Most directors don’t set out to ignore risk. It just tends to build in the background.
The business grows. Revenue becomes more concentrated. One or two people become central to how things run. At the same time, personal protection often sits off to the side, paid privately and rarely reviewed.
That is usually when the conversation around relevant life vs key person insurance starts to surface. Not because the products are similar, but because the risks they cover begin to overlap in real life.
They solve different problems. But those problems often sit inside the same business.
What relevant life insurance actually does in practice
Relevant life insurance is a way for a limited company to provide life cover for a director or employee. The company pays the premiums. The benefit is paid to the individual’s beneficiaries.
The structure is what makes it useful.
In most cases, premiums are treated as an allowable business expense, so they are paid before corporation tax. There is no benefit in kind for the individual, which means no additional personal tax charge. The policy is written in trust, so the payout usually sits outside the estate and is not subject to inheritance tax. It is typically paid as a tax-free lump sum to the family.
This is where many directors pause. Not because they did not want life cover, but because they had been funding it in a less efficient way.
A common behaviour is this: directors take dividends, pay personal tax, and then use what remains to fund a life policy. It works, but it is rarely the most efficient route.
Relevant life shifts that cost back into the company.
A practical example directors recognise
A director earning through a mix of salary and dividends is paying for a £500,000 personal life policy from their net income. The monthly cost is manageable, but it comes from money that has already been taxed.
The company replaces that with a relevant life policy. The premium is paid directly by the business, reducing taxable profit. There is no benefit in kind. The cover amount stays broadly similar, but the funding structure is cleaner.
If the director dies while employed, the payout goes into trust and is paid to the family. Not through the business. Not through the estate.
It is a small structural change with a noticeable financial impact over time.
For technical detail, HMRC outlines the treatment of these policies under employment income rules (GOV.UK).
Where key person insurance fits instead
Key person insurance sits firmly on the business side.
It exists to protect the company against the financial consequences of losing someone critical. That could be a director, a senior salesperson, or a specialist employee whose knowledge is difficult to replace.
This is not about family protection. It is about continuity.
The policy pays a lump sum to the business if that person dies or is diagnosed with a critical illness, depending on the cover. That money can be used however the business needs. Replacing lost revenue, funding recruitment, covering debt, or simply buying time.
There is no standard use case. It depends on how the business actually operates.
What this looks like in real businesses
In many SMEs, revenue is not evenly distributed. One director might bring in 60% of new business. Another might hold key supplier relationships or technical oversight.
When advisers review businesses, they often see the same pattern. The business is profitable, but fragile in specific areas.
If that person is removed suddenly, the issue is not just emotional. It is immediate financial pressure.
Key person insurance is designed to absorb that shock.The Association of British Insurers highlights that business protection policies are commonly used to support continuity planning in SMEs (ABI).
How directors tend to approach this in reality
Very few directors start with both.
Most begin with a personal life policy, paid privately. Over time, as the business becomes more established, they look for a more efficient structure. That is where relevant life often comes in.
Key person insurance usually appears later. Often after a trigger point. A health scare. A difficult year. Or seeing another business struggle after losing someone important.
By that stage, the risk has already been there for some time.
The gap is not a lack of awareness. It is timing.
Where the real decision sits
Relevant life insurance deals with personal financial responsibility. It answers the question of how a director’s family would cope financially.
Key person insurance deals with commercial resilience. It answers how the business would cope operationally and financially.
They sit on different sides of the same coin.
A business can survive without one. It is harder to argue it is properly protected without either.
A final perspective grounded in how businesses actually run
Most SMEs are more dependent on individuals than they first appear. That dependency does not always show up in the accounts. It shows up in conversations, relationships, and decision-making.
Relevant life insurance recognises that directors still have personal responsibilities outside the business, and structures that protection in a tax-efficient way.
Key person insurance recognises that the business itself can be vulnerable to the loss of those same individuals.
Neither is complicated in isolation. The difficulty is usually recognising when both are needed.
For many directors, the starting point is not choosing between them. It is stepping back and looking at where the real pressure would land if something unexpected happened.
