Key Person Insurance for Trade Businesses — Protecting Against the Loss of a Key Worker (2026)

What Key Person Insurance Actually Is

Key person insurance — still widely called "keyman" cover in the trade — is a life (and usually critical illness) policy that the business takes out on the life of a key individual. That person might be the owner, a working director, or a vital skilled employee whose absence would seriously damage the company. The business is the policyholder, pays the premiums and is the beneficiary. If the insured person dies or, on a combined policy, is diagnosed with a qualifying critical illness, the lump sum is paid to the company.

That last point is the whole game. The money goes to the business, not to the family. It is there to cover the financial shock of losing the person: lost gross profit while the business recovers, the cost of recruiting and training a replacement, repaying loans or overdrafts that may be called in, and simply keeping the lights on, wages paid and suppliers happy during a difficult period.

It is easy to confuse key person cover with relevant life cover, and the two are often sold side by side, but they do completely different jobs. Relevant life cover is a death-in-service style policy the company pays for, but the payout goes into a trust for the employee's family. Key person cover pays the company. One protects the household; the other protects the business. Many trade firms need both.

Why a Small Trade Business Needs It

In a large company, no single person is irreplaceable overnight. In a small trade business, the opposite is true. Consider what actually happens if the boss is suddenly off long-term or dies:

• Revenue stalls. If one person wins most of the work, prices the jobs and holds the client relationships, the pipeline can dry up within weeks. Quotes don't go out, tenders are missed, and existing clients drift to competitors.
• Skilled output drops. If the key person is the only one who can run a particular type of job — a specialist installation, a regulated trade, complex groundworks — the business may have to turn work away or sub it out at a loss.
• Lenders get nervous. Many business loans, overdrafts and asset finance agreements are granted partly on the strength of the key individual. Some facilities contain clauses allowing the lender to review or recall the debt if that person leaves or dies. A personal guarantee may also crystallise.
• Recruitment costs bite. Replacing a skilled tradesperson or an experienced estimator is expensive and slow. Agency fees, the time to find someone good, and the ramp-up period all cost money the business may not have spare.

A key person payout buys time and breathing space. It lets the surviving owners or directors recruit properly, ride out a slump in trading, and avoid a fire sale or insolvency caused by a temporary — but severe — shock.

How Much Cover Should You Take?

There is no single correct figure, but a few rules of thumb help you land in the right range. The aim is to cover the realistic financial damage, not to over-insure.

• Multiple of profit contribution. A common approach is to take a multiple — often two to five times — of the gross profit the key person directly generates or contributes to. A director who personally brings in £200,000 of gross profit a year might be insured for £400,000–£1,000,000.
• Multiple of salary. A simpler proxy, used for skilled employees, is around 5–10 times the person's annual salary or remuneration. It's rough, but quick.
• Loans plus lost profit during recovery. Add up the business debts that would need clearing or covering if the person went, then add the gross profit you'd expect to lose over the recovery period (typically one to two years). That total is a defensible cover figure.

Whichever method you use, write down the reasoning. Insurers will ask you to justify the sum assured at application stage, and a clear calculation also helps your accountant and any future audit. Review the figure whenever turnover changes materially or you take on new borrowing.

The Tax Treatment — The Anderson Rules

This is where key person cover trips up a lot of trade business owners, so it is worth getting straight. HMRC's long-standing position, set out by the then Financial Secretary in 1944 and known as the "Anderson rules", governs whether the premiums your company pays are an allowable deduction for corporation tax.

Broadly, premiums may be tax-deductible when all of these conditions are met:

• The sole purpose of the policy is to meet a loss of trading income resulting from the loss of the key person — not to cover a capital loss or to protect a loan.
• The insured person is an employee (which can include a working director) and not a substantial shareholder — HMRC generally treats a holding of more than around 5% as substantial.
• The policy is short-term — a term assurance policy roughly matching the period the person is expected to be a key employee, with no investment or surrender value.

Where those conditions are satisfied and the premiums are allowed against corporation tax, the flip side applies: any payout is generally treated as a taxable trading receipt. You get tax relief on the way in, but the lump sum is taxed when it arrives.

