Health Insurance Exclusions UK: What Every Policy Won’t Cover
Most disappointing claims come down to one of two lists, and most buyers never read either. There are general exclusions that apply to everyone, such as chronic conditions, A&E and pregnancy, and personal exclusions that apply to you, mainly pre-existing conditions. This guide sets out the full UK list using insurers’ own published wording, the chronic-condition rule that confuses almost everyone, the two-year moratorium rule, what makes an exclusion permanent, and how to end up with the fewest.
Quick Answer
UK health insurance has two kinds of exclusion. General exclusions are the same for every customer and barely differ between the big insurers. Bupa’s published list is a representative example: chronic conditions, pre-existing conditions, emergency care, pregnancy and childbirth, fertility treatment, cosmetic treatment (unless there’s a medical reason), allergies, dialysis, eye correction, gender dysphoria, learning difficulties, overseas treatment and varicose veins. Many policies also limit treatment linked to drug or alcohol misuse, self-inflicted injury and some hazardous sports. Personal exclusions depend on your medical history and on your underwriting choice. Under moratorium, recent conditions are excluded until you’ve gone two continuous years without symptoms, treatment or advice. Under full medical underwriting, specific exclusions are named in your policy from day one and can be permanent.
The honest takeaways. No personal policy is exclusion-free. The chronic-condition exclusion usually still covers diagnosis and acute flare-ups, just not long-term management. Several gaps, such as dental, optical and extra mental-health cover, can be closed with add-ons. And personal exclusions pile up as your medical history grows, which is the strongest case for buying while you’re healthy. Pre-existing conditions get their own full guide: health insurance with pre-existing conditions.

General vs Personal Exclusions
Every claim that gets declined for a coverage reason fails one of two tests, and they work differently:
- General exclusions are written into the policy for everyone. They reflect what private medical insurance is designed to do: cover the diagnosis and treatment of acute conditions that start after you join. They are why insurance won’t pay for your A&E visit, your pregnancy or the long-term management of your diabetes. They barely vary between the major insurers, so switching brands rarely helps with them.
- Personal exclusions apply only to you, because of your medical history. They arrive through underwriting, either automatically (moratorium) or by name (full medical underwriting). These are what separate one customer’s cover from another’s, and the underwriting route you choose shapes them far more than the brand you buy.
One useful habit before buying anything: read the policy’s key facts document. It is short, standardised, and lists the general exclusions in plain English. Ten minutes with it prevents most of the surprises this page describes.
The General Exclusions List
This uses the categories insurers publish, with Bupa’s list as a representative example. Wording and detail vary by insurer and product, so treat this as a map and the key facts document as the final word:
| Commonly excluded | What it means in practice | The route instead |
|---|---|---|
| Chronic conditions | Ongoing management of long-term illness | NHS for management; diagnosis and flare-ups often covered (see below) |
| Pre-existing conditions | Conditions before the policy started | Depends on underwriting; see pre-existing guide |
| Emergency care | A&E and emergency admissions | NHS A&E; see private emergency care explained |
| Pregnancy & childbirth | Routine maternity care and delivery | NHS or self-pay; some maternity add-ons exist |
| Fertility treatment | IVF and fertility investigations | Self-pay or NHS criteria |
| Cosmetic treatment | Treatment for appearance only | Reconstructive surgery with a medical reason may be covered |
| Dental & optical | Routine dental and eye care | Add-on modules; see dental cover explained |
| Allergies, dialysis, eye correction, varicose veins | Specific named categories | NHS or self-pay |
| Drug/alcohol misuse, self-inflicted injury | Treatment linked to these causes | NHS services; wording varies by insurer |
| Some hazardous sports | Injuries from named dangerous pursuits | Check wording; see sports injury cover |
| Overseas treatment | Treatment abroad | Travel insurance or international policies |
Emergency care deserves a line of its own because it’s a safety issue, not just a coverage one. Private health insurance is not for emergencies. Chest pain, stroke symptoms and serious injuries go to 999 and NHS A&E, whatever policy you hold.
The Chronic-Condition Rule
This is the exclusion that causes more confused calls to insurers than any other, and it is not as blunt as it sounds. Bupa defines chronic conditions as ones needing “ongoing or long-term control or relief for symptoms”, or “likely to last for the rest of your life or a very long time”, often with no known cure. Diabetes, asthma, arthritis, high blood pressure and multiple sclerosis all fit.
What the rule usually means in practice:
- Diagnosis is often covered. If you develop new symptoms after joining, insurers commonly pay to investigate them, including consultations and scans, even when the answer turns out to be a chronic condition.
- Acute flare-ups are often covered. Treating a sudden worsening, where the aim is to get you back to how you were, typically counts as acute treatment.
- Long-term management is not. Once a condition is stable and needs ongoing monitoring, check-ups and repeat prescriptions, that care goes back to the NHS.
The key exception is cancer. It’s often long-running, but insurers commonly treat it as core cover. Cancer benefits and limits are one of the biggest differences between policies, which is a good reason to compare cover rather than just price. Exactly where a policy draws the line between diagnosis, flare-up and management is in its wording, so check it before relying on it.
Personal Exclusions: Moratorium, Full Underwriting & Permanent Exclusions
Your personal exclusions depend on how the policy is underwritten. The UK has three main routes:
- Moratorium. You don’t declare your history up front. Instead, conditions you’ve had symptoms, treatment, medication or advice for in roughly the last five years are automatically excluded. The two-year rule gives the way out: once you’ve been on cover for two continuous years without any of those for a condition, it can become eligible. You don’t find out what’s excluded until you claim.
- Full medical underwriting. You declare your history and the insurer names specific exclusions in your policy. You know exactly where you stand from day one, but named exclusions can be permanent for the life of the policy unless the insurer agrees to review them.
