Critical illness
Is critical illness cover worth it?
The short answer
Critical illness cover is worth it when a serious illness would cost your household more than it could absorb — for example, with dependants, a mortgage, little sick pay or few savings. It is worth less if you already have generous sick pay, substantial savings or employer cover. Most claims are paid, but definitions decide.

Whether critical illness cover is worth it
Critical illness cover is worth it when the financial impact of a serious illness would be more than your household could absorb on its own. It is worth less when you already have generous sick pay, substantial savings, an employer policy or no one relying on your income. There is no universal answer, and anyone who gives you one without asking about your finances is guessing.
What we can do is set out, using official and industry figures, what the cover pays for, how often claims are paid, which situations make it more or less valuable, and the questions that help you decide. The Health Guide does not give advice or recommend products; if you want a personal recommendation, speak to an FCA-authorised adviser.
Insurers paid £7.84 billion in protection claims across life, critical illness and income protection in 2025, according to the Association of British Insurers, [1] following a record £8 billion in 2024. [2] Those totals show that claims are paid at scale — but they cannot tell you whether a policy is right for your circumstances.
What you are actually buying
Critical illness cover pays a single tax-free lump sum if you are diagnosed with one of the conditions listed in your policy and the diagnosis meets the written definition. The core conditions on most policies are specified cancers, heart attack and stroke, and many policies list dozens more, sometimes with smaller partial payments for less severe conditions. [9]
The ABI publishes minimum standards for how its members word the most common definitions, so that the core conditions are described consistently across the market. [6] Policies can go beyond those minimums, and two policies that both “cover cancer” can still pay in different circumstances.
What it does not do is pay for treatment, replace your income month by month, or pay for illnesses that are not on the list. It also has no cash-in value: if you stop paying, the cover stops. Our guide to what critical illness cover is covers definitions, survival periods and combined policies in more depth.
| Question | Critical illness cover | What to bear in mind |
|---|---|---|
| How does it pay? | One lump sum to you | Paid once per claim; some policies allow further claims for different conditions |
| What triggers it? | A diagnosis that meets the policy definition | Severity or stage may need to be reached |
| Does it pay for treatment? | No | Private medical insurance is the product for treatment |
| Does it replace income? | Not directly | The lump sum can be used to cover lost income for a period |
| Any cash-in value? | No | Premiums are the cost of the protection while it runs |
| Can you choose how to spend it? | Yes, subject to the policy terms | Mortgage, bills, adaptations or simply time off work |
When critical illness cover tends to be worth more
The value of a lump sum depends on the gap it fills. The situations below are where that gap is usually widest.
- You have a partner or children who depend on your income.
- You have a mortgage or rent that would be hard to keep paying on a reduced income.
- Your employer pays only Statutory Sick Pay, or you are self-employed and get no sick pay at all.
- Your savings would last weeks rather than months if your income stopped.
- You would want to make changes to your home, pay for help or take extended time off to recover.
For employees, the statutory floor is Statutory Sick Pay: £123.25 a week, or 80% of normal weekly earnings if lower, paid for up to 28 weeks. [3] For most households that is a small fraction of normal outgoings. Self-employed people do not receive it at all.
Serious illness is also not a remote possibility. Cancer Research UK estimates that around half of people in the UK born after 1960 will be diagnosed with some form of cancer in their lifetime, [4] and the British Heart Foundation’s factsheet sets out the number of people living with heart and circulatory diseases in the UK. [5] A diagnosis is not the same as a successful claim, but these figures explain why people take the question seriously.
When it may be worth less
Critical illness cover can be worth less, or nothing at all, in some situations. Being honest about these is part of a fair answer.
- You have no dependants and no debts, and enough savings to cover a long period off work.
- Your employer already provides group critical illness cover or very generous long-term sick pay.
- The premium would stretch your budget so far that you might stop paying and lose the cover.
- What you really need is a regular income for any illness that stops you working — which is the job of income protection.
It is also worth checking what you already hold. Some mortgage-linked life policies include critical illness cover, and some employee benefits packages include it. Doubling up is not always wasteful, but it should be a deliberate choice.
Do critical illness policies pay out?
A common reason people doubt whether the cover is worth it is the fear that insurers do not pay. The industry figures show substantial sums paid every year, [1] [2] but individual claims can still be declined.
The Financial Ombudsman Service explains that when it looks at a declined critical illness claim, it considers whether the diagnosis met the policy definition and, where the insurer says the application was inaccurate, whether the insurer acted fairly. [7] The Consumer Insurance (Disclosure and Representations) Act 2012 requires you to take reasonable care not to misrepresent your medical history when you apply, and limits what an insurer can do if an error was honest and reasonable. [8]
The Ombudsman publishes yearly complaints data by product, which shows how many protection complaints it receives and how many it upholds. [10] The practical lesson is simple: answer every application question fully, keep a copy of what you said, and read the definitions for the conditions that worry you most. Our guide do critical illness policies pay out? goes further.
What drives the cost
Whether something is worth it depends on its price, and critical illness premiums vary widely. The main factors are your age, health and smoking status, the lump sum you choose, how long the cover runs, and whether the premium is fixed or can be reviewed. We do not publish average prices because they are rarely comparable; a quote based on your own details is the only reliable figure.
| Factor | Effect on price | Why it matters for value |
|---|---|---|
| Age when you apply | Older usually costs more | Starting earlier can lock in a lower guaranteed premium |
| Smoking status | Smokers usually pay more | Must be declared accurately to keep claims safe |
| Health and family history | Can add exclusions or loadings | Exclusions change what the policy is worth to you |
| Size of the lump sum | Higher sum, higher premium | Match it to a real need, not a round number |
| Length of cover | Longer term usually costs more | Often matched to a mortgage or children’s ages |
| Guaranteed or reviewable premium | Reviewable starts lower but can rise | Affects whether you can keep paying long term |

