Life Insurance vs Critical Illness Cover: What’s the Difference?

Life insurance and critical illness cover are both designed to provide financial protection, but they respond to very different events. 

Life insurance is generally designed to provide a financial benefit if the insured person dies during the policy term, subject to the policy conditions. 

Critical illness cover is generally designed to provide a benefit while the insured person is still alive, following diagnosis of a specified serious illness that meets the definition contained within the policy. 

The distinction is important because the financial consequences can be very different. 

If you die, the concern may be how your household continues without your income and whether significant liabilities, such as a mortgage, can still be managed. 

If you survive a serious illness, the challenge may instead be reduced earnings, additional expenditure and the need for greater financial flexibility while regular commitments continue. 

For that reason, the question is not always whether to choose life insurance or critical illness cover. Depending on your circumstances, both risks may warrant consideration.

Income Protection vs Critical Illness Cover At A Glance

Income protection Critical illness cover
Primary purpose Help replace lost earnings Provide capital following a qualifying diagnosis
Typical benefit Regular payments Lump-sum benefit
Claim trigger Qualifying inability to work due to illness or injury Diagnosis of a specified condition meeting the policy definition
When payments begin Usually after an agreed deferred period Following an eligible diagnosis and successful claim
Mortgage role Can help maintain regular mortgage payments Lump sum could potentially reduce or repay mortgage borrowing
Main risk addressed Loss of earnings Financial impact of specified serious illness
Can you have both? Yes Yes

The precise cover, exclusions, definitions and claim conditions depend on the individual policy. 

What Is The Main Difference Between Life Insurance and Critical Illness Cover?

The main difference is the event that normally triggers a claim. 

With life insurance, a benefit is generally payable following the death of the insured person during the policy term, provided the claim meets the policy conditions. 

With critical illness cover, the insured person remains alive. A benefit may become payable following diagnosis of a specified serious medical condition, provided the diagnosis meets the insurer’s definition. 

The two policies therefore address different financial questions. 

What would happen to your household financially if you died? 

And: 

What would happen financially if you survived a serious illness but your income, expenditure or wider circumstances changed significantly? 

The answer to each can be very different, which is why one form of protection should not automatically be viewed as a substitute for the other. 

When Does Life Insurance Pay?

Life insurance is generally designed to provide a financial benefit following the death of an insured person during the policy term, subject to the policy conditions. 

Depending on how the policy is arranged, the benefit could potentially help those left behind to: 

  • repay or reduce a mortgage; 
  • meet household expenditure; 
  • manage other debts or financial commitments; 
  • support children or other dependants; or 
  • reduce the financial impact of losing an income. 

The appropriate amount and structure of cover therefore depend on what you want the policy to achieve. 

For one household, the principal objective may be repaying the mortgage. 

For another, the requirement may extend beyond the mortgage to replacing lost income or providing additional financial support for a family over a longer period. 

The mortgage balance may be an important reference point, but it should not necessarily be the only one. 

When Does Critical Illness Cover Pay?

Critical illness cover generally provides a benefit following diagnosis of a specified serious medical condition, provided the diagnosis meets the definition contained within the policy. 

The policy definition matters. 

Being diagnosed with a condition that has the same general name as one listed by the insurer does not automatically mean a benefit will be paid. The diagnosis must meet the specific criteria set out within the policy. 

Following a successful claim, the benefit could potentially be used to: 

  • repay or reduce mortgage borrowing; 
  • reduce other financial commitments; 
  • meet household expenditure; 
  • adapt your home; 
  • meet additional costs arising from your circumstances; or 
  • provide greater financial flexibility during treatment and recovery. 

Unlike life insurance, the benefit is intended to provide financial support while you remain alive following a qualifying diagnosis. 

Can Life Insurance and Critical Illness Cover Both Protect Your Mortgage?

Yes, but they protect against different events. 

Life insurance can provide capital following death that could potentially be used to reduce or repay an outstanding mortgage. 

Critical illness cover can also be arranged with the mortgage in mind, but the benefit may become payable while you are alive following a qualifying diagnosis. 

Consider a household where the mortgage depends heavily on one person’s earnings. 

If that person dies, the remaining household may need capital to reduce borrowing and compensate for the permanent loss of an income. 

