What Is Children's Critical Illness Cover?

Children's critical illness cover pays a tax-free lump sum if your child is diagnosed with a serious medical condition specified in the policy. It is designed to help parents cope with the financial impact of a child's serious illness, from time off work to travel to specialist hospitals, accommodation costs, and home adaptations.

The good news is that children's CIC is most commonly available as a free add-on to an adult critical illness policy. If you already have (or are considering) CIC for yourself, your children may be covered at no extra cost. For a general overview of how CIC works, see our guide on what is critical illness cover.

Key fact: Children's CIC is often included free with a parent's policy. In 2024, Aviva paid £7.6 million in children's critical illness claims across 361 families, with an average payout of £21,321. Children are typically covered from 30 days old to age 18–23. Claiming for your child does not affect the parent's main cover.

How Does Children's CIC Work?

Children's critical illness cover works in much the same way as adult CIC, but with some important differences. When included as a free add-on to a parent's policy, the cover is automatic, you do not need to name each child individually, and new children born or adopted during the policy term are typically covered automatically.

The key points to understand are:

What Conditions Are Covered for Children?

The list of conditions covered for children varies by insurer but typically includes conditions that are particularly relevant to younger people. Here is a summary of the most commonly covered children's conditions:

Condition Typical Coverage Notes
Cancer (including childhood leukaemia)Full payoutMust meet severity definition; some early-stage cancers may qualify for partial payment
Meningitis with lasting complicationsFull payoutMust result in permanent neurological deficit or other lasting effects
Cerebral palsyFull payoutMust be diagnosed after the policy start date
Muscular dystrophyFull payoutConfirmed diagnosis by a consultant
Heart surgeryFull payoutOpen-heart surgery to correct a structural defect
Major organ transplantFull payoutPlaced on official transplant waiting list or received a transplant
Type 1 diabetesPartial or fullCoverage varies by insurer; some include as partial payment
BlindnessFull payoutPermanent and irreversible loss of sight in both eyes
DeafnessFull payoutPermanent and irreversible loss of hearing in both ears
Severe burnsFull payoutThird-degree burns covering a specified percentage of body surface area

For a comprehensive breakdown of all conditions covered by CIC (adult and children), see our guide on conditions covered by critical illness insurance.

Important: Pre-existing conditions are not covered. If your child was diagnosed with or showed symptoms of a condition before the policy started, that condition will be excluded. This applies even if you did not know about the condition at the time of application, the key date is when symptoms first appeared, not when the diagnosis was made.
Key fact: L&G also offers £100 per night hospital benefit, a £4,000 funeral benefit, and £1,000 childcare payment as part of their children's CIC add-on. These additional benefits can provide practical financial support during what is already a difficult time for families.

Free Add-On vs Standalone Children's CIC

There are two ways to get critical illness cover for your children: as a free add-on to your own policy, or as a separate standalone policy.

Free add-on (most common)

The majority of enhanced and comprehensive adult CIC policies include children's cover at no additional cost. This is the simplest and most cost-effective option for most families. Key features:

Standalone children's CIC

Standalone policies are less common but offer higher cover amounts. They may be worth considering if:

Tip: For most families, the free add-on provides sufficient cover. Before purchasing a standalone children's policy, check whether upgrading to an enhanced adult CIC policy (which includes children's cover free) might be more cost-effective overall. See our guide on family critical illness cover for a comparison.

Age Limits and Eligibility

Children's critical illness cover typically applies from birth (or 30 days old, depending on the insurer) up to a maximum age. The age limits vary by provider:

Once your child exceeds the age limit, they are no longer covered under your policy. They would need to take out their own adult CIC policy at that point.

How Much Does Children's CIC Pay Out?

The payout amount for children's CIC depends on whether you have the free add-on or a standalone policy:

Policy Type Typical Payout Notes
Free add-on (standard)£10,000 – £15,000Fixed amount per child; does not reduce parent's cover
Free add-on (enhanced)£20,000 – £25,000Higher payout with premium policies; some cap at 50% of parent's sum assured
Standalone policy£25,000 – £100,000+You choose the cover amount; comes with its own premium

The Financial Impact of a Child's Serious Illness

While no parent wants to think about their child being seriously ill, understanding the financial reality helps explain why children's CIC exists. When a child is diagnosed with a serious condition, the costs extend far beyond medical treatment:

Real perspective: Research by children's charities suggests that families face average additional costs of £600 per month when a child is being treated for a serious illness. A children's CIC payout of £25,000 could cover these additional costs for over three years, providing a meaningful financial buffer during an incredibly difficult time.

