Two adults, two children, and one question: how much does health insurance cost for a family of 4, and is it worth covering all four of you? This page is written for the parent doing that sum. It gives you an honest indicative range straight away, then spends most of its length on what moves a family of four's premium inside that range, because the range is wide and your own figure sits at one specific point in it. A broker can price that point for your four across several insurers in a single conversation, and the introduction costs you nothing; to reach one, fill in the form on this page.
It is not the side-by-side reading of policy wording; that lives on the excess page and the benefit-limits page, and the general family question is on what family health insurance costs. Where those quote a clause in full, this page says what it means for four people and sends you there.
How much is health insurance for a family of 4? An indicative range, and why it is a range
As a rough indicative range only, not a quote and not a price anyone has offered you: private medical insurance for two adults in their thirties or forties plus two children tends to land somewhere between about £1,200 and £2,400 a year, which is £100 to £200 a month, and parents older than that, or a policy with everything left in, can sit above the top of it. The exact figure for your family comes from a quote priced on the ages of all four of you, your health history and the options you choose, and that quote is what the broker reached through the form on this page gives you, without charge.
Nobody should read the bottom of that range as the likely answer. A family-of-four premium near the bottom of it is a policy with a great deal taken out of it: a high excess, a reduced or removed out-patient limit, a narrow hospital list and two young parents. The top end is the opposite on every setting, and choosing between them is what the rest of this page is about.
Quotes usually arrive by the month; this page leads on the annual figure on purpose, because the excess and the benefit limits that set it are counted per policy year, and a monthly price hides that. Compare two quotes on the annual figure and on what each has set those to.
Four people, four inputs: what a family of four's premium is built from
UK private medical insurance is priced on the people being covered, so a family of four is four sets of inputs on one application. They do not all weigh the same.
- The two adults' ages. In an age-rated market this is usually the largest input, and it keeps moving: each adult is a year older at every renewal. If there is a gap of several years between you, expect the older adult to account for more of the premium, and ask for the figure to be shown per person so you can see it.
- The two children's ages. We hold no insurer's child pricing, so this page will not tell you what a child adds; a quote will. What a family should ask instead is when each child stops counting as a child on the policy, because the age at which that happens, and what the policy does with them afterwards, is set by the wording. That question is covered on the age limits page for children on private health insurance.
- Health history, times four. Every member is underwritten, on a moratorium or on a full medical history, and a condition any one of you already has usually decides which. If any of you has something in the record, read how insurers treat pre-existing conditions before you ask for a price, because the price is not the whole of what changes.
- Where you live. Hospital lists are drawn by area, and a quote on a list without a hospital you could reach with two children in tow is not a quote for your family. How the lists work is set out on the hospital-list page.
- The settings you choose. Your three levers are the out-patient limit, the excess and the hospital list; the next two sections take the first two, because each behaves differently for four people than for one.
Before you ask anyone for a figure, decide which of those levers you are willing to move and which you are not.
The excess for a family of four: one choice on the quote, applied per member
An excess is the slice of each claim you pay yourself, and choosing a higher one lowers the premium. For one person that is a simple trade. For four it is not, because of how the wordings we hold count it. Aviva's Healthier Solutions terms and conditions (April 2025 issue, page 11, read 4 September 2026) list six excess options from £100 to £5,000 and make that excess payable, in the document's words, "for each member every policy year"; the full wording is set out on the excess page, which is where the comparison across insurers belongs. The phrase that matters here is "for each member". A £500 excess chosen to bring a family-of-four premium down is not one £500: in a year in which all four of you claim, it is four of them.
The other wordings we hold shape the same choice in different ways. Bupa's By You policy guide (BINS 14718, 2024, page 10, read 4 September 2026) works through a member who pays one excess on her first treatment and nothing further on later treatment in the same policy year, so the excess is a once-a-year event per person rather than a per-claim one. Freedom's Elite policyholder's guide to cover (April 2025, page 31, read 4 September 2026) takes the excess off the first valid invoice and any that follow until it is used up, and the member then pays that amount to the provider rather than to Freedom. WPA's Complete Health product information document (November 2025, page 2, read 4 September 2026) offers a choice: an excess per policy year, or Shared Responsibility, a co-payment in which 25% of each eligible claim is the member's, up to a level the member has picked. For a family that expects four separate small claims rather than one large one, a percentage share and a flat excess are different shapes of risk, and which suits you is a question for the quote, not for this page.
