Comparing two major UK insurers on hospital lists, outpatient cover, and pricing
When you're deciding between Bupa and Aviva for your private health cover, you're looking at two of the most established and respected providers in the UK market. Both offer excellent levels of care, but they differ in crucial ways that can significantly impact your experience and your wallet.
This comparison will cut through the marketing noise and focus on the three pillars of any great PMI policy:
- Hospital Access: Where can you actually be treated?
- Outpatient Cover: How are you covered for diagnostics and consultations before a hospital stay?
- Pricing & Value: What will it cost, and what do you get for your money?
Let's break down how they stack up.
Bupa vs Aviva: At a Glance Comparison for 2025
For those short on time, this table provides a high-level overview of the key differences between Bupa's 'By You' policy and Aviva's 'Healthier Solutions' policy.

Understanding the Fundamentals: What is Private Medical Insurance?
Before we dive deeper, it's vital to be clear on what private medical insurance (PMI) is designed for.
PMI is for acute conditions. An acute condition is a disease, illness, or injury that is likely to respond quickly to treatment and allow you to return to your previous level of health. Think cataracts, joint replacements, or hernia surgery.
Crucially, standard UK private medical insurance does not cover:
- Pre-existing conditions: Any illness or injury you had before taking out the policy will be excluded, at least initially.
- Chronic conditions: Long-term conditions that cannot be cured, only managed. This includes things like diabetes, asthma, and high blood pressure.
PMI is your key to bypassing long NHS waiting lists for eligible treatments, gaining access to private hospitals, and getting specialist care quickly.
Core Cover Breakdown: What’s Included as Standard?
Both Bupa and Aviva build their policies on a foundation of "core cover." This is the non-negotiable part of your plan that covers you if you need to be admitted to a hospital.
Both Bupa and Aviva's core policies will typically cover:
- Hospital Charges: The cost of your room, nursing care, and meals in a private hospital.
- Specialist Fees: Fees for the surgeons and anaesthetists involved in your treatment.
- Diagnostic Tests: Scans like MRI, CT, and PET when you are an inpatient.
- Cancer Treatment: Both providers include extensive cancer cover for chemotherapy, radiotherapy, and surgery as part of their core offering.
- Ambulance Costs: For private ambulance transport to a private facility when medically necessary.
The standard cover for both is excellent and broadly similar. You will not be left wanting for inpatient care with either provider. The real choice and customisation come from the hospital lists and optional extras.
Hospital Lists Compared: Where Can You Be Treated?
A common mistake is assuming all private hospitals are included in every policy. They are not. Insurers use "hospital lists" or networks to manage costs. Choosing the right list is a balance between choice and price.
Bupa Hospital Lists
Bupa operates a tiered system designed to offer different levels of access and price points:
- Essential Access: Bupa's value-oriented list. It includes a good network of private hospitals across the UK but excludes some of the premium-priced facilities, especially in Central London.
- Extended Choice: This is the most popular option. It provides a comprehensive list of several hundred private hospitals and clinics nationwide.
- Extended Choice with Central London: The premium tier. This adds the exclusive and expensive hospitals in Central London (e.g., The Lister, The London Clinic). This option carries a significant price increase.
Aviva Hospital Lists
Aviva also uses a tiered approach, though with different naming conventions:
- Key: Aviva's budget-friendly list. It's more restricted than Bupa's Essential Access and relies heavily on a network of private wings within NHS hospitals and select private hospital groups.
- Extended (Hospital Options): This allows you to choose from a wide range of national private hospitals. You can also opt for their "Trust" network, which focuses on private patient units in NHS Trust hospitals, often at a lower premium.
- London Upgrades: Like Bupa, Aviva requires you to add a specific upgrade to get access to the top-tier London hospitals.
Adviser's Tip: Don't just pick the cheapest hospital list. Before you buy, check that your preferred local private hospital is included in the list you choose. People living outside major cities can sometimes find their nearest facility is not on a budget list, making the policy less useful. An adviser at WeCovr can check this for you in minutes.
Outpatient Cover: The Most Important Customisation
This is arguably the most critical decision you will make when building your policy. Outpatient cover pays for the diagnostic journey before you are admitted to hospital.
- What it covers: Specialist consultations, blood tests, and diagnostic scans (like MRI or CT) that do not require a hospital bed.
- Why it's important: Without it, you would have to pay for all your pre-admission diagnostics yourself, which can run into thousands of pounds, or rely on the NHS for this stage.
Bupa Outpatient Options
Bupa gives you a clear choice:
- No Outpatient Cover: Relies on the NHS for all diagnostics. The cheapest option, but can lead to long waits.
- Monetary Limits: You can choose a limit of £500, £750, or £1,000 per policy year. This is a popular middle ground.
- Full Outpatient Cover: No financial limit on eligible consultations and diagnostics. The most comprehensive and expensive option.
Aviva Outpatient Options
Aviva's approach is slightly different:
- Standard Outpatient (£1,000 limit) (illustrative): Many 'Healthier Solutions' policies come with a £1,000 outpatient limit as a default.
- Full Outpatient Cover: You can upgrade to have unlimited cover for eligible outpatient treatment.
- Reduced Options: You can also choose to reduce or remove the outpatient limit to lower your premium.
