Compare Critical Illness Insurance

What is critical illness cover?

Critical illness cover is an insurance policy that pays out a tax free lump sum if you are diagnosed with a serious medical condition listed in your policy, such as cancer, a heart attack or a stroke. The payout is designed to help you manage your mortgage or rent, everyday bills and extra costs like treatment, travel or home adaptations while you are still alive and focusing on recovery.

What does critical illness insurance cover?

Most UK policies cover major illnesses such as certain cancers, heart attacks, strokes, organ failure, multiple sclerosis, Parkinson’s disease, Alzheimer’s disease and serious head injuries, although each insurer has its own detailed definitions and some offer optional extras or child cover.

What is not covered by critical illness policies?

Critical illness insurance will not usually cover conditions that are not named in the policy, very early or mild stages of an illness, diagnoses outside the policy term or situations where you die shortly after diagnosis, and many insurers insist that the illness reaches a set level of severity before they will pay out.

How much does critical illness cover cost?

The cost of critical illness cover depends on your age, health, lifestyle, job, level of cover and policy length, with younger, healthier non smokers generally paying much lower monthly premiums than older applicants or those with medical issues or higher risk occupations.

Do I need critical illness cover?

You are more likely to need critical illness cover if you rely on your income to pay a mortgage or rent, support dependants or cover regular bills, and would struggle to cope financially on savings, statutory sick pay or limited employer sick pay if you became seriously ill.

Key Points: How does critical illness cover work in the UK?

• Critical illness insurance pays a one off, tax free lump sum if you are diagnosed with a serious illness that meets your policy definition.
• It is different from life insurance, which pays out when you die, and income protection, which replaces part of your income if you cannot work.
• Typical conditions covered include cancer, heart attack, stroke, organ failure, multiple sclerosis, Parkinson’s disease and Alzheimer’s disease.
• Policies will not cover every condition, very mild illnesses or diagnoses made outside the policy term, and they often have strict medical definitions.
• You can choose level cover to keep the payout fixed or decreasing cover to broadly track a repayment mortgage.
• The right level of cover depends on your mortgage or rent, debts, regular bills, treatment costs and how long you might need to recover.
• Pre existing medical conditions do not always stop you getting cover, but they usually make it more expensive and may be excluded.
• State benefits and statutory sick pay are limited, so critical illness cover can provide an important financial cushion for many UK households.

Get Started

What is critical illness cover?

If you are diagnosed with a critical illness or suffer a serious injury, you might need time off work for treatment and recovery, which can put a real strain on your finances. Critical illness cover is designed to ease that pressure by paying a one off, tax free lump sum when you are diagnosed with a condition that is listed in your policy. You are free to use this money however you choose, but most people put it towards their mortgage or rent, everyday living costs, private treatment, paying off debts or adapting their home to make life easier while they get better.

Although it is often bought alongside life insurance, critical illness cover is about supporting you financially while you are still alive rather than paying money to your family after you die. It also works differently from income protection, which pays an ongoing monthly benefit instead of a lump sum. Understanding how these products fit together can help you choose the most cost effective mix of protection for your situation and avoid paying for cover you might not need.

Many low cost policies in the UK follow minimum standards set by the Association of British Insurers, which helps ensure that core conditions such as cancer, heart attack and stroke are covered on a broadly similar basis. However, the detail still varies a lot between insurers, so it is vital to read the small print carefully or use a specialist broker to compare policies side by side. This is especially important if you already have a health condition or want cover for particular illnesses that run in your family.

Critical illness cover vs life insurance

Critical illness cover and life insurance both exist to give you and your loved ones some financial security when things go wrong, but they are triggered by different events. Critical illness cover pays out if you are diagnosed with a serious illness or suffer a covered condition, such as a heart attack or stroke, that meets the policy’s medical definition. The idea is that you receive the money while you are alive and can use it to maintain your lifestyle, clear debts or pay for treatment.

Life insurance, by contrast, pays out when you die during the policy term. The payout usually goes to your partner, children or another person you have named as a beneficiary, and is intended to replace your income or help them cover major costs, such as a mortgage, childcare or everyday bills. Some life insurance policies have terminal illness benefit built in, which can pay the life cover early if you are diagnosed with a condition that is expected to be fatal within 12 months, but this is still different from full critical illness cover.

For many UK households, a combination of both types of cover works best. Life insurance can be a relatively cheap way to make sure your family can stay in the home and keep paying the bills if you are no longer around, while critical illness cover can provide extra protection against the financial shock of becoming seriously ill. If your budget is tight, you might choose to prioritise life insurance first, because death is a certainty, and then add a level of critical illness cover that fits around your mortgage and other commitments.

Income protection or critical illness cover?

