Succession planning: a UK guide for HR leaders

Dealing with the day-to-day activities of running a business can take up most of your time, so looking ahead requires planning and forethought. It’s worthwhile taking the time to think about what lies ahead, as it’s inevitable that your leaders and top talent will eventually either leave or retire. The focus here is on succession planning.

Succession planning identifies and develops employees that can step into leadership and business-critical roles in the future. For HR professionals, it’s part of the broader workforce planning and talent management strategy, helping companies to retain institutional knowledge and build a stronger internal pipeline. While often reserved for the most senior posts, succession planning can be used for running local models across sites or countries as well.

Instead of waiting for top talent to either resign or retire, proactively honing in on potential successors, assessing their readiness, and investing in targeted development programmes is the best way to go for the HR department. While the pressure is on to retain high-achieving colleagues, with all the inside knowledge that they possess, the reality is that leaders move on, often to bigger and better things. 

The modern approach to succession planning places a greater emphasis on talent pools, internal mobility, and long-term capability building. This is much more sustainable and inclusive, rather than naming just one successor, as used to be the case with traditional succession planning. The new approach dovetails with the Chartered Institute of Personnel and Development (CIPD) guidance, which positions succession planning within wider workforce intelligence planning and talent management.

For HR leaders, succession planning should answer 4 basic questions:

• Which roles would create significant business risk if they became vacant?
• Who has the potential to succeed in those positions?
• How ready are they now?
• What career development will help them to prepare for future opportunities?

Succession planning reduces business risk while strengthening the long-term performance of an organisation.

Every organisation experiences leadership transitions for a variety of reasons, such as promotion, resignation, retirement, or restructuring. If no succession plan is in place, these changes can seriously disrupt operations, delay decision-making, and increase recruitment costs.

Effective succession planning helps organisations to:

• Retain critical organisational knowledge.
• Maintain business continuity.
• Improve leadership capability.
• Increase employee engagement with transparent and visible career opportunities.
• Reduce reliance on expensive external recruitment processes.
• Support diversity within leadership pipelines.

Recruitment challenges are rife across most sectors, and have been for some time across the UK labour market. According to the Office for National Statistics (ONS), UK vacancies are still above pre-pandemic levels, despite easing from their peak, with 620,000 vacancies listed in the period between April and June 2026. This means that replacing senior talent externally is often slower and more competitive than developing people within the organisation.

A well-designed succession planning template delivers benefits for both the organisation and its employees.

For employers, succession planning reduces the dependency on individual leaders, so that organisations can set out a talent acquisition strategy and identify future capability gaps before they evolve into business risks. It also enables HR teams to make more informed decisions about future capabilities, rather than reacting to vacancies as they arise.

For employees, any visible development opportunities improve engagement and retention. High-potential employees are more likely to stay with an organisation that demonstrates clear career pathways and invests in their progression.

Wider organisational benefits include:

• More effective and quicker leadership transitions.
• Reduced recruitment costs.
• Improved workforce planning.
• Increased retention of high performers.
• Greater organisational agility.
• A stronger employer brand.

In order to achieve an effective succession planning process, follow these 4 connected stages, which move from identifying risk to developing future leaders.

First of all, identify roles with the greatest organisational impact, the loss of which would significantly affect organisational performance – not necessarily those that are the most senior. Many organisations still hone in on executive succession on an exclusive basis, to the detriment of other positions which are more critical to the company. The CHRO and their team should assess roles based on the following factors:

• Specialist knowledge.
• Impact on business continuity.
• Leadership influence.
• The difficulty of recruiting replacements externally.
• Regulatory responsibility.
• The time it takes to develop internal capability.

Critical roles are positions such as Regional Director, Programme Director, Technical Specialist, Cybersecurity Leader, and Operations Director. Prioritising these critical roles ensures succession planning resources are focused on where organisational risk is at its highest.

Create a risk matrix that considers:

• The likelihood of vacancy within the next 3 to 5 years.
• The business impact if that vacancy came about unexpectedly.

