- Age, health and lifestyle are the biggest drivers of the premium.
- Adding critical illness cover to life cover typically increases the cost.
- The sum assured and term length scale the premium up or down.

Understanding keyman insurance cost is the first question most business owners ask once they decide they need cover. The honest answer is that it varies widely, because the premium is built around the individual being insured and the protection the business wants. This guide explains exactly what drives the price, gives realistic example ranges and shows how to keep the cost down without weakening your protection.

What drives the cost of keyman insurance?
Keyman insurance is priced like any life or illness policy: the insurer estimates the risk and charges accordingly. The premium reflects how likely a claim is and how large it would be.
The main factors that set your premium are:
- Age of the key person, the single biggest driver.
- Health and medical history, including any ongoing conditions.
- Lifestyle, such as smoking, which can sharply raise the cost.
- Sum assured, the amount the business wants to insure.
- Policy term, the number of years the cover runs.
- Cover type, life only or life plus critical illness.
No two quotes are identical because no two people are. A 35-year-old non-smoker in good health will pay a fraction of what a 58-year-old smoker pays for the same sum assured.
Why age matters most
Age is the dominant factor because risk rises steadily over time. Insuring someone in their thirties is far cheaper than insuring the same person in their fifties.
This is why many businesses arrange cover early and lock in a rate while the key person is younger. Waiting often means paying more for the same protection later.
How the sum assured affects the premium
The sum assured is the amount the policy pays out, and it scales the premium directly. Doubling the cover roughly doubles the base cost, all else being equal.
Setting the right figure matters. Businesses often base it on the financial impact of losing the person, such as lost profit, the cost of recruiting and training a replacement, or any loan the person guarantees.
Over-insuring wastes money, while under-insuring leaves a gap when it matters most. A sensible sum assured is large enough to protect the business but no larger than the genuine exposure, which keeps the premium proportionate.
Life cover vs critical illness cover
The type of cover you choose has a real effect on price. Life-only cover pays out on death or terminal illness, while adding critical illness cover means the policy can also pay if the key person survives a serious illness such as cancer, a heart attack or a stroke.
Critical illness cover increases the premium because claims are more likely than death claims during a working lifetime. Many businesses still choose it, because a key person being unable to work for months can hurt the business as much as their death.
The right balance depends on what you are protecting against. If your main concern is debt repayment on death, life-only cover may be enough. If you are protecting against the loss of someone’s day-to-day contribution, combined cover is worth the extra cost.
Realistic keyman insurance cost examples
Exact prices need a quote, but illustrative ranges help set expectations. The figures below are broad guides for healthy non-smokers and will vary by insurer and circumstances.
- Age 30, £250,000 life only, 10-year term: often around £15 to £30 a month.
- Age 40, £500,000 life only, 10-year term: commonly around £30 to £70 a month.
- Age 50, £500,000 life only, 10-year term: typically £80 to £160 a month or more.
- Adding critical illness cover: can increase the premium by roughly two to three times.
These ranges are indicative only and should not be taken as a quote. Smoking, health conditions, a longer term or a larger sum assured can all move the figure significantly. The only reliable number comes from a personalised illustration.
It also helps to think in terms of cost per £100,000 of cover rather than a single headline figure. Pricing is broadly proportional, so once you know the rate for a given person and term, you can scale it up or down to test different levels of protection. That makes it easier to find the point where the cover is adequate and the premium still comfortable.
Why your quote may differ
Two businesses insuring people of the same age can receive very different quotes. Medical history, occupation, hobbies and even build can all affect underwriting.
Some applications are accepted at standard rates, while others carry a loading or require further medical evidence. This is normal, and a broker can help place the cover with the insurer most likely to offer a competitive rate for your situation.
How the policy term changes the cost
The term is the number of years the cover runs, and it has a clear effect on the premium. A longer term means more years of risk for the insurer, so it usually costs more each month than a shorter one.
Most keyman policies are term assurance, set to match a specific need. Common choices include:
- Matching a loan, so the cover lasts exactly as long as the debt.
- Matching a project or contract, where the key person is central to delivery.
- A rolling business term, reviewed every five or ten years.
Choosing a term that fits the genuine need avoids paying for cover you do not require. A ten-year loan does not need a twenty-five-year policy, and trimming the term where it is sensible keeps the premium down.
Level, decreasing and increasing cover
How the sum assured behaves over the term also affects price. Level cover keeps the payout the same throughout, while decreasing cover reduces it over time, often to track a repaying loan.
Decreasing cover is usually cheaper than level cover, because the insurer’s exposure falls each year. Increasing cover, which rises to keep pace with inflation or a growing business, costs more. Matching the shape of the cover to what you are protecting helps you avoid overpaying.
Who pays the premium and how cover is set up
For keyman insurance, the business usually owns the policy, pays the premiums and receives any payout. This company ownership is what defines it as business protection rather than personal cover.
The way the policy is arranged affects both the tax position and the cost-effectiveness of the cover. A policy set up correctly as business protection, on the life of an employee or director, is the arrangement most likely to qualify for favourable treatment.
Getting the ownership and purpose right from the start matters. A poorly structured policy can cost the same in premium but deliver a worse outcome at claim time, so it is worth setting it up properly with proper advice.
How to keep keyman insurance costs down
There are practical ways to reduce the premium without leaving the business exposed. Small choices add up over the life of the policy.
Sensible ways to control the cost include:
- Insure the right amount, based on real exposure rather than a round number.
- Match the term to the need, such as the length of a loan or a key project.
- Arrange cover early, while the key person is younger and healthier.
- Review cover periodically, adjusting as the business and the risk change.
- Compare the market, since premiums for identical cover vary between insurers.
Cutting cover too far is a false economy. The aim is to pay a fair price for the protection you genuinely need, not the cheapest premium for cover that falls short.
Does the tax treatment affect the real cost?
The after-tax cost can differ from the headline premium, which is why tax treatment is part of the cost conversation. The general position is that premiums may be tax-deductible under what are known as the Anderson principles, subject to your local inspector’s agreement.
In broad terms, relief is more likely where the policy covers an employee, runs for a short term, and exists wholly to protect the business against loss of profits rather than as a benefit to the individual. Where premiums are allowed as a business expense, any payout is usually treated as a trading receipt and taxed.
The treatment depends entirely on the specific arrangement and the inspector’s view, so nothing here is guaranteed. Our detailed guide to keyman insurance and tax explains the Anderson principles in full, and you should confirm your own position with an accountant.
When you compare quotes, it is worth asking your accountant whether relief is likely in your case, because it can change which option offers the best value after tax. A slightly higher premium with relief available may work out cheaper than a lower one without it, so the headline figure does not always tell the whole story.
Is keyman insurance worth the cost?
Cost only makes sense alongside value. The question is not simply how much the premium is, but what the business stands to lose without the cover.
For many businesses, the monthly premium is small compared with the financial shock of losing a founder, top salesperson or technical lead. A payout can fund recruitment, cover lost profit, reassure lenders and buy the business time to recover.
It can also protect relationships that the business depends on. Lenders, investors and major customers all take comfort from knowing a business is insured against losing the person who drives it. In that sense the cover does quiet work long before any claim, supporting confidence in the business as a whole.
Weighing the premium against that exposure usually reframes the decision. A few tens of pounds a month to protect against a six-figure loss is, for most businesses, a sensible trade. The right level of cover is the one that matches your genuine risk.
Common mistakes that push the cost up
Businesses often pay more than they need to, not because cover is expensive, but because of avoidable errors in how they buy it. Knowing these in advance helps you sidestep them.
- Leaving it late, so the key person is older and the premium higher.
- Insuring a round number rather than the real financial exposure.
- Buying the first quote without comparing the wider market.
- Choosing a longer term than the need, paying for unused years.
- Adding benefits that are not required, inflating the monthly cost.
Each of these is easy to fix before you commit. A short conversation about what you are genuinely protecting, and for how long, usually produces a leaner, fairer premium than buying cover off the shelf.
How keyman cost compares with other protection
Keyman insurance is one of several business protection products, and its cost should be seen in that context. Different products protect against different risks, and the right mix depends on your business.
Where keyman insurance protects the business against losing a key individual, other products protect ownership or borrowing. Shareholder protection funds a share buyout if an owner dies, while business loan protection clears borrowing if a guarantor dies or falls critically ill.
Because each serves a distinct purpose, comparing them on premium alone is misleading. A business may sensibly hold more than one, and the combined cost is still small against the risks they cover. Looking at protection as a package, rather than line by line, gives a truer picture of value.
What you need for an accurate quote
Because the premium is built around the individual, a meaningful quote needs a few details up front. Gathering these before you ask saves time and produces a figure you can rely on.
An insurer or broker will typically want to know:
- The key person’s age and date of birth, the starting point for pricing.
- Their health and lifestyle, including smoking status and any conditions.
- The sum assured you want, based on the business’s exposure.
- The term, often tied to a loan, contract or planning horizon.
- The cover type, life only or life plus critical illness.
With those details, a broker can return realistic figures quickly and place the cover with a suitable insurer. Larger sums assured may trigger medical underwriting, which can adjust the final premium, but the initial illustration gives you a solid basis for budgeting.