Income protection insurance and critical illness cover are often compared because they both step in when your health affects your ability to earn, but they do so in different ways. Income protection pays you a regular, taxable income if you cannot work because of illness or injury, usually until you return to work, the policy ends or you reach a maximum claim period. It often covers a wide range of conditions, not just “critical” ones, and is designed to replace a percentage of your salary so you can carry on meeting regular expenses.

Critical illness insurance, by contrast, focuses on a list of specific, serious illnesses and injuries and pays a lump sum rather than an ongoing income. This money can be used in more flexible ways, for example to clear your mortgage, pay for private treatment, cover travel to hospital, fund a career change or build up a savings cushion so you can reduce your hours. Think of income protection as short or long term income replacement, and critical illness cover as a financial buffer for the big, life changing diagnoses.

If your main worry is how you would pay the day to day bills if you were too ill to work, especially if you have dependants and little in the way of savings, income protection may be the stronger starting point. If you are more concerned about the impact of a major diagnosis on your long term plans and want the option of a larger, one off payout, critical illness cover might suit you better. Ideally, you would have both, but if your budget will not stretch that far, it is worth talking to a broker or adviser about which combination gives you the most realistic protection for the money you are able to spend.

Critical illness cover vs terminal illness insurance

Critical illness cover and terminal illness insurance are sometimes confused, especially when life insurance policies include terminal illness benefit. Critical illness cover pays out if you develop one of the serious conditions named in your policy, such as certain types of cancer or a disabling stroke, and you are expected to survive. The payout is there to help you cope with the financial impact of living with and recovering from that illness.

Terminal illness insurance usually forms part of a life policy rather than being sold on its own. It pays out the life cover early if a medical professional confirms that your condition is expected to be fatal, often within 12 months, though the exact time frame varies between insurers. This early payment can give you and your family time to get your finances in order, clear debts, make practical arrangements and possibly pay for care or support that improves your quality of life in the time you have left.

Because the two types of cover are triggered by different circumstances, they are not interchangeable. It is possible to hold a life insurance policy with terminal illness benefit only, a standalone critical illness policy, or a combined life and critical illness plan. When comparing quotes, make sure you understand exactly what is included and when it would pay out, rather than assuming that one automatically covers the other.

What illnesses are covered by critical illness insurance?

The precise list of illnesses and injuries covered by critical illness insurance varies by provider, but most UK policies follow minimum standards that require them to cover at least cancer, heart attack and stroke at a defined level of seriousness. Many insurers also include other major conditions such as organ failure requiring transplant, multiple sclerosis, Alzheimer’s disease, Parkinson’s disease and traumatic head injury. In some cases, you may find cover for loss of limbs, loss of speech, loss of independent living or total and permanent disability, though definitions can be strict.

Some insurers go beyond the core conditions and offer “enhanced” or “comprehensive” critical illness policies that cover a wider list of illnesses, early stage cancers or less severe heart conditions. You might also have the option to add extra conditions for an additional premium, or to include children’s critical illness cover within your own policy, which can provide a smaller lump sum if your child is diagnosed with a serious illness.

When you are comparing policies, do not just look at the number of conditions listed in the marketing material. A shorter list with more generous definitions can sometimes be more valuable than a very long list with tight wording. Look closely at how the policy defines each condition, any survival periods you must meet after diagnosis and any exclusions or limitations, particularly if you want to be covered for a condition that runs in your family.

What is not covered by critical illness insurance?

Critical illness cover is not designed to cover every possible health problem. First, policies only pay out for the specific illnesses and procedures that are listed in your documents, and usually only if they reach a defined level of severity. For example, early stage cancers and less serious heart conditions may be excluded, or only covered under a lower “partial” payout if your policy offers this. Some conditions require you to have permanent symptoms in order to claim, which means milder or temporary issues may not qualify.

Second, there are timing limits. If you are diagnosed with a critical illness outside your policy term, you will not be able to claim. Many policies also exclude claims if you die within a set number of days after diagnosis, often known as a survival period. On top of that, any condition that is not explicitly named and defined in the policy will not usually be covered, unless your plan includes a separate total and permanent disability benefit that has its own definition.

Insurers commonly place exclusions around pre existing conditions, self inflicted injuries, drug or alcohol misuse and criminal activity. Many will insist that the illness is verified by a UK based consultant or specialist before they will pay a claim. This is why it is so important to read through the policy wording and key facts document before you buy, and to be completely honest on your application about your medical history, lifestyle and occupation.

How does critical illness insurance work?

You can buy critical illness cover in two main forms in the UK: as a standalone policy, or bundled with life insurance, often on a term basis that runs for a set number of years. When you apply, you choose how much cover you want – for example, £100,000 – and how long you want the policy to run, such as 25 or 30 years. If you are diagnosed with a covered condition during that term and meet all the policy definitions, the insurer pays the agreed lump sum and the cover ends.

