Critical Illness Insurance vs Income Protection​

You choose the level of cover

When you apply, you decide how much cover you want. This allows you to tailor the policy around your mortgage, debts, income, or family needs.

If your employer offers some form of sick pay, you can use the policy to complement this by covering any potential financial gaps that could arise from a serious health condition.

Only covers specific conditions

Not all conditions are covered. If your illness isn’t listed in the policy or doesn’t meet the insurer’s definition, the policy won’t pay out. For instance, not all cancers are covered at every stage, and some conditions must reach a certain level of severity before a claim is valid.

A lump sum to cover real-life costs

The payout can be used for anything from childcare and bills to everyday living expenses while you recover. Some people use it to reduce financial pressure by paying down large commitments like a mortgage.

Strict definitions apply

Even if a condition is listed, insurers assess claims carefully against their medical definitions. A heart attack or stroke must meet specific clinical criteria, which can sometimes lead to confusion or disappointment if a condition doesn’t qualify under the policy terms.

Covers serious, life-changing conditions

Most policies include major illnesses such as many types of cancer, heart attacks and strokes, along with other serious conditions defined in the policy wording.

Typically pays once and ends

In most cases, once a full claim has been made, the policy ends. This means you won’t be covered for future illnesses unless you take out a new policy. By then it may be more expensive or harder to obtain, depending on your health at that time.

Option to increase cover later

Some insurers may allow you to increase your cover after certain life events (like having a child or moving home) without further medical underwriting. It's always best to review your cover every so often to make sure it matches your current needs.

Doesn’t replace long-term income

While a lump sum can reduce financial pressure, it may not provide sustained income support if you’re unable to work for many years. This is where you may need additional protection alongside it, such as life insurance.

Can be added to life insurance

Critical illness cover is often combined with life insurance under one policy. Both can provide adequate protection, though they have some differences when used separately. See life insurance vs critical illness cover for more information.

Covers a wide range of conditions

Unlike critical illness cover, income protection doesn’t rely on a fixed list of serious illnesses. It can pay out for many physical and mental health conditions, such as stress, anxiety, depression, back problems and musculoskeletal injuries. This is providing they prevent you from doing your job under the policy definition.

No lump sum payout

Income protection won’t provide a large one-off payment to clear a mortgage or major debts. If you need immediate capital to reduce financial commitments, another type of cover may be more suitable.

Provides ongoing monthly income

Rather than a one-off payment, you receive regular monthly payments. This can make it easier to manage everyday living costs such as mortgage or rent payments, utilities, food and childcare.

The deferred period can delay payments

You must wait for your chosen deferred period before payments begin. It could create short-term financial pressure if you don’t have savings or sick pay to cover this gap.

Long-term support available

Some policies can continue paying until you return to work, reach retirement age, or the policy term ends. For long-term illnesses or disabilities, this can provide sustained financial stability.

Doesn’t replace your full salary

Policies usually cover up to 50–70% of your gross income. Because of this, you may need to budget carefully once you receive payments, as you won’t receive enough to cover your full earnings.

You could claim multiple times

If you do claim on the policy and then recover and return to work, you may be able to claim on the policy again for the same condition, or something new, providing that you’re still within the term of the policy and meet the terms set out by the insurer.

Payments stop when you return to work

Based on the policy’s incapacity definition, your payments will end once you’re medically fit to return to work. So, if your condition improves, even partly, it could affect ongoing claims.

Can be customised to your situation

One of the key benefits of income protection is that it's flexible and can be tailored to your circumstances. With it you can choose:

• The amount of cover (typically up to 50–70% of your income)

• The deferred period (how long before payments start)

• The policy term

This allows you to align cover with savings, employer sick pay or other financial arrangements.

Can be more expensive for higher-risk occupations

Your job, health, age and lifestyle can all influence the cost of your cover. For those in manual or high-risk occupations, it may result in higher premiums or exclusions.

Strong option for self-employed workers

If you’re self-employed and don’t have access to employer sick pay, income protection can be particularly valuable. It can act as your primary financial safety net should an illness or injury prevent you from earning.

More complex compared to simpler policies

Income protection policies are often more complex than policies like life insurance because they include specific terms around deferred periods, benefit levels, and what counts as being unable to work.

Some conditions may only trigger partial payments, certain jobs may be treated differently, and exclusions or waiting periods can affect when you start receiving benefits.

Policies can include additional features

Some insurers offer added benefits such as rehabilitation support, return-to-work assistance, or limited payments while you recover gradually.

One-off lump sum on diagnosis of a covered condition

Regular monthly payments while unable to work

Specific serious illnesses (e.g., cancer, heart attack, stroke)
