Life insurance is one of the most important financial safety nets a family can have, yet it is surrounded by jargon and misunderstanding. At its heart it is simple: it pays out money if you die, to help the people who depend on you. This guide explains how life insurance works, the main types, and who really needs it.
What life insurance is
Life insurance is a policy that pays out a sum of money, usually a tax-free lump sum, if you die while covered. You pay a regular premium, and in return the insurer promises to pay your chosen beneficiaries if the worst happens. The purpose is to protect the people who rely on you financially, so that your death does not also become a financial crisis for them, on top of the emotional loss.
Who really needs it
The simplest test is to ask whether anyone would suffer financially if you died. If you have a partner, children, or others who depend on your income, or a mortgage or debts that would fall on someone else, life insurance is likely worth having. If you are single with no dependants and no debts that would pass to others, you may not need it, a question explored in our guide to how much cover you need.
How it works
When you take out life insurance, you choose an amount of cover, known as the sum assured, and a length of time or basis for the cover. You answer questions about your health, lifestyle and sometimes occupation, which determine your premium. As long as you keep paying the premiums and the policy is in force, your beneficiaries will receive the agreed sum if you die. The money can be used for anything, from clearing a mortgage to covering everyday living costs.
The main types of cover
Life insurance comes in two broad types. Term life insurance covers you for a fixed period, such as 25 years, and only pays out if you die within that term. Whole of life insurance covers you for your entire life and pays out whenever you die. Term cover is cheaper and suits most families protecting against a specific period of risk, while whole of life is more expensive but certain to pay out, as our guide to term versus whole of life explains.
Life insurance and your mortgage
A very common reason people buy life insurance is to cover their mortgage, so that if they die, the loan is paid off and their family can stay in the home. This is often arranged as decreasing term cover that falls in line with the mortgage balance. It is not compulsory to have life insurance for a mortgage, but many people consider it essential, since the home is usually a family's largest debt and most important asset.
Life insurance versus life assurance
The words insurance and assurance are often used interchangeably, but there is a traditional distinction. Life insurance usually refers to term cover, which may or may not pay out depending on whether you die within the term. Life assurance traditionally refers to whole of life cover, which is certain to pay out eventually. The terminology is not always used consistently, so what matters is understanding whether a policy covers a fixed term or your whole life, rather than the label.
What affects the cost
Your premium depends mainly on the risk to the insurer, which means your age, your health, whether you smoke, your lifestyle and sometimes your occupation, along with the amount and length of cover. The younger and healthier you are when you take out cover, the cheaper it tends to be, which is why buying earlier often locks in a lower price. Being honest about your health is essential, for reasons explained below.
The importance of honesty
When you apply, you must answer the health and lifestyle questions fully and accurately. The single biggest reason life insurance claims are declined is non-disclosure, where someone did not tell the insurer something relevant when they applied. Getting cover is not worth much if a claim is later refused because of an inaccurate application, so take care to disclose everything asked, even things that seem minor or unflattering. Accurate information protects your family.
Do claims actually get paid?
A common worry is whether insurers really pay out. The reassuring answer is that the vast majority of claims are paid: across the industry, around 97 to 98 per cent of protection claims are paid each year, and insurers paid out billions of pounds to families in recent years. The small proportion declined usually come down to non-disclosure or claims that fall outside the policy terms, which underlines the value of an accurate application and the right cover.
Related types of protection
Life insurance is part of a wider family of protection products. Critical illness cover pays out if you are diagnosed with a serious illness, while income protection pays a regular income if you cannot work due to illness or injury. These can be bought alongside or instead of life insurance, depending on what you are protecting against, as covered in our guides to critical illness cover and income protection.
When it might not pay out
Life insurance is reliable, but it is not unconditional. A claim can be refused if you did not disclose relevant health or lifestyle information when you applied, if the policy had lapsed because premiums stopped, or if the cause of death falls under a specific exclusion. Many policies also have a short initial period during which death by suicide is not covered. Understanding these limits, and keeping your policy in force and your application accurate, is what ensures it does its job.
Keeping cover in force
For a policy to pay out, it must be active, which means keeping up the premiums. If payments stop, cover can lapse and a later claim would fail, so it is important to maintain the policy, especially as it is often most needed years after it was taken out. If your circumstances change and a policy becomes unaffordable, speak to your insurer about options rather than simply cancelling, since losing cover can be costly to replace later at an older age.
In short
Life insurance pays a usually tax-free lump sum to your loved ones if you die, protecting those who depend on you financially. Most people with dependants, a mortgage or shared debts should consider it. The main choice is between cheaper term cover for a fixed period and whole of life cover that always pays out. Apply honestly, since non-disclosure is the main reason claims are declined, and buying younger usually costs less.
