What is critical illness cover?
It's an insurance policy that helps protect you if you become critically ill during the policy term. It pays out a tax-free lump sum that you can use however you like – whether that’s to help cover health-related costs, monthly expenses, or lost income while you get better.
Your policy could also help you take more control of your health and wellbeing right away. Through Aviva DigiCare+, our smartphone app powered by Square Health, you can access annual health checks, discounts on gym membership and home fitness, advice on nutrition, counselling for mental health and more. So you have the tools and services you need to enjoy life today. Please be aware the benefits of DigiCare+ do not form part of your cover and they could be changed, or removed in the future.
Children’s cover
We’ll pay if your child is diagnosed with or has surgery for a critical illness
Aviva DigiCare+ app
Offers mental health support, advice on nutrition and access to other health and wellbeing benefits
Standalone policy
You can buy life and critical illness cover at the same time. As they’re separate policies, both could pay out
How does critical illness cover work?
You pay monthly premiums for the policy term, from 5 to 50 years, and if you're diagnosed with one of the 53 conditions we cover during that time, we'll pay out. Our policy also includes a children's benefit that covers any children you have at no extra cost.
Do you need critical illness cover?
You can’t know what’s around the corner for your health, but you can make sure you’re prepared financially.
Think about expenses you’d need to cover if you were critically ill and couldn’t work. It might be monthly outgoings like rent payments and general bills, or instalments on a loan or a repayment mortgage. If you don’t have savings to fall back on, getting cover can help take financial worry away while you’re recovering or having treatment.
How much critical illness cover do you need?
It depends on things like what you want to cover, how much you’re looking to pay each month, and for how long. Because our critical illness plan isn’t combined with life insurance, we’re flexible. Over half of our customers pay just £17.50 a month or less for our critical illness cover 1.
Our different types of cover
We offer different types of critical illness cover: level cover and decreasing cover. The type of cover you want may depend on what you want to protect, and how much you’d like to pay each month.
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 the effects of inflation
You can choose to make your cover amount increase in line with inflation. This ensures that the lump sum won't be worth less in the future because of the rise in the cost of living. With this option, the amount of cover and the amount you pay can both go up each year.
The maximum annual increase is 15% to your premium and 10% to your cover amount 2.

Decreasing cover
This type of cover might be used to help pay off a repayment mortgage, or other debts or loans, if you're diagnosed with a critical illness during the policy term.
- It lasts for a specific amount of time, and your monthly premiums are fixed, unless you make a change to your policy
- It usually costs less than level cover, as the value of the loan or mortgage you're paying off gradually decreases over time, and so does the cover