- Continued personal medical exclusions (CPME). Used when switching insurers. The new insurer takes on your existing exclusions and underwriting position rather than starting fresh. This protects a moratorium clock you’ve already built up, but it also carries your existing exclusions with you. The mechanics are in our switching guide.
Which route suits you depends on how much medical history you have and how much certainty you want. Our moratorium vs full medical underwriting guide covers it properly. One rule applies to all three: answer every health question honestly. Non-disclosure is the most common reason for claims being declined or policies being cancelled.
Mental Health: Covered, Limited or Excluded?
Mental health is where general exclusions and optional cover overlap most. Many core policies include some inpatient psychiatric cover but cap or leave out outpatient therapy unless you add a mental-health option. Limits vary widely: a number of sessions, a yearly amount, or full cover. Some insurers include digital or direct-access therapy routes as standard. Our mental health cover guide compares the approaches, with detail by insurer for Bupa and AXA. The usual underwriting rules also apply: a history of anxiety or depression is typically a pre-existing condition. (Searching for mental-health exclusions on life insurance instead? That’s a different product with different rules, covered in life insurance and mental health.)
How to End Up With the Fewest Exclusions
- Buy while you’re healthy. Personal exclusions build up as your medical history does, so every year you wait can add to the list you’d start with.
- Choose your underwriting deliberately. Moratorium versus full medical underwriting is a real decision, not a form default.
- Close the gaps that matter to you. Outpatient limits, mental-health options and dental or optical modules decide more of your real-world cover than the brand does. See our outpatient limits guide.
- Switch with CPME, never cancel first. Get the new insurer’s terms in writing before you end an old policy.
- Through work? Medical history disregarded (MHD) underwriting ignores pre-existing conditions entirely, but it’s generally only available on company schemes. The general exclusions still apply even then.

FAQs: Health Insurance Exclusions (2026)
What are exclusions in health insurance?
An exclusion is something a policy will not pay for, written into the policy wording. UK health insurance has two kinds, and confusing them causes most claim disappointments. General exclusions apply to everyone on the policy — the same list for every customer: chronic conditions, emergency care, normal pregnancy and childbirth, cosmetic treatment, and so on. Personal exclusions apply to you specifically, because of your medical history — usually pre-existing conditions, handled either by moratorium underwriting (conditions from roughly the last five years excluded until you have gone two continuous years on cover without symptoms, treatment or advice) or by full medical underwriting (named exclusions written into your policy from day one). The practical point: general exclusions barely differ between the major insurers, while personal exclusions depend heavily on the underwriting route you choose — so that choice matters more than most buyers realise.
What does private health insurance not cover in the UK?
The common general exclusions, taking Bupa’s published list as a representative example: chronic conditions (ongoing management of long-term illnesses like diabetes or asthma), pre-existing conditions, emergency care (A&E stays with the NHS), pregnancy and childbirth, fertility treatment, cosmetic treatment (unless there is a medical reason, such as reconstruction), allergies and food intolerances, dialysis, eye-correction treatment, gender dysphoria, learning difficulties, overseas treatment and varicose veins — with many policies also excluding or limiting treatment linked to drug or alcohol misuse, self-inflicted injury, and some hazardous sports. Two things soften that list more than people expect. First, several items are available as add-ons: dental and optical cover, extended mental health cover and, at some insurers, maternity-related benefits. Second, the chronic-condition exclusion usually still pays for diagnosis and for treating an acute flare-up — it is the long-term management that returns to the NHS. Every insurer’s wording differs in the detail, so the policy’s key facts document is the final word.
What is a permanent exclusion in health insurance?
A permanent exclusion is a condition your policy will never cover, however long you hold it. In the UK they mostly arise under full medical underwriting: you declare your history, and the insurer writes named exclusions into your policy — a previous back problem, say — which typically stay for the life of the policy unless the insurer agrees to review them. Moratorium underwriting works differently: pre-existing conditions are excluded at first, but not permanently — a condition can become eligible once you have been on cover for two continuous years without symptoms, treatment, medication or advice for it. That difference is the heart of the underwriting choice: full medical underwriting gives certainty up front, possibly including permanent exclusions, while moratorium gives a route to eventual cover but leaves you unsure what is covered until you claim. When switching insurers, existing exclusions can carry across under continued personal medical exclusions (CPME) terms — which protects moratorium clocks already running, but also carries any existing exclusions over. Never cancel a policy before the replacement’s terms are confirmed in writing.
Is there health insurance with no exclusions?
Not for an individual buying their own policy — every UK personal policy has general exclusions, and any claim otherwise deserves suspicion. The nearest thing is medical history disregarded (MHD) underwriting, which ignores pre-existing conditions entirely: it is offered on company schemes, usually requiring a minimum group size that varies by insurer, and even MHD policies keep the general exclusions (chronic management, emergencies, cosmetic and so on). For individuals, the honest ways to end up with the fewest exclusions are: buy while you are healthy, since exclusions accumulate as your medical history does; choose your underwriting route deliberately rather than taking the default; add the modules that close the gaps that matter to you (outpatient limits, mental health, dental and optical); and when switching, use CPME terms so you do not restart moratorium clocks. Comparing policies on exclusions and limits, not just price, is where insurers actually differ.
Important Information
This 2026 guide is independent general information, not financial or medical advice. Exclusions, definitions, limits and underwriting terms vary by insurer and product and change over time. The lists above reflect insurers’ published information at the time of writing and are representative, not a guarantee of any particular policy’s terms. Always read the key facts document and full policy wording, and confirm cover with the insurer in writing before relying on it. Answer all application questions accurately, because non-disclosure can affect claims. For medical emergencies, call 999 or go to NHS A&E. Going Private UK is not affiliated with any insurer named.
