As an FCA-authorised broker that has helped arrange over 800,000 policies, WeCovr knows that navigating the world of private medical insurance in the UK can be complex, especially when you have a health history. This guide demystifies how pre-existing conditions are treated, what’s covered, and your options.
Understanding the relationship between pre-existing conditions and private health insurance is the single most important step in choosing the right policy. It prevents future disappointment and ensures you know exactly what you are paying for.
The fundamental principle of standard UK private medical insurance (PMI) is that it's designed to cover new, acute medical conditions that arise after your policy begins. It is not designed to cover conditions you already have, nor is it for the long-term management of chronic illnesses.
This guide will walk you through everything you need to know, providing clarity and confidence as you explore your private healthcare options.
In the context of UK private health insurance, a pre-existing condition is any disease, illness, or injury for which you have experienced symptoms, received medication, sought advice, or undergone treatment before the start of your policy.
This definition is broad and can include:
Insurers typically look back at your medical history over the last five years, but some policies may consider your entire history for certain conditions.
Understanding this distinction is key to grasping what private medical insurance is for. The UK system relies on a partnership between the NHS and private providers. The NHS excels at managing long-term, chronic conditions, while PMI offers speed and choice for treatable, short-term issues.
Here’s a simple breakdown:
| Feature | Acute Condition | Chronic Condition |
|---|---|---|
| Onset | Typically sudden | Develops over time |
| Duration | Short-term | Long-term or lifelong |
| Treatment Goal | Cure and full recovery | Management of symptoms |
| PMI Cover | Yes, this is the purpose of PMI | No, this is excluded |
| Examples | Hernia repair, cataract surgery, joint replacement, broken bones, appendicitis | Diabetes, asthma, high blood pressure, arthritis, epilepsy, Crohn's disease |
Real-Life Example: Imagine you develop knee pain.
"Underwriting" is the process an insurer uses to evaluate your health and determine the terms of your policy. For individual and small business policies in the UK, there are two main types.
With Full Medical Underwriting, you complete a detailed health questionnaire when you apply. You must disclose your entire medical history, including any pre-existing conditions, treatments, and consultations.
Who is FMU good for? Individuals who want absolute certainty about their cover, especially if they have a complex but well-understood medical history.
Moratorium underwriting is the most common type for personal health insurance policies in the UK because it's simpler and faster to set up.
Who is MORI good for? People who are generally healthy, have had no significant medical issues in the last five years, and prioritise a quick and simple application process.
| Feature | Full Medical Underwriting (FMU) | Moratorium Underwriting (MORI) |
|---|---|---|
| Application Process | Detailed health questionnaire | No initial health questions |
| Speed of Setup | Slower | Fast |
| Clarity at Start | High – you get a list of exclusions | Low – exclusions are general |
| Claim Process | Simpler – cover is pre-agreed | Can be complex – insurer investigates history at claim time |
| Covering Old Conditions | May cover very old conditions upfront | Possible after a 2-year trouble-free period |
| Best For | Peace of mind and certainty | Simplicity and healthy applicants |
The expert team at WeCovr can talk you through these options to help you decide which underwriting method is the best fit for your personal circumstances, ensuring there are no surprises down the line.
Having a pre-existing condition does not mean you can't get private health insurance. It simply means that the condition itself, and often related conditions, will be excluded from cover. You still gain immense value from covering new, unforeseen medical issues.
Here are the practical options available:
This is a popular route. If your pre-existing condition has not required any treatment or advice for several years, a moratorium policy may eventually cover it after the initial two-year waiting period. It's a "wait and see" approach.
If you want clarity, FMU is the way to go. You will have a definite "yes" or "no" on every condition you declare. While this will result in named exclusions, it removes all ambiguity. For many, this peace of mind is invaluable.
This is the "gold standard" of underwriting as it ignores most pre-existing conditions. However, MHD is typically only available to large corporate group schemes (usually 20+ employees) as a staff benefit. It is generally not available for individuals or small family policies due to its high cost and risk to the insurer. Even with MHD, chronic conditions are still usually excluded from long-term cover.
