Choosing a private medical insurance policy in the UK can feel complex, but it doesn't have to be. As an FCA-authorised broker that has helped arrange over 900,000 policies, WeCovr is here to demystify the process. A key decision you'll face is the type of underwriting: Moratorium or Full Medical Underwriting.
This choice determines how an insurer assesses your medical history and what they will cover. Understanding the difference is crucial to finding a policy that offers you security and peace of mind. In this guide, we'll break down everything you need to know to make the right choice for you and your family.
Before we dive into the two main types, let's clarify what "underwriting" means.
In simple terms, underwriting is the process an insurance company uses to understand the level of risk you present. For health insurance, this means looking at your medical history to decide the terms of your policy. The primary goal is to identify any pre-existing medical conditions.
This brings us to the most critical point about private medical insurance (PMI) in the UK:
Standard PMI policies are designed to cover new, unforeseen, and acute medical conditions that arise after your policy begins. They are generally not designed to cover pre-existing conditions or chronic conditions.
It's vital to understand the difference between 'acute' and 'chronic' conditions:
The type of underwriting you choose—Moratorium or Full Medical Underwriting—is simply the method the insurer uses to identify and handle these pre-existing conditions.
Moratorium underwriting is the most common type offered in the UK. It's often favoured for its speed and simplicity.
With a moratorium policy, you don't have to complete a lengthy medical questionnaire when you apply. Instead, the insurer applies a blanket temporary exclusion for any medical conditions for which you have experienced symptoms, received medication, or sought advice or treatment in the five years leading up to your policy start date.
How does it work?
The key feature is the "moratorium period," which is typically two years from the date your policy starts.
A Real-Life Example:
Let's say David had physiotherapy for shoulder pain 18 months before he took out a moratorium policy. For the first two years of his policy, any claims related to his shoulder would be excluded.
- Scenario A: David goes for two full years without any shoulder pain, medication, or consultations. After this point, if he develops a new problem with his shoulder, it would likely be covered.
- Scenario B: One year into his policy, David's shoulder pain returns, and he sees his GP. This visit "resets the clock." His shoulder will remain an exclusion, and he would need to go another two continuous years from this GP visit without any shoulder issues for it to be considered for cover again.
| Pros of Moratorium | Cons of Moratorium |
|---|---|
| Quick & Simple Application: You can get cover in place very quickly without filling out long medical forms. | Lack of Upfront Certainty: You only discover if a condition is covered when you make a claim. |
| Less Intrusive: You don't need to recall and disclose your entire medical history from the outset. | Slower Claims Process: The insurer will need to investigate your medical history at the point of a claim, which can cause delays. |
| Potential for Cover: Pre-existing conditions have a pathway to becoming covered over time, which isn't usually possible with FMU. | The "Rolling" Nature: The two-year clock can reset, making it hard to predict when, or if, a condition will ever be covered. |
| Often Good Value: Because the admin is lower upfront, moratorium policies can sometimes be slightly more affordable. | Potential for Disputes: The ambiguity can sometimes lead to disagreements about whether a new symptom is related to a past condition. |
Moratorium underwriting is an excellent choice for:
Full Medical Underwriting (FMU) is the more traditional method. As the name suggests, it involves a full declaration of your medical history at the time of application.
With FMU, you will be asked to complete a detailed health questionnaire. You must disclose information about past consultations, treatments, and conditions for yourself and any other family members on the policy.
The insurer's underwriting team will then review your answers and decide on the terms of your policy.
How does it work?
Unlike a moratorium, these exclusions are typically permanent. However, some insurers may be willing to review an exclusion after a certain number of years if you can provide medical evidence that the condition is fully resolved.
A Real-Life Example:
Let's say Sophia applies for a policy with FMU. On her form, she declares that she had surgery for an ovarian cyst three years ago. The insurer reviews this and adds a permanent exclusion to her policy for "any investigation or treatment related to ovarian cysts." A year later, she develops knee pain and needs an MRI scan. Because this is unrelated to her exclusion, her claim is processed quickly and without any queries about her past gynaecological history. She had total clarity from day one.
| Pros of FMU | Cons of FMU |
|---|---|
| Total Certainty: You know exactly what is and isn't covered from the moment your policy starts. No surprises at the point of a claim. | Longer Application Process: Completing the medical questionnaire can be time-consuming and requires you to recall past medical details accurately. |
| Faster Claims: As the underwriting is done upfront, claims are generally much quicker and more straightforward to process. | Can Feel Intrusive: Some people are uncomfortable disclosing their entire medical history. |
| Clear & Transparent: All exclusions are explicitly named in your policy documents, leaving no room for ambiguity. | Permanent Exclusions: Declared conditions are usually excluded for the life of the policy, with no pathway to being covered later. |
| Potential for Review: In some cases, you may be able to ask the insurer to review an exclusion after several years of being symptom-free. | Forgetting is a Risk: If you accidentally forget to declare a condition, an insurer could decline a future claim and even void your policy. |
Full Medical Underwriting is often the better choice for:
To help you decide, here is a direct comparison of the key features of each underwriting type.
| Feature | Moratorium Underwriting | Full Medical Underwriting (FMU) |
|---|---|---|
| Application Process | Quick & simple. No upfront medical questionnaire. | Longer & more detailed. Requires a full declaration of your medical history. |
| Cover for Pre-existing Conditions | Conditions from the last 5 years are excluded. They may become covered after a continuous 2-year trouble-free period on the policy. | Conditions you declare are assessed and typically excluded from the start. These exclusions are usually permanent. |
| Certainty of Cover | Low. You only find out if a condition is covered when you submit a claim. This can lead to uncertainty when you need care. | High. Your policy documents clearly list all exclusions from day one. You have complete transparency. |
| Claims Process | Can be slower. The insurer needs to investigate your medical history at the time of the claim to check if it's a new or pre-existing condition. | Generally faster and smoother. The underwriting work is already done, so unrelated claims are processed with minimal fuss. |
| Best For | Healthy individuals wanting a fast start; those with very minor past issues who are happy with the "wait and see" approach. | People with a known or complex medical history who want absolute clarity on their cover before they commit. |
| Cost | Can sometimes be slightly cheaper due to lower initial administration. | The price is based on the risk assessed from your application. It can be more or less expensive depending on your health. |
The right choice is personal. It depends on your health, your attitude to risk, and what you value most in an insurance policy. Let's look at some common scenarios.
Scenario 1: Aisha, 28, Fit and Healthy Aisha has rarely visited her GP and has no ongoing health concerns. For her, a Moratorium policy is likely ideal. It's fast to set up, and since she has no pre-existing conditions to worry about, the lack of upfront certainty is not a major drawback.
Scenario 2: Ben, 42, Past Knee Injury Ben had physiotherapy for a recurring knee ligament sprain two years ago. He wants to ensure that if he needs surgery in the future, he'll be covered.
Scenario 3: Carol, 55, Prefers Certainty Carol is in good health but had a benign lump removed from her back four years ago. She doesn't want any hassle or delays if she ever needs to claim.

With NHS waiting lists remaining a significant concern, more people than ever are turning to private health cover for prompt access to treatment. According to the latest NHS England data, the referral to treatment (RTT) waiting list involves several million treatment pathways. In late 2024, this figure stood at around 7.56 million. Private medical insurance offers a valuable way to bypass these queues for eligible acute conditions.
It's important to remember that PMI complements the NHS rather than replacing it. The NHS remains world-class for:
PMI gives you choice and control over your elective (planned) healthcare, allowing you to be seen and treated quickly at a time and hospital that suits you.
