What Is Key Person Insurance?
Every business relies on certain individuals whose knowledge, relationships or specialist skills are genuinely difficult to replace quickly. When one of these people dies or becomes seriously ill, the impact often extends well beyond the personal loss, potentially threatening revenue, client relationships, lender confidence and the business's ability to continue trading smoothly. Key person insurance, sometimes called key man insurance, is a policy a business takes out to protect itself against this financial impact.
The Business Is the Policyholder
Unlike personal life insurance, key person insurance is owned and paid for by the business itself, with any payout going directly to the business rather than the individual's personal beneficiaries.
What Triggers a Payout
Cover is typically triggered by the death of the insured key person, and many policies can also be structured to include critical illness, providing a payout if the individual becomes seriously ill and unable to continue in their role.
Why This Differs From Personal Life Insurance
Personal life insurance protects an individual's family and dependants; key person insurance protects the business's own financial stability. The underlying insured event may be similar, but the beneficiary, purpose and typical use of the funds are fundamentally different.
Key Terms Explained
- Key Person
- An individual whose loss, through death or critical illness, would cause significant financial disruption to a business.
- Contribution to Profit Method
- A cover calculation approach estimating the key person's direct contribution to business profit.
- Cost of Replacement Method
- A cover calculation approach based on the realistic cost of recruiting and training a suitable replacement.
- Multiple of Salary Method
- A simpler cover calculation approach using a multiple of the key person's salary as a proxy for their value.
- Shareholder Protection Insurance
- A related but distinct policy helping remaining shareholders buy out a deceased or critically ill shareholder's stake.
- Medical Underwriting
- The insurer's health assessment process for the key individual, required for meaningful levels of cover.
Who Counts as a Key Person?
A key person isn't necessarily the most senior individual in a business, but rather whoever's sudden loss would create the most significant financial and operational disruption, whether through lost revenue, damaged client relationships, or a stalled decision-making process.
- Founders and directors with disproportionate knowledge or relationships
- Specialist employees with rare technical expertise
- Top sales or business development individuals
- Anyone whose absence would materially threaten revenue or continuity
Founders and Directors
Founders and directors, particularly in smaller businesses, often hold a genuinely disproportionate share of knowledge about the business's operations, strategy and key relationships, making them common, obvious candidates for key person cover.
Specialist Employees
Beyond formal leadership, employees with rare technical expertise, deep client relationships, or unique institutional knowledge can also represent significant key person risk, even entirely without holding a senior job title.
Top Sales or Business Development Individuals
In some businesses, a single individual's personal relationships and reputation with key clients drive a disproportionate share of revenue, making them a genuine key person risk despite not holding a formal leadership role or an obvious title.
Individuals Providing Personal Loan Guarantees
Where a director or founder has personally guaranteed business lending, their loss can create not just an operational gap but also a direct, immediate financial trigger with lenders, making them an especially high-priority candidate for meaningful, adequately sized key person cover.
Key Person vs Shareholder Protection
| Factor | Key Person Insurance | Shareholder Protection Insurance |
|---|---|---|
| Purpose | Protects the business against financial disruption | Helps remaining shareholders buy out a departing shareholder's stake |
| Who benefits from the payout | The business | Remaining shareholders, or the business under certain structures |
| Typical trigger | Death or critical illness of the key individual | Death or critical illness of a shareholder |
| Common use case | Any critical individual, shareholder or not | Specifically shareholders and business ownership continuity |
Key Person Insurance: Pros
- Provides funds to manage disruption from losing a key individual
- Can reassure lenders and investors of business continuity planning
- Flexible use of payout, from recruitment to covering lost profit
- Can be arranged for any critical individual, not just shareholders
Key Person Insurance: Cons
- Ongoing premium cost for the business
- Requires the key individual's consent and medical disclosure
- Calculating an accurate cover amount can be genuinely complex
- Tax treatment requires professional advice to get right
Businesses Often Need Both
These two products address related but distinct risks, and many businesses with shareholders who are also key operational figures find it worthwhile arranging both types of cover together.
Cover for Different Business Types
Sole Founder Businesses
Where a single founder drives most of the business's strategy, relationships and decision-making, key person cover on that individual is often the single most important piece of business protection insurance a small company can arrange.
