Keyman Insurance for Sole Traders, Partnerships & Ltd Companies — Which Applies?

Keyman insurance is designed for limited companies. Sole traders and ordinary partnerships need a slightly different toolkit to achieve the same outcome — protecting the business against loss of an essential person. This guide walks through what each UK business structure can and can’t buy, and what alternatives close the gap.

Quick facts

• Keyman policies require a corporate body as policyholder — sole traders cannot directly buy them.
• Limited companies are the cleanest fit for the standard product.
• Partnerships and LLPs use parallel structures (partnership protection) with the same insurers.
• Sole traders use personal life cover, often written in trust, with business-loss provisions.

Limited companies — the textbook case

The limited company is both the proposer and the policyholder. The named director or employee is the life assured. Premiums are paid by the company; the lump sum lands in the company bank account.

Tax: typically deductible under HMRC Anderson tests; payout taxable as trading income. See Keyman insurance and corporation tax.

This is the standard pattern covered throughout our keyman insurance product page and the key person protection for limited companies guide.

Ordinary partnerships and LLPs — partnership protection

Partnerships do not have a corporate body that can hold a keyman policy. Instead, partnership protection works through:

1. Each partner takes out a life policy on their own life, written in trust for the surviving partners.
2. A cross-option agreement gives the survivors the option to buy out the deceased partner’s share, and the estate the option to sell.
3. The trust pays the lump sum to the surviving partners, who use it to fund the buy-out.

This is structurally a hybrid of keyman and shareholder protection. Same insurers, same underwriting, different contract structure.

Sole traders — what is actually available

A sole trader is legally indistinguishable from their business. There is no corporate body that can be a policyholder, so there is no UK keyman product available to a true sole trader. The right toolkit:

• Personal life insurance — written on the sole trader’s own life. Often placed in trust to keep proceeds outside their estate.
• Income protection — replaces a percentage of trading income if illness or injury stops the sole trader from working.
• Critical illness cover — lump sum on diagnosis of listed serious conditions.
• Mortgage / loan protection — specifically clears business debts on death.
• Public liability insurance — not life cover, but the indispensable everyday protection — see public liability for sole traders.

If you are a sole trader thinking about incorporating

One of the protection-side benefits of incorporating to a limited company is gaining access to corporate-owned keyman insurance with potentially deductible premiums. If you are already at the size where you have employees or material trading risk, it is often worth speaking to your accountant about the broader case for incorporation.

Frequently asked questions

Can a sole trader take out keyman insurance?

Not in the strict UK sense — keyman insurance requires a corporate policyholder. Sole traders use personal life insurance, often in trust, with a business-loss provision.

Can a partnership buy keyman insurance?

Not directly — partnerships use partnership protection: each partner insures their own life in trust for the survivors, paired with a cross-option agreement.

Is keyman insurance only for limited companies?

The strict-sense product is, yes. The functional equivalent (life cover that protects the business and family from death of the principal) is available to every UK business structure under different product names.

Should a sole trader incorporate to access keyman cover?

Not for that reason alone — but incorporation does open access to corporate-owned protection products with potentially favourable tax treatment. Discuss the wider commercial case with your accountant.

Where can a partnership get partnership-protection cover?

From the same UK whole-of-market insurers (Aviva, L&G, LV=, Royal London, Vitality, Zurich, Scottish Widows). Quote via the keyman insurance quote form — the broker will route to the appropriate product.
