Keyman Insurance UK Cost in 2026 — How Much Should You Pay?

Keyman insurance in the UK is normally cheaper than business owners expect. For a healthy non-smoker in their 30s, £250,000 of life-only keyman cover starts at around £10–£18 per month on a 5-year term. Critical illness roughly doubles that. Below are the live 2026 ranges, the variables that move the price, and a simple way to estimate your own quote.

Quick facts: what affects the cost of keyman insurance?

• Age — premiums roughly double every decade after 35.
• Smoker status — smokers pay 1.5–2.5× non-smoker rates.
• Sum assured — pricing is broadly linear (£500k costs ~2× £250k).
• Cover type — adding critical illness adds 80–120%.
• Term length — a 10-year term costs more per year than a 5-year term, but locks the price in.
• Health and lifestyle — BMI, blood pressure, cholesterol, family history.
• Occupation — high-risk jobs (offshore, construction at height) load the premium.

How much does keyman insurance cost on average in the UK in 2026?

Indicative monthly premiums — 5-year level term, life only, non-smoker, standard occupation:

Ranges reflect the spread across major UK insurers (Aviva, Legal & General, LV=, Royal London, Vitality, Zurich) for standard underwriting in May 2026 and are illustrative.

How much extra does critical illness add?

Adding accelerated critical illness cover to the same policy roughly doubles the premium:

Worked example: a 38-year-old founder, £750,000 of cover

1. Founder’s gross profit contribution to the business: ~£300,000/year
2. Cover requested: 2.5× profit contribution = £750,000
3. Policy: 7-year level term, life-only, non-smoker, standard underwriting
4. Likely premium range: £32–£55/month
5. Annual cost to the business: ~£384–£660
6. For context, that is well under 0.25% of what the policy pays out at claim.

What price might be too good to be true?

If you are quoted a price that looks dramatically below the table above, check four things:

• Is it guaranteed or reviewable (reviewable premiums can rise sharply at year 5/10)?
• Is the term shorter than you actually need (1 year vs the 5–10 you intend)?
• Is critical illness included or stripped out?
• Are loadings hiding behind “subject to underwriting”?

Is keyman insurance tax-deductible?

If the policy passes HMRC’s Anderson principles — cover on an employee (not a major shareholder), term-only, sum assured wholly to compensate trading loss — premiums can be a deductible business expense and the payout is taxable as trading income. We unpack the tests, with examples, in Keyman insurance and corporation tax.

How to bring the cost of keyman insurance down

• Buy younger. A 5-year guaranteed-rate policy taken at 35 vs 45 typically costs ~40% less, and locks the price in.
• Quit smoking 12 months before applying. Most insurers re-rate you as a non-smoker after a clean year.
• Right-size the cover. Use the calculator on our main keyman insurance page rather than buying round numbers.
• Strip CI out if your business risk is genuinely only “death of key person” — CI is the most expensive component.
• Use level (not increasing) cover if your debt or risk is fixed.
• Shop the whole UK market. Premium spreads of 30–40% between insurers are common at higher sums assured.

Frequently asked questions about keyman insurance cost

Is keyman insurance expensive?

For most healthy directors under 50, no — cover under £500,000 typically costs less per month than a single line on the company’s mobile bill. Cost rises sharply with age and adding critical illness.

How is the premium calculated?

Insurers price by mortality risk × sum assured, modified by occupation, lifestyle and term length. The biggest moving parts are age, smoker status, sum assured and whether critical illness is bolted on.

Can I pay annually instead of monthly?

Yes — most insurers offer a small discount (typically 2–5%) for annual payment.

Will the premium change during the policy?

If you choose guaranteed premiums, no — locked for the term. Reviewable premiums can be re-rated by the insurer at set review points (often year 5 or 10).

Are keyman insurance premiums tax-deductible?

Often, yes — if the policy meets HMRC’s Anderson tests. See Keyman insurance and corporation tax for the detail.

What is the cheapest way to insure a key person in the UK?

Life-only cover on a level term, paid annually, applied for in your 30s with non-smoker status and standard underwriting. Critical illness is the single biggest add-on cost — consider whether you really need it.