Partnerships
In a partnership, each individual partner may represent significant key person risk on their own, and businesses should consider whether cover is genuinely needed on more than one partner rather than simply assuming a single policy covers the whole risk.
Technology and Knowledge-Based Businesses
Businesses built around a specific technical founder or lead engineer often carry concentrated key person risk, since replicating deep technical or product knowledge quickly can be genuinely difficult, particularly for complex or proprietary systems.
Client-Relationship-Driven Businesses
Professional services firms, agencies and consultancies where client relationships are held personally by specific individuals often face acute key person risk, since client loyalty may not automatically transfer smoothly to a new, unfamiliar replacement.
Businesses With External Investment
Investors and lenders often specifically require key person insurance as a condition of funding, since it clearly demonstrates the business has genuinely considered continuity risk around its most critical individuals in advance.
Family Businesses
Family businesses should consider key person cover carefully alongside broader succession planning, since the loss of a family member in a critical operational role can carry both significant financial and emotional complexity simultaneously for everyone involved.
Rapidly Scaling Businesses
As a business scales quickly, key person risk can increase rather than decrease if growth depends heavily on a small founding team, making this a particularly important time to review cover levels carefully and proactively rather than waiting until a formal renewal point arrives.
Businesses Considering a Sale or Exit
Businesses preparing for sale or investment should ensure key person cover is in place and appropriately valued, since buyers and investors often scrutinise continuity risk closely during due diligence, and gaps found late in the process can meaningfully delay or complicate a transaction.
Businesses With International Operations
A key person whose role spans multiple countries or manages international client relationships may carry additional complexity in their replacement cost, since finding someone with equivalent cross-border experience, language skills and established relationships can take considerably longer than a purely domestic hire.
Businesses Reliant on Regulatory or Licensing Expertise
In heavily regulated sectors, a key person holding specific regulatory approvals, licences or compliance knowledge can represent a particularly acute risk, since regulatory requirements may prevent the business from operating certain activities at all until a suitably qualified, formally approved replacement is found and successfully appointed.
Businesses With a Single Major Client Relationship
Where one key individual personally manages the relationship with a client responsible for a large share of revenue, losing that person carries a double risk: the immediate operational gap and the very real possibility the client relationship itself doesn't survive the transition intact.
Nonprofit and Charitable Organisations
Charities and nonprofits led by a small number of individuals with deep sector relationships, donor trust and institutional knowledge can face similar key person risk to commercial businesses, even though the financial impact may manifest as reduced fundraising, weaker grant applications or disrupted programme delivery rather than lost profit in the traditional commercial sense.
What Affects the Cost
- Age and health of the key individual
- Level of cover requested
- Whether critical illness is included
- Policy term length
- Occupation and lifestyle factors
Age and Health of the Key Individual
As with personal life insurance, the age and health of the person being insured significantly affects premium cost, with medical underwriting typically required for meaningful cover amounts.
Level of Cover Requested
Higher cover amounts naturally result in higher premiums, making an accurate, well-considered cover calculation important both for adequate protection and reasonable cost.
Whether Critical Illness Is Included
Including critical illness cover alongside death cover typically increases the premium compared with a death-only policy, reflecting the broader scope of protection provided.
Policy Term Length
Longer policy terms generally involve higher cumulative premium cost, though matching the term to a realistic period of key person risk, such as until a planned succession point, helps keep cost proportionate.
Occupation and Lifestyle Factors
Higher-risk occupations, hobbies or lifestyle factors relevant to the key individual can influence premium pricing in a similar way to personal life insurance underwriting.
Number of Key People Insured
Businesses insuring several key individuals simultaneously may find some insurers offer more favourable overall terms compared with arranging multiple entirely separate policies with different providers over time.
Business Sector and Risk Profile
The nature of the business itself, including its sector, financial stability and growth trajectory, can factor into how an insurer prices and underwrites a key person application, alongside the individual's own personal health and risk factors.
Waiting Periods for Critical Illness Cover
Where critical illness cover is included, the specific conditions covered and any waiting periods before a claim becomes eligible can affect both the premium charged and the practical value of the cover during the early years of the policy.
How to Arrange Cover
A structured approach helps businesses arrange appropriate, well-considered key person cover:
- Identify which individuals, if lost, would create significant financial or operational disruption.
- Calculate an appropriate cover amount using contribution to profit, replacement cost and salary multiple methods.
- Compare the results and arrive at a considered final figure.