Three further points from the Aviva wording bear on a family directly. A claim that costs no more than the excess is yours in full: Aviva's worked example (page 12) has a member with a £1,000 excess and £1,000 of treatment meeting the whole cost. Treatment that runs on into the next policy year attracts the excess again (page 12), which matters when a child's course of treatment straddles your renewal date. And the excess sits on top of a benefit limit rather than inside it: Aviva's example (page 12) has a member with a £200 excess and a £500 limit paying the £200 and then being covered for up to a further £500. Those clauses are quoted in full on how much excess to choose and the yearly cost of private health insurance.
One route under the Bupa wording sidesteps the excess: a phone or video assessment through Direct Access is excess-free and leaves the out-patient allowance untouched (By You guide, page 7). A family likely to start a child's claim with a phone assessment should know that before the excess level is chosen.
The out-patient limit: the setting a cheaper family quote has usually moved
Out-patient cover pays for the consultations, tests and scans around a hospital stay, which is where most of a family's contact with private medicine happens. Reducing the limit is one of the quickest ways to bring a family-of-four premium down, and the wordings we hold show what goes with it.
Aviva's terms set a combined out-patient limit of £500 or £1,000, counted for each member every policy year, over a group of benefits the extract we hold does not name (April 2025 issue, page 7). Choosing that reduced limit has a consequence a family may not expect: two things then drop out of cover in every setting, in-patient, day-patient and out-patient alike. One is complications of pregnancy and childbirth; the other is tooth surgery done in a hospital (page 8). A family of four that might become five, or whose children's teeth may one day need a hospital rather than a dentist's chair, is buying a cheaper policy that has removed two things it might reasonably have wanted. The full clause is on benefit limits explained, and children's dental cover has its own page.
Aviva's cheapest out-patient option goes further. On the reduced out-patient cover £0 limit, nothing out-patient is covered, consultations and diagnostic tests included (page 24), though some of Aviva's networks are carved out of that £0 limit (page 8) and the extract does not say which. WPA's product information document gives specialist out-patient consultations a standard ceiling of £250 per policy year, which its Extra Out-patient Consultations option lifts (November 2025, page 1). Bupa's Direct Access assessment, mentioned above, takes nothing from the out-patient allowance (page 7).
For four people the per-member point from the excess section applies again: a limit written "for each member" is four separate pots, not one shared one, and whether a given policy shares or separates them is the question the family cost page takes up in full. The order of asking matters: ask which out-patient limit the quote is on, then what choosing it removed, and only then what it saved, because the second answer decides whether the third is worth having.
What the insurers' own wording settles for a family of four, and what it leaves open
Every row below is summarised in our words; the page in the last column carries the clause in full.
| Insurer and document | What the clause settles | What it leaves a family to ask | Quoted in full on |
|---|---|---|---|
| Aviva, Healthier Solutions terms and conditions, April 2025 issue, pages 7, 8, 11, 12 and 24 | Six excess options, £100 up to £5,000, each counted per member and per policy year; the excess applies again if treatment crosses into a new policy year; a £50 excess each on routine dental and optical; a combined out-patient limit of £500 or £1,000 per member; the reduced limit removes pregnancy-complication and hospital tooth-surgery cover; a £0 option removes out-patient cover altogether, with some networks excepted | Which benefits sit under the combined limit, which networks the £0 exception reaches, and whether the current March 2026 issue of the document, which we have not checked, changes any of this | Excess explained, Benefit limits explained |
| Bupa, By You policy guide, 2024, pages 7 and 10 | One excess per person per policy year, not per claim; a phone or video assessment via Direct Access: no excess, and nothing taken from the out-patient allowance | What the excess options and out-patient allowance are on the specific By You policy you are quoted, which the guide's examples do not set | Excess explained |
| Freedom Health Insurance, Elite policyholder's guide, April 2025, page 31 | The excess comes off the first valid invoice and later ones until used up, and is then paid by the member to the provider | Whether that is per member or per policy for a family; the clause we hold does not say | Excess explained |
| WPA, Complete Health product information document, November 2025, pages 1 and 2 | An excess per policy year, or a Shared Responsibility co-payment of 25% of eligible claims up to a chosen level; specialist out-patient consultations capped at £250 a year as standard, extendable | How Shared Responsibility is applied across four members, and the price of the extra consultations option | WPA: what it costs, Benefit limits explained |
Two cautions. The Aviva clauses are the April 2025 issue; a March 2026 issue has since appeared on Aviva's site and we have not re-checked these clauses against it, so treat them as the wording at that date and confirm against the current terms. And the table is an extract of four documents, not a survey: an insurer absent from it has not been found to lack anything, it was simply not in the material this page was built from, and all four were read on 4 September 2026. Take the third column to whichever quote you are looking at and get each answer in writing before the policy starts.
