If you run a one-person limited company, life insurance is not one decision. It is three, because you are three different clients wearing the same coat. You are the employee the company pays, the owner whose shares hold the value, and, through the company, your own employer. Each of those roles faces a different loss when you die, and each is answered by a different kind of cover. One generic policy bought off a comparison site answers, at best, one of them.

The most useful thing to understand about life insurance for a single director limited company is that it is not really a product at all. It is a question about which of your three hats you are trying to protect. Get that straight first and the rest follows. Confuse the hats — which is what happens when you simply buy the cheapest policy that appears — and you can end up with cover that lands in the wrong place, is taxed the wrong way, or is aimed at a loss you were not actually worried about.

Here is the map, before the detail.

At a glance

  • As an employee, your company can pay for a relevant life plan that pays your family through a trust.
  • As an owner, your shares carry value your family may not be able to spend, run or easily sell.
  • As the business, key person cover pays the company itself for the profit and borrowing your death exposes.
  • These are three separate pots of money doing three separate jobs. Do not expect one policy to do all three.
  • Company-paid cover is not automatically cheaper or better. It is money taxed differently, reaching different people.

The short answer: you are three clients at once

A one-person company is a legal fiction that works entirely in your favour until the moment you die, at which point it starts working against your family unless you have planned for it. The company is a separate legal person. It employs you, it owns the trade, and it is owned by you through your shares. Those three relationships are usually invisible because one human being — you — stands in all of them at the same time.

Death separates them instantly. Your employment ends. Your shares pass to your estate. And the company, which is not you, carries on existing with nobody to run it. Because each of those events lands on a different person — your family, your estate, the business — no single insurance payment can catch all three. That is not a sales point. It is just the shape of the problem, and it is why "what life insurance should a contractor or single director have" never has a one-line answer that is honest.

Take the three roles in turn.

Hat one: the employee — a relevant life plan

As far as your company is concerned, you are staff. You have a contract of employment, you are paid a salary, and the company can provide you with the benefits an employer provides. A relevant life plan is one of those benefits: a death-in-service policy for a single life, arranged and paid for by the company, written in a discretionary trust so the payout goes to your family rather than into the business.

This is the piece a sole trader cannot have, because a sole trader is not employed by anyone — but a director of a limited company is genuinely an employee of that company, so the route is open to you. The plan pays a lump sum if you die (and usually if you are diagnosed as terminally ill) while you are still employed. Because it is arranged as an employee benefit and held in trust, the money is designed to reach your family without waiting for probate, and a qualifying plan is not normally treated as a benefit in kind on your P11D.

Two honest cautions. First, the corporation tax deduction that broker pages promise is not automatic — the premium has to satisfy HMRC's wholly and exclusively test as part of your remuneration, and that is a judgement rather than a certainty. Second, the cover is tied to the job. It runs while you are an employee of that company and stops when you stop, which catches people out at retirement: relevant life cover ends the day the directorship does, so it is not a policy to rely on into your seventies. If you want the full picture of the company footing the bill, we set it out in whether your limited company can pay for your life cover.

Hat two: the owner — your shares, your family and the tax

Your shares are the second hat, and they are the one people forget because they feel like an abstraction. They are not. Your shares are an asset with a value, and on death that value passes to whoever inherits it — usually your spouse or your children. The trouble is that the value sits inside a trading company. It is not cash. Your family may inherit shares worth a great deal on paper while being unable to draw a penny from them, run the business that generates them, or find anybody to buy them.

There is a tax edge to this as well. Shares in a genuine trading company have long attracted business relief for inheritance tax, but from April 2026 that relief is capped, so an ordinary trading company above the allowance can leave a real, payable tax bill — we work the numbers in why business relief now only halves the tax above the allowance. For a family with no cash and a company they cannot easily sell, that bill is the thing that forces a rushed sale.

Cover for this hat is personal or estate cover: a policy, often written in trust, sized against what your family actually needs — to replace your income, to meet any tax that falls due on the shares, and to give them room to decide what to do with the business rather than being forced. If your affairs are not tidy in this respect, this is also where an unmarried partner is most exposed, because they do not inherit automatically: if that is you, read what happens when your partner runs a limited company and you are not married before you assume the shares simply pass across.

Hat three: the business itself — key person cover

The third hat is the company as a thing in its own right. In a one-person business the company and you are, commercially, the same entity: the profits come from your work, the client relationships are yours, and the bank lent to the company on the strength of you. When you die, the company loses all of that at once, and it still has obligations — an overdraft, a lease, invoices, perhaps a loan the bank secured on your home.

Key person cover answers this hat. The company owns the policy, pays for it, and receives the payout, using it to steady the business: to repay borrowing, to buy time, or to fund an orderly wind-down if that is the only realistic outcome. This is different money from the relevant life plan — it belongs to the company, not the family — and it can be taxed differently, so how it is set up matters and is worth checking rather than assuming.

