CEO Executive Search: How Boards Appoint a Chief Executive 

CEO executive search is the confidential, board-led process of identifying, assessing and appointing a chief executive, usually with an external partner mapping the whole market rather than waiting for applications. It differs from every other hire because the people making the decision will be judged on it by shareholders, regulators and staff, and because the person being replaced may still be in the building. 

What is CEO executive search? 

If you’ve read our explanation of what executive search is and how the retained model works, you’ll know the method: a retained partner, a mapped market, discreet approaches to people who aren’t looking. Chief executive recruitment uses the same method with the stakes raised, and replacing a CEO happens less often than you might expect. 

Fourteen FTSE 100 companies changed chief executive in 2025, a fraction above the long-term average of 13 since 2000, and the average sitting FTSE 100 CEO has been in post for 71 months, according to AJ Bell’s review of 2025 boardroom moves. That’s a stable market, and it means a typical board runs a CEO search about once every six years. 

Set that against the nine-year limit on non-executive independence and most directors sit through one CEO appointment, perhaps two. That gap in memory, rather than any shortage of contacts, is the real reason boards bring in outside help. 

Why a CEO appointment is different from any other senior hire 

1. The board owns the decision, not the executive team 

For every other senior hire, the chief executive is the client. For this one, you are. The UK Corporate Governance Code asks for ‘a formal, rigorous and transparent procedure’ for appointments and ‘an effective succession plan for the board and senior management’ under Principle J, and gives the nomination committee responsibility for ‘orderly succession to both the board and senior management positions’ in Provision 17, as set out on the FRC’s UK Corporate Governance Code page.  

The Code applies to premium-listed companies, but the principle holds everywhere: under the model articles a director is appointed ‘by ordinary resolution, or by a decision of the directors’. Whoever signs the accounts appoints the person who runs the business. 

2. The cost of getting it wrong 

The encouraging news is that the biggest driver of a poor appointment is one you control. A study of 1,275 US CEO appointments between 2001 and 2014 found that ‘a one standard deviation increase in corporate misfit results in an extra 5.6% decline in performance for outside CEOs compared to inside CEOs’, as reported by Keil, Lavie and Pavićević in the Academy of Management Journal in 2022. Outsiders who fitted the strategic profile did not underperform. Fit is the variable, and fit can be tested before anyone signs. 

The market gives its verdict on day one. Across every FTSE 100 CEO appointment announced in 2025 to 11 November, AJ Bell’s analysts found that ‘stocks fell by an average 0.8% on the day’, with a range from Diageo’s 5.2% rise to Berkeley Group’s 8.9% fall. 

3. Confidentiality when there’s an incumbent in post 

In a listed company, a CEO’s planned departure will usually be inside information, which turns discretion into a legal duty and hands you a ready-made discipline. Article 17 of UK MAR permits delayed disclosure only while the issuer ‘is able to ensure the confidentiality of that information’, and the FCA’s guidance in DTR 2.5 is blunt: ‘the wider the group of recipients of inside information the greater the likelihood of a leak which will trigger full public disclosure’. The FCA fined Sir Christopher Gent, former chairman of ConvaTec, £80,000 in 2022 for disclosing inside information to two major shareholders, including ‘the CEO’s plans for retirement’. 

Private companies aren’t bound by MAR, but the discipline travels well: a named circle who know, a holding statement drafted before the first approach and a partner who fronts the market so your name never has to. 

4. The candidate is assessing you as much as you’re assessing them 

The people you want are already running something, and they’ll weigh your board’s clarity long before the package. In PwC’s 29th Global CEO Survey of 4,454 chief executives, 42% named ‘whether their company is transforming fast enough to keep pace with technological change, including AI’ as their top concern. A serious candidate will ask how realistic your expectations on that front are, and read the answer as a signal about the board. There’s a reassuring corollary: a candidate who presses you on the mandate is showing you, live, the judgement you’re hiring for. 

The CEO recruitment process, step by step 

Those four differences shape every stage of the CEO search process. This is the sequence we use when recruiting a chief executive. 

1. Board alignment on the mandate 

Agree what the next three years require before any name is discussed. The FRC’s guidance to nomination committees says they should ‘agree the process to be undertaken to identify, sift and interview suitable candidates’. Decide who decides, and who sits inside the confidential circle. 

2. Defining the role against strategy, not the last CEO 

Write the specification from the strategy forward. In the KPMG CEO Outlook for the UK, 54% of chief executives said their role has ‘evolved significantly’. Ask what the business needs, not who it had. 

3. Market mapping and longlisting 

Before anyone is contacted, map every plausible candidate: sitting chief executives, divisional CEOs of larger groups, strong number twos. A good longlist includes people you hadn’t thought of. 

4. Discreet approach and engagement 

Your partner makes first contact without naming you until interest and confidentiality are both confirmed. 

