Key takeaways
- An acute condition is a disease, illness, or injury that is likely to respond quickly to treatment and lead to a full recovery. Examples include a hernia, cataracts, joint pain requiring a replacement, or appendicitis.
- A chronic condition is a disease, illness, or injury that has one or more of the following characteristics: it needs long-term monitoring, it has no known cure, it is likely to recur, or it requires ongoing management. Examples include diabetes, asthma, arthritis, and the vast majority of rare genetic disorders.
- Prevalence: It is estimated that 1 in 17 people in the UK will be affected by a rare disease at some point in their lives. That's over 3.5 million people, according to data from organisations like Genetic Alliance UK.
- Diversity: There are over 7,000 known rare diseases, with more being discovered each year. Around 80% of these are genetic in origin.
- Your policy being cancelled: The insurer can void the policy from the start, leaving you with no cover.

Specialist advice and what to do if family history or diagnosis complicates your application
A family history of a rare condition or a pre-existing diagnosis can feel like a significant barrier when applying for private health insurance. Many people worry it means an automatic rejection or unaffordable premiums. The reality is more nuanced. While it does complicate the application, it doesn't necessarily close the door on valuable private health cover.
The key is to approach the process with open eyes, complete honesty, and the support of a specialist broker. Insurers will need to carefully assess the risk, and your application will be scrutinised more closely. This guide will walk you through exactly what insurers look for, what you must declare, and what cover is realistically possible.
Understanding Private Medical Insurance (PMI) in the UK
Before diving into the specifics of rare conditions, it's vital to understand the fundamental purpose of private medical insurance in the UK.
PMI is designed to cover acute conditions that arise after your policy begins.
- An acute condition is a disease, illness, or injury that is likely to respond quickly to treatment and lead to a full recovery. Examples include a hernia, cataracts, joint pain requiring a replacement, or appendicitis.
- A chronic condition is a disease, illness, or injury that has one or more of the following characteristics: it needs long-term monitoring, it has no known cure, it is likely to recur, or it requires ongoing management. Examples include diabetes, asthma, arthritis, and the vast majority of rare genetic disorders.
This distinction is the single most important concept in UK private health insurance.
Crucially, standard private health insurance policies do not cover chronic conditions or pre-existing conditions. A pre-existing condition is any illness or injury you had symptoms of, received advice for, or sought treatment for before your policy started.
Why Are Chronic and Pre-existing Conditions Excluded?
Insurers base their premiums on the statistical risk of a person needing treatment for unforeseen, acute medical issues in the future. Covering known, ongoing conditions would be like insuring a house that is already on fire. The costs would be astronomical and unsustainable, making insurance unaffordable for everyone. The NHS exists to provide comprehensive care for all, including the long-term management of chronic conditions, regardless of your ability to pay.
PMI works alongside the NHS, offering a route to faster diagnosis and treatment for new, acute problems.
What is a 'Rare Condition' and How Do Insurers View It?
In the UK and Europe, a condition is defined as 'rare' if it affects fewer than 1 in 2,000 people. While individual conditions are rare, collectively they are common.
- Prevalence: It is estimated that 1 in 17 people in the UK will be affected by a rare disease at some point in their lives. That's over 3.5 million people, according to data from organisations like Genetic Alliance UK.
- Diversity: There are over 7,000 known rare diseases, with more being discovered each year. Around 80% of these are genetic in origin.
For an insurer, a rare condition presents a significant underwriting challenge. The lack of extensive data makes it difficult to predict the condition's progression, potential complications, and associated treatment costs. This uncertainty means underwriters must be cautious. They will view a diagnosed rare condition as a pre-existing and chronic condition, which means it will be excluded from cover.
Navigating the Application Process with a Rare Condition or Family History
When you apply for PMI, the insurer needs to understand your medical history to assess your risk. This is done through a process called underwriting. There are two main types.
