TL;DR
For UK private medical insurance, The Exeter generally offers more underwriting flexibility for pre-existing conditions than Aviva. As experienced brokers who have arranged over 900,000 policies, WeCovr can navigate their specific approaches to secure the best possible terms for your medical history.
Key takeaways
- The Exeter, a friendly society, is renowned for its flexible 'Full Medical Underwriting' for complex health histories.
- Aviva's 'Healthier Solutions' is a leading policy, but is often stricter with pre-existing conditions on new individual plans.
- Standard UK PMI does not cover chronic conditions; it is designed for new, acute medical issues that arise after your policy starts.
- 'Moratorium' underwriting is the most common type, automatically excluding recent conditions for a set period.
- Using a specialist broker like WeCovr is vital to match your medical history to the insurer most likely to offer favourable terms.
Navigating the world of UK private medical insurance (PMI) can be a daunting task, especially if you have a pre-existing medical condition. At WeCovr, where our experienced team has helped arrange over 900,000 policies of various kinds, a common question we encounter is how different insurers view complex medical histories. Two of the market's leading names, Aviva and The Exeter, have distinctly different approaches, making the choice between them critical.
This comprehensive guide compares Aviva and The Exeter, offering a deep dive into their underwriting philosophies to help you understand which might be the better fit for your personal circumstances.
A deep dive into underwriting flexibility for complex medical histories
Before we compare the two insurers, it’s crucial to understand the engine room of any insurance policy: underwriting.
Underwriting is simply the process an insurer uses to assess your health and medical history to decide if they can offer you cover and on what terms. For PMI, this process is laser-focused on pre-existing conditions.
There are two main types of underwriting for personal health insurance policies in the UK:
- Moratorium (Mori) Underwriting: This is the most common and straightforward method. The insurer doesn't ask for your full medical history upfront. Instead, they apply a general rule: any condition for which you've had symptoms, treatment, or advice in the 5 years before your policy start date is automatically excluded for an initial period (usually the first 2 years of the policy).
- Full Medical Underwriting (FMU): With FMU, you complete a detailed health questionnaire as part of your application. The insurer's underwriters review your entire medical history. Based on this, they will offer you a policy with specific, named exclusions for certain conditions. In some cases, they might charge a higher premium (a "loading") to cover a condition, or decline to offer cover altogether.
While FMU sounds more intensive, for those with known medical issues, it provides absolute clarity from day one about what is and isn't covered.
Insider Tip: A common mistake is assuming that after the 2-year moratorium period, all previous conditions are automatically covered. This is only true if you have remained completely free of symptoms, treatment, medication, or advice for that condition for a continuous 2-year period after your policy began.
Understanding Pre-Existing and Chronic Conditions in UK PMI
It is a fundamental principle of the UK private health insurance market that policies are designed to cover new, acute conditions that arise after your policy begins.
Let's be perfectly clear on the terminology insurers use:
- Pre-existing Condition: Any disease, illness, or injury for which you have experienced symptoms, received medication, advice, or treatment in a set period (usually 5 years) before the start of your cover.
- Chronic Condition: A condition that is long-lasting, has no known cure, and requires ongoing or long-term monitoring and management. Examples include diabetes, asthma, high blood pressure, and Crohn's disease.
Standard private medical insurance in the UK does not cover the routine management of chronic conditions. However, some policies may cover acute flare-ups of a chronic condition, provided it wasn't a pre-existing condition at the time you joined. This is a complex area where an expert broker's advice is invaluable.
Aviva Health Insurance: The 'Healthier Solutions' Approach
Aviva is one of the largest and most recognised insurers in the UK, and their flagship PMI product, 'Healthier Solutions', is a comprehensive and popular choice.
Aviva's Underwriting Stance: For new individual policies, Aviva predominantly uses moratorium underwriting. This "wait-and-see" approach is efficient and works well for individuals with a clean or straightforward medical history.
- The '2-5-2' Rule: Aviva applies the standard 5-year lookback for pre-existing conditions. Any such condition is excluded for the first 2 years of your policy. If you then go for a continuous 2-year period without any symptoms, treatment, or advice for that condition, it may become eligible for cover.
- Full Medical Underwriting (FMU): Aviva does offer FMU, but it's less common on their individual plans compared to moratorium. Their underwriting can be relatively strict. If you declare a significant medical history, it's more likely they will apply a broad exclusion relating to that condition (e.g., "all conditions relating to the digestive system") or may decline the application.
- Group Schemes: It's worth noting that Aviva is a major provider of corporate health insurance. On larger company schemes, underwriting terms are often more generous, and pre-existing conditions can sometimes be covered through specific arrangements like 'Medical History Disregarded' (MHD) underwriting.
In essence, Aviva's 'Healthier Solutions' is an excellent, top-tier product, but for an individual with a complex medical history, securing favourable terms on a new policy can be challenging.
Real-Life Example: John's Knee Injury
John had keyhole surgery on his knee 3 years before applying for an Aviva policy on a moratorium basis. For the first 2 years of his policy, anything related to that knee would be excluded. If, after 2 years, he has had no further pain, physiotherapy, or consultations for his knee, a new problem with it (e.g., a different type of ligament tear) could potentially be covered.
The Exeter Health Insurance: A Specialist's Perspective
The Exeter is a Friendly Society, which means it is owned by its members rather than shareholders. This mutual status often informs a more member-centric and flexible approach, particularly when it comes to underwriting.
