Quick answer

What is life insurance?

  • In short: life insurance pays a tax-free lump sum to your family or estate if you die while the policy is in force.
  • How it works: you pay a monthly premium; in return the insurer promises an agreed payout to your chosen beneficiaries.
  • Two main types: fixed-length term cover, and lifelong whole-of-life cover that is guaranteed to pay out eventually.
  • Who it is for: anyone with a mortgage, children or other dependants who rely on their income.

How it works

Premiums, payouts, beneficiaries and trusts

When you take out a policy you choose a cover amount (the sum assured) and a term, then answer health and lifestyle questions. The insurer uses these to set your premium — the monthly amount you pay to keep the cover in force. If you die during the term and the policy is valid, the insurer pays the agreed lump sum.

By default the payout goes to your estate, which can mean it is delayed by probate and potentially counted for inheritance tax. Writing the policy in trust is a common, usually free option that names your beneficiaries directly, so the money is generally paid to them faster and outside your estate for inheritance tax. Most life insurance payouts are free of income and capital gains tax.

Cost

What life insurance costs in general terms

There is no single price — your premium is built from your personal details. As a rule of thumb, the younger and healthier you are when you apply, the cheaper cover is, and term cover is generally far cheaper than whole-of-life. For a healthy non-smoker, basic level term cover often starts from just a few pounds a month, rising with age, the cover amount and any health factors. Life insurance premiums are not subject to Insurance Premium Tax, unlike many general insurance products.

Who needs it

Who life insurance is for

Life insurance is most valuable when other people depend on your income or would inherit debt if you died. That typically means people with a mortgage, children or a partner who relies on what you earn. If you are single with no dependants and no debts that would pass to others, you may need little or none. Many people already have some death-in-service cover through work, which is worth checking before deciding how much extra to arrange. Explore the life insurance hub for guides by age, health and cover type.

Common questions

What is life insurance: FAQs

Life insurance is a contract where you pay a regular premium and the insurer pays an agreed tax-free lump sum to your family or estate if you die while the policy is in force. It is designed to replace your financial contribution so dependants are not left struggling.
If a valid claim is made, the insurer pays the sum assured to your beneficiaries or estate, usually as a single lump sum. If the policy is written in trust, the money is generally paid directly to the named beneficiaries, which can be faster and outside your estate for inheritance tax.
Term cover lasts for a fixed period and only pays out if you die within it, so it is cheaper and suits mortgage or family protection. Whole-of-life cover lasts as long as premiums are paid and is guaranteed to pay out eventually, so it costs more and is often used for funeral or estate planning.
Level cover keeps the same payout throughout the term. Decreasing cover reduces over time and is usually matched to a repayment mortgage. Increasing cover rises over time to help offset inflation, so the real value of the payout is better preserved.
The payout itself is normally free of income and capital gains tax. However, if it is paid into your estate it can be counted for inheritance tax. Writing the policy in trust is a common, usually free way to keep the payout outside your estate for inheritance tax purposes.
It depends on whether anyone relies on your income. If you have a mortgage, children or a dependent partner, cover can protect them from financial hardship. If you have no dependants and no debts that would pass to others, you may need little or none. Checking any cover you already have through work is a sensible first step.
