Private health insurance (also called private medical insurance or PMI) is a policy that funds private medical treatment for new, acute conditions that arise after the policy starts. You pay regular premiums and your insurer covers the cost of consultations, diagnostics, and treatment at private hospitals and clinics, bypassing NHS waiting lists for eligible conditions. PMI does not replace the NHS – it sits alongside it. It does not cover pre-existing conditions, chronic illness management, or emergency care. The ABI’s health insurance guidance sets out the regulatory framework and consumer protections that apply to all UK PMI policies.
Key Terms
Private medical insurance (PMI) is a protection policy that funds private healthcare for acute medical conditions – those that are new, curable, and short-term in nature. An acute condition is one that responds to treatment, as opposed to a chronic condition (a long-term illness managed rather than cured, such as diabetes or asthma).
Underwriting is the process by which an insurer assesses what conditions it will and will not cover when you take out a policy. The two main approaches in the UK are moratorium underwriting (automatically excluding conditions you have had in the past five years, with exclusions lifting after two years of symptom-free cover) and full medical underwriting (FMU) (completing a detailed medical questionnaire at application, with all conditions declared assessed individually). Each approach has trade-offs in terms of certainty, cost, and flexibility.
Quick Facts
- ✓UK health insurers processed a record £4 billion in PMI claims in 2024, equivalent to £11 million every single day (ABI)
- ✓6.5 million people in the UK were covered by PMI in 2024, a record high – up 4% from 2023 (ABI)
- ✓The NHS waiting list stood at approximately 7.3 million cases in January 2026, with a median wait of 13.6 weeks, up from 7.8 weeks pre-COVID (NHS England / BMA)
- ✓A healthy non-smoker in their 30s can typically get basic PMI cover for £28-50 per month; comprehensive cover typically costs £80-120 per month
Key Takeaways
- →PMI covers new, acute conditions that arise after the policy starts – it does not cover pre-existing conditions, chronic illness, or emergency care
- →The two main underwriting approaches are moratorium (automatic rolling exclusions) and full medical underwriting (declared conditions assessed individually)
- →Adding a six-week NHS wait option can reduce your premium by 20-30% – you use private care only when the NHS queue exceeds six weeks
- →PMI is available individually, as a family policy, or through an employer – employer-provided PMI is taxable as a benefit in kind
- →For self-employed people, PMI premiums paid personally are not tax-deductible, but can be arranged through a business for the self-employed and is treated as a business expense if structured correctly
The NHS remains free at the point of use for all UK residents, and no one needs private health insurance to access healthcare. But for many people, the growing gap between what the NHS can deliver within an acceptable timeframe and what they need when something goes wrong is what drives the decision to take out a policy. With over 7 million people on NHS waiting lists and the 18-week treatment target met for only around 61% of patients as of early 2026, the practical value of being able to bypass that queue for certain conditions has never been clearer.
This guide explains exactly what private health insurance is, what it covers and what it does not, the key decisions involved in choosing a policy, who it suits, and how it differs from life insurance and income protection. It is a YMYL (Your Money, Your Life) topic and this article presents balanced information only – for a policy matched to your circumstances, we recommend speaking to an FCA-regulated broker.
How Does Private Health Insurance Work in the UK? A Summary
- You choose a policy covering inpatient treatment, outpatient appointments, diagnostics, and any optional extras (dental, optical, mental health, physiotherapy)
- You declare your medical history through either moratorium underwriting (automatic rolling exclusions) or full medical underwriting (individual assessment)
- You pay monthly or annual premiums – the amount depends on age, location, health, cover level, excess, and hospital network chosen
- When you develop a new, acute condition, you contact your insurer for pre-authorisation. They confirm whether the condition is covered before treatment begins
- You see a specialist or consultant at a private hospital or clinic within your policy’s approved network, usually within days rather than months
- The insurer pays the provider directly in most cases, minus any excess you have chosen. You pay nothing further for covered treatment
- The NHS remains available for emergencies, chronic condition management, and anything not covered by your policy. PMI does not replace NHS care
Expert Note – MMC Insurance Specialists | FCA Reg. 916241
“The most common misunderstanding we see is people assuming PMI works like car insurance – you pay in, something goes wrong, you claim. The reality is more nuanced. PMI only covers new, acute conditions that arise after the policy starts. It does not cover the bad back you have had for three years, the blood pressure medication you have been on for five, or the knee that has been playing up since last winter. This is not a flaw in the product – it is the design. PMI is for the unknown future health events you cannot predict or prepare for. For that purpose, it is genuinely valuable. The mistake is buying it and assuming it covers everything, when in reality it covers quite specific things very well.”
