What is Key Person Insurance and How Does it Protect a Business?
June 26, 2026
Key person insurance is a policy taken out by a business to protect itself if someone essential to the business dies or becomes seriously ill.
Unlike personal life insurance, which pays money to the insured person’s family, key person insurance is owned by the business. The business pays the premiums and receives the payout if a valid claim is made.
The purpose of key person insurance is to help the business manage the financial impact of losing someone whose knowledge, relationships or role would be difficult to replace quickly.
What is Key Person Insurance?
Key person insurance is a type of business protection.
It’s usually a life insurance policy, with the option to add critical illness cover. It’s taken out on the life of someone whose death or incapacity could cause significant financial harm to the company.
The basic principle is simple. The business identifies people who are central to its success and insures them. If one of those people dies or suffers a covered serious illness, the business receives a lump sum.
The money can help the company stabilise while it deals with the disruption. It may be used to:
- repay business borrowing
- replacing lost income
- funding recruitment
- paying for temporary support
- training a replacement
- supporting cash flow
- giving the company time to restructure
Key person insurance isn’t a legal requirement in the UK. However, it can be an important risk management tool for businesses that rely heavily on one or a small number of people.

Who Can be Covered by Key Person Insurance?
A key person is someone whose loss would have a serious effect on the business.
HMRC doesn’t provide a precise statutory definition, but the working definition is someone whose death or disability would have a serious effect on the company’s future profits.
A key person doesn’t have to be a shareholder. A non-shareholding employee could be a key person if their skills, knowledge or relationships are difficult to replace.
Examples may include:
- a founder or business owner
- a managing director or chief executive
- a senior salesperson
- a technical specialist
- an operations manager
- a financial controller or finance director
- a key account manager with important client relationships
A business can take out more than one key person policy where several people are important to its financial stability.
How Does Key Person Insurance Work?
Key person insurance is arranged by the business.
The business chooses the person to insure, applies for the policy, pays the premiums and is normally the sole named beneficiary. The key person must give written consent before the business can take out cover on their life.
The policy is usually written for a fixed term, such as five, 10 or 15 years. The term should reflect the period of risk – for example, the length of a business loan, the expected time the key person will remain important to the company or the period during which the business would be most exposed to their death or critical illness (if included).
If the insured person dies or suffers a covered critical illness during the policy term, the business makes a claim. If the claim is accepted, the insurer pays the lump sum directly to the business.
The business can then use the money to support trading, meet costs or manage the transition. There is no requirement to place the policy in trust because the intended recipient is the business itself.
What Does Key Person Insurance Cover?
The core cover is usually life insurance which means the policy pays out if the key person dies during the policy term. Terminal illness cover can be included. This may allow the policy to pay out early if the person is diagnosed with a terminal condition and is expected to die within 12 months.
Critical illness cover can also often be added. This may provide a payout if the key person is diagnosed with a specified serious condition. Common examples include cancer, heart attack, stroke or multiple sclerosis, although the exact conditions covered depend on the insurer.
Some providers also offer income protection-style cover. This pays regular monthly benefits if the key person is temporarily unable to work due to illness or injury. This is less common than lump sum cover, but may be relevant where temporary absence is the main risk.
Key person insurance doesn’t cover someone resigning, retiring or being made redundant. It also doesn’t cover poor business performance that’s unrelated to the key person’s death or illness.
Why do Businesses Take Out Key Person Insurance?
A business may need key person insurance where one person’s absence could cause a financial problem.
This can be especially relevant for small and medium-sized businesses. In some companies, one person may be responsible for a large share of revenue, client relationships, technical knowledge or day-to-day continuity.
If that person dies or becomes seriously ill, the business may need time and money to adjust. It will likely have to recruit, train a replacement, bring in temporary support or manage delays in delivering work.
There may also be pressure from lenders. A bank or financial institution may require key person insurance where a business loan depends on the involvement of one or more individuals. In some cases, the policy may be assigned to the lender, so any claim proceeds are used to repay the outstanding balance first.