Let's look at how some of the UK's most common pre-existing conditions are typically handled by private medical insurance providers.
| Condition | Typical Insurer Stance | Explanation |
|---|---|---|
| High Blood Pressure (Hypertension) | Excluded | Hypertension is a chronic condition requiring long-term monitoring. While the condition itself won't be covered, some insurers may cover an unrelated acute event, but this can be a grey area. |
| High Cholesterol | Excluded | Like hypertension, this is managed with lifestyle changes or medication and is considered a chronic risk factor. |
| Asthma | Excluded | As a long-term respiratory condition, asthma is considered chronic and will be excluded, especially if you have used an inhaler or had a consultation in the last 5 years. |
| Diabetes (Type 1 or 2) | Excluded | Diabetes requires continuous management and is a classic example of a chronic condition that the NHS manages. It is always excluded from PMI cover. |
| Mental Health (Anxiety, Depression) | Depends on History | If you had a brief episode of mild anxiety years ago, it might be covered after a moratorium period. If you have an ongoing diagnosis or recent treatment, it will be excluded. Many policies now offer some mental health support (like a helpline) as a benefit, even if treatment for pre-existing conditions is excluded. |
| Joint or Back Pain | Excluded if Pre-existing | If you've seen a GP, physio, or chiropractor for back pain in the last 5 years, it will be excluded. However, a new pain in a different joint (e.g., shoulder pain) would be considered a new condition and therefore covered. |
| Previous Cancer | Excluded | Any cancer diagnosed before the policy start date will be excluded, along with any monitoring, check-ups, or treatment related to it. A new, primary cancer that is completely unrelated to the first may be covered, but this is a highly specialist area where broker advice is crucial. |
| Skin Conditions (Eczema, Psoriasis) | Excluded | These are typically chronic, recurring conditions and will be excluded from cover for treatment. |
It can be tempting to omit a minor health issue from your application, but this is a serious mistake. Failing to disclose a pre-existing condition is known as "non-disclosure" and can have severe consequences.
Under the FCA's Consumer Insurance (Disclosure and Representations) Act, you have a duty to take "reasonable care" not to make a misrepresentation. If an insurer discovers you have failed to disclose relevant information, they can:
The golden rule: When in doubt, disclose it. It is always better to have a condition excluded upfront than to have your entire policy cancelled when you need it most.
Even with exclusions for pre-existing conditions, a private medical insurance UK policy offers tremendous benefits and peace of mind. The NHS is a national treasure, but it faces significant pressure. According to recent NHS England data, the waiting list for consultant-led elective care remains at several million, with many people waiting over 18 weeks for treatment.

Here are answers to some of the most common questions our clients ask.
Q1: Can I get private health insurance if I have a pre-existing medical condition? A: Yes, you can absolutely get private health insurance. However, the policy will not cover the pre-existing condition itself or any closely related conditions. The insurance is designed to protect you against new, unforeseen medical issues that arise after your policy begins.
Q2: What is the "2-year rule" for pre-existing conditions in the UK? A: The "2-year rule" refers to moratorium underwriting. Under this system, a condition you had in the 5 years before your policy started is excluded. This exclusion can be lifted if you go for a continuous 2-year period after your policy start date without needing any treatment, medication, or advice for that specific condition.
Q3: Is cancer considered a pre-existing condition by insurers? A: Yes. If you were diagnosed with or treated for cancer before taking out a policy, it is a pre-existing condition and will be excluded from cover. This includes any follow-up consultations, scans, or treatments related to that cancer. A completely new, unrelated primary cancer that develops after the policy starts would typically be covered.
Q4: Will my premiums be higher if I have pre-existing conditions? A: Not necessarily. Since pre-existing conditions are excluded from cover, they don't usually increase the premium. Your premium is primarily calculated based on your age, your location (as hospital costs vary across the UK), the level of cover you choose (e.g., hospital lists, outpatient limits), and your excess.
Understanding how pre-existing conditions affect your private health cover is the first step towards choosing a policy that works for you. While standard policies won't cover what you've already had, they provide invaluable, fast access to treatment for what may lie ahead.
