Life insurance does pay out for natural causes, including illness, heart failure and old age, provided the death happens while the policy is in force and its conditions, such as an accurate application, are met. The words "natural causes" matter most on over-50s plans, where several providers hand back the premiums paid, not the cover amount, if death from illness comes in the plan's first year or two.

Policy wording differs, and the insurer's documents are the starting point; an FCA-authorised broker can also explain them, and sending your number through this page's form arranges that call at no cost.

Heart failure, a stroke or cancer: does the illness change a claim?

No. Aviva's Life Insurance Plan conditions (DA03011 05/2023) pay the death benefit "if the life covered dies during the policy term", and Legal & General's Life Insurance terms (QGI12849 - 2026/10) cover a death or terminal illness diagnosis between the start date and the expiry date. Neither of those sentences names a cause, so a death from heart failure, a stroke or cancer inside the term is a claim like any other. The exclusions that can still apply are set out in what life insurance pays out for.

What a claims team checks instead is timing and the application: whether the death fell inside the term, whether premiums were kept up, and whether the health questions were answered accurately, which the section on refused claims covers.

Old age is the awkward case, because it comes after a term policy has run out. Aviva's policy summary (DA03008 05/2023) lists a death outside the policy term among the cases where it does not pay. How the end date works is set out in how long term life insurance lasts.

Why do over-50s plans treat a natural death differently at first?

Not always. Plans sold to older buyers without health questions often pay differently at the start, and the rule differs by provider:

PlanWhat its terms say about a natural-cause death at the start
Aviva Over 50s Life Insurance (policy conditions DA03016 07/2023)Before the first anniversary, a death from natural causes brings back an amount equal to the premiums paid; an accidental death is paid at the full cover amount. From the first anniversary the cover amount is paid.
SunLife Guaranteed Over 50 Plan (S-G050T12.25.V3)For a death in the first year other than from an accident, all premiums paid are returned; an accidental death within 90 days of the accident is paid the cash sum. After the first year the fixed cash sum is paid.
Shepherds Friendly Over 50s Life Insurance (O50.2026.03.TC)Within the first two years, a death from natural causes or a medical condition returns 150% of the premiums paid instead of the lump sum, provided payments are up to date; an accident is the exception.

These are three providers' wording, not a market rule, and the period in your own paperwork is the one that counts. A death that follows a long illness is still a natural cause, so the date the plan started matters more than the diagnosis date. The same idea on funeral insurance is covered in funeral cover waiting periods, and Aviva's plan in more detail in Aviva life insurance over 50.

If a plan's opening period is hard to follow from its documents, the broker who phones you back can walk you through it free.

Does whole of life cover pay out when you die of old age?

That is what it is built for. Aviva's over-50 page explains that whole of life cover "lasts for as long as you live rather than a set period of time", and pays out a lump sum when you die. So the payout does not stop at a set age in the way a term policy ends.

The premiums can stop earlier than the cover does. SunLife's plan terms say premiums cease on the policy anniversary on or after your 95th birthday, or on your death if that happens before then. Whether the sum paid is more or less than the premiums you have paid depends on how long you live, which is why plans like these are worth comparing. See what whole of life insurance is for how the two types differ.

Can a claim for an illness death still be turned down?

It can if the application was not answered accurately. The Consumer Insurance (Disclosure and Representations) Act 2012 says the consumer has a duty "to take reasonable care not to make a misrepresentation to the insurer." Legal & General's terms set out what follows. Where inaccurate information is given deliberately or recklessly, it is entitled to cancel the policy and withhold the cover amount, and may keep the premiums already paid; where they were given through carelessness, it can instead change the policy to the terms it would have offered had it known the facts.

If you complain, the Financial Ombudsman Service weighs up how clear the questions were, whether you answered with reasonable care and whether honest answers would have led the insurer to act differently. Life insurance disclosure requirements explains what counts as a misrepresentation, and can a life insurance company refuse to pay covers the other grounds an insurer can rely on.

What if the illness is terminal?

Both term policies quoted here can pay before death. Legal & General defines terminal illness as an illness with no known cure, or one that has progressed so it cannot be cured, where the hospital consultant and its Medical Officer expect death within 12 months. Aviva's policy summary lists a terminal illness diagnosis with an expected survival of more than 12 months among the cases it does not pay. Once such a claim is paid the cover ends. Claim conditions are explained in terminal illness benefit in life insurance.

Two causes of death get their own pages: life insurance and dementia and drug-related deaths. An illness that is survived is a critical illness matter, covered in whether critical illness cover pays on death.

Frequently asked questions

Is heart failure a cause of death a policy will pay for?

Yes, if the policy was in force and the application was accurate. Heart failure is an illness, and the wording quoted above looks at when the person died rather than the cause.

Is a fatal heart attack paid differently from one the person survives?

A fatal heart attack within the term is a death claim. A heart attack the person survives is not a death, and only critical illness cover that names it can pay for that: critical illness cover and heart attacks explains how.

Does an illness count as natural causes on an over-50s plan?

On these plans the line is drawn between an accident and everything else. Shepherds Friendly's terms put "natural causes or a medical condition" together, and SunLife returns premiums for a first-year death other than from an accident; each plan defines an accident in its own terms.

Who can tell me what my own policy covers?

The insurer's own documents are the starting point for what your policy covers, and a broker can help with the wording too; no fee applies to the call, which you request by filling in this page's form.
