What Is Key Person Insurance? Keyman Cover Explained

Most businesses insure their premises and stock, yet overlook the one asset they cannot replace overnight: their people. Key person insurance, often called keyman or key man insurance, fixes that gap. This guide explains what it is, who needs it, and how to size cover, with a link to our full keyman insurance page.

What is key person insurance?

Key person insurance is a policy a business takes out on the life, and optionally the critical illness, of an individual who is vital to its success. The business owns the policy, pays the premiums and receives any payout.

If that person dies or becomes seriously ill, the lump sum helps the business stay stable. It can cover lost profits while the company recovers, fund the recruitment and training of a replacement, and reassure banks, investors and customers that the business can continue.

Why does it matter?

In many smaller businesses, profit and relationships are concentrated in one or two people. Losing such a person can be far more damaging than losing premises or equipment, yet it is rarely insured. Key person cover turns a potential crisis into a manageable setback by putting cash in the business exactly when it is needed most.

Who counts as a key person?

A key person is anyone whose death or serious illness would materially harm the business. Typically that includes:

• Founders, owners and managing directors.
• Top salespeople or those holding key client relationships.
• Technical specialists or product leads.
• Anyone who personally guarantees business borrowing.

The more concentrated your profit, knowledge or relationships are in one or two people, the more valuable the cover becomes.

What does it pay out for?

A standard policy covers death. Many businesses add critical-illness cover, so the policy also pays out if the key person survives a serious illness but cannot work, which is statistically more likely than death during the policy term. The payout is a single lump sum to the business, which can be used however the company needs, from covering a revenue gap to repaying a loan the person guaranteed.

How much cover do you need?

There is no single rule, but two common methods help you size cover sensibly.

• Multiple of salary: often five to ten times the key person’s salary.
• Profit contribution: the share of gross profit attributable to that person, multiplied by the years it would take to recover.

You should also add any business loans or director’s loans the person guarantees, so the payout can clear them. If your business carries debt, our overview of business loans is a useful reference when sizing cover.

Key person insurance versus other business protection

It is easy to confuse the main types of business protection, because they solve different problems and are often combined.

• Key person insurance protects the company’s profits and continuity, and pays the company.
• Shareholder protection protects ownership and control, and pays the surviving shareholders.
• Relevant life cover protects an employee’s family, and pays the individual’s family.

Many businesses hold more than one. The right combination depends on your structure, your debts and who depends on the business.

What does it cost?

Premiums depend on the cover amount, the person’s age and health, whether critical illness is included, and the policy term. Cover for a healthy person in their thirties or forties is often modest relative to the protection it provides. Because pricing varies so much between insurers, comparing quotes is the only reliable way to find the right premium.

A quick note on tax

The tax treatment of key person insurance follows established principles, and premiums may sometimes be a deductible business expense. The position depends on your circumstances and is worth understanding properly, so we cover it in detail in our guide to keyman insurance tax. Always confirm the treatment with your accountant before relying on it.

How to put cover in place

1. Identify your key people and the financial impact of losing each.
2. Size the cover using salary multiples or profit contribution, plus any guaranteed debt.
3. Decide on critical illness as well as life cover.
4. Compare insurers for the right cover and premium.
5. Set it up correctly, with the business as owner and beneficiary, so the payout and tax work as intended.

Real-world scenarios where it pays out

Examples make the value concrete. Picture a design agency where one founder brings in 60% of new business through personal relationships. If that founder died suddenly, revenue would fall sharply while the remaining team scrambled to reassure clients and win replacement work. A key person payout would cover the shortfall, fund recruitment, and buy the breathing room to stabilise.

Or consider a manufacturer whose lead engineer is the only person who understands a critical process. A serious illness that kept them off work for a year could stall production entirely. Critical-illness cover within a key person policy would provide cash to bring in contractors, document the process and protect output. In both cases, the business survives a blow that might otherwise have been fatal, precisely because money arrives when it is needed most.

Common mistakes when arranging cover

A few avoidable errors undermine otherwise sensible policies.

• Under-insuring by guessing a round number rather than calculating the real financial impact.
• Forgetting guaranteed debt, so the payout cannot clear loans the person backed.
• Ignoring tax, which can shrink a taxable payout below what the business needs.
• Setting the policy up incorrectly, with the wrong owner or beneficiary.
• Reviewing it never, so cover drifts out of step as the business grows.

Each is easily fixed with the right advice. Sizing cover carefully, accounting for tax and debt, and reviewing the policy as the business changes keeps the protection genuinely useful rather than a comforting but inadequate figure on paper. Because the tax position directly affects how much cover you actually need, it is worth reading alongside our guide to keyman insurance tax.

When should you review your cover?

Key person insurance is not a set-and-forget purchase. The right level of cover when you arrange a policy can quickly become too little as the business grows. A sensible habit is to review it at least once a year, and whenever something significant changes.

Trigger points include a jump in turnover or profit, taking on new business borrowing that a key person guarantees, bringing in or losing a key individual, or a change in company structure. Each of these can shift who your key people are and how much they are worth to the business. A policy sized three years ago against a smaller, simpler company may leave a serious gap today. Reviewing cover alongside your annual accounts is an easy way to keep it aligned with reality. It costs nothing to check, and it ensures that if the worst happens, the payout reflects the business you actually run now, not the one you ran when you first signed up.

The bottom line

Key person insurance protects the asset most businesses forget to insure: the handful of people the company truly depends on. For a modest premium, it puts a lump sum in the business exactly when a death or serious illness would otherwise threaten its survival, covering lost profits, recruitment and any guaranteed debt. The keys to getting it right are identifying your genuine key people, sizing cover against their real financial value rather than a guess, factoring in tax, and reviewing the policy as the business grows. Done well, it turns one of the biggest risks a small business faces into a manageable, well-funded setback.