There are two common ways to structure the amount of cover: level and decreasing. Level critical illness cover pays out the same fixed sum throughout the policy term, which can be useful if you want long term security for your family or to fund ongoing needs. Decreasing cover is usually set up alongside a repayment mortgage, so the potential payout reduces broadly in line with your outstanding loan. Because the insurer’s risk falls over time, decreasing policies are often cheaper than level ones for the same starting amount of cover.

When deciding how to set up your policy, it can be helpful to sit down and calculate how much money your household would realistically need if you could not work because of a serious illness. You might aim to clear your mortgage and any other debts, cover several years of household bills, allow for medical and rehabilitation costs and give yourself a cushion so you can recover without rushing back to work. Some policies also allow you to choose whether your sum assured increases each year in line with inflation, which can help your cover keep pace with rising living costs.

How much does critical illness cover cost?

The price you pay for critical illness cover is known as the premium, and it is usually collected monthly by direct debit. Insurers look at several key factors when calculating your premium, including your age, health, medical history, whether you smoke, your job, the amount of cover you want and how long the policy will run for. In general, the younger and healthier you are when you take out the policy, the cheaper your premiums will be, which is why many people arrange cover at the same time as taking on a mortgage.

To give you a flavour of how costs can vary, a healthy non smoker in an office based role in their early 30s will normally pay much less per £1,000 of cover than someone in their 50s or someone with a history of health issues. Higher sums assured and longer terms will increase the cost, while choosing decreasing cover rather than level cover can bring the price down because the payout reduces over time. Each insurer has its own pricing, underwriting rules and approach to risk, so it is always worth shopping around or using a whole of market broker.

Comparing like for like quotes can be tricky because some cheap policies have far more exclusions or stricter definitions. When you are looking for low cost insurance, focus not just on the monthly price, but on what you are getting for your money. Check the list of covered conditions, whether children’s cover is included, how the insurer treats partial payouts and whether they have a good track record of paying claims. Independent consumer sites and financial guidance services can be useful places to start your research.

How much critical illness cover do I need?

Working out how much critical illness cover you need is not an exact science, because every illness and family situation is different. However, a simple step by step approach can help you reach a sensible ballpark figure. Start by adding up your core monthly outgoings, including rent or mortgage payments, council tax, utilities, food, transport and other essentials. Also factor in any debt repayments, childcare costs and planned expenses such as school or university fees.

Next, think about how your income would change if you could not work. Check your employment contract or staff handbook to see how long your employer would pay sick pay and at what level, and then consider what would happen when that period ends. If you would need to rely on statutory sick pay or state benefits, there is likely to be a big gap between your usual income and what you would receive. Decide how many months or years of support you would want a lump sum to cover, and multiply your monthly shortfall by that number.

Then, consider one off costs linked to illness, such as rehabilitation, private treatment, travel to hospital, specialist equipment or making your home more accessible. Weigh these against any existing savings, investments or other assets that you could use without putting your long term plans at risk. Finally, remember that your circumstances and the cost of living will change over time, so it is wise to review your cover every few years, or when you have big life changes such as moving home, having children or changing jobs.

Can I get critical illness cover with pre existing medical conditions?

Having a pre existing medical condition does not automatically rule you out of getting critical illness cover, but it can make things more complicated. When you apply, the insurer will ask detailed questions about your health, medications, family history and any diagnoses or symptoms you have had in the past. It is essential that you answer these questions honestly and in full. If an insurer later discovers that you withheld information, they may refuse a claim or cancel the policy altogether.

Depending on the condition and its severity, an insurer might offer you cover with a higher premium, exclude claims relating to that particular illness, or in some cases decline to offer cover. For example, someone with well controlled high blood pressure might still get standard or slightly loaded rates, while someone who has recently had cancer may find that only a small number of specialist providers will consider them, and often with exclusions.

If you do have a medical history, it is often worth using a broker or adviser with experience in “impaired life” or specialist underwriting. They can help you present your case clearly to insurers and identify providers that are more flexible around certain conditions, which can save you time, stress and potentially money compared with applying blindly to multiple companies.

How to buy the right critical illness cover for you

Start by working out roughly how much cover you need and how long you want it to last, using your mortgage, debts and regular bills as a guide. Once you have a figure in mind, compare policies from a range of insurers, paying close attention not just to price but to the quality and scope of cover. Look at the list of illnesses, the wording of definitions, whether child cover is included, any partial payouts and whether the policy is standalone or combined with life insurance.

