How do travel insurers define a family?

A family typically includes one or two adults who are partners (married, in a civil partnership, or cohabiting at the same address, regardless of gender), and their unmarried dependent children under the age of 18 (or under 21 or 23 if in full-time education, depending on the insurer) who live in the same household. Most policies also cover stepchildren, foster children, and adopted children. The precise definition varies by insurer, so it is essential to read your policy wording before purchasing.

How insurers define 'family'

What counts as a "family" policy?

Not all insurers offer a defined "family" policy tier. Some provide an explicit definition of "family" in the policy wording, typically two adults and their unmarried dependent children under 18 (or under 21 if in full-time education) living in the same household. These policies may also define "single parent family" and "couple" as distinct tiers with their own terms.

Other insurers do not define a fixed family unit at all. Instead, they simply cover the people named on the policy schedule, subject to eligibility rules. This means that what constitutes "your family" for the purposes of cover depends entirely on who you have added to the policy.

The practical effect is the same: only people named on the policy schedule (or, for family-tier policies, people who meet the definition) are covered. If you are travelling with friends or family members who are not named on the policy, they will not be covered and should purchase their own travel insurance. Most insurers state this explicitly.

Who counts as a 'partner'?

The adults in a family or couple policy are usually defined as the policyholder and their spouse, civil partner, or someone they live with in a domestic relationship at the same address. Most insurers require cohabitation, and some specify a minimum period (typically six months). Some policies use the phrase "regardless of gender," making clear that same-sex partnerships are included.

If you are not married and do not live at the same address as your partner, you are unlikely to qualify for a family or couple policy. You would typically need to purchase separate individual policies instead.

How are children defined?

Children are generally defined as unmarried dependants under 18 who live in the same household. Most policies extend this to children under 21 if they are in full-time education. Some insurers extend the age further, up to 23, for children in full-time further education, so it is worth checking the specific threshold if you have older children who are still studying.

Stepchildren, adopted children, and foster children are typically included. However, children who do not permanently live with you may not be covered under all policies. Check the specific wording if your family includes children who split their time between households.

Children travelling on a family policy must usually be accompanied by a named adult. Most policies also allow children to travel with a close friend or relative aged 24 or over, on school trips with teachers, or (in some cases) independently to stay with close relatives abroad. These conditions are typically set out in the eligibility section of the policy.

What are the age limits?

Age limits vary significantly between insurers and are one of the most important things to check. Upper age limits for adults typically fall somewhere between 65 and 85, depending on the insurer and the type of policy. Annual multi-trip policies tend to have lower age limits than single trip policies. At the lower end, some insurers cap annual multi-trip cover at 65; at the upper end, some allow single trip purchases up to age 85.

If you or your partner are close to or above common age thresholds (typically 65, 70, 75, 79, or 85), check your eligibility carefully. An age limit that applies at the point of purchase may not prevent cover continuing if you turn the relevant age during the policy period, but the rules differ by insurer.

What about the excess?

Most travel insurance policies apply the excess per person, per incident, per section. This means that if a family of four all claim for the same lost suitcase, the insurer could in principle charge four separate excesses. However, some insurers cap the total family excess, typically at twice the individual amount when multiple family members are claiming for the same incident. This is worth checking, as the difference between a capped and uncapped excess can be significant for families.

The Financial Ombudsman Service has said that it may not be fair to apply separate excesses for both parent and child when the claim relates to shared belongings (such as baby clothes in a parent's suitcase), although it may be reasonable for a child's own valuable item. Check whether your policy has a family excess cap, as this can make a meaningful difference to the amount you receive in a claim.

Reduced benefits for children

Most policies reduce certain benefit limits for children. The personal accident death benefit is typically capped at £1,000 for those under 16 or 18, compared with £10,000 to £30,000 for adults. Personal money limits are also commonly reduced for under-16s, often to £50 or £100 compared with £200 or more for adults.

These reduced limits are standard across the industry and are unlikely to be negotiable. They reflect the lower financial exposure associated with children, but they are worth being aware of.

How insurers define 'close relative'

The definition of "close relative" (sometimes called "immediate relative") matters most in the cancellation and curtailment sections of a policy. Most insurers allow you to cancel your trip and claim if a close relative becomes seriously ill, is injured, or dies. But who counts as a close relative varies.

Most policies provide an explicit list. A typical comprehensive definition includes: mother, father, sister, brother, wife, husband, civil partner, domestic partner, fiancé/fiancée, daughter, son, grandparent, grandchild, parent-in-law, son-in-law, daughter-in-law, sister-in-law, brother-in-law, step parent, step child, step sibling, aunt, uncle, niece, nephew, cousin, and legal guardian. Some insurers go further: AXA, for example, also includes anyone for whom you have power of attorney.

However, not all definitions are equally broad. Some policies limit "close relative" to your immediate household and direct family, omitting extended relations such as aunts, uncles, nieces, nephews, and cousins. Staysure's definition, for example, does not include aunts, uncles, nieces, nephews, or cousins. This means that if an aunt falls seriously ill and you need to cancel your trip, you may not be covered under a more narrowly defined policy.

