What Is Critical Illness Cover? And Do You Need It?

The Problem Life Insurance Does Not Solve

Life insurance pays out when you die. But what if you survive a serious illness — a heart attack, stroke, or cancer diagnosis — and are left unable to work for months or years? Your mortgage still needs to be paid. Your family still needs to eat. Medical bills may be mounting.

This is exactly the gap that critical illness cover is designed to fill. It pays a tax-free lump sum if you are diagnosed with one of a specified list of serious conditions — whether you die or not.

What Does Critical Illness Cover Pay Out For?

Every insurer's list differs, but most critical illness policies cover a core set of conditions. The most commonly covered include:

• Cancer — usually of a specified severity; early-stage cancers may be covered at a reduced rate
• Heart attack — of a specified severity
• Stroke — resulting in permanent symptoms
• Coronary artery bypass surgery
• Multiple sclerosis
• Total permanent disability
• Major organ transplant
• Kidney failure
• Blindness, deafness, or loss of limbs

Some policies cover 30–50 conditions, while premium policies may cover over 100. More conditions is generally better, but read the definitions carefully — how each condition is defined can matter as much as whether it is listed.

How Much Does Critical Illness Cover Pay?

You choose the payout amount when you buy the policy — typically between £50,000 and £500,000 (or equivalent). Unlike income protection, it pays a lump sum, not a monthly amount. You use the money however you need to — pay off your mortgage, fund private medical treatment, adapt your home, or simply maintain your family's living standards while you recover.

How Much Does It Cost?

Critical illness cover is more expensive than term life insurance alone because the probability of a serious illness diagnosis during your working life is significantly higher than the probability of death. Rough benchmarks for a healthy non-smoker:

Age	Coverage	Term	Approx Monthly Cost
30	£200,000 / $250,000	20 years	£30–£50 / $38–$65
40	£200,000 / $250,000	20 years	£70–£110 / $90–$145
50	£200,000 / $250,000	15 years	£150–£250 / $195–$325

Critical Illness + Life Insurance: Combined Policies

Many insurers offer combined life and critical illness policies. These typically come in two forms:

• Joint life and critical illness: Pays out on whichever happens first — diagnosis of a critical illness OR death. After a payout, the policy ends. Often cheaper than buying both separately.
• Separate policies: Pays out independently for critical illness and for death. More expensive but provides the most complete protection.

Do You Need Critical Illness Cover?

Ask yourself these questions:

• Could your family maintain their mortgage payments if your income stopped for 6–24 months?
• Do you have enough savings to cover living expenses and potential medical costs during a serious illness?
• Would your employer continue to pay your salary if you were seriously ill for over 6 months?

If the answer to any of these is no, critical illness cover is worth serious consideration. Statistically, you are significantly more likely to be diagnosed with a serious illness during your working life than to die — making it arguably a higher priority than life insurance alone for people without dependants.
