You have decided, or are close to deciding, to put a child on private medical cover: a baby who has just arrived, a child you want on your own policy, or a child covered on their own. What is settled at the point of buying is what the child is then held to: who counts as a child under the wording, where they have to live, how their medical history is treated, and how long the cover runs. This page sets out buying private medical insurance in the UK for children as the questions a parent is asked, in the order they arise, and quotes a clause wherever one we hold settles a step. If you want it priced for your own family, an FCA-authorised broker can take one set of details to several insurers; the form on this page sends your details to that broker, who will contact you at no charge.

There is no "good medical insurance for children" this site can name, because we do not recommend policies; there is such a thing as a good purchase, and it is one where those four terms are in writing before any money moves. This site is not the broker, either: we are not FCA-authorised, the one firm we introduce readers to does not cover the whole market, and we may be paid if you become its client.

Buying children's health insurance: the three ways a child ends up on a policy

To buy health insurance for children is to make one of three transactions, and which one you are making changes what you are asked.

  • Adding a child to a policy you already hold. The policy's underwriting basis, excess and hospital list are usually already set; what is open is whether this child qualifies as a child under the wording, from what date their cover runs and on what underwriting terms, and whether the premium changes the day the child goes on or at the next renewal. Ask the last before you say yes.
  • Taking out a new policy with the child on it. A family policy, or one in your name with the child as a member. Everything is open and the child's questions are answered alongside yours. The general sequence from quote to contract is on how to buy private health insurance; what follows here is the part of it that changes when a member is a child.
  • A policy for the child only. Searches for medical cover for a child only, or health insurance for my children only, ask whether a child can be a policy's sole member. We hold no wording describing one, which tells you about our reading and nothing about any insurer. If that is the cover you want, ask whether the insurer writes it, who the policyholder would be and who it deals with on a claim; for that question on its own, see child-only private health insurance.

One distinction runs under all three. The clauses we hold that name anyone speak of members, of children covered and of "you"; none speaks of a buyer. Holding a policy and being covered by it are separate roles, and for a child it is sharper, because someone other than the child is signing. "Can I buy health insurance for my child" is therefore two questions an insurer answers separately: can this child be a member of this policy, and can you be the person who holds it. Ask both.

When cover for a child can be arranged

Before birth, and a newborn. "Can I get health insurance for my unborn child" is asking whether a policy can be arranged for a baby who has not yet arrived. Nothing we hold describes cover for a child before birth, and we will not say whether any insurer offers it. What a parent can settle before the birth is what will matter afterwards: from what date a baby can be covered, whether there is a window after the birth, whether a baby born to a member goes on by notification or by application, and on what basis a newborn is underwritten. None of the five clauses behind this page answers those; the wordings that touch them are on what private health insurance for a baby costs, and for the timing, see private health insurance for a newborn baby.

An older child. A child of two, or seven, or fifteen may bring a medical history to the application, and how it is treated is the underwriting question taken up below. Whether a wording sets a lowest age for adding a child, which is what "health insurance for children under 10" is asking, we have not established for any insurer; private health insurance for children: age limits is the page for the age in, and the one age term this page holds is the age out.

For a year, or less. "1 year child health insurance" and "short term health insurance for child only" want a fixed term. Both of the clauses we hold that measure time at all measure it in policy years and periods of insurance, and neither describes anything shorter; whether any insurer sells a child cover for less than a year we have not established. Ask what happens at the end of the first policy year if you want it to run on.

What you are asked when you add a child, and what to have ready

The inputs for a child are the inputs for an adult — who is covered, where they live, how their medical history is handled, and the product choices — and getting a quote online walks through the general form. Two of those answers are tested against wording a child may not obviously fit.

Where the child lives

A residence box on a form stands in for a test in the contract, and the test can be exact. The Exeter's Health+ product summary makes UK residence two conditions, the legal right to live here and 180 days a policy year physically spent here (The Exeter, Private Medical Insurance — Insurance Product Information Document (Health+), October 2025, page 1, read 4 September 2026; an IPID is the regulatory summary, not the full wording, and getting a quote online carries the sentence in full). The clause is addressed to "you", and the question for a child is whether that reaches each member or only the policyholder: a child at school abroad, or with a parent in another country for part of each year, may sit differently against a 180-day test from the parent who signs. One insurer's term is not the market's; ask how yours counts a child's days.

