reviewed by the chair. It records open issues, live decisions, key relationships and known risks, in plain language, without the polish of a board pack. Handed over on day one, it is worth more than a hundred slide deck inductions.

An empty chair at the top of a UK group is not, in itself, a crisis. It becomes one only when the board treats it as a gap to be endured rather than a condition to be governed. The organisations that navigate these intervals well are rarely the ones that find a successor fastest. They are the ones that decided, in advance, how authority would behave while no one held it permanently.
