Understanding the Core of UK Private Medical Insurance (PMI)
Before we dive deeper, it's essential to understand what private medical insurance is—and what it isn't.
UK PMI is designed to cover the diagnosis and treatment of acute conditions. An acute condition is a disease, illness, or injury that is likely to respond quickly to treatment and lead to a full recovery. Think of things like joint replacements, cataract surgery, or hernia repairs.
Crucially, standard UK private health cover does not cover:
- Pre-existing conditions: Any illness or injury you had before your policy started.
- Chronic conditions: Conditions that require long-term management rather than a cure, such as diabetes, asthma, or high blood pressure. These remain under the care of the NHS.
Other standard exclusions include routine pregnancy, cosmetic surgery, and emergency services (A&E is an NHS service).
Key Terms Explained in Plain English
- Underwriting: This is how an insurer assesses your medical history to decide what they will cover. The two main types are:
- Moratorium (Most Common): You don't declare your full medical history upfront. The insurer automatically excludes any condition you've had symptoms, advice, or treatment for in the 5 years before joining. However, if you remain symptom-free for a continuous 2-year period after your policy starts, that condition may become eligible for cover.
- Full Medical Underwriting (FMU): You complete a detailed health questionnaire. The insurer reviews it and lists specific, permanent exclusions on your policy from day one. This provides certainty but is more admin-heavy.
- Excess (illustrative): The amount you agree to pay towards a claim each policy year. A higher excess (e.g., £500) will result in a lower monthly premium than a lower excess (e.g., £100).
- No Claims Discount (NCD): A discount applied to your premium for every year you don't make a claim, similar to car insurance. Making a claim will typically reduce your NCD level at renewal.
Deep Dive: Hospital Lists and Networks
Where you can be treated is one of the most significant factors in any PMI policy. Both Bupa and Aviva use tiered hospital lists to manage costs and provide choice.
Why does the hospital list matter? Choosing a more restricted list excludes premium-priced city-centre hospitals (especially in London), significantly lowering your monthly premium. However, it also means you may have to travel further for treatment.
Bupa's Hospital Network
Bupa's network is known for its breadth and clarity. They typically offer three main tiers:
- Essential Access: A curated list of private and NHS hospitals across the UK, excluding the most expensive facilities. Ideal for keeping costs down if you don't live near a major city centre.
- Extended Choice: This is their core list, providing access to a wide range of private hospitals nationwide.
- Extended Choice with Central London: The most comprehensive and expensive option. It includes the Extended Choice list plus the high-end private hospitals in central London (e.g., The Lister, The London Clinic).
Insider Tip: Bupa also owns and operates its own facilities, including the flagship Bupa Cromwell Hospital in London. Being a Bupa member can sometimes offer streamlined access within their own network.
Aviva's Hospital Network
Aviva also uses a tiered system, but with a unique twist in its 'Expert Select' option.
- Key: Aviva's budget-friendly list, which uses a select network of private hospitals and some NHS facilities.
- Extended: A broader list of hospitals, similar in scope to Bupa's Extended Choice.
- Expert Select (Hospital Option): This is Aviva's "guided" option. When you need treatment, Aviva gives you a shortlist of up to 5 consultant and hospital options from their Extended list. By agreeing to this guided choice, you can achieve significant premium savings. You still get high-quality care, but you don't have complete freedom to choose any specialist.
| Insurer | Budget Tier | Standard Tier | Guided Tier | Premium Tier |
|---|---|---|---|---|
| Bupa | Essential Access | Extended Choice | N/A | Extended Choice + London |
| Aviva | Key | Extended | Expert Select | N/A (Included in Extended) |
Scenario: A client in Surrey wants the option of being treated in London. They should choose Bupa's "Extended Choice with Central London" or ensure their chosen Aviva plan includes their preferred London hospital. A client in rural Yorkshire could save money by choosing Bupa's "Essential Access" or Aviva's "Key" list.
Outpatient Cover: The Most Important Choice You'll Make
Outpatient cover pays for the diagnostic stage of your treatment journey—the consultations and tests you have before being admitted to hospital. This can include:
- Specialist consultations
- Blood tests
- MRI, CT, and PET scans
- X-rays and ultrasounds
Limiting your outpatient cover is the single most effective way to reduce your premium, but it comes with a risk. Diagnostic scans can cost over £1,000 each. If your outpatient limit is only £500, you will have to pay the shortfall yourself. (illustrative estimate)
Bupa's and Aviva's Outpatient Options
Both insurers offer similar structures for outpatient cover, allowing you to choose a monetary limit that suits your budget.
