What does family Private Medical Insurance cost in the UK in 2026?
Family Private Medical Insurance in the UK typically costs from around £110 a month for a young couple with one child on a core plan, up to £350 a month or more for an older family on comprehensive cover with a full outpatient limit. The premium is driven mainly by the age of the parents, not the number of children.
A useful benchmark to anchor to: Which? found that at age 30, comprehensive individual cover averages £55.92 a month and core cover averages £32.81 a month. Family policies apply a rough 10% discount over the equivalent separate policies, and most major insurers charge only for the eldest child when you add multiple under-20s.
That means a healthy couple in their early 30s with two young children, on a moderate cover level, will typically see quotes in the £110 to £160 a month range. The same family on comprehensive cover with full outpatient and enhanced mental health rises to £180 to £240 a month.
Once the parents move into their 40s and 50s, expect the range to shift up by 40% to 80%, because age is the single biggest driver of a PMI premium.
Those are ranges, not promises. Postcode, underwriting method, excess and hospital list all move the number. But if you are being quoted well outside those bands on similar cover, something is off with the quote.
How is a family PMI premium calculated?
Six factors do most of the work on a family PMI premium.
Age of each adult. Insurers price by age band, and the bands step up sharply from 50 onwards. A five-year age gap between two policies can move the premium 15% to 25% on its own.
Number and age of children. Most UK insurers, including Bupa and Aviva, charge for the eldest child only when you add multiple under-20s to the same policy. Children under age 20 are the same rate regardless of number after the first. Adult children (usually 18 to 25 in full-time education, depending on the insurer) are priced differently.
Postcode. UK PMI is priced by region. London and the South East run higher than the North West and Wales. That reflects the underlying cost of private hospital care in each area.
Level of cover. Core, moderate and comprehensive tiers each carry a different premium. The step from moderate to comprehensive is usually the biggest single lever the family controls.
Excess. A voluntary excess of £250 or £500 typically reduces the family premium by 10% to 20%. It only bites once per policy year per person, so on a family policy it is often better value than it looks.
Underwriting method. Moratorium or full medical underwriting. Moratorium is quicker, and any pre-existing condition falls out of exclusion after two symptom-free years on the policy. Full medical underwriting decides everything upfront.
Why do two families of the same size pay very different premiums?
Two families with the same number of people can get quotes that are £150 a month apart, on what looks like the same cover. That is usually driven by four things.
Age spread. A couple aged 32 and 34 pay meaningfully less than a couple aged 47 and 49, even before we get to the children. Age is doing most of the work.
Outpatient limit. Comprehensive plans offer either a very high outpatient cap (say £2,000 to £5,000 a year) or unlimited outpatient. Core plans might restrict outpatient to £500 or exclude it entirely. That single line item can be a third of the premium.
Mental health cover depth. Enhanced mental health cover for parents and, importantly, for children and teenagers has become a much more visible add-on since 2023. It is not always included by default. If it is, expect a 10% to 15% uplift.
Hospital list. Every insurer has multiple hospital lists at different prices. The cheapest list restricts you to a smaller network. A "guided care" or "open referral" model, where the insurer helps you choose the consultant, is usually offered at a discount over full hospital choice.
How does adding a child to a policy change the cost?
Adding your first child to a couple's PMI policy typically adds £20 to £45 a month on a moderate plan. Adding a second, third or fourth child under age 20 adds nothing on the major insurers that price on the eldest child only.
Newborns get preferential treatment: Bupa and Aviva both offer free cover for the first three months from birth, which is worth adding the baby to the policy early to lock in cover for their medical history from day one.
Children remain covered on the family policy until age 18, or in full-time education up to age 21 or 25 depending on the insurer, then need their own policy.
How much can you save by choosing a higher excess or fewer add-ons?
Two levers usually make the biggest difference for a family that wants to bring the premium down without gutting the cover.
Excess of £250 or £500. On a family plan, an excess only applies once per person per policy year. A £250 excess on a family of four is a maximum annual exposure of £1,000, and it typically cuts the monthly premium by 10% to 20%. If your household would comfortably absorb that in a claim year, it is often the best value line item on the policy.
Drop discretionary add-ons. Dental, optical and complementary therapy add-ons are useful but often not the reason people take out PMI. Removing them can shave 8% to 15% off the premium. Some families keep dental and drop the rest.
Is it cheaper to insure the family together or separately?
Almost always cheaper together. A family policy is typically around 10% less than the same cover bought as separate individual policies, and the eldest-child pricing on multiple under-20s makes the gap wider for larger families.
Separate policies do make sense in a few specific cases: where two adults want very different levels of cover, where one adult has an existing policy with earned continuity they do not want to lose, or where a couple is not married or cohabiting and one insurer will not include them on the same policy.
How does the age of the parents affect the family premium?
Age is the single biggest driver. As a very rough guide from the Which? benchmark and our own experience, comprehensive family premiums increase by roughly 40% between a couple in their early 30s and a couple in their mid-40s, and by another 30% to 50% between mid-40s and mid-50s. Postcode and cover level matter, but not as much as the age band the two adults sit in.
That is why timing matters. Starting a family policy at 32 rather than 42 is a different premium for the entire life of the policy.
