TL;DR
As an FCA-authorised expert with over 900,000 policies arranged, WeCovr helps demystify the choices you face when buying private medical insurance in the UK. One of the biggest decisions is selecting the right type of underwriting. This guide breaks down everything you need to know about Full Medical Underwriting and Moratorium underwriting.
Key takeaways
- Health Questionnaire: You will fill out a detailed application form. This will ask questions about your health, lifestyle, and medical history. You'll need to disclose any conditions, treatments, consultations, or symptoms you've experienced, typically within the last five years, but sometimes longer.
- Information Gathering: You must be honest and thorough. Insurers may ask for your permission to contact your GP to verify information or get more details about a condition you've declared.
- The Underwriting Decision: The insurer's underwriting team will review your application. They will then issue your policy documents, which will clearly state any personal medical exclusions. These are specific conditions or body parts that will not be covered by your policy.
- The Moratorium Period: You must have the policy for a continuous period, usually two years.
- The Symptom-Free Period: During that two-year period, you must not have any symptoms, treatment, medication, or advice for that specific pre-existing condition.

Understanding Underwriting Full vs Moratorium
Choosing your private medical insurance (PMI) is a significant step towards taking control of your health. But before you can access fast-track consultations and private hospital rooms, you'll encounter a crucial term: underwriting.
Underwriting is simply the process an insurer uses to assess your health and medical history. This helps them decide what they can and can't cover on your policy and at what price. The two main ways they do this in the UK are Full Medical Underwriting (FMU) and Moratorium (MORI) Underwriting.
The choice you make has a major impact on what your policy covers, how quickly it's set up, and what happens when you need to make a claim. Let's break down the differences to help you decide which path is right for you.
The Golden Rule of UK Private Health Insurance
Before we dive into the details, it's vital to understand a fundamental principle of standard UK private medical insurance:
PMI is designed to cover new, acute conditions that arise after your policy begins.
An acute condition is a disease, illness, or injury that is likely to respond quickly to treatment and lead to a full recovery (like a cataract or a hernia). PMI does not cover chronic conditions – long-term illnesses that have no known cure and need ongoing management, such as diabetes, asthma, or high blood pressure. It also does not cover pre-existing conditions unless they are specifically accepted by the insurer, which is rare. Understanding this distinction is key to having the right expectations for your health cover.
Full Medical Underwriting (FMU): The Path of Certainty
Full Medical Underwriting is exactly what it sounds like: a complete, upfront review of your medical history. It’s the more traditional approach, favouring total transparency from the outset.
How Does Full Medical Underwriting Work?
The process is straightforward but requires some effort on your part:
- Health Questionnaire: You will fill out a detailed application form. This will ask questions about your health, lifestyle, and medical history. You'll need to disclose any conditions, treatments, consultations, or symptoms you've experienced, typically within the last five years, but sometimes longer.
- Information Gathering: You must be honest and thorough. Insurers may ask for your permission to contact your GP to verify information or get more details about a condition you've declared.
- The Underwriting Decision: The insurer's underwriting team will review your application. They will then issue your policy documents, which will clearly state any personal medical exclusions. These are specific conditions or body parts that will not be covered by your policy.
Example: Sarah, a 48-year-old marketing director, had physiotherapy for knee pain three years ago. On her FMU application, she declares this. The insurer might review her GP records and decide to place an exclusion on her policy for any future knee-related problems. From day one, Sarah knows exactly where she stands: her policy will cover a new hip problem, but not a flare-up of her old knee trouble.
The Pros and Cons of Full Medical Underwriting
| Feature | Pros (The Good Bits) | Cons (The Downsides) |
|---|---|---|
| Clarity | ✅ Crystal Clear Cover: You know precisely what is and isn't covered from the very beginning. No nasty surprises when you claim. | ❌ Potential for Exclusions: Conditions you might have considered minor could be permanently excluded. |
| Process | ✅ Smoother Claims: As the insurer already has your medical history, claims are often processed faster without the need for deep investigation. | ❌ Upfront Admin: It takes time and effort to complete the detailed forms accurately. |
| Setup Time | ✅ Thorough Review: The insurer has a complete picture, leading to a tailored policy. | ❌ Slower Start: The policy can take longer to issue while the insurer reviews your details and potentially contacts your GP. |
| Privacy | ✅ One-Time Disclosure: You deal with the medical questions once at the start. | ❌ Intrusive Questions: You have to share personal and sometimes sensitive medical information. |
Who Should Consider Full Medical Underwriting?
FMU is often the best choice for individuals who:
- Value certainty and want to eliminate any ambiguity about their cover.
- Have had previous medical issues and want to know for sure if they will be covered.
- Are happy to do the paperwork upfront for a smoother process later.
- Want the peace of mind that comes from a clear, contractually-defined policy.
Moratorium Underwriting (MORI): The "Wait and See" Approach
Moratorium underwriting is the most common type for individual PMI policies in the UK. It’s a faster, less invasive way to get cover, but it comes with a trade-off: a lack of initial certainty.
How Does Moratorium Underwriting Work?
With a moratorium policy, you don't complete a detailed health questionnaire. Instead, the policy automatically excludes any medical conditions for which you have had symptoms, treatment, medication, or advice in the five years before the policy start date.
Here's the key part: these conditions can become eligible for cover later on, subject to two main rules:
- The Moratorium Period: You must have the policy for a continuous period, usually two years.
- The Symptom-Free Period: During that two-year period, you must not have any symptoms, treatment, medication, or advice for that specific pre-existing condition.
