Do You Actually Need Life Insurance? A UK Guide for Every Life Stage

Life insurance pays out a lump sum to your chosen beneficiaries when you die. That's it. It's not an investment, it's not a savings plan (unless you buy a whole-of-life policy, which is a different product and usually poor value), and it doesn't pay out if you lose your job or get ill (that's income protection or critical illness cover). A standard term life insurance policy covers you for a set period — 10, 20, 25, or 30 years. If you die during that term, it pays out. If you survive the term, it doesn't pay anything and the policy ends. It sounds morbid, but the purpose is practical: replacing your income so the people who depend on it — your partner, your children — can continue to pay the mortgage, bills, and living costs without you.

You need life insurance if: you have a mortgage and a partner or family who would need to keep paying it; you have children who depend on your income; you're the sole or main breadwinner in your household; or your partner would struggle financially without your contribution. The classic scenario is a couple with a £250,000 mortgage and two young children. If one partner dies, the survivor needs to cover the mortgage and all household costs on a single income — plus potentially pay for childcare they previously didn't need. A life insurance policy equal to the mortgage amount plus 5 to 10 years of living costs provides that safety net. Many mortgage lenders don't require life insurance, but it's strongly recommended. Some won't lend without it.

If you're single with no dependants, no one suffers financially from your death — so life insurance is usually unnecessary. Similarly, if you're in a couple where both partners earn enough to cover all costs independently, the financial need is lower (though it might still help cover the mortgage). If you have no debts, significant savings or investments, and your partner would inherit enough to maintain their lifestyle, you're likely self-insured already. Retirees with paid-off mortgages and grown children often don't need life insurance either — the people who depended on their income no longer do. The exception is inheritance tax planning, but that's a niche use case for larger estates.

There's no magic formula, but a common approach is: outstanding mortgage balance + 10 years of your annual income. So if you have a £200,000 mortgage and earn £35,000, you'd want roughly £550,000 of cover. That gives your family enough to clear the mortgage and replace your income for a decade while they adjust. Another approach is to work backwards from your family's actual expenses: monthly bills plus mortgage plus childcare multiplied by the number of years until your youngest child is financially independent. Be realistic — underinsuring to save £5 a month defeats the purpose. A £100,000 policy sounds like a lot until you realise it only covers the mortgage and two years of bills.

Life insurance is cheaper than most people think, especially for young, healthy non-smokers. A 30-year-old non-smoker can get £300,000 of level term cover for 25 years for around £10 to £15 per month. A 40-year-old might pay £20 to £35 for the same cover. Smokers pay roughly double. The cost depends on your age, health, smoker status, the amount of cover, and the policy term. Decreasing term cover (where the payout reduces over time, designed to match a repaying mortgage) is cheaper than level term cover (where the payout stays the same throughout). Use comparison sites like CompareTheMarket, MoneySupermarket, or a broker to get multiple quotes. Don't just go with the cheapest — check the insurer's claims acceptance rate and customer reviews.

This is the most important and most overlooked step. If you put your life insurance policy in trust, the payout goes directly to your beneficiaries without passing through your estate. That means it's paid faster (often within weeks rather than months) and it doesn't count toward inheritance tax. Without a trust, the payout becomes part of your estate, which could push it above the £325,000 inheritance tax threshold. Setting up a trust is free with most insurers — they provide a trust form when you take out the policy. It takes 10 minutes to complete but could save your family tens of thousands in tax and months of waiting. Every life insurance policy should be written in trust. Every single one. Ask your provider when you buy.

Life insurance isn't set-and-forget. Review your cover when major life events happen: getting married, having a child, buying a house, changing jobs, getting divorced, or paying off your mortgage. Each of these changes might mean you need more cover, less cover, or different cover. A policy you took out at 25 with no dependants might be completely wrong for your situation at 35 with two kids and a mortgage. Similarly, once your mortgage is paid off and your children are adults, you might not need the policy at all.
