Standalone child-only health insurance is rare in the UK — insurers almost always cover children as additions to an adult's policy. Adding a child typically costs around £15–£30 a month, and some insurers discount second and subsequent children or run free-child offers. The claims that matter most for kids: ENT surgery, physio and teenage mental health support.

Can you insure a child on their own?
Mostly, no — and it's worth saying plainly because plenty of parents search for exactly this. Mainstream UK insurers don't generally sell standalone policies to under-18s; a child is added as a dependant on a parent's or guardian's policy instead. So the real question isn't "which child policy?" but "which adult policy handles children best?" — and there the differences are genuine: what a child addition costs, whether siblings are discounted, and how long children can stay on the policy (commonly to 18–25, longer in full-time education with some insurers).
The practical upside of the add-on model: children are typically underwritten on the same basis as you, they benefit from the same hospital list and digital GP access, and their premium is a fraction of an adult's because children claim less often — just differently.
What adding a child costs
As a working figure, adding one child to a comprehensive adult policy typically costs around £15–£30 a month depending on insurer and cover level. That's consistent with the family maths we use across the site: UK average cover for a family of four runs about £167 a month — roughly a couple's £146 plus modest child premiums.
| Set-up | Typical monthly cost | Note |
|---|---|---|
| One adult (30s, healthy) | from ~£38 | Base policy the child attaches to |
| Couple | ~£146 | UK average, 2026 |
| Family of four | ~£167 | Children add relatively little |
| Each additional child | ~£15–£30 | Often discounted for siblings |
Then the offers. Several insurers have run promotions where a second or subsequent child is discounted or covered free when at least one parent is insured — the detail varies by insurer and changes over time, so treat any specific offer you've seen as something to verify at quote stage rather than a permanent fixture. For larger families these offers meaningfully change which insurer is cheapest, which is exactly the kind of thing comparison is for.
What children actually claim for
Children's claims don't look like adults'. Forget cardiology and joint replacements — the childhood claims that make cover earn its keep cluster in a few areas:
- ENT surgery. Grommets for glue ear, tonsillectomy and adenoid removal are the classic childhood operations — and ENT is one of the slowest NHS specialties, with a 14.8-week median wait and 1 in 12 children's families waiting far longer. Privately, consultation to surgery typically runs a few weeks.
- Physiotherapy and fractures follow-up. Sporty kids generate physio referrals; policies with outpatient cover pick these up quickly.
- Teenage mental health. Increasingly the claim parents value most: private assessment and talking therapies while NHS CAMHS queues stretch. Check the policy's mental health cover — it varies more between insurers than almost anything else.
- Dermatology and allergies. Eczema flare referrals, suspicious moles, allergy investigation — quick outpatient work where a 11.3-week NHS dermatology median feels long with an uncomfortable child.
One honest caveat: A&E, routine immunisations and ongoing care for chronic childhood conditions stay with the NHS — private cover is for the referrals, investigations and elective procedures in between.
Compare family policies that get children right
The paediatric waiting context
The NHS is brilliant with sick children — emergency and specialist paediatric care in the UK is world-class and no private policy replaces it. The waiting is a different story. Children sit on the same 7.3 million-treatment waiting list as everyone else, and community paediatric services — hearing, speech, development assessments — carry some of the longest queues in the system. For a seven-year-old, two school terms waiting for grommets is a meaningful chunk of childhood spent not hearing properly.
That's the honest case for covering children: not that the NHS won't treat them, but that a child's timescales are different. Privately, the typical journey is a paediatric consultation within days and routine surgery inside 2–6 weeks.
Choosing a policy with children in mind
If children are the main reason you're buying, weight your comparison differently. Prioritise outpatient cover (most child claims are consultations, tests and therapy rather than big surgery), check the mental health benefit in detail for the teenage years ahead, and confirm the insurer's hospital list includes paediatric units within reach — not every private hospital treats children, and some procedures on younger children are only done where paediatric anaesthetists operate.
