At WeCovr, an FCA-authorised broker that has helped arrange over 900,000 policies of various kinds, we’re here to simplify your decision between the 'big three': AXA, Aviva, and Bupa. This guide gives you the expert insight you need.
When you’re considering private health cover, three names invariably come to the top of the list: AXA Health, Aviva, and Bupa. They are the titans of the UK Private Medical Insurance (PMI) market, collectively holding the majority of policies. But which one is genuinely the best fit for you, your family, or your business in 2025?
This in-depth comparison goes beyond the marketing brochures to give you the clear, unbiased information you need to make an informed choice. We'll break down their offerings on core cover, optional extras, cost, customer service, and those all-important value-added benefits.
For those short on time, here is a high-level overview of how the three giants stack up.
| Feature | AXA Health | Aviva | Bupa |
|---|---|---|---|

Before we dive into the details, let's briefly introduce the contenders. Understanding their background helps contextualise their offerings.
Before comparing any policy, it's vital to understand the fundamental principle of private medical insurance in the UK.
Standard UK PMI is designed to cover acute conditions that arise after you take out the policy.
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 treatment for an infection.
A chronic condition is an illness that cannot be cured but can be managed. Examples include diabetes, asthma, high blood pressure, and arthritis. PMI does not cover the routine management of chronic conditions. It may, however, cover an acute flare-up of a chronic condition.
Critically, PMI also does not typically cover pre-existing conditions – any illness or injury you had symptoms of, or received advice or treatment for, in the years before your policy began (usually the last 5 years). How this is handled depends on your choice of underwriting.
Understanding this distinction is the single most important step to avoid disappointment at the point of claim.
All PMI policies are built around a core offering that covers the most expensive treatments: those requiring a hospital bed. This is known as in-patient and day-patient cover.
Here’s how the standard offerings from AXA, Aviva, and Bupa compare.
| Cover Element | AXA Health (Personal Health) | Aviva (Healthier Solutions) | Bupa (Bupa By You) |
|---|---|---|---|
| In-patient & Day-patient Fees | Covered in full. | Covered in full. | Covered in full. |
| Specialist & Surgeon Fees | Covered in full (with participating specialists). | Covered in full (with participating specialists). | Covered in full (with participating specialists). |
| Diagnostic Tests (In-patient) | Covered in full. | Covered in full. | Covered in full. |
| Cancer Cover (Core) | Comprehensive cancer cover as standard, including chemotherapy, radiotherapy, and surgery. | Extensive cancer cover as standard, including diagnostics, surgery and therapies. | Comprehensive cancer cover as standard for diagnosis and treatment. |
| NHS Cash Benefit | Yes, if you choose to use the NHS for in-patient treatment. | Yes, if you choose to use the NHS for in-patient treatment. | Yes, if you choose to use the NHS for in-patient treatment. |
| Private Ambulance | Included. | Included. | Included. |
Broker Insight: On core cover, the "big three" are remarkably similar. They all provide comprehensive cover for in-patient and day-patient treatment as standard. The real differences emerge when you start looking at optional extras, hospital lists, and value-added services.
This is where you tailor your policy to your needs and budget. The main options are Out-patient cover, Mental Health, Therapies, and Dental & Optical.
This covers consultations and diagnostic tests that do not require a hospital bed. It's one of the most valuable, and most expensive, add-ons.
| Provider | Out-patient Options | Key Features & Broker Notes |
|---|---|---|
| AXA Health | - Full cover - £1,000 limit - £500 limit - No cover | AXA's standard guided option ("Expert Select") includes initial consultations even with no out-patient cover, which is a great value point. Their full cover option is genuinely comprehensive. |
| Aviva | - Full cover - £1,000 limit - £500 limit - No cover | Aviva's limits are straightforward. Choosing a limited out-patient option is a popular way to manage premiums. Be aware diagnostics can quickly use up a £500 limit. |
| Bupa | - Full cover - £1,000 limit - £750 limit - £500 limit - No cover | Bupa offers more granular limits, which can be useful for fine-tuning your premium. Their "Direct Access" service for certain conditions can bypass the need for a GP referral, speeding up access. |
Awareness of mental health has grown, and insurers have responded. This is a key area of differentiation.
| Provider | Mental Health Options | Key Features & Broker Notes |
|---|---|---|
| AXA Health | Included as standard (but can be removed). | Best-in-class. AXA's standard cover is very strong, covering both in-patient and out-patient mental health treatment. Their "Stronger Minds" pathway provides rapid access without a GP referral for certain conditions. |
| Aviva | Standard (limited) or Enhanced add-on. | The standard mental health cover is more basic than AXA's. The "Enhanced" option is required for full psychiatric cover and is a highly recommended upgrade for those concerned about mental wellbeing. |
| Bupa | Included as standard (can be upgraded). | Bupa provides good standard mental health cover. Like Aviva, you may need to upgrade to their "Mental Health and Wellbeing" add-on for the most comprehensive benefits, including more extensive therapy sessions. |
This covers treatment from specialists like physiotherapists, osteopaths, and chiropractors.
Client Scenario: Sarah, a 45-year-old marathon runner, was most concerned about quick access to physiotherapy. For her, a policy with strong, easily accessible therapies cover was more important than a high out-patient limit for consultations. We helped her compare plans that prioritised this need.
This is the million-dollar question. The cost of a private health insurance policy is highly personal and depends on several factors:
To give you an idea, here are some sample monthly premiums.
Sample Monthly Premiums (Mid-Range Cover, £250 Excess)
| Persona | AXA Health | Aviva | Bupa |
|---|---|---|---|
| 35-year-old, Manchester | £65 | £60 | £68 |
| 50-year-old, Bristol | £110 | £102 | £115 |
| 35-year-old, Central London | £85 | £80 | £90 |
| 50-year-old, Central London | £145 | £135 | £150 |