5. Assessment, referencing and psychometrics 

The same FRC guidance asks boards to ‘build a proper assessment of values and expected behaviours into the recruitment process’. Structured interviews, referencing beyond the candidate’s own list and psychometrics that inform judgement rather than replace it. 

6. Board interviews and stakeholder exposure 

The full board meets the final two or three. The chair and senior independent director hold separate conversations, and major shareholders are consulted where it’s appropriate and lawful. 

7. Offer, notice and counter-offer management 

Investors have written down what they expect of any board-level hire. The Investment Association’s Principles of Remuneration state that ‘notice periods for executives should be of one year or less’ and that committees are ‘encouraged to not automatically match or increase upon the salary of the predecessor’. Build that rationale before the offer, not at the AGM. 

8. Onboarding and the first 100 days 

The 2026 pattern is a designate period: Chemring’s incoming chief executive joins as Group Chief Executive Designate on 5 October 2026 and takes over on 1 January 2027, per the company’s announcement. Use those weeks for a structured handover, and brief the incoming CEO on Provision 29, under which the FRC expects most companies to identify ‘somewhere between 30 and 50 material controls’. 

Which of those eight steps in the CEO appointment process would your board compress if the CEO resigned tomorrow? That’s the one to protect now. You can see how we run an executive search from mandate to onboarding. 

How long does a CEO search take? 

Hiring a chief executive runs on two clocks: the time to name a successor and the time until they start. Trainline’s Jody Ford signalled his departure on 25 February 2026; Ian Brown was named on 24 June after a ‘comprehensive search process’ and becomes chief executive on 28 September, as the Trainline announcement sets out. Four months to name, seven to start, no interim because the incumbent stayed. BP named Meg O’Neill on 17 December 2025 yet she started on 1 April 2026, because a sitting chief executive had to be released, per BP’s announcement. OSB Group named its new CEO on 20 February 2026 ‘subject to regulatory approval’, starting 1 September, according to OSB’s announcement. Regulated sectors add a leg you can’t shorten. 

For private equity owners, the AlixPartners survey of 427 PE and portfolio company leaders puts an external CEO search at four to six months, while McKinsey’s July 2026 note cautions that ‘a new PE CEO search can take six to 12 months, or longer’. What stretches any timeline is predictable: notice periods and garden leave, regulatory approval, board diaries and restarts when a shortlist doesn’t hold. 

Plan backwards from the start date rather than forwards from the resignation. If the ideal candidate is a sitting CEO on twelve months’ notice, the realistic horizon is a year, and the decision for week one is who leads in the meantime. Reading the current senior leadership market helps you set that horizon. 

Internal succession or external search? 

The fastest way to shorten every clock is to have started before the vacancy. The CIPD’s succession planning factsheet sets out the method; CEO succession planning is where most boards haven’t applied it. In Grant Thornton’s review of 216 FTSE 350 annual reports, ‘succession planning reporting was identified as an improvement area at 40% (2024: 38%)’, as the firm’s January 2026 findings put it. The Institute of Directors found ‘more than a third of companies had not undertaken any form of succession planning for the CEO’, with planning typically starting ‘about two years before the current chief executive’s planned departure’. Two years is plenty, if you begin now. 

When to promote from within 

The internal route works when the strategy calls for continuity and a credible successor exists. Eurocell appointed CFO-designate Will Truman as chief executive ‘commencing immediately’ on 9 February 2026 because the board wanted ‘surety of leadership and a seamless handover’, as its stock exchange announcement explained. That option existed only because he was already in the building, and the same AlixPartners survey shows how rare that is in private equity: only 43% of PE firms and 29% of portfolio companies had a successor in mind. 

When the business needs an outside view 

When the strategy changes, the search should too. A meta-analysis of 13,578 successions in The Leadership Quarterly found outsiders drive strategic change, and the fit research from Keil and colleagues tells you when that change pays. Of the twelve UK chief executive successions we followed between mid-2025 and August 2026, seven went external. In our reading that says less about the quality of internal benches than about how often a change of strategy arrives with a change of leader. 

Running a dual-track process 

A dual track is a benchmark, not a beauty contest. Rank Group made its CFO interim chief executive in January 2026, ran ‘an extensive executive search process’ that ‘considered both internal and external candidates’ and confirmed him in July, as the Rank Group announcement records. Domino’s did the same with Nicola Frampton, confirming its interim as permanent chief executive in March 2026. An insider who wins a real contest takes the job with a mandate no coronation could give. 

What happens to the internal candidate who doesn’t get it 

Plan this before the process starts. The interim can revert to their substantive role with a wider remit. The long-serving executive can return in a different seat: Ultimate Products’ Andrew Gossage steps down after more than 20 years and returns as a non-executive director on 1 May 2027, while founder Simon Showman described his successor as “our first external CEO”, per the company’s May 2026 announcement. Tell the runner-up personally and quickly. A strong internal candidate who loses to a better-fitting outsider and stays is proof the process was real. Our guide to developing your leadership pipeline covers building that bench. 

