Do I Need Life Insurance? How to Decide

You need life insurance if your death would leave someone else facing a financial gap: a partner who couldn't cover the mortgage alone, children who'd lose a chunk of household income, or a co-signer left holding a joint loan. If nobody relies on your earnings and no debt would transfer to somebody else when you die, life insurance is far less urgent, and in some cases unnecessary.

The honest answer sits somewhere between those two extremes for most people. A 32-year-old renting alone with no dependants has a very different answer to a 38-year-old with a £180,000 mortgage, a partner on maternity leave, and two children under ten. The test isn't your age or your health, it's whether your death would create a financial problem for someone who depends on you now. Research cited by the Money and Pensions Service suggests roughly 1 in 3 UK adults with dependants currently have no life insurance in place, which means a significant share of families are carrying risk they haven't quantified. Working through the checklist below takes under a minute and gives you a clearer answer than guessing.

Answer these five questions honestly. The more times you answer yes, the more life insurance is likely worth considering for your situation.

1. Do you have a mortgage or debt shared with someone else? If your name is on a joint mortgage or loan, your death could leave the other person responsible for the full balance.
2. Do you have children or a partner who relies on your income? Even a second income covering household bills, childcare, or rent counts here.
3. Would your funeral costs be a burden on someone else? The average UK funeral now costs upward of £9,000, according to SunLife's Cost of Dying research, and that bill typically falls on whoever is left to arrange it.
4. Do you have savings that could realistically replace years of lost income? Most households don't have six figures sitting in an account, so this is usually a no.
5. Does your employer's death-in-service benefit fully replace your income? Many schemes pay two to four times salary, which sounds generous but rarely covers a mortgage and years of childcare on top.

Three or more "yes" answers is a strong signal that a policy is worth pricing up rather than putting off.

Some circumstances make life insurance close to essential rather than optional. If any of the following apply to you, cover is worth prioritising over most other financial admin on your list.

• Homeowners with a mortgage: If you own a home with an outstanding mortgage and someone else would be left paying it, whether that's a partner or a family member who inherits the property along with the debt, life insurance for your mortgage is usually the single most important policy you can arrange. A typical UK mortgage balance sits above £140,000, and few households could absorb that overnight.
• Parents and people with dependent children: Raising a child to 18 is commonly estimated at £160,000 to £200,000 across various UK cost-of-a-child studies, covering everything from food and clothing to childcare and school costs. If you died, that financial responsibility wouldn't disappear, it would fall entirely on your partner or another guardian.
• Couples who share household costs: Even without children, two incomes supporting one household (rent, bills, a car, holidays) means losing one income can be as damaging as losing a job with no notice. Joint life insurance for couples is often cheaper than two single policies and pays out on the first death.
• Self-employed people and business owners: There's no employer death-in-service payout if you work for yourself, and a business often owes money, has ongoing contracts, or depends entirely on your input to keep trading. Life insurance if you're self-employed fills a gap that employees get automatically.
• Anyone with debts that would pass to someone else: Personal debt doesn't automatically disappear when you die. Joint loans, guarantor arrangements, and some types of unsecured credit can become another person's problem at the worst possible time.

Life insurance isn't automatically necessary for everyone, and paying for cover you don't need is still a waste of money even at a low monthly cost. You may be able to skip it, or at least deprioritise it, if you fit one of these profiles.

• Single with no dependants and no shared debt: If nobody would be financially worse off because of your death, the core reason for holding cover doesn't apply. This is common for younger renters without children or a partner relying on their income.
• Retired with a paid-off mortgage and enough pension income: Once your mortgage is cleared and your pension or savings would comfortably support a surviving partner, the financial gap that life insurance exists to fill has largely closed. Over-50s cover is sometimes still used here, but usually to cover funeral costs rather than replace income.
• Enough savings and assets to cover final expenses outright: If you could self-insure, meaning your estate could cover funeral costs, clear any debts, and leave dependants financially secure without a payout, a policy becomes a nice-to-have rather than a necessity.

Even in these cases it's worth double-checking your numbers rather than assuming you're covered. Pension income and savings pots often look healthier on paper than they do once inflation and long-term care costs are factored in.

These are the specific situations readers ask about most often. Each answer below is short enough to skim, but detailed enough to actually help you decide.

