What is life insurance?

Life insurance is protection that will provide money to your loved ones and dependants after you have passed away. The money can be used for anything they need to pay out for, such as:

  • Mortgage or rent

  • Household bills

  • Childcare or university fees

  • Funeral costs

Who needs life insurance?

Anyone who has financial dependants should think about having life insurance. Ask yourself if you were to die out of the blue, how would those you leave behind pay for their bills.

Would there be enough money to cover your share of the mortgage, for example, or would they struggle to meet the costs of everyday bills. If you have life insurance in place, this can be used to cover the money you usually take home.

It's particularly important for those who want to ensure that their family can continue to afford ongoing costs like mortgage payments, bills, childcare, and education expenses.

Types of life insurance policies

There are lots of different types of life insurance, including the following:

Types of life insurance

Level term life insurance

Level-term life insurance is where the amount of money paid out in death stay the same throughout the policy term. This means that beneficiaries receive a guaranteed payout upon the policyholder's death, which can be used for any costs at their discretion.

Decreasing term life insurance

For those focused on ensuring their mortgage is taken care of, decreasing-term life insurance is designed to pay out a lump sum that reduces over time, typically in line with the reduction of your mortgage debt.

Whole of life insurance

A whole of life policy, also called life assurance, offers lifetime coverage and guarantees a fixed payout to beneficiaries, providing peace of mind that your loved ones will be financially supported no matter when you pass away.

This is usually one of the most expensive policies to buy, as it providers cover throughout your life.

Joint life insurance

A joint life insurance policy is a practical solution for couples, paying out upon the first death and ending after the first claim, ensuring the surviving partner receives the support they need.

Over 50s life insurance

Over-50s life insurance is tailored for older individuals, offering guaranteed coverage without medical checks and covering most pre-existing conditions.

Key benefits of life insurance

  • Income replacement: Life insurance compensates for the lost salary of the deceased

  • Mortgage payoff: It ensures the mortgage is covered, so the family home is secure

  • Funeral costs: Many policies can cover funeral expenses before the lump sum payout

  • Debt clearance: Life insurance pays off the policyholder's debts, ensuring beneficiaries receive the remainder

  • Tax benefits: Having your policy 'written in trust' can protect the payout from inheritance tax

  • Additional benefits: Some policies offer extra perks like bereavement support or financial advice services

How much does life insurance cost?

You can get life insurance from just £21.78^ per month if you're aged between 18 and 49. However, prices may vary based on your personal circumstances and what type of policy you choose.

When to consider life insurance?

Major life changes such as cohabitation, marriage, home buying, having children, or job transitions are key moments to consider life insurance. It's not just about providing for your family in the event of your death; it's about ensuring stability during life's unpredictable moments.

What happens if I don't have life insurance?

If you don't have life insurance and you pass away, your loved ones may face financial difficulties managing expenses like mortgage payments, bills, or childcare without the help of a lump sum from a policy.

However, if you have no financial dependents, you might not need life insurance. Some people may also have alternative coverage like a death in service benefit through their employer or income protection insurance.