- Seek professional financial and tax advice on structuring the policy correctly.
- Obtain the key individual's consent and complete medical underwriting.
Document the Rationale Behind the Cover Amount
Keeping a clear written record of how the cover figure was originally calculated, including which specific methods were used and why, can be genuinely valuable years later, both for internal reference and if the calculation is ever questioned at claim stage.
Communicate the Decision Appropriately
Depending on the business's structure and culture, it may be genuinely appropriate to inform other directors, senior staff or investors that key person cover is now in place, reinforcing confidence in the business's overall approach to continuity planning.
Reviewing Cover as Your Business Changes
Key person insurance shouldn't be treated as a one-off arrangement set up once and forgotten, since the underlying risk it addresses tends to evolve as the business grows and changes.
Growth Can Increase the Financial Stakes
As a business grows, the financial impact of losing a key individual often grows alongside it, meaning a cover amount that was appropriate at an earlier, smaller stage may no longer adequately reflect the current scale of risk.
New Key People May Emerge
As businesses hire and develop talent over time, new individuals may come to hold genuinely critical knowledge, relationships or capability, meaning the original list of insured key people may need to expand.
Sensible Review Points
Reviewing key person cover at significant milestones, such as major growth phases, new senior hires, changes in business structure, or simply every few years as a matter of routine, helps ensure the protection in place continues to reflect genuine current risk.
Review After a Near-Miss
If a key individual experiences a health scare or a near-miss incident that didn't ultimately result in a claim, this can be a genuinely useful prompt to revisit whether the current cover amount and structure still reflect the business's true exposure.
Review Following an Acquisition or Merger
Businesses that acquire another company or merge with one should review key person cover across the whole combined organisation, since new critical individuals may have joined and existing risk profiles may have shifted quite considerably as a result.
Regulation and Tax Treatment
UK business insurers offering key person cover are regulated by the Financial Conduct Authority, which requires fair treatment of business customers and clear policy communication.
Premium Deductibility
Whether premiums are treated as a deductible business expense depends on factors including the policy's purpose and structure, so this shouldn't be assumed without specific professional advice.
Payout Tax Treatment
Similarly, whether a payout is treated as a taxable trading receipt depends on the specific circumstances and structure of the policy, making professional tax advice an important part of arranging key person cover correctly.
Insurance Act 2015 Duty of Fair Presentation
As a commercial insurance product, key person insurance is subject to the Insurance Act 2015 duty of fair presentation, requiring the business to disclose material information about the key individual and the business's circumstances clearly and accurately.
Ongoing Disclosure Duty
If the key individual's health, role or the business's own circumstances change materially during the policy term, the business generally has an ongoing duty to inform the insurer, similar to disclosure obligations that apply under other commercial insurance products.
Data Protection
Insurers must handle the key individual's medical and personal data in line with UK data protection law, and businesses should ensure the individual clearly understands how their data will be used and stored as part of the underwriting and any future claims process.
Choosing an Insurer or Adviser
Work With a Business Protection Specialist
Given the genuine tax complexity involved, work closely with a qualified financial adviser or broker experienced in business protection insurance, alongside your own accountant, to structure the policy appropriately from the outset.
Compare Underwriting Approaches
Insurers vary considerably in how they underwrite key person applications, particularly for individuals with existing health conditions, so comparing more than one provider can be genuinely worthwhile for borderline cases.
Check Claims Handling Reputation
An insurer's reputation for handling business protection claims efficiently matters a great deal given the practical urgency a business often faces after losing a genuinely key individual.
Financial Strength and Longevity
Considering how long an insurer has operated specifically in the UK business protection market offers useful reassurance for a policy the business may hold for many years to come.
Broker Access to Specialist Underwriters
A broker with genuine experience in business protection insurance can often source more favourable underwriting terms than approaching a single insurer directly, particularly for key individuals with existing health conditions, unusual occupations or complex international roles.
Support for Multiple Policies Across a Group
Businesses with several subsidiaries or a wider corporate group structure may benefit from an insurer able to coordinate multiple key person policies consistently across the group, rather than managing entirely separate arrangements with different terms and renewal dates.
Clarity on Policy Documentation
Choose an insurer or adviser who provides clear, accessible documentation of how the policy is structured, since this becomes particularly important years later when a claim may genuinely need to be made under significant time pressure and emotional strain.