Where the conditions are not met — for example the policy insures a major shareholder, runs for a long term, or exists to repay a capital loan rather than replace trading income — the premiums are usually not deductible. In that case the payout is often not taxable in the company's hands. The two outcomes tend to mirror each other: relief in, tax out; no relief in, no tax out.

Crucially, this is decided case by case. HMRC does not give blanket pre-approval, and the local inspector takes the final view based on the facts of your specific policy. Do not assume your premiums are deductible just because a broker mentioned it might be possible. Confirm the treatment in writing with your accountant, and where there is any doubt over a significant policy, your accountant can seek clearance or clarification from HMRC. Budget on the basis that the tax position is uncertain until confirmed.

Business Loan Protection — A Related Use

A close cousin of key person cover is business loan protection. Here the policy is written specifically to clear a defined debt — a director's loan, a commercial mortgage, asset finance on plant and vehicles, or a bank overdraft — if the key person dies or becomes critically ill. The cover amount tracks the outstanding balance, and the payout is used to repay the lender.

Because loan protection is about meeting a capital liability rather than replacing trading income, it typically falls outside the Anderson conditions, so the premiums are usually not corporation-tax deductible and the payout is usually not taxable. If you have personal guarantees against company borrowing, loan protection can be especially valuable — it stops the lender pursuing the deceased person's estate or the surviving directors. Keep loan protection as a separate, clearly purposed policy rather than blurring it into a general key person plan; it makes the tax position cleaner and the claim simpler.

Worked Example: A Two-Director Groundworks Company

Take a small groundworks limited company with two directors. Dave runs the machines and the sites; Mark wins the contracts, prices the jobs and holds the relationships with the main contractors who feed them work. Mark is the rainmaker — without him, the order book empties.

The company turns over £900,000 with a gross profit of around £270,000. Mark is directly responsible for winning roughly 80% of the work, so the directors judge that around £215,000 of gross profit each year depends on him. They also have £120,000 of outstanding asset finance on excavators and dumpers, secured in part on Mark's personal guarantee.

They put two policies in place. First, a key person term policy on Mark's life and critical illness for £450,000 — roughly two years' worth of the gross profit he generates, to fund recruitment of an experienced estimator and to keep the business trading while the pipeline is rebuilt. Second, a separate loan protection policy for £120,000 to clear the asset finance and release the personal guarantee if the worst happens.

Because Mark holds 50% of the shares, he is a substantial shareholder, so their accountant advises that the key person premiums are unlikely to be deductible — and, correspondingly, that a payout would probably not be taxable. The directors accept that, document the reasoning, and price the cover into the business's fixed costs. The point is not the tax break; it is that if Mark dies tomorrow, Dave has £570,000 to clear the finance and keep the company alive long enough to replace what Mark did.

Key Person vs Relevant Life vs Shareholder Protection

Trade business owners frequently mix these three up. They overlap, they are often arranged together, but each answers a different "what if". The table below summarises who is insured, who gets paid, and what the cover is for.

A two-director trade company might sensibly hold all four: key person on the rainmaker, loan protection on the asset finance, relevant life for each director's family, and shareholder protection so the survivor can buy out the other's shares without a dispute with the estate.

Setting It Up Properly

Key person cover is straightforward to arrange but easy to get wrong on the detail. A few practical points:

• Make sure the policy ownership is correct — the business should be the policyholder and beneficiary for key person and loan protection, while relevant life must be written into a suitable trust.
• Match the term to how long the person is realistically a key part of the business, and review it as people approach retirement or change roles.
• Keep each policy purpose distinct. Blending loan protection and profit replacement into one policy muddies the tax analysis.
• Re-check the sum assured at least every couple of years and whenever turnover or borrowing changes.

A Note on Advice

This article is general information for trade business owners, not regulated financial advice or tax advice. The right cover, the right amount and — especially — the tax treatment all depend on your specific circumstances, your shareholdings and the wording of the policy. Set key person cover up with a qualified protection adviser, and confirm the corporation tax and payout position with your accountant before you rely on it. The cost of getting good advice is small next to the cost of discovering, at claim time, that the policy did not do what you assumed.
