Quick Answer: Can You Get Health Insurance with Pre-Existing Conditions?
Yes — you can almost always get UK private health insurance even with a pre-existing condition, but the condition itself usually won’t be covered, at least at first. Insurers typically exclude anything you’ve had symptoms, treatment, tests or medication for in the last 5 years. New, unrelated conditions that arise after your policy starts are still covered normally.
Under moratorium underwriting (the most common type), a pre-existing condition is excluded for the first 2 years — but can become covered if you go 2 continuous years symptom-free, treatment-free and advice-free. Under full medical underwriting, the insurer assesses your history upfront and tells you in writing what’s excluded — which can be better if your condition is fully resolved. Some insurers are noticeably more flexible than others, and chronic conditions needing ongoing management (like diabetes or asthma) are generally excluded by design. The key is choosing the right underwriting type and comparing insurers — this guide shows you how.
What this guide covers
If you have a health condition and want private cover, you’re not locked out — but you do need to understand how insurers handle medical history. This independent 2026 guide gives you the full picture. Going Private UK is editorially independent; we may earn commission when readers compare cover through our links, which funds our research but doesn’t affect our analysis.
Can You Get Health Insurance with a Pre-Existing Condition?
In almost all cases, yes — you can take out a policy. What changes is what’s covered. Most UK insurers will exclude conditions you already have, but you still get the core benefits of private cover for everything else:
- New, unrelated conditions that develop after the policy starts are covered normally
- Your existing condition may become covered later — after a symptom-free period under moratorium underwriting
- Fast diagnostic access for new symptoms — MRI, consultations, tests without long NHS waits
- Some conditions can be included from the start under full medical underwriting if they’re fully resolved
So even though your specific condition may be excluded, a policy still protects you against the next health issue — which is the main reason cover is still worth having. For the bigger picture on buying cover, see our guides to how to get private medical insurance and comprehensive vs basic cover.
What Counts as a Pre-Existing Condition?
This is where many people get caught out. UK insurers generally apply a 5-year “look-back” rule: a condition is treated as pre-existing if, in the last 5 years, you’ve had any of:
- Symptoms — even if you never got a diagnosis
- Treatment — including surgery, physiotherapy or procedures
- Medication — including repeat prescriptions
- Tests or investigations — scans, blood tests, referrals
- Medical advice — even a GP conversation about it
Crucially, it doesn’t need to be formally diagnosed to count. If you saw a GP about knee pain three years ago, that knee may be treated as pre-existing even without a diagnosis. Common examples include diabetes, asthma, high blood pressure, heart conditions, past or current cancer, joint problems, back pain, and mental health conditions such as anxiety or depression.
Moratorium vs Full Medical Underwriting
How your medical history is handled depends entirely on the underwriting type you choose. This is the single most important decision when you have a pre-existing condition.
| Underwriting type | How it works | Best for |
|---|---|---|
| Moratorium | No medical questions at sign-up. Conditions from the last 5 years are automatically excluded — but each can become covered after 2 continuous years symptom-free, treatment-free and advice-free. | Fast sign-up; conditions that may improve or resolve |
| Full Medical Underwriting (FMU) | You complete a detailed health questionnaire upfront. The insurer tells you in writing exactly what’s excluded — sometimes permanently, sometimes temporarily. | Resolved conditions; certainty about what’s covered |
💡 The key insight most people miss
If your condition is fully resolved, full medical underwriting (FMU) may actually cover it from day one — whereas moratorium would exclude it for at least 2 years. But if your condition is ongoing or recent, moratorium is faster and avoids upfront scrutiny. Choosing the right one for your situation can be the difference between cover and exclusion. Our full guide to moratorium vs full medical underwriting walks through which to pick.

Which UK Insurers Are Most Flexible on Pre-Existing Conditions?