This hat matters most where the company's borrowing reaches beyond the company. Many small-company facilities are only granted against a personal guarantee, and that guarantee can reach the family home: your house may be standing as security for the company overdraft without your family realising it. Cover that clears the borrowing protects the home as much as the business.

Why one generic policy answers none of the three

Set the three hats side by side and the problem with the single off-the-shelf policy becomes obvious. Buy personal cover only, and the business is exposed and the tax on the shares is unfunded. Buy key person cover only, and your family gets nothing directly. Take a relevant life plan and stop there, and the shares and the borrowing are still unaddressed. Each policy is correct for its own hat and silent on the other two.

It is also why the amount matters as much as the existence. A single figure plucked from a comparison site is not sized against any of the three real numbers: your family's income need, the value and tax on the shares, or the company's borrowing. Those are three different sums, and they change at different times — the borrowing falls as you repay it, the share value rises as the company grows, the family's need shifts as children grow up. A plan that made sense at incorporation can be wrong on all three counts five years later.

None of this means you need three expensive policies on day one. It means you should know which hat each pound of cover is protecting, so that gaps are a choice rather than an accident. When a company owner dies with only one of the three covered, the first fortnight is where the gaps show — we describe it in the first two weeks after a company owner dies.

"Should the company pay?" — different money, not cheaper money

The question people actually type is whether the company should pay for their life insurance, usually because they have heard it is cheaper. That framing is the trap. Company-paid cover is not a discount on personal cover; it is a different arrangement, doing a different job, taxed under different rules and reaching different hands.

A relevant life plan is the company buying an employee benefit for you, paid before the money reaches you as income, and paying your family through a trust. Personal cover is you buying protection out of income the company has already paid you and you have already been taxed on. Key person cover is the company protecting itself and keeping the proceeds. Deciding between them on price alone misses the point, because they do not pay the same people. The right question is not "which is cheapest" but "which loss am I funding, and who needs the money to land with?"

If the honest answer is that all three losses worry you, then the sensible next step is to have the three sums priced separately against your real figures rather than guessing. You can get life insurance quotes and ask an FCA-authorised broker to structure the relevant life, the personal and the key person elements as what they are, instead of collapsing them into one policy that fits none of them.

What to check before you buy anything

Before you arrange or renew cover, it is worth pinning down a few things that decide which hat is most exposed:

  • What has the company borrowed, and on what security? An overdraft, asset finance or a loan backed by a personal guarantee changes the size of the business and home problem.
  • Who inherits the shares, and can they use them? A spouse who cannot run the trade, or an unmarried partner who does not inherit automatically, changes the owner problem.
  • Is any existing policy in trust, and who benefits? A policy paid to your estate rather than through a trust can be slower to reach your family and may add to the estate for tax.
  • Does the cover term match how long you will need it? Cover tied to the company ends with the job; personal cover does not.

None of this requires you to decide everything at once. It requires you to know which of the three hats is currently bare, so that if you cover only one this year, you cover the one that would hurt most.

Scotland and Northern Ireland

The three roles, and the cover that answers each, work the same way across the United Kingdom. Company law is the same wherever the company is registered, and relevant life plans, key person cover and the tax treatment of premiums are governed by HMRC rules that apply UK-wide.

What differs is the machinery that deals with your estate and your shares after death. In Scotland the personal representatives obtain confirmation rather than a grant of probate, and the terminology and timescales differ; in Northern Ireland probate is handled through its own office. Writing a policy in trust matters partly because it can sidestep some of that delay, letting the money reach your family while the estate itself is still being sorted out. The principle — three hats, three answers — does not change; only the paperwork around the shares does.

Frequently asked questions

What life insurance can a single director limited company have?

Three arrangements answer three different needs. A relevant life plan is a death-in-service benefit the company pays for on you as its employee, paid to your family through a trust. Key person cover is owned by the company and protects the business against the losses your death causes it. Personal or shareholder cover deals with what your family and your shares actually require. Most single-director companies need more than one of these, because each leaves the others unaddressed.

Is company-paid life cover better than personal cover?

It is not automatically better; it is different money doing a different job. Company-paid cover under a relevant life plan is an employee benefit, paid before the money reaches you as income and delivered to your family through a trust. Personal cover is bought from income you have already been taxed on, and you own it outright. Which is right depends on who you need the money to reach and which loss you are funding, not on price alone.

Can my company just pay for my normal life insurance?

If the company pays the premiums on a policy you own personally, that is usually treated as your earnings or a taxable benefit, and the corporation tax position is not straightforward either. The relevant life route exists precisely because it is structured to avoid that treatment: the plan is set up as an employee benefit in trust rather than as the company quietly paying your personal bills. Take advice on the structure before assuming the company can simply foot the premium.