What does private health insurance cover in the UK?
PMI covers the diagnosis and treatment of new, acute medical conditions that arise after the policy starts. The core cover includes inpatient treatment (surgery and hospital stays), outpatient consultations and diagnostics, and cancer care. Optional extensions add dental, optical, mental health, physiotherapy, and other therapies depending on the insurer and policy level chosen.
| Cover Area | What Is Included | Typically Standard or Optional? |
|---|---|---|
| Inpatient treatment | Surgery, procedures requiring a hospital stay, nursing care, anaesthetics, theatre costs, accommodation in a private room | Standard – all policy levels |
| Day-patient treatment | Procedures performed under sedation or anaesthesia where no overnight stay is needed (e.g. endoscopy, day surgery) | Standard – all policy levels |
| Outpatient consultations | Specialist consultations, follow-up appointments, and outpatient procedures that do not require admission | Often limited or optional on basic plans |
| Diagnostic tests | MRI scans, CT scans, X-rays, blood tests, pathology – fast diagnostics are one of the most used benefits of PMI | Limited on basic plans; full cover on comprehensive |
| Cancer cover | Chemotherapy, radiotherapy, surgical oncology, and access to drugs not yet available on the NHS. One of the most valued sections of PMI | Standard on most policies but check scope at quote |
| Mental health | Psychiatric consultations, therapy sessions, inpatient psychiatric care. Cover varies enormously between policies | Optional on many policies; included on comprehensive |
| Physiotherapy and therapies | Physiotherapy, osteopathy, chiropractic treatment – usually covered following an acute injury or surgical referral | Optional or limited on standard plans |
| Private GP access | Virtual or face-to-face private GP consultations, often available within 24 hours. Frequently included as a digital benefit | Increasingly standard as a digital benefit (many insurers) |
| Dental and optical | Routine and restorative dental treatment, eye tests, prescription glasses or contact lens contribution | Optional add-on; also available as standalone cash plans |
What does private health insurance not cover?
PMI is not a comprehensive healthcare solution. Its scope is deliberately limited to new, acute, and treatable conditions. Understanding the exclusions before buying is as important as understanding what is covered – many people discover the limitations of a policy only when they come to make a claim.
| What Is Excluded | Why | What Covers It Instead |
|---|---|---|
| Pre-existing conditions | Any condition for which you experienced symptoms, received treatment, or sought advice before the policy start date | NHS. Moratorium policies may cover after 2 years symptom-free |
| Chronic condition management | Ongoing management of long-term conditions (diabetes, asthma, Crohn’s disease, arthritis) is excluded once diagnosed | NHS. Initial diagnosis may be covered; ongoing treatment is not |
| Accident and emergency care | Emergency treatment following accidents, heart attacks, strokes, and similar is provided by the NHS. PMI covers planned treatment only | NHS A&E. Some policies cover private follow-up care after stabilisation |
| Pregnancy and childbirth (routine) | Normal pregnancy, labour, and delivery are not covered. Some policies cover complications of pregnancy | NHS maternity services. Private maternity packages are separate products |
| Cosmetic or elective procedures | Procedures undertaken for cosmetic reasons or personal preference rather than medical necessity | Self-funded privately |
| Infertility treatment | IVF and other fertility treatments are excluded by most standard PMI policies | NHS (subject to criteria) or self-funded. Some specialist policies include it |
| Drug and alcohol dependency | Treatment for addiction and substance dependency is typically excluded from standard PMI | NHS addiction services or specialist private clinics (self-funded) |
| Organ transplants | Excluded by most standard policies due to complexity and cost | NHS transplant programme |
| Experimental or unproven treatments | Treatments not approved by UK regulatory bodies or without an established clinical evidence base | NHS clinical trials or self-funded; some specialist cancer policies provide access to certain novel drugs |
Private health insurance vs NHS: what is the difference in practice?