Insurers vary in how they treat medical history — both in underwriting approach and in how they handle specific conditions. Here’s an honest 2026 overview.
| Insurer | Approach to pre-existing conditions |
|---|---|
| Bupa | Offers both moratorium and FMU. Strong structured pathways for cancer and ongoing monitoring; conditions may be covered after the standard symptom-free period. |
| AXA Health | Both underwriting types. Mental health history is often handled cautiously; many physical conditions reviewed under the 2-year moratorium rule. |
| Vitality | Can be more flexible for lifestyle-related conditions, assessed case-by-case; rewards programme can support better management. |
| WPA | Known for transparency — clear written exclusions and timelines, which many find reassuring with a complex history. |
| Freedom Health Insurance | Often considered flexible for niche or complex cases; modular structure. |
| The Exeter | Offers medical history disregarded options in some circumstances — potentially valuable if existing conditions complicate other applications. |
There’s no universal “most flexible” insurer — it depends on your specific condition. This is exactly where comparing several insurers (or using a broker) pays off. See our best UK health insurance reviews and guide to health insurance brokers.
How Specific Conditions Are Usually Treated
- Diabetes (Type 1 & 2): the diabetes itself is a chronic condition and usually excluded, but cover for unrelated new issues continues normally
- Asthma: typically excluded as ongoing management, though may be covered after a symptom-free period if mild and historic
- High blood pressure: if well-controlled, often has limited impact on unrelated cover
- Heart conditions: usually excluded for related treatment; new unrelated conditions still covered
- Cancer: recent cancer (within 5 years) is generally excluded; after longer remission some insurers reconsider — see our guide on health insurance after a cancer diagnosis and cancer cover
- Mental health (anxiety, depression): history is often excluded or limited; see our mental health cover guide
- Back & joint pain: commonly excluded if recent; the most frequently caught-out “minor” pre-existing issue
For conditions excluded by underwriting, remember the trade-off: the policy still gives you fast access for everything else, which is where most of the value sits.
How Much Does Health Insurance Cost with a Pre-Existing Condition?
A common myth is that a pre-existing condition automatically makes your premium expensive. In reality, because the condition is usually excluded rather than priced in, your premium is often similar to a standard policy — you’re simply covered for less. Typical 2026 ballpark figures:
| Age | Typical monthly cost | Notes |
|---|---|---|
| 30–40 | £35–£65 | Mild/controlled conditions often have little price impact |
| 40–50 | £50–£90 | Joint or mental-health history may add exclusions rather than cost |
| 50–60 | £90–£150 | Premiums rise with age and medical inflation |
| 60+ | £130–£250+ | Age is the bigger driver than the condition itself |
Prices vary by postcode, excess, hospital list and cover level. To manage cost, see our guides to choosing your excess and why premiums rise each year.
Switching Insurer with a Pre-Existing Condition (CPME)
If you already have cover and want to switch, this is critical: switching the wrong way can restart your waiting periods and re-exclude conditions you’d already cleared.
- Continued Personal Medical Exclusions (CPME) — the right way to switch. Your existing exclusions transfer to the new insurer rather than being re-underwritten, so you don’t lose progress. See our CPME guide
- Don’t switch to fresh underwriting without advice — you could lose a condition you’d already brought back into cover under moratorium
- Always ask specifically whether a new insurer will honour your existing terms before moving
For a full walkthrough see our guide on how to switch health insurance without losing cover.
How to Improve Your Chances of Cover
- Choose the right underwriting — moratorium for speed, FMU if your condition is resolved and you want it included
- Be completely honest — non-disclosure is the main reason claims get rejected; full honesty protects your future claims
- Consider employer or group cover — corporate schemes often use medical history disregarded underwriting that ignores conditions entirely. See corporate cover
- Use a broker — they know which insurers are kindest to your specific condition
- Wait out the moratorium — staying symptom-free can bring a condition back into cover after 2 years
What Usually Isn’t Covered
- Chronic conditions needing ongoing management — diabetes, asthma, ongoing heart conditions (PMI covers acute, curable issues, not long-term management)
- Lifelong/repeat prescriptions for an existing condition
- Cancer diagnosed within the last 5 years (varies by insurer and remission length)
- Currently ongoing pregnancy-related issues
- Recent symptoms or treatment within the look-back window, until cleared
Understanding these limits upfront prevents the single biggest source of disappointment — see what’s worth paying for.
Is Health Insurance Still Worth It If My Condition Won’t Be Covered?