Roles that combine high likelihood and high impact should be given the green light for immediate succession planning attention.

Once business-critical roles have been identified, the next step is to assess who could fill them and when, depending on each individual’s skill set. Rather than selecting successors based solely on current performance, organisations should assess both performance and future potential.

Many organisations use readiness categories such as:

Readiness level	Succession potential
Ready now	Can step into the role immediately.
Ready in 1 to 2 years	Requires targeted development.
Ready in 3 to 5 years	Demonstrates strong long-term potential.
Future potential	Earlier career talent requiring broader experience.

Objective evidence should be used to assess the employee’s readiness to take on a new role, rather than simply relying on what the line manager thinks. Useful assessment methods include:

• Performance reviews.
• Leadership and behavioural assessments.
• Psychometric profiling.
• 360^o feedback.
• Assessment centres.
• Career aspiration discussions.

Create tailored development plans, that include coaching sessions, job rotations, secondments, project leadership, mentoring programmes, and formal learning, in order to build technical capabilities and leadership behaviours. 

Traditional succession plans used to identify just one staff member for each senior role. It’s a simple yet risky approach, as what happens if that individual decides to quit or forges a different career path? It means you’re back to the drawing board. Nowadays, organisations build talent pools around leadership levels or functional capabilities, which creates flexibility while encouraging cross-functional development, job rotations, and internal mobility.

Succession planning is a continual process, so regularly reviewing talent, updating readiness assessments, and adjusting plans as the business transforms are a must. Keep a regular eye on the planning process through quarterly talent reviews, incorporating any changes in organisational strategies, the movement of employees, readiness levels, new high-potential employees, and emerging capability gaps. 

A straightforward succession planning template will help the HR department to create consistency across the organisation. Keeping the framework simple and user-friendly encourages managers to use it consistently, rather than treating succession planning as an annual administrative exercise.

A practical framework might include the following information:

Business-critical role	Current holder	Vacancy risk	Potential successors	Readiness	Development actions	Review date
Head of Operations	Fazid Mohammad	Medium	Employee A & Employee B	Ready in 1 to 2 years	Job rotation, coaching	Every quarter

Succession planning isn’t just about developing future leaders. It also supports those employees whose roles change as organisations evolve.

The succession of leaders often takes place alongside wider organisational change. New operating models, restructures, or changes in the direction of the business can create great opportunities for some, while affecting the positions of others. Providing comprehensive career transition support, including outplacement services, will help companies to manage these changes responsibly.

The benefits of outplacement include:

• Support for employees who are leaving the organisation.
• Protection of the employer brand during periods of change.
• Maintenance of trust with remaining employees.
• Reduction in reputational risk.
• A demonstrable commitment to employee wellbeing.

When succession planning is integrated with redeployment and career transition support, organisations are better placed to manage change while maintaining engagement across the workforce.

For organisations seeking to combine leadership development with responsible workforce transitions, career support from a professional company, such as Careerminds, can make a huge difference. We boast a 95% placement rate and 99% client retention, demonstrating the value of structured career transition programmes.

A. Typically it’s HR which facilitates the process, but accountability should be shared across senior leaders and line managers. That’s because effective succession planning requires full commitment from leaders, otherwise it won’t be implemented.

A. Succession planning develops future leadership capability over time through structured development and talent management. Replacement planning focuses on identifying someone to fill a position if a role suddenly becomes vacant.

A. Most organisations review succession plans annually, with more frequent discussions during quarterly talent reviews or whenever significant organisational change occurs.

A. No. While larger employers often have formal succession planning frameworks, organisations of any size can benefit from identifying critical roles, developing internal talent, and planning for future leadership needs.

Don’t wait until a key leader hands in their notice to think about succession planning. Savvy organisations are continuously building leadership capability, connecting succession planning with internal mobility and redeployment, and supporting every stage of the career transition. If your succession plan only starts when a vacancy appears, you’re already on the back foot.
