How we rank the insurers in 2026

Bupa, mental health cover (checked 15 Oct 2026).

What do our brokers see in practice?

Switching insurer without losing cover

For example, a 52-year-old in Leeds switching from Bupa after six years, with a knee investigated two years ago. A cheaper quote on a new moratorium would exclude that knee. Moving on switch (CPME) terms keeps the knee covered as it was; the saving is smaller, but the cover they've paid for carries across.

When the outpatient limit runs out mid-diagnosis

A situation we often see: someone chooses a £500 outpatient limit to keep the price down, then two consultant appointments and an MRI use it up before there's a diagnosis, and they pay the rest themselves. If quick diagnosis is the reason you're buying, I usually suggest at least £1,000 of outpatient cover, or full outpatient cover with a higher excess instead.

A family choosing between two structures

For example, a couple with two young children are quoted lower by Vitality than by Bupa. Vitality applies one claims position to the whole policy, so a child's claim can raise everyone's renewal; Bupa gives each person their own no-claims discount. With small children who are likely to claim, that difference often matters more than the price.

Typical situations described by Andrew Buscu, PMI Advisor. These are examples, not individual cases.

Frequently asked questions

Which is the best private health insurance in the UK in 2026?

It depends on what you need. AXA Health leads our 2026 assessment (4.5 out of 5 on our published method). For specific needs: Bupa for mental health cover, Vitality for active lifestyles, WPA for claims satisfaction and flexible cover, The Exeter for steady renewals, Aviva for price control, General & Medical for hospital list choice, Freedom Health for cancer cover in the core policy. Each pick is backed by a fact the insurer publishes, linked on this page.

Which UK health insurer has the best customer satisfaction?

In Which?'s April 2026 survey of 931 people who had claimed in the last year, WPA scored highest among the PMI insurers we compare (86%), followed by Bupa (77%), AXA Health (76%), Aviva (74%) and Vitality (72%). Samples were small (34 WPA respondents, 269 Bupa) and unweighted, so read them with caution. The Exeter, Freedom and General & Medical were not rated.

Is Bupa better than AXA Health?

Neither is better for everyone. Bupa is stronger on mental health cover, direct access routes and per-person no-claims discounts. AXA is more modular, so family members can choose different cover, and is strong on outpatient diagnostics. Their April 2026 Which? scores were close: 77% (269 respondents) and 76% (186).

What is the cheapest private health insurance in the UK?

The cheapest headline price is often a modular WPA policy, Freedom or General & Medical, but the cheapest at the start is rarely the cheapest after a claim. Excess, hospital list, outpatient limit and how the no-claims discount falls all change what you pay over time.

How do you rank the best health insurers?

We score every insurer on six weighted criteria: depth of cover (25%), cancer and mental health (20%), hospital access (15%), value across ages (15%), claims service (15%) and underwriting and switching (10%). Ties are listed in a fixed order (AXA Health, Bupa, Vitality, WPA, The Exeter, Aviva, General & Medical, Freedom Health). We're paid commission by the insurer you choose, and the method is the same for every insurer.

Do I need a broker to buy private health insurance?

No; every insurer sells direct. A whole-of-market broker compares insurers side by side, explains underwriting and switching terms, and reviews your policy at renewal. PremierPMI's advice is free to you; we're paid commission by the insurer.
