As an FCA-authorised expert broker that has helped arrange over 800,000 policies, WeCovr knows the world of UK insurance. This guide clarifies the crucial differences between National Insurance and private medical insurance, helping you make informed decisions about your health and finances.
Understanding the difference between paying NI and having PMI
In the UK, we are fortunate to have a healthcare system funded by the state—the National Health Service (NHS). This system is primarily funded through National Insurance (NI) contributions. At the same time, a growing number of people are choosing to take out Private Medical Insurance (PMI).
But what's the real difference? In simple terms:
- National Insurance (NI) is a mandatory tax you pay. It funds the NHS, giving you access to healthcare that is free at the point of use. You don't get to choose your hospital, and you may face long waiting lists for non-urgent care.
- Private Medical Insurance (PMI) is an optional insurance policy you buy. It pays for you to be treated privately, giving you faster access to specialists and more choice over where and when you receive care for specific, short-term medical conditions.
Think of it like this: NI is your universal pass to the UK’s healthcare system, while PMI is like a fast-track ticket for certain journeys within it. They are not mutually exclusive; in fact, they work together.
This guide will break down everything you need to know about both systems, so you can understand their roles and decide if private health cover is the right choice for you.
What is National Insurance (NI)?
National Insurance is a fundamental tax on earnings and self-employed profits paid by employees, employers, and the self-employed in the UK. Your NI contributions are a legal requirement once you reach 16 and earn over a certain threshold.
The primary purpose of NI is to fund key state benefits, including:
- The State Pension: Building your entitlement for an income in retirement.
- The NHS: The largest portion of NI funding goes directly to our national healthcare service.
- Welfare Benefits: Such as Jobseeker's Allowance and Maternity Allowance.
Your NI contributions directly ensure the NHS can provide comprehensive medical care to every permanent resident in the UK, regardless of their ability to pay.
How Much National Insurance Do You Pay?
The amount of NI you pay depends on your employment status and how much you earn. For the 2024/2025 tax year, the rates are set by the government.
Here’s a simplified breakdown for employees (Class 1 contributions):
| Earnings Bracket | NI Rate (2024/2025) | What it Means for You |
|---|
| Up to £12,570 per year | 0% | You don't pay NI but still get the benefits. |
| £12,570 to £50,270 per year | 8% | This is the main rate you pay on your earnings. |
| Over £50,270 per year | 2% | You pay a lower rate on earnings above this threshold. |
The self-employed pay different classes of NI (Class 2 and Class 4) with their own rates. The key takeaway is that if you work in the UK, a portion of your income automatically goes towards funding the NHS.
What Does National Insurance Pay For? The Role of the NHS
Your NI contributions are the lifeblood of the National Health Service. The NHS was founded on the principle that good healthcare should be available to all, regardless of wealth. When you use the NHS, you are benefiting directly from the collective pool of NI payments.
Services Covered by the NHS
The scope of the NHS is vast. It covers almost every aspect of healthcare from cradle to grave, including:
- GP Visits: Consultations with your local doctor.
- Accident & Emergency (A&E): Urgent care for serious injuries and illnesses.
- Hospital Treatment: In-patient stays, surgery, and specialist care.
- Maternity Services: Antenatal care, childbirth, and postnatal support.
- Mental Health Services: Support from therapists, psychiatrists, and community teams.
- Prescriptions: In England, there's a fixed charge per item, but they are free in Scotland, Wales, and Northern Ireland.
The Challenge: NHS Waiting Times
While the NHS provides outstanding care, it is under immense pressure. One of the biggest challenges for patients today is waiting times for non-urgent procedures, known as elective care.
According to NHS England data, the waiting list for consultant-led elective care stood at around 7.5 million in early 2024. This means millions of people are waiting for procedures like hip replacements, cataract surgery, and hernia repairs. The target for treatment is 18 weeks from GP referral, but many patients wait significantly longer. This is the primary reason people explore private medical insurance.
What is Private Medical Insurance (PMI)?
Private Medical Insurance, often called private health cover, is an insurance policy that pays for the cost of private healthcare for acute conditions that arise after your policy begins.
An acute condition is a disease, illness, or injury that is likely to respond quickly to treatment and lead to a full recovery. Examples include joint pain requiring a replacement, hernias, or cataracts.
This is the most critical point to understand about PMI in the UK:
Standard UK private medical insurance does not cover pre-existing or chronic conditions.
- Pre-existing conditions: Any illness or injury you had before taking out the policy.
- Chronic conditions: Long-term illnesses that cannot be cured, only managed. Examples include diabetes, asthma, high blood pressure, and arthritis. The NHS will always manage these conditions.