If you meet both these criteria, the condition may no longer be considered pre-existing and could be covered in the future. This is often referred to as a "rolling" moratorium because the two-year clock can restart if you have a flare-up or seek advice for the condition.
Example: David, a 32-year-old software developer, takes out a moratorium policy. Four years ago, he saw his GP for occasional migraines. For the first two years of his policy, any claims related to headaches or migraines would be automatically rejected. However, if David goes for two full years on the policy without seeking any treatment, medication, or advice for his migraines, they could then become eligible for cover in his third year.
The Pros and Cons of Moratorium Underwriting
| Feature | Pros (The Good Bits) | Cons (The Downsides) |
|---|---|---|
| Clarity | ✅ Potential for Future Cover: Old conditions can become covered over time if you stay well. | ❌ Uncertainty at Claim Time: You don't know for sure if a condition is covered until you make a claim and the insurer investigates your history. |
| Process | ✅ Quick and Easy Setup: You can get covered in minutes with no lengthy forms. | ❌ Claims Can Be Delayed: The underwriting happens at the point of claim, which can be a stressful and slow process. |
| Setup Time | ✅ Immediate Cover: Your policy can be up and running very quickly. | ❌ The "Rolling" Clause: The 2-year symptom-free clock can be reset by a minor consultation, pushing back potential cover. |
| Privacy | ✅ Less Intrusive: You don't have to disclose your full medical history at the start. | ❌ History is Investigated Later: The insurer will ask for access to your medical records when you claim. |
Who Should Consider Moratorium Underwriting?
MORI is often a great fit for people who:
- Are generally in good health with no significant medical history in the last five years.
- Want to get a policy set up as quickly as possible.
- Prefer not to go through the process of digging up their full medical history.
- Are younger and less likely to have a complex medical background.
At a Glance: Full Medical Underwriting vs. Moratorium
| Aspect | Full Medical Underwriting (FMU) | Moratorium Underwriting (MORI) |
|---|---|---|
| Application Process | Detailed health questionnaire required. | No medical questionnaire at the start. |
| Speed of Setup | Slower (days or weeks). | Fast (minutes or hours). |
| Clarity of Cover | High – you know exactly what’s excluded from day one. | Low – cover is determined at the point of claim. |
| Claim Process | Generally faster, as underwriting is already done. | Slower, as insurer investigates your history when you claim. |
| Privacy | Intrusive at the start, less so at claim time. | Less intrusive at the start, more so at claim time. |
| Pre-existing Conditions | Explicitly excluded in writing from the start. | Automatically excluded for a set period, but can become eligible for cover later if you remain symptom-free. |
| Best For | People who want certainty and don't mind upfront admin. | Healthy people who want a quick setup and are comfortable with some ambiguity. |
Expert Guidance from WeCovr

Beyond Underwriting: Other Factors That Shape Your Policy
While underwriting is a cornerstone of your policy, other choices will also define your cover and premium:
- Hospital List: Insurers offer tiered lists of private hospitals. A policy covering only local hospitals will be cheaper than one that includes premium central London facilities.
- Excess (illustrative): This is the amount you agree to pay towards a claim each year. A higher excess (£500 or £1,000) will lower your monthly premium, while a lower excess (£0 or £100) will increase it.
- Outpatient Cover (illustrative): This covers consultations and diagnostics that don't require a hospital bed. You can choose from full cover, a limited amount (e.g., £1,000 per year), or no outpatient cover to reduce costs.
- Therapies Cover: This includes treatments like physiotherapy, osteopathy, and chiropractic care, which are often a key reason for claiming.
- Mental Health Cover: Support for mental health is an increasingly important part of modern PMI. Cover levels vary significantly between insurers.
Small Lifestyle Changes, Big Health Impact
Private medical insurance is there for when things go wrong, but living a healthy lifestyle can reduce your chances of needing it. Small, consistent habits can have a profound impact on your long-term well-being.
- Nourish Your Body: Aim for a balanced diet rich in fruits, vegetables, and whole grains. According to the NHS, eating at least five portions of a variety of fruit and veg a day can lower your risk of serious health problems. Tracking your intake can be a powerful tool. That's why WeCovr provides complimentary access to our AI-powered calorie and nutrition tracking app, CalorieHero, to all our PMI and life insurance clients.
- Prioritise Sleep: Most adults need 7-9 hours of quality sleep per night. Poor sleep is linked to a higher risk of conditions like heart disease and diabetes. Create a relaxing bedtime routine and make your bedroom a screen-free zone.
- Move Every Day: The UK Chief Medical Officers' guidelines recommend at least 150 minutes of moderate-intensity activity a week. This could be a brisk walk, a cycle ride, or a dance class. Find something you enjoy to make it a sustainable habit.
- Manage Stress: Chronic stress can impact your physical health. Practices like mindfulness, spending time in nature, or simply talking to a friend can make a real difference.
When you purchase a policy through WeCovr, you not only gain peace of mind but also discounts on other insurance products, helping you protect your family and your finances in a holistic way.
The UK Health Landscape: Why People Choose PMI
The NHS is a national treasure, but it is facing unprecedented pressure. According to the latest NHS England data, the waiting list for consultant-led elective care stands at over 7.5 million. For many, this uncertainty is the primary driver for considering private medical insurance.
The Association of British Insurers (ABI) notes that around 1.7 million people in the UK have a private medical insurance policy, with insurers paying out over £7.6 million every day for treatments. This investment allows people to bypass long waits for diagnosis and treatment, giving them control, choice, and a quicker return to their normal lives.