One important outlier to watch for: not all policies provide an explicit list at all. Aviva, for example, uses the term "close relative" in its cancellation section but does not define it in its glossary. This kind of ambiguity could become a point of dispute, which is exactly the type of issue the FOS has addressed in past decisions, generally resolving unclear definitions in the consumer's favour.

If someone you consider a close family member is not listed in your policy's definition (for example, an unmarried partner's parent, or a close friend who is like family), you may not be covered for cancellation if something happens to them. Check the specific list carefully before purchasing.

What to look for in your own policy

The family definition. Check whether your policy has a defined "family" tier or whether it simply covers named individuals. If it has a family tier, check the age limits for children, whether stepchildren and foster children are included, and whether children must live with you.

The close relative definition. Check the specific list of who qualifies. If it is vague or absent, be aware that this could become a point of dispute if you need to cancel.

The excess structure. Check whether the excess is per person or whether there is a family cap. For families with young children, a per-person excess on shared belongings can significantly reduce the claim payout.

Age limits. Check the upper age limit for purchasing the policy and for each policy type (single trip vs annual multi-trip). These vary widely between insurers.

Children travelling independently. If your children will travel without you at any point (on school trips, with grandparents, or to stay with relatives abroad), check whether the policy covers them in these circumstances.

Non-standard families. If your family situation is non-standard, such as a blended family, children living elsewhere, extended relatives, or unmarried partners at separate addresses, call the insurer directly before purchasing. A group policy may be more appropriate than a family policy.

The Financial Ombudsman Service (FOS) interpretation of 'family' in travel insurance

The Financial Ombudsman Service (FOS) is the UK's independent body for resolving disputes between consumers and financial services providers, including travel insurers. Its decisions are not binding legal precedents, but they provide important insight into how family-related terms are interpreted in practice.

Partners and age eligibility: insurers must be transparent

The definition of "partner" in a family policy is straightforward in most cases. Married couples, civil partners, and cohabiting partners living at the same address are generally included. However, problems arise when eligibility restrictions are not clearly communicated.

In decision DRN-4340006, an elderly couple's travel insurance through a packaged bank account failed to disclose that Mr Y was ineligible due to an age limit. The ombudsman upheld the complaint and ordered the bank to pay his share of the claim, as the couple would have purchased alternative cover had they been properly informed.

Takeaway: If you or your partner are close to or above common age thresholds (typically 65, 70, 75, 79, or 85 depending on the insurer), check the policy's eligibility criteria carefully. If a restriction was not clearly disclosed at the point of sale, the FOS may uphold a mis-sale complaint.

Children on family policies: excess and claims treatment

In its published guidance on policy excesses and limits, the FOS notes that children may or may not be named policyholders depending on the policy, but either way they are entitled to benefit when travelling with their parents. The FOS has said it may not be fair to apply separate excesses for both parent and child when the claim relates to shared belongings, such as baby clothes in a suitcase. However, it may be reasonable to apply a separate excess for a child's own valuable item, such as a tablet or phone.

Takeaway: Understand whether your children are named policyholders or simply beneficiaries under your policy. This affects how excesses, limits, and claims are applied. If the policy is not clear about this, the FOS will generally interpret it in the consumer's favour.

Mis-sale complaints: eligibility and the definition of family

The FOS's guidance on mis-sold travel insurance makes clear that it first checks whether the customer met the basic eligibility requirements, including age and residency. If a family member was ineligible (for example, a child exceeding the age limit or a partner not meeting the cohabitation requirement), and this was not made clear at the point of sale, the FOS is likely to uphold a mis-sale complaint.

Takeaway: Before purchasing a family policy, confirm that every family member you intend to cover meets the insurer's eligibility criteria. If you later discover a family member was ineligible and this was not made clear at the point of sale, you may have grounds for a complaint.

'Close relative': cancellation due to a family member's illness or death

A separate but related issue is the definition of "close relative" for the purposes of cancellation or curtailment cover. Most travel policies allow you to cancel your trip if a close relative becomes seriously ill or dies, but the definition of who counts varies between insurers and has been the subject of several FOS decisions.

In decision DRN-5449162, the insurer declined a cancellation claim following the worsening health of Mrs P's father, who had been diagnosed with metastatic cancer before the policy was purchased. The ombudsman did not uphold the complaint, finding that the pre-existing condition exclusion applied because the diagnosis pre-dated the policy. This highlights that even where a close relative's condition is covered by the definition, the pre-existing condition exclusion may still prevent a successful claim.

Where the definition of "close relative" is ambiguous or where pre-existing condition exclusions are applied to non-travelling relatives, the FOS tends to interpret the policy in the consumer's favour where the wording is unclear. The FOS expects insurers to have proper medical evidence before declining a claim on pre-existing condition grounds, rather than simply asserting a connection.

Takeaway: Check your policy's definition of "close relative" carefully. Most UK policies include parents, children, siblings, grandparents, in-laws, step-relations, domestic partners, and fiancé(e)s. If someone you consider a close family member is not listed, you may not be able to cancel with cover if they fall ill. Also be aware that even listed relatives' conditions may be excluded if they were pre-existing at the time of purchase.
