TL;DR
No single insurer is right for everyone. The policy that suits you depends on the cover you need, the hospitals you want, your budget and your medical history. This guide compares the main UK health insurers and the features that make the biggest difference when you claim.
Key takeaways
- Decide what you need covered first: cancer, outpatient diagnosis, mental health and therapies vary most between policies.
- Hospital lists and guided consultant options are the main way insurers keep prices down.
- Moratorium and full medical underwriting treat pre-existing conditions differently.
- Compare like for like: the same excess, outpatient limit and hospital list across insurers.
- The cheapest quote is not always the best value if it leaves out cover you are likely to need.
Searching for the "best" private health insurance usually means looking for the policy that gives you the cover you are most likely to need, at a price you can keep paying. That answer is different for a 30-year-old who wants fast physiotherapy and a 60-year-old whose main concern is cancer treatment.
This guide explains how to judge a policy, then summarises the main UK insurers so you can see where they differ.
Start with what you want the policy to do
Before comparing insurers, decide which of these matter most to you:
- Fast diagnosis: outpatient cover for consultations, tests and scans before any hospital admission.
- Cancer treatment: whether cover is comprehensive, how drugs not routinely available on the NHS are treated, and whether there are time or money limits.
- Mental health: many basic policies exclude it or cap it; comprehensive cover varies.
- Therapies: physiotherapy, osteopathy and chiropractic treatment, often with session limits.
- Hospital choice: whether you need specific hospitals, including central London.
- Digital GP: most insurers now include a remote GP service, but how it links to referrals differs.
The features that make the biggest difference when you claim
Cancer cover
Cancer is where policies differ most and where costs can be highest. Look at whether treatment is covered in full, how long drugs are funded, whether palliative care is included, and what happens if treatment is not approved by NICE. Some policies limit cancer cover on cheaper plans.
Outpatient limits
Outpatient cover often pays for the steps that lead to a diagnosis. A low limit can run out after one consultation and an MRI. Check the limit against typical costs: a private MRI of one body part is commonly a few hundred pounds. See private MRI scan costs.
Hospital lists and consultant choice
Insurers use lists to manage costs. A "guided" option, where the insurer gives you a shortlist of consultants or hospitals, usually lowers the premium. If having a free choice of specialist matters to you, check whether the policy allows it.
Underwriting
With moratorium underwriting there is no medical questionnaire, but recent pre-existing conditions are excluded until you go a set period on the policy without symptoms, treatment or advice for them. With full medical underwriting, you disclose your history up front and the insurer confirms exclusions at the start. See moratorium vs full medical underwriting.
The excess and how it applies
An excess applied once per policy year can work out cheaper than one applied per claim if you claim more than once. Check which applies.
The main UK private health insurers
The summaries below describe how each insurer positions its cover. Product details change, so always check the current policy documents.
| Insurer | What it is known for |
|---|---|
| Aviva | One of the UK's largest insurers. Its personal health plan offers a choice of hospital lists, including a guided option to reduce the premium. |
| AXA Health | Major health insurer with modular personal cover, a guided consultant option and a remote GP service. |
| Bupa | One of the best-known UK health insurers. Offers direct access to treatment for some conditions without a GP referral, and a range of hospital list options. |
| Vitality | Combines health insurance with a rewards programme for tracked activity, which can bring discounts and benefits if you engage with it. |
| WPA | A not-for-profit insurer offering flexible plans, including options where you share part of the cost of a claim to lower the premium. |
| The Exeter | A mutual insurer offering personal health insurance alongside income protection. |
| Freedom Health Insurance | A smaller specialist insurer offering flexible personal and international plans. |
There is no single "top" insurer. One may be cheaper for your age and postcode; another may have the cancer or mental health cover you value; a third may include your preferred hospital. Comparing the same level of cover across several insurers is the only reliable way to find the right balance.
How to compare quotes fairly
- Use the same excess for each quote.
- Use the same outpatient limit, or note where they differ.
- Check the hospital list includes hospitals near you.
- Compare cancer cover wording, not just the headline.
- Ask how the insurer handles pre-existing conditions and switching from another insurer.
- Look at how premiums have changed at renewal and what affects them, such as claims or a no-claims discount.
How much does it cost?
As a rough guide, a healthy adult in their 30s on mid-range cover might pay somewhere around £45 to £110 a month, rising with age and with fuller cover. The private health insurance cost guide explains prices by age and what changes them.
Families and businesses
Family policies can be cheaper per person than separate policies. See family private health insurance costs. If you run a business, group schemes may offer better terms on pre-existing conditions for larger groups, but employer-paid cover is usually a taxable benefit. See company health insurance and P11D tax.

What is the best health insurance company?
There is no single "best" health insurance company for everyone, as the most suitable provider depends entirely on your individual circumstances, budget, and healthcare priorities. Rather than looking for an overall winner, it is usually more helpful to look for the company that offers the right balance of cover and cost for your specific needs.
While the main UK insurers offer similar core inpatient treatments, they often differ significantly in how they structure their policies. When comparing providers, you may notice variations in:
- Outpatient cover: How insurers limit consultations, diagnostic tests, and therapies.
- Hospital networks: Whether a provider's standard list includes your preferred local private hospitals, or if you need to upgrade your policy to access certain facilities.
- Underwriting rules: How different companies assess and apply exclusions for pre-existing medical conditions.
- Additional benefits: Extras such as virtual GP access or wellness rewards, which are usually available to eligible customers and subject to specific terms.
It is important to remember that no health insurance company covers everything. All providers apply standard exclusions, which typically include chronic conditions, cosmetic surgery, and normal pregnancy. Furthermore, private medical insurance does not cover emergency treatment; in a medical emergency, you should always call 999 or go to your nearest A&E.
Ultimately, the cover you receive will be subject to underwriting, eligibility, policy terms, and the excess you choose. Because premiums are reviewable and can rise over time, speaking to a specialist at WeCovr, an FCA-regulated broking firm, or one of its broker partners can help you compare options from a range of UK insurers to find a policy that aligns with your requirements.