If that person survives a serious illness, the position can be different. Income may fall, additional costs may arise and mortgage payments can continue throughout treatment or recovery. 

Protecting against one scenario does not automatically provide protection against the other. 

Can You Have Life Insurance and Critical Illness Cover Together?

Yes. 

Because life insurance and critical illness cover address different financial risks, there may be circumstances where considering both is appropriate. 

They can potentially be arranged through separate policies or through arrangements where life and critical illness protection are connected. 

How the cover is structured matters. 

Depending on the policy, a successful critical illness claim may affect or end an associated life insurance benefit. Other policies may operate differently. 

When considering combined or separate cover, relevant factors can include: 

  • the amount of protection required; 
  • how each benefit operates; 
  • policy definitions; 
  • exclusions and limitations; 
  • the policy term; 
  • existing protection; 
  • affordability; and 
  • what happens to any remaining cover following a claim. 

The purpose should not simply be to hold both types of insurance. Each should address a clearly identified financial risk. 

Which Is Better: Life Insurance or Critical Illness Cover?

Neither is universally better because they are designed to respond to different events. 

Life insurance may be particularly relevant where other people would face financial difficulty following your death. 

Critical illness cover may be relevant where surviving a serious illness could create a significant financial requirement while you are still alive. 

A useful way to compare them is to consider both scenarios separately. 

If you died 

Would your household be able to: 

  • maintain or repay the mortgage; 
  • replace the income you previously provided; 
  • meet everyday expenditure; 
  • support children or other dependants; and 
  • manage other borrowing and financial commitments? 

If you survived a serious illness 

Would you be able to: 

  • continue meeting mortgage payments; 
  • absorb a reduction in earnings; 
  • meet additional expenditure; 
  • avoid drawing heavily on savings or investments; and 
  • maintain greater financial flexibility during treatment or recovery? 

If one scenario would create considerably more financial pressure than the other, that may influence which protection deserves greater priority. 

If both would create a meaningful shortfall, there may be a case for considering both. 

How Much Life Insurance and Critical Illness Cover Might You Need?

There is no standard amount that is appropriate for every household. 

The level of cover should reflect both your circumstances and what you want each policy to achieve. 

For life insurance, relevant considerations can include: 

  • outstanding mortgage borrowing; 
  • other debts; 
  • household expenditure; 
  • loss of future income; 
  • children and other financial dependants; 
  • savings and investments; 
  • existing life insurance; and 
  • employer-provided death benefits. 

For critical illness cover, you may also want to consider: 

  • whether you would want to reduce or repay the mortgage; 
  • the potential financial effect of time away from work; 
  • employer sick pay; 
  • accessible savings and investments; 
  • existing critical illness cover; 
  • potential additional expenditure; and 
  • how much financial flexibility you would want following a serious diagnosis. 

Automatically matching both policies to the mortgage balance can overlook other financial requirements. 

Equally, arranging the maximum level of cover available is not necessarily the most appropriate approach. 

The objective is to understand the financial consequences your household would find difficult to absorb and consider an appropriate and sustainable level of protection. 

What Happens If You Survive A Serious Illness?

This is one of the clearest distinctions between life insurance and critical illness cover. 

If you survive a serious illness, life insurance alone would not ordinarily provide the same financial support because the insured person remains alive. 

However, your financial circumstances may still change considerably. 

You may need time away from work, experience a reduction in earnings or face additional expenditure while mortgage payments and other commitments continue. 

Critical illness cover is designed to address this different risk by potentially providing a lump-sum benefit following a qualifying diagnosis. 

There can, however, be another gap. 

An illness or injury could prevent you from working for an extended period without meeting the requirements for a critical illness claim. 

That is where income protection addresses a different financial exposure. 

Where Does Income Protection Fit?

Life insurance, critical illness cover and income protection each address a different primary risk. 

Life insurance can provide financial support following death, subject to the policy terms. 

Critical illness cover can provide a lump sum following a qualifying serious diagnosis. 

Income protection can provide regular replacement income following a qualifying inability to work because of illness or injury. 

For example, you could be unable to work for a prolonged period because of a condition that does not result in a critical illness benefit. 

Income protection may address that loss-of-earnings risk, subject to the policy conditions. 

This does not mean everyone requires all three forms of protection. 