Key person insurance can also be structured to cover business loans, director’s loan accounts or personally guaranteed borrowing, depending on how the policy is arranged.
How Much Key Person Insurance Cover Does a Business Need?
The amount of cover should reflect the financial impact the business could face if the key person were lost.
There are two common ways to estimate the level of cover:
- One method is to use a salary multiple. A business may multiply the key person’s annual salary by the number of years it expects recovery to take. Industry guides commonly suggest up to around 10 times annual salary as a benchmark ceiling for life cover, and up to around five times salary for critical illness cover, though figures vary between insurers and advisers.
- Another method is to look at profit contribution. This considers the key person’s direct contribution to profit and multiplies it by the expected recovery period. Recruitment costs, training costs and business debts may also be included.
Is Key Person Insurance Tax-deductible?
The tax treatment of key person insurance in the UK depends on the purpose of the policy.
Tax treatment follows the purpose of the policy. Premiums may be deductible as a trading expense where the sole purpose of the policy is to cover a potential loss of trading income from the loss of the key person’s services.
Other conditions also need to be met. These include:
- the policy term not extending beyond the key person’s period of usefulness to the company
- a genuine employer and employee relationship
- the cover not being mainly there to protect a major shareholder’s share value, as HMRC may view this as a non-trade purpose even where an employment relationship exists
- the policy being pure protection with no investment element
Where premiums are deductible, any payout received by the business is treated as a trading receipt and subject to corporation tax.
Where the policy has a capital purpose, premiums aren’t deductible. Examples of this include:
- protecting the capital value of the business
- covering ownership interests
- repaying a business loan
In these cases, proceeds aren’t taxed as trading income.
Businesses should take tax advice before assuming how premiums or payouts will be treated.
Key Person Insurance vs Shareholder Protection
Key person insurance and shareholder protection are different.
Key person insurance protects the business from the financial impact of losing an important person. The business owns the policy and receives the payout.
Shareholder protection is designed to help surviving shareholders buy the shares of a shareholder who dies or becomes seriously ill, depending on the arrangement. Unlike key person insurance, it’s usually the individual shareholders – not the business – who own the policies and receive the payout, typically under a cross-option agreement that gives surviving shareholders the right to buy the shares and the deceased’s estate the right to sell. The purpose is ownership continuity, rather than protecting trading income.
The distinction matters because the policy owner, beneficiary, purpose and tax treatment are different.
Key Person Insurance vs Relevant Life Cover
Key person insurance also differs from relevant life cover.
Key person insurance protects the business. The business receives the payout and uses it to manage the financial impact of losing the insured person.
A relevant life policy is usually an employee benefit. It’s designed to provide a death in service-style payout to the insured person’s family or dependants. It requires a genuine employer/employee relationship, so shareholders who aren’t also employees of the company (including most sole traders and partners) usually can’t be covered this way, and it can’t be used to fund a key person or share purchase need.
The main difference is who the policy is designed to protect. Key person insurance protects the company. Relevant life cover protects the individual’s beneficiaries.
What to Consider Before Taking Key Person Insurance
Before taking key person insurance, a business should identify who it relies on most and what would happen if that person could no longer work. It should also consider what financial loss might arise, how long recovery could take and whether the policy should protect profits, business loans or another specific risk.
The purpose of the policy should be documented clearly. This is important for tax treatment and for showing why the cover was taken out.
Cover should also be reviewed regularly. A policy that was suitable when it started may become too low if the business grows. It may also change if the business takes on new borrowing or the key person’s role changes.

Important information
The suitability of Key Person Insurance and Shareholder Protection will depend on a business’s circumstances. Policy terms, exclusions and tax treatment vary and can change over time. Note that life insurance and financial protection plans typically have no cash in value at any time and cover will cease at the end of the term. If premiums stop, then cover will lapse. Life insurance products vary, and suitability depends on individual circumstances. Always seek advice from a qualified professional before making any decisions.
