Succession planning has been on the HR agenda for decades, yet the same issues continue to surface. Despite widespread acknowledgement of its importance, many firms remain exposed to leadership disruption, operational risk and talent gaps. This disconnect is now beginning to impact business continuity, growth and long-term strategy.
Indeed, our recent research revealed a stark reality for many companies. While 39% of businesses say that succession planning is embedded and regularly reviewed, a staggering 61% have yet to implement a comprehensive strategy and a further 22% admit it is not part of their approach at all. This gap between awareness and execution is at the heart of why succession planning remains a persistent challenge.
The gap between intent and action
Most firms recognise that succession planning is important, but fewer treat it as a core, continuous process. Instead, it is often approached as a periodic exercise, triggered by retirement announcements or unexpected departures. This reactive mindset creates a structural vulnerability that we have seen so many businesses fall victim to. Without a clear pipeline of future leaders, employers are forced into last minute hiring decisions when critical roles become vacant. Not only is this time consuming but it also introduces risk around cultural fit, capability and long-term alignment with the company.
The impact is most visible in decision making and delivery. Leadership gaps can delay key projects, disrupt operations and create uncertainty across teams and stakeholders. In sectors where roles are highly specialised or tied to operational outcomes, such disruption can directly affect performance, growth and stakeholder investment.
The retirement cliff is accelerating the problem
The succession planning challenge is being intensified by a significant demographic shift in many C-Suites. Across industrial, infrastructure and energy sectors in particular, we’re seeing a large number of experienced professionals reaching retirement over a concentrated period.
This retirement cliff is not a new concept, but its timing is critical. These industries are simultaneously managing increasing complexity, regulatory demands and large-scale investment programmes. As a result, the loss of senior expertise is occurring as the need for capable leadership is rising.
The issue is not simply one of losing or replacing headcount, however. Many senior leaders hold deep, experience-based knowledge built over decades that is difficult to transfer quickly. Their contribution extends beyond formal responsibilities to include judgement, problem solving and an understanding of how systems operate in practice. Without structured succession planning and knowledge transfer, that expertise leaves with them, en masse.
Leadership capability versus future demand
Even where firms have identified successors, there is often a gap between potential and readiness. Leadership development takes time, particularly in sectors where progression is tied to real world experience rather than accelerated career pathways. At the same time, expectations of today’s leaders are evolving. Businesses are navigating technological change, regulatory pressures and new delivery models. This is increasing both the breadth and depth of capability required at senior level. The result is a mismatch between the leaders that firms need and the pipelines they have in place. In essence, succession planning simply isn’t keeping pace with how leadership roles are changing.
Sector pressures are exposing the cracks
The impact of these weak succession plans is particularly acute in sectors such as energy, engineering and infrastructure. These environments rely heavily on specialist expertise and operational continuity. In the energy sector, for example, leadership capability is directly linked to the UK’s ability to meet long term targets such as net zero. Delivering on these ambitions requires sustained investment, technical knowledge and strategic oversight. At the same time, firms are facing skills shortages and increased competition for experienced talent.
Without a strong leadership pipeline, businesses risk struggling to deliver complex projects and respond to changing demands. Succession planning, therefore, is not just a workforce issue, it is a strategic risk linked to wider economic and societal goals.
Why succession planning still falls short
There are several reasons why firms continue to struggle to get succession planning right. It is often deprioritised, with immediate operational demands understandably taking precedence over longer term planning, even when leaders acknowledge the importance of succession. There is also a lack of ownership in many cases. Succession planning can sit between HR and senior leadership without clear accountability, resulting in inconsistent execution.
Unfortunately, the process itself is also frequently misunderstood. Identifying potential successors is only one part of the equation, and effective succession planning requires ongoing development, structured pathways and active management of talent pipelines. I would argue that there is also a tendency to underestimate the pace of change. Leadership transitions are no longer predictable or linear. Career moves, market shifts and external pressures mean that roles can change quickly, leaving little room for the reactive approaches that have become the norm.
Moving from reactive to strategic
The businesses that are getting succession planning right share a common approach; they treat it as an integral part of strategic workforce planning rather than a standalone HR activity. This means aligning succession planning with business objectives, identifying critical roles and developing talent well in advance of vacancies arising. It also requires a focus on knowledge transfer, particularly as experienced leaders approach retirement.
Crucially, it involves embedding succession planning into day-to-day operations rather than revisiting it periodically. Firms that take this proactive approach are far better positioned to maintain continuity, protect expertise and support long term growth.
A growing leadership risk
While a longer-term strategy, succession planning isn’t a future concern, it is a modern day risk that is already affecting business performance. As leadership roles become more specialised and harder to fill, and as experienced professionals continue to exit the workforce en masse, the cost of inaction is rising. Businesses without a clear pipeline of future leaders are more likely to face disruption, delays and missed opportunities.
For HR leaders, the challenge is clear. Succession planning must move from intention to execution. The tools and frameworks to do this already exist, but what is required now is consistent application, clear ownership and a shift in mindset from reactive to strategic. Only then will succession planning deliver what it promises: stability, resilience and the leadership capability needed for the future.
