Do insurers cover pre-existing conditions?

Usually not. Private health insurance in the UK is, as a rule, written to cover conditions that start after the policy does, and a condition you already have, which the wording calls pre-existing, is the one thing a new policy is most likely to exclude. That is not one insurer being awkward; it is how the product is built, and the three policy wordings we hold on the question all point the same way. So the decision you are really making is whether a policy that excludes the condition you have is still worth buying for the rest of your health, and on what terms the exclusion would be written. That second half is an underwriting question no website can answer, and it is what a broker is for: fill in the form on this page and an FCA-authorised broker can put your history to several insurers in one conversation. It is free and takes a few minutes.

This page gives the answer, explains why it is the answer, and quotes the three clauses. What to do about it already has its own page: how a moratorium differs from full medical underwriting, what each wording leaves open, and the questions to put to an insurer before you buy are all on our guide to private health insurance with a pre-existing condition, and this page sends you there rather than repeating it.

What this page answers

One question, directly: whether private health insurance companies cover pre-existing conditions. Then why the answer is what it is, and what three insurers' own documents say, quoted as they stand. It does not explain the underwriting routes, rank insurers or price anything; we hold no premium data and will not invent any. Private medical insurance, private health insurance and health cover are one product under three names, and the answer is the same for all of them.

Usually not, and that is the norm rather than one insurer

Of the three wordings we hold, the two that speak to the question directly, Bupa's and Freedom's, both exclude a condition you had before cover started unless the insurer agrees otherwise, and the third, AXA Health's, shows that how the condition is treated turns on the underwriting route the policy is set up under, not on which insurer you pick. None is a special case; these are standing terms of ordinary personal policies.

The reason is the shape of the product, and here we are generalising beyond the three documents. Insurance prices the chance that something will happen. A condition that has already happened is not a chance but a cost the insurer can see in advance, so a policy that took it on at an ordinary price would be paying from the first day for the thing it was bought for. Insurers deal with that by excluding the condition and covering what starts afterwards; on the wordings we hold the mechanism is exclusion of the condition, not refusal of the person. It is also why moving insurer does not get the condition covered: in general terms a new insurer underwrites you afresh, and reads the same history.

"Usually" is Bupa's word, and we have kept it because three things stop the answer being never. Freedom's clause leaves the door open to the insurer agreeing to cover a condition, on its terms. AXA's handbook lists "medical history disregarded" as one of four routes, a name that says what it does, and one which in general terms is more often found on a company scheme than offered to an individual. And a condition outside an insurer's look-back period may not be caught at all; Freedom's is five years, not for ever. Each of those is a question about a specific insurer and your specific dates.

What the policy wording says

Three clauses from three insurers' own documents, read on 4 September 2026. Each is one extract, not the document: it tells you what that clause says and nothing about what the rest of the document does.

Bupa: "aren't usually covered"

"Any conditions, special conditions, pre-existing conditions, moratorium conditions, conditions or symptoms, illnesses or injuries you had before your policy started aren't usually covered. If a special condition applies, we'll send a confirmation of special conditions to the main member"

— Bupa, Bupa By You policy guide (BINS 14718, 2024), page 11, read 4 September 2026.

The reach is the thing to notice: "symptoms" and "injuries" as well as diagnosed conditions, so something you saw a GP about but never had a name for can count, and so can an old injury. A "special condition" is a specific exclusion, confirmed to the main member in writing.

Freedom Health Insurance: five years, "or a related condition", unless agreed

"A pre-existing condition is a medical condition you had before your cover under this policy started. We will not cover a medical condition, or a related condition, you had within the five-year period before your cover with us started unless we have agreed to cover that condition."

— Freedom Health Insurance, Freedom Elite Policyholder's Guide to Cover (April 2025), page 8, read 4 September 2026.

The only definition of a pre-existing condition we hold, and the only clause that puts a number on the look-back. "Or a related condition" reaches whatever Freedom treats as connected to your diagnosis, and the extract does not define "related".

AXA Health: the route decides

"(full medical underwriting) Continuing medical exclusions Medical history disregarded Moratorium. In the following panels, we've explained how each of these work"

— AXA Health, Personal Health membership handbook (October 2024), page 14, read 4 September 2026. The copy we read is hosted in an intermediary's document library rather than on AXA's own site; the handbook that came with any policy is the one that binds.

A list of headings, but it establishes what the other two do not: on a single personal product, the treatment of a pre-existing condition depends on which of four routes the policy was set up under. The panels explaining each route are not in our extract, so this page does not say what AXA means by any of them.

Three wordings are three wordings. They agree that the condition you already have is excluded unless the insurer agrees otherwise, and we have not read a personal policy wording that says anything different; but we have read three, and where this page says "usually" it is generalising from them, not reporting a rule. What each one leaves open is set out gap by gap on the fuller page. A broker can put those gaps to several insurers as questions about your own history, and the form on this page is how to reach one; there is no charge for the conversation.

Common questions

What counts as a pre-existing medical condition for health insurance?

On Freedom's wording, "a medical condition you had before your cover under this policy started"; Bupa's reaches further, to symptoms, illnesses and injuries, so a problem you saw someone about without ever getting a diagnosis can count. The wordings differ in reach, which is why the definition in your own policy document is the one to read.

Can a health insurance company refuse me because of a pre-existing condition?

The wordings we hold describe excluding the condition, not turning the applicant away, and that is the usual outcome: you are accepted and the condition is written out. Whether a particular history would lead an insurer to decline cover altogether is an underwriting decision that cannot be read off a document, so being accepted with a pre-existing condition and being covered for it are different things, and it is the second that is rare.

Can an insurer charge more for a pre-existing condition instead of excluding it?

We hold no clause on it and no premium data, so we cannot say. On the three wordings we hold the mechanism is exclusion, and none describes pricing a pre-existing condition instead; whether a quote has been loaded, excluded or both for your history is something to have in writing before you accept it.

Does company or group health insurance cover pre-existing conditions?

Sometimes, and it depends on the basis the scheme was set up on rather than on its being a company scheme. AXA's handbook lists "medical history disregarded" as one of four routes, and in general terms that is the one under which a member's history is not used to exclude anything; we hold no group scheme wording, so ask the scheme's insurer which basis applies.

Is there a waiting period for pre-existing conditions?

The phrase "pre-existing waiting period" is common in searches, but none of the three UK wordings we hold uses it or describes a period after which a condition you already have comes into cover automatically. On Bupa's and Freedom's clauses the exclusion is tied to your history, not to a date; whether an exclusion can ever lift under a moratorium, and what being asked no medical questions actually means, is on the fuller page.

The answer to the question you searched is usually not, and it holds across the market as far as we have read it, so the useful next step is not to hunt for the insurer that says yes but to find out how each would write the exclusion for your history and what the policy would still cover. Fill in the form on this page and an FCA-authorised broker will call you back and put your dates to several insurers; take the questions from the fuller page with you. There is no obligation.
