Living longer changes financial planning — but what does it mean for life insurance?
Longer lives continue to reshape retirement, pension and insurance planning in the UK — but life expectancy is not increasing evenly for everybody.
The latest Office for National Statistics national life tables show UK life expectancy at birth at 83.0 years for females and 79.1 years for males in 2022 to 2024.
At age 65, average remaining life expectancy was a further 21.2 years for females and 18.7 years for males.
Those figures create two very different financial planning questions.
The first is:
How do you make money last if you live for a long time?
That is primarily a question for pensions, savings, investments and later-life planning.
The second is:
What happens financially to the people who depend on you if you die earlier than expected?
That is where life insurance can play a role.
Understanding the difference matters because life insurance is designed to protect against premature death, not to fund a long retirement.
Living longer does not mean life insurance needs to last forever
Most ordinary life insurance in the UK is term insurance.
The policy runs for a defined period — perhaps 20, 25 or 30 years.
If the insured person dies during that period and the claim meets the policy terms, the policy pays out.
If they survive beyond the end of the term, the cover normally finishes without a payout.
That is not a failure of the policy.
It means the insured financial risk did not happen during the period it was being protected.
Our guide to how long a life insurance policy should last explains why the appropriate term should normally be linked to the financial responsibility rather than simply somebody's expected lifespan.
For many households, there is no need for ordinary family protection to continue until death.
The aim is to provide cover during the years when somebody else would be financially vulnerable if you were no longer there.
Match the policy term to the dependency
The most useful way to choose a life insurance term is to identify what you are protecting and when that need is expected to end.
For example:
Children
Parents may want cover to remain in place until their youngest child is expected to become financially independent.
If the youngest child is three, a 20- or 25-year need may be reasonable depending on the family's plans.
Mortgage
If the main purpose is mortgage protection, the policy term will often be linked to the remaining mortgage term.
Our guide to how life insurance works with a mortgage explains why allowing life cover to expire several years before the mortgage ends can create an obvious protection gap.
Partner dependency
A household may want cover until a surviving partner reaches retirement, builds sufficient pension provision or becomes less dependent on the insured person's income.
Business protection
Business owners can have quite different needs, particularly where a death could leave debts, ownership problems or a loss of key income.
Estate planning
Where the financial need is expected to exist whenever death occurs — for example, providing liquidity for a potential inheritance-tax liability — permanent cover such as whole-of-life insurance may be considered rather than temporary term assurance.
The correct term therefore depends on the liability.
There is little value in automatically choosing the longest policy available if the financial dependency will disappear decades earlier.
A longer term usually costs more
Policy length affects price because an insurer is taking on risk for a longer period.
Consider someone aged 35.
A 15-year policy protects them only until age 50.
A 35-year policy protects them until age 70.
All else being equal, the second arrangement exposes the insurer to a much greater chance of having to pay a claim.
That will normally be reflected in the premium.
Choosing an unnecessarily long term can therefore mean paying for protection during years when nobody may still depend on it.
But choosing too short a term creates the opposite problem.
If a policy ends while there is still:
- a mortgage;
- a financially dependent partner;
- children at home;
- education costs;
- shared debts; or
- reliance on the insured person's income,
new cover may be needed later.
And arranging that replacement cover may be more expensive.
Living longer does not eliminate the risk of dying early
Population life expectancy can sometimes give a misleading impression of personal risk.
An average lifespan of around 79 or 83 years does not mean every individual will live to approximately that age.
Some people live much longer.
Others die substantially earlier.
That uncertainty is precisely why protection insurance exists.
The financial question is therefore not:
“How long am I expected to live?”
It is:
“What would happen to the people who depend on me if I did not live that long?”
Our guide to whether you really need life insurance starts with that dependency rather than assuming everybody automatically needs cover.
Someone with no dependants, no shared debt and substantial assets may have little need for family protection.
Someone of the same age with young children and a large mortgage may have a significant need.
Life expectancy is not the same for everyone
National averages also hide substantial differences.
The latest ONS figures show life expectancy varies between the UK nations.
In 2022 to 2024, life expectancy at birth was:
- 83.3 years for females and 79.4 for males in England
- 82.6 and 78.8 in Northern Ireland
- 82.2 and 78.3 in Wales
- 81.1 and 77.1 in Scotland
There are also significant differences within countries and between local areas.
Health, deprivation, occupation and wider social and economic circumstances all contribute to different mortality patterns.
That is why a national life-expectancy statistic should not be interpreted as a personal forecast.
It tells us something important about populations.
It does not tell an individual when they will die.
Insurers assess individuals rather than simply applying the national average
Life insurers use large amounts of mortality data when constructing and pricing products, but an individual application is also assessed using personal information.
Depending on the insurer and cover requested, underwriting can consider factors including:
- age;
- medical history;
- current health;
- smoking or vaping;
- height and weight;
- occupation;
- alcohol consumption;
- family medical history;
- lifestyle;
- hazardous activities; and
- amount and length of cover.
This is why two people of the same age can receive different premiums.
Our guide to life insurance with a pre-existing medical condition explains how medical history can affect underwriting without necessarily preventing somebody from obtaining cover.
Population longevity provides the background.
Personal underwriting determines the individual insurance decision.
Age matters when arranging new cover
Longer life expectancy does not mean life insurance automatically becomes cheaper as someone gets older.
Quite the opposite is usually true for somebody applying for new cover.
