Navigating the world of private medical insurance (PMI) in the UK can feel like deciphering a complex code. From understanding what's covered to what isn't, and why, it's a journey many embark on to gain peace of mind regarding their health. One of the most crucial, yet often misunderstood, aspects of this journey is underwriting. It's the engine room of your policy, determining what medical conditions an insurer will cover, and equally importantly, what they won't.
If you've ever felt overwhelmed by terms like "Moratorium" or "Full Medical Underwriting," you're not alone. These aren't just jargon; they represent fundamentally different ways your policy is structured, impacting everything from your initial application experience to how your claims are handled down the line. Choosing the wrong underwriting type can lead to significant disappointment and financial unexpectedness precisely when you need your insurance most.
This comprehensive guide aims to demystify UK private health insurance underwriting. We'll deep dive into the two primary types – Moratorium and Full Medical Underwriting – explaining how they work, their pros and cons, and which might be the best fit for your unique circumstances. We'll also touch upon other less common types for completeness and highlight the crucial role that pre-existing conditions play in all underwriting decisions. By the end of this article, you'll be equipped with the knowledge to make an informed decision, ensuring your private health insurance truly meets your needs.
At its heart, underwriting in health insurance is the process by which an insurer assesses the risk associated with covering an individual. It's how they determine the likelihood of you making a claim and, consequently, how they price your premiums and what specific conditions might be excluded from your cover. Think of it as the insurer getting to know your medical history to draw a clear line between what they will and won't pay for.
Why is this necessary? Insurance operates on the principle of shared risk. Without underwriting, everyone would pay the same premium regardless of their health status, making the system unsustainable. For example, someone with a history of serious heart conditions would pay the same as a perfectly healthy individual, which wouldn't be fair or financially viable for the insurer. Underwriting ensures fairness in pricing and clarity regarding coverage.
It's vital to grasp one universal truth in UK private health insurance: policies are designed to cover acute conditions that arise after your policy starts. They are generally not designed to cover conditions you already have (pre-existing conditions) or long-term chronic conditions. Understanding how underwriting handles pre-existing conditions is arguably the single most important element of choosing your PMI policy.
Before we delve into underwriting types, we must firmly establish what constitutes a "pre-existing condition" in the eyes of a health insurer. This is where most misunderstandings and frustrations arise.
A pre-existing condition is generally defined as:
This definition is broad and encompasses more than just a formal diagnosis. If you've had a recurring ache, seen a doctor about a particular symptom, or even taken over-the-counter medication for a persistent issue within that timeframe, it could be considered a pre-existing condition.
Why is this so important? Because standard UK private health insurance policies, regardless of the underwriting type, typically exclude cover for these conditions. This is not about denying care; it's about covering new, unexpected medical events.
Examples of conditions that might be considered pre-existing:
It's paramount to be completely honest and transparent about your medical history during the application process. Failing to disclose a pre-existing condition, even if you believe it's minor, could lead to a claim being denied and your policy becoming invalid. Insurers have the right to request your full medical history from your GP if a claim arises, and discrepancies can be problematic.
Moratorium underwriting is by far the most common type of underwriting used for individual and small business private health insurance policies in the UK. It's popular because it's typically quicker to set up and requires less initial paperwork compared to full medical underwriting.
With moratorium underwriting, you generally do not need to declare your full medical history upfront when you apply. Instead, the insurer applies an automatic exclusion period (the "moratorium") to any pre-existing condition you've had during a specified look-back period (usually the last 5 years). This moratorium period is typically 2 years from the start date of your policy.
During this 2-year moratorium period:
After the 2-year moratorium period:
If you do experience symptoms or require treatment for that condition during the 2-year moratorium, the 2-year "clean period" effectively resets for that particular condition. This means it remains excluded until you achieve a continuous 2-year symptom-free period.