A five-question test for whether it is worth it for you
- If your income stopped tomorrow, how many months could your household keep paying its essential bills?
- What would your employer pay you, and for how long? Check your contract rather than guessing.
- Who depends on your income, and what would change for them?
- Do you already have critical illness cover through a mortgage policy or your employer?
- Could you comfortably keep paying the premium for the whole term?
If your answers show a large gap between what you would have and what you would need, a lump sum may be valuable. If they show you are already well protected, the money might do more good elsewhere. Our guide on how much critical illness cover you need walks through the arithmetic.
Alternatives and combinations to weigh
Critical illness cover is one of several tools. Income protection pays a regular monthly income if any illness or injury stops you working, after a waiting period you choose. Life insurance pays out on death and is often combined with critical illness cover in one policy. Private medical insurance pays for eligible private treatment. Each fills a different gap, which is why many people compare them together — see critical illness cover vs income protection.

Common questions
- Is critical illness cover worth it if I have savings?
- It depends on how much you have and what you want those savings to do. A serious illness can mean months away from work while the mortgage, bills and family costs continue. Savings that look comfortable as an emergency fund can be used up surprisingly quickly in that situation. Some people are happy to rely on savings and accept the risk; others would rather keep their savings for retirement, children or a home and use insurance to protect them. A useful test is to divide your accessible savings by your essential monthly outgoings, after any sick pay, and see how many months that buys. If the answer is short, a lump sum could fill the gap. If it is long, the cover may add less.
- Is critical illness cover worth it if my employer already provides it?
- Check exactly what your employer provides before deciding. Group critical illness cover is often a fixed amount or a multiple of salary, it usually ends when you leave the job, and the list of conditions may differ from an individual policy. If your employer cover is modest, or you expect to change jobs, a personal policy can give protection that stays with you. If your employer cover is generous and you plan to stay, the case for a personal policy may be weaker. Ask your HR team for the policy summary, including the conditions covered, the amount and how the benefit is taxed. Group cover is usually reported as a benefit, so it can also affect your tax.
- Do insurers really pay critical illness claims?
- Insurers pay large sums every year. The Association of British Insurers reported £7.84 billion paid across life, critical illness and income protection claims in 2025, [1] and £8 billion in 2024. [2] Individual claims can still be declined, most often because the illness did not meet the policy definition, or because the insurer says the application did not give accurate medical information. If a claim is declined you can complain to the insurer and then, free of charge, to the Financial Ombudsman Service, which considers whether the definition was applied fairly and whether any non-disclosure was handled lawfully. Answering application questions carefully is the best way to protect a future claim.
- Is critical illness cover worth it for a single person with no children?
- It can be, although the reasons are different. With no dependants, life insurance may matter less, but a serious illness still affects your own income and housing. A single person has no second earner to fall back on, so if you have a mortgage or rent and limited savings, a lump sum could make it easier to keep your home while you recover. On the other hand, if you rent cheaply, have strong savings or excellent sick pay, you might decide the risk is one you can carry yourself. Many single people also look at income protection, which replaces part of your earnings monthly for any illness that stops you working, rather than only listed conditions.
- Is it better to have critical illness cover or income protection?
- They do different jobs, so the better choice depends on the gap you want to fill. Critical illness cover pays one lump sum on a qualifying diagnosis of a listed condition, which suits clearing or reducing a mortgage or paying for one-off costs. Income protection pays a monthly income if any illness or injury stops you working, after a deferred period, and can continue until you return to work or the policy ends. Income protection can respond to conditions that critical illness cover does not list, such as many back problems or mental health conditions, but it pays nothing if you keep working. Some people hold both, weighting their budget towards whichever gap worries them most.
- What reduces the value of a critical illness policy?
- Several things can make a policy worth less than it first appears. Exclusions added because of your medical history may remove the very conditions you are most concerned about. A low lump sum may not cover enough months of lost income to make a real difference. Reviewable premiums can rise, making the policy harder to keep. A term that ends before your mortgage or before children become independent can leave a gap later on. And inaccurate application answers can put a future claim at risk. Reading the key features document, the definitions and any personal exclusions before you buy is the simplest way to understand what the policy is genuinely worth to you.