Types of Medical Underwriting
| Underwriting Type | How It Works | Best For... |
|---|---|---|
| Moratorium (MOR) | You don't declare your full medical history upfront. Instead, the policy automatically excludes any condition you've had symptoms of, or sought advice/treatment for, in the 5 years before the policy start date. | People with a clean bill of health or minor past issues who want a quick application process. |
| Full Medical Underwriting (FMU) | You complete a detailed health questionnaire, declaring your entire medical history, including any family history of serious illness. The insurer then decides what they will and will not cover from the outset. | People with pre-existing conditions or a complex family history. It provides absolute clarity on what's covered from day one. |
For anyone with a diagnosed rare condition or a significant family history of one, Full Medical Underwriting (FMU) is almost always the recommended path. It forces a clear and transparent conversation with the insurer, resulting in a policy where you know exactly where you stand. There are no grey areas or future disputes about what was or wasn't a pre-existing condition.
The Golden Rule: Always Be Honest
It can be tempting to omit details about your health or family history, fearing it will lead to a rejection or higher price. This is a mistake. Non-disclosure can lead to:
- Your policy being cancelled: The insurer can void the policy from the start, leaving you with no cover.
- A claim being rejected: You could undergo private treatment believing you are covered, only to have the claim denied, leaving you with a bill for tens of thousands of pounds.
- Difficulty getting insurance in the future: Having a policy cancelled for non-disclosure is a major red flag for all other insurers.
Insurers have access to shared industry databases and can request your medical records (with your consent) when you make a claim. Any inconsistencies will be found. Honesty is not just the best policy; it's the only policy.
Will My Rare Condition Be Covered by Private Health Insurance?
This is the core question, and the answer depends entirely on your situation. Let's break it down into three common scenarios.
Scenario 1: You Have a Diagnosed Rare Condition
If you have already been diagnosed with a rare condition, it will be treated as a pre-existing condition.
- Outcome: The condition itself, and any related symptoms or complications, will be permanently excluded from your policy.
For example, if you have Ehlers-Danlos Syndrome (EDS), a group of inherited disorders that affect connective tissues, your policy would have an exclusion for EDS. This means it would not cover consultations with a rheumatologist for joint hypermobility, physiotherapy for related pain, or treatment for any direct complications of the condition.
However, you would still be covered for new, unrelated acute conditions, like developing gallstones or needing a hernia repair.
Scenario 2: You Have a Family History of a Rare Genetic Condition
This is more complex. Under Full Medical Underwriting, you must declare if a close blood relative (parent, sibling) has a serious hereditary condition, such as Huntington's Disease, a BRCA gene mutation, or certain types of muscular dystrophy.
The insurer's decision will depend on several factors:
- The specific condition and its inheritance pattern.
- The likelihood of you developing the condition.
- Whether you have undergone genetic testing yourself.
Possible Outcomes:
- A Specific Exclusion: The most likely outcome. The insurer will place an exclusion on your policy for the specific rare condition and any related treatments. For example, if your mother has Huntington's Disease, your policy will likely exclude all investigations and treatment for Huntington's.
- A Premium Loading: In some rare instances, if the risk is deemed manageable but increased, the insurer might offer cover with a higher premium. This is uncommon for serious genetic conditions.
- No Impact: If the risk is considered very low, it might not affect your application, but this is also rare for significant hereditary diseases.
Working with an expert PMI broker like WeCovr is invaluable here. We can discreetly approach different insurers on your behalf to understand how they would likely treat your specific family history, helping you find the provider with the most favourable terms.
Scenario 3: You Develop a Rare Condition After Your Policy Starts
This scenario is where private medical insurance can be incredibly valuable. If you are healthy when you take out your policy and later develop symptoms of a new, unknown condition, PMI is there to help.
The Patient Pathway with PMI
| Stage | What Happens with PMI | What Happens with NHS |
|---|---|---|
| 1. Initial Symptoms | You use the Digital GP service for an instant consultation. You get an open referral to see a specialist. | You wait for a GP appointment, then get referred to a specialist, which can take many weeks or months. |
| 2. Specialist Consultation | Your PMI policy covers a prompt consultation with a private consultant specialist (e.g., a neurologist, geneticist). | You are placed on an NHS waiting list for a first consultant appointment. |
| 3. Diagnostics | Your policy covers the cost of advanced diagnostic tests like MRI scans, CT scans, and genetic tests to get a quick, definitive diagnosis. | You are placed on NHS waiting lists for these diagnostic tests, which can add further delays. |
| 4. Diagnosis Confirmed | The specialist confirms a diagnosis of a rare, chronic condition. | The diagnosis is confirmed, often after a much longer wait. |
| 5. Handover to NHS | Once the condition is diagnosed as chronic, your private cover for it ends. Your ongoing care, management, and treatment are handed over to the NHS. | The NHS manages your ongoing care from the point of diagnosis. |
The key benefit of PMI in this scenario is speed. It can dramatically shorten the "diagnostic odyssey" that many people with rare diseases face. Getting a diagnosis quickly can be critical for accessing the right NHS care pathway, connecting with support groups, and gaining peace of mind. While PMI won't cover the long-term chronic care, its role in getting you to that point faster can be life-changing.
