In the intricate world of UK private health insurance (PMI), one of the most critical decisions you'll face isn't just about choosing your cover level or hospital list, but about the underwriting method your policy will employ. This fundamental choice—between Moratorium Underwriting and Full Medical Underwriting—can profoundly impact what you're covered for, the claims process, and even the cost of your premiums.
For many Britons, the National Health Service (NHS) remains the cornerstone of healthcare, and rightly so. It's a national treasure providing comprehensive care at the point of need. However, as the UK population ages and demand for services increases, the NHS faces unprecedented pressures, leading to longer waiting times for consultations, diagnostics, and elective surgeries. Recent data from NHS England shows that over 7.6 million people were waiting for hospital treatment in May 2024, with a significant proportion waiting over 18 weeks. This reality has led a growing number of individuals and families to consider private medical insurance, seeking quicker access to specialists, a choice of consultants, and often, more comfortable treatment environments.
The Association of British Insurers (ABI) reported that the number of people covered by PMI increased by 6.7% in 2022, reaching 7.2 million, the highest level in over a decade. This growth underscores the increasing reliance on private healthcare options. But before diving into policy specifics, understanding underwriting is paramount. It's how insurers assess your health risks and determine what conditions they will or won't cover. Getting this wrong can lead to unwelcome surprises at the point of claim.
This comprehensive guide will demystify Moratorium and Full Medical Underwriting, explore their advantages and disadvantages, and help you determine which method is best suited to your individual circumstances, ensuring you make an informed decision for your health and financial peace of mind.
At its core, underwriting in insurance is the process by which an insurer evaluates the risk of insuring a particular person or asset. For private medical insurance, this means assessing your health history to decide whether to offer you cover, at what price, and with what exclusions.
Why is this process so crucial? Insurers operate on the principle of pooled risk. Premiums from many policyholders contribute to a fund that pays out claims for the few who need it. If an insurer were to cover every pre-existing condition for everyone, the system would quickly become unsustainable. Underwriting allows insurers to:
The two primary methods of underwriting for individual private medical insurance in the UK are Moratorium Underwriting and Full Medical Underwriting. Each approaches this risk assessment in a distinct way, leading to different experiences for the policyholder.
Moratorium underwriting is often presented as the simpler and quicker option for obtaining private medical insurance. It's a "wait and see" approach, meaning the insurer doesn't ask for your full medical history upfront when you apply. Instead, they rely on a look-back period to determine coverage for pre-existing conditions.
Under a moratorium policy, the insurer will typically look back at your medical history for a specific period, usually 5 years prior to the start date of your policy. During this 5-year "look-back" period, any medical condition for which you have experienced symptoms, received treatment, sought advice, or taken medication will be considered a pre-existing condition.
The crucial element of moratorium underwriting is the "symptom-free" period. For any of these pre-existing conditions to potentially become covered in the future, you must go a continuous period of typically 2 years after the policy start date without experiencing any symptoms, requiring treatment, seeking advice, or taking medication for that specific condition. If you manage to complete this 2-year symptom-free period, that particular condition (and any related conditions) may then be covered by your policy.
However, if you experience symptoms or require treatment for a pre-existing condition within that 2-year symptom-free period, the clock for that condition effectively resets. The 2-year symptom-free period must be continuous. This can mean that some pre-existing conditions may never become covered if they are recurring or chronic.
Real-Life Example:
It is absolutely crucial to understand that even with a moratorium policy, standard private medical insurance in the UK does not cover chronic conditions, regardless of the underwriting method. The "symptom-free" period only allows for acute conditions that have ceased to be problematic to potentially become covered. We will delve into the critical distinction between acute and chronic conditions shortly.
Full Medical Underwriting (FMU) is the more traditional and thorough method of assessing your health history for private medical insurance. Unlike moratorium, FMU aims to establish a clear picture of your health before your policy even begins.
With FMU, when you apply for a policy, you will be required to complete a comprehensive medical questionnaire. This form asks detailed questions about your past and present health, including any conditions you've had, treatments you've received, medications you take, and any symptoms you've experienced.
Based on your answers, the insurer may do one or more of the following:
Real-Life Example:
Just like with moratorium, it's paramount to reiterate: standard UK private medical insurance, even with Full Medical Underwriting, does not cover chronic conditions. The exclusions applied are for pre-existing acute conditions, or conditions that might become chronic.
This is arguably the most misunderstood aspect of private medical insurance and a point of frequent contention for policyholders. It is absolutely crucial to grasp this fundamental principle:
Standard UK private medical insurance policies are designed to cover acute conditions that arise after your policy begins, or acute pre-existing conditions that become covered through moratorium's symptom-free period.
They are NOT designed to cover chronic conditions, regardless of when they developed.
In the context of PMI, a pre-existing condition is generally defined as any disease, illness, or injury for which you have experienced symptoms, received medical advice, diagnosis, or treatment, or taken prescribed medication, within a specified period (e.g., 5 years for moratorium) before the start date of your insurance policy.
An acute condition is a disease, illness, or injury that is likely to respond quickly to treatment and return you to your previous state of health. Examples include a broken bone, appendicitis, or a sudden infection. PMI aims to get you treated for these promptly.
A chronic condition is a disease, illness, or injury that has one or more of the following characteristics:
Examples of chronic conditions include diabetes, asthma, epilepsy, arthritis, Crohn's disease, long-term mental health conditions (like schizophrenia or bipolar disorder), and some forms of persistent back pain.
