How private healthcare for existing conditions works and what pre-existing typically means for UK PMI
Understanding how UK private medical insurance (PMI) treats pre-existing conditions is the single most important step in choosing the right policy. The fundamental principle of standard UK PMI is that it is designed to cover new, eligible, acute conditions that arise after your policy has started.
A pre-existing condition is generally defined by insurers as any disease, illness, or injury for which you have experienced symptoms, received medication, advice, or treatment before the start of your policy. This applies whether you have received a formal diagnosis or not.
In short, private health insurance is not designed to cover health issues you already have. Instead, it provides a safety net for unexpected health problems in the future. Chronic conditions, which require ongoing long-term management, are also typically excluded for the same reason.
Let's break down exactly what this means for you and how insurers make these decisions.
What Officially Counts as a Pre-Existing Condition?
Insurers use a clear-cut rule. A condition is considered 'pre-existing' if, in the five years before your policy start date, you have:
- Sought medical advice from a GP, specialist, or other healthcare professional.
- Received treatment, including medication, therapy, or surgery.
- Experienced symptoms, even if you didn't see a doctor about them.
This definition is broad. It could include anything from a bout of back pain you mentioned to your GP two years ago, to a course of antidepressants you took, or even symptoms like recurring headaches that you chose to ignore.
| Scenario | Is it likely pre-existing? | Why? |
|---|---|---|
| You were diagnosed with asthma 10 years ago and use an inhaler. | Yes | You have received a diagnosis and ongoing treatment. |
| You had physiotherapy for a twisted ankle 3 years ago. | Yes | You received treatment for the condition. |
| You experienced occasional stomach cramps but never saw a doctor. | Yes | You experienced symptoms, even without a diagnosis. |
| You broke your arm 6 years ago and have had no issues since. | No | The condition and its treatment occurred more than 5 years ago. |
Understanding this definition is key because it directly impacts how your application is assessed through a process called underwriting.
How UK Insurers Handle Pre-Existing Conditions: Underwriting Explained
Underwriting is the process an insurer uses to evaluate your health and determine the terms of your policy, including what they will and will not cover. For individual PMI in the UK, there are two main types of underwriting.
1. Moratorium Underwriting (The "Wait and See" Approach)
Moratorium (or 'MORI') is the most common type of underwriting for personal health insurance policies. It's popular because it's quick and doesn't require you to fill out a medical questionnaire.
- How it works: Your policy will automatically exclude any pre-existing conditions you've had in the five years leading up to your start date.
- The "Two-Year Rule": Here’s the crucial part. An exclusion on a pre-existing condition may 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.
- The Catch: The two-year clock can reset. If you seek advice for that condition during the two-year waiting period, the clock starts again from that date.
Real-Life Example: Sarah and Her Hay Fever Sarah takes out a policy with moratorium underwriting. She suffers from hay fever and bought an over-the-counter antihistamine spray last summer.
- Year 1 & 2: Her hay fever and any related conditions (like sinus issues) are automatically excluded. During her first spring with the policy, her symptoms return, and she buys another spray. This act of "treatment" resets the two-year clock.
- Year 3 & 4: She must now go two full years from the date she last bought the spray without any symptoms or treatment for her hay fever to be considered for cover.
2. Full Medical Underwriting (The "Clarity from Day One" Approach)
Full Medical Underwriting (FMU) is a more detailed process. You are required to complete a comprehensive health questionnaire as part of your application.
- How it works: You disclose your full medical history. The insurer's underwriting team reviews your answers and decides what, if anything, to exclude from your policy.
- The Result: You receive your policy documents with a clear, personalised list of any specific exclusions. These exclusions are often permanent.
- The Benefit: You have complete certainty from day one about what is and isn't covered. There are no grey areas or waiting periods to worry about at the point of claim.
Real-Life Example: David and His Back Pain David has a history of lower back pain, for which he saw a chiropractor 18 months ago. He chooses a policy with FMU.
- Application: He declares his history of back pain on the application form.
- Insurer's Decision: The insurer reviews his history and places a permanent exclusion on "treatment for the lumbar spine."
- Outcome: David knows he cannot use his PMI for his back. However, if he later develops a completely unrelated shoulder injury, he can claim for it with confidence, knowing his policy is valid.
Moratorium vs. Full Medical Underwriting: Which is Right for You?
| Feature | Moratorium Underwriting (MORI) | Full Medical Underwriting (FMU) |
|---|---|---|
| Application Process | Quick and easy, no health forms. | Longer, requires a detailed medical questionnaire. |
| Initial Exclusions | Automatically excludes conditions from the last 5 years. | Specific exclusions are listed based on your declarations. |
| Clarity | Can be uncertain. You find out what's covered at the point of claim. | Complete clarity from day one. You know your exclusions upfront. |
| Cover for Pre-Existing | Possible after a 2-year symptom/treatment-free period. | Unlikely. Exclusions are usually permanent. |
| Best For... | People with a clean bill of health or minor past issues who want a fast start. | People who want absolute certainty and have a complex medical history to declare. |

The Crucial Difference: Acute vs. Chronic Conditions
This is a distinction that trips up many people. UK private health insurance is built to cover acute conditions, not chronic ones.