If you are comfortable doing your own research, you can get quotes directly from insurers or through price comparison sites. However, critical illness wording can be technical, and getting it wrong can be costly, so many people prefer to use an independent broker or regulated financial adviser. They can talk through your budget, priorities and existing benefits, then recommend a shortlist of policies that fit your needs, often with access to discounted premiums that are not available if you go to an insurer directly.

Before you sign up, read the key features document and full policy wording carefully, check any medical exclusions and make sure you are clear about how to claim if the worst happens. Keep your insurer or adviser updated if your circumstances change, and review your cover every few years so that it keeps pace with your life and your financial commitments.

When does critical illness insurance pay out and how long does it take?

Critical illness insurance pays out when you make a successful claim for a condition that is covered by your policy and meets the required level of severity. Once your insurer has received the medical evidence it needs, the payout is made as a single lump sum to your chosen bank account. Policies typically only pay out once, after which the cover ends, so it is important to think carefully about how you would use the money if you claim.

The time it takes to receive the money can vary. Straightforward claims, where the diagnosis is clear and all the paperwork is in order, may be paid within weeks, but more complex cases can take several months. Most policies include a minimum survival period, meaning you must live for a set number of days after diagnosis for the claim to be valid. If you are diagnosed with a serious illness, contact your insurer as soon as you can so they can explain the process, what evidence they will need and likely timescales.

Bundled critical illness and life cover

Many people choose a combined life and critical illness policy because it can be simpler and sometimes cheaper than arranging two separate plans. However, with a typical “bundled” policy there is usually only one pot of money. If you claim for a critical illness during the term, that payout will reduce or remove the amount that could later be paid to your family if you die. Buying separate life insurance and critical illness policies avoids this overlap but may cost more overall, so it is worth comparing both approaches.

Will my critical illness payout be taxed?

For most people in the UK, a payout from a critical illness policy is not treated as income, so you do not pay income tax on the lump sum. This makes it a very flexible way to access a significant amount of money at a difficult time, without worrying about a tax bill on top. However, there can be inheritance tax implications in certain situations, particularly where policies are arranged on a joint basis and the payout ends up forming part of a deceased person’s estate.

If a critical illness benefit is linked to a joint life insurance policy and the insured person dies before the payout is made, the money may be counted within their estate for inheritance tax purposes. If the total value of the estate is over the current inheritance tax threshold, tax could be due on some of the insurance payout. One way people sometimes plan around this is to write their policy “in trust”, which can keep the proceeds outside the estate and speed up payment to beneficiaries, although you should seek professional advice before doing so.

Do I need critical illness cover?

Not everyone will need critical illness cover, but it can be a useful safety net if you would struggle to pay the bills after a serious diagnosis. State benefits for sickness are limited, and while some employers offer generous sick pay, many only provide full pay for a short period or rely on statutory sick pay, which is much lower than the average wage and only lasts for up to 28 weeks. If you are self employed, on a zero hours contract or in a role with minimal benefits, the financial shock of being unable to work could be even greater.

Ask yourself how you and your family would cope financially if you could not work for a year or more because of a major illness. Would your savings and partner’s income be enough to cover the mortgage or rent, council tax, utilities, food, transport, childcare and other commitments, as well as any costs linked to your illness? If the answer is no, then critical illness cover is worth considering, particularly if you are the main earner or a joint breadwinner in your household.

For some people, building up an emergency fund and relying on employer benefits or income protection might feel sufficient, especially if they have no dependants or major financial commitments. For others, especially those with families and mortgages, a blend of life insurance, income protection and critical illness cover can provide more rounded protection. Taking time to review your current benefits, savings and risks will help you decide where critical illness cover fits into your overall financial plan.

Can you buy critical illness cover without life insurance?

Yes, you can buy standalone critical illness cover without taking out life insurance at the same time. This can be useful if you already have life cover through your employer or an existing policy, but want extra protection specifically for serious illnesses. A standalone policy can also give you more flexibility to adjust or review each type of cover separately as your circumstances change, for example if you pay off your mortgage early or your dependants become financially independent.

Before choosing standalone critical illness cover, think about your wider protection needs. If you do not currently have any life insurance, consider whether your family would be financially secure if you died unexpectedly. In many cases, arranging both types of cover at once can be cost effective, particularly if you opt for a combined policy, although it is important to understand how claims would work if you became ill and later died during the term. Taking independent advice can help you strike the right balance between cost and cover.

Next steps

If you think critical illness cover might be right for you, your next step is to review your budget, check what support you already have through your employer and the state, and decide how much protection you would like. You can then compare quotes from several insurers online, or speak to an independent adviser or broker who can do the legwork for you and explain the pros and cons of different options. Taking a little time now to put the right cover in place could make a huge difference to your financial security if you ever face a serious illness in future.
