Navigating the world of private medical insurance (PMI) in the UK can feel complex, especially when you have existing health concerns. At WeCovr, an FCA-authorised broker that has helped arrange over 900,000 policies, we believe in clarity. This guide demystifies how insurers treat pre-existing conditions, helping you find the right cover.
One of the most common questions we hear is: "Will my private health insurance cover my pre-existing condition?"
The simple, direct answer is this: Standard UK private medical insurance is designed to cover new, acute medical conditions that arise after your policy begins. It does not typically cover pre-existing conditions or long-term, chronic illnesses that require ongoing management.
This might sound restrictive, but it’s the fundamental principle of how PMI works in the UK, complementing the brilliant care provided by our NHS. The NHS remains your primary provider for managing chronic conditions, handling emergencies, and treating any pre-existing issues. PMI is your key to accessing prompt private diagnosis and treatment for new eligible health problems.
In this guide, we'll break down everything you need to know, from how insurers define a pre-existing condition to the different ways they assess your health, so you can make an informed decision.
Understanding the difference between "acute" and "chronic" conditions is the first and most crucial step in grasping how private health insurance works. Insurers build their policies around this distinction.
Acute Conditions An acute condition is a disease, illness, or injury that is short-lived. It's likely to respond quickly to treatment, returning you to the state of health you were in before it started.
Private medical insurance is built to cover the diagnosis and treatment of acute conditions.
Chronic Conditions A chronic condition is a health problem that is long-lasting, has no known cure, and needs continuous management.
Private medical insurance does not cover the routine management of chronic conditions. Your GP and the NHS are your partners in managing these long-term illnesses. While some policies may offer limited cover for an acute flare-up of a chronic condition, the underlying condition itself remains excluded.
Insurers have a broad definition of a pre-existing condition. It isn't just about diagnosed illnesses. It generally includes any ailment or symptom for which you have:
This applies to a set period before your policy start date, which is typically the last five years.
Let's look at some examples:
| Scenario | Is it a Pre-Existing Condition? | Why? |
|---|---|---|
| You were diagnosed with asthma 10 years ago and use an inhaler daily. | Yes | You have a diagnosed chronic condition requiring ongoing treatment. |
| You had physiotherapy for a sore shoulder 3 years ago. | Yes | You sought advice and treatment for the condition. |
| You've had occasional knee pain for the last year but haven't seen a GP. | Yes | You have experienced symptoms, even without a formal diagnosis. |
| You were treated for a kidney infection 4 years ago and have been fine since. | Yes | You received treatment for the condition within the last 5 years. |
| You broke your arm 7 years ago, and it healed perfectly. | No | It happened more than 5 years ago and has not required further advice or treatment. |
The key takeaway is that insurers look at your recent medical history. Any health issue you've been aware of or had treated in the past few years will likely be considered pre-existing.
When you apply for private health cover, the insurer needs to understand your health status to determine what they can cover. This process is called "underwriting," and there are two main types in the UK: Moratorium Underwriting and Full Medical Underwriting (FMU).
This is the most common and straightforward way to get a policy started.
Real-Life Example: Sarah's Knee Pain Sarah took out a moratorium policy in January 2025. Two years prior, in 2023, she had seen her GP for knee pain. This knee pain is therefore a pre-existing condition and is automatically excluded from her cover.
This method involves a more detailed application process but provides complete certainty from day one.
Real-Life Example: David's Shoulder Injury David is applying for a policy with FMU. He declares that he dislocated his left shoulder five years ago and had a recurrence two years ago. The insurer reviews his application and offers him a policy with a specific exclusion: "Any treatment related to the left shoulder joint." David accepts this. Six months later, he develops a new problem with his right elbow. This is fully covered because it's an unrelated, new condition, and he knows his policy will pay for it. He has complete peace of mind.
| Feature | Moratorium Underwriting | Full Medical Underwriting (FMU) |
|---|---|---|
| Application Process | Quick and simple. No medical forms. | Longer. Requires a detailed health questionnaire. |
| Upfront Certainty | Low. You don't know what's covered until you claim. | High. Exclusions are clearly stated from the start. |
| Claim Process | Can be slower, as the insurer investigates your history at the point of claim. | Generally faster, as underwriting was done at the start. |
| Cover for Pre-Existing | Possible to gain cover after a 2-year trouble-free period. | Pre-existing conditions are usually excluded permanently. |
| Best For... | People with a clean bill of health or very minor past issues who want a quick start. | People who want absolute clarity on their cover, or have a complex history they wish to declare upfront. |
Working with an expert broker like WeCovr is invaluable here. We can explain the pros and cons of each option based on your personal health history and help you decide which path is right for you.
Even with the rules around pre-existing conditions, you can take steps to get the most suitable and comprehensive cover possible.
1. Be Completely Honest The golden rule is to be 100% truthful, whether you choose a moratorium or FMU policy. Failing to disclose a condition (non-disclosure) is a serious issue. If an insurer discovers you withheld information, they have the right to cancel your policy, refuse your claim, and you will have wasted your premiums.
2. Choose the Right Underwriting for You
3. Review Your Exclusions Periodically If you have an FMU policy with a specific exclusion, it doesn't always have to be for life. If you have been symptom-free for several years, you can ask the insurer to review the exclusion. They may agree to remove it, especially if your GP can provide a supporting letter.
4. Leverage Company Health Insurance If your employer offers a group private medical insurance scheme, the underwriting rules are often far more generous. Many company schemes cover pre-existing conditions, especially larger schemes with "Medical History Disregarded" (MHD) underwriting. If this is an option for you, it's often the best way to get cover for existing issues.
5. Talk to an Independent Broker This is perhaps the most important strategy. The private medical insurance UK market is vast, and every insurer has a slightly different appetite for risk and different underwriting philosophies. An independent, FCA-authorised broker like WeCovr works for you, not the insurer.
Here's a general guide to how insurers might approach some common conditions. This is for illustrative purposes only; the final decision always rests with the insurer's underwriting team.
| Condition | Typical Moratorium Approach | Typical Full Medical Underwriting (FMU) Approach |
|---|---|---|
| Mild, infrequent asthma | Excluded. Cover may be gained after 2 trouble-free years. | May be covered with a small premium loading, or may be excluded. |
| High Blood Pressure (Hypertension) | Excluded as a chronic condition. | Always excluded. Related conditions (heart, stroke) will also be excluded. |
| Anxiety or Depression (single past episode) | Excluded. Cover may be gained after 2 trouble-free years (no treatment/advice). | May be covered, but more likely to have a mental health exclusion applied. |
| Recurring Back Pain | Excluded. Gaining cover is difficult as even minor twinges can reset the 2-year clock. | A clear exclusion for the spine or a specific section of the spine will be applied. |
| Joint Pain (e.g., knee/hip) | Excluded if advice was sought in the last 5 years. | A specific exclusion for that joint will be applied. |
| Cancer (in remission for 5+ years) | May be covered under moratorium if no advice/treatment has occurred in the last 5 years. | Will be assessed on a case-by-case basis. An exclusion is likely but not guaranteed. |
While PMI focuses on treating new problems, the best strategy is always prevention. Leading a healthy lifestyle can reduce your risk of developing new conditions and can help you manage existing ones, potentially making you a more attractive applicant to insurers.