Also check the boring-but-important terms: the age children roll off the policy (and on what underwriting terms they can take out their own), whether a newborn can be added without underwriting inside a set window, and how sibling discounts stack. A policy that's £10 a month dearer but keeps a student covered to 25 can easily be the better buy.
Finally, mind the excess mechanics. Some insurers apply the excess per person per year — so a household where two children each have a small outpatient claim pays it twice — while others apply it per policy. For families whose claims are lots of small consultations rather than one big operation, a per-policy excess or a lower excess is often worth a slightly higher premium. It's the kind of detail that never makes the marketing page but decides what a year of childhood claims actually costs you.
Frequently asked questions
Can you get health insurance for a child on its own in the UK?
Rarely — mainstream UK insurers don't generally sell standalone policies to under-18s. Children are added as dependants on a parent's or guardian's policy instead, typically for around £15–£30 a month each. The practical question becomes which adult policy handles children best on price, sibling discounts and how long kids can stay covered.
How much does it cost to add a child to health insurance?
Typically around £15–£30 a month per child on a comprehensive policy, depending on insurer and cover level. The family maths bears this out: a couple averages about £146 a month while a family of four averages about £167 — children add relatively little. Sibling discounts and free-child offers can lower it further where available.
Which insurers offer free child cover?
Several insurers have run offers discounting or waiving premiums for second and subsequent children when a parent is insured — but the details change over time and vary by product, so verify any offer at quote stage rather than relying on what you've read. For families with three or more children, these offers can genuinely change which insurer works out cheapest.
What do children actually claim for on private health insurance?
The big four: ENT surgery (grommets, tonsils, adenoids — against a 14.8-week NHS ENT median), physiotherapy for sports injuries, teenage mental health assessment and therapy, and dermatology or allergy referrals. Children's claims are mostly outpatient-shaped, which is why outpatient and mental health cover matter more than headline surgical limits when choosing for kids.
Does children's health insurance cover grommets and tonsillectomy?
Yes — provided the condition develops after the child joins the policy. Grommets and tonsillectomy are the classic childhood private claims, typically done privately within a few weeks of consultation versus a 14.8-week NHS ENT median wait. A child added with existing glue ear or recurrent tonsillitis would usually have that condition excluded until the standard symptom-free period passes.
Does private health insurance cover children's mental health?
Most comprehensive policies include mental health cover that extends to child dependants — typically private assessment and talking therapies — but the benefit varies more between insurers than almost any other. Given NHS CAMHS pressures, many parents rate this the most valuable part of a child's cover. Check session limits, age rules and whether inpatient mental health care is included.
Until what age can children stay on a family health insurance policy?
Commonly to age 18–25, with several insurers extending the upper end for children in full-time education — exact rules vary by insurer. When they roll off, some insurers let them start their own policy on continued underwriting terms, keeping a clean claims record intact. If you have teenagers, this transition term is worth checking before you buy.
Do pre-existing conditions apply to children on health insurance?
Yes — children are underwritten like adults. Under a moratorium, anything a child has had symptoms, treatment or advice for in the look-back period is excluded until the usual symptom-free period passes. This is the argument for adding children young, before conditions accumulate on their record, and for adding newborns inside any no-underwriting window the insurer offers.
Is private health insurance for children worth it when the NHS is free?
The NHS is excellent for children's emergency and specialist care, and cover doesn't replace that. What you're buying is time on elective and outpatient queues: grommets in weeks not terms, physio promptly, mental health assessment without the CAMHS wait. At £15–£30 a month per child, it's one of the cheaper parts of a family policy relative to how much parents value the claims.
Can grandparents pay for a grandchild's health insurance?
The child still needs to sit on a parent's or guardian's policy in most cases, but who pays the premium is flexible — grandparents funding the family policy's child additions is common and uncontroversial. If the goal is a gift, paying for the whole family policy or ring-fencing money towards it works just as well.
