- The age at which a person stops counting as a child is set by the policy, not by law, and it varies. Coverwise defines a child as aged under 18, or under 23 if in full-time further education.
- Monzo Max Family, underwritten by Zurich Insurance Company Ltd, covers financially dependent, unmarried children aged 19 or under at the start of a trip, or 21 or under if still in full-time education.
- On many annual family policies a child must travel with an insured adult to be covered, so an unaccompanied school or grandparent trip can fall outside the policy.
- The Association of British Insurers reported members paid 472 million pounds across more than 500,000 travel claims in 2024, with medical claims of 262 million pounds and an average medical claim of 1,528 pounds.
Cover for children rarely works the way parents expect. "Free child places" appear in marketing, but whether a particular child qualifies depends on three policy definitions that differ between insurers: the age at which a person stops being treated as a child, whether full-time education extends that age, and whether the child must travel alongside an insured adult. This guide sets out how those rules work, using the published definitions of named UK providers, so that a family policy can be matched to the children it actually needs to cover.
How child cover differs from adult cover
On a standard family or single-parent family policy, children are not separately rated in the way adults are. Coverwise, for example, defines a family as "two adults and any number of their children, stepchildren or foster children," and a single-parent family as "one adult" with the same children. The headline price covers the named adults, and qualifying children are added without a per-child charge. That is the mechanism behind the "free child" framing: the children are not free in isolation, but they are not individually priced on top of the adult premium.
The trade-off is that the definition of a child becomes the gatekeeper. A person who falls outside the policy's age band, or who is no longer financially dependent, is not a child for cover purposes and would need their own policy. Two children of the same age can therefore be treated differently by two insurers, because each insurer writes its own definition.
Dependent age limits, and why they vary
There is no single statutory age that insurers must use, so the cut-off is a commercial choice recorded in the policy wording. The pattern across the market is an upper age for any dependent child, plus a higher age that applies only while the child remains in full-time education.
Coverwise states that children covered under its family policies must be "aged under 18 (or aged under 23 if in full-time further education)." Monzo Max Family, by contrast, defines an eligible child as "financially dependant, unmarried (or not living with their partner) children aged 19 years old or under at the start of a trip (or aged 21 years old or under at the start of a trip if still in full time education)." Both use the same two-tier structure, but the numbers differ: Coverwise runs to under 18 then under 23, while Monzo Max Family runs to 19 then 21. For a 20-year-old undergraduate, that distinction decides whether the child is covered at all.
Three conditions tend to sit alongside the age limit and are easy to miss. The child usually must be financially dependent on the insured adult, must be unmarried (and, on the Monzo wording, not living with a partner), and the education extension generally requires the course to be full-time. A child who has started work, married, or moved onto a part-time course can drop out of the definition even while still under the headline age.
Cover limits and exclusions to check
The cover a child receives is the cover written into the family policy, so the same limits and exclusions that apply to adults apply to them. Emergency medical and repatriation is the figure that matters most: the ABI reported that medical claims reached 262 million pounds in 2024 and made up 34 per cent of all travel claims, up from 29 per cent in 2023, with one member paying over 1 million pounds for a single United States hospitalisation and repatriation. A child's medical event abroad draws on the same medical limit as the rest of the family.
Several structural points are worth confirming in the wording before relying on a policy for children:
- Accompanied travel. Many annual family policies require a child to travel with an insured adult. A child travelling unaccompanied, for example on a school trip or with grandparents, may not be covered unless the policy specifically allows it.
- Trip duration caps. Annual multi-trip policies cap the length of each trip. Monzo Max Family covers unlimited trips of under 45 consecutive days each, so a longer stay would fall outside the per-trip limit for every insured person, children included.
- Activities. The Foreign, Commonwealth and Development Office notes that some activities need specialist insurance or an add-on. Winter sports and certain adventure activities a child takes part in may require a separate section or upgrade.
- Pre-existing conditions. The FCDO warns that failing to declare existing conditions or pending treatment may invalidate the insurance. A child's medical history must be declared in the same way as an adult's.
Providers offering family cover with defined child rules
Only providers whose published child definitions could be confirmed are named here. The point is not which is cheapest, but how each draws the boundary of childhood, because that is what determines eligibility.
Coverwise sells annual and single-trip cover as an independent intermediary. Policies are underwritten by Inter Partner Assistance S.A., part of the AXA group, which is authorised by the Prudential Regulation Authority under firm reference 202664. Its family and single-parent family definitions cover any number of the adults' children, stepchildren or foster children aged under 18, or under 23 in full-time further education.
Monzo Max Family is a packaged bank account benefit rather than a standalone policy bought direct. The travel insurance is underwritten by Zurich Insurance Company Ltd, with claims handled through Qover's portal inside the Monzo app. The base Monzo Max plan starts from 17 pounds a month and is an individual plan; family members are added at 5 pounds a month each, must be named on the policy, and qualifying children are covered up to 19, or 21 in full-time education. The cover applies to members aged 18 to 69 and uses a 45-day per-trip cap.
Staysure offers a dedicated family travel insurance product with cancellation cover up to 15,000 pounds. It is arranged by TICORP Limited (Gibraltar Financial Services Commission reference 663617) and administered by Howserv Limited (FCA reference 599282). Staysure has no upper age limit on the adult policyholder and states it can cover more than 1,300 medical conditions, which is relevant for families where an adult, rather than the child, carries the medical history. The specific child age band is set at the quote stage rather than stated on the main product page, so it should be confirmed in the wording for the policy being bought.
Common pitfalls when insuring children
The most frequent mismatch is assuming a child is covered by virtue of being young. Eligibility turns on the written definition, and a child just over the age band, no longer financially dependent, or on a part-time course can sit outside it. Where a child is unaccompanied, the accompanied-travel requirement on many family policies is the second common gap, and it often surfaces only at the claim stage.
A further point concerns the relationship between travel insurance and the Global Health Insurance Card. The NHS describes the GHIC as free and valid for up to five years, covering medically necessary state healthcare in the EEA and some countries, but it does not cover repatriation, private treatment, or ski and mountain rescue, and is not a replacement for travel insurance. The FCDO adds that some insurers waive the medical excess where a GHIC is used. For a child, the practical reading is that a GHIC can reduce certain state-treatment costs but does not remove the need for a policy that covers the child by name and age.
Finally, the age definition should be checked at renewal, not only at first purchase. A child who qualified last year can age out during the policy year, and on annual cover the relevant test is usually the child's age at the start of each trip. Reading the current wording, rather than relying on last year's terms, is the way to confirm a child is still inside the definition.
