Critical Illness Cover made simple

If you were diagnosed with something serious, like cancer or a heart attack, critical illness cover can ease the money worries. So, you can focus on getting better, not bills. 

Critical illness cover pays a tax‑free lump sum if you’re diagnosed with a serious illness listed in your policy. The money is yours to use in the way that helps you most. Your health comes first. This cover gives you space to recover and adjust, without worrying about money. That could mean paying the bills, taking time off work, getting support, or making changes at home.

What is critical illness cover? 

Critical illness cover pays out a lump sum if you’re diagnosed with a serious illness or condition covered by your policy, such as cancer, a heart attack or a stroke. 

The money is paid to you and can be used however you choose. Many people use it to cover bills, rent or mortgage payments, childcare, medical costs, or time off work. 

Unlike life insurance, which pays out when you die, critical illness cover pays out while you’re still alive, usually after a short waiting period set by the insurer.

What does critical illness cover help with? 

It’s not just about the illness. It’s about what happens next. 

A serious illness can affect every part of your life - your income, your routine and your plans. Critical illness cover gives you time and flexibility when you need it most. 

A payout can help you: 

• pay for everyday things like food, bills and travel 

• replace income if you need time off work 

• pay for treatment, care or extra support 

• reduce money stress while you recover. 

It’s about having choices, not being forced into tough decisions at a hard time.  

Do I need critical illness cover? 

A serious illness can turn life upside down. But money worries don’t have to add to it. 

You may want to consider critical illness cover if your household depends on your income, you don’t have savings to cover a long-time off work or you want financial independence if things change suddenly. Even a small amount of cover can make a real difference. 

Critical illness cover could pay a lump sum. If you want regular income while you’re off work, income protection insurance may also be worth looking at. Many people choose to have both.

A quick reality check 

Critical illness cover is often misunderstood. 

Whether you’ve got a family, a mortgage, or you’re self-employed - if getting critically ill would hit your finances hard, this cover could make all the difference. 

These are the things we hear most: 

“It only pays if I can’t work” 
Not true. It could pay a lump sum based on diagnosis and policy wording. Not whether you stop working. 

“It’s only for people with mortgages” 
Many people use the money to cover living costs, income gaps and support their recovery. 

“I’ll deal with it if it ever happens” 
Cover is usually cheaper and easier to get while you’re healthy. Having it in place gives you options later. 

How does critical illness cover work? 

1. You choose how much cover you want and how long it should last
2. You'll be asked to answer some health and lifestyle questions, including full details on your medical history. 
3. Your chosen insurer will offer you terms. If you agree, this is when your monthly payments, or premiums, will start.
4. If you’re diagnosed with a covered condition and meet the policy definitions, you can claim
5. A successful claim pays out a tax‑free lump sum. 

You can take critical illness cover on its own, or alongside life insurance.

What does a critical illness policy cover? 

Cover varies between insurers, but most policies include serious conditions such as cancer, heart attack, stroke, Multiple Sclerosis (MS), and Parkinson’s disease and similar conditions 

What matters most isn’t how long the list is, but how each illness is defined. Two policies may list the same condition but pay out at different stages. That’s why it’s important to understand the details, not just the headline list. 

Some policies also pay smaller amounts for less severe conditions. These don’t replace the main payout but can help earlier on. 

Most policies cover many more conditions – some over 100+. We’ll help you focus on what matters for you, rather than just big numbers. 

If a condition isn’t listed, or doesn’t meet the policy rules, it won’t be covered.

What isn’t covered by critical illness cover? 

Critical illness cover is for serious, long‑term conditions.  

Each insurer is different, but the conditions that are typically not covered are pre-existing conditions, most mental health conditions*, back pain or general wear and tear*. Plus, hereditary illnesses (e.g. muscular dystrophy, sickle cell disease, Huntington’s disease), a diagnosis of a terminal illness or if you die before the end of an insurer’s survival period. 

If a condition isn’t listed - or doesn’t meet the policy definition - it won’t be covered. Many insurers will also insist on having the illness verified by a UK doctor or specialist. 

*These types of conditions can be covered and represent most common causes for claims under income protection insurance.

What’s the difference between ‘core’ and ‘enhanced’ critical illness cover? 

Some insurers offer a core version of cover, with more enhanced options available. 

Enhanced cover may include broader cancer cover, more conditions, extra payments for less severe illnesses and better children’s cover 

Core cover is often cheaper. Enhanced cover offers more depth and protection. The right choice depends on your needs and budget. 

How much critical illness cover do I need?

At a basic level, a small amount of critical illness insurance is better than nothing if you’re worried about developing a serious illness at some point in the future, and the financial consequences that could arise from this. 

A simple rule of thumb 

There’s no single right answer, but a common rule of thumb is around three years’ net income (what you take home after tax). This can help cover lost earnings, household costs and recovery time without immediate financial pressure. 

Build it step by step 

Because you can’t predict what might happen or how long recovery could take, it’s normal to feel unsure. A good way to approach it is to work through these simple steps. 

1. Review your monthly expenses 

Start with the basics. Look at what you need to pay each month, such as rent or mortgage, utility bills, food and travel, childcare or school costs and any loans or credit repayments. This gives you a clear picture of what it costs to keep life running. 

2. Think about time off work 

Now imagine you couldn’t work for a while because of illness. Ask yourself: 

• How much of your income would you lose each month? 

• Would you get any sick pay, benefits or other support? 

• How long might you need help for - months, or longer? 

Multiply the likely drop in income by the number of months you’d want support for. 

