Critical illness cover

Financial support while you recover from a critical illness

We'll cover you for 52 listed conditions

What is critical illness cover?

Critical illness cover pays a sum of money if, during the policy term, you’re diagnosed with a condition covered by your policy. You usually need to survive a short period after you’re diagnosed to get the payout.

How our critical illness cover works

Our Critical Illness Plan covers 52 conditions, all listed in our policy conditions.

Lump sum payment

Some conditions will pay out on diagnosis, while for others, your condition must have reached a certain level or you’ve had named treatments.  You’ll need to survive 10 days after you’re diagnosed. Any claim will need to be made during the term of the policy.

We’ll pay you a lump sum if we accept your claim. You can find full details of each definition in the policy conditions

You’ll pay a monthly premium

Your monthly premium depends on things like your personal circumstances, medical history, policy term and the level of cover you choose.  

 

Child cover and additional benefits

The cover automatically includes your children (aged 30 days to 18 years, or 21 years if they’re in full‐time education.) We don’t cover children for terminal illness.

You can claim for 11 additional critical illnesses (including low grade prostate cancer and less advanced cancer of the breast).

These benefits pay a lower amount. If we pay out a successful claim your policy will continue.

Important to know

It's worth noting that this is not a savings or investment product and will only pay out if a successful claim is made. If you stop paying your premiums or cancel your policy , the policy will end and you'll get nothing back.

Our critical illness plan does not pay out on death.

If you have a joint policy and one person dies, the policy will still cover the other person.

The policy only pays out once, for a listed critical illness unless it’s a children’s claim or an additional critical illness claim.

Who can apply for our Critical Illness Plan?

You must be aged 18 to 64 to apply. For a joint policy, the maximum age applies to the oldest person covered.

When you apply you must:

  1. be in the UK, with the legal right to live in that jurisdiction, and
  2. 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 does our critical illness insurance cover?

Cancer (excluding less advanced cases)

Each person covered by the policy can claim for each of these conditions once. If you claim for an additional critical illness, your policy will continue. It won’t affect what we pay for any other benefit in the future.

Children's benefit 

We also include a children’s benefit in our critical illness cover. This benefit covers all your children (natural, step and legally adopted), including any future children. Your children need to be aged between 30 days and their 18th birthday, or their 21st birthday if they’re in full time education.

If you claim for children’s benefit, your policy will continue. It won’t affect what we pay for any other benefit in the future.

 

Children’s critical illness cover

If during the policy term, any of your children:

  • are diagnosed with one of the critical illnesses or additional critical illnesses we cover (excluding terminal illness), and
  • survive for 10 days after diagnosis,

we’ll pay you the lower amount of either:

  • £25,000, or
  • 50% of the cover amount.

We won’t pay out for children’s critical illness if the:

  • critical illness was present at birth (whether diagnosed or not)
  • child had symptoms of the critical illness before they were covered by the policy.

For more information, please read the policy conditions.

 

Children’s death benefit

If any of your children die during the policy term, we’ll pay £5,000. We’ll pay the children’s death benefit on top of any payment we make for children’s critical illness. We’ll pay children’s critical illness benefit and children’s death benefit once for each child.

Types of critical illness cover you can get with Aviva

The type of cover that’s right for you depends on what you want to protect and how much you’re comfortable paying each month.

You can choose between level cover, where the payout stays the same, or decreasing cover, where the amount you’ll get drops over time. 

Level cover

With level cover, you choose how much cover you want and how long you’d like the cover to run for. Both your cover amount and monthly payments stay the same until the policy ends (unless you choose to protect against inflation)

Level cover could be a good option if you want to give your loved ones ongoing financial support, as the lump sum could help cover things like:

  • Your salary
  • Any additional health and living costs
  • Rent
  • Continue to make mortgage payments
  • Children’s school fees or other childcare costs

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 you hold the policy. 

The amount of cover gradually goes down, usually in line with what you owe. Like level cover, it lasts for a set term, and your monthly payments stay the same 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. You’ll owe less money over time so the potential payout reduces too.
