Compare NHS and private health insurance to find the right option

Choosing between relying solely on the NHS or adding private health insurance is one of the most common healthcare decisions UK residents face. Both options have genuine strengths, and the right choice depends entirely on your circumstances, priorities, and budget.

The NHS remains a cornerstone of UK healthcare, providing free treatment funded through taxation to all UK residents. Private health insurance offers faster access to non-emergency treatments and more choice over consultants and hospitals. Understanding how these two options compare across cost, waiting times, coverage, and comfort helps you make an informed decision. The table below provides a side-by-side comparison of the most important factors to consider.

Quick verdict: The NHS provides comprehensive coverage for serious conditions, emergencies, and ongoing chronic care at no direct cost. Private health insurance excels at reducing waiting times for planned treatments and offering more choice and comfort. Many people use both, keeping their NHS access while using private insurance to skip queues for non-urgent issues.

The National Health Service has provided universal healthcare to UK residents since 1948. Funded through general taxation and National Insurance contributions, treatment is free at the point of use for anyone ordinarily resident in the UK.

What the NHS covers

• Primary care: GP appointments for diagnosing conditions, managing ongoing health issues, and referrals to specialists. While appointments are free, getting one can sometimes take several weeks depending on your area.
• Hospital treatment: All medically necessary inpatient and outpatient care, including surgery, cancer treatment, cardiac care, and emergency services. Drugs administered in hospital are free.
• Emergency care: A&E departments operate 24/7 and treat anyone regardless of residency status. Emergency ambulance services are also free.
• Maternity care: Full antenatal, birth, and postnatal care is provided free of charge, including midwife appointments, scans, and hospital births.
• Mental health services: Talking therapies, psychiatric care, and community mental health support are available, though waiting times can be significant.
• Specialist services: Cancer care, heart surgery, organ transplants, and other complex treatments are fully covered, often in world-class NHS facilities.

What the NHS charges for

Some services require payment:

• Prescriptions: £9.90 per item in England (free in Scotland, Wales, and Northern Ireland). A prepayment certificate costs £31.25 for 3 months or £111.60 for 12 months.
• Dental treatment: Band 1 (check-up) costs £26.80, Band 2 (fillings, extractions) costs £73.50, and Band 3 (crowns, dentures, bridges) costs £319.10.
• Eye tests and glasses: Most adults pay for eye tests (typically £20-£30) and glasses. Free tests are available for those over 60, under 16, or receiving certain benefits.
• Some treatments: Certain procedures are not routinely available, including most cosmetic surgery, some fertility treatments (varies by area), and certain newer drugs not yet approved by NICE.

Current NHS challenges

The NHS has faced significant pressure in recent years. According to NHS England data, the waiting list for hospital treatment stood at around 7.4 million in August 2025. The median waiting time was 12.9 weeks, a significant increase from the pre-COVID median of 7.7 weeks in November 2019.

In A&E, 73.8% of people were admitted, transferred, or discharged within 4 hours in December 2025. For cancer care, 76.5% of patients were told they have cancer within four weeks of an urgent referral in November 2025, above the 75% operational target.

These pressures are a key reason many people consider private health insurance, particularly for non-urgent treatments where waiting can significantly impact quality of life.

Private health insurance (also called private medical insurance or PMI) pays for private healthcare treatment when you become unwell. It is designed to work alongside the NHS, not replace it.

What private health insurance typically covers

• Inpatient treatment: Hospital stays, surgery, nursing care, and accommodation in a private hospital or NHS private patient unit.
• Outpatient treatment: Consultations with specialists, diagnostic tests (MRI scans, CT scans, blood tests), and follow-up appointments. Outpatient cover is often not included in basic policies.
• Cancer treatment: Diagnosis, surgery, chemotherapy, radiotherapy, and related care. This is typically included in comprehensive policies and is often a key reason people buy cover.
• Mental health support: Many policies now include telephone counselling and some face-to-face therapy sessions. Coverage varies significantly between providers.
• Physiotherapy: Access to physio sessions, often with shorter waits than NHS physiotherapy services.
• Private rooms: Most private hospital stays include a private room with en-suite facilities.