How to Claim on Children's CIC

The claims process for children's CIC is straightforward and follows the same general procedure as an adult claim:

  1. Contact your insurer, notify them of your child's diagnosis as soon as possible. Most insurers have dedicated claims teams who can guide you through the process.
  2. Complete the claim form, the insurer will send you a claim form to complete. As the policyholder, you submit the claim on your child's behalf.
  3. Provide medical evidence, your child's medical team will need to provide reports confirming the diagnosis. The insurer may also request access to your child's medical records.
  4. Insurer review, the insurer assesses the claim against the policy definitions to confirm the condition meets the required criteria.
  5. Payout, if approved, the lump sum is paid directly to you (the policyholder). Most claims are settled within four to eight weeks.
Remember: A children's CIC claim does not end your own policy. Your adult critical illness cover continues in full after a successful children's claim. This is one of the key advantages of the add-on structure. To understand whether CIC is the right choice for your family overall, see our guide on is critical illness cover worth it.

Which Insurers Offer the Best Children's CIC?

The quality of children's CIC varies significantly between insurers. When comparing policies, look for:

Frequently Asked Questions

Children's critical illness cover pays a tax-free lump sum if your child is diagnosed with a serious medical condition specified in the policy. It is most commonly included as a free add-on to a parent's critical illness policy, though standalone options exist with some providers.
In most cases, yes. The majority of UK insurers include children's critical illness cover at no extra cost when you take out an enhanced or comprehensive adult CIC policy. The cover typically applies to all of your children automatically. Standalone children's CIC, where available, does come with a separate premium.
Children's CIC typically covers conditions including cancer (such as childhood leukaemia), meningitis with lasting complications, cerebral palsy, muscular dystrophy, heart surgery, organ transplant, blindness, deafness, severe burns, and type 1 diabetes. The full list varies by insurer. See our conditions covered guide for more detail.
When included as a free add-on to a parent's policy, children's CIC typically pays a fixed lump sum of between £10,000 and £25,000, depending on the insurer. Some providers cap the payout at a percentage of the parent's sum assured. The parent's main policy continues after a children's claim.
No. One of the key benefits of children's CIC as an add-on is that claiming for your child does not reduce or end your own cover. The children's payout is separate, and your policy continues as normal for any future adult claim.
Most insurers cover children from birth (or 30 days old) up to age 18, or up to age 21 if they are in full-time education. Some policies extend to age 23. The exact age limits vary by provider, so check your policy terms.
Standalone children's CIC policies are less common in the UK market but do exist through some specialist providers. These policies offer higher cover amounts than the free add-on but come with their own premium. Most parents find that the free add-on included with their own CIC policy provides sufficient cover.
Most insurers cover adopted children and stepchildren who are legally part of your family and live with you. The specific requirements vary by insurer, so check the policy terms or ask your adviser to confirm before taking out cover.
It depends on the condition and when it was diagnosed. Most policies exclude conditions that were diagnosed or known about before the policy started. However, some congenital conditions that are not diagnosed until after the policy has been in force may be covered if they appear on the conditions list.
The claim process is similar to an adult claim. You contact your insurer, complete a claim form, and provide medical evidence of your child's diagnosis. The insurer reviews the claim against the policy definitions. Most children's claims are processed within four to eight weeks.
Yes, in most cases. If children's CIC is included as an add-on to your policy, each child is covered individually. A claim for one child does not prevent a claim for another child. However, some policies limit the total number of children's claims or the total amount payable.
Yes, especially since it is usually free with an enhanced adult CIC policy. While the probability of a child developing a serious illness is low, the financial impact on a family can be enormous, including time off work for parents, travel to specialist hospitals, and accommodation costs during treatment.
Children's CIC typically ends when your child reaches 18 (or 21 to 23 if in full-time education, depending on the insurer). After that, they would need to take out their own adult critical illness policy if they want continued cover.
Some enhanced policies cover certain complications arising from premature birth, but this varies significantly by insurer. Conditions such as cerebral palsy may be covered if diagnosed after the policy start date, but complications that are a direct result of prematurity may be excluded by some providers.
Children's CIC typically covers a different set of conditions that are more relevant to younger people, such as cerebral palsy, muscular dystrophy, and childhood cancers. The payout amount is lower (usually capped at £10,000 to £25,000), and importantly, a children's claim does not end the parent's policy.
