Bupa vs Aviva health insurance: compare the cover you would use
Compare Bupa’s guided care and hospital networks with Aviva’s Expert Select, then check outpatient allowances and mental-health options.
Check hospital access and outpatient cover first. Aviva Expert Select offers hospital choices when you claim. Its fixed hospital-list options work differently. With Bupa, access depends on your chosen network and whether you select guided care. Both products can cover private diagnosis. Your chosen benefits set the limits.
Which products does this comparison cover?
This guide covers UK plans for individuals. It does not compare work schemes or overseas cover. Bupa Treatment and Care differs from Comprehensive: it does not pay for private diagnosis before treatment. Bupa’s product comparison explains the difference.
Bupa and Aviva: selected benefits compared
| Feature | Bupa By You | Aviva Healthier Solutions |
|---|---|---|
| Diagnosis | Choose Comprehensive if private diagnosis is required. | Full outpatient cover, a shared £500 or £1,000 allowance, and other reduced-cover options are listed in the cited terms. MRI, CT and PET scans at a diagnostic centre remain separate from the £500/£1,000 allowance. |
| Guided access | Where guided care applies, follow the open-referral network requirements. | Expert Select offers hospital choices when you claim, based on your needs. |
| Wider access | Check your chosen network and consultant eligibility. | Compare the available hospital-list option with Expert Select. |
| Mental health | Check the benefit schedule and applicable limits. | The optional inpatient/day-patient mental-health benefit includes up to 28 days’ accommodation and nursing per member, per policy year; specialist fee limits still apply. |
| Excess and allowances | The excess does not count towards the benefit allowance used. | The excess does not contribute to a monetary benefit limit. |

Expert Select or a hospital list?
How much does choosing your own consultant matter to you? Would you be happy to ask the insurer first and follow the route it offers? Or do you want to use a certain doctor or hospital? Decide this before comparing prices.
Ask both insurers: “If my GP refers me to this specialist at this site, what would this quote cover?” Get a clear answer. The size of the advertised network alone will not tell you. See guided versus non-guided cover.
Do both quotes fund the same diagnostic route?
List each stage: first specialist visit, tests, major scans, results appointment and treatment. Mark which benefit pays at each stage and what limit applies. If the quote is unclear, leave a blank and ask the insurer to explain.
This matters when a cheaper quote has less outpatient cover. Check which visits or tests you would need to get through the NHS or pay for yourself. “Comprehensive” does not mean every service has unlimited cover.
Which offers better value?
Compare the full first-year price after any offer. Ask how the price is worked out after that. Does the quote include a starting discount that reduces later? An offer may be good value, but it will not tell you next year’s price.
Think about what you might need to pay yourself. A higher excess may lower the premium, but you must be able to pay that share of a claim. A lower excess may suit you if you want less to pay when you claim. Our excess calculator compares your own quotes. It does not assume either insurer’s price.
Switching from one to the other
Aviva says you are unlikely to meet its medical-history switch rules if you are having treatment and want it to continue. It may offer new underwriting instead. This is a fresh check of your medical history and would not cover the pre-existing condition. Get the decision in writing before cancelling Bupa or any other policy. Aviva switching information.
Ask for a written list of lost benefits, new exclusions and changes to treatment access. If the cover differs in key ways, make that clear. It is not the same policy for less.
What to send for a useful review
- Your current renewal and membership certificate, if already insured.
- Any hospitals or consultants that matter to you.
- Your preferred excess and outpatient level.
- The benefits you regard as essential, such as cancer, mental health or therapies.
- Relevant medical details through the secure application or adviser process.
Include your current policy in the comparison, particularly if you have ongoing treatment.
Common questions
Is Aviva always cheaper than Bupa?
No. Prices depend on the person applying. Compare quotes with similar benefits, excess and hospital access. Check the medical-history terms each insurer has agreed too.
Is Expert Select the same as a fixed hospital list?
No. Aviva offers hospital choices when you claim, based on the tests or treatment you need. Check the route before you arrange care.
Should I switch just because the new premium is lower?
Compare medical-history acceptance and benefits first. A lower premium can accompany a change in outpatient limits, hospital access or other cover.