The Exeter's Underwriting Stance: The Exeter has built a strong reputation among brokers for its willingness to consider applicants that other insurers might immediately decline. They specialise in Full Medical Underwriting.
- Focus on FMU: While they do offer moratorium, The Exeter's strength lies in its expert FMU process. They encourage applicants with medical histories to apply on an FMU basis, allowing their underwriters to conduct a detailed, personal assessment.
- Granular Exclusions: Instead of applying a broad exclusion, The Exeter's underwriters are more likely to apply a very specific one. For example, instead of excluding "all cardiac conditions," they might specifically exclude "arrhythmia" if that is the specific issue, while still offering cover for other potential heart problems.
- Premium Loadings: In some cases, where other insurers would decline, The Exeter might offer cover for a condition in return for a higher premium (a "loading"). This gives the applicant the choice and control.
- Mental Health: This is a key area of difference. Many insurers apply blanket exclusions for mental health if you have any history of anxiety or depression. The Exeter is known for taking a more nuanced view, often assessing the severity and timescale of the condition to offer more tailored cover.
In essence, The Exeter's 'Health+' policy is designed for those who value clarity and may have been turned away elsewhere. Their flexibility makes them a go-to choice for brokers dealing with clients who have complex medical needs.
Real-Life Example: Sarah's Mild Anxiety
Sarah has a history of mild anxiety, managed with a low-dose antidepressant for the last few years. On an FMU application with The Exeter, the underwriters would likely review a report from her GP. Instead of a blanket mental health exclusion, they might offer full cover with a specific exclusion for "anxiety and depression," meaning other psychiatric conditions could still be covered. This is a level of detail many larger insurers may not offer.
Head-to-Head Comparison: Aviva vs The Exeter for Pre-Existing Conditions
This table summarises the key differences in their approach to underwriting complex medical histories.
| Feature | Aviva ('Healthier Solutions') | The Exeter ('Health+') | WeCovr Adviser Insight |
|---|---|---|---|
| Primary Underwriting | Moratorium | Full Medical Underwriting (FMU) | The Exeter's FMU provides upfront certainty, which is invaluable for anyone with a known health condition. |
| Flexibility on Pre-Existing Conditions | Lower. Tends to be stricter, often leading to broad exclusions or declines for complex cases. | Higher. Renowned for its expert underwriters who assess each case individually. | We often approach The Exeter for clients who have been declined or offered poor terms by other mainstream insurers. |
| Approach to Mental Health | Generally strict. A history of mental health issues often leads to a broad exclusion on new policies. | More flexible and nuanced. They will review the specifics and may offer cover with tailored exclusions. | This is The Exeter's standout feature. They are one of the most progressive insurers for mental health history. |
| Chronic Condition Stance | Standard exclusion for all chronic conditions. | Standard exclusion for all chronic conditions. | No UK PMI policy is designed to cover chronic conditions. This is a universal rule. |
| Application Process (FMU) | Can be lengthy; may result in a simple decline without detailed feedback. | Detailed but transparent. They are more likely to engage in a dialogue to find a solution (e.g., exclusion vs. loading). | A broker can manage the FMU process, ensuring the underwriter gets the right information to make a fair decision. |
| Best For... | Individuals with a clean medical history; those on a corporate scheme; brand-led buyers. | Individuals with any pre-existing conditions; those who value certainty; people who have been declined elsewhere. | The "best" choice is entirely personal. We analyse your specific history to recommend the right path. |
| Value-Added Services | Aviva Digital GP, Mental Health support pathways (subject to underwriting). | HealthWise App: Remote GPs, physiotherapy, and mental health support, accessible to all members regardless of underwriting. | The Exeter's HealthWise is a superb benefit as it's available even for conditions excluded from the main policy. |
The Role of a Specialist PMI Broker in Navigating Complex Histories
For anyone with a health condition, going directly to an insurer is a high-risk strategy. You only get one chance to make a first impression with an underwriter, and a poorly completed application can lead to an automatic decline that stays on your record.

Switching Your PMI Policy with Pre-Existing Conditions
If you already have a PMI policy and want to switch, perhaps due to a high renewal premium, the process is even more sensitive. If you've developed conditions while covered by your old policy, you need to protect that cover.
The best way to do this is with Continued Personal Medical Exclusions (CPME) underwriting. This allows you to transfer your existing underwriting terms to a new insurer, ensuring conditions that were previously covered remain so.
Both Aviva and The Exeter offer CPME switching terms, but their willingness to accept you will depend on your claims history. This is another area where a broker can manage the process to ensure a seamless transition without any loss of cover.
Final Verdict: Aviva or The Exeter?
So, which is better for pre-existing conditions?
-
The Exeter is the clear winner for individuals with complex or even minor pre-existing medical conditions who are seeking a new personal policy. Their specialist FMU approach provides a level of flexibility and transparency that is hard to beat. They are built to handle non-standard cases.
-
Aviva remains a formidable choice for those with a clean bill of health or for those joining a company health scheme, where underwriting rules are often more lenient. Their 'Healthier Solutions' policy is one of the most comprehensive on the market.
Ultimately, the right choice is not about the brand, but about the specific terms their underwriters are prepared to offer you. The only way to know for sure is to have your case professionally assessed.
