Private medical insurance in the UK: cover and costs explained

Summary: Private medical insurance can help pay for eligible private treatment, usually for acute conditions, but cover depends on the policy. Before choosing, compare outpatient benefits, hospital access, excesses, exclusions and how the insurer assesses medical history. It supplements rather than replaces NHS care, and premiums and claims decisions depend on the terms and your circumstances.

Private medical insurance can help you access eligible private diagnosis and treatment, but a policy is not a promise to cover every health need. Its value depends on the benefits, exclusions and hospitals that suit your circumstances. For a starting point, compare our best private medical insurance in the UK information with the care you want covered.

Take-up is one sign of how many people consider this type of cover, but it does not show whether a particular policy will suit you. The FCA’s 2024 Financial Lives survey found that 14% of UK adults held private medical insurance. Policies differ, so check the wording and ask how the insurer will assess your application before deciding.

What does private medical insurance cover?

Most UK private medical insurance is designed to help pay for eligible treatment for acute conditions, meaning conditions that arise after cover starts and may respond to treatment. The exact definition and benefits depend on the policy. Read the policy documents rather than assuming that a condition or service is included.

Many policies include hospital treatment for inpatient or day-patient care, where treatment involves a hospital bed. Outpatient benefits may cover consultations, diagnostic tests and scans, but these can be limited by an annual cap or offered as an optional extra. Check whether the policy covers the full pathway from consultation and diagnosis to treatment, or only certain stages.

Other benefits, such as cancer treatment, mental health support, physiotherapy or access to particular hospitals, vary between policies. Check benefit limits, referral rules and any approved provider lists. The Association of British Insurers reported in January 2026 that 6.5 million people had health insurance in 2024, including 4.8 million covered through workplace policies. These market figures describe overall cover, not what an individual policy will pay.

Private medical insurance generally does not pay for every healthcare need. Routine care, long-term management of chronic conditions and treatment for pre-existing conditions may be excluded or restricted, depending on the policy and underwriting. Ask the insurer to confirm any uncertain benefit in writing before you rely on it.

How does private cover relate to NHS care?

Suppose your doctor refers you for a planned consultation or diagnostic test. Depending on your policy and the insurer’s authorisation, you may be able to use private care for eligible treatment. If the treatment is not covered, you can discuss NHS care or other options with your healthcare professional.

Private medical insurance is an additional route for eligible private care, not a replacement for the NHS. NHS services remain important for emergency care, GP care and ongoing health needs. Private cover does not automatically guarantee a shorter wait, a specific consultant or a particular treatment.

Whether a policy is useful depends on what it covers and what you value, such as outpatient diagnosis, hospital choice or the level of excess you can afford. MoneyHelper guidance also emphasises that cover depends on the policy you buy and the provider. Compare the policy’s actual terms with your needs, not just its headline benefits.

What affects premiums and out-of-pocket costs?

Age, location, cover level, hospital access, underwriting and optional benefits can all affect the premium. The size of your policy excess matters too: a higher excess may reduce the premium, but means you pay more towards eligible claims before the insurer contributes. Check whether the excess applies once per year, per claim or per person.

Restricting the hospital list or choosing a lower outpatient limit may help make a policy more affordable, but can reduce your options when you need care. Consider the likely cost of using benefits that are capped, excluded or not included. A lower premium does not necessarily mean better value if important parts of your care pathway are not covered.

For a closer look at the factors involved, read our guide to private medical insurance costs in the UK. Compare like with like: check the same excess, hospital access, outpatient benefits and underwriting basis across any quotes you review. Premiums are specific to the policy and your circumstances, so a general example cannot establish your own price.

How are pre-existing conditions and exclusions handled?

Your medical history can affect what an insurer is willing to cover. Under moratorium underwriting, certain pre-existing conditions may be excluded under the policy’s rules. With full medical underwriting, the insurer considers the medical information you provide before setting any specific exclusions or terms. Definitions and time periods vary, so check the actual wording.

Answer application questions accurately and disclose relevant information as requested. If a condition or symptom is excluded, ask what that means in practice, including whether related consultations, tests or treatment would also be outside cover. Do not assume that a condition becomes covered unless the insurer confirms this under the policy terms.

Changing insurer also needs care. Do not assume a new policy will continue cover for a condition accepted by your current insurer. Ask both providers about exclusions, any continuity terms and how a switch could affect existing cover before cancelling a policy.

If your medical history makes options difficult to compare, our referral service can connect you with a specialist to discuss possible underwriting approaches. We can help you explore the questions to raise, but cover remains subject to the regulated provider’s advice and decision.

What should you compare before choosing a policy?

Before choosing, look beyond the monthly premium. Compare the key terms that determine what you can claim, where you can receive treatment and how much you might pay yourself.

• Hospital list: Check whether suitable hospitals and consultants near you are included.

• Outpatient cover: Review consultation, scan and diagnostic limits, including any annual cap.

• Excess: Confirm how much you pay and when it applies.

• Exclusions: Read the terms for pre-existing conditions, chronic care and any other treatment restrictions.

• Claims process: Check referral and authorisation requirements, and ask what to do before arranging treatment.

For help thinking through these trade-offs, see our guide to choosing a private health insurance plan. Where you want advice, check who will provide it and who makes the final decision. An intermediary may introduce you to a specialist, while the insurer or regulated provider determines the available terms and cover.

How do claims and treatment approval work?

When you need treatment, first check your policy’s process. You may need a GP referral, insurer approval or both before booking a consultation, test or procedure. Ask the insurer to confirm what is authorised, which providers you can use and whether any excess or benefit limit applies.

Approval for one stage does not necessarily mean that every later service is covered. For example, a consultation may be authorised while a related test or treatment requires a separate decision. Keep records of approvals and ask the insurer before proceeding if your care plan changes.

The scale of private care use does not predict an individual’s waiting time. PHIN’s June 2026 market update reported that UK admissions funded by private medical insurance reached a record level in 2025, up 1% on 2024. That market-wide change does not guarantee that a particular person will receive quicker care, or that a policy will approve a specific claim.

For a step-by-step explanation, read how private medical insurance works. Keep the insurer’s contact details and policy documents available, and confirm coverage before incurring costs. If a claim is declined or limited, ask the insurer to explain the reason and the process for challenging the decision.

Make the policy wording part of your decision

The right policy depends on the care you want help paying for, the exclusions you can accept and the costs you could manage yourself. Compare benefits, excesses, hospital access and underwriting terms side by side. Read the full policy wording and confirm uncertain details with the insurer before you buy. Private medical insurance in the UK can supplement NHS care, but it does not guarantee that every treatment will be covered or approved.
