In most small and medium sized businesses, success is not evenly distributed.

Revenue, knowledge, client trust and strategic direction often sit with a handful of individuals. Sometimes just one.

You may not formally label them as “key people”, but if you paused for a moment, their names would come to mind immediately.

The more important question is this: have you protected the business against the risk of losing them?

Who are the key people in your business?

For limited company directors and decision makers, key people tend to fall into familiar categories.

• The founder or CEO who drives vision and secures major contracts.
• The IT manager who understands the infrastructure.
• The compliance lead who ensures the business stays on the right side of regulation.
• The sales director who owns the largest client relationships.
• The operations manager who quietly ensures delivery runs smoothly every day.

These individuals often carry more than their job description suggests. They hold institutional knowledge, commercial relationships and decision making authority that is difficult to replicate.

In growing SMEs, this concentration of responsibility is common. It is also where risk quietly builds.

If they were gone tomorrow, what changes?

It is not a comfortable exercise, but it is a necessary one.

• If a key employee suddenly passed away, would revenue fall?
• Would senior leaders be forced back into day to day management, sacrificing strategic growth?
• Would other team members feel stretched, leading to drops in morale and productivity?
• Would clients question stability?

In many businesses, the answer to at least one of those questions is yes.

And yet, very few board discussions formally quantify this risk.

The ripple effect directors often underestimate

The loss of a key person rarely affects just one area.

• Revenue can dip quickly if client relationships are personal.
• Recruitment costs can be high, especially for specialist or leadership roles.
• Training and onboarding can take months before performance stabilises.
• Senior leaders may need to step into operational gaps, delaying expansion plans or funding conversations.

There is also a psychological cost. Teams under pressure for prolonged periods often see productivity decline. High performers may even look elsewhere if they feel instability.

For directors focused on growth and long term value, these ripple effects matter just as much as immediate cashflow.

A scenario that can affect any business

Consider a manufacturing SME with a turnover of £3 million. The operations director has spent years refining supplier relationships and internal processes. Margins are tight, and efficiency is key.

If that operations director were to die unexpectedly, the impact would be immediate. Supplier negotiations would stall. Production delays would increase. Senior leadership would have to absorb operational oversight, pulling attention away from expansion plans and new contracts.

Revenue would likely dip within the first quarter. Recruitment for a like for like replacement could take six months or more, with significant agency fees and a higher salary expectation.

Now imagine the same business with planning in place.

A key person insurance policy pays a lump sum to the company. That capital allows the business to:

• Cover temporary operational inefficiencies
• Hire an experienced interimconsultant
• Fund recruitment and onboarding without straining cashflow
• Reassure lenders and major clients that continuity is secure

The business still faces disruption, but it avoids financial distress. Most importantly, it buys time. Time to make measured decisions rather than reactive ones.

Why this conversation matters at board level

Protecting key people is not about pessimism. It is about responsible governance.

Directors have a duty not only to grow the business, but to safeguard it. Identifying key person risk and planning for it demonstrates thoughtfulness to investors, lenders and stakeholders.

Key person insurance is a way businesses address this exposure. It is designed to provide financial stability to the company if a crucial individual dies or suffers a critical illness. The policy is owned by the businessand pays out to the business, creating a financial buffer at precisely the moment it is needed most.

It is not about replacing a person. It is about protecting continuity.

A practical exercise for decision makers

If you are part of a leadership team, consider running a simple internal review:

• List the top individuals whose absencewould most disrupt revenue or operations.
• Estimate how long it would take to replace them effectively.
• Calculate the potential revenue shortfall over that period.
• Assess whether current reserves would comfortably absorb that shock.

For many SMEs, the gap between risk and preparation becomes clear very quickly.

Growth is stronger when it is protected

Ambition drives SMEs forward. But ambition without resilience can leave value exposed.

Every SME has a key person. Often more than one. The real differentiator is whether the business has acknowledged that dependency and taken steps to manage it.

If you have never formally reviewed your exposure, now may be the right time to start that conversation.

Because protecting your key people is ultimately about protecting the business they helped build.
