If you have had treatment or support for your mental health in the past and are weighing up private medical insurance, the decision in front of you is narrower than "does this policy cover mental health". It is how the insurer will treat your history, and that is settled by the underwriting route behind the quote, not by the benefit table. An FCA-authorised broker can take your dates and your background to a number of insurers at once and tell you which route each quote rests on. That introduction is free to you; you can start it from this page's form.
Each insurer's wording below carries the issue and date it comes from. One clause shows what that clause says, not how the rest of the policy works with it, and none of it can tell you how your own history would be treated: that is the insurer's decision, made on your details.
This page is about the small print of insurance, nothing more. If you need someone to talk to now, Samaritans are on 116 123 around the clock at no cost, and Mind (mind.org.uk) offers information and support. You do not need a policy to use either.
A limit and a history are two different questions
A mental health benefit has a size: so many days in hospital, so many pounds of out-patient treatment. How the policy treats what has already happened to you is a separate rule, written elsewhere in the same document, and it is the rule that decides whether the size matters to you. The two are easy to blur, because search results mix them: someone who types "mental health insurance pre existing" is usually asking the second question and being shown pages about the first.
The comparison of benefits, insurer by insurer, is on comparing mental health cover, and the underwriting routes themselves are laid out on private health insurance underwriting explained. This page does the part in between: it takes the wording each insurer uses about past conditions and asks what a reader with a mental health history should notice in it, what to tell the insurer, and what to ask.
How the wording on past conditions reads when your history is mental health
Of the past-condition wording below, Vitality's is the one that names mental health directly. The rest are general look-backs and written-disclosure rules, which reach a mental health history in the same way as any other.
Vitality: the clause that names mental health
Vitality's Membership Guide (Your Personal Healthcare plan terms and conditions, August 2024, page 30, read 10 October 2026, in a copy hosted by a broker rather than Vitality) says that "Medical and mental health conditions (and related conditions) you currently have or had in the past, that are likely to need treatment in the future, are not covered". Read it as a description of the wording, not a verdict on anyone's history. Its reach depends on two phrases it does not define, "related conditions" and "likely to need treatment in the future", and who judges that likelihood, and how, is worth putting to Vitality, or to the broker when they phone you back, free, after the form. Our comparison of mental health cover takes the clause phrase by phrase; what matters here is that it sits beside two other passages in the same guide.
Page 48 makes awareness the test for the moratorium's look-back, excluding conditions "you were aware of during the five years before your cover began, even if you have not needed to see a GP about them". For a history that includes things never raised with a doctor, such as a low period managed alone, the clause is not limited to a diagnosis on a record. Page 30 also describes a way back in, once there has been no "treatment, advice or medication for that condition for a continuous period of two years after taking out your plan", and it lists "Pre-existing medical conditions that we permanently exclude from your cover" without saying which. "Advice" sits beside treatment and medication, so whether a counselling session or a check-in call counts as advice is a question to put to Vitality in writing. How the mental health clause fits with either passage is part of the same question. How they work together as a moratorium is set out on Vitality health insurance: underwriting.
The other insurers' wording below is general and does not name mental health; that makes it neither harsher nor kinder to a mental health history, and how each applies it to yours is the insurer's decision.
A look-back without the word moratorium
Freedom Health Insurance also reaches back five years, but defines the exclusion rather than naming a moratorium. Its Freedom Elite Policyholder's Guide to Cover (April 2025, page 8, read 4 September 2026) excludes "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". "Related condition" is not defined in the clause, and "unless we have agreed" makes Freedom's agreement the thing to find out about.
Telling the insurer in writing
Aviva's Healthier Solutions terms and conditions (April 2025 issue, page 27 of the PDF, read 4 September 2026) ties the position to what you said on the application: pre-existing conditions are not covered, or related ones, "unless you advised us of that condition in writing when you applied for the policy and either we did not apply an exclusion for it, or it is not excluded under the policy". Two conditions have to be met, and the first is yours. A newer Aviva issue, dated March 2026, has since been published, so check this wording against the issue that comes with your quote.
Bupa's Bupa By You policy guide (BINS 14718, 2024, page 11, read 4 September 2026) lists "conditions or symptoms, illnesses or injuries you had before your policy started" among the things that "aren't usually covered", and says that where a special condition applies, "we'll send a confirmation of special conditions to the main member". The word "symptoms" widens the net beyond a named diagnosis, and the confirmation means the terms can be seen in writing. Which underwriting route produces either outcome is a question to ask alongside the quote.
For mental health the same guide has no "usually". Its mental health benefit opens with a flat exclusion:
"Mental health treatment for or related to special conditions, pre-existing conditions and moratorium conditions isn’t covered. Mental health treatment related to anything else in the ‘What isn’t covered’ section is covered as set out in this benefit."
— Bupa, Bupa By You policy guide (BINS 14718, 2024), page 20, read 4 September 2026.
