Child health insurance: private cover for your children, explained

Child health insurance gives your son or daughter fast access to private healthcare when they need a specialist, a scan or an operation, instead of waiting on an NHS list. In the UK, child health insurance is usually added to a parent's policy as family cover rather than bought on its own, and on some health insurance policies adding a child costs far less than you might expect.

Waiting lists for children's services such as ENT, orthopaedics and mental health support can be long, and for a parent watching a child in pain or struggling at school, every week matters. Private health insurance for children is designed to shorten that wait and give you choice over the specialist and hospital.

We compare health insurance for children and families across the leading UK health insurers, including Bupa, AXA Health, Aviva, Vitality and WPA, and explain the differences in plain English. Using us costs nothing extra; the commission is already in the premium.

What is child health insurance?

Child health insurance is private medical insurance that covers a child for the cost of private treatment for acute conditions: illnesses and injuries that are likely to respond to treatment, such as recurrent tonsillitis, glue ear needing grommets, a broken bone that needs surgery, or investigations for persistent symptoms. Most health insurance policies also include cancer cover, and many offer mental health support for children and young people.

Children's health insurance does not replace the NHS. Emergency treatment in A&E, routine GP visits, vaccinations and long-term chronic conditions such as asthma or type 1 diabetes generally stay with the NHS. Where private health insurance helps is getting from a GP referral to a specialist, diagnosis and treatment quickly.

Can I add my child to my health insurance?

Yes. The most common way to get private health insurance for children is to add your child to a family health insurance policy alongside one or both parents. Most health insurers let you add children when you take out cover, at renewal, or when a baby is born.

Adding a newborn is usually straightforward, and some insurers will cover a new baby without medical underwriting if you add them within a set period after birth and the parent has been on the policy for a minimum time. Check the terms and conditions before the baby arrives, because the window is short.

Can I get private health insurance just for my child?

Sometimes. A few health insurers will insure a child on their own policy with a parent as the policyholder; others require at least one adult on the policy. If you have cover through work, check first whether your employer's scheme lets you add children as dependants, which is often cheaper than a separate child-only policy.

Is it worth getting private health insurance for children?

For many UK families, yes. The strongest reasons parents give for child health insurance are:

It may be less worth it if your budget is tight and you would rather protect the adults first, or if your child already has a condition that would be excluded. A good broker will tell you honestly when the cover will not add much.

Can I get health insurance for my child with a pre-existing condition?

You can usually get cover, but the pre-existing condition itself is likely to be excluded. With moratorium underwriting, a condition your child has had symptoms of, treatment for or advice about in the last five years is excluded until they go two years on the policy without needing help for it. With full medical underwriting, you declare the medical history up front and the insurer lists any exclusions.

For a child with a history of something like eczema, grommets or a past fracture, the choice of underwriting can change what is covered. This is worth talking through with a broker before you apply, rather than discovering an exclusion when you claim.

Age limits: how long can children stay on the policy?

Each insurer sets its own age limits for children. Many cover a child until they reach their late teens or early twenties, and some extend cover for young adults in full-time education. Once a child passes the limit, they can usually move onto their own policy, often without fresh underwriting if they apply quickly. Check the age limits when comparing, especially if you have teenagers.