-
Acute Condition: An illness or injury that is short-lived, responds to treatment, and from which you are expected to make a full recovery. PMI is designed for this.
- Examples: Appendicitis, a broken leg, cataracts, a hernia, most infections.
-
Chronic Condition: A condition that is long-term, has no known cure, and requires ongoing or periodic management and monitoring. Standard UK PMI does not cover the ongoing management of chronic conditions.
- Examples: Diabetes, hypertension (high blood pressure), asthma, arthritis, Crohn's disease, eczema, multiple sclerosis.
Why are chronic conditions excluded? The insurance model relies on covering unforeseen events. The cost of managing a long-term, predictable condition for thousands of members would make premiums prohibitively expensive for everyone. The NHS is structured to provide this long-term care.
While PMI won't cover the day-to-day management of a chronic condition (e.g., insulin for diabetes, regular check-ups for hypertension), some policies may offer initial cover for the diagnosis of a new condition, even if it turns out to be chronic. Once diagnosed and a management plan is in place, care is typically handed back to the NHS.
Common Pre-Existing Conditions and How Insurers View Them
While every case is unique, here is a general guide to how insurers often treat common pre-existing conditions under FMU. With moratorium, all would be excluded for at least the initial two-year period.
- High Blood Pressure (Hypertension): Almost always excluded. As a chronic condition requiring monitoring, it falls outside the scope of PMI.
- High Cholesterol: Similar to hypertension, this is considered a chronic condition needing management and is therefore excluded.
- Musculoskeletal Issues (e.g., Back Pain, Joint Pain): Very commonly excluded, especially if you have sought treatment in the last 5 years. Insurers are cautious due to the high likelihood of recurrence.
- Mental Health (e.g., Anxiety, Depression): If you have seen a GP, received counselling, or taken medication, it is highly likely to be excluded. Some insurers are starting to offer more comprehensive mental health support, but pre-existing episodes are a standard exclusion.
- Asthma / Eczema / Allergies: These are typically considered chronic and will be excluded if you have had any symptoms or treatment within the 5-year window.
- Cancer: A previous cancer diagnosis will result in a cancer-related exclusion. However, this does not mean you cannot get PMI for other, unrelated future conditions.
- Gastrointestinal Issues (e.g., IBS): Due to their recurring and often long-term nature, these are frequently excluded if declared on an FMU application.
Can I Ever Get Cover for a Pre-Existing Condition?
For most standard policies, the answer is generally no, at least not from the outset. However, there are specific circumstances where cover might become possible:
- Through Moratorium Underwriting: As explained, this is the main route. If you stay symptom-free and treatment-free for two continuous years, your condition may become eligible for cover.
- Switching with Continued Cover: If you already have a private medical insurance policy, you may be able to switch to a new provider on a "Continued Personal Medical Exclusions" (CPME) basis. This means the new insurer agrees to match the exclusions of your old policy, allowing you to keep cover for conditions that developed while you were insured previously. This is a complex process where a broker's help is invaluable.
- Medical History Disregarded (MHD) Schemes: This is the gold standard but is almost exclusively available through large corporate PMI schemes. On an MHD policy, the insurer agrees to ignore all past medical history and cover eligible conditions, whether pre-existing or not. If you have this benefit through your employer, it is extremely valuable.
Switching Insurers with Pre-Existing Conditions
Many people want to switch providers to get a better price, but worry about losing cover for conditions that have developed since they took out their original policy.
This is where specialist underwriting for switchers comes in.
- Continued Moratorium: If your current policy is on a moratorium basis, you can switch to a new provider and your moratorium period continues from your original start date.
- Continued Personal Medical Exclusions (CPME): If you were on an FMU policy, a new insurer can take you on with the exact same exclusions you had before. This means if you were covered for something with your old insurer, you'll be covered for it with your new one.
This allows for seamless switching without being penalised for your loyalty. The team at WeCovr specialises in helping clients switch policies on a CPME basis, ensuring they get a better deal without sacrificing important cover.
What to Do if You Have a Pre-Existing Condition
- Be Completely Honest. When applying with Full Medical Underwriting, you have a "duty of fair presentation." Failing to disclose a condition, symptom, or treatment can lead to a claim being denied or your entire policy being voided. It is never worth the risk.
- Choose Your Underwriting Carefully. If your medical history is complex and you want certainty, FMU is your best bet. If you've been relatively healthy for years, the simplicity of a Moratorium policy might be more appealing.
- Review Your Documents. Once your policy is live, your policy certificate or schedule of cover will list any specific exclusions applied (on an FMU policy). Read it carefully and ensure it matches your understanding.
- Speak to an Independent Broker. This is the most important step. A good broker understands the subtle differences between insurers. Some may be more lenient on certain conditions than others. A broker works for you, not the insurer, and can survey the entire market to find the best possible terms for your specific situation, at no extra cost to you.

Final Thoughts: Managing Your Expectations
The core purpose of private medical insurance in the UK is to give you fast access to high-quality diagnosis and treatment for new, unexpected health problems. It is not a substitute for the NHS, which provides excellent care for emergency services and the management of long-term, chronic conditions.
By understanding that pre-existing conditions are generally excluded, you can set realistic expectations and choose a policy that provides genuine value and peace of mind for the future. An honest conversation with an expert adviser is the best first step to finding cover that truly protects you.
