As an FCA-authorised broker that has helped arrange over 900,000 policies, WeCovr understands the biggest question for UK consumers exploring private medical insurance is about their medical history. This guide cuts through the confusion, explaining exactly how private health cover treats conditions you already have.
Navigating the world of private medical insurance (PMI) can feel complex, especially when you have a past or current health condition. The single most common question we hear is: "Will my pre-existing condition be covered?"
The short, straightforward answer is that standard UK private medical insurance is designed to cover new, unforeseen, acute conditions that arise after your policy begins. It does not, as a rule, cover pre-existing or chronic conditions.
But that is not the end of the story. Understanding the rules, the types of underwriting, and your options is crucial. In this definitive 2026 guide, we will break down everything you need to know about pre-existing conditions, helping you find the right path forward for you and your family's health.
Before we go any further, let's define our terms in plain English.
A pre-existing condition is any illness, injury, or symptom for which you have experienced symptoms, sought medical advice, received a diagnosis, or taken medication before the start date of your health insurance policy.
This definition is broad and can include:
It’s also vital to distinguish between acute and chronic conditions. This is the bedrock of how UK PMI works.
| Feature | Acute Condition | Chronic Condition |
|---|---|---|
| Definition | A disease or illness that is likely to respond quickly to treatment and lead to a full recovery. | A disease, illness, or injury that has one or more of the following characteristics: it needs ongoing or long-term monitoring, requires palliative care, has no known cure, or is likely to come back. |
| PMI Coverage | Covered. This is what PMI is for. | Not Covered. This is managed by the NHS. |
| Examples | Hernia, appendicitis, cataracts, joint replacement due to injury, most cancers (that are not pre-existing). | Diabetes, asthma, arthritis, Crohn's disease, high blood pressure (hypertension). |
Private health cover exists to provide fast access to treatment for new acute conditions, complementing the fantastic work the NHS does in managing long-term, chronic care for the nation.
The fundamental principle of insurance is to protect against unforeseen future risk. Think of it like car insurance: you can't buy a policy to cover an accident that has already happened. Health insurance operates on the same logic.
Insurers calculate premiums based on the statistical likelihood of a person needing treatment for a new condition in the future. If they were to cover known, existing health problems, the costs would be astronomical. Premiums would become unaffordable for the vast majority of people, and the entire model would collapse.
Excluding pre-existing and chronic conditions ensures that:
With the NHS waiting list in England standing at 7.54 million in September 2023, according to NHS England data, and projections suggesting significant lists will persist into 2026, the value of PMI for new, eligible conditions has never been clearer.
"Underwriting" is the process an insurer uses to assess your application and decide what they will and will not cover. When it comes to pre-existing conditions, there are two main methods used in the UK. Understanding the difference is essential.
With Full Medical Underwriting, you complete a detailed health questionnaire as part of your application. You must declare your full medical history, including any conditions, consultations, and treatments you've ever had.
Real-life example: Sarah applies for a policy with FMU. She declares that she had physiotherapy for shoulder pain two years ago. The insurer places a specific exclusion on her policy for "any treatment related to her right shoulder". Six months later, she develops a new problem with her knee. This is fully covered because it's an unrelated, new condition.
Moratorium underwriting is the most common type in the UK because it's much simpler to set up. There is no initial medical questionnaire to complete.
Real-life example: David takes out a moratorium policy. Three years before joining, he saw his GP for knee pain. In his first year of the policy, his knee is fine. In the second year, it remains fine. After two full, continuous years on the policy with no knee-related symptoms, medication, or advice, his knee becomes eligible for cover for any new problems that might arise.
| Feature | Full Medical Underwriting (FMU) | Moratorium Underwriting (MORI) |
|---|---|---|
| Application Process | Long questionnaire, detailed medical history required. | Quick setup, no initial health questions. |
| Initial Certainty | High. You get a list of specific exclusions from the start. | Low. Exclusions are general; you find out at the point of a claim. |
| Cover for Past Conditions | Generally excluded forever, but some very minor/old conditions might be accepted. | Conditions can become eligible for cover after a 2-year trouble-free period. |
| Best For | People who want absolute clarity from day one and have a complex medical history they want defined. | People with few or no recent health issues who want a quick and easy application. |
An expert PMI broker, like the team at WeCovr, can talk you through which option is best for your specific circumstances, ensuring you make an informed choice.
While the general rule is no, there are scenarios where cover for a pre-existing condition can be gained.
The Moratorium Pathway: As explained above, this is the most common way. If you remain completely symptom-free and require no advice or treatment for a condition for two continuous years after your policy starts, it can be added to your cover. This offers a clear pathway for older, resolved issues to eventually become eligible.
Negotiation with Full Medical Underwriting: In some rare cases with FMU, if a condition was very minor, occurred a long time ago, and has been fully resolved with no chance of recurrence, an insurer might agree to cover it. More likely, they may offer to cover it with an increased premium (a "premium loading") or simply apply the exclusion anyway. This is not common but can be explored by a skilled broker.
This is a critical point that often trips people up. Your policy will not just exclude your declared pre-existing condition, but also any condition that is medically related to it.
For example, if you have a pre-existing exclusion for high blood pressure (hypertension):
This is why complete honesty during the application is so important.
Having a medical history doesn't mean you can't get valuable private medical insurance. It's about setting the right expectations and choosing the right strategy.
Be Completely Honest: The worst thing you can do is hide a medical condition. Non-disclosure can lead to your insurer cancelling your policy and declining all claims, leaving you with a large medical bill and making it harder to get insurance in the future. Always be upfront.
Choose the Right Underwriting: If your medical history is straightforward and any issues were more than five years ago, a moratorium policy is often a great, simple choice. If you have a more complex or recent history, FMU can provide the clarity you need, even if it means accepting specific exclusions.
Use an Expert Broker: This is arguably the most important step. A specialist private medical insurance broker like WeCovr works for you, not the insurer. We know the entire UK market inside out. We understand the subtle differences in how each provider (like Bupa, AXA Health, Aviva, Vitality) views different conditions. We can:
Consider a Health Cash Plan: If your main goal is to get money back for routine expenses, a health cash plan could be a good supplement or alternative. These plans are not PMI. They provide a set amount of cash back per year for things like dental check-ups, eye tests, physiotherapy, and specialist consultations. Crucially, they typically accept everyone, regardless of pre-existing medical conditions, for these routine benefits.
Focus on the Value PMI Does Provide: Even with exclusions for your past conditions, a PMI policy is hugely valuable. It gives you protection against the financial and emotional stress of waiting for treatment for a whole range of future acute conditions, from cancer care and surgery to diagnostic scans and mental health support.
The world of health insurance is evolving. In 2026, we're seeing a major shift away from just being there when you're ill, towards helping you stay well in the first place.
Insurers are increasingly integrating wellness programmes and rewards into their policies. These programmes encourage healthy living by offering discounts on gym memberships, fitness trackers, healthy food, and even cinema tickets for staying active.
This proactive approach is a win-win:
At WeCovr, we embrace this philosophy. That’s why all our clients who take out a private medical or life insurance policy receive complimentary access to CalorieHero, our exclusive AI-powered calorie and nutrition tracking app, to support their health and wellness journey. Furthermore, our clients often benefit from discounts on other insurance products, such as life or income protection cover, when they arrange their PMI through us.
Regardless of your insurance status, taking control of your health is the best investment you can make. It can help manage existing conditions and prevent new ones from developing.
Taking these steps can have a direct impact on your health insurance. For those on a moratorium policy, a healthy lifestyle might help you pass the two-year period without symptoms, allowing a condition to become covered.
