UK Health Insurance Providers: How to Compare

UK health insurance providers are the insurers that sell private medical insurance (PMI), a policy that pays for private diagnosis and treatment of new, short-term (acute) conditions that develop after your cover starts. The main names most people compare are Aviva, AXA Health, Bupa, Vitality, WPA, The Exeter and Freedom Health Insurance. PMI sits alongside the NHS rather than replacing it, and it does not cover emergencies, chronic long-term conditions or pre-existing conditions in most cases.

Choosing between providers comes down to a few practical decisions: the cover level, the excess you pay per claim, how your medical history is assessed (moratorium versus full medical underwriting), the hospital list you can use, and whether you add cancer, mental health or outpatient benefits. Those choices move the price far more than the provider’s name does.

Free Price Compare has partnered with Health Window to compare private medical insurance across leading UK insurers in one place, and we source market context from the ABI, FCA and NHS.

Who are the main UK health insurance providers?

The main UK health insurance providers are Aviva, AXA Health, Bupa, Vitality, WPA, The Exeter and Freedom Health Insurance, all authorised and regulated by the FCA. These insurers underwrite the private medical insurance most UK households and businesses buy. They differ mainly in their hospital lists, how they handle outpatient and cancer cover, and the wellness extras they bundle in.

Across the market, 6.5 million people were covered by health insurance in the UK in 2024, up 4% on 2023, according to the ABI (published January 2026). Of those, 4.8 million were covered through workplace schemes, according to the ABI (published January 2026), which shows how much PMI is bought by employers rather than individuals.

No single insurer is the “best” for everyone. Bupa and AXA Health run large provider networks; Vitality links premiums to a wellness programme with discounts for activity; WPA is a not-for-profit insurer; The Exeter and Freedom tend to suit people wanting flexible, modular cover. The right choice depends on your health history, budget and which hospitals you want access to.

Figures are indicative and may change.

How much does private health insurance cost per month?

Cover starts from £23 a month with us, with WPA promotional cover ranging from £22.90 to £38.58 a month across single, couple and family tiers. That makes private health insurance cost roughly £5 to £9 a week at the lower end for a non-smoker on Treatment Cover, before any add-ons or network upgrades. Your actual premium depends on your age, where you live, your excess and the cover level you choose.

Premiums may vary depending on each individual’s circumstances. £22.90/month (about £5.28/week) for a 29-year-old non-smoker with Treatment Cover (£100 excess). £25.17/month (about £5.81/week) for a 35-year-old non-smoker with Treatment Cover (£250 excess). £38.58/month (about £8.90/week) for a 50-year-old non-smoker with Treatment Cover (£250 excess). All prices under WPA promotion. All include limited cancer cover and a £50,000 Treatment Cover limit per year. These are indicative UK examples; prices correct as of May 2026 and vary by individual circumstances, location, exclusions and plan terms.

For market context, UK health insurers processed a record £4 billion in individual and workplace private medical insurance claims in 2024, according to the ABI (published January 2026), which reflects how much treatment PMI actually funds. Prices rise with age because older policyholders are statistically more likely to claim, so a comprehensive plan at 60 costs considerably more than the same plan at 30.

The cheapest health insurance UK option is rarely the one with the lowest headline figure. A low premium often means a smaller hospital list, a higher excess or limited outpatient and cancer cover. Reading the policy wording matters more than the monthly price alone.

What does private health insurance actually cover?

Private health insurance covers the private diagnosis and treatment of new, acute conditions that arise after your policy starts, typically including consultations with specialists, diagnostic tests, surgery and private hospital stays. Most plans build out from an inpatient and day-patient core, with outpatient cover, cancer cover and mental health cover added as modules. The exact benefits vary by provider and the tier you choose.

PMI does not cover everything. It generally excludes A&E and emergencies (which the NHS handles), the ongoing management of chronic long-term conditions, and pre-existing conditions, which are usually excluded or assessed through underwriting. It is not a replacement for the NHS; it sits alongside it to give faster access to private treatment for eligible acute conditions.

Common elements worth checking before you buy:

• Inpatient and day-patient cover for surgery and hospital stays
• Outpatient cover for scans, tests and specialist appointments (often capped or optional)
• Cancer cover, which ranges from limited to full on different plans
• Mental health cover, which may be excluded or added as a module
• The hospital list you can use, from a budget network to a full private list

Private healthcare providers (the hospitals and clinics) are separate from your insurer. Independent data on private hospitals and consultants is published by the Private Healthcare Information Network (PHIN), which can help you understand where you could be treated under a given plan.