Mortality risk increases with age, so the same level of new protection will generally cost more at 50 than at 30.
Our guide to why life insurance becomes more expensive as you get older explains how age interacts with health, term and cover amount.
That is particularly relevant where someone deliberately chooses a short policy today on the assumption that they can simply extend it later.
They may be able to obtain replacement cover.
But the future application would generally be assessed using their future age and health.
Be careful when replacing an established policy
This is one of the most important practical consequences.
Someone may have taken life insurance out at 30 when they were healthy.
Fifteen years later, they might see a new product advertised and consider cancelling the original policy.
But the original cover was accepted on the basis of their health and circumstances at the time.
A replacement application at 45 will normally be based on their health at 45.
If they have since developed diabetes, high blood pressure, heart problems or another medical condition, replacement cover might:
- cost more;
- require additional medical evidence;
- be offered on different terms;
- be postponed; or
- in some circumstances, be declined.
Our guide to changing or increasing existing life insurance explains why old cover should not normally be cancelled until any replacement policy has been fully accepted and is in force.
An older policy can sometimes be more valuable than its monthly premium initially suggests.
The amount of cover matters as much as the term
Longevity planning should not distract from another important question: how much money would actually be needed if a claim happened?
The answer might include:
- outstanding mortgage debt;
- other debts;
- childcare;
- household bills;
- education costs;
- funeral expenses;
- replacement income; and
- financial support for a surviving partner.
Savings, pensions and employer death-in-service benefits can then be considered against those needs.
Our guide to how much life insurance you need explains why simply covering the mortgage can sometimes leave a substantial family-income gap.
For example, clearing a £200,000 mortgage would remove a major monthly expense.
But it would not pay for:
- food;
- energy;
- childcare;
- council tax;
- transport; or
- everyday family spending.
The right plan therefore considers both how much cover is required and how long that need lasts.
Mortgage protection may reduce as the debt reduces
Some financial needs naturally decline.
A repayment mortgage is a good example.
If somebody borrows £250,000 today and steadily repays the capital over 25 years, the amount outstanding should generally reduce.
Decreasing-term life insurance is designed with that type of liability in mind.
The level of cover falls over time, broadly reflecting the idea that the financial exposure is getting smaller.
Our guide to decreasing-term life insurance for mortgage protection explains how this differs from level cover.
Again, the principle is matching the insurance to the shape of the risk rather than simply buying as much cover for as long as possible.
Retirement changes the calculation
For some families, retirement is a natural point at which life insurance needs reduce.
A household approaching retirement may have:
- repaid the mortgage;
- financially independent children;
- fewer debts;
- pension income;
- substantial savings; and
- less reliance on employment income.
In that situation, the financial consequences of an early death may be much smaller than they were 20 years earlier.
That does not mean everybody stops needing insurance at retirement.
A surviving partner may still depend on income that reduces after the first death.
There may be later-life debt, dependent relatives, business interests, funeral costs or estate-planning needs.
But the reason for having life insurance should be reviewed rather than assumed to continue unchanged.
Living longer creates a different financial risk
Life insurance deals primarily with the risk of dying too soon.
Pensions and retirement savings address almost the opposite risk: living for a long time and needing income throughout that period.
An individual could potentially spend 20, 25 or even 30 years in retirement.
The latest ONS figures illustrate this clearly.
A 65-year-old female in the UK had an average remaining period life expectancy of 21.2 years in the latest tables, while the figure for males was 18.7 years.
Many people will live considerably longer than those averages.
That means later-life planning may need to consider:
- pension income;
- savings;
- inflation;
- housing;
- potential care costs;
- wills;
- powers of attorney; and
- financial support between partners.
Life insurance is only one part of that wider picture.
Longer lives make wills and powers of attorney more important too
Financial planning is not only about accumulating enough money.
People also need to consider what happens if they live to an older age but become unable to manage their own affairs.
A will deals with what happens after death.
A lasting power of attorney can allow trusted people to make certain decisions where somebody loses capacity during their lifetime.
Neither replaces life insurance, and life insurance does not replace either of them.
Likewise, pensions, emergency savings and insurance perform different jobs.
A robust family plan may therefore combine several elements rather than expecting one product to solve every risk.
Review life insurance when circumstances change
Life insurance does not need constant adjustment because a new life-expectancy statistic has been published.
But it is sensible to review cover after important changes such as:
- having a child;
- buying or moving home;
- increasing a mortgage;
- marriage or separation;
- changing jobs;
- losing workplace benefits;
- becoming self-employed;
- taking on new debt;
- children becoming independent; or
- approaching retirement.
The question should remain consistent:
If I died today, what financial problem would this policy solve?
If the answer has changed, the cover may need reviewing.
For a broader starting point, our Life Insurance Explained section covers policy types, underwriting, mortgage protection, family needs and changing existing cover.
Life expectancy is context, not a prediction
The latest longevity evidence is useful because it shows how financial planning continues to evolve.
People need to prepare for the possibility of living for decades after retirement.
At the same time, families need to consider what would happen if an income-earner, parent or partner dies much earlier than expected.
Those are different risks and require different tools.
Life insurance addresses the second.
The aim should not be to insure somebody for their predicted lifespan.
It should be to protect the years in which their death would create a financial problem for somebody else.
That usually means matching the amount and duration of cover to mortgages, children, household income and other real financial dependencies — and allowing the protection to end when those risks genuinely disappear.
