Private health insurance for families in the UK

A family private medical insurance (PMI) policy covers two or more people — usually a couple and their children — under one plan. Each person is still priced on their own age and health, but a family plan can be simpler to run and children are usually the cheapest to add. Here is how family cover works and how to keep the premium down.

The essentials in 30 seconds

  • One plan, priced per person: a family policy bundles a partner and children together, but each person is rated on their own age and health — it is not a single flat household price.
  • Children are usually cheapest: child cover is typically the lowest-cost element of a family plan; older adults carry the highest individual cost.
  • What matters for kids: faster diagnostics and specialist referrals, in-patient and day-patient treatment, and on some plans outpatient and mental-health support.
  • Keep it down: raise the voluntary excess, choose a guided hospital list, trim optional modules, and check whether a shared or per-person excess suits your family.

What changes when you cover a family

AspectWhat it means for a family policy
Adding a partnerA second adult is priced on their own age and health; some insurers apply a small discount for covering more than one adult on the same plan
Adding childrenChildren are added individually but are usually the cheapest people to cover; many insurers let you add new children at renewal or after a birth
Cost of child coverOften the lowest-cost element of the plan, because younger lives generally make fewer high-cost claims
What is relevant for kidsFaster diagnostics and specialist referrals, in-patient and day-patient treatment, and on some plans outpatient and mental-health support
Family vs individual policiesA family plan groups several individual risks under one renewal date; separate policies keep each person independent but mean more admin
Shared vs per-person excessSome plans apply one shared excess per claim year for the whole family; others charge the excess per person who claims — this changes what you pay if more than one person claims

Indicative for orientation only — not a quote. How adults and children are rated, and how the excess applies, varies by insurer and the cover you choose.

How to keep a family premium down

Because every person on a family plan is priced individually, small design choices add up across the whole policy. The levers that matter most for families:

  • Voluntary excess: a higher excess lowers the premium, but check whether it applies once per year for the family or per person who claims — a per-person excess can add up if several family members claim in the same year.
  • Hospital list: a guided or regional list rather than a full central-London list can cut the premium noticeably while still giving good access to private facilities for the whole family.
  • Trim optional modules: dental and optical add-ons are convenient across a family but add cost on every person — keep the core in-patient and day-patient cover and add modules only where you will use them.
  • Six-week NHS-wait option: this only funds private treatment when the NHS wait is longer than six weeks, which keeps the premium below full immediate-access cover — a useful base for healthier families.

Which modules earn their place on a family plan

Optional modules are where family premiums grow fastest, because each add-on is applied across everyone on the policy. A few tend to be more useful for households with children:

  • Outpatient cover: funds consultations, diagnostics and scans before any admission — the part families with children tend to use most, since much of children’s care is investigation and referral rather than surgery.
  • Mental-health support: increasingly offered for both adults and children; worth checking the limits and whether children are included.
  • Dental and optical: convenient but priced per person, so they add up quickly on a family plan — only worth it if the family will use them regularly.

There is no single right answer: the value of each module depends on how your family is likely to use care. Compare the cover and the exclusions, not just the headline price, and review the plan at each renewal as the children grow.

Family private health insurance FAQs

A family policy covers two or more people — usually a couple and their children — under one plan with a single renewal date. Each person is still priced on their own age and health, so the premium reflects the mix of people on the policy rather than a flat household rate.
Children are usually the cheapest people to add to a family plan, because younger lives generally make fewer high-cost claims. They are still added individually, and many insurers let you add a new child at renewal or after a birth. The exact cost depends on the insurer and the cover chosen.
For children, the value is typically faster diagnostics and specialist referrals, plus in-patient and day-patient treatment. Some plans also include outpatient and mental-health support for children. Cover and limits vary by insurer, so check what is included for under-18s before you choose.
It depends. A family plan prices each person on their own age and health under one policy, with a single renewal and often a shared excess, and some insurers give a small multi-adult discount. Whether that beats separate policies comes down to the ages and health of the people involved, so it is worth comparing both.
A shared excess is paid once per claim year for the whole family, no matter who claims. A per-person excess is charged for each individual who claims in that year. If several family members are likely to claim, a shared excess can work out cheaper overall — always check which way the plan applies it.
Raise the voluntary excess to a level you could comfortably meet, choose a guided or regional hospital list, trim optional modules you will not use across the family, and consider a six-week NHS-wait option. Reviewing the plan at each renewal as the children grow also keeps the price in check.
Most insurers let you add a new partner or a newborn to an existing plan, often at renewal or within a set window after a birth. The new person is underwritten and priced on their own circumstances. Check your insurer’s rules on when and how additions can be made.
