What is critical illness cover?
Critical illness cover is designed to pay out a lump sum if you are diagnosed with a critical illness covered by the policy during the policy term. It does not pay out if you die during a specified period. There is no cash in value at any time.
How our critical illness cover works
-
Lump sum payment
We'll pay a lump sum if you're diagnosed with one of the 52 conditions listed in our policy but you must survive for 10 days following the diagnosis.
Dependent on the definition of the critical illness, we may pay on diagnosis only, when the condition has progressed to a specified severity or when named treatments or surgeries are performed. There is no cash-in value at any time.
-
Pay a monthly premium for the policy term
The premium you pay will depend on a number of things including your personal circumstances, medical history, policy term and cover amount you choose. As at June 2025, over half of our customers paid just £20 or less for our Critical Illness Plan.
-
Pair up your policies
You can buy life and critical illness cover at the same time. The policies are separate, so they could both pay out.
-
Cover for your kids
We'll pay up to £25,000, or 50% of the cover amount (whichever is lower), for children diagnosed with critical illnesses (not terminal illness).
Are you eligible for critical illness cover?
You must to be aged between 18 and 64 to apply for this policy. For a joint policy, the maximum age applies to the oldest life covered.
At the time you complete the application you must:
- be in the UK, with the legal right to live in that jurisdiction, and
- consider your main home as being in the UK, and have no current intention of moving anywhere else permanently.
The UK does not include the Channel Islands, the Isle of Man or Gibraltar.

What our critical illness insurance covers
If you already have critical illness cover with us, check what conditions you’re covered for in your policy documents, as it may be different from what’s detailed below.
These are included:
Important to know:
- If you’re diagnosed with a critical illness outside the policy term
You’re only covered during the policy term.
- If you die
Your policy will end and we won’t pay out. This is also the case if you die within 10 days of diagnosis. If you have a joint policy and one person dies, the policy will still cover the other person. - Not paying your premium
If you stop paying premiums or cancel your policy, your cover will end and you won’t get anything back. This is no cash-in value at any time. - If you’re diagnosed with a critical illness not listed in our policy
You’re only covered for the conditions listed. - This policy ends if it pays out
The policy only pays out once, unless it’s a children’s claim or an additional critical illness claim.
Why choose our critical illness cover?
How to choose the type of critical illness cover that’s right for you
It's all down to what you want to protect and how much you're willing to set aside each month. Pick between level cover (a set amount which you can also protect from inflation) or decreasing cover (the amount you’ll get drops over time).
Level cover
With level cover, you choose the cover amount and how long you want the cover to run for. The amount of cover and the amount you pay each month stays the same until your policy ends.
Level cover could be a good option if you're looking to help maintain a loved ones' living standards, and the lump sum can help to cover things like:
- Your salary
- Any additional health and living costs
- Rent payments
- Continue to make mortgage payments
- Children’s school fees or other childcare costs
Protecting your cover from inflation
You can choose to make your cover amount increase in line with inflation. This means that your monthly payments may rise, and ensures the lump sum won’t be worth less in the future because of the rise in the cost of living.
If you choose this option, the maximum annual increase would be 15% to your premium and 10% to your cover amount. Footnote [3] The cover amount increases in line with the Consumer Prices Index (CPI), calculated over 12 months. To calculate the increase to your premium, we multiply what you pay by 1.5 and the percentage increase in CPI. If there’s no increase in the CPI there’s no change to your cover or premium over a 12 month period.
Decreasing cover
This could be a great option to help pay off a mortgage, debt or other loans if you're diagnosed with one of the defined illnesses while the policy’s active.
- Just like level cover, it has an expiry date, and your monthly payments are set in stone unless you change your policy
- In general, decreasing cover is lighter on your wallet than level cover as it's only there to pay off loans and debts you’re chipping away at. The payout amount won't need to be as high if you claim as you'll owe less money over time.

Transcript for video Our critical illness cover
A lot of us think we'll never be diagnosed with a critical illness but in reality it could happen to anyone.
How would you and your family cope financially if you became ill? Whether it's paying for treatment or helping to cover your salary while you get better, our Critical Illness Plan could make a big difference if you're diagnosed with a life changing illness.
We cover over 50 conditions including nearly all types of cancer, as well as heart attacks and strokes.
We offer different types of cover - level cover and decreasing cover.
With level cover, what you pay each month stays the same for the whole term of the policy, and so does the cover amount. And if you'd prefer your cover amount to rise with the cost of living, you can choose to protect it against the effects of inflation, which means that what you pay will also increase over time.
Decreasing cover works like a repayment loan, with a fixed interest rate. So, the value of your cover decreases gradually, but the amount you pay stays the same.
Our Critical Illness Plan also includes children's cover, so the whole family can stay protected.
Your cover can last between 5 and 50 years, or up until your 75th birthday.
When it comes to how much cover you'll need, everyone's different.
How much would you need to cover your monthly outgoings? Think about everyday costs like household bills and childcare. Or, how would you pay for any unexpected treatment costs. So that you and your family were able to live life as normally as possible.
Even a small amount of critical illness cover could allow you to take the time you need to recover or take a well deserved holiday.
At Aviva, our cover is designed with you in mind, with flexible cover length, children's cover and lump-sum pay-outs.
We're here when you need us most.
