The Underinsurance Puzzle: Why Millions of Brits are at Risk

We’re a nation of insurance buyers. Every year we renew our car insurance, insure our homes and their contents, take out cover for our pets, and add protection for our phones, laptops and tablets. There are around 44 million motor insurance policies in the UK and roughly 35 million home insurance policies. Gadget insurance alone rose to 8.46 million policies in 2024, up from 7.87 million the year before.

Most of us don’t think twice about it. If the car is written off, the boiler floods the kitchen or the phone ends up at the bottom of a swimming pool, we expect to be covered. It’s simply what sensible people do.

So here’s the puzzle. When it comes to protecting the things that matter most, we suddenly go quiet. That means our ability to earn an income, our family’s security if we die, and financial support if we’re diagnosed with a serious illness. We’ll insure a £1,000 phone without hesitation, but often leave a lifetime of earnings unprotected.

The result is that millions of British families are one diagnosis, accident or bereavement away from serious financial difficulty. And most of them don’t realise it until it’s too late to do anything about it.

The Numbers Don’t Lie

The protection gap is staggering. While 75% of homeowners have buildings or contents insurance, protection for ourselves tells a different story:

• Only 28-35% of UK adults have life insurance
• Just 14% have income protection
• Even fewer have critical illness cover

Many of us are more likely to insure our £400 television than our £40,000 income. We’ll pay £12 per month to insure pets, but hesitate at similar amounts to protect our family’s future.

The Risk Is Real and It’s Closer Than You Think

If you’re thinking “it won’t happen to me,” the statistics say otherwise. Serious illness striking only the elderly is dangerously outdated thinking.

• 45% of all critical illness insurance claims in the UK are now paid to people under the age of 50
• 22% of critical illness claims are made by people under 40
• Around 35,000 cases of cancer are diagnosed annually in people aged 25-49 – that’s nearly 100 people every single day
• One in five heart attacks occur in people under the age of 55
• Around one in four strokes happen to people of working age

Perhaps most alarming of all, 35% of the UK working-age population is now living with at least one long-term health condition. This isn’t about other people. This is about us, our colleagues, our friends, our families.

Why We Keep Putting It Off

If the risks are real, why do so few of us have protection? The psychology is deeply human. Optimism bias is powerful. We believe we’re less likely than average to experience these events. We avoid unpleasant topics. Thinking about mortality or illness isn’t comfortable, so we promise to “sort it out next month.” We prioritise the urgent over the important. The broken boiler demands attention now. Protection can wait. Except it can’t. It feels complicated. Life insurance, income protection, critical illness – where do you start? Perceived complexity creates inertia that too often leads to inaction.

The Real Cost of Being Unprotected

The consequences aren’t abstract. They’re devastatingly real. Four in ten people are financially worse off after cancer, losing an average £860 monthly. More than half of working-age adults who survive major illness never see their income return to previous levels.

If your income dropped £860 per month tomorrow, what would happen? Could you pay the mortgage? Cover bills? Maintain your lifestyle? For most, the answer is no. Without protection, many families raid pension pots, remortgage homes, or watch savings evaporate. Financial worry compounds the overwhelming challenge of illness – adding untold financial stress to an often already traumatic situation.

It’s More Affordable Than You Think

Protection insurance is almost certainly cheaper than you imagine. Average life insurance costs around £26 per month. Income protection and critical illness often start from around £20 monthly. That works out at around £5 to £6 a week, roughly the price of a takeaway coffee and a pastry.

Your quote depends on age, health, and circumstances. For a healthy non-smoker in their 30s, a basic level of cover can cost less than a monthly phone bill. The question isn’t whether you can afford it – it’s whether you can afford not to have it.

What You Actually Need

Three core types form the foundation of financial security:

• Life Insurance pays a lump sum if you die during the policy term. Essential if anyone depends on your income. The payout clears mortgages, replaces income, and maintains your family’s standard of living.
• Income Protection replaces a significant proportion of income if you’re unable to work due to illness or injury. Unlike minimal statutory sick pay, it can continue until you return to work or retire, depending on the policy. Some policies pay out for a set period, such as one, two or five years. Many advisers consider this the most important protection product.
• Critical Illness Cover pays a tax-free lump sum upon diagnosis of serious illness (cancer, heart attack, stroke, etc.). Use it for anything: clearing debts, funding treatment, adapting your home, or simply providing breathing space.

Which you need depends on circumstances. Mortgage? Life insurance is crucial. Self-employed or lack sick pay? Income protection vital. Young family? Critical illness provides a safety net. It’s also worth checking what you already have. Many employers provide death-in-service benefit or enhanced sick pay, and some state support may be available. Knowing what’s already in place helps you avoid paying for cover you don’t need, and shows you exactly where the gaps are.

The Time to Act Is Now

You can’t get income protection once you’re signed off sick. You can’t buy critical illness cover after diagnosis. And you can’t purchase life insurance for someone who’s already died. Protection insurance only works if you have it before you need it.

There’s another crucial reason not to delay: the younger and healthier you are, the cheaper it is. Wait five years, and premiums increase. Develop a health condition in the meantime, and you might face exclusions or higher costs. Put it off indefinitely, and you might become uninsurable.

Every week without the right protection is another week your family is exposed to a risk that could be covered, often for less than you’d expect. It’s another week of unnecessary risk. And it’s another week where you could have had peace of mind but chose to postpone it instead. Don’t be another statistic. Don’t be the person who wishes they’d sorted this out before it was too late. Don’t let your family discover, at the worst possible moment, that you left them financially exposed.

The puzzle of underinsurance doesn’t have a complicated solution. It just requires you to take action. Get quotes online, do some research or speak with a financial planner who can get you insured. It’s crucial to understand what you need and what it costs. Then make an informed decision. Your future self (or the people you love) will thank you for it one day.