What to ask before you compare two family-of-four quotes
Two quotes for the same four people can differ by a wide margin and both be correct, because they are for different policies. These questions turn a pair of figures into a comparison.
- Is the premium shown per person as well as in total, so that you can see how much each adult and each child accounts for?
- Is the excess per member or per policy, and does it start again each policy year?
- Is a co-payment offered instead of an excess, and at what level?
- Which out-patient limit is the quote on, and what cover did choosing that limit remove?
- Is each benefit limit held per member or shared across the family?
- Which hospital list is it on, and which hospitals near you are on that list?
- How was each of the four of you underwritten, and does any member carry a special condition or exclusion the others do not?
- What happens to each child's cover and price when they reach the policy's child age limit?
- If you are self-employed and would pay through the business, what is the tax position for you and for the family? The tax page covers the benefit-in-kind side.
A broker can put all nine of those to several insurers at once and bring back the answers alongside the prices, which is a different thing from bringing back the prices alone. The form on this page reaches an FCA-authorised one; the request takes a few minutes and there is no charge for it.
Questions parents ask about a family of four's premium
How much is private health insurance for a family of 4?
Indicatively, and only as a broad market range rather than a quote, somewhere between about £1,200 and £2,400 a year for two adults in their thirties or forties plus two children, with older parents or fuller cover able to exceed that. Your exact figure is set by your four ages, your health history and your choice of excess, limits and hospital list, and it is a broker's or an insurer's to give, not this page's.
How much should health insurance cost for a family of 4?
There is no right figure, only a right figure for a given set of settings. The honest way to judge a quote is to find out what excess, out-patient limit and hospital list it is built on and compare it with another quote on the same settings. A quote that looks expensive may simply have left more cover in.
What does good health insurance for a family of 4 cost?
"Good" and "full coverage" in a search usually mean a low excess, full out-patient cover and a wide hospital list, and that combination sits towards the top of the indicative range above rather than the bottom. Ask what a comprehensive quote still leaves out, and get the exclusions and any special conditions in writing: on the wording we hold, a reduced out-patient limit alone removes two kinds of treatment from cover altogether, so "full" is a word to check rather than to trust.
What does health insurance cost for a family of 4 who are self-employed?
The price inputs are the same: four ages, four health histories and the settings you choose. What differs is who pays and how it is taxed, which depends on whether the policy is held personally or through a business; the self-employed cost page and the tax page cover that.
Why do US health insurance costs for a family of 4 look so different?
Because it is a different product in a different system. UK private medical insurance sits alongside the NHS, which remains the route for emergencies, GP care and long-term conditions, so the UK premium is buying a narrower thing than a US family plan does. A US figure is no guide to what a UK family of four will pay.
Will the cost go up as the children get older?
Expect the premium to move at every renewal, because every member is a year older, and expect a step change when a child passes the policy's child age limit. The renewal-price page explains the first; the age limits page explains the second.
What is the cheapest way to insure a family of four?
A cheaper family quote has usually moved one or more of the same levers: a higher excess, a lower or removed out-patient limit, a narrower hospital list. Each takes something out, and the sections above say what. There is more on those trade-offs on the page on the cheapest cover for a family of four.
If you have read this far you know which levers you are willing to move. A quote priced on exactly those is what the form on this page asks for; a broker comes back with a figure for your four, and the answers to the questions above beside it.
