If you run a business and you are somewhere in your forties or fifties, the honest answer to how likely you are to die before you reach retirement, or before the exit you are quietly planning, is this: low in any single year, but not low enough to ignore across the ten or twenty years you are counting on. And the thing most likely to kill a working-age business owner in that window is often not the thing you are bracing for.
Most owners picture cancer, or a heart attack at the desk. Those do dominate later. But in the younger half of working age the deaths that actually get registered are led as much by external causes — suicide, accidents and drug-related deaths — as by disease. The picture your imagination paints and the picture the death registers record are not the same, and the gap matters when you are deciding whether the firm, and the people who depend on it, could survive without you.
This page uses the figures the Office for National Statistics publishes for deaths registered in England and Wales, together with its national life tables, to set out what genuinely kills people in their forties and fifties and how the odds shift across the decade before an exit. It cannot tell you your own number — nobody can — but it can tell you where that number lives and how to read it without flinching or fooling yourself.
At a glance
- In any single year at these ages the probability of dying is well under one per cent. Across a full decade it compounds into something you would not want to bet a family or a business on.
- The odds rise with every year of age. Your fifties carry appreciably more risk than your forties, and the curve steepens as you go.
- At younger working ages, external causes — suicide, accidents, drug-related deaths — sit near the top of the list, not far down it, alongside cancer and heart disease.
- Men die at working age far more often than women, and the causes are weighted differently.
- There is no mortality table for company directors. An insurer prices the individual, which is why two owners of the same age can be offered very different terms.
The short answer: small in any one year, not small across ten
Take the reassuring part first, because it is true. For a business owner in their forties, the chance of dying within the next twelve months is small — a fraction of one per cent. Even through the fifties it stays well under one per cent in any single year. If all you ever looked at was this year, you would reasonably conclude there was nothing much to plan for.
The problem is that no one runs a business for a single year. You are planning across a runway — five years to a sale, ten to a management buyout, fifteen to the point where the mortgage is gone and the pension is enough. Every one of those years carries its own small probability, and they stack. A risk that is trivial in January is not trivial when you lay ten Januaries end to end, and it is that cumulative figure, not the annual one, that decides whether the people around you are exposed.
The ONS national life tables are where the underlying yearly probabilities live, published by single year of age and separately for men and women. We have put the cumulative version of this — the plain question of your chance of dying before 65 in real numbers — into a separate piece, and the same compounding logic drives the odds of not finishing a 35-year mortgage. This article is about the other half of the question: not just how many, but from what.

What you assume kills you, and what the register records
Ask most people in mid-life what is most likely to end it, and they will say cancer or heart disease. That instinct is not wrong, exactly — across all ages those two broad groups account for the largest share of deaths in England and Wales. But an average across all ages is dominated by the old, and you are not the average. At your age the ranking is different, and the difference is the whole point of looking properly.
The Office for National Statistics records every registered death by underlying cause and by age band, which means you can see what actually kills people in a given decade of life rather than what kills people in general. When you do that, two things stand out. Disease is still there. But at working age, especially the younger part of it, the causes that people never mention — suicide, accidental poisoning and drug misuse, road and other accidents — climb the list to a height that surprises almost everyone.

External causes: the working-age killers people leave out
This is the part the polished brochures skip. Among men in the younger half of working age, external causes are not a footnote. Suicide is one of the leading causes of death for men under fifty — in some years the single leading cause for the age band — and deaths from drug poisoning and misuse are heavily concentrated in exactly these working years rather than in old age. Accidents, road and otherwise, add more.
None of that fits the mental model of a man who assumes the danger is a tumour he will not spot until it is too late. It should change how you think about protecting a business, because these are not deaths that come with years of warning and a slow wind-down. They are sudden. A firm that would have coped with a founder's managed decline over eighteen months can be flattened by a death that arrives on a Tuesday with no notice at all, leaving no time to appoint anyone, hand over passwords, or reassure a bank.
It is worth being honest about what this means for the mechanics of a company, too. If a sole director dies without warning there may be nobody with authority to sign anything until the family invokes the model articles rule that lets personal representatives appoint a new director, and if there was no will the wait is longer still, because authority over the business hangs on letters of administration being granted. Sudden causes give none of that time.
When cancer and the heart take over
Move up into the fifties and the balance shifts back towards disease. Cancers become the largest single group of registered deaths in this band, with diseases of the circulatory system — heart disease and stroke — close behind. This is the picture people carry around in their heads, and by the fifties it has largely become accurate. The imagined threat and the recorded threat converge.
What does not change is the direction of the overall risk. Each year of age carries a slightly higher one-year probability than the year before, so the late fifties sit meaningfully above the mid-forties on every table the ONS produces. The causes rotate — external causes give ground, cancer and circulatory disease gain it — but the total keeps climbing. That combination, a rising overall risk with a shifting cause mix, is exactly why a fixed view taken once at forty and never revisited tends to be wrong by fifty-five.