The more useful approach is to assess each risk against the resources already available through savings, household income, existing insurance and workplace benefits. 

Life Insurance and Critical Illness Cover For Your Mortgage

A mortgage is often one of the main financial commitments that leads people to consider personal protection. 

However, the financial risk is rarely limited to the mortgage balance alone. 

If you died, your household may need to replace lost income as well as deal with the outstanding borrowing. 

If you survived a serious illness, repaying the mortgage might not necessarily be the only priority. Maintaining accessible capital for everyday expenditure or additional costs could also be important. 

Protection planning should therefore consider the mortgage within the wider financial picture. 

Relevant factors may include: 

  • household income; 
  • regular expenditure; 
  • dependants; 
  • savings and investments; 
  • workplace benefits; 
  • existing protection; and 
  • other liabilities or financial commitments. 

This provides a more meaningful basis for deciding how much cover may be appropriate and what each policy should be intended to achieve. 

Life Insurance and Critical Illness Cover For Self-Employed Professionals

For self-employed professionals and business owners, both risks can require additional consideration. 

There may be no employer-funded death-in-service benefit, contractual sick pay or other workplace protection to rely on. 

Income may also depend directly on the individual’s ability to continue practising or running a business. 

If that person dies, the financial effect may extend beyond the loss of personal income. 

If they survive a serious illness, there may be both a reduction in earnings and an immediate need for additional financial flexibility. 

Relevant considerations can include: 

  • how income is generated; 
  • the consistency and structure of earnings; 
  • mortgage and other liabilities; 
  • accessible savings; 
  • business continuity arrangements; 
  • family commitments; 
  • existing insurance; and 
  • other household income. 

Understanding the wider financial position can therefore be particularly important before deciding whether life insurance, critical illness cover or both are appropriate. 

When Should You Review Your Cover?

Life insurance and critical illness requirements can change substantially over time. 

A review may be appropriate when you: 

  • buy or move home; 
  • remortgage or increase your borrowing; 
  • get married or enter a long-term partnership; 
  • have children; 
  • become self-employed; 
  • establish or sell a business; 
  • change employer or occupation; 
  • experience a significant change in income; 
  • take on additional financial commitments; or 
  • experience another material change in your circumstances. 

Existing protection should form part of that review. 

An older policy should not automatically be cancelled or replaced. Its existing benefits, definitions and terms may remain valuable, while changes to your age, health or circumstances can affect the cost or availability of replacement cover. 

Where new protection is being arranged, existing cover should not normally be cancelled until the replacement policy has been confirmed and is in force. 

Choosing Life Insurance, Critical Illness Cover Or Both

Rather than starting with the products, begin with the financial risks. 

Consider: 

  1. Who depends financially on you? 
  1. What would happen to your mortgage if you died? 
  1. How would your household replace the income you currently provide? 
  1. What would happen financially if you survived a serious illness? 
  1. What savings, investments and workplace benefits are already available? 
  1. What insurance do you already have? 
  1. Which risks would be most difficult for your household to absorb? 

The answers can help establish whether life insurance, critical illness cover or a combination of the two deserves consideration. 

Taking A Joined-Up Approach To Protection

Life insurance and critical illness cover protect against different events, but both sit within the same broader question: how financially resilient would you and your household be if circumstances changed unexpectedly? 

At Henry Dannell, we believe protection is best considered within that wider financial context. 

That can include your mortgage, income, employment or self-employment arrangements, existing insurance, workplace benefits, savings, dependants and other financial commitments. 

For professionals, business owners and self-employed clients, additional consideration may be required because income can be more complex and conventional employee benefits may be limited or unavailable. 

The objective is not to arrange the greatest possible amount of insurance. 

It is to understand the risks that matter, identify the resources and protection already available and determine whether additional cover could address any remaining financial gaps appropriately. 

A protection review can help bring those elements together and establish whether life insurance, critical illness cover or a combination of different forms of protection may be appropriate for your circumstances.

A mortgage is secured against your property. Your property may be repossessed if you do not keep up repayments on your mortgage or any other debt secured against it.

Insurance policies are subject to eligibility, underwriting, exclusions, limitations and policy terms. Critical illness and income protection definitions, and the circumstances in which benefits are payable, vary between policies and insurers.