How the child's medical history is treated

A form asks it as one field; what answers it is an underwriting route, and AXA Health's membership handbook names four of them (AXA Health, Personal Health membership handbook, October 2024, page 14, read 4 September 2026). Our copy came from an intermediary's document library rather than AXA's own site, and the four are quoted and worked through on do insurers cover pre-existing conditions?. The question a parent adds is whether a child joining an existing policy takes the route the policy was written on or is underwritten on one of their own, and from what date the child's cover is measured; neither is in the extract we hold. For a child with a condition on record, private health insurance with a pre-existing condition follows each route through, and nothing on this page is a comment on any condition.

What to have ready

Whether you go to an insurer, online or through a broker, these are what the questions above need from you:

  1. Each child's full name and date of birth, and whether they live with you for the whole year.
  2. For an existing policy, its number, the underwriting basis it was written on and the date it started; for a new one, the same details for each adult.
  3. The child's medical history, as far as the underwriting route asks for it: anything diagnosed, anything investigated, anything referred on, with dates.
  4. Your product choices, carried over or made afresh: excess, out-patient cover, hospitals, and whichever options the policy offers for a child.
  5. What you want in writing before money moves: from what date the child is covered, on which underwriting route, until what age, and what the premium does when the child goes on.

A broker can carry that list to several insurers in one conversation and bring the answers back beside the quotes. The form on this page passes that list on, and asking costs you nothing.

When does health insurance cut off for children?

The term these searches return to most often is the end: how long can a child stay on health insurance, and when does it run out. Each insurer sets it in its own contract, and the one such term we hold for this page is Freedom's, whose age limit for children covers a child "up to the end of the period of insurance during which they reach 25 years of age" (Freedom Health Insurance, Freedom Elite — Policyholder's Guide to Cover, under the heading "14.2 Age limits for children", dated 1 April 2025, page 42, read 4 September 2026, served from Freedom's own site; the clause is quoted in full on private health insurance for families — what it costs).

The limit is not an age but a date. A child who turns 25 part-way through a period of insurance is still a child under this wording until that period ends, so what a parent buys from Freedom for a child runs to a renewal date rather than to a birthday, and the two can be months apart. From any insurer, that converts into two things to have in writing: the age in its wording, and whether the birthday or the end of the policy year is what ends the cover.

Neither of the two ages that recur most in these searches comes from a wording we hold. "Health insurance for kids until 26" and "health insurance when child turns 18" both assume a cut-off no clause we hold sets: the Freedom wording above runs past 18, and what any other insurer sets we have not established. The age at which a child can be added is a different term again, and private health insurance for children: age limits takes both separately; for a child at university by then, see private health insurance for students, and for what a child can do once they age out, see private health insurance for young adults.

What the wording fixes on the day you buy: residence, and what counts as covered treatment

Two of the clauses we hold are terms a parent agrees to on a child's behalf without being asked about them. Both are Aviva's, from the April 2025 issue of its Healthier Solutions terms; Aviva has published a March 2026 issue since, which we have not read, so neither is offered as Aviva's current wording.

The first is what happens if a member stops living in the UK:

"If a member ceases to be a UK resident, we may cancel cover for that member from up to 14 days after we become aware, as the policy does not provide cover for any members who cease to be a UK resident and the relevant member will need to arrange alternative cover if they wish to continue their underwriting terms with another provider"

— Aviva, Healthier Solutions terms and conditions, April 2025 issue, page 31, read 4 September 2026.