Moratorium vs full medical underwriting explained

Underwriting is how an insurer assesses your medical history to decide what it will and will not cover, and PMI uses two main methods: moratorium and full medical underwriting. Both affect how pre-existing conditions are treated, so the choice shapes your cover as much as the premium does.

Moratorium underwriting requires no medical forms upfront. The insurer excludes any condition you had symptoms of, advice on, or treatment for in a set period before the policy start (commonly the previous five years). If you then go a continuous period (often two years) without symptoms, treatment or advice for that condition, it can become eligible to claim for. It is quick to set up but leaves some uncertainty about what is covered until you claim.

Full medical underwriting means you disclose your medical history when you apply, and the insurer tells you in writing exactly which conditions are excluded before cover starts. It takes longer to arrange but gives certainty from day one about what is and is not covered.

Neither method covers pre-existing conditions as standard. A specialist health insurance broker can help if your history is complex, which is why many people with past medical issues seek advice rather than buying direct. If you already have cover for other risks, it can be worth reviewing related protection such as life insurance and mental health considerations at the same time.

Which health insurer is cheapest for my age?

No single insurer is cheapest at every age, because providers price differently across age bands, hospital lists and excess levels. The lowest-priced provider can differ by age, cover level and personal circumstances, so comparing quotes for your own age and postcode matters more than following a general ranking. That is why comparing quotes for your own age and postcode matters more than following a general ranking.

Age is one of the strongest price factors in PMI. Premiums tend to rise steadily from your 30s and climb more sharply past 50, reflecting higher claim likelihood. Two people of the same age in different parts of the UK can also see different prices, because treatment costs and claim patterns vary by region.

To find cheap health insurance UK cover for your age without losing the protection you need, compare like-for-like: the same excess, the same hospital list and the same cancer and outpatient terms across providers. Comparing on price alone across different cover levels gives a misleading result.

Is there an age limit on private health insurance?

Most UK health insurance providers will cover adults well into later life, and many have no upper age limit for taking out a new policy, though terms and premiums change with age. Some plans are designed specifically with older applicants in mind, and premiums for people in their 60s and 70s are substantially higher than for younger adults because the likelihood of claiming is greater.

Private medical insurance in retirement is a common search, and it remains available, but it pays to check two things: whether the provider caps the age at which you can start a new policy, and how the premium is likely to rise year on year. Some insurers also offer age-related benefits or modular plans that let older policyholders control cost by adjusting the cover level or excess.

If budget is the main concern in later life, a higher excess or a smaller hospital network can bring the premium down while keeping the core inpatient protection. Comparing several providers is the practical way to see which one prices your age band most competitively.

How does PMI affect the speed of treatment versus the NHS?

Private medical insurance can give faster access to private diagnosis and treatment for eligible acute conditions, but it does not change emergency or urgent care, which the NHS provides for everyone. PMI is used for planned, non-emergency treatment of new conditions, such as seeing a specialist or arranging a scan or elective operation privately rather than waiting for an NHS appointment.

PMI is not a substitute for the NHS. Emergencies, A&E, maternity care, and the ongoing management of chronic conditions remain NHS services. For any urgent symptom or medical concern, contact your GP or call NHS 111; this article is about insurance comparison, not clinical advice.

How much faster private treatment is depends on your condition, the provider’s network and the hospital’s availability, so no insurer can guarantee a timescale for every case. What PMI consistently offers is a different route for eligible acute conditions, alongside the NHS rather than instead of it.

How do UK buyers decide between providers?

UK buyers usually decide between health insurance providers by weighing five things: cover level, excess, underwriting method, hospital list and price. Working through these in order narrows the field far faster than comparing brand names, because the same provider can be competitive or expensive depending on how you configure the plan.

• Cover level: budget Treatment Cover versus comprehensive inpatient and outpatient plans
• Excess: a higher excess lowers the premium but raises what you pay per claim
• Underwriting: moratorium for speed, full medical underwriting for certainty
• Hospital list: a smaller network is cheaper; a full list costs more
• Add-ons: cancer, mental health and outpatient modules change both cover and price

Many people with a complex medical history choose to use a specialist broker rather than buying direct, because brokers can explain how different insurers treat past conditions. Comparing across a panel of leading UK insurers in one place, as Free Price Compare does through its Health Window partnership, lets you see how each decision moves the price before you commit. Protections like mental health and life cover are also worth reviewing alongside PMI.