Why a man's odds and a woman's odds are so different
If you are working from a single mental figure for "someone my age", you are almost certainly working from the wrong one, because working-age mortality is markedly higher for men than for women and the ONS tables are produced separately for each. The gap is not marginal. It shows up across almost every cause and it is at its starkest in the external causes that dominate younger working age.
Suicide is the clearest example. The great majority of registered suicides are male — consistently around three-quarters of the total — and the male rate has for years run at roughly three times the female rate. Drug-related deaths are similarly weighted towards men. So a couple who own a business together do not share one risk profile: the odds, and the causes behind them, differ enough that any planning done for "the two of us" as a single unit will be wrong for at least one of you.

Reading your own number in the ONS life tables
Here is the honest limit of a page like this. I cannot responsibly print a single ten-year figure for you, because it depends on your exact age, your sex and the nation whose tables apply to you, and a made-up precise number on a page about death and money would be worse than no number at all. What I can do is show you how to read the real one.
The national life tables give, for each single year of age, the probability that a person of that age dies before their next birthday. To think about a decade rather than a year, you are effectively asking the chance of getting through all ten of those birthdays, so the annual probabilities combine across the years rather than simply being averaged. The result is always larger than the comfortable single-year figure you started from, and it grows faster the older the starting age, because you are stacking years that are each individually riskier than the last.
Two cautions when you look. First, use the table for your own sex and nation, not a blended UK average, or you will flatter or frighten yourself for no reason. Second, remember these are population figures. They describe everyone of your age, smoker and non-smoker, well and unwell, high-risk occupation and low. Your own position could sit either side of the line, which is precisely the judgement an insurer is paid to make.
What the odds mean when you are ten years from an exit
Put the two halves together — a small but rising annual risk, and a cause mix that includes sudden, unforeseeable deaths — and the practical question stops being philosophical. It becomes: if the worst arrived inside the window between now and the exit I am planning, does the business have the cash and the authority to carry on without me, or does it fold under the weight of my absence?
That is a solvable problem, and it is worth naming the specific pressure points the odds are really about. There is the tax that can force a sale of the very firm the family wanted to keep, covered in why an asset-rich, cash-poor estate ends up selling the business. There is the borrowing, where a lender has made cover on you a condition of the facility. There is simple continuity of pay and authority in the days after a death. Cover exists precisely because the annual odds are low enough to insure against and the consequences are high enough to matter.
The shape of cover follows the shape of the risk. Where the exposure is a fixed sum over a fixed number of years — the runway to a sale, a defined loan, a buyout obligation — level term cover, which pays a set amount if death falls within the term, is built for exactly that kind of window. What any policy actually pays, and whether it pays at all, depends on its terms and on the underwriting done when it was set up, not on anything a web page promises. If you want that priced against your own age, health and the length of your runway, you can get life insurance quotes through an FCA-authorised broker, and read the wider picture of what a business owner leaves behind in our guide to what dies with a business owner.
Scotland and Northern Ireland
The registration figures quoted above are for England and Wales, because that is the dataset that records cause of death in this detail for this population. The other UK nations keep their own registers: deaths in Scotland are recorded by National Records of Scotland, and in Northern Ireland by the Northern Ireland Statistics and Research Agency. The broad pattern — disease dominating in the fifties, external causes prominent among younger working-age men, a wide gap between the sexes — holds across the UK, but the precise rates differ from nation to nation.
The ONS national life tables are themselves produced separately for each UK nation as well as for the UK as a whole, so if you want the yearly probability that genuinely applies to you, use the table for the country you live in rather than a single UK figure. The direction of the answer will not change. The exact size of it will.
Frequently asked questions
What actually kills people in their forties and fifties in the UK?
The death registrations for England and Wales show cancers and circulatory disease — heart disease and stroke — dominating at these ages, alongside a substantial number of deaths from external causes such as suicide, drug poisoning and accidents. The mix differs sharply between men and women, and it shifts with each decade of age: external causes weigh most heavily in the younger part of working age, while cancer and heart disease increasingly lead as people move through their fifties.
How likely am I to die before I retire?
For someone in their forties the chance across a single decade is small but not negligible, and it rises noticeably with each decade that follows. There is no one figure that fits everyone, because it turns on your exact age, your sex and the nation you live in. The ONS national life tables give the underlying mortality rates by single year of age, separately for each UK nation and for men and women, which is the honest place to read your own odds rather than an average.
Does running a business change my odds?
Occupation and lifestyle affect mortality, but there is no national mortality table for company directors specifically, so nobody can quote you a "business owner" figure. When you apply for cover an insurer assesses age, smoking status, health history, family history and occupational risk, which is why two owners of the same age can be offered very different terms. The population life tables are the starting point; your own circumstances move you off them in one direction or the other.