Let's illustrate how moratorium underwriting plays out in practice:
| Scenario | Medical History (Past 5 years) | Moratorium Outcome (After Policy Start) |
|---|---|---|
| Scenario 1: Asthma | Diagnosed with mild asthma 3 years ago, using an inhaler occasionally. | Initial 2 years: Asthma-related treatment is excluded. If you need treatment for asthma within the first 2 years, it won't be covered. After 2 years: If you haven't used your inhaler, sought advice, or had any symptoms of asthma for a continuous 2-year period (starting from policy inception), then future asthma treatment may become covered. However, if you use your inhaler even once during that 2-year period, the 2-year clock resets. This makes it unlikely to be covered. |
| Scenario 2: Eczema | Had a flare-up of eczema 1 year ago, used a prescribed cream. | Initial 2 years: Eczema treatment is excluded. After 2 years: If you experience no symptoms or require no treatment for eczema for a continuous 2-year period from policy start, then future eczema treatment could be covered. If you have a flare-up and use cream, the 2-year clock resets. |
| Scenario 3: Migraines | Suffered from occasional migraines for 4 years, taking over-the-counter painkillers. | Initial 2 years: Migraine treatment is excluded. After 2 years: If you have gone a continuous 2-year period without any migraines, symptoms, or needing painkillers for them, then future migraine treatment might be covered. This is very difficult to achieve for recurring conditions. |
| Scenario 4: Knee Pain | Experienced knee pain 3 years ago, saw a physio, no issues since. | Initial 2 years: Any treatment for this specific knee pain is excluded. After 2 years: If you've had no symptoms, advice, or treatment for your knee for a continuous 2-year period since your policy started, then new knee issues could be covered. If the same knee pain returns after 2 years but you had symptoms during the moratorium, it remains excluded. |
Full Medical Underwriting (FMU) takes a different approach, prioritising clarity and certainty from day one. While it requires more effort upfront, it can offer greater peace of mind when it comes to making a claim.
With FMU, you are required to declare your entire medical history upfront during the application process. This typically involves completing a detailed medical questionnaire provided by the insurer. This questionnaire will ask about any conditions you've had, symptoms you've experienced, treatments you've received, and medications you've taken, usually going back 5 years or sometimes even longer for more serious conditions.
Based on the information you provide, the insurer will then:
Once this process is complete, you will receive your policy documents, which will clearly list any specific exclusions applied to your coverage. This means you know exactly what is and isn't covered from the moment your policy begins.
Let's consider how FMU handles the same scenarios:
| Scenario | Medical History (Past 5 years) | Full Medical Underwriting Outcome |
|---|---|---|
| Scenario 1: Asthma | Diagnosed with mild asthma 3 years ago, using an inhaler occasionally. | Outcome: The insurer will likely apply a permanent exclusion for asthma and any related respiratory conditions. You will know this exclusion is in place before the policy starts. Any future claims for asthma will be denied. |
| Scenario 2: Eczema | Had a flare-up of eczema 1 year ago, used a prescribed cream. | Outcome: Likely a permanent exclusion for eczema and skin-related conditions. You will be informed of this exclusion upfront. |
| Scenario 3: Migraines | Suffered from occasional migraines for 4 years, taking over-the-counter painkillers. | Outcome: Likely a permanent exclusion for migraines and any related neurological symptoms or conditions. You will know this at the outset. |
| Scenario 4: Knee Pain | Experienced knee pain 3 years ago, saw a physio, no issues since. | Outcome: If it was a one-off and you've had no issues since, the insurer might cover it, or they might apply a temporary exclusion for 1-2 years. Crucially, they will tell you their decision before the policy starts. If covered, future issues for the same knee could be included. |
To help you decide which underwriting type might be right for you, here's a direct comparison of Moratorium and Full Medical Underwriting:
| Feature | Moratorium Underwriting | Full Medical Underwriting (FMU) |
|---|---|---|
| Initial Declaration | Minimal; typically, you don't declare specific conditions unless asked during a claim. | Comprehensive; full medical history declared upfront via a detailed questionnaire. |
| Initial Setup Time | Quick and simple. | Slower; requires detailed information, potentially GP reports, and insurer assessment. |
| Certainty of Cover | Low. Uncertainty until a claim is made; relies on "clean period" for pre-existing conditions to become covered. | High. Clear exclusions are known and stated in your policy documents from day one. |
| Pre-existing Conditions | Automatically excluded for 2 years. May become covered after a continuous 2-year symptom-free period. | Assessed upfront. Specific exclusions applied, or in rare cases, a condition may be covered if deemed fully resolved and low risk. Permanent. |
| Claims Process | Can be more complex and slower, as medical history is reviewed at the point of claim to check for pre-existing issues. | Generally smoother and quicker, as pre-existing conditions have already been assessed and excluded (or covered). |
| Paperwork | Less at application, more potentially at claim. | More at application, less at claim. |
| Premium Cost | Often appears cheaper initially, but this can be misleading if a condition you thought would be covered is denied. | Might be higher if specific loadings are applied for a complex history, but offers known value. |
| Best Suited For | Generally healthy individuals with very few or no significant medical issues in recent history. | Individuals who want complete clarity on their cover from the outset, or those with a known, stable medical history they wish to declare. |
Choose Moratorium if:
Choose Full Medical Underwriting if:
While Moratorium and Full Medical Underwriting are the dominant types for individual and small group policies, it's worth briefly mentioning two others:
Continued Personal Medical Exclusions (CPME): This underwriting type is relevant when you are switching your private health insurance from one insurer to another. If you were previously on a Full Medical Underwritten policy with specific exclusions, CPME allows your new insurer to carry over those exact same exclusions. This means you don't have to go through the full medical underwriting process again, and your cover largely remains consistent with your previous policy's exclusions. It's a popular option for maintaining continuity of cover.
