Find out if mortgage life insurance or standard life insurance is suited to your financial and family needs.

Key takeaways

  • Mortgage life insurance ensures your home loan is paid off if you die within the mortgage term

  • For mortgage life insurance the policy value decreases as you pay down your mortgage so if you pass away during the term, your dependents receive a sum to cover the remaining mortgage

  • Level-term life insurance provides a fixed payout amount for a set duration, which can be used for various debts, not just the mortgage

  • For level-term life insurance the payout amount remains constant throughout the policy term

What is mortgage life insurance?

Mortgage life insurance, also referred to as decreasing-term life insurance, is a type of life insurance policy that pays off the remaining balance of a mortgage if the policyholder dies.

How does mortgage life insurance work?

You purchase the policy for a set period, ideally running alongside the length of your mortgage. As you gradually pay down your home loan, the value of your insurance policy decreases correspondingly.

In the event of your passing during this term, your dependents will receive a sum that covers the remaining mortgage, ensuring the family home is secure.

Questions to ask before getting mortgage life insurance:

Questions to ask before getting life insurance

Do I only want to cover my mortgage?

What’s your budget?

  • If affordability is key, mortgage life insurance might be better due to lower premiums

How much does mortgage life insurance cost?

The average cost of a decreasing term life insurance policy is currently £24.66^ . However, the cost will vary based on factors such as your age, health and lifestyle, and how much cover you require.

What’s the difference between mortgage life insurance and level term insurance?

There are several differences between mortgage life insurance and level term insurance, including:

Mortgage Decreasing Term Life Insurance

Level Term Life Insurance

Purpose

Designed to cover a repayment mortgage or other decreasing debt

Provides a fixed lump sum payment for dependents

Payout amount

Decreases over time, usually in line with the outstanding mortgage balance

Stays the same for the entire policy term

Premium costs

Generally cheaper premiums due to the decreasing payout and reduced insurer liability over time

More expensive premiums because the payout and cover remains the same throughout the term

Suitability

Homeowners with a repayment mortgage who only need to cover the mortgage balance

Individuals wanting to provide a fixed sum for family, debts, or other expenses

Flexibility

Less flexible—linked closely to a decreasing debt like a mortgage

More flexible—can be used for any purpose and doesn’t depend on debt

Payout

Matches the reducing liability over the mortgage term

Offers a consistent payout regardless of when death occurs during the term

Mortgage life insurance vs level term - which is right for me?

Choosing between mortgage life insurance and level term life insurance depends on your financial situation, dependents, and goals. Here’s a breakdown to help you decide:

Mortgage life insurance vs level term life insurance

Mortgage life insurance

Best For:

  • Homeowners with a repayment mortgage who want a policy that pays off the outstanding balance if they pass away

  • Those looking for a more affordable option, as premiums are generally lower due to the decreasing payout over time.

  • Individuals who prioritise covering a specific debt (like a mortgage) rather than leaving a lump sum for family or other purposes.

Level term life insurance

Best for:

  • Those looking to provide a fixed lump sum for dependents, regardless of when death occurs during the policy term

  • Individuals with interest-only mortgages or no mortgage who want financial security for their family (e.g., to cover living costs, education, or other expenses)

  • People who prefer flexibility in how the payout can be used

What are the pros and cons of mortgage life insurance?

Similar to other types of life insurance, there are pros and cons to weigh up with mortgage life insurance, including:

Pros

  • Premiums are generally lower compared to other life insurance types, as the payout decreases over time

  • Straightforward cover focused solely on mortgage protection

  • Guarantees that your home will be paid off, providing financial security for your loved ones.

  • Fixed term aligned with your mortgage term, so you’re not paying for coverage you don’t need

Cons

  • The payout reduces over time, which might not leave enough for other expenses or dependents

  • Designed only for mortgage repayment, offering little to no flexibility for other financial needs

  • Unlike other life insurance policies, it doesn’t provide a lump sum for dependents or cover other debts

  • The decreasing payout structure doesn’t match the static balance of an interest-only mortgage

  • If you’ve made changes to your mortgage (e.g., extending the term or borrowing more), the policy might not provide full cover unless you update it

What are the alternatives to decreasing term life insurance?

Here are some alternative life insurance policies to consider:

Alternatives to decreasing term life insurance

Level term life insurance

Best for:

  • Those looking to provide a fixed lump sum for dependents, regardless of when death occurs during the policy term

  • Individuals with interest-only mortgages or no mortgage who want financial security for their family (e.g., to cover living costs, education, or other expenses)

  • People who prefer flexibility in how the payout can be used

Joint life insurance

Works in the same way as a single life insurance policy, but it can cover two people under the same policy. It is designed mostly for married couples, long-term partner, and business partners.


Income protection

Pays a regular monthly income to the business if the employee becomes ill and is unable to work

Whole of life insurance

Also known as life assurance, whole of life insurance a type of policy that ensures a payout throughout your entire life. As long as you keep up with your premiums, your family will receive a lump sum payout once you die.

Pre-existing medical life insurance

Life insurance with pre-existing medical conditions covers you if you have a medical condition when you apply for a policy. It works similarly to standard life insurance, but the cost and coverage will depend on your medical history.

Death in service benefit

A death in service benefit is a lump sum of money paid to the beneficiary of an employee who dies while still working for the company. It's a benefit offered by some employers as part of their employee benefits package.