Real-Life Scenario: Imagine you have persistent knee pain.
- You see a GP who refers you to an orthopaedic specialist.
- Outpatient: The specialist consultation (£250), an MRI scan (£800), and a follow-up consultation (£150) are all outpatient services. Total: £1,200.
- Result: With a £1,000 outpatient limit, you'd have a £200 shortfall to pay yourself. With Full Cover, it would all be paid. This is why choosing the right limit is vital.
Cancer Cover: A Critical Comparison
Peace of mind around cancer treatment is a primary reason many people buy private health insurance. The good news is that both Bupa and Aviva provide outstanding, market-leading cancer cover as standard.
Key Features of Both Bupa and Aviva's Cancer Cover:
- Full Cover for Treatment: No financial or time limits on eligible cancer surgery, chemotherapy, and radiotherapy.
- Advanced Therapies: Access to specialist treatments and drugs that may not be available on the NHS.
- Ongoing Monitoring: Cover for regular check-ups following your treatment.
- Support Services: Dedicated cancer support teams, helplines, and access to nurses.
The Nuances
- Bupa: On their 'Comprehensive' plan, full cancer care is included by default. They have a strong reputation for their Bupa Cancer Promise and support networks. They provide access to breakthrough drugs and treatments, often as soon as they are licensed.
- Aviva: Aviva's cancer cover is equally extensive. Their 'Expert Select' option gives you access to a curated list of cancer specialists and hospitals. They also have a strong focus on providing access to the latest licensed treatments.
Broker Insight: While both are excellent, there can be subtle differences in their lists of approved experimental drugs or access to specific niche treatments. For clients with specific concerns, a broker can examine the fine print of each policy to ensure the best possible fit.
Mental Health Cover: A Growing Priority
Awareness of mental health has rightly grown, and insurers have responded.
- Bupa: Bupa has made mental health a cornerstone of its offering. Many of its policies include a good level of mental health cover as standard, covering both inpatient and outpatient psychiatric treatment. They provide direct access to their mental health support network without needing a GP referral.
- Aviva: Aviva also offers a solid range of mental health benefits. While it's often an optional add-on rather than standard, the cover is comprehensive once selected. Their mental health pathways are designed to get members fast access to the right support, from therapy to specialist consultations.
For those who see mental health support as a top priority, Bupa's "included as standard" approach on their comprehensive policies may be more appealing. However, Aviva's optional cover is just as robust if you choose to add it.
Pricing and Excess: How Much Will It Cost?
Price is influenced by your age, location, medical history, and the level of cover you choose. Central London postcodes are always more expensive than rural ones.
To give you an idea, here is an illustrative table of monthly premiums. These are examples only – your quote will be personal to you.
| Persona | Bupa 'By You' | Aviva 'Healthier Solutions' | Policy Details |
|---|---|---|---|
| 35-year-old, Manchester | £75 | £68 | £250 excess, £1,000 outpatient, Extended hospital list |
| 50-year-old, Bristol | £120 | £110 | £500 excess, £1,000 outpatient, Extended hospital list |
| 45-year-old, London | £155 | £145 | £250 excess, Full outpatient, London hospital list |
Illustrative prices as of Jan 2025. Actual premiums will vary.
What is an Excess? An excess is the amount you agree to pay towards a claim each year. A higher excess (£500 or £1,000) will significantly lower your monthly premium. A £0 excess means the insurer pays everything, but your premiums will be higher. Both Bupa and Aviva offer a flexible range of excess options from £0 up to £1,000 or more.
Generally, Aviva can often come in slightly cheaper on a like-for-like basis, particularly for younger customers or those looking for a more modular policy. Bupa is often perceived as the premium brand, and its pricing can sometimes reflect that. However, the only way to know for sure is to get a direct comparison quote.
Digital Tools and Member Benefits
Your policy isn't just about hospital treatment. Both insurers offer a suite of modern digital tools.
- Digital GP: Both Bupa and Aviva provide 24/7 access to a virtual GP via an app. This is incredibly convenient for getting quick medical advice, prescriptions, or referrals without waiting for a face-to-face appointment.
- Wellness Apps & Discounts: Both providers offer member discounts on gym memberships, health screenings, and other lifestyle products.
- WeCovr Member Benefits: When you take out a policy through WeCovr, you get complimentary access to our AI-powered calorie and nutrition tracking app, CalorieHero. Plus, our clients often receive exclusive discounts on other types of cover, like life or income protection insurance.
Which is Better for You: Bupa or Aviva? A Broker's Verdict
There is no single "better" insurer; there is only the insurer that is better for you.
Choose Bupa if:
- You value the reassurance of a household brand name.
- You want comprehensive mental health cover included as a core benefit.
- You prefer a straightforward "all-in" comprehensive plan without too many moving parts.
Choose Aviva if:
- You want maximum flexibility to build a policy that fits your exact needs and budget.
- You are price-conscious and want to explore all options to get the most competitive premium.
- You are comfortable with a slightly more restricted hospital list (like their 'Key' network) in exchange for a lower price.
The truth is, comparing these giants on your own can be complex. The best approach is to define your priorities—be it a specific hospital, full outpatient cover, or the lowest possible price—and then compare tailored quotes.