PMI and the NHS provide healthcare through entirely different mechanisms. The NHS is free, universal, and comprehensive – but is under sustained pressure that has pushed waiting times to record levels. PMI is paid-for, selective in scope, and primarily valued for speed and choice. The two work alongside each other, not instead of each other.
| Factor | NHS | Private Health Insurance |
|---|---|---|
| Cost to patient | Free at point of use | Monthly or annual premiums, plus any agreed excess |
| Waiting times (elective) | Median 13.6 weeks; 18-week standard met for only ~61% of patients (Jan 2026, NHS England) | Specialist consultation typically within days; treatment within weeks for most conditions |
| Diagnostics | 22% of patients waiting over 6 weeks for diagnostic tests (July 2025, Parliament) | MRI, CT, and blood tests typically available within days via outpatient cover |
| Choice of specialist | NHS assigns consultants based on availability and geography | You choose your specialist (subject to the insurer’s approved list and your policy’s consultant access option) |
| Hospital environment | Shared wards typical; facilities vary by trust and location | Private room as standard; higher staff-to-patient ratios; facilities vary by hospital network |
| Emergency care | Comprehensive A&E and emergency services | Not covered by PMI. Emergency care is always NHS |
| Chronic illness management | Long-term management of diabetes, asthma, heart disease, and other chronic conditions | Not covered by PMI. Initial acute phase may be covered; ongoing management is NHS |
| Cancer care | NHS cancer services; access to NICE-approved drugs. 62-day target currently met for ~68% of patients (Jan 2026) | Faster referral and diagnosis; access to some drugs not yet on NHS formulary (policy-dependent) |
Does private health insurance replace the NHS?
No. Private health insurance does not replace the NHS, and it is not designed to. You retain full entitlement to NHS care whether or not you hold a PMI policy. Emergency treatment, chronic illness management, and the vast majority of healthcare continues through the NHS. PMI adds a parallel route for new, acute conditions where you want faster access or greater choice – it does not remove, replace, or diminish your NHS entitlement. In practice, most people with PMI use the NHS for some things (emergencies, GP visits, long-term condition management) and private cover for others (planned investigations, elective surgery, specialist consultations). The two systems are complementary, not competing.
What is the difference between moratorium and full medical underwriting?
Underwriting is the process that determines which pre-existing conditions your policy will and will not cover. There are two main approaches in the UK. Moratorium underwriting automatically excludes any condition you have had in the past five years, with the exclusion capable of lifting after two claim-free years. Full medical underwriting (FMU) requires you to complete a detailed medical questionnaire at application, with each declared condition assessed individually upfront. The right choice depends on your health history, appetite for certainty, and whether you want clarity at the start or flexibility later.
| Factor | Moratorium Underwriting | Full Medical Underwriting (FMU) |
|---|---|---|
| Medical questionnaire required? | No – application is quick and simple | Yes – detailed health history required at application |
| How exclusions work | Any condition experienced in the past 5 years is automatically excluded at inception | Insurer assesses each declared condition individually and states explicitly what is and is not covered |
| Can exclusions be lifted? | Yes – if you go 2 consecutive years without symptoms, treatment, or advice for the excluded condition, it may be covered | Rarely – exclusions agreed at inception are usually permanent unless health significantly improves and insurer agrees to review |
| Certainty upfront | Lower – you may not know exactly what is excluded until a claim is investigated | Higher – you receive a list of covered and excluded conditions before you start paying |
| Suited to | People with minor or historical health issues who want a quick application and the chance to have exclusions lifted over time | People with a more complex health history who want to know exactly what they are covered for from day one |
| Cost difference | Broadly similar – the application simplicity is the advantage, not the cost | May cost slightly more or less depending on what the medical assessment reveals |
What cover levels are available and what do hospital networks mean?