Read for a child, three things are in it. Cancellation is for "that member", so one child moving abroad is dealt with as that child, and the clause says nothing about the rest of the household. It runs "from up to 14 days after we become aware", which puts the date in the insurer's hands once it knows, not on the day the child leaves; what you must tell Aviva, and by when, is not in the extract. And the last phrase contemplates a member continuing "their underwriting terms with another provider", so a child who leaves this policy may have something to carry to the next one, though whether another insurer would take a child on those terms is for it to say. If your family may move, a child may study abroad, or a parent may be posted overseas with the forces, ask each insurer how it defines a UK resident for a child, what notice it wants and what the child keeps; cover for a child living outside the UK is a different product, and international or expat cover is where that starts.

The second is shorter, and it sits behind every "does health insurance cover X for children" search:

"Treatment that is not eligible We do not pay for treatment that is not covered by your policy or the consequences of such treatment"

— Aviva, Healthier Solutions terms and conditions, April 2025 issue, page 26, read 4 September 2026.

For a parent buying, the point is where that sentence puts the work. What is covered is set on the day the policy is bought, by its benefit table, the underwriting outcome and the options chosen, and this clause then puts everything outside that, and anything that follows from it, beyond what Aviva pays. So whether a therapy, a dental treatment or a particular kind of appointment for a child is paid for is a question to settle before the policy starts, in writing, against the benefit table, not at the point of a claim. We hold no dental clause for this page, so for a child's dental cover, and whether orthodontics sits inside it, see private health insurance for children: dental cover; the questions below on speech therapy and on a long-term condition come back to the same benefit table.

Questions parents ask before they buy

Do children have to have health insurance in the UK?

Whether the law requires it is not something this page can answer: we hold insurers' policy wordings, not legislation, and we will not state a legal position we cannot cite. What the wordings describe is a product on sale: private health cover for children is cover an insurer will write and a parent chooses to pay for, buying a private route to the treatment the policy covers; whether that is worth the premium is your decision, and what the NHS covers for a child is the page to read before making it.

Are children covered under their parents' health insurance?

What you can check is the paperwork: a child is covered once the insurer has added them and the certificate or schedule says so, not by being yours. If a child's name is not there, treat them as not covered and ask. Children on your health insurance are the children named on it.

Does health insurance cover step-children and foster children?

Who can be added as a child is a definition in each insurer's wording, and none of the five clauses we hold supplies it; Freedom's age clause says who is too old, not who qualifies. So whether a step-child or a foster child can go on your policy is for each insurer to answer, and we have not established it for any of them. Ask in those words: can a step-child or a foster child be added, must they live at your address, and must the policyholder be a parent — which also settles whether a step-parent or a grandparent can hold or pay for it.

Can I cover a child after a divorce, or a child who lives with their other parent?

That turns on two things in the insurer's rules, and we have settled neither: whether a child at another address can be a member of your policy, and who the insurer deals with about the child's claims, the policyholder or the parent the child lives with. Health insurance for children after divorce turns on both, and private health insurance for children: support and service goes further on who holds the policy and who claims when parents live apart.

Can children buy health insurance for their parents?

The wordings we hold say who can be a member, not who can hold the policy, so whether an adult son or daughter can take out and pay for a policy over a parent is a question for each insurer. Ask whether you can be the policyholder for someone at another address and whether the parent is underwritten in their own right; how to buy private health insurance has more on buying for somebody else.

Does health insurance cover speech therapy for children?

No clause we hold names speech therapy, or any therapy, so we cannot say for any insurer. What we hold is Aviva's line that it does not pay for treatment the policy does not cover, which puts the answer in the benefit table of the policy you are offered: ask whether speech and language therapy is listed, under which heading, with what limit, and whether a referral is needed first. Nothing here is a view on whether a child needs it.

Can I get health insurance for a child with diabetes, or another long-term condition?

The name of a condition changes nothing on this page: what an insurer does with a condition a child already has is decided by the underwriting route and the exclusions in the wording, and the four routes in the AXA Health handbook above are where that starts. Ask which route the child would be on and what, in writing, would be excluded; for more, see private health insurance for a disabled child. None of this is a comment on the condition itself.

The next step is the application, and the questions on this page are the ones to settle before it: whether this child counts as a child under the wording, where they must live, which underwriting route they are on, and until when. Put them to the insurer yourself, or fill in the form on this page so an FCA-authorised broker can put them to several insurers for you alongside the quotes.
