Navigating the world of private medical insurance (PMI) in the UK can feel daunting, especially if you have a pre-existing health condition. At WeCovr, an FCA-authorised broker that has helped arrange over 800,000 policies, we believe everyone deserves clarity. This guide demystifies how PMI works with existing health issues.
How to secure cover if you have existing health issues, and which providers are most inclusive
Finding private health cover when you have a medical history is one of the most common challenges faced by UK consumers. The fundamental principle of private medical insurance is to cover unexpected, acute conditions that arise after your policy begins. It is not designed to cover the ongoing management of long-term (chronic) illnesses or treatment for health issues you already have.
However, this doesn't mean you can't get a valuable policy. The key lies in understanding how insurers assess your health history—a process known as underwriting. By choosing the right underwriting method and the right provider, you can secure a policy that gives you peace of mind for new, eligible conditions, even if certain past issues are excluded.
This guide will walk you through:
- The crucial difference between moratorium and full medical underwriting.
- How insurers define "pre-existing" and "chronic" conditions.
- Which leading UK providers offer the most flexible approaches.
- How an expert broker can help you find the best possible terms.
Understanding "Pre-Existing" and "Chronic" in the Eyes of an Insurer
Before diving into how to get cover, it's vital to speak the same language as the insurers. These two terms are the bedrock of any PMI policy decision.
What is a Pre-Existing Condition?
From an insurer's perspective, a pre-existing condition isn't just a formal diagnosis. It is any disease, illness, or injury for which you have experienced symptoms, received medication, advice, or treatment before the start of your policy.
This is a broad definition. It could include:
- A diagnosed condition like asthma or eczema.
- A joint injury from playing sports five years ago.
- Symptoms like recurring headaches or back pain, even if you never received a formal diagnosis.
- Mental health conditions for which you've sought therapy or medication.
Insurers exclude these conditions to manage risk. A core principle of insurance is to protect against the unknown. Covering conditions that are already known, and likely to require treatment, would make premiums prohibitively expensive for everyone. Think of it like trying to buy car insurance after you've had an accident—the policy is designed to cover future events, not past ones.
What is a Chronic Condition?
A chronic condition is a long-term health issue that is likely to continue indefinitely. These conditions cannot be cured but can be managed through monitoring, check-ups, and medication.
Examples of common chronic conditions include:
- Diabetes
- Arthritis
- Hypertension (high blood pressure)
- Crohn's disease
- Asthma
- Most types of heart disease
Standard UK private medical insurance does not cover the routine management of chronic conditions. This is because their treatment is ongoing and predictable, falling outside the scope of insurance for acute, short-term illnesses. While your PMI policy won't cover your regular diabetes check-ups or asthma inhalers, it would cover an eligible acute condition that arises separately from your chronic illness.
The Two Gates to Cover: Moratorium vs. Full Medical Underwriting
When you apply for PMI, the insurer needs to understand your medical history to decide what they will and won't cover. They do this using one of two methods: Moratorium or Full Medical Underwriting (FMU). Choosing the right one for your circumstances is the single most important decision you'll make.
1. Moratorium (MORI) Underwriting
This is the most common and quickest way to get a policy.
- How it works: You do not complete a detailed medical questionnaire. Instead, the policy automatically excludes any pre-existing conditions you've had in the five years leading up to your policy start date.
- The "Two-Year Rule": The magic of a moratorium policy is that these exclusions can be lifted. If you go for a continuous two-year period after your policy starts without having any symptoms, treatment, medication, or advice for that specific condition, it may become eligible for cover in the future.
- Pros:
- Fast and Simple: No lengthy forms to fill out.
- Less Intrusive: You don't have to disclose your entire medical history upfront.
- Potential for Future Cover: Conditions can become eligible for cover over time.
- Cons:
- Lack of Certainty: You won't know for sure if a condition is covered until you make a claim. The insurer will investigate your medical history at that point.
- The "Clock" Can Reset: If you have a flare-up or even a GP check-up for an old condition during the two-year waiting period, the clock resets, and you must start another two-year symptom-free period.
Example:
Jane had physiotherapy for knee pain three years before buying a moratorium policy. For the first two years of her policy, any treatment related to her knee is automatically excluded. If she remains completely symptom-free and needs no advice or treatment for her knee during those two years, a new knee problem in her third year could be covered.
2. Full Medical Underwriting (FMU)
This method involves a more detailed, upfront assessment of your health.
- How it works: You complete a comprehensive health questionnaire, declaring your medical history. The insurer's underwriting team reviews this information and may ask for more details or access to your medical records (with your consent).
- The Outcome: The insurer provides you with a policy document that explicitly lists any specific exclusions. These exclusions are usually permanent.
- Pros:
- Complete Certainty: You know exactly what is and isn't covered from day one. There are no surprises at the point of a claim.
- Potentially Fewer Exclusions: Sometimes, if a condition was very minor or a long time ago, an underwriter might choose not to apply an exclusion, which wouldn't be possible with a moratorium's blanket approach.
- Cons:
- Slower Process: The application can take several weeks.
- More Intrusive: You have to provide detailed personal health information.
- Exclusions are Often Permanent: Once an exclusion is on your policy, it's very unlikely to be removed.
Example:
David has a history of mild IBS. He declares this on his FMU application. The insurer reviews his case and applies a permanent exclusion for any investigations or treatment related to irritable bowel syndrome. David is disappointed but is glad to know exactly where he stands. All other new, acute conditions are covered as normal.
