As an FCA-authorised broker that has helped arrange over 800,000 policies, WeCovr understands that navigating the UK private medical insurance market can feel complex. This expert guide clarifies how pre-existing conditions affect your eligibility for private health cover, empowering you to make an informed decision.
Understanding private medical insurance (PMI) starts with one core principle: it's designed to cover new, unexpected health problems that arise after your policy begins. This means that any health issue you had before taking out cover, known as a "pre-existing condition," is typically excluded.
This guide will walk you through:
The great news is that having a pre-existing condition doesn't usually stop you from getting private health insurance; it simply means that specific condition won't be covered. You can still benefit from fast access to private treatment for a wide range of new, eligible health issues.
In the world of UK health insurance, a "pre-existing condition" is any disease, illness, or injury for which you have experienced symptoms, received medication, sought advice, or had treatment before your policy's start date.
This definition is broad. It includes not just diagnosed illnesses but also symptoms you may have had that were not yet formally diagnosed.
Common examples include:
UK private medical insurance is built to cover acute conditions. This is the single most important concept to grasp.
Standard PMI policies will not cover the ongoing management of chronic conditions. This is because insurance works by covering unforeseen events, whereas the costs associated with a chronic condition are predictable and long-term. Covering them would make premiums unaffordable for everyone.
| Feature | Acute Condition | Chronic Condition |
|---|---|---|
| Onset | Usually sudden | Often gradual |
| Duration | Short-term | Long-term or lifelong |
| Treatment Goal | To cure or fully resolve the issue | To manage symptoms and slow progression |
| PMI Coverage | Generally Covered (if it's a new condition) | Generally Excluded |
| Examples | Broken arm, appendicitis, hernia | Diabetes, arthritis, hypertension, asthma |
When you apply for a policy, the insurer needs to understand your medical history to determine which conditions, if any, will be excluded. They do this using one of two methods of "underwriting."
Moratorium is the most common type of underwriting for individual PMI policies. It's often quicker because you don't need to fill out a detailed medical questionnaire upfront.
How it works:
Example: David had physiotherapy for a shoulder injury 3 years before buying a policy with moratorium underwriting.
| Pros of Moratorium | Cons of Moratorium |
|---|---|
| ✅ Quicker and simpler application | ❌ Lack of certainty at the start |
| ✅ No lengthy medical forms | ❌ Claims process can be slower as checks are done then |
| ✅ Conditions can become eligible for cover over time | ❌ The "2-year clock" can reset, causing confusion |
With Full Medical Underwriting, you provide your complete medical history to the insurer at the start by filling out a detailed questionnaire.
How it works:
Example: Priya has a history of migraines, which she declares on her application. The insurer reviews her history and decides to place a permanent exclusion on migraines and related neurological investigations. Priya knows from day one that her PMI will not cover her migraines, but it will cover a new, unrelated issue like a knee ligament tear.
| Pros of Full Medical Underwriting | Cons of Full Medical Underwriting |
|---|---|
| ✅ Complete clarity from day one | ❌ Application process is longer and more intrusive |
| ✅ You know exactly what is and isn't covered | ❌ Exclusions are usually permanent |
| ✅ Claims are often faster as history is already known | ❌ Requires gathering detailed medical information |
An expert broker, like WeCovr, can explain these options in detail and help you decide which underwriting method is best suited to your personal circumstances.
Yes, absolutely. Having a pre-existing condition rarely prevents you from getting a private health insurance policy in the UK.
The key takeaway is that while you can get a policy, the pre-existing condition itself (and any closely related conditions) will be excluded from cover. The real value of the policy is that it protects you against the cost of treatment for new and unrelated acute conditions that you might develop in the future.
Real-Life Scenario:
As we've established, PMI is for acute conditions. Chronic conditions are almost always excluded from cover. According to the Office for National Statistics (ONS), in 2022 an estimated 46.3% of adults in England reported having at least one long-term health condition. This highlights why insurers have to be clear about this distinction to keep policies viable.
Common Chronic Conditions Excluded from PMI:
| Condition | Why It's Excluded | What This Means for You |
|---|---|---|
| Diabetes (Type 1 & 2) | Requires lifelong monitoring and management. | Your PMI will not cover insulin, check-ups, or diabetes-related complications. |
| Hypertension (High Blood Pressure) | A long-term condition needing regular medication and monitoring. | Your policy won't pay for GP visits or medication for blood pressure. Related issues like heart disease may also be excluded. |
| Arthritis (Osteo or Rheumatoid) | A progressive, long-term condition with no known cure. | Joint replacements may be covered if the condition arises after the policy starts, but ongoing management is not. |
| Asthma | Requires long-term use of inhalers and management. | Your policy will not cover the cost of inhalers, respiratory reviews, or emergency treatment for an asthma attack. |
| Crohn's Disease / Ulcerative Colitis | Long-term inflammatory bowel diseases requiring ongoing specialist care. | Consultations, medication, and surgeries related to the condition will be excluded. |
Some high-end policies may offer limited benefits for monitoring chronic conditions, but this is not standard. Always read your policy documents carefully.
Be 100% Honest: When applying, especially with Full Medical Underwriting, disclose everything. Failing to declare a condition, even if you think it's minor, is called "non-disclosure." If discovered later, it can lead to a claim being rejected or your entire policy being cancelled.
Choose Your Underwriting Wisely:
Work with an Expert Broker: This is the single most effective step you can take. A specialist broker like WeCovr works for you, not the insurer. We can:
Review Your Policy Documents: Once you receive your policy certificate, read the exclusions section carefully. This is your contract with the insurer. If something doesn't look right, query it immediately.
Consider Company Schemes: If your employer offers a group health insurance scheme, it may have "Medical History Disregarded" (MHD) underwriting. This is the most generous type, often covering pre-existing conditions. If available, it's usually an excellent option.
While insurance covers you when things go wrong, taking control of your health can reduce the risk of needing to claim and improve your overall quality of life. Managing a condition well may also help you meet the criteria for moratorium underwriting in the future.