The exclusion of chronic conditions is a fundamental principle across virtually all standard UK private medical insurance policies. This isn't a loophole; it's a structural necessity for the insurance model to be sustainable. If insurers had to cover indefinite, ongoing treatments for lifelong conditions, the cost of premiums would be astronomically high, making policies unaffordable for the vast majority. The NHS, funded by general taxation, is the primary provider of care for chronic conditions in the UK.
Therefore, if you have a chronic condition, your private medical insurance will not cover the ongoing management, medication, or recurrent flare-ups of that condition, even if you were diagnosed after the policy started. It might cover an acute exacerbation if that specific exacerbation is treated quickly and returns you to your previous stable, chronic state, but the underlying chronic condition itself remains outside the scope of cover. Always clarify this with your insurer or broker if you have a specific chronic condition.
This distinction between acute and chronic, and the explicit exclusion of the latter, is a non-negotiable rule in UK private health insurance and must be understood clearly before purchasing a policy.
To help you visualise the differences, here's a direct comparison of Moratorium and Full Medical Underwriting:
| Feature | Moratorium Underwriting | Full Medical Underwriting (FMU) |
|---|---|---|
| Application Process | Quick and simple. No detailed medical questions upfront. | Longer and more detailed. Requires a full medical questionnaire. GP reports may be requested. |
| Initial Disclosure | Minimal upfront disclosure. | Full disclosure of medical history required. |
| Exclusions | Automatic exclusions for conditions treated/symptomatic in the last 5 years. Assessed at claim. | Specific, named exclusions applied at policy inception based on declared history. |
| Certainty of Cover | Less certain. You only know if a pre-existing condition is covered when you claim. | High certainty. You know exactly what is and isn't covered from day one. |
| Pre-existing Conditions | May become covered after 2 continuous symptom-free years post-policy start. | Permanently excluded if identified and named at application. |
| Chronic Conditions | Not covered. | Not covered. |
| Claims Process | Insurer investigates medical history at claim stage for any pre-existing conditions. | Claims are usually smoother for new conditions as pre-existing status is already assessed. |
| Suitability | Ideal for individuals with a very clean recent medical history, or those seeking quick cover. | Ideal for individuals with a complex medical history who want certainty, or those who value transparency. |
| Cost Implications | Often slightly higher initial premiums to account for unknown risks. | Can lead to higher premiums (loadings) for specific risks, or lower for very healthy individuals. |
This table highlights that while moratorium offers speed and simplicity upfront, it trades that for uncertainty at the point of claim. FMU demands more effort initially but provides clear peace of mind regarding what your policy will cover.
Deciding between moratorium and full medical underwriting is a personal choice, with no single "best" option. Your ideal choice will depend on your individual circumstances, medical history, risk tolerance, and priorities.
Consider the following factors:
| Your Situation | Best Suited Underwriting Method | Rationale |
|---|---|---|
| Very Healthy, no issues in last 5+ years | Moratorium or Full Medical Underwriting | Moratorium is quicker; FMU offers guaranteed clarity. Both likely lead to full cover. |
| Had an acute illness/injury 3 years ago, now fully resolved | Moratorium (if 2-year rule met) or FMU | Moratorium offers potential for cover after 2 symptom-free years; FMU will assess and may not exclude. |
| Recurring back pain in last 5 years | Full Medical Underwriting | Moratorium unlikely to ever cover it (chronic/recurring). FMU will likely exclude it, giving you certainty. |
| Diagnosed with diabetes 1 year ago | Neither (for the chronic condition) | Standard PMI doesn't cover chronic conditions. FMU will explicitly exclude. Moratorium will also exclude due to recency. |
| Want absolute clarity on exclusions upfront | Full Medical Underwriting | Avoids surprises at claim stage. |
| Need cover very quickly | Moratorium | Minimal paperwork, faster activation. |
| Concerned about privacy of medical history | Moratorium | Less invasive at application, but medical history is reviewed at claim. FMU reviews upfront. |
| Employer offers PMI via a Group Scheme | Medical History Disregarded (MHD) | Often available in group policies, offering cover regardless of history (excluding chronic conditions). This is a distinct type of underwriting often not available for individual policies. |
Ultimately, the goal is to secure a policy that genuinely meets your needs and provides the peace of mind you seek. Rushing into a decision without fully understanding the implications of your chosen underwriting method can be a costly mistake.
Regardless of the underwriting method, the application process for private medical insurance generally follows these steps:
Honesty is the Best Policy: It cannot be stressed enough how vital it is to be completely honest and transparent during the application process, especially with Full Medical Underwriting. Failure to disclose relevant medical information, even if unintentional, can lead to your policy being declared void, and any claims being denied. Insurers have the right to investigate your medical history at the point of claim, and discrepancies will come to light.
It's worth a brief mention that if you're fortunate enough to have private medical insurance offered through your employer as part of a group scheme, the underwriting method might be different and often more favourable, particularly for those with pre-existing conditions.
Many group schemes offer Medical History Disregarded (MHD) underwriting. Under MHD, the insurer largely disregards your medical history, meaning pre-existing conditions (excluding chronic conditions, which are still typically not covered) are covered from day one. This is because the risk is spread across a large group of employees, making it actuarially viable for the insurer.
If MHD is available, it is often the most advantageous form of underwriting, especially if you have a medical history that would otherwise lead to exclusions under individual moratorium or FMU policies. However, MHD is usually only available for corporate policies and is not typically an option for individual policies purchased directly.