What private health insurance does not cover

• Emergency treatment: Private hospitals generally do not have A&E departments or intensive care units capable of handling emergencies.
• Pre-existing conditions: Conditions present before taking out the policy are usually excluded. Some policies use moratorium underwriting where pre-existing conditions may be covered after a symptom-free period of 2-5 years.
• Chronic conditions: Ongoing conditions like diabetes, asthma, or arthritis that require long-term management are typically not covered. Initial diagnosis might be covered, but ongoing care will not be.
• Pregnancy and childbirth: Routine maternity care is almost never covered. Some policies offer limited complications cover.
• GP appointments: You will still use your NHS GP for most routine appointments. Some comprehensive policies include private GP access as an add-on.
• Cosmetic procedures: Elective cosmetic surgery is not covered unless it is reconstructive surgery following illness or injury.

How claims work

1. See your GP: Even with private insurance, you usually need a GP referral first.
2. Contact your insurer: Before booking appointments, call your insurer to confirm coverage and get pre-authorisation.
3. Choose your specialist: Once authorised, select a consultant from your insurer's approved list.
4. Receive treatment: Your insurer pays the hospital and consultant directly. You pay any excess you have agreed to.
5. Follow-up care: Post-treatment consultations and physiotherapy are usually covered, subject to your policy terms.

NHS costs

The NHS is funded through general taxation and National Insurance. While free at the point of use, you contribute through National Insurance (employees pay 12% on earnings between £12,570 and £50,270, plus 2% above that) and general taxation. NHS expenditure was £242 billion in 2024/25. The only direct costs for most people are prescriptions (£9.90 per item in England), dental charges, and optical care.

Private health insurance costs

Private health insurance premiums vary based on several factors:

• Age: The biggest factor. A healthy 30-year-old might pay £40-£60 per month, while a 60-year-old could pay £150-£250 per month for equivalent cover.
• Level of cover: Basic inpatient-only policies are cheapest. Adding outpatient cover, mental health support, and other benefits increases costs.
• Excess: Choosing a higher excess (the amount you pay per claim) reduces your premium. Common levels are £0, £100, £250, £500, and £1,000.
• Location: Premiums are typically higher in London and the South East due to higher private healthcare costs.
• Hospital choice: Limiting your choice to a smaller network of hospitals can reduce premiums by 10-20%.

According to industry research, the average monthly premium for a comprehensive policy in 2025 is estimated at £60 to £95 per month for a healthy individual in their 30s or 40s.

Annual cost example: A 45-year-old paying £85 per month would spend £1,020 per year. Over 20 years, that totals £20,400 in premiums, not accounting for annual increases.

Ways to reduce private health insurance costs

• Choose a higher excess: Increasing your excess from £0 to £500 can reduce premiums by 20-30%. Only do this if you could comfortably pay the excess when needed.
• Six-week NHS option: Some policies only cover you privately if NHS waiting times exceed six weeks, significantly reducing premiums.
• Limited hospital networks: Accepting a smaller choice of hospitals (often excluding central London) can save 10-20%.
• Company schemes: Employer-provided private medical insurance is usually much cheaper due to group rates, and the underwriting is often more favourable.
• Pay annually: Many insurers offer a 5-10% discount for paying the full premium upfront rather than monthly.
• Review cover levels: A basic inpatient-only policy might be sufficient if you are mainly concerned about avoiding long waits for surgery.

Waiting times are often the decisive factor for people considering private health insurance.

NHS waiting times

• Consultant referrals: The median waiting time for patients to start treatment was 12.9 weeks. For some specialties like orthopaedics, waits can be significantly longer.
• A&E: 74% of people attending A&E were admitted, transferred, or discharged within 4 hours, meaning around 26% waited longer than the target.
• Cancer diagnosis: 76.5% of patients were told whether they have cancer within 28 days of an urgent referral, meeting the 75% target.
• Diagnostic tests: Waits for MRI scans, CT scans, and other diagnostics can add weeks to overall waiting time.

Private healthcare waiting times

• Consultant appointments: Typically available within days to 2 weeks, often with evening and weekend options.
• Diagnostic tests: MRI scans, CT scans, and blood tests usually completed within 1-2 weeks.
• Surgery: Non-emergency procedures can often be scheduled within 2-4 weeks of diagnosis.
• Follow-up care: No queue for post-treatment consultations and physiotherapy.

When waiting times matter most

Private insurance offers the biggest advantage for:

• Joint replacements: NHS waits can extend to 12-18 months in some areas. Private treatment is typically available within weeks.
• Cataract surgery: Another area where NHS waits can be substantial, but private surgery is readily available.
• Diagnostic investigations: Getting answers faster can reduce anxiety and potentially catch conditions earlier.
• Physiotherapy: The NHS often limits sessions, while private cover typically offers more comprehensive rehabilitation.
• Mental health support: NHS talking therapy services have long waits in many areas. Private policies with mental health cover can provide faster access.

