UK Private Health Insurance: Cover, Costs and How It Works

Summary: UK private health insurance helps pay for eligible private diagnosis and treatment, usually for new acute conditions. What you can claim depends on the policy’s benefits, exclusions, excess and underwriting terms. Compare these details alongside the premium, hospital access and claims process, and remember that private cover works alongside NHS care rather than replacing it.

Would paying a regular premium make private treatment easier to access when you need it? UK private health insurance, also known as private medical insurance, can help cover eligible treatment for new medical conditions. The value depends on the cover you choose and how well it fits your needs. Our guide to private health insurance in the UK explains the essentials for people weighing up their options.

Private medical insurance is optional, and it does not replace the NHS. In 2024, 6.5 million people in the UK had health insurance through individual or workplace policies, according to ABI figures published in 2026. That total describes the market, not whether a policy is right for you. Your decision should start with the treatment you want covered, the exclusions you can accept and the cost you can sustain.

What does private medical insurance do?

Private medical insurance pays towards eligible private healthcare, subject to your policy terms. People often consider it for quicker access to planned diagnosis or treatment, more choice over hospitals or consultants, or a private room during a hospital stay. Benefits differ between policies, so do not assume that a particular appointment, test or treatment is included.

Cover commonly focuses on new acute conditions, meaning illnesses or injuries that arise after the policy starts and respond to treatment. Many policies include inpatient and day-patient treatment. Outpatient consultations, diagnostic tests, therapies and mental health treatment may have separate limits or require optional cover.

Private treatment is not automatically authorised just because you hold a policy. You will usually need to contact the insurer before arranging care, and treatment must meet the policy’s conditions. The NHS remains available for care that your policy excludes, routine services and emergencies.

What may be covered, and what is often excluded?

Imagine that a GP refers you for tests after new symptoms appear. Depending on your cover, your policy might contribute to a specialist consultation, diagnostic scans and eligible treatment. Whether it pays for the whole pathway depends on your benefits, limits, excess and approved providers.

Some policies include cancer diagnosis and treatment, but the exact cover, limits and eligible drugs differ. Outpatient consultations, physiotherapy, psychological support, private GP services, dental care and optical care may be included, limited or offered as additional cover. Check the policy documents rather than relying on a general description of benefits.

Pre-existing conditions are often excluded or assessed under specific underwriting terms. Chronic conditions requiring ongoing care are also commonly outside standard cover. Other common exclusions include emergency treatment, routine pregnancy care and cosmetic procedures, but policy wording determines the details.

Private hospital and clinic admissions in the UK reached 953,000 in 2025, according to PHIN’s 2025 data. This includes private healthcare admissions across the market; it is not a count of insurance claims alone. The figure underlines why it is useful to check which facilities and treatment routes your policy actually includes.

How does underwriting affect pre-existing conditions?

Underwriting is how an insurer assesses your medical history and decides which conditions are covered or excluded. The method affects how much health information you provide at the outset and when the insurer assesses your history. Read the terms carefully, especially if you have had recent symptoms, tests, treatment or medical advice.

With full medical underwriting, you provide medical information when applying. The insurer sets out any personal exclusions before cover begins, giving you more clarity at the start. With moratorium underwriting, you usually provide less health detail upfront. The insurer assesses relevant medical history if you claim, which can leave uncertainty about a condition until then.

A moratorium often excludes conditions connected to symptoms, advice or treatment in a set period before cover starts. Some policies may reconsider a condition after a defined period without symptoms, treatment, medication or advice. The rules and timescales vary, so check the policy wording rather than assuming a condition will become covered.

If you are switching from another insurer, ask whether the new provider can continue your existing medical terms. Continuity arrangements may help preserve cover you already have, but acceptance is not automatic and existing exclusions may carry over. Make sure the new insurer confirms the terms before you cancel your current policy.

What determines premiums, excesses and renewal costs?

Your premium is the price of the policy. It is set according to factors such as your age, where you live, the number of people covered, your level of benefits, hospital access and underwriting. Optional cover can increase the price, while a narrower hospital list or lower benefit limits may change it.

The excess is the amount you agree to contribute towards eligible treatment. A higher excess can reduce the premium, but means you need to pay more when you claim. Check whether it applies per claim, per person or per policy year, and consider whether you could afford it at short notice.

Premiums can change at renewal. Age, claims experience, medical costs and changes to your cover may affect the new price. Compare the renewal offer against the same benefits and exclusions elsewhere, rather than treating the lowest headline premium as the best value.

For a closer look at the factors that influence prices, read our guide to private health insurance costs in the UK. A personalised quote is more useful than a generic average because it reflects your circumstances and chosen cover.

What should you compare before choosing a policy?

A useful comparison starts with the treatment you want covered and the amount you could comfortably pay yourself. In 2024, the FCA’s Financial Lives survey estimated that 14% of UK adults held private medical insurance, according to a published parliamentary answer. That market figure does not establish whether cover suits your household or budget.

Compare policy limits for outpatient consultations, scans, cancer care, mental health support and therapies. Check which hospitals and consultants are available, whether referrals are required, and whether the insurer must approve treatment in advance. Confirm how an excess and any benefit limits apply to each type of care.

Also review how claims could affect renewal pricing, and whether your preferred hospital is on the policy’s list. If you are comparing several options, use the same cover assumptions for each quote. Our overview of the best private health insurance in the UK can help you understand what to look for, while your own needs should guide the final choice.

How does making a claim usually work?

When you notice a health concern, start with your GP or the referral route allowed by your policy. Ask for a referral if required, then contact your insurer before arranging a consultation, test or treatment. The insurer can check eligibility, explain any excess and confirm which hospitals or specialists you can use.

If your treatment is authorised, the insurer often settles eligible bills directly with the provider. You may still need to pay an excess or costs above a benefit limit. Keep the authorisation details and check with the insurer before proceeding if your specialist recommends additional tests or treatment.

Claims can depend on the condition’s history as well as the treatment itself. Under moratorium underwriting, the insurer may need to assess whether a claim relates to a condition you had before cover began. Keep your policy documents available and ask for an explanation if you are unsure what has been approved.

How can a broker referral support your decision?

Comparing policy wording can be difficult when you are balancing medical history, cover limits and budget. A broker consultation can help you discuss those details and explore available policy options. Ask who will provide the final regulated advice, which providers will be considered and whether any fees apply.
