Children’s private health insurance in the UK

Adding your kids to a policy is usually the cheapest part of family cover — but what it actually pays for is narrower than most parents expect. It shines on the quick, one-off problems of childhood; it is not a route around the NHS for the long-term conditions that worry parents most. Here is the honest version for 2026.

Typical private health insurance costs

Independent research — typical UK costs from ABI, Which? and MoneyHelper published data.

The short version

  • Adding a child to an existing adult or family policy usually costs around £10–£30 a month per child in 2026; a standalone child-only policy is dearer, roughly £30–£70+.
  • Several big insurers price on the eldest child, so a second or third child often adds little or nothing.
  • Cover is built for new, acute problems — glue ear, tonsils, a sports injury needing a specialist. It does not cover congenital conditions, chronic illness, or (usually) ADHD and autism assessments.
  • A newborn can normally be added without underwriting if you do it within the insurer’s window (often up to about 90 days).

What covering a child costs in 2026

RouteIndicative 2026 costWorth knowing
Add one child to an existing policy£10 – £30 / monthUsually the cheapest option; children are the least expensive people to insure
Add a second or third childOften £0 – £15 / monthMany insurers price on the eldest child; extra children can be free or heavily discounted
Standalone child-only policy£30 – £70+ / monthUseful for grandparents or a single parent whose work scheme won’t extend; fewer insurers offer it
Newborn added within the windowVaries; sometimes free for a spellOften no medical underwriting if added inside the insurer’s deadline (commonly up to ~90 days)
Adding an outpatient limit or dentalExtra premiumBase plans cap or exclude outpatient work; kids’ claims are often outpatient, so this matters

Indicative UK ranges for orientation, not a quote — a child’s premium turns on the plan tier, your excess, the hospital list and where you live. What moves it most is the outpatient limit, because that is where most children’s claims land. Always price it against the family hub before deciding.

Where cover genuinely helps with children

Childhood illness is mostly short, sharp and self-resolving, and that is exactly the shape private cover handles well. The classic examples come up again and again: grommets for persistent glue ear, tonsils or adenoids that keep flaring, a broken wrist off the trampoline that needs an orthopaedic opinion rather than just a plaster. On the NHS these are real but non-urgent, so they queue — and a wait that is an inconvenience for an adult can mean a child missing months of school or sleep. Private cover buys you a faster referral and a choice of consultant for problems like these.

The other quiet benefit is speed of reassurance. A rapid outpatient appointment when something is worrying you — a lump, a limp, a rash that won’t settle — can get a child seen and, more often than not, sent home reassured within days rather than weeks. Some plans also include a remote GP service, which for a feverish toddler at 9pm is worth more than it looks on paper.

The exclusions parents get caught by

This is the part worth reading twice, because it is where expectations and reality part company. Private medical insurance covers new, acute conditions — something that comes on after the policy starts and can be treated and resolved. It is not designed for anything long-term or present from birth. So congenital conditions (a heart defect, a cleft palate, anything a baby is born with) and chronic conditions (asthma, type 1 diabetes, epilepsy — illnesses that are managed, not cured) sit outside almost every policy. Care for those stays with the NHS, which is built for exactly that ongoing job.

The one that surprises people most is neurodevelopmental assessment. ADHD and autism assessment and diagnosis are excluded by most mainstream policies, and where an insurer does contribute it is usually a partial nod under an outpatient mental-health limit, with the ongoing therapy and medication left out. Learning and behavioural difficulties are treated the same way. It varies genuinely from insurer to insurer and plan to plan, so if this is your reason for buying, read the wording before you pay and ask the question directly — do not assume. Our note on pre-existing conditions explains the related rule: anything a child was already known to have before the policy started is usually excluded too.

Newborns, child-only plans and the cheapest route

For a new baby, timing is the thing to get right. Most insurers let you add a newborn to a family policy without fresh medical underwriting if you do it inside their window — often up to around 90 days from birth, though it varies, so check yours. Add the baby promptly and any condition that shows up afterwards is treated as new; leave it late and you risk the insurer treating early problems as pre-existing. A few insurers also give the baby a short spell of free cover at the start. Do note that anything identified at or before birth is congenital, so it falls under the exclusion above whichever way you play it.

On structure, adding children to a parent’s existing policy is almost always cheaper than a standalone child-only plan, and it is the route most families take. Child-only cover earns its place in narrower cases — a grandparent wanting to fund a grandchild’s cover, or a parent whose workplace scheme won’t extend to dependants. If cost is the sticking point, a higher excess or a guided hospital list will pull the premium down more than dropping the children ever would. It is worth comparing the sums on the private health hub, and reading whether PMI is worth it before you commit, since for a healthy child the honest answer is often “only for the extras”.

Children’s health insurance: FAQs

As a rough guide, adding one child to an existing adult or family policy runs around £10–£30 a month in 2026, and often less for a second or third child because many insurers price on the eldest. These are indicative figures — your excess, the plan tier and your hospital list move the actual price, so treat any number as a starting point rather than a quote.
Yes, a handful of insurers offer standalone child-only cover, typically around £30–£70 or more a month. It suits particular situations — a grandparent paying for a grandchild, or a parent whose work scheme won’t cover dependants — but for most families, adding the child to an existing policy is cheaper and simpler.
Usually not, or only partly. Most mainstream policies exclude the assessment and diagnosis of ADHD and autism, treating them as long-term developmental conditions rather than acute illness. Where an insurer does help, it is often a limited contribution under an outpatient mental-health allowance, with ongoing therapy and medication excluded. It varies a lot, so check the specific wording and ask before you buy.
No. Conditions present from birth — congenital problems — sit outside standard private medical insurance, as do chronic conditions like asthma, epilepsy or type 1 diabetes. Private cover is for new, treatable problems that arise after the policy starts. The NHS remains the route for anything long-term or present at birth, and it is designed for exactly that.
Contact your insurer and add the baby within their window — often up to around 90 days from birth, though it varies. Doing it promptly usually means no fresh medical underwriting, and some insurers give the baby a short period of free cover. Just remember that anything identified at or before birth counts as congenital and stays excluded regardless of when you add them.
It depends what you want from it. For faster treatment of one-off problems — grommets, tonsils, an injury needing a specialist — and quick reassurance when something worries you, it can be genuinely useful and children are cheap to add. But it won’t touch chronic or congenital conditions, and healthy children rarely need much. Weigh the modest cost against how often you’d realistically use it.
Absolutely. Private cover sits alongside the NHS, it doesn’t replace it. Your child keeps full access to GPs, A&E, emergency and long-term care exactly as before. Private insurance simply gives you a faster, private route for the specific acute conditions it covers — you choose which to use case by case.