The guide's list of exclusions repeats the point on page 27. So at Bupa, a mental health condition that counts as pre-existing or as a moratorium condition sits outside the mental health benefit.
Four routes at one insurer
AXA Health's Personal Health membership handbook (October 2024, page 14 of the PDF, read 4 September 2026, in an intermediary-hosted copy) lists four underwriting routes, from full medical underwriting to moratorium. How each works is set out in the handbook itself; the list alone shows that at AXA Health the treatment of your past turns on the route chosen, so the route behind a quote is worth knowing before its price. Our page on how insurers treat pre-existing conditions sets the general wordings side by side.
What the benefit clauses leave out about history
Mental health benefit rows describe what is paid, and apart from Bupa's, quoted above, the ones compared here do not speak to a past condition. That is not a criticism; a benefit table is not the place for it. Aviva's April 2025 terms, for instance, show "Up to £2,000" for out-patient mental health treatment on page 6 and "In full up to 28 days" of in-patient and day-patient accommodation and nursing on page 10, and neither row says anything about a condition you had before you joined. The rows from Saga, WPA, AXA Health, The Exeter and Bupa are set side by side on the comparison page.
The point for you is what those rows do not answer: what happens when the condition you want treated is the one you had before the policy started, or what an exclusion written at underwriting does to a benefit shown in the table. A limit and an exclusion can both be on the same policy. So when you compare mental health quotes, the benefit line and the underwriting line need to be read together, and a broker can set out both, for each insurer, on the same page of questions.
What to tell the insurer, and how to prepare
This is about the application, not about your health, and it is not medical advice. The wording above suggests four practical habits.
- Answer what is asked, in writing. Aviva's clause hangs on what you advised "in writing when you applied". In general, you are expected to take reasonable care in answering an insurer's questions, and a wrong answer given carelessly can cause problems at claim time; a broker can explain how the questions on a given form work.
- Write down your dates before you start. When something began, the last appointment, the last prescription and anything such as a workplace counselling referral. The five-year look-backs and Vitality's two-year clear period are only usable if you can say when things happened.
- Do not assume that the absence of a diagnosis helps. Vitality's page 48 wording is about awareness, and Bupa's lists symptoms. If you are unsure whether something counts, ask rather than leave it out.
- Keep every reply. Ask for the route, the look-back and any special condition in writing, and file it with the policy papers.
Talking to a broker is not a commitment to buy. Describing your background once, with dates, means the same facts reach each insurer, and a short call is all it takes to begin.
Questions to ask before you choose a policy
Take these to the insurer or to a broker, in this order, because the early ones change what the later answers mean:
- Which underwriting route is this quote built on, and which others are available on the same policy?
- If it is a moratorium: how many years does it look back, does "aware" or "advice" cover things I never took to a GP, and can a routine appointment break the clear spell?
- On full medical underwriting: will I see the terms in writing before I pay, and what will you ask beyond my own answers?
- How does the wording treat a "related" condition, and who decides what is related?
- Is there any category of past condition that is permanently excluded, and where is it described?
- Is mental health on the certificate, and what out-patient and in-patient limits apply once any exclusion is applied?
- Which printed issue of the terms governs my policy? (Aviva, for one, has published a March 2026 issue after the April 2025 one.)
Short answers
Does private medical insurance cover existing conditions?
The general wordings from Bupa, Freedom and Aviva quoted above each treat a condition you had before the policy as outside cover unless an exception applies: Bupa says such conditions "aren't usually covered" (and, for mental health treatment, that they aren't covered), Freedom excludes them "unless we have agreed to cover that condition", and Aviva ties the position to written disclosure at application. Whether a particular history falls inside or outside is the insurer's decision on your own details.
Can I get health insurance for pre-existing mental health conditions in the UK?
You can apply, and the wording above shows what several insurers say about past conditions. What cannot be answered from a website is how an insurer would treat your own history, because that depends on the route, your dates and the insurer's judgement. The seven questions above are the place to start.
Does private medical insurance cover chronic conditions?
How a policy treats chronic conditions is a separate part of the wording from how it treats past ones. Chronic-condition clauses are quoted, with their sources, on the cheapest cover page. How an insurer applies that wording to ongoing mental health care depends on the policy, so ask which words in it mark the point where continuing care stops being paid; the broker can raise that with each insurer for you on a free call-back.
Can a past condition come into cover later?
Vitality's page 30 wording describes two unbroken years with no treatment, advice or medication once the plan has started, and also refers to conditions permanently excluded. Freedom's clause turns on whether Freedom agrees. Neither tells you how your own history would be treated.
Which insurer is best for pre-existing mental health?
No ranking holds, because the answer turns on how each insurer would treat your particular history, which only an application settles. The wording that can be compared is on the best options for a pre-existing condition page and the mental health comparison linked above.
Next step
Write down your dates, decide what mental health benefit you would want, and send in the form on this page. The broker who calls can then take those dates and the questions above to each insurer on the same terms.