• I'm single with no dependants? Probably not a priority yet. If nobody relies on your income and no debt would transfer to someone else, life insurance isn't doing much financial work for you right now. Revisit the question when your circumstances change, such as moving in with a partner or taking on a joint mortgage.
• I have a workplace pension? A pension pays out when you retire, not when you die young. Most workplace pensions do include a small death benefit, but it's rarely enough to replace years of lost income for a partner or children, so a pension alone doesn't remove the need for cover.
• I already have death-in-service cover? This is a good start, but check the multiple. Two to four times salary sounds substantial until you compare it against a mortgage balance and 15 years of childcare costs. It also usually ends the moment you leave that employer, so it isn't portable cover.
• I'm renting rather than buying? You don't have a mortgage to protect, but you may still have dependants relying on your income to cover rent, bills, and daily costs. The absence of a mortgage doesn't mean the absence of financial dependency, so the answer usually comes down to who relies on your earnings.
• I'm a stay-at-home parent and don't earn? Yes, arguably more than most people realise. Replacing everything an unpaid parent does, from childcare to running the household, would cost a working family a genuine sum if they had to pay for it. Family income benefit cover is often a cost-effective way to protect this contribution specifically.

Without a payout, the costs that a death creates don't go away, they land on whoever is left behind. Below are the most common financial pressures a family faces, based on typical UK figures cited by SunLife's Cost of Dying report and standard mortgage and income data.

A funeral alone now averages over £9,000 once a service, venue, and send-off costs are included. Add a mortgage balance that hasn't been paid off, months or years of lost household income, and ongoing childcare costs, and the total gap can run into six figures surprisingly quickly. Families without cover often end up selling the family home, taking on additional debt, or relying on wider family support to bridge the shortfall. None of these are quick or comfortable fixes at a time when the household is already dealing with grief. A partner earning £30,000 a year who died at 40 could represent well over half a million pounds of lost future income alone, even before funeral costs or outstanding debts are added to the total.

Life insurance is consistently cheaper than most people expect, particularly if you arrange it while you're young and healthy. Premiums are based mainly on your age, health, smoker status, the amount of cover, and how long you need it for, which is why how much life insurance costs varies so widely between a 25-year-old and a 55-year-old buying the same sum assured.

As a rough guide, a non-smoker in their 20s can often secure £150,000 of level term cover for the price of a coffee a week, while the same policy taken out in your 50s costs noticeably more because age and health risk both increase. Smokers typically pay significantly more than non-smokers for identical cover, sometimes double, which is worth factoring in if you're weighing up when to apply. Waiting doesn't just cost you money, it can cost you insurability altogether if a health condition develops in the meantime.

The best time to arrange life insurance is before you actually need it, which usually means acting at one of a handful of predictable life events rather than waiting for a health scare to prompt you. Premiums are locked in based on your age and health at the point you apply, so the earlier you sort cover, the cheaper it typically stays for the life of the policy.

• Taking out a mortgage: the moment you take on mortgage debt is the moment that debt needs protecting.
• Having a child: a new dependant changes the financial stakes overnight.
• Getting married or moving in together: shared finances usually mean shared risk.
• Starting a business: self-employment removes any employer safety net.
• Turning 30 or 40: premiums rise with age, so reviewing cover at these milestones, before your next birthday if possible, can lock in a lower rate.

If you're unsure how much you'd actually need at any of these points, it's worth taking the time to work out how much cover you need rather than guessing a round number.

Life insurance only pays out when you die, which means it does nothing to help if you're seriously ill or unable to work but still alive. That's where life insurance vs critical illness cover becomes a genuinely different question rather than a rewording of the same one.

Critical illness cover pays a lump sum if you're diagnosed with a specified serious illness, such as cancer or a heart attack, regardless of whether you survive. Income protection goes further, paying a regular monthly income if you can't work due to illness or injury, for as long as your policy term and definition allow. Many households need a combination rather than a single product: life insurance to protect dependants if you die, and either critical illness or income protection to protect your income if you don't but can't work. Applying with a pre-existing health condition doesn't automatically rule any of these out, life insurance with a pre-existing condition is available from specialist providers even when standard applications are declined.

If you've read this far and you're still not certain, work through these three steps in order. They take most people under ten minutes and turn a vague worry into a specific number.

1. List who depends on you financially. Include a partner, children, anyone you financially support, and anyone named on a joint mortgage or loan with you.
2. List what they'd need covering. Add up the mortgage balance, other debts, funeral costs, and however many years of income replacement or childcare costs feels realistic for your situation.
3. Subtract what's already covered. Deduct savings, death-in-service benefits, and any existing policies from your total.

Whatever's left is the gap life insurance should fill. Working through this calculation properly, rather than picking a round number because it sounds sensible, is the single biggest factor in whether a policy actually protects your family the way you intended. It's a five-minute exercise that's worth repeating whenever your circumstances change, such as moving house, having another child, or paying off a large chunk of your mortgage early.
