Life Insurance for Business Owners: Key Man, Shareholder and Director Protection

Personal life insurance protects your family. Business protection insurance protects your company — and, indirectly, your family's financial interest in it. For most owner-directors, the business is their largest single asset. Yet the insurance structures that protect it are frequently absent, inadequate, or incorrectly arranged.

This guide explains the three pillars of business protection: key man insurance, shareholder and partnership protection, and the relevant life plan.

Why Business Protection Is Different

When an individual dies with personal life insurance in place, the path is straightforward: the insurer pays the sum assured, the beneficiaries receive the money, and financial obligations are met. Business protection is more complex because death can trigger multiple simultaneous financial consequences:

• The business loses the skills, relationships, or earning capacity of a key person
• Surviving shareholders or partners face the prospect of the deceased's estate inheriting a share of the business they have no interest in running
• Banks and lenders may call in loans personally guaranteed by the deceased director
• The business may have no immediate liquidity to address any of these challenges

Each of these risks requires a different insurance structure.

Pillar One: Key Man Insurance

Key man (or key person) insurance protects the business against the financial consequences of losing a critical individual — whether through death, or in more sophisticated policies, serious illness.

Who Is a Key Person?

A key person is any individual whose loss would cause the business material financial harm. This may be:

• A founding director whose client relationships underpin the majority of revenue
• A technical specialist (chief engineer, lead developer, head of research) whose expertise is irreplaceable at short notice
• A sales director whose personal network drives new business
• A director who personally guarantees the company's bank facilities

The test is not seniority — it is financial impact. A business should ask: if this person died tomorrow, what would it cost us?

How Key Man Insurance Works

The employer is both the policyholder and the beneficiary. The employer pays the premiums, and the payout goes to the business — not to the key person's family. The funds are then used by the business to absorb the financial impact of the loss:

• Recruitment and onboarding costs for a replacement
• Revenue lost during the period before the replacement becomes fully effective
• Repayment of bank loans that the key person personally guaranteed
• Client retention costs if relationships need to be re-established with a new contact

The sum insured should reflect the realistic financial impact. A common approach is three to five times the key person's annual salary, adjusted for revenue dependency and outstanding business borrowings. Where the key person personally guarantees a bank facility of £500,000, that amount should be included in the calculation.

Tax Treatment of Key Man Insurance

The tax treatment of key man insurance is not straightforward and depends on the purpose of the policy. Where the policy is intended to replace lost revenue (a "revenue purpose"), HMRC's general position is that premiums are deductible against corporation tax and the payout is taxable as trading income. Where the policy is intended to repay a capital loan, HMRC may treat it as a capital arrangement — premiums not deductible, payout not taxable. Specialist tax advice is essential here. We address this in detail in our separate guide on keyperson insurance tax treatment.

Pillar Two: Shareholder Protection

Shareholder protection addresses a specific problem: what happens to the deceased shareholder's stake when they die?

Without a protection plan, the shares pass to the deceased's estate — typically to their spouse or children. This creates a situation where:

• The surviving shareholders are now in business with someone who may have no interest in, or knowledge of, the company
• The estate may want to sell the shares, and the surviving shareholders may have no funds to buy them
• The estate may not want to sell, leaving the business in a permanent state of partial ownership dispute

The result is often damaging to all parties. The estate holds an illiquid asset with no clear exit. The surviving shareholders cannot move the business forward.

The Cross-Option Agreement

The standard solution is a cross-option agreement (also called a double option agreement) combined with life insurance.

Under a cross-option agreement:

• On the death of a shareholder, the surviving shareholders have the option to buy the deceased's shares from the estate
• Simultaneously, the estate has the option to sell the shares to the surviving shareholders

The word "option" is important. Neither party is obligated — they each hold an option. This asymmetry has a specific tax benefit: a cross-option agreement does not create a binding contract of sale, which means it does not trigger a loss of Business Relief for IHT purposes on the deceased's shares.

The purchase is funded by life insurance — typically each shareholder takes out a life policy on the other shareholders, writing the proceeds into trust for the purchasing shareholders. When a shareholder dies, the trust releases the insurance proceeds to the surviving shareholders, who use them to buy the shares from the estate.

Partnership Protection

The same principles apply in a partnership, substituting "partnership share" for "shares". A partnership protection agreement combined with appropriate life insurance allows the surviving partners to acquire the deceased partner's share at an agreed valuation without requiring the partnership to find cash from its own resources.

The valuation methodology — whether based on net asset value, revenue multiple, or EBITDA multiple — should be agreed in advance and written into the protection agreement. Disputes about valuation are the most common source of business protection claims disputes.

Keeping Valuations Current

Business valuations should be reviewed every two years at minimum. A business worth £1 million when the shareholder protection was arranged may be worth £3 million five years later. If the insurance sum assured has not been updated, the surviving shareholders will not have sufficient funds to buy the full shareholding — leaving the estate with a partial stake and a continuing problem.

Pillar Three: The Relevant Life Plan for Directors

For the owner-director who needs personal life insurance, the Relevant Life Plan (RLP) is the most tax-efficient structure available.

How an RLP Works

A Relevant Life Plan is a life insurance policy taken out by the employer on the life of the employee (including directors). The structure is:

• The company pays the premiums — these are a deductible business expense for corporation tax purposes
• The premiums are not a taxable benefit-in-kind for the director — no P11D entry, no income tax, no National Insurance
• The policy is written in trust for the director's family from the outset — the payout goes to the beneficiaries, not to the company
• The payout is outside the director's estate (because the trust owns the policy)
• The cover sits outside the director's registered pension arrangements, so it does not use up pension allowances or interact with the pension lump sum allowances that replaced the lifetime allowance (abolished from 6 April 2024)

For a director who would otherwise pay personally for life insurance from post-tax income, the RLP is significantly more efficient. The company saves corporation tax on the premiums, the director saves income tax and NI on the benefit, and the family receives the payout tax-free in trust.

RLP vs Group Life Insurance

Larger businesses typically provide death-in-service benefits through a group life insurance scheme. For smaller companies with fewer than five employees, setting up a registered group scheme is disproportionately complex. The RLP provides the equivalent benefit for a single director without the regulatory overhead.

The RLP has cover limits — HMRC does not permit the sum assured to exceed a multiple of salary (currently guidance supports up to 30 times earnings). For most directors, this is more than sufficient.

What Happens When the Director Leaves?

If the director leaves the company, the RLP can be converted to a personal policy (a "continuation option") without new medical underwriting in most cases. This is a valuable feature for owner-directors who may exit the business before death occurs.

Structuring Business Protection Correctly

The most common mistakes in business protection are:

Arranging insurance without a legal agreement. A shareholder protection insurance policy without a cross-option agreement provides funds but no mechanism to ensure those funds are used to buy the shares. The surviving shareholders could use the payout for anything — the estate has no contractual right to sell. Both the legal agreement and the insurance must be in place.

Not updating cover as the business grows. The business and shareholder values change. Insurance must be reviewed regularly.

Mixing personal and business purposes. A director who takes out a personal life policy and assigns it to the company creates a complex and potentially inefficient arrangement. Relevant Life Plans are purpose-built for this situation.

Failing to account for all key people. Businesses often insure the majority shareholder but overlook a critical technical director or the sales director who holds the client relationships. A full audit of key person risk is the starting point.
