Key person insurance, sometimes referred to as key man insurance, is a life and critical illness policy taken out by a business on the life of an individual whose skills, client relationships, technical expertise, or leadership are essential to the financial performance of the company. The business is the policyholder, pays the premium, and receives the payout on the key person's death or diagnosis of a qualifying critical illness. The funds protect the business against the financial consequences of that person's sudden absence: lost revenue, the cost of recruiting and integrating a replacement, the impact on client confidence, and the potential recall of credit facilities secured against a personal guarantee. At Vsure Financial, we advise businesses of all sizes on identifying who qualifies as a key person, calculating the appropriate sum insured, and structuring the policy correctly for both financial protection and tax efficiency.
The death or serious illness of a key individual in a small business is not a theoretical risk. It happens regularly across businesses of all sizes, and the financial consequences are consistently underestimated by the owners of those businesses. Lost revenue, a disrupted client relationship, and the cost of recruiting and integrating a replacement can run to hundreds of thousands of pounds, at a time when the business is already under significant operational and emotional pressure. Key person insurance is one of the most cost-effective ways to protect against this specific and predictable risk.
Your complete guide to Key Person Insurance
Who qualifies as a key person
A key person is defined not by their job title but by the financial impact their absence would have on the business. In a small business, this is often the founder or managing director whose client relationships, industry knowledge, and revenue generation are central to the company's viability. In a professional services firm, it may be a senior fee-earner who generates a significant proportion of annual billings. In a technology business, it might be a technical lead whose expertise underpins a product or platform the company depends on. In any business with personally guaranteed bank debt, it includes every director who has signed a personal guarantee. The test is straightforward: if this individual died or became seriously ill tomorrow, how much would it cost the business in lost revenue, recruitment fees, and management disruption? That calculation is the starting point for determining whether a key person policy is needed and for what sum. Most businesses, when they work through this honestly, find they have more key people and a larger financial exposure than they initially assumed.
How the sum insured is calculated
There is no single formula for calculating the appropriate sum insured for a key person policy, because the financial contribution of a key individual varies by business type, size, and structure. Common approaches include a multiple of the key person's annual remuneration, typically between 3 and 10 times salary, reflecting the cost of replacement and the value lost during a transition period. Where the key person generates a specific and identifiable proportion of the business's gross profit, using a multiple of that profit contribution provides a more accurate measure of the financial exposure. Where the key person has provided a personal guarantee on a business loan or credit facility, the sum insured should at minimum cover the outstanding facility. In some businesses, a combination of approaches is appropriate: a base sum to cover replacement costs and a further amount to protect against lost revenue during the transition period. Your Vsure adviser will model the financial exposure and present a recommended sum insured with a clear rationale, so the level of cover is demonstrably proportionate to the risk.
Tax treatment of key person insurance
The tax treatment of a key person policy depends primarily on its stated purpose. Where the policy is taken out to protect the business against the loss of profit directly attributable to a key person, HMRC's general position is that the premium is an allowable deduction against Corporation Tax and the payout is treated as a trading receipt, subject to Corporation Tax. Where the policy is designed to repay a specific capital liability such as a business loan, the premium may not qualify as a revenue expense and the payout may be treated as capital rather than income. The tax position of key person insurance is not always straightforward, and the precise treatment depends on the specific purpose of the policy, how it is documented, and the accounting approach taken. You should take specialist tax advice alongside the insurance advice. Your Vsure adviser will outline the tax considerations and recommend you discuss the treatment with your accountant before the policy is placed.
Critical illness cover within a key person policy
A key person policy can be structured to pay on death only, or on both death and critical illness. Including critical illness cover extends the protection to the statistically more likely scenario: a key person who survives a serious health event but is unable to work for an extended period, or who is forced to step back from active management of the business before they planned to. Cancer, a cardiac event, or a stroke can render an individual unable to fulfil their role for months or permanently, creating exactly the same financial disruption to the business as a death, while the individual remains alive. The critical illness element covers a defined list of conditions and pays as a lump sum on qualifying diagnosis. For businesses where the key person's continued contribution is as important as their survival, a combined life and critical illness policy provides the most complete protection available.