PMI policies are not one-size-fits-all. Within a single insurer’s product range you will typically find several combinations of cover scope (what is included) and hospital access (where you can be treated). These two variables are independent of each other and together determine both your premium and your practical options when you need treatment.
| Policy Variable | Options | Impact on Premium |
|---|---|---|
| Cover scope | Basic (inpatient only), standard (inpatient + limited outpatient), comprehensive (full outpatient, diagnostics, mental health, therapies) | Basic cheapest; comprehensive most expensive. Comprehensive typically costs 40-60% more than basic |
| Hospital network | Standard list (limited hospitals), extended list (broader national choice), London list (includes high-cost London hospitals) | Broader network = higher premium. London list adds significant cost. Check your local private hospitals are included before choosing |
| Excess | £0 to £5,000+. Applied per condition, per year, or per claim depending on the policy | Higher excess reduces premium significantly. A £500 excess can save 15-25% vs a nil excess policy |
| Consultant access | Open referral (choose any consultant), guided/select (insurer helps you choose), named consultant (you specify) | Guided or select options save 15-20% vs fully open referral. Suitable for most people without an established specialist relationship |
| Six-week NHS wait option | Private treatment is only funded when NHS waiting time exceeds 6 weeks. If NHS can treat you within 6 weeks, you use the NHS | Can reduce premium by 20-30%. With current NHS waiting times, it triggers frequently in practice |
| No-claims discount (NCD) | Policies typically start with a significant NCD (often 65-70%). Claims reduce the discount, pushing renewal premiums up | NCD management is important – small claims may cost more in lost discount than the claim itself |
How much does private health insurance cost in the UK?
PMI premiums vary significantly by age, location, health, and cover chosen. A healthy non-smoker in their 30s can typically access basic inpatient cover for around £28-50 per month. The average single adult premium across all ages and cover levels is approximately £80-90 per month. Comprehensive cover for a family of four typically starts from around £200 per month.
| Profile | Basic Cover (approx./month) | Comprehensive Cover (approx./month) | Key Variable |
|---|---|---|---|
| Non-smoker, age 20-25 | ~£28-35 | ~£40-55 | Lowest risk age group; significant NCD available |
| Non-smoker, age 30-35 | ~£40-55 | ~£65-90 | Best time to start for value – low risk, long cover period |
| Non-smoker, age 45-50 | ~£70-95 | ~£110-160 | Pre-existing conditions more likely to create exclusions |
| Non-smoker, age 60-65 | ~£100-140 | ~£160-220 | Medical inflation and age loading make annual increases more significant |
| Couple, both age 40 | ~£130-180 | ~£200-280 | Joint policies or separate policies at same insurer can attract multi-person discount |
| Family (2 adults + 2 children) | ~£180-250 | ~£280-420 | Many insurers include children at no extra cost or at a reduced rate |
Premium ranges are approximate 2025 market indicators only. Your actual premium depends on your age, location, health history, chosen cover level, excess, and insurer. Always compare multiple quotes. See our private health insurance comparison page.
Who is private health insurance most suitable for?
PMI is not essential for everyone, and the NHS remains a strong option for most routine and emergency care. However, the case for PMI is strongest when a delay in diagnosis or treatment would have significant practical, financial, or personal consequences. The people who tend to get the most value are those for whom time – to work, to recover, to care for others – is at a premium.