Frequently Asked Questions
It varies widely with age, health, sum assured, term and cover type. As a rough guide, a healthy person in their thirties might pay from around £15 to £30 a month for £250,000 of life-only cover, with costs rising for older people, larger sums or added critical illness cover. A personalised quote is the only accurate figure.
Older age, smoking, health conditions, a high sum assured, a long term and adding critical illness cover all push the premium up. Age and health tend to have the biggest effect, which is why arranging cover earlier usually costs less.
Life-only keyman cover is generally cheaper than cover that also includes critical illness. Adding critical illness can increase the premium by roughly two to three times, because the insurer is more likely to pay out during the person’s working life.
Businesses usually base it on the financial impact of losing the person, such as lost profit, the cost of finding and training a replacement, or any loan they guarantee. The aim is a figure that covers the genuine exposure without over-insuring, which keeps the premium proportionate.
Yes. Insuring the right amount, matching the term to the need, arranging cover while the key person is younger and comparing the whole market all help. Cutting cover too far is a false economy, so the goal is a fair price for the protection you genuinely need.
It can. Premiums may be tax-deductible under the Anderson principles, subject to your local inspector’s agreement, which reduces the after-tax cost. Where premiums are allowed as a business expense, any payout is usually taxed as a trading receipt, so confirm your position with an accountant.
