Family Private Health Insurance UK: Costs and Cover Options

What a family policy actually is

A family private medical insurance policy is a single contract that lists more than one person as covered. The most common shape is two adults plus their dependent children, but most insurers also allow single-parent families and let you add or remove people as circumstances change. Administratively it is one renewal date, one premium and one set of documents, which is simpler than running separate adult policies.

Underneath that single wrapper, however, each adult is still risk-rated individually. The premium reflects the ages and, where full medical underwriting is used, the medical histories of the grown-ups on the plan. Children are usually added at a modest additional cost and sometimes free of charge up to a certain number on family plans, because as a group they tend to claim less and for less complex conditions.

It is important to separate what PMI does from what the NHS continues to do. A family policy does not turn the NHS off: emergency care, GP appointments, routine childhood vaccinations and chronic disease management remain available. The policy adds a private route for prompt diagnosis and treatment of acute conditions, with choice of consultant and hospital.

How children are covered

Children on a family plan are generally covered for the same acute conditions as adults, including consultations with specialists, diagnostic scans and inpatient or day-case treatment. Some insurers include enhanced child-specific benefits, such as access to a private GP or paediatric services, and a few waive the excess for children. The detail varies by insurer, so the children's section of the policy wording is worth reading carefully.

There are predictable exclusions. Routine developmental checks, standard vaccinations and the day-to-day care a GP provides are NHS services, not PMI claims. Congenital conditions present from birth are commonly excluded or restricted, and conditions a child was treated for before joining the policy are subject to the same pre-existing rules as for adults.

Mental health cover for children and adolescents is an area where policies differ widely. Where it is included it may be capped in sessions or pounds per year, and some plans exclude certain conditions entirely. If this matters to your household, check whether it is core cover or an add-on before relying on it.

How family cover is priced

Because each adult is risk-rated, a family premium is broadly the sum of individually assessed costs rather than a flat household rate. The biggest single drivers are the ages of the adults and the hospital list you select: a list that includes central London private hospitals costs more than a regional list. The excess you accept, and whether you add outpatient and mental health cover, then move the price up or down.

Children typically add proportionally little, which is why family cover can look better value per person than two separate adult policies plus child cover bought piecemeal. That said, the value depends entirely on the cover bought. A cheap plan with a high excess and no outpatient benefit may pay out far less than its price suggests when an early diagnosis is needed.

Premiums are recalculated at each annual renewal and generally rise with the age of the adults and with medical inflation. A no-claims-style discount or shared family excess can soften this on some plans, but the long-run trend is upward, so it is sensible to plan for the cost increasing each year.

Maternity, pregnancy and what is excluded

Family PMI is frequently bought by households planning to grow, so the maternity position is worth stating plainly. Routine pregnancy and childbirth are generally excluded from PMI, because uncomplicated maternity care is an NHS service. What policies more commonly cover are complications of pregnancy that are acute medical conditions, and some plans pay a small cash benefit per night of NHS maternity stay.

A newborn can usually be added to the family policy shortly after birth, but cover for the child begins from the date they are added and is subject to the standard pre-existing condition rules. That is one reason families review their cover around a birth rather than assuming a baby is automatically and immediately insured for everything.

Other typical exclusions across family plans include chronic condition management, cosmetic procedures, fertility treatment and pre-existing conditions. None of this is unique to family cover, but the breadth of people on the policy makes it more likely at least one exclusion will be relevant, so reviewing them as a household is worthwhile.

FCA rules and the protections you keep

Whoever arranges the policy must be authorised by the Financial Conduct Authority and follow ICOBS. The product documentation must be clear, fair and not misleading, and you must receive enough information to make an informed choice before buying. A new policy carries the ICOBS 7 cancellation right of at least 14 days, during which you can cancel for a refund subject to a deduction for any cover used.

Each adult answering medical questions has a duty under the Consumer Insurance (Disclosure and Representations) Act 2012 to take reasonable care not to misrepresent their history. Because a family plan involves more than one person's disclosures, it matters that every adult answers accurately: a careless or deliberate misrepresentation by one person can affect a claim relating to them.

If a claim for any family member is declined and you disagree, ask for the insurer's final response in writing and, if still dissatisfied, refer the matter free of charge to the Financial Ombudsman Service, usually within six months of that response.

Frequently asked questions

How many children can I add to a family policy?

This varies by insurer. Many family plans cover several dependent children, sometimes at no extra cost up to a set number, with additional children added for a modest premium. Check the insurer's family terms, as definitions of a dependent child and the upper age limit differ.

Does family health insurance cover pregnancy and birth?

Routine pregnancy and childbirth are generally excluded, because uncomplicated maternity care is an NHS service. Policies more often cover acute complications of pregnancy and sometimes pay a small cash benefit per night of NHS maternity stay. Read the maternity section before assuming cover.

Are children covered for the same things as adults?

Largely yes for acute conditions, and some plans add paediatric or private GP benefits. However, routine childhood vaccinations, developmental checks, congenital conditions and pre-existing conditions are commonly excluded, and child mental health cover can be capped or limited.

Is a family policy cheaper than separate policies?

It can be, because children usually add proportionally little and you manage one renewal. The value depends on the cover bought rather than the structure alone, so compare what each plan actually pays for, not just the headline price.

Can I add a newborn to the policy?

Usually yes, shortly after birth, but cover starts from the date the baby is added and is subject to the standard pre-existing condition rules. Families often review cover around a birth rather than assuming automatic full cover.

What if the insurer rejects a claim for my child?

Request the insurer's final response in writing. If you remain unhappy, you can refer the complaint free of charge to the Financial Ombudsman Service, generally within six months of the final response.