✓ Why it’s often still worth it
- Protects against new conditions — your next health issue is covered
- Fast diagnostics for new symptoms — no long NHS waits
- The condition may become covered after the moratorium period
- Choice of consultant and hospital for everything unrelated
- Premium often similar to a standard policy (condition excluded, not priced in)
✗ When it may not be
- If your only concern is the existing condition — that’s exactly what’s excluded
- Chronic management needs — better served by the NHS
- Very recent serious diagnosis — broad exclusions may limit value initially
- Tight budget — a cash plan or basic policy may suit better

The honest verdict
Having a pre-existing condition doesn’t lock you out of private health insurance — but it does change what you’re buying. In almost all cases you can get a policy; the condition itself is usually excluded, while everything else (new conditions, fast diagnostics, choice of hospital) is covered normally.
The two decisions that matter most are which underwriting type you choose (moratorium for speed, full medical underwriting if your condition is resolved) and which insurer you go with, since flexibility varies significantly. If you already have cover, switch only via CPME so you don’t lose ground.
For most people with a manageable or historic condition, cover is still genuinely worth it — it protects against the next health problem and gives fast access for everything unrelated. Compare quotes to see how each insurer would treat your specific history.
Frequently Asked Questions
Can you get health insurance with pre-existing conditions in the UK?
Yes — in almost all cases you can take out a policy. The pre-existing condition itself is usually excluded (permanently, or until you’ve been symptom-free for 2 years under moratorium underwriting), but new unrelated conditions are covered normally. You still get fast diagnostics and treatment for everything other than the excluded condition.
What counts as a pre-existing condition for health insurance?
UK insurers generally use a 5-year look-back: any condition you’ve had symptoms, treatment, medication, tests or medical advice for in the last 5 years is treated as pre-existing. It doesn’t need to be formally diagnosed — even a GP conversation about a symptom can count.
Will a pre-existing condition be covered after 2 years?
Under moratorium underwriting, yes — potentially. If you go 2 continuous years after the policy starts without symptoms, treatment, medication or advice for that condition, it can become covered. If symptoms recur during that period, the clock typically resets. Full medical underwriting works differently — exclusions are set in writing upfront.
Does a pre-existing condition make health insurance more expensive?
Often not as much as people expect. Because the condition is usually excluded rather than priced into the premium, your monthly cost is frequently similar to a standard policy — you’re simply covered for less. Age, postcode, excess and cover level usually affect price more than the condition itself.
Which UK insurer is best for pre-existing conditions?
There’s no single best — it depends on your specific condition. WPA is known for transparency, The Exeter offers medical-history-disregarded options in some cases, and Bupa has structured pathways for conditions like cancer. Because flexibility varies by condition, comparing several insurers or using a broker is the best approach.
Can I get health insurance if I have diabetes?
Yes, you can take out a policy, but the diabetes itself (as a chronic condition needing ongoing management) is generally excluded. Cover for new, unrelated conditions continues normally. Some insurers handle well-managed diabetes more favourably than others, so comparing is worthwhile.
Can I get cover after a cancer diagnosis?
Cancer diagnosed within the last 5 years is generally excluded. After longer periods of remission, some insurers will reconsider related cover. You can still get a policy that covers unrelated new conditions in the meantime. See our guide on health insurance after a cancer diagnosis for detail.
What is the difference between moratorium and full medical underwriting?
Moratorium means no medical questions at sign-up, but conditions from the last 5 years are excluded (and may be covered after 2 symptom-free years). Full medical underwriting means you disclose your history upfront and the insurer confirms in writing exactly what’s excluded — which can cover a resolved condition from day one. Moratorium is faster; FMU gives certainty.
Can I switch health insurance if I have a pre-existing condition?
Yes, but switch carefully. Use Continued Personal Medical Exclusions (CPME) so your existing exclusions transfer rather than being re-underwritten — otherwise you could restart waiting periods and re-exclude conditions you’d already brought back into cover. Always confirm the new insurer will honour your existing terms before moving.
Is health insurance worth it if my condition won’t be covered?
For most people, yes. Even with the condition excluded, the policy protects you against new, unrelated illnesses, gives fast diagnostic access for new symptoms, and offers choice of consultant and hospital. It’s less worthwhile if your only concern is the existing condition itself, which is exactly what’s excluded.
Does employer health insurance cover pre-existing conditions?
Often yes — many corporate and group schemes use “medical history disregarded” (MHD) underwriting, which ignores medical history entirely and covers pre-existing conditions. This is one of the biggest advantages of cover through an employer versus an individual policy.
