Why UK limited companies should review their key person insurance in 2026
Every UK limited company relies on people who keep the business running. Directors, senior managers, technical leads, and revenue-driving staff often hold responsibilities that cannot be passed on overnight. When one of these individuals is suddenly unavailable, the financial impact can be immediate.
As 2026 approaches, many companies are discovering that protection arranged years ago no longer reflects how their business operates today. A structured review of existing arrangements, supported by a UK key person insurance specialist, can help directors identify gaps that may otherwise go unnoticed.
Many businesses set up key person cover during early growth stages and rarely revisit it. Since then, turnover may have increased, borrowing may have changed, and individual roles may now carry far greater responsibility. Without review, the business risks relying on outdated assumptions.
What key person insurance actually covers
Key person insurance is a policy owned by the company. It pays a lump sum to the business if a named individual dies or suffers a serious medical condition covered by the policy. The insured person is usually someone whose absence would disrupt trading, affect contracts, or reduce income.
The payout can support the business by:
- Covering lost income during disruption
- Paying for recruitment or training
- Meeting loan repayments
- Supporting overheads while operations stabilise
In the UK, this form of protection is commonly arranged through life insurance or combined life and serious illness cover, depending on the risk profile of the role involved.
Why 2026 is a turning point for UK companies
Several current conditions make 2026 a sensible time for review rather than delay.
First, sickness and absence remain a major issue for employers. Official labour market data shows that around 148.9 million working days were lost due to sickness or injury in the UK, with an average of 4.4 days lost per worker. If a company has a £2 million turnover and one director is responsible for 40% of revenue, the potential financial exposure could be £800,000 before recruitment and disruption costs are considered.
Second, the financial cost of absence is substantial, particularly for smaller firms. Research shared by Unum Limited, based on a YouGov survey of over 2,000 UK decision-makers, shows that the median cost of employee sickness for UK SMEs is about £27,964 per year, equivalent to around 1.7% of average total turnover, highlighting a significant drag on business performance for many smaller organisations.
Third, Gov.uk analysis highlights that employers lose an average of £120 per employee per day due to sickness absence, placing sustained pressure on cash flow when disruption occurs.
Together, these figures underline why people-related risk deserves attention alongside financial and operational planning.
Common reasons policies fall out of step
A large number of UK limited companies already hold some form of key man insurance. The issue is not absence, but relevance.
Typical causes of mismatch include:
1. Outdated cover amounts
A policy arranged when turnover was £500,000 may be far too low for a business now generating several million pounds in annual revenue.
2. Role expansion
A director who once handled sales alone may now manage finance, supplier contracts, and compliance matters. The risk attached to that role increases accordingly.
3. Change in ownership or shareholding
When equity shifts, the financial effect of losing a shareholder-director can differ from the original assumptions.
4. New borrowing
Loans taken after the policy started may not be reflected in the insured sum, leaving lenders exposed.
5. Tax treatment assumptions
HMRC guidance has evolved, and older policies may not follow current practice regarding premium deductibility or payout treatment.
The real cost of losing a senior individual
Directors often focus on salary cost when thinking about people risk. In practice, the effect is wider.
Recruitment fees, onboarding time, lost contracts, and delayed decisions can all affect revenue. Industry analysis suggests that many small businesses struggle to remain operational for more than 12 months after losing a senior decision-maker, particularly where no financial buffer exists.
For companies with lean management structures, the absence of one person can also affect staff confidence and supplier relationships, adding further strain.
Lending, investors, and continuity planning
Key person cover is often linked to lending decisions. Some loan agreements include specific requirements for business protection insurance. Others expect it to exist as part of risk management, even if not written into the contract.
Investors also assess dependency risk. A business that relies on one or two individuals without financial protection may be seen as fragile. A review shows that directors have considered continuity planning rather than reacting after a problem arises.
Tax treatment and why structure matters
UK tax treatment is one of the most misunderstood aspects of this type of cover. HMRC treatment depends on the policy meeting qualifying conditions and being structured correctly from the outset.
HMRC generally applies a “sole purpose” test. If a policy exists to protect trading profits, premiums may be allowable as a business expense, but the payout may then be taxable. Where the intention is capital protection for the director’s family, premiums may not be deductible, while proceeds can fall outside corporation tax.
In practice, the correct position depends on the policy wording, ownership structure, and the intended use of the payout. A review allows companies to confirm that the policy still aligns with its intended tax outcome as circumstances change.
Life cover versus serious illness protection
Many businesses focus on life cover alone. However, data from UK health organisations shows that serious illness during working age is statistically more likely than death. Long-term absence due to illness can disrupt a business in the same way.
Including serious illness cover as part of key person insurance can provide support during extended absence, allowing the company time to reorganise without immediate financial strain.
Regulatory dependency and operational risk
Some sectors depend on named individuals for regulatory approval or technical sign-off. Financial services firms, engineering companies, healthcare suppliers, and data-driven businesses often fall into this category.
If one person holds essential certification or authority, operations may slow or stop entirely if they are unavailable. While insurance cannot replace approval, it can support the business financially while solutions are arranged.
When professional input adds value
Internal reviews often focus on benefit amounts alone. In reality, structure, ownership wording, and tax alignment matter just as much.
Involving a UK key person insurance specialist during review helps directors assess exposure more accurately, particularly where:
- Multiple directors are insured
- Borrowing is involved
- Ownership has changed
- Expansion or sale is planned
This supports informed decisions rather than rushed changes later.
What a proper review usually covers
A review does not automatically mean replacing the cover. In many cases, small adjustments are enough.
A structured review typically looks at:
- Current turnover and valuation
- Dependency on named individuals
- Outstanding finance
- Existing policy terms
- Tax position under current HMRC practice
The aim is alignment, not complexity.
The risk of waiting too long
Insurance only works if it reflects the risk at the time of loss. Waiting until a disruption occurs leaves directors with limited options.
UK insolvency data consistently shows that cash flow interruption remains a leading cause of business failure following unexpected events. Reviewing key person insurance before problems arise helps reduce uncertainty during difficult periods.
Planning rather than reacting
For UK limited companies, people-related risk remains one of the hardest to manage. In 2026, rising costs, cautious lenders, and concentrated responsibility make review a sensible step. Checking existing arrangements helps confirm that protection reflects current operations rather than historic assumptions.
Frequently asked questions
How often should key person insurance be reviewed?
A review is sensible every two to three years, or sooner if turnover, borrowing, or senior responsibilities change.
Can a company insure more than one key person?
Yes. UK limited companies often insure several directors or senior employees under separate policies.
Does key person insurance only cover death?
No. Policies may cover death only or include serious illness, depending on how the cover is arranged.
Who receives the payout from a key person policy?
The company receives the payout, not the individual or their family.
Is key person insurance tax deductible in the UK?
It depends on the policy purpose and structure. HMRC assesses this on a case-by-case basis.
Is key person insurance a legal requirement?
No, but lenders and investors may expect it where a business relies heavily on named individuals.
