Life insurance is not a legal requirement when you take out a mortgage. But the question of whether you need it almost answers itself when you think it through properly.
If you die with an outstanding mortgage and no life insurance in place, one of two things happens. Either someone else in your household continues to make the payments, or the property has to be sold. For most people, neither of those outcomes is what they would choose for the people they leave behind.
This guide explains the types of life insurance available to mortgage holders, how to think about how much you need, and the factors that affect the decision.
What happens to a mortgage when someone dies?
A mortgage does not disappear when someone dies. It is a legal debt secured against the property. If the mortgage is in joint names, the surviving party typically becomes solely responsible for the full mortgage. If the mortgage is in a single name, the mortgage becomes part of the deceased's estate.
In either case, the mortgage will need to be serviced or the property sold. If there is no life insurance to cover the debt, the family's options may be limited.
Life insurance exists to make sure that the mortgage is paid off, or at least that the family has the financial resources to continue making the payments, if the person taking out the mortgage dies before it is repaid.
Types of life insurance for mortgage holders
Decreasing term life insurance
Decreasing term insurance is designed specifically to track the outstanding balance of a repayment mortgage. The sum assured decreases over time in line with the mortgage balance, so if you die in the early years the payout is high, and if you die near the end of the term the payout is lower.
Because the risk to the insurer decreases over time as the potential payout falls, decreasing term insurance is generally the most affordable type of mortgage protection. The trade-off is that the payout is tied to the mortgage and does not provide any additional financial buffer for your family.
Level term life insurance
Level term insurance pays a fixed lump sum on death, regardless of when within the policy term you die. This is more expensive than decreasing term insurance because the potential payout does not reduce over time.
The advantage is that the payout is not limited to the mortgage balance. The additional amount can be used by the family for other purposes: living costs, school fees, or simply providing a financial cushion.
Family income benefit
Rather than paying a lump sum on death, family income benefit pays a monthly or annual income for the remainder of the policy term. If you have young children and your concern is replacing your income rather than clearing a specific debt, this can be a more practical structure than a lump sum.
Family income benefit is often overlooked in conversations about mortgage protection but is one of the most useful and cost-effective products available, particularly for families at an earlier stage of the financial journey.
Life insurance vs life assurance: the difference
Life insurance is a term policy that pays out only if you die within the policy term. If you survive to the end of the term, the policy ends and there is no payout.
Life assurance is a whole-of-life product that is guaranteed to pay out eventually, because the policy runs for the rest of your life rather than a fixed term. It is significantly more expensive and is generally used for inheritance planning and estate purposes rather than mortgage protection.
For mortgage protection, a term policy is almost always the appropriate product.
How much cover do you need?
The most straightforward approach is to take out a policy that covers the outstanding mortgage balance. This ensures that if you die, the mortgage can be cleared and the property secured for your family.
Whether you need more than this depends on your circumstances. If your income would be missed by your family beyond just the mortgage payment, a higher level of cover may be appropriate. If you have other financial commitments, dependants, or savings that would be depleted in the event of your death, it is worth thinking about the full picture rather than just the mortgage figure.
Joint vs single policies
For couples with a joint mortgage, joint life insurance is a common option. A joint policy covers both lives but typically pays out on the first death only, after which the policy ends. This means that the surviving partner has no cover after the payout.
Two single policies are often a better option for couples, even though they cost slightly more in total. Each policy pays out independently, so both partners retain cover after one of them dies. For couples with dependants, this is often the more appropriate structure.
Self-employed and business owners
If you are self-employed or run your own business, life insurance deserves particular attention. You do not have an employer providing death-in-service benefits, and your family's financial position in the event of your death depends entirely on what you have put in place personally.
For business owners, there may also be business protection considerations beyond personal life insurance. There is more on this in our business protection section.
Frequently asked questions
Is life insurance compulsory for a mortgage?
No. Lenders cannot legally require you to take out life insurance with them as a condition of the mortgage, though they can suggest it. The decision is yours. Whether it is the right choice depends on your personal circumstances and what the financial consequences of your death would be for the people who depend on you.
What is the difference between decreasing and level term cover?
Decreasing term insurance reduces in value over time to track a repayment mortgage balance. Level term insurance pays a fixed amount regardless of when within the term you die. Decreasing term is cheaper, level term provides more flexibility.
Can I get life insurance if I have health conditions?
In many cases, yes. Some health conditions result in higher premiums or exclusions, in more serious cases cover may not be available from all providers. A specialist protection adviser can identify which insurers are most likely to offer terms in your circumstances and at the best available price.
What is the difference between life insurance and critical illness cover?
Life insurance pays out on death. Critical illness cover pays a lump sum on diagnosis of a specified serious condition, such as a heart attack, stroke or cancer. They are distinct products that serve different purposes, and many people choose to have both.