Real-World Examples
Case Study: Sole Founder Cover Supports Transition
A small consultancy's sole founder passed away unexpectedly, and the key person insurance payout funded an interim managing consultant and client retention efforts during a difficult transition, preserving much of the firm's client base.
Case Study: Lender-Required Cover
A growing business seeking a substantial loan was required by its lender to arrange key person insurance on its founding director as a condition of finance, illustrating how this cover can directly support access to funding.
Case Study: Critical Illness Claim
A specialist engineer central to a manufacturing business's product development was diagnosed with a serious illness, and the business's critical illness-inclusive key person policy provided funds to bring in specialist contract support during recovery.
Case Study: Cover Recalculated After Growth
A business that had significantly grown since its original key person policy was arranged reviewed and increased cover to reflect the founder's now much larger contribution to profit, avoiding a potential underinsurance gap.
Case Study: Regulatory Expertise Gap
A financial services firm's compliance director, holding specific regulatory approvals, became critically ill, and the resulting key person payout funded both interim compliance support and the extended recruitment process needed to find and get a suitably qualified replacement approved by the regulator.
Case Study: Major Client Relationship Preserved
An agency's business development director, who personally managed the firm's largest client account, passed away suddenly. The key person payout funded a structured client transition plan and additional relationship management support, helping preserve the account through a difficult period.
Case Study: Due Diligence Requirement Met
A business seeking acquisition by a larger group found that key person insurance on its founding directors, already in place, satisfied a specific due diligence requirement raised by the acquiring company, helping the transaction proceed without delay.
Making a Claim
Making a key person insurance claim generally follows a structured process once the insured event occurs.
- Notify the insurer promptly once the death or critical illness diagnosis has occurred.
- Provide required documentation, such as a death certificate or medical evidence of critical illness.
- Confirm the original policy terms and disclosed information align with the circumstances of the claim.
- Work with the insurer's claims team throughout the assessment process.
- Once approved, direct the payout toward the business's identified priorities, such as recruitment or covering lost profit.
Working With Professional Advisers During a Claim
Involving your accountant or financial adviser during the claims process can help ensure the payout is used and accounted for appropriately, particularly given the tax considerations involved.
Communicating With Stakeholders During a Claim
Alongside the practical claims process, businesses often need to communicate sensitively with employees, clients and lenders about the loss of a key individual, and having a payout confirmed or genuinely in progress can materially strengthen these difficult conversations by demonstrating real financial resilience.
Documentation Typically Required
Insurers typically require a certified death certificate for a death claim, or detailed medical evidence and specialist consultant reports for a critical illness claim, alongside confirmation of the original policy application and any relevant supporting business records.
Common Mistakes to Avoid
- Assuming a single job title, rather than actual business impact, identifies all key people.
- Relying on only one cover calculation method without comparing approaches.
- Not seeking professional tax advice before assuming premium deductibility.
- Failing to review cover as the business grows or changes structure.
- Overlooking new key people who emerge as the business develops.
- Not obtaining the key individual's consent early in the process.
- Confusing key person insurance with shareholder protection insurance.
- Letting cover lapse without review after a key person leaves the business.
- Underestimating the replacement cost for roles requiring specific regulatory approvals.
- Failing to document how the cover amount was calculated for future reference.
Common Myths
- Myth: Key person insurance only makes sense for large companies. Small businesses are often more exposed to this risk proportionally.
- Myth: The payout automatically goes to the key person's family. The business itself owns the policy and receives any payout.
- Myth: Key person insurance and shareholder protection are the same thing. They address related but genuinely distinct risks.
- Myth: Premiums are always tax deductible. Tax treatment depends heavily on the policy's specific structure and purpose.
- Myth: Only the CEO or founder can be a key person. Specialist employees and top sales individuals can represent equally significant risk.
- Myth: Key person cover doesn't need reviewing once arranged. Business growth and structural change can make original cover levels outdated.
- Myth: A single flat multiple of salary is always the right cover figure. This method often understates true value for relationship-driven or regulatory-critical roles.
- Myth: Nonprofits and charities don't face key person risk. Organisations reliant on a small number of leaders with donor and sector relationships face very similar exposure.
Frequently Asked Questions About Key Person Insurance
What is key person insurance?