Broker Insight: Aviva often comes out as the most competitive on price for mid-range, flexible policies. AXA can be pricier but often justifies it with more comprehensive standard features, especially for mental health. Bupa's pricing is typically in line with AXA's, reflecting its strong brand and network. Using an independent broker like WeCovr allows you to compare quotes from all these providers side-by-side in minutes, ensuring you don't overpay.
When you buy a policy, the insurer needs to know about your medical history to exclude pre-existing conditions. There are two main ways they do this.
| Underwriting Type | How it Works | Pros | Cons |
|---|---|---|---|
| Moratorium (Mori) | You don't declare your full medical history upfront. Instead, any condition you've had in the 5 years before the policy started is automatically excluded. This exclusion can be lifted if you go 2 full years on the policy without any symptoms, treatment, or advice for that condition. | Quicker to set up. Less intrusive paperwork. | Can lead to uncertainty. A claim may be delayed or rejected while the insurer investigates your medical history to see if it was pre-existing. |
| Full Medical Underwriting (FMU) | You complete a detailed health questionnaire, disclosing your full medical history. The insurer then tells you upfront exactly what is and isn't covered. | Certainty from day one. You know precisely where you stand. Claims process is often smoother. | Takes longer to apply. Can be more intrusive. Exclusions are often permanent. |
Common Client Mistake: Many clients choose moratorium underwriting for speed but don't fully understand the "2-year rule." They mistakenly believe that after 2 years, everything is covered. This is not the case. The condition must be completely dormant (no symptoms, treatment, or advice) for 2 continuous years while you are on the policy for the exclusion to be lifted.
In a competitive market, insurers add extra perks to stand out. These can provide significant day-to-day value.

Navigating the options to secure the best deal can be simple if you follow a few expert tips:
Generally, no. Standard private medical insurance in the UK is designed to cover new, acute conditions that arise after your policy begins. Pre-existing conditions are typically excluded, either for a set period (with moratorium underwriting) or permanently (with full medical underwriting). Some specialist policies may offer cover for pre-existing conditions, but these are rare and more expensive.
The price is usually the same, and can sometimes even be cheaper through a broker. An independent PMI broker like WeCovr can compare the entire market for you, not just one brand. We receive a commission from the insurer you choose, so our expert advice and comparison service is completely free for you. This ensures you get the right policy at the best possible price without the hard sell.
Yes, you can switch providers. It's important to do this carefully to maintain cover for conditions that have developed while you were insured. This can be done using 'Continued Medical Exclusions' (CME) underwriting, where your new insurer agrees to offer the same cover terms as your old one. A broker is invaluable in managing this process to ensure there are no gaps in your cover.
The '6-week option' is a popular cost-saving feature. If you add it to your policy, it means that for any in-patient treatment you need, if the NHS waiting list is less than six weeks, you would use the NHS. If the waiting list is longer than six weeks, your private medical insurance will kick in. As NHS waiting times for many procedures are currently much longer than this, it's a very effective way to lower your premium without significantly impacting your access to private care when you need it most.
The choice between AXA, Aviva, and Bupa is nuanced, with no single right answer. The best private health insurance provider is the one that offers the right protection for your specific needs and budget.
