Ultimately, the "better" insurer is the one that best aligns with your personal needs, location, and budget.

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:
Other standard exclusions include routine pregnancy, cosmetic surgery, and emergency services (A&E is an NHS service).
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 network is known for its breadth and clarity. They typically offer three main tiers:
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 also uses a tiered system, but with a unique twist in its 'Expert Select' option.
| 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 pays for the diagnostic stage of your treatment journey—the consultations and tests you have before being admitted to hospital. This can include:
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.
Both insurers offer similar structures for outpatient cover, allowing you to choose a monetary limit that suits your budget.
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.
This is the million-dollar question, but the answer is always personal. Premiums are calculated based on a range of factors:
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:
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.
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.
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.
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.
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. |