- Bupa: Typically offers limits of £500, £750, £1,000, or a fully comprehensive 'Unlimited' option.
- Aviva: Also offers limits, often starting from £0 (meaning you'd use the NHS for all diagnostics), £500, £1,000, or their full cover 'Unlimited' option.
Broker Insight: We find many clients are tempted by the lowest £500 limit to save money. However, for most people, a £1,000 to £1,500 limit offers a much safer balance between cost and coverage. Full unlimited cover provides complete peace of mind but comes at the highest premium. An expert adviser at WeCovr can help you model the cost-benefit of each level.
Price and Premiums: How Do Bupa and Aviva Compare?
This is the million-dollar question, but the answer is always personal. Premiums are calculated based on a range of factors:
- Your Age: Premiums increase as you get older.
- Your Location: Living in or near major cities like London or Manchester costs more.
- Your Chosen Cover: Hospital list, outpatient limit, and any add-ons.
- Your Excess: A higher excess lowers your premium.
- Underwriting: Moratorium is usually the standard.
To give you an idea, here are some illustrative monthly premiums for 2026. These are not quotes and are for example purposes only. They assume a £250 excess and Moratorium underwriting.
| Persona | Bupa (Extended Choice, £1000 Outpatient) | Aviva (Expert Select, £1000 Outpatient) |
|---|---|---|
| 30-year-old, Bristol | £55 | £50 |
| 45-year-old, Manchester | £85 | £78 |
| 60-year-old, London | £170 | £160 |
Observations:
- Aviva's 'Expert Select' option often makes their policies slightly more competitive on price, especially for younger individuals.
- Bupa's price reflects its vast network and brand strength.
- The price gap can widen or narrow significantly depending on the exact cover options chosen. The only way to know for sure is to get a tailored comparison.
Cancer Cover: A Critical Point of Comparison
For most people, cancer cover is the single most important reason to have private medical insurance. Both Bupa and Aviva offer outstanding, comprehensive cancer care that goes above and beyond what is always available on the NHS, particularly regarding access to the latest drugs and therapies.
- Bupa: Their cancer promise is a cornerstone of their offering. On comprehensive policies, there are no time limits on eligible cancer treatment. They provide access to specialist cancer centres and a dedicated support team. Bupa often covers eligible drugs that may not be approved for NHS use due to cost.
- Aviva: Aviva's cancer cover is equally robust. Their 'Cancer Care with Aviva' promise includes paying for chemotherapy, radiotherapy, and surgical procedures in full. They also provide extensive cover for the latest licensed cancer drugs and ongoing monitoring.
The verdict? You cannot go wrong with either insurer for cancer cover. Both provide exceptional care pathways. The decision may come down to preferences for their support services or if one has a partnership with a specific cancer centre you'd prefer to use.
Mental Health Support: Bupa vs Aviva
Awareness of mental health has grown, and insurers have responded. Both Bupa and Aviva have made mental health support a key part of their modern policies.
- Bupa: Provides access to a 24/7 mental health helpline and their 'Bupa Mental Health Hub'. Policies typically cover a number of talking therapy sessions as standard. You can also choose to add more extensive cover for inpatient and outpatient psychiatric treatment.
- Aviva: Has a strong digital-first approach. Members get access to the 'Aviva A&W' wellbeing app and a digital GP service, which can be a first port of call. Their core policies often include good limits for outpatient psychiatric treatment, making them a very strong contender in this area.
Scenario: An employee is suffering from burnout and anxiety. With either Bupa or Aviva, they could access a digital GP, be referred to a therapist for talking sessions, and have the costs covered up to their policy limits, all without a long wait.
Member Benefits and Digital Health Services
Your policy is more than just a promise to pay for treatment. It's also about the day-to-day support and digital tools that help you stay healthy.
| Insurer | Digital GP | Main App | Wellness Perks |
|---|---|---|---|
| Bupa | Digital GP service available via the Bupa Touch app. | Bupa Touch App (manage policy, make claims) | Access to health information, rewards, and health assessments. |
| Aviva | Aviva Digital GP (provided by Square Health). | Aviva A&W App (wellbeing) & MyAviva (policy) | Discounts on gym memberships, health tracking, and wellbeing support. |