What Can PMI Offer If the Rare Condition Itself Isn't Covered?
Even with a full exclusion for a pre-existing rare condition, a private health insurance policy can still offer tremendous value. You are not just your condition. You can still suffer from all the common acute ailments that affect everyone else.
Here’s what a good PMI policy provides:
- Fast-Track Treatment for Unrelated Acute Conditions: This is the main benefit. If you need a hip replacement, cataract surgery, or cancer treatment (for a new cancer, not related to a pre-existing genetic condition), PMI lets you bypass NHS waiting lists and receive treatment in a private hospital of your choice. According to NHS England data, the median waiting time for elective treatment can be many months, a wait you can avoid with PMI.
- Comprehensive Cancer Cover: Most top-tier policies offer extensive cancer cover, including access to drugs and treatments that may not be available on the NHS due to funding decisions.
- Value-Added Services: Modern PMI policies are packed with benefits you can use every day, even when you're not ill:
- 24/7 Digital GP: Speak to a GP via phone or video call, often within minutes. This is incredibly convenient and reduces the burden on your local surgery.
- Mental Health Support: Access to therapy sessions, counselling hotlines, and mental wellbeing apps. Living with a rare condition can take a toll on mental health, and this support can be a lifeline.
- Second Medical Opinion Services: If you have concerns about an NHS diagnosis or treatment plan (even for your excluded condition), some policies allow you to get a second opinion from a world-leading expert.
- Wellness and Lifestyle Benefits: Many insurers offer discounts on gym memberships, fitness trackers, and health screenings to encourage a healthy lifestyle.

Practical Steps and Wellness Tips
Living with the uncertainty of a rare condition or a family history can be stressful. Taking proactive steps can empower you.
Managing Your Health Application
- Gather Your Information: Before speaking to a broker, collate all relevant medical details: names of conditions, dates of diagnosis, specialists seen, treatments received, and any genetic test results.
- Contact a Specialist Broker: Don't go direct to an insurer. An expert will save you time, stress, and potentially money by finding the right policy for your unique circumstances.
- Be Transparent: Commit to full honesty on your application.
- Review Exclusions Carefully: When you receive your policy documents, read the exclusions page carefully. Make sure you understand exactly what is and isn't covered.
Thriving with a Rare Condition: Wellness & Lifestyle
Whether your condition is covered by insurance or not, focusing on your overall wellbeing is paramount.
- Diet: A balanced, nutrient-rich diet is your foundation. While there's no magic diet for most rare conditions, focusing on whole foods, lean proteins, and healthy fats can support your immune system and energy levels. Using an app like CalorieHero, which WeCovr provides to clients, can help you track your nutrition and ensure you're meeting your body's needs.
- Activity: Consult your specialist or a physiotherapist about safe and beneficial forms of exercise. Gentle activities like swimming, yoga, or walking can improve mobility, reduce pain, and boost mental health.
- Sleep: Prioritise a consistent sleep schedule. Quality sleep is essential for cellular repair, hormone regulation, and managing chronic pain and fatigue.
- Mental Resilience: Connect with support organisations like Rare Disease UK. Sharing experiences with others who understand can be incredibly powerful. Practice mindfulness, meditation, or journaling to manage stress.
- Travel: If you have a rare condition, plan travel carefully. Ensure you have enough medication, a letter from your doctor, and comprehensive travel insurance that specifically covers your pre-existing condition (this is different from PMI).
Private medical insurance is not a magic bullet for rare conditions, but it is a powerful tool. By understanding its purpose and its limitations, you can secure valuable cover that provides peace of mind, rapid access to care for a host of other health issues, and a wealth of benefits to support your overall wellbeing.
