CEO Succession: What UK Nomination Committees Must Own in 2026

UK boards must treat CEO succession as a live, strategic programme — not a contingency plan kept in a drawer — yet most do not have one at all.

According to SHRM’s most recent survey on leadership continuity, 56% of organisations have no CEO succession plan in place. Only 21% have a formal, documented plan. For UK-listed companies, this gap is a governance failure: the UK Corporate Governance Code explicitly requires boards to maintain “plans in place for orderly succession to both the board and senior management positions” and to develop “a diverse pipeline of future leaders.” The Nominations Committee owns this obligation directly — it cannot be delegated to the CEO or the HR function. In 2026, as AI disrupts the skills and capabilities required of the next generation of senior leaders, the strategic dimensions of CEO succession have become more complex and more urgent simultaneously.

Why Is CEO Succession a Board Governance Priority, Not an HR Task?

CEO succession is not an HR planning exercise — it is one of the most consequential strategic decisions a board will ever make. The UK Corporate Governance Code places responsibility for succession planning squarely with the Nominations Committee, which should be chaired by an independent NED and comprise a majority of independent directors. The Committee’s role is to evaluate long-term leadership needs against the company’s strategic direction, identify capability gaps in the existing pipeline, and maintain at minimum one internal candidate with genuine readiness to assume the CEO role within twelve months.

The FRC’s Guidance on Board Effectiveness reinforces that succession planning should be a standing item at every Nominations Committee meeting — not an agenda item that appears only when the CEO announces a departure. Reactive succession creates value destruction: academic research consistently shows that unplanned CEO transitions are associated with share price volatility, strategic drift, and loss of institutional investor confidence. The most effective boards treat succession as a continuous investment in leadership readiness, with annual reviews of both the internal candidate pipeline and external market developments that might influence what capabilities the next CEO must bring. Use INFORMD’s board effectiveness assessment tools to benchmark your current succession governance against best practice.

• Executive Action: Confirm that CEO succession planning is a standing agenda item at every Nominations Committee meeting — not a periodic or contingency discussion.
• Require the Nominations Committee to maintain a written succession plan, reviewed annually, identifying at minimum one internal candidate who could assume the CEO role within twelve months with board support.
• Include a report on succession planning health in the Corporate Governance Report within the Annual Report, as expected under the UK Corporate Governance Code — and ensure the content reflects genuine engagement, not boilerplate disclosure.

How Has AI Disrupted the Assumptions Behind CEO Succession?

AI is changing what the next CEO needs to be. For most of the past two decades, FTSE 100 CEO profiles were built around sector expertise, operational scale experience, and financial performance track records. Those remain important, but they are no longer sufficient. AI is restructuring core business functions — from product development and customer engagement to supply chain, risk, and financial planning — at a pace that requires CEOs to make consequential technology governance decisions within their first year, often before they have fully settled into the role.

According to Egon Zehnder’s 2026 succession planning research, five defining trends are reshaping the criteria boards apply when assessing succession candidates: AI literacy and technology governance capability; the ability to lead organisational transformation at pace; comfort with ambiguity in regulatory and geopolitical environments; stakeholder credibility with employees on culture and values; and personal resilience under sustained public scrutiny. Nomination Committees that are evaluating successor candidates against historical CEO profiles — without updating those profiles for the 2026 operating environment — are preparing for the wrong job.

• Executive Action: Commission a CEO capability framework review in 2026 — define what the next CEO of your specific organisation needs to be able to do, set against your three-to-five year strategic plan and AI transformation agenda.
• Assess each internal succession candidate against the updated capability framework — identify specific development investments needed to close gaps before the candidate reaches readiness.
• Ensure that at least one current internal candidate has direct AI governance experience or is actively building it — boards without a succession candidate who can speak credibly to AI strategy are exposing themselves to a material gap in future leadership.

What Process Should UK Nominations Committees Follow?

Effective CEO succession follows a structured, multi-year process rather than a reactive search. The starting point is board alignment on strategy: the Nominations Committee should begin by engaging the full board on the company’s three-to-five year strategic direction, because the capabilities required in the next CEO derive from that strategy. Once aligned, the Committee identifies the three to five leadership capabilities most critical to strategy delivery and maps current senior leaders against those criteria.

The internal pipeline assessment should include structured development assignments for shortlisted candidates — cross-functional roles, board exposure, external advisory positions — that test leadership in conditions relevant to the CEO role. Boards that rely solely on annual performance reviews to assess succession readiness are missing the developmental dimension: the question is not only whether a candidate has performed well in their current role, but whether they are developing the breadth, judgment, and stakeholder presence needed at CEO level. Alongside the internal pipeline, the Nominations Committee should maintain a current view of the external market — not to create internal anxiety, but to ensure that if an internal candidate is not ready, the board has a considered view of the external field rather than starting from zero in a crisis. Access INFORMD’s board governance templates to structure your Nominations Committee succession process.

• Executive Action: Establish a three-year succession development programme for your top two internal candidates — include board presentations, external advisory roles, and cross-functional stretch assignments.
• Commission an external executive search firm to provide an annual market mapping report — not to recruit externally, but to maintain a calibrated view of the external CEO talent pool relative to internal candidates.
• Ensure emergency succession is also documented: the board should have an agreed name and process for an interim CEO appointment that could be activated within 24 hours of an unplanned CEO departure.

How Should the Nominations Committee Manage Diversity in Succession?

The UK Corporate Governance Code’s diversity provisions extend to succession planning. The Nominations Committee is required to consider the benefits of diversity — including gender, social and ethnic background, cognitive and personal strengths — when evaluating both existing board composition and the pipeline for senior leadership roles. For CEO succession specifically, this means the Committee must actively assess whether the internal candidate pool reflects the full diversity of available talent, or whether historical selection and promotion patterns have narrowed it artificially.

The FTSE Women Leaders Review and the Parker Review on ethnic diversity both provide benchmarks against which Nominations Committees can assess the breadth of their senior leadership pipeline. Boards that arrive at a CEO succession point with a shortlist of candidates who share identical backgrounds, educational routes, and career trajectories have failed their governance obligations under the Code — and, more practically, have reduced the quality of the strategic decision they are about to make. Diverse succession pipelines produce better CEO choices because they surface different perspectives on what the organisation’s next challenges require. Review INFORMD’s About INFORMD to understand how independent executive intelligence supports board decision-making.

• Executive Action: Audit the demographic and experiential diversity of your current senior leadership pipeline against the FTSE Women Leaders and Parker Review benchmarks — report findings to the full board annually.
• Ensure your Nominations Committee’s succession assessment criteria explicitly include non-traditional career routes and portfolio experience, not just FTSE-company executive track records.
• Consider independent facilitation for your succession process — external expertise reduces the risk of confirmation bias in candidate assessment and strengthens the board’s ability to defend its process to shareholders.