Key person insurance is a policy taken out by a business on the life, and sometimes health, of an individual whose skills, knowledge or relationships are considered critical to the business's ongoing success.
Who owns a key person insurance policy?
The business itself typically owns and pays for the policy, and any payout goes to the business rather than the key individual's personal beneficiaries, distinguishing it from personal life insurance.
How much key person insurance cover does a business need?
This depends on the specific financial impact the loss of that individual would have, commonly estimated using methods based on their contribution to profit, the cost of replacing them, or a multiple of their salary.
Is key person insurance tax deductible for a business?
Tax treatment depends on the specific structure and purpose of the policy, and can vary, so businesses should seek professional tax advice specific to their circumstances rather than assuming a blanket treatment applies.
Can a small business benefit from key person insurance?
Yes, small businesses are often more exposed to key person risk than larger organisations, since a single founder or specialist employee may represent a disproportionately large share of the business's knowledge, relationships or capability.
Does key person insurance cover critical illness as well as death?
Many key person policies can be arranged to cover critical illness in addition to death, or as a standalone critical illness benefit, depending on the specific risks the business wants to protect against.
How is key person insurance different from shareholder protection insurance?
Key person insurance protects the business against the financial impact of losing a critical individual, while shareholder protection insurance specifically helps remaining shareholders buy out a deceased or critically ill shareholder's stake.
Does the key person need to consent to being insured?
Yes, the individual must consent to being insured and typically needs to undergo medical underwriting, since the policy relates directly to their life and health.
Can a business insure more than one key person?
Yes, businesses can arrange separate key person policies for multiple critical individuals, each calculated according to their specific contribution and replacement cost.
What happens to a key person policy if the individual leaves the business?
If the key person leaves, the policy generally needs to be reviewed, since it was arranged specifically around their role; the business may cancel, reassign or restructure cover depending on circumstances.
Does key person insurance cover redundancy or resignation?
No, key person insurance is designed to respond to death or critical illness, not voluntary resignation or redundancy, which fall outside what this type of policy is intended to address.
How quickly does a key person insurance payout arrive?
Once a valid claim is submitted with the required documentation, payouts are often processed within a matter of weeks, though this varies by insurer and the complexity of the claim.
Can key person insurance be written in trust?
Key person insurance is typically owned directly by the business rather than written in trust, unlike some forms of personal life insurance, though specific structuring should be discussed with a professional adviser.
Does key person insurance affect the individual's personal life insurance?
No, key person insurance is separate from any personal life insurance the individual holds privately, and having one does not typically affect eligibility for the other.
How often should a business review its key person insurance?
Reviewing at significant milestones, such as business growth, new senior hires or changes in structure, and at least every few years as routine practice, helps ensure cover remains appropriate.
What should a business do if a key person insurance claim is declined?
Request a written explanation, check it against the policy wording and original disclosure, and if unresolved you can escalate through the insurer's complaints process and then to the Financial Ombudsman Service where eligible.
If Something Goes Wrong
If a business is unhappy with how a key person claim or policy has been handled, raise a formal complaint with the insurer first and keep a clear written record of all correspondence, including original disclosure documentation.
Escalating to the Financial Ombudsman Service
Smaller businesses may be eligible to refer an unresolved complaint to the Financial Ombudsman Service free of charge if it's not resolved within eight weeks or a final response is disputed, subject to the Ombudsman's business eligibility criteria.
Disputes Over Disclosure or Underwriting
If an insurer disputes information disclosed about the business or key individual at application, gather all original application records and any relevant adviser correspondence to support your position during any dispute.
Disputes Over Claim Valuation
If a business disagrees with how a critical illness claim has been assessed against the policy's specific medical definitions, request the underlying clinical criteria used and, where appropriate, seek a genuinely independent medical opinion to support the case for reassessment.

Conclusion
Key person insurance addresses a risk that many businesses, particularly smaller ones, underestimate until it's too late: the genuine financial disruption that can follow the loss of a critical individual. By identifying key people honestly, calculating a considered cover amount, and structuring the policy correctly with professional advice, businesses can build meaningful protection against one of the more overlooked risks in business continuity planning.
If your business relies heavily on the knowledge, relationships or skills of a small number of individuals, it's worth taking the time to assess this risk properly rather than assuming it won't materialise. The relatively modest ongoing cost of key person insurance is, for many businesses, a reasonable price for genuine financial resilience.
