Heidrick & Struggles has warned that UK boards are increasingly favouring experienced, financially trained, and internationally mobile chief executives, creating a narrower path to the top at major companies.
The executive search and leadership advisory business published its Route to the Top Europe 2026 report, tracking the backgrounds and career paths of 522 CEOs at the largest companies across Europe. The report also includes survey findings from 299 European CEOs and board members on succession planning and leadership alignment.
The research found that 41% of newly appointed CEOs across Europe’s largest listed companies had previously held a CEO title, as boards respond to uncertainty by seeking proven leaders. The average age at appointment in Europe has risen from 56 in 2021 to 57.5 in 2026.
The UK profile is particularly distinctive. Thirty-two per cent of UK CEOs previously held a CFO role, the highest proportion in Europe and well above the European average of 22%. Only 8% of current UK CEOs were appointed before the age of 45, the second-lowest figure in Europe.
The research also found that 47% of CEOs at the UK’s largest companies are not British nationals, the highest proportion of any major European economy. France, by comparison, has 18% non-national CEOs. Heidrick & Struggles said the UK’s openness to international leadership talent underlines its draw for global executives, but also raises questions about the depth of the domestic pipeline.
Jenni Hibbert, regional leader for Europe and Africa and global managing partner, leadership insights, said: “The data paints a detailed picture of who is running UK PLC in 2026. The path to the top has narrowed over time and the profile it rewards is increasingly specific. What should concern boards is not just who is getting through, but who isn’t.”
She added: “When nearly half your CEOs come from overseas, one in three came through finance, and fewer than one in 10 were appointed before 45, you have to ask whether the pipeline is genuinely open or whether it just looks that way.”
The report also identifies a succession blind spot. UK and Irish organisations recorded the strongest leadership alignment scores in Europe, with 19% describing themselves as highly aligned against a European average of 11%. Yet they were also the most likely in Europe to say CEO succession planning is not a high priority, at 43% against a European average of 33%.
Heidrick & Struggles said European companies with high alignment and the right CEO in place are 10 percentage points more likely to exceed financial performance expectations than peers, at 34% compared with 24%.
The report also shows slow progress on gender diversity. Just 8% of UK CEOs are women, in line with the European average. Across Europe, the figure has moved only from 6% in 2021 to 8% in 2026.
The findings land at a difficult point for boards. Companies are facing low growth, energy uncertainty, trade disruption, technology change, regulatory pressure, workforce transformation, and investor scrutiny. In that environment, boards may prefer leaders who have already held the top job or who bring finance-led credibility with markets and lenders.
Caution can reinforce a narrow model of leadership. A heavy preference for prior CEO or CFO experience can reduce opportunities for operational, commercial, technology, people, customer, or transformation leaders. It may also make it harder for younger executives and women to reach the final shortlist unless they already fit an established pattern.
Finance experience is particularly valued in the UK because listed-company leadership requires market communication, capital allocation, regulatory confidence, and performance discipline. That does not make the CFO route inappropriate. It does, however, raise questions about whether boards are giving equal weight to product, customer, digital, people, and international growth capability.
Succession planning is the weak point. If boards want more diverse CEO options, the work must begin years before a vacancy. Internal candidates need stretch roles, investor exposure, cross-border assignments, crisis leadership, board contact, and operating responsibility. Without that deliberate development, boards may default to the safest external profile when pressure rises.
The report suggests that many UK organisations feel aligned but are not treating CEO succession as a discipline. Alignment can deteriorate quickly if a company loses a leader, faces activist pressure, suffers a performance shock, or needs a strategy reset. A narrow pipeline then becomes a strategic constraint rather than a diversity issue alone.
UK companies have long drawn strength from international openness and financial sophistication. The next test is whether boards can retain those advantages while widening the route to the top.