Founder to CEO: hiring your first external chief executive 

For one group of owners, the internal candidate is themselves. 

Signs it’s time to step back 

The question of when to hire a CEO for a start-up or founder-led business usually answers itself: your calendar is the bottleneck, investors want a defined leadership structure or the next phase needs a skill set you don’t want to build. Oxford Nanopore’s co-founder Gordon Sanghera told his board on 11 August 2025 he intended to step down by the end of 2026, saying “it has been important to me that the Board have ample time to identify a successor”; the external hire started on 2 March 2026, as the company’s appointment release records. The lesson is the notice period, not the exit. 

Defining the founder’s ongoing role 

Decide your next title before the search begins, as candidates will ask. Ocado committed on 6 July 2026 that Tim Steiner stays CEO until the 2028 financial year and then remains through 2029 in a founder role, according to Reuters. The governance case for founder-as-chair is written down too: the Wates Principles say ‘consideration should be given to separating the roles of the chair and chief executive to ensure a balance of power and effective decision-making’. 

Protecting culture through the transition 

A US Census Bureau working paper published in 2026 finds founder departures significantly increase employee turnover; that’s the case for overlap, visible endorsement and a handover that is designed rather than hoped for. Culture transfers when the people carrying it can see the founder backing the successor. 

If the person you appoint disagrees with you in year one, and turns out to be right, what would you need to have agreed today for that to feel like success rather than betrayal? 

Interim and fractional CEO appointments 

Not every transition needs a permanent appointment on day one. Interim leadership featured in five of the twelve successions we followed, usually the finance director, and the market behind it is mature. The Institute of Interim Management’s 2026 survey puts the average UK interim day rate at £907, the average assignment at 10.0 months and C-suite roles at 38% of the total. Fractional arrangements are opening the option to smaller companies: The Times reported in June 2025 that UK LinkedIn profiles describing fractional leadership roles had reached around 110,000, from about 2,000 in 2022. 

Interim suits a defined gap with a full-time need; fractional suits smaller businesses that want CEO-level judgement a few days a week. Our interim and contract leadership work covers both. A ten-month assignment at those rates is a six-figure decision, so treat it as one: give the interim a written mandate, a board sponsor and an explicit statement of whether they’re a candidate for the permanent role. Ambiguity on that last point turns a bridge into a bottleneck. 

Working with a CEO executive search firm 

Most boards will use outside help, whether they call them CEO recruiters, CEO recruitment agencies or CEO search firms. The useful question is what standard to hold your partner to, and the Code supplies one. Provision 20 of the UK Corporate Governance Code, written for chair and non-executive appointments, requires an engaged search consultancy to be ‘identified in the annual report alongside a statement about any other connection it has with the company or individual directors’. It doesn’t apply to CEO hires, but nothing stops you borrowing the test: independence, disclosed connections and a partner willing to be named. 

Several 2026 announcements state that the board was supported by external search; that transparency costs nothing and signals a process the market can trust. For fee models and how to compare firms, see our guides to how retained search works and choosing a C-suite search firm. 

Building a diverse CEO shortlist 

One test of any partner is the breadth of the list they bring, because the pipeline exists and the shortlist is where it narrows. 

Women hold 21 FTSE 350 chief executive roles, 8.2%, but make up 29.3% of executive committee members and 37.0% of direct reports, according to the FTSE Women Leaders Review of February 2026, which calls the CEO role ‘the slowest to change’. The talent is one and two levels down; the appointment rate is the bottleneck. The Parker Review reported a record 14 ethnic minority FTSE 100 chief executives in March 2026, noting ‘none of the 14 FTSE 100 ethnic minority CEOs are women’. 

The mechanism you can act on in any chief executive appointment is the finalist pool. University of Colorado Boulder research, first published in 2016, found that with one woman in a finalist pool her odds of appointment were statistically negligible; with at least two, ‘the odds of a woman being hired were almost 79 times greater’. The FRC’s guidance names ‘choosing executive search firms that are known for drawing up diverse longlists’ as a lever. It’s why our work supporting female leaders and our B Corp certification sit alongside our search practice. 

Think back to your last shortlist. How many finalists were the only person of their kind in the room? 

Appointing your next chief executive 

It comes down to four decisions a board can take this quarter, while the current chief executive is thriving and nobody is watching the clock: 

• Open the succession conversation now, with a written contingency plan and a two-year horizon for the planned route. 

• Agree in advance how internal and external candidates will be compared, so the eventual choice carries a real mandate. 

• Settle who knows, who speaks and what gets said if it leaks, before the first approach. 

• Write the fit criteria against the next strategy before you see a single CV. 

The best CEO appointments make very little noise. The share price shrugs, the staff nod, the strategy continues. That stillness is the product of eighteen months of work nobody saw.