The NHS is the better option in several common situations.

For emergencies

If you have a heart attack, stroke, serious injury, or any life-threatening condition, NHS emergency services are where you need to be. Private hospitals do not have A&E departments or intensive care facilities to handle emergencies. Even with comprehensive private insurance, you will use NHS A&E for any urgent situation.

For chronic conditions

Conditions requiring lifelong management, such as diabetes, epilepsy, multiple sclerosis, rheumatoid arthritis, or heart disease, are fully covered by the NHS but typically excluded from private policies. The NHS will manage your condition for your entire life without additional cost.

For maternity care

The NHS provides comprehensive maternity care from your first antenatal appointment through to postnatal checks. Private maternity care exists but is extremely expensive (£10,000-£20,000+ for birth alone) and rarely covered by insurance.

For complex specialist care

For conditions like advanced cancer, organ failure requiring transplant, or complex cardiac problems, NHS specialist centres often provide world-class care. Private hospitals may not have the facilities, expertise, or equipment for the most complex cases.

If budget is a primary concern

If money is tight, the NHS provides good care at no direct cost. Private insurance premiums of £60-£200 per month could instead go toward other financial priorities, savings, or paying off debt.

For children

Children are prioritised by the NHS and typically face shorter waiting times than adults. Many private hospitals do not treat very young children, and paediatric specialists are often NHS-based. Adding children to a private policy adds cost with often limited benefit.

Private health insurance makes more sense in these situations.

If waiting times significantly affect you

If you are experiencing a condition that impacts your daily life, work, or mental health, waiting months for treatment can be genuinely harmful. Private insurance lets you access treatment while you can still work, exercise, and live normally. For example, facing an 8-month NHS wait for a hip replacement, private insurance could provide surgery within 3 weeks, allowing a return to work within 6 weeks.

If you value choice and control

With private insurance, you choose your consultant, your hospital, and often your appointment times. You can research specialists, read reviews, and select someone who specialises in your specific condition. This level of control matters to many people.

If you are self-employed or a key earner

If being unable to work has serious financial consequences, the faster treatment access that private insurance provides can be genuinely valuable. Many self-employed people find peace of mind in knowing they will not face long waits if something goes wrong.

If you want better hospital facilities

Private hospitals typically offer private rooms, better food, more flexible visiting hours, and a quieter environment. If comfort and privacy during treatment matter to you, this is a genuine benefit.

If your employer offers it

If your employer provides private medical insurance as a benefit, it is usually worth taking. You will pay some tax on the benefit (it is classed as a benefit in kind), but you are still getting cover much cheaper than you would pay individually, and employer schemes often have better terms.

If you have specific treatment concerns

If your family has a history of conditions where early diagnosis and treatment improve outcomes, such as certain cancers or heart conditions, the faster access that private insurance provides might be particularly valuable.

Most people with private health insurance do not abandon the NHS. Instead, they use both systems strategically.

What to use the NHS for

Even with private insurance, you will typically use the NHS for:

• GP appointments: Your NHS GP remains your first point of contact and provides referrals for both NHS and private care
• Emergencies: All emergency and urgent care goes through NHS A&E
• Chronic condition management: Ongoing care for diabetes, heart disease, asthma, and similar conditions
• Prescriptions: Your NHS GP can prescribe medications whether your treatment was NHS or private
• Maternity care: Pregnancy and childbirth remain NHS services
• Vaccinations and screening: NHS vaccination programmes, cancer screening, and health checks

What to use private insurance for

• Non-urgent surgeries: Joint replacements, hernia repairs, gallbladder removal where NHS waits are long
• Diagnostic investigations: Getting MRI scans, CT scans, or other tests done quickly
• Specialist consultations: Seeing a specific consultant of your choice
• Physiotherapy: Accessing more sessions than the NHS typically provides
• Some mental health support: Counselling and therapy where your policy allows

Important: you cannot use both simultaneously

You cannot have the same condition treated by both the NHS and privately at the same time. If you start treatment privately, you continue privately. If you want NHS care, you join the NHS waiting list like everyone else. However, you can choose which route to take for each new condition. A broken leg might go through NHS A&E, while back pain might be investigated privately.