Medical History Disregarded (MHD): This is the "gold standard" of underwriting, but it is almost exclusively available for large corporate schemes (e.g., for companies with 250+ employees). Under MHD, employees are covered for all eligible conditions, regardless of their medical history, without individual underwriting. This means pre-existing conditions (that are acute, not chronic) are covered from day one. However, it's crucial to remember that chronic conditions (long-term, incurable) are still not covered under MHD. This option is extremely rare, if not impossible, for individual policies. Do not expect to find this for personal cover.
Regardless of the underwriting type you choose, here are some crucial tips for a smooth application and policy experience:
Choosing the right underwriting type and, indeed, the right private health insurance policy, is a significant decision.

While underwriting is foundational, several other factors significantly impact your private health insurance experience.
It bears repeating: Chronic conditions are not covered by standard UK private health insurance. This is a fundamental principle across all insurers and underwriting types.
PMI is for acute conditions – those that respond quickly to treatment and are likely to resolve fully. If an acute condition develops into a chronic one, the private cover typically ceases at that point, and ongoing management reverts to the NHS.
PMI primarily covers acute conditions. These are illnesses or injuries that:
Private medical insurance is not a substitute for the NHS; rather, it complements it. The NHS will always be there for emergencies, chronic condition management, and general healthcare. PMI offers an alternative for eligible acute treatments, typically providing:
It's easy to fall prey to common misunderstandings when dealing with private health insurance. Let's debunk a few:
"All pre-existing conditions are excluded forever, no matter what."
"My GP will automatically tell the insurer everything about me."
"My policy covers everything, including emergencies."
"Switching insurers means I lose all my previous cover and start from scratch."
"If my condition isn't serious, it won't be considered pre-existing."
The UK private health insurance market has seen significant shifts and growth in recent years, largely influenced by pressures on the NHS. Understanding these trends highlights why understanding underwriting is more critical than ever.
According to the Association of British Insurers (ABI), a leading voice for the UK insurance and long-term savings industry:
These statistics underscore a clear trend: more people are recognising the benefits of private health insurance in navigating the complexities of modern healthcare. However, with increased demand comes the imperative for consumers to be well-informed. The more people who rely on PMI, the more crucial it becomes to understand the nuances of underwriting, ensuring that their policy genuinely provides the anticipated peace of mind and access to care when it's needed most.
The clarity that robust underwriting provides is fundamental to this trust. As NHS waiting lists continue to be a concern, the ability to bypass these for acute, eligible conditions through private cover is a major driver. But this benefit is only fully realised when you understand the foundational rules of your policy, especially concerning pre-existing conditions and the chosen underwriting type.

Understanding the different underwriting types – particularly Moratorium and Full Medical Underwriting – is not merely an academic exercise; it's fundamental to getting the most out of your UK private health insurance. This knowledge is your shield against unexpected denials and ensures that your policy truly offers the peace of mind you seek.
While Moratorium underwriting offers a quicker setup and less initial hassle, its uncertainty at the point of claim can be a significant drawback for some. Full Medical Underwriting, though requiring more effort upfront, provides clarity and certainty from day one, allowing you to know exactly what's covered and what's excluded. Remember the golden rule: chronic conditions are not covered, and pre-existing conditions are a key focus of all underwriting.
Ultimately, the best underwriting type for you depends on your individual circumstances, medical history, and appetite for certainty versus initial convenience. Don't rush this decision. Take the time to understand your options, reflect on your medical past, and consider your future healthcare needs.
