Navigating private medical insurance in the UK can feel complex, especially concerning pre-existing conditions. As an FCA-authorised expert broker that has helped arrange over 800,000 policies, WeCovr is here to provide clarity. This guide demystifies how insurers treat past medical issues and what your options are.
Understanding how insurers assess your health is the single most important step in choosing the right private health cover. This process, known as underwriting, determines what is and isn't covered. The method you choose—or that is chosen for you—has significant long-term implications for your policy.
Let's break down the key concepts, starting with the most fundamental question.
In the simplest terms, a pre-existing condition is any disease, illness, or injury for which you have experienced symptoms, received medication, or sought advice or treatment before the start date of your policy.
This definition is broad and can include:
The core principle of private medical insurance in the UK is that it is designed to cover new, eligible, acute conditions that arise after you join. It is not designed to cover the ongoing management of long-term (chronic) conditions or issues that were already present.
Understanding this distinction is key to grasping what private medical insurance (PMI) will and will not cover.
| Condition Type | Description | Examples | PMI Cover? |
|---|---|---|---|
| Acute | A condition that is sudden in onset, short in duration, and is expected to respond quickly to treatment, leading to a full recovery. | Broken bones, appendicitis, hernias, cataracts, most infections. | Yes, this is what PMI is for. |
| Chronic | A condition that is long-lasting, has no known cure, and requires ongoing management or monitoring. | Diabetes, arthritis, asthma, Crohn's disease, high blood pressure. | No, ongoing management is not covered. |
Important Note: Even if you have a chronic condition, you can still get immense value from a PMI policy. The policy would not cover your chronic diabetes management, for example, but it would cover you for an unrelated acute condition like gallbladder removal, allowing you to bypass lengthy waiting lists. According to NHS England data, the median waiting time for consultant-led elective care was over 14 weeks in mid-2024, a figure that private cover helps you avoid.
Underwriting is how an insurer assesses your medical history to determine the terms of your policy. In the UK, there are two main methods.
This is the most common type of underwriting for individual and small business policies because it's quick and simple to set up.
Example: Sarah and her Eczema
Sarah took out a policy with moratorium underwriting on 1st November 2025. She had used a cream for mild eczema in 2023.
Pros of Moratorium: ✅ Fast and easy application process. ✅ Less intrusive, no need for a long medical form. ✅ Conditions you had over five years ago are typically covered from day one. ✅ The possibility for recent conditions to become covered in the future.
Cons of Moratorium: ❌ Lack of certainty. You may not know if a condition is covered until you make a claim. ❌ Claims can take longer to process due to medical history checks. ❌ "Related conditions" can be a grey area, potentially leading to disputes.
With FMU, the insurer gathers all your medical information at the start to make a clear and final decision on cover.
Example: David and his Back Pain
David has a history of lower back pain and has seen a chiropractor a few times in the past. He chooses Full Medical Underwriting.
Pros of Full Medical Underwriting: ✅ Complete clarity and certainty from day one. You know exactly what is and isn't covered. ✅ Faster and smoother claims process, as the underwriting is already done. ✅ No ambiguity about "related conditions".
Cons of Full Medical Underwriting: ❌ Longer, more detailed application process. ❌ Exclusions are often permanent, with no chance of being reviewed. ❌ You must have a good recall of your medical history.
| Feature | Moratorium Underwriting | Full Medical Underwriting (FMU) |
|---|---|---|
| Application Process | Quick and simple, no health form. | Detailed health questionnaire required. |
| Initial Certainty | Low. Cover for past issues is uncertain. | High. Exclusions are stated clearly in your policy. |
| Claims Speed | Can be slower as insurer investigates your history. | Generally faster as underwriting is pre-approved. |
| Pre-Existing Conditions | Excluded for 2 years, then potentially covered if you remain symptom-free. | Usually excluded permanently via an endorsement. |
| Best For... | People with few or no recent medical issues, or those who value a quick start. | People who want absolute certainty, or have a complex medical history they wish to clarify upfront. |
An expert PMI broker, like the team at WeCovr, can walk you through the pros and cons based on your personal health history, helping you choose the path that offers the best protection and value for you.
The private medical insurance UK market is constantly evolving. Here are the key trends we are seeing in how insurers underwrite policies.
For the 7 million+ people in the UK with some form of private health cover, switching providers used to be a major headache. If you had developed and claimed for a condition with your old insurer, a new insurer would treat it as a pre-existing condition and exclude it.
Now, most major insurers offer Continued Personal Medical Exclusions (CPME) underwriting. This allows you to switch to a new provider on equivalent terms, carrying over the cover for conditions you've already had. It's a game-changer for ensuring a competitive market and is something a good broker can manage for you seamlessly.
Insurers have recognised the growing need for mental health support. While pre-existing and chronic mental health conditions (like bipolar disorder or long-term depression) remain largely excluded from cover for treatment, many policies are now including:
PMI is no longer just about paying for surgery. Insurers are competing to be a holistic health partner. This means your policy is likely to include a suite of benefits designed to keep you healthy, such as:
As a WeCovr client, you get complimentary access to our AI-powered nutrition app, CalorieHero, to help you manage your diet and achieve your health goals. We also offer discounts on other insurance products, such as life or income protection, when you purchase a PMI policy.
A common misconception is that if you have a chronic condition, PMI is not for you. This is incorrect. While your policy won't pay for the routine management of your diabetes, arthritis, or asthma, it provides an invaluable safety net for everything else.
Imagine you have well-managed high blood pressure (a chronic condition). One day, you develop severe abdominal pain and your GP suspects a hernia.
Your PMI policy works in parallel with the NHS, giving you control, speed, and choice when you are diagnosed with a new, acute condition, regardless of any chronic conditions you may already live with.
Managing a chronic condition effectively not only improves your quality of life but can also reduce the risk of developing new, acute complications. For example, individuals with diabetes can significantly lower their risk of related cardiovascular events through regular physical activity. Even 30 minutes of brisk walking, five days a week, can make a substantial difference. Combine this with a balanced diet—something our CalorieHero app can help you track—to maintain a healthy weight and support your overall wellbeing.

| Scenario | The Situation | Underwriting Choice | The Outcome |
|---|---|---|---|
| Amelia, 28 | Fit and healthy, but had physiotherapy for a running-related ankle sprain 3 years ago. | Moratorium | Her ankle is excluded for the first 2 years. She remains symptom-free. After 2 years, her ankle becomes eligible for cover. A year later, she develops a new knee problem, which is covered immediately. |
| Ben, 52 | Has a history of gout and has taken medication for high cholesterol for several years. He wants no surprises. | Full Medical Underwriting (FMU) | He declares both conditions. The insurer applies permanent exclusions for "gout and hypercholesterolemia". Ben is happy with this, as he knows any other new, unrelated condition (like a future need for a cataract operation) will be covered without question. |
| Chloe, 45 | Has a PMI policy with Insurer A. She had a claim for sinus surgery two years ago. She sees a better deal with Insurer B. | Continued Personal Medical Exclusions (CPME) | Her broker, WeCovr, arranges a CPME switch. Insurer B takes her on, honouring the cover she had with Insurer A. This means any future sinus issues will still be covered, and she benefits from a lower premium. |