You are most likely to benefit from PMI if you fall into one of these situations:
- →Self-employed workers and sole traders – an unexpected illness that takes you out of work for 6 months has immediate financial consequences. Speed of diagnosis and treatment directly protects income. Consider pairing with income protection insurance for comprehensive cover
- →Parents of young children – flexibility on timing and location of treatment is harder to manage when you are responsible for childcare around NHS appointment schedules
- →People with physically demanding jobs – a manual worker, tradesperson, or athlete who needs a knee or shoulder operation repaired quickly, not in 18 months
- →Anyone who values fast diagnostics – getting test results in days rather than weeks for peace of mind and faster clinical decision-making
- →People concerned about cancer care – faster referral and access to some drugs not yet available on the NHS formula is one of the most cited reasons for taking out PMI
- →Employers wanting to attract or retain staff – group PMI is one of the most valued employee benefits and is deductible as a business expense; employees pay income tax on the benefit in kind
Pro Tip: The Six-Week NHS Wait Option
Adding a six-week NHS wait option to your policy can reduce your premium by 20-30%, and with NHS waiting times running at current levels it triggers in a large proportion of cases anyway. Under this option, if the NHS cannot treat you within six weeks of referral you access private care through your policy. If the NHS can treat you within six weeks, you use the NHS. For people who want the safety net of private care without paying for it when the NHS is fast enough, this is often the best value structure – particularly for musculoskeletal conditions, where NHS waits are typically the longest.
How does PMI differ from life insurance and income protection?
PMI, life insurance, and income protection are three separate products protecting against three different events. They are not interchangeable and each covers a different risk. Many people hold more than one, and they work best as a combination rather than alternatives.
| Product | What Triggers a Payout | What It Pays | What It Protects Against |
|---|---|---|---|
| Private health insurance (PMI) | A new, acute medical condition requiring diagnosis or treatment | Private medical bills directly to the provider | NHS waiting times; getting the right treatment quickly |
| Life insurance | Death of the policyholder during the policy term | Tax-free lump sum to beneficiaries | Family financial security; mortgage; dependants |
| Income protection | Inability to work due to illness or injury | Regular monthly income (typically 50-70% of salary) | Bills, mortgage, and living costs if unable to work |
| Critical illness cover | Diagnosis of a specified critical illness (cancer, heart attack, stroke) | Lump sum paid to policyholder while alive | Home adaptation; debt clearance; loss of income during treatment |
The practical gap: PMI gets you treated quickly but does not pay your mortgage while you are off work recovering. Income protection does that. PMI does not pay your family anything if you die. Life insurance does that. None of these products can substitute for the others – they cover different events and work best in combination. For self-employed people in particular, the combination of PMI and income protection addresses both the treatment and the income risk simultaneously.
How do I use my private health insurance? Step-by-step
Using PMI is not the same as using the NHS. The process requires an authorisation step before treatment begins. Skipping this step – by booking private treatment without telling your insurer first – is one of the most common reasons claims are declined. The sequence below applies to most standard PMI claims in the UK.
Timeline of a PMI Claim
Symptom or concern arises
You notice a new symptom or health issue. See your NHS GP or use your policy’s private digital GP service for an initial assessment. This is not a claim step – it is a clinical triage step.
GP referral or pre-authorisation request
Your GP (NHS or private) issues a referral letter. Contact your insurer before booking any private appointment – most have a dedicated claims line or online portal. Provide the referral details and a description of the condition.
Insurer assesses and authorises
The insurer checks whether the condition appears to be new and acute (covered) or relates to a pre-existing exclusion (not covered). Most standard claims are pre-authorised within hours. You receive a pre-authorisation number and a list of approved consultants and hospitals within your network.
Specialist consultation
You book and attend a private specialist appointment, typically within days. Bring your referral letter and pre-authorisation number. The consultant assesses your condition and recommends a treatment plan. Diagnostic tests (MRI, CT, blood tests) may be ordered at this stage.
Diagnostics and further authorisation (if needed)
If tests or further treatment are recommended, the consultant or hospital usually contacts your insurer directly to confirm cover. For surgery or inpatient admission, a further authorisation step is typically required. Always confirm this is in place before proceeding.
Treatment
Treatment proceeds at the agreed private facility. In most cases the hospital invoices your insurer directly. You pay only your agreed excess (if any). Inpatient stays include a private room, meals, and nursing care. You will not typically receive or pay a large bill directly.
Claim settlement and follow-up
The insurer pays the provider directly and sends you an explanation of benefits showing what was covered and any excess applied. Follow-up appointments or physiotherapy may require a separate pre-authorisation. If a claim is disputed, you have the right to refer it to the Financial Ombudsman Service free of charge.
