The difference between life insurance and mortgage life insurance

We all want to ensure our loved ones are financially protected. But that doesn't mean everyone wants protection for the same reasons. So it makes sense that there's different types of insurance to choose from. This article considers mortgage protection insurance, life insurance and mortgage life insurance.

Mortgage protection insurance’ can refer to different things. For example:

  • Mortgage protection insurance is a type of Payment Protection Insurance (PPI). It insures monthly mortgage costs if the policy holder is temporarily unable to work. You can insure against accident, sickness or unemployment, depending on your priorities. The maximum payment period is between 12 and 24 months, but it could end sooner if you return to work. Legal & General does not offer this type of insurance. Speak to an adviser if you want to find our more. 
  • Mortgage life insurance. This type of ‘mortgage protection’ is a life insurance policy that’s designed to cover a repayment mortgage. Unlike Mortgage protection payment insurance, it pays out upon death rather than illness or injury, and only pays out once. Legal & General’s Decreasing Life Insurance is a type of mortgage life insurance.

What about life insurance vs mortgage life insurance?

How does mortgage life insurance differ from a standard life insurance policy? Both of these types of life insurance can be used for mortgage protection purposes, but that doesn’t tell the whole story. 

What do we mean by life insurance and decreasing life insurance? These are common terms used to describe different types of protection.


What is life insurance?

Life insurance is usually a policy that provides level cover if you die during the length of the policy. In other words, the amount of cover stays the same until the policy ends. If you’re no longer around, it can provide protection for a mortgage, and indeed any purpose, such as:

  • Helping loved ones pay the household bills
  • Supporting children through higher education
  • Paying the rent (not just mortgage protection).

Legal & General’s Life Insurance policy is an example of this type of insurance.


What is mortgage life insurance?

Mortgage life insurance normally describes a type of life insurance where the cover decreases over the length of the policy. It’s designed to protect a mortgage that reduces over time, so it’s often used to protect a repayment mortgage. For that reason it’s sometimes referred to as ‘mortgage life insurance’. Our Decreasing Life Insurance policy is an example of this type of insurance.

For the purpose of the rest of this article, when talking about 'mortgage life insurance' we are referring to 'decreasing mortgage life insurance'.

Just remember that life insurance is not a savings or investment product and has no cash value unless a valid claim is made.

Okay, so what different types of life insurance are there? We have a range of products you can buy directly from Legal & General. The first that many people choose to purchase, especially when they're trying to cover their mortgage, is decreasing life insurance. And what it's designed to do is decrease at the same rate that your mortgage decreases*.

Another product we also have at Legal & General is life insurance, also known as term insurance. And what that's designed to do is pay out a fixed amount of cover over a fixed term.

So, if you imagine you had a mortgage, which is decreasing, and you have an amount of cover which is level. As your mortgage decreases, that leaves you a surplus to go to your family and for them to spend as you wish. Another thing that term assurance often does is people use it to protect their family, often over a given period of time.

So, it might be when your children are born and you want to protect them until they're 21, for instance. So, you take out a policy for that period for an amount of cover that you decide that they will benefit from on your death. 

If you're looking for a life insurance product for seniors, we have an over 50s life insurance product which is designed to pay towards your funeral or leave a gift for your loved ones.

Whole of Life is a product available through financial advisors. And what that's designed to do is pay out on the inevitable that you die. So, there is no fixed term, just pay a premium until the day of death. And that money is designed to go to whoever you wish for them to spend however they wish.

*Decreasing Life Insurance is designed to help protect but is not directly linked to a repayment mortgage.

An illustration on the differences between life insurance and mortgage life insurance.

A fundamental difference between life insurance and mortgage life insurance is what happens to your cover amount during the length of the policy.

With a life insurance policy, your amount of cover will stay the same regardless of when a valid claim is made during the policy term.

In contrast, the potential payout from mortgage life insurance to cover a repayment mortgage reduces over time. So while you will have ‘mortgage protection’ that can lead to a payout following a valid claim, it will likely be a lower amount compared to a level term policy, if the original cover amount was the same.

Mortgage life insurance isn’t for everyone. For example, it might not be the right policy if you want financial protection that doesn’t lessen over time. However, taking out mortgage life insurance to protect a repayment mortgage can have its benefits:

  • It works for you. The policy can be tailored to your needs. You choose the amount of cover you need to match your mortgage amount and you choose the number of years you need the cover for. It can be taken in joint or single names. 
  • It’s easy to choose the cover amount. If you're only looking to protect a repayment mortgage, you know the protection you need for peace of mind.
  • It’s cheaper. Decreasing mortgage protection is often cheaper than other types of life insurance. We’ll explore the reasons for this next.

Yes, mortgage life insurance is typically cheaper than a life insurance policy. This is because the amount of cover decreases over time so the potential payout is less than life insurance, which is fixed. However, there are many factors that determine life insurance premiums – and whether you can get a policy at all – including your age, overall health, smoker status and alcohol consumption.

Life insurance isn’t just for homeowners. When deciding on what type of life insurance policy you may need, it could help to think about who and what you are trying to protect. If you have children, for example, you may have a wider set of outgoings to protect than just the mortgage. A level term life insurance policy can be a good choice for family and mortgage protection. 

However, a ‘decreasing’ life insurance policy for mortgage protection can be an affordable option if you have a repayment mortgage and you’re looking to keep costs down.

Some people have a combination of life insurance and decreasing life insurance. This can work if you want cover for a repayment mortgage and level cover for family protection. 

Could your loved ones manage financially without you?

Every household has different needs, but a good rule of thumb is that if someone else relies on your income – whether that’s a partner, children or another family member – you may want to consider life insurance of some kind. You should speak to your financial adviser if you need help choosing the best policy for your needs.

Regardless of what type of policy you chose, taking out a policy can help provide financial security to your loved ones should the worst happen.
