Key Person Insurance: Protecting Your Business's Most Valuable Asset

Key person insurance explained: what it covers, who needs it, how to estimate the right amount, and how it's typically structured for UK businesses.

The simple answer

Key person insurance protects a business if a critical person dies or becomes seriously ill and the company suffers a financial hit as a result.

It's not about "emotion". It's about protecting:

• profit
• contracts
• growth plans
• loan obligations
• the cost/time to replace expertise

Key takeaways

• The "key person" is often the rainmaker, technical lead, or ops backbone
• Cover amount should match the business risk (not guesswork)
• Structure and tax treatment depend on purpose—get accountant input

Who is a "key person"?

Someone whose absence would materially damage:

• revenue generation
• delivery/operations
• customer retention
• funding confidence

What can key person cover include?

• Life cover (death)
• Critical illness cover (serious diagnosis)
• Sometimes income-style cover depending on setup and insurer options

How to estimate the right amount (simple methods)

Choose an approach that matches the risk:

1. Profit protection: (annual gross profit) × (months/12 needed to recover)
2. Replacement cost: recruitment + training + ramp time + lost productivity
3. Debt/loan protection: amount needed to cover loan obligations or covenants

Example (profit protection)

• Gross profit contribution from key person: £200k/year
• Recovery time if absent: 12 months
• Cover: ~£200k (plus recruitment/ramp costs if relevant)

Common mistakes

• "One-size-fits-all" numbers
• Not aligning cover to the actual business exposure
• Arranging cover without considering the legal/accounting structure