Which Underwriting Option is Right for You? A Comparison
| Feature | Moratorium Underwriting | Full Medical Underwriting (FMU) |
|---|
| Application Process | Quick and simple, no health forms. | Slower, requires a detailed health questionnaire. |
| Initial Exclusions | Automatically excludes conditions from the last 5 years. | Exclusions are based on your specific medical history. |
| Clarity of Cover | Can be uncertain until a claim is made. | Crystal clear from the start. |
| Future Cover | Pre-existing conditions may become eligible after a 2-year clear period. | Exclusions are typically permanent. |
| Best For... | People with minor or no recent health issues who want a quick start. | People with a complex medical history who want certainty above all else. |

Beyond Insurance: A Proactive Approach to Your Wellbeing
While PMI focuses on treating new conditions, taking control of your overall health is the best investment you can ever make. Many insurers now actively support this, but the power lies in your daily habits.
- Nutrition: A balanced diet is fundamental to managing many conditions. The NHS Eatwell Guide is an excellent resource for building healthy meals. As a WeCovr client, you also get complimentary access to CalorieHero, our AI-powered calorie and nutrition tracking app, to help you stay on track.
- Physical Activity: The NHS recommends at least 150 minutes of moderate-intensity activity a week. This could be brisk walking, cycling, or swimming. Regular exercise helps manage weight, blood pressure, and blood sugar levels, and is a powerful mood booster.
- Quality Sleep: Aim for 7-9 hours of quality sleep per night. Poor sleep can worsen inflammation and impact your immune system. Creating a relaxing bedtime routine and a dark, quiet environment is key.
- Mental Resilience: Stress can trigger or worsen many physical health conditions. Practices like mindfulness, meditation, or simply spending time in nature can have a profound impact. Most PMI providers now offer access to mental health support lines or apps as part of their standard package.
Purchasing a PMI or Life Insurance policy through WeCovr can also unlock discounts on other types of cover, helping you protect your family's broader financial wellbeing.
Real-Life Scenarios: How Underwriting Plays Out
Let's look at how these rules apply in practice.
Scenario 1: Sarah and her Sore Shoulder (Moratorium)
Sarah had physiotherapy for shoulder pain caused by a gym injury in 2022. In 2025, she takes out a PMI policy with moratorium underwriting.
- The Situation: For the first two years of her policy (until 2027), any medical care related to her shoulder will be excluded because it was a pre-existing condition within the last 5 years.
- The Outcome: Sarah is careful and has no further shoulder trouble. In 2028, she develops a completely new pain in the same shoulder. Because she has completed the two-year symptom-free period, her insurer agrees to cover the investigations and potential treatment.
Scenario 2: Mark and his Medical History (Full Medical Underwriting)
Mark has a history of gout and high cholesterol, both managed by medication. He wants absolute clarity on what will be covered.
- The Situation: He opts for an FMU policy and declares both conditions on his application form.
- The Outcome: The insurer issues his policy with two specific, permanent exclusions: one for "gout and related conditions" and another for "management of high cholesterol." Mark is fully covered for any other new, acute condition, from a hernia repair to cancer treatment, and is happy knowing there will be no grey areas if he needs to claim.
Scenario 3: Fatima and Switching Insurers (Continued Medical Exclusions)
Fatima has been insured with Provider A for six years. During that time, she developed asthma, which Provider A has covered. She finds a cheaper policy with Provider B.
- The Situation: If she simply cancels and takes out a new policy, her asthma will now be a pre-existing condition and will be excluded by Provider B.
- The Solution: She speaks to a broker at WeCovr, who finds an insurer that offers "Continued Medical Exclusions" (CME) or "Switch" terms. Provider B agrees to take on Fatima's underwriting from Provider A, meaning they will continue to offer cover for her asthma on the same terms. She successfully switches providers without losing her valuable cover.
Do I need to declare every single cold or minor GP visit on a PMI application?
Generally, no. For a Full Medical Underwriting application, insurers are interested in significant illnesses, injuries, symptoms, and diagnosed conditions, particularly from the last five years. You don't need to list every common cold. However, if you have recurring symptoms, such as persistent headaches or digestive issues that you've seen a doctor about, you must declare them. If in doubt, it is always best to declare it. With moratorium underwriting, you don't declare anything upfront.
What happens if I don't declare a pre-existing condition?
This is known as non-disclosure and is a serious issue. If you make a claim and the insurer discovers you failed to declare a relevant condition on an FMU application, they have the right to refuse the claim, void your policy back to the start, and keep any premiums you have paid. This can also make it very difficult to get any type of insurance in the future. Honesty is always the best policy.
Can I get private medical insurance if I have a history of cancer?
If you have an active or recent history of cancer, it will be excluded from a new PMI policy. Private medical insurance is designed to cover conditions that arise after you join, not provide treatment for pre-existing cancer. However, you can still get a policy to cover you for other new, unrelated acute conditions. Many policies also include an 'NHS Cancer Cash Benefit,' which pays you a fixed sum if you choose to have cancer treatment on the NHS, even for a pre-existing cancer.
Is high blood pressure (hypertension) a pre-existing condition?
Yes, if you were diagnosed with it, or were prescribed medication for it, before your policy began, it is a pre-existing condition. It is also a chronic condition, which means the ongoing monitoring and management (GP check-ups, prescriptions) would not be covered by a standard private medical insurance UK policy anyway. However, the policy would still cover you for new, acute conditions that are not related to your hypertension.
Navigating the complexities of private medical insurance with a pre-existing condition doesn't have to be a solo journey. The right advice can make all the difference, ensuring you get a policy that provides genuine value and security.