3. Consider treatment and recovery costs 

Serious illness can bring extra costs, such as travel to appointments, private treatment or rehabilitation, help at home and changes to your living space, like handrails or ramps. You don’t need to be exact. Just allow for the fact that recovery often costs more than people expect. 

4. Look at what you already have 

Think about any savings, investments or other assets you could use if needed. These can help, but it’s important to make sure you’re not relying on money you’ll need later or wiping out your safety net completely. 

You don’t need to get this perfect. The aim is to choose a level of cover that gives you options and peace of mind, not one that feels overwhelming or unaffordable. 

If you want help working this through, we can talk it through with you - clearly, calmly, and at your pace.

Example: £80,000 life and critical illness cover (increasing)

Example: £50,000 life and critical illness cover (increasing) 

This shows how reducing the level of cover can make policies more affordable, while still providing meaningful financial support if something serious happens. 

Standalone critical illness cover focuses purely on illness rather than combining it with life insurance. The cost at lower cover levels can be similar, but the way the policy pays out and what it protects is different. 

Example: £50,000 critical illness cover only (increasing)

Important information: These examples are based on real quotes for a healthy non-smoker in an administrative role, with no pre-existing medical conditions, over a 25-year term. They are for illustration only, sourced from Iress, June 2026. Prices will vary depending on your personal circumstances, health and the policy you choose. 

Why these examples use increasing cover 

All of the examples shown are based on increasing (index-linked) cover. 

This means the level of cover rises over time, usually in line with inflation, to help keep up with increases in the cost of living. It is particularly relevant if your aim is to support your household over the long term, rather than just cover a fixed cost. Premiums typically increase each year as the cover increases. 

Increasing cover is one option, but it is not the only one. You can also choose level critical illness cover, where the payout stays the same throughout the policy term and premiums are usually fixed. Level cover is often used where you are protecting a fixed amount, such as a mortgage or a specific financial commitment. Increasing cover is more commonly chosen where the aim is to protect future living costs.

What these costs mean in practice 

What matters most is not just the price, but how the policy is set up. A higher level of cover may cost more each month, but it can give you more flexibility if you need time off work, help at home or financial breathing space during recovery. Even smaller amounts of cover can make a real difference, especially when combined with other protection such as income protection insurance.

Do I choose joint or single life critical illness cover? 

Couples may often choose joint cover because it can look simpler or cheaper. But it’s worth understanding how joint and single policies work in real life. 

Why some people choose two single policies instead of one joint policy: 

Joint policy usually pays out once and then ends: If one person makes a full claim, the policy normally stops. There would be no cover left if the other person became seriously ill later.  

With two single policies, each person keeps their own cover: If one person makes a claim, the other person’s policy can stay in place. Each person’s health is looked at separately: One person’s medical history won’t affect the other person’s cover in the future. 

Children’s cover may pay out more than once: Where children’s cover is included, it may be able to pay out under each parent’s policy. 

Joint cover can still be right for some people, especially if keeping costs down is the main priority. 
But two single policies can give longer‑lasting protection for both people, even if life changes. 

Can I include my children under my critical illness cover? 

It’s hard to think about, but serious illness can affect children too. Some of the most difficult claims we see involve children. When a child is unwell, the focus should be on caring for them, not worrying about money or work. 

Many critical illness policies include children’s cover, either as standard or as an option.  

If a child is diagnosed with a covered condition, the policy may pay a smaller tax-free lump sum to help with things like time off work to care for them, travel and accommodation for treatment and extra support during recovery. 

Cover details differ, especially for conditions present from birth, so it’s important to understand what’s included.

Can I combine critical illness cover with life insurance? 

Critical illness cover is often taken out alongside life insurance, either as two separate policies or combined into one. 

When they’re combined into a single policy, it’s sometimes called ‘accelerated critical illness cover’. 

How accelerated critical illness cover works 

With an accelerated policy: 

• If you’re diagnosed with a serious illness covered by the policy, the critical illness payout is made. 

• If you die before the end of the policy term, the life insurance payout is made instead. 

• There is usually only one payout, not both. 

This can be a simple and cost-effective way to combine protection, depending on your needs 

Why life cover matters with critical illness cover 

Most critical illness policies include a short survival period. This means the insurer will only pay out if you survive for a set number of days after diagnosis. 

If someone were to die before the survival period ends, a standalone critical illness policy may not pay out. 

By adding life insurance to your critical illness cover there can still be a payout if you die shortly after diagnosis. This means your family isn’t left without support because of a technical timing rule, and the policy protects against both serious illness and death during the term 

People sometimes choose to buy two separate policies, one life insurance and one critical illness insurance policy. This is a good way to get a bit more flexibility. For example, you may want a life insurance policy to cover your mortgage, should you pass away, but only want a small amount of critical illness insurance to supplement the family income for a number of months if you were to fall ill. 

There’s no single right answer. The best option depends on your budget, priorities and who you’re protecting. 

We can talk this through with you, so you understand the trade‑offs and choose what’s right for your situation. 

When will my critical illness cover payout?  

If you make a successful claim, the money is paid out as a single lump sum. 

How long it takes can vary between insurers, as claims need to be assessed and verified. It’s important to notify your insurer as soon as you receive a diagnosis so they can explain the process and likely timescales. 

Claims are the real test of any insurer. What matters isn’t just how many claims are paid, but why claims are declined and how clearly decisions are explained. 

If you need to claim, our dedicated Claims Team can support you and your loved ones through every step, at no extra cost. 

Support beyond the payout 

Critical illness cover isn’t only about a future claim. Many policies include health and wellbeing support, such as annual health checks and screenings, 24/7 GP or medical advice access, second medical opinions, and mental health and counselling support. 

These services are designed to support you before, during and after illness, not just at claim stage.
