Navigating the world of private medical insurance (PMI) in the UK can feel complex, especially when it comes to past health issues. At WeCovr, an FCA-authorised broker that has helped arrange over 900,000 policies, we believe in clarity. This guide explains exactly how insurers handle pre-existing conditions.
Understanding how private health cover treats conditions you've had in the past is the single most important step in choosing the right policy. Get this wrong, and you could face the disappointment of a rejected claim just when you need support the most.
The entire system revolves around a fundamental principle: standard UK private medical insurance is designed to cover new, unforeseen, and acute medical conditions that arise after your policy begins. It is not designed to cover the ongoing management of long-term (chronic) illnesses or to treat conditions you already have.
This distinction shapes every aspect of your policy, from the questions you're asked when you apply to the way claims are assessed. The three key concepts you'll need to master are:
Let's break down each of these pillars to give you the confidence to choose the right private medical insurance in the UK.
In the simplest terms, a pre-existing condition is any illness, injury, or symptom for which you have sought medical advice, received treatment, or experienced symptoms before the start date of your PMI policy.
It doesn't matter if you received a formal diagnosis or not. If you went to your GP with persistent back pain six months before taking out cover, that back pain is a pre-existing condition.
Common Examples of Pre-Existing Conditions:
Insurers typically look back at your medical history over the last five years, but this can vary. The key takeaway is that if it happened before your policy started, it's "pre-existing."
It's vital to understand the difference between acute and chronic conditions, as this is the bedrock of the UK PMI market.
| Condition Type | Definition | PMI Coverage | Example |
|---|---|---|---|
| Acute | A disease, illness, or injury that is likely to respond quickly to treatment and lead to a full recovery. It has a sudden onset and is short-lived. | Covered (if it's a new condition that arises after your policy starts). | A broken bone, appendicitis, a cataract, or a hernia requiring surgery. |
| Chronic | A disease, illness, or injury that is long-term. It may have no known cure, requires ongoing management, and can involve periods of relapse and remission. | Not Covered | Diabetes, Crohn's disease, multiple sclerosis, rheumatoid arthritis, and most forms of hypertension. |
The NHS excels at managing chronic conditions, and this is its primary role. Private medical insurance complements the NHS by providing fast access to diagnosis and treatment for new, acute issues, helping you bypass NHS waiting lists. According to NHS data, the number of people in England waiting for routine hospital treatment remains in the millions, highlighting the value of PMI for acute care.
When you apply for health insurance, you enter into a contract based on good faith. Under the Consumer Insurance (Disclosure and Representations) Act 2012, you have a legal duty to take "reasonable care" not to make a misrepresentation to your insurer.
In plain English: you must be completely honest.
Withholding information about a past health condition might seem tempting, perhaps to get a lower premium or avoid an exclusion. However, this is a high-risk strategy with serious consequences.
If you make a claim and the insurer discovers a pre-existing condition that you failed to declare, they can:
It is never worth the risk. A policy with a clear, upfront exclusion for a condition you know about is far more valuable than a policy that could be cancelled when you need it most.
"Underwriting" is the process an insurer uses to assess your health and risk profile to decide the terms of your policy. For pre-existing conditions, there are two main methods in the UK.
Choosing between them is one of the biggest decisions you'll make. An expert PMI broker, like the team at WeCovr, can provide personalised guidance on which path is best for your unique circumstances.
This is the most common type of underwriting for individual and family policies because it's quick and simple.
How it works: With a moratorium policy, you do not complete a health questionnaire upfront. Instead, the policy automatically excludes any medical condition you've had symptoms, treatment, or advice for in the 5 years before the policy began.
This exclusion isn't necessarily permanent. The condition may become eligible for cover later on if you meet two criteria:
Example in Practice:
Pros and Cons of Moratorium Underwriting
| Pros | Cons |
|---|---|
| Fast & Simple Application: No lengthy health forms to fill out. | Lack of Certainty: You don't know for sure what's covered until you claim. |
| Less Intrusive: You don't have to recall and list your entire medical history. | Potential for Claim Delays: Insurers will need to investigate your medical history when you make a claim, which can slow things down. |
| Exclusions Can Be Overturned: Conditions can automatically become eligible for cover after the 2-year period. | The "Reset" Clock: A minor symptom or GP visit can restart the 2-year waiting period for that condition. |
This is a more traditional method of underwriting.
How it works: With FMU, you complete a detailed health questionnaire as part of your application. You must declare all of your past medical conditions, treatments, and consultations. The insurer's underwriting team will then review your medical history.
Based on your answers, they will issue policy documents that explicitly state any specific exclusions that will apply to your cover. These exclusions are usually permanent.
Example in Practice:
Pros and Cons of Full Medical Underwriting
| Pros | Cons |
|---|---|
| Total Certainty: You know exactly what is and isn't covered from day one. | Lengthy Application Process: The health questionnaire can be long and detailed. |
| Faster Claims Process: As exclusions are pre-agreed, claims for eligible conditions are often processed more quickly. | More Intrusive: Requires you to provide detailed personal health information upfront. |
| No "Grey Areas": Avoids the uncertainty of a moratorium investigation at the point of claim. | Exclusions are Often Permanent: It is harder to get an FMU exclusion removed than to pass a moratorium period. |
| Feature | Moratorium Underwriting | Full Medical Underwriting (FMU) |
|---|---|---|
| Application Process | Quick and simple, no health forms. | Requires a detailed health questionnaire. |
| Upfront Certainty | Low. You only find out if a condition is covered when you claim. | High. Exclusions are clearly stated on your policy certificate from the start. |
| Speed of Policy Setup | Very fast, often instant. | Slower, as it requires assessment by an underwriter. |
| Claim Process | Potentially slower, as insurer may need to request medical records to check for pre-existing history. | Generally faster for eligible conditions, as exclusions are already defined. |
| Exclusions | Automatically applied to conditions from the last 5 years. Can "drop off" after a 2-year clear period. | Specifically listed on your policy. Usually permanent, but can sometimes be reviewed. |
| Best For... | People with a clean bill of health or very minor past issues who prefer a quick start. | People with a complex medical history who want absolute clarity on what is and isn't covered. |
Many people with existing PMI policies worry about switching providers, fearing they will lose cover for conditions that have developed while they were insured. This is a valid concern, but there is a specific underwriting method to handle it.
Continued Personal Medical Exclusions (CPME) Underwriting:
This is the best option for anyone looking to switch their private health cover. With CPME, your new insurer agrees to replicate the underwriting terms of your previous policy.
Navigating a CPME switch can be complex. Insurers have different rules and appetites for taking on new members this way. This is where an independent PMI broker like WeCovr is invaluable. We can compare the market to find a provider who will offer you CPME terms, ensuring your continuity of cover is protected.
Even if you have pre-existing conditions that are excluded from treatment cover, a modern PMI policy offers a wealth of benefits to help you manage your overall health and wellbeing. These are often available to all members, regardless of their medical history.
By using these benefits, you can take control of your health, potentially reducing the impact of your pre-existing conditions and lowering your risk of developing new acute problems.
The information in this guide highlights the many variables involved in securing the right PMI policy. The decision between Moratorium and Full Medical Underwriting alone can have a huge impact on your future cover.
