Life insurance vs critical illness: which should I get first?

In an ideal world, you would have both. Life insurance to protect your family if you die. Critical illness cover to protect your finances if you are diagnosed with a serious condition. Income protection to cover you if illness or injury stops you from working for an extended period.

In the real world, money is finite, particularly when you have just bought your first home and every pound is accounted for. If you can only afford one product right now, which should it be?

The honest answer is that it depends on your circumstances. But there is a framework for thinking through it, and this article sets it out clearly.

What each product actually does

Before comparing them, it helps to be precise about what you are actually choosing between.

Life insurance pays a lump sum to your beneficiaries if you die during the policy term. Its primary purpose is to protect the people who depend on you (your partner, your children) from the financial consequences of losing your income and potentially losing the home.

Critical illness cover pays a lump sum to you if you are diagnosed with a serious covered condition during the policy term. Cancer, heart attack, stroke, and other significant illnesses are typical triggers. The money is yours to use as you choose: to repay the mortgage, to cover living costs during treatment, or to adapt to a changed situation.

These products address different risks. Life insurance addresses the risk of death. Critical illness cover addresses the risk of survival with a serious illness and the financial disruption that follows.

The case for prioritising life insurance

Life insurance is typically the more straightforward starting point, for a few reasons.

It addresses one of the most financially catastrophic scenarios. If you die and your mortgage is not covered, your family may lose their home. The impact is immediate, irreversible, and falls on the people least equipped to deal with it at that moment.

It is usually cheaper per pound of cover than critical illness. A decreasing term policy that covers your mortgage balance costs less, in most cases, than a critical illness policy providing the same sum assured. This means you can secure meaningful protection for a lower monthly outlay.

It is simplest to structure. A decreasing term policy matched to your mortgage balance and term provides a clear and uncomplicated level of coverage. There is less to decide, and the product does exactly what most buyers need it to do.

For buyers with dependants (a partner, children, or others who rely on their income), life insurance is generally the more direct solution to the most pressing risk.

The case for prioritising critical illness cover

The statistical argument for critical illness cover is compelling and often overlooked.

You are considerably more likely to be diagnosed with a serious illness during your working lifetime than to die during it. A healthy person in their thirties has a low probability of dying before they reach sixty or sixty-five. The same person has a significantly higher probability of receiving a serious illness diagnosis: cancer alone affects roughly one in two people in the UK at some point in their lives.

Life insurance does not help you in that scenario. It pays on death. If you survive a heart attack or complete cancer treatment but face months of reduced income, significant medical costs, or the need to adapt your home and lifestyle, a life insurance policy sitting quietly in the background does nothing for you.

Critical illness cover addresses precisely this gap. For buyers without dependants (those buying alone, or in a couple where both partners earn well), the financial risk of a serious illness diagnosis is arguably greater than the financial risk of death. Critical illness cover can be the more targeted protection for that scenario.

How to decide

Rather than applying a universal rule, ask yourself these questions honestly.

Do I have dependants who rely on my income? If you have a partner who does not work, or children, or anyone else whose financial wellbeing depends on your earnings, life insurance is generally the priority. Their financial security in the event of your death is one of the most urgent risks to address.

Does my partner have an income that would cover the mortgage if I died? If both of you earn enough that the survivor could manage the mortgage alone, the urgency of life insurance is reduced. In this situation, the risk of a serious illness diagnosis that disrupts your own finances may be the more pressing concern.

Do I have savings that would cover me for several months if I could not work? If you have a meaningful financial cushion, you have some natural resilience against short-term income disruption. This changes the calculus slightly in favour of life insurance first, because the immediate catastrophic scenario of death remains unaddressed by savings in a way that a period of illness might not be.

Is one of you self-employed? Self-employed buyers have no employer sick pay. A serious illness means income stops immediately. For self-employed buyers, the financial risk of illness is arguably more acute than for employed workers with generous sick pay, and this points toward prioritising critical illness cover or income protection.

What if you can afford both?

If your budget allows for both life insurance and critical illness cover, both are worth having. They complement each other and address different risks. A combined life and critical illness policy is one option (it typically costs less than two separate policies), though the trade-off is that it pays out once and then ends.

Two separate policies provide better ongoing protection: life insurance that continues after a critical illness payout, and critical illness cover that continues even if a life insurance claim is not made. An adviser can model both structures and show you the cost difference.

Income protection: the often-forgotten third option

Any discussion of protection priorities is incomplete without mentioning income protection, because it covers the scenario both life insurance and critical illness can miss.

You are most likely to be off work not because of a dramatic diagnosis from the critical illness list, but because of depression, back problems, stress, or any number of conditions that are serious enough to prevent you from working but that may not trigger a critical illness payout.

Income protection covers any reason you cannot work (no specific diagnosis required) and pays a monthly income for as long as the incapacity continues. For many buyers, particularly those who are self employed or who have limited employer sick pay, income protection is often the most practically useful protection product to consider.

If your budget allows only one product, and you have no dependants, a strong case can be made for income protection over either life insurance or critical illness cover, because it addresses the most statistically likely disruption to your financial life.

An adviser can look at your specific income, your mortgage, your employer benefits, and your family situation and help you decide where the protection spend makes the most difference.
