King George V initiated the custom of sending congratulatory letters to centenarians in 1917, but he only reached out to 24 individuals. He was reportedly concerned that if more people began living to 100, he’d struggle to keep up with the signatures. Fast forward to today, and what began as a simple gesture has transformed into an extensive operation—perhaps influenced by the King’s impatience with faulty fountain pens.
The number of people aged 100 and over is on the rise in the UK. According to recent data from the Office for National Statistics (ONS), by 2024, there will be 16,600 centenarians in the UK, a significant jump from 8,300 in 2004. While longevity is generally worth celebrating, the latest figures on healthy life expectancy reveal some concerning trends.
Back in 2011, men were projected to remain healthy until approximately 63 years old, while women were expected to stay healthy until around 64. Currently, the healthy life expectancy for both groups has decreased to just 61 years. This highlights a troubling fact: even as we live longer, our quality of life isn’t necessarily improving. This situation poses implications for state pension costs and pressures on the NHS, with heightened expenses translating into a longer duration of care. The reality is that we will often need to cover these additional years ourselves.
Many of us, however, seem to plan our finances as if we’ll be in the grave by 85. We consider retirement as a brief phase—only saving for about 15 years and treating investment growth as irrelevant after 60. But retirement can stretch for more than three decades. The primary financial threat, it seems, is simply outliving our savings.
In essence, our longer lives necessitate a re-evaluation of financial expectations. Here are five strategies for preparing for an extended life.
1. Consider that financial stability may extend life
The retirement landscape is shifting from defined benefit pensions—where employers shoulder the risk—to defined contribution pensions, placing the responsibility squarely on us. This shift means we now face significant challenges such as longevity, inflation, and market fluctuations during retirement.
Many retirement plans operate on the assumption that your income will suffice for around 30 years. If you retire at 65, the idea is your funds should last until about 95. This principle is often linked to the “4 percent rule”, which suggests withdrawing 4 percent from a diversified portfolio while accounting for a 2 percent annual growth to counter inflation. Historically, this formula was intended to cover a 30-year span.
Given the average life expectancy at 65, men should plan to live into their mid-80s and women into their late 80s. Still, “average” can be a deceptive term. A 65-year-old woman has about a 25% chance of reaching her mid-90s and a 6% chance of hitting 100. Health and wealth usually extend life expectancy.
The previous advice to minimize risk by shifting into bonds as you reach your 60s doesn’t quite hold up anymore. The combination of inflation and increasing longevity makes for a challenging scenario. Long-term investments in growth may feel uneasy, but running out of money by 87 is a valid concern.
New research indicates that retirees are adopting a “flex and fix” strategy—taking early withdrawals and purchasing annuities later to secure stable income. That’s wise, but starting too early can be risky if inflation rises and your retirement spans decades.
One interesting find came from Annie Coleman at Stanford University, who tested an online calculator that factors in health and lifestyle for life expectancy. She predicted living to 102. I tried it as well and ended up with 88—perhaps indicative of my lifestyle habits.
I don’t have a crystal ball, but it seems many of us are meticulously budgeting our finances while neglecting a stress test for the length of our lives. This doesn’t mean living frugally; in reality, some older folks tend to save excessively. It’s more about planning for over 35 years and ensuring your expenses are safely managed into old age.

2. Ensure your income mirrors actual living
Recent ONS data on healthy life expectancy paints a sobering picture of longevity in Britain. We’re not just living longer; we’re also living with various illnesses and care requirements, which significantly impacts our finances and policymakers alike.
Post-retirement spending isn’t linear but rather follows a curve often referred to as the “post-retirement spending smile.” Spending generally peaks during early retirement years, dips as mobility decreases, and then rises again with increased health needs and care costs.
It’s crucial to differentiate between your healthy phase and the potential care phase down the line. Care can be long-lasting and costly, but very few specialized savings products exist in the UK to address these needs, forcing reliance on locked savings and property assets.
The risk is that many of us might eagerly plan an exciting trip at age 70 while underestimating potential care requirements at 92. The uncertainty surrounding nursing care is significant; we know that many will ultimately need it, but not everyone does, which makes planning ahead more complex.

3. Make smart investments to capitalize on the longevity trend
Longevity isn’t just a personal finance concern—it presents a significant investment opportunity as well. An aging population naturally increases the demand for healthcare and related sectors.
The care economy, for instance, is predicted to expand considerably. Projections based on 2018 data suggest that by 2035, the number of older individuals requiring care could be 90% greater than in 2015, with increasing needs for round-the-clock support.
The demographic shifts influencing care requirements are reshaping capital markets, establishing longevity as a pivotal investment theme. Investors can engage with this trend through health and demographic funds, specialized investment trusts, and real estate ventures focused on care facilities and senior housing. Beyond physical properties, there exists a substantial silver economy where individuals aged 55 and older control significant wealth and are driving growth in sectors like travel, health, and leisure.
Some might view this as mere growth investing—but demographics present one of the few predictive trends in market positioning. If you can’t evade the current wave, it’s wise to learn how to navigate it effectively.

4. Start supplemental pension work early
Postponing retirement can quickly enhance your financial standing, allowing for additional saving years and reducing withdrawals. However, real change isn’t about working indefinitely—it’s about working in a different capacity.
Consider this a portfolio-building tactic in your 40s and 50s. By engaging in consulting, teaching, or small business ventures, you can cultivate skills that are adaptable for future income.
Such trends are already apparent; individuals over 50 represent one of the fastest-growing segments of entrepreneurs. Research from Direct Line Group suggests around 740,000 UK pensioners hold a side job, while a Virgin Startup poll indicates one in four over-55s plan to launch their own business. A 2024 Continuum Survey found that four in ten adults intend to keep working during retirement to sustain their lifestyle.
Employers are also adjusting to this trend. For instance, EasyJet plans to launch a “Returnship” initiative for those over 50 and those shifting careers. The business benefits are becoming clear; experiments at DIY retailer B&Q and car manufacturer BMW reveal that older employees tend to be more productive, and research shows organizations with a higher percentage of workers over 50 often perform better.
Recruiters are increasingly valuing experience and thoughtful decision-making as valuable assets, especially as workforce shortages loom. A 2025 study found that cognitive abilities often peak during late middle age, around 55 to 60—right when many organizations begin to push out older employees.
When considering a lifespan of 100 years, the purpose of work changes. Rather than following a single career trajectory, a diversified portfolio is essential for sustaining income and maintaining your identity and connections over several decades.

5. Optimize your pension advantages
The simplest way to gear up for a future with 100-year lifespans is, unsurprisingly, the most mundane: save more.
If you’re employed, make sure you take full advantage of your employer’s contributions to pension plans—this is essentially free money. Don’t neglect the fact that annuities can be a tax-efficient investment choice, with pension contributions costing less for higher-rate taxpayers.
For those earning higher incomes, the tax framework can enhance the appeal of pensions. Once your income surpasses £100,000, tax-free allowances begin to diminish, creating a situation where your effective tax rate can hit 60% on incomes between £100,000 and £125,140. This scenario doesn’t encompass pension salaries, providing a compelling reason to use pensions effectively.
Maintaining longer lives is often celebrated as a demographic advance, but it also signals a financial transformation. We aren’t just living longer; we’re navigating a fundamental change in how we manage wealth. Retirement has shifted from being an endpoint to likely being a very long journey requiring ongoing expenditures alongside maintaining good health.