PMI is designed to get you diagnosed and treated faster for new, curable health issues.
Key Differences: NI (NHS) vs. PMI at a Glance
This table summarises the core differences between the healthcare you get through your National Insurance contributions (the NHS) and the access provided by Private Medical Insurance.
| Feature | National Insurance (NHS) | Private Medical Insurance (PMI) |
|---|
| Funding | Mandatory tax on earnings. | Voluntary monthly/annual premiums. |
| Eligibility | All UK residents. | Policyholders only. |
| Cost at Point of Use | Free (except for prescriptions in England, dental etc.). | You may need to pay an excess. |
| Waiting Times | Can be long for non-urgent care. | Significantly shorter for eligible conditions. |
| Choice of Hospital | Limited to your local NHS trust. | Extensive choice from a national network of private hospitals. |
| Choice of Specialist | Assigned a consultant by the hospital. | You can often choose your specialist. |
| Hospital Facilities | Typically a shared ward. | Private, en-suite room is common. |
| Core Coverage | All conditions, including chronic, pre-existing & emergencies. | Acute conditions arising after the policy starts. |
| Emergencies (A&E) | The only option for emergency care. | Not covered. You must use the NHS A&E. |
| Mental Health | Available, but with long waiting lists for therapy. | Often included, providing faster access to support. |
How Do NI and PMI Work Together?
A common misconception is that PMI replaces the NHS. This is not true. Private medical insurance is designed to work alongside and complement the NHS, not substitute it.
Here’s a typical patient journey for someone with PMI:
- Initial Symptom: You feel unwell or have a health concern.
- NHS GP Visit: Your first port of call is always your NHS GP. They will assess you. This step is a requirement for nearly all PMI claims.
- NHS Referral: If your GP thinks you need to see a specialist, they will refer you. On the NHS, this would put you on a waiting list.
- Activate Your PMI: At this point, you contact your PMI provider. You give them your GP's referral details.
- Private Specialist & Diagnosis: Your insurer authorises a private consultation with a specialist, often within days. They will also cover the cost of any diagnostic tests like MRI or CT scans needed to identify the problem quickly.
- Private Treatment: If the diagnosis reveals an eligible acute condition requiring treatment (e.g., surgery), the insurer will cover the cost of the procedure in a private hospital.
- Return to NHS Care: After your private treatment, any ongoing follow-up or management of chronic issues returns to the NHS.
Crucially, all emergency care is handled by the NHS. If you have a heart attack or are in a serious accident, you go to A&E, just like everyone else.
What Does Private Medical Insurance UK Typically Cover?
While policies vary, a good private medical insurance plan usually includes:
- In-patient and day-patient treatment: Covers surgery, hospital stays, and procedures where you don't need to stay overnight.
- Out-patient diagnostics: Pays for tests like MRI scans, CT scans, and X-rays to find out what's wrong quickly.
- Out-patient consultations: Covers the cost of seeing a specialist.
- Comprehensive cancer cover: This is a major reason people buy PMI. It can include access to the latest cancer drugs and treatments, some of which may not be available on the NHS due to cost.
- Mental health support: Provides faster access to therapists, counsellors, and psychiatrists.
- Physiotherapy and complementary therapies: Helps with recovery after an injury or operation.
Many providers, like those WeCovr works with, offer modular policies. This allows you to build a plan that suits your needs and budget, adding or removing options like dental cover, travel insurance, or enhanced mental health support.
What is NOT Covered by Private Health Insurance?
Understanding the exclusions is just as important as knowing the benefits. Standard UK PMI policies will not cover:
- Pre-existing conditions: Any medical issue you sought advice or treatment for in the years before your policy started (typically the last 5 years).
- Chronic conditions: Long-term illnesses like diabetes, asthma, epilepsy, or hypertension that require ongoing management.
- Emergency services: You must always use the NHS A&E.
- Normal pregnancy and childbirth: Though complications can sometimes be covered.
- Cosmetic surgery: Unless it's reconstructive surgery needed after an accident or eligible procedure.
- Organ transplants.
- Drug and alcohol abuse treatment.
An expert PMI broker like WeCovr can help you navigate these exclusions and find a policy with the most suitable terms for your situation.
How Much Does Private Medical Insurance Cost?
The price of private health cover varies widely based on several factors:
- Age: Premiums increase as you get older because the risk of health issues rises.
- Location: Treatment in central London is more expensive, so policies covering London hospitals cost more.
- Level of Cover: A basic plan covering only in-patient care will be cheaper than a comprehensive plan with full out-patient, cancer, and mental health cover.
- Excess: This is the amount you agree to pay towards any claim. A higher excess (e.g., £500) will lower your monthly premium.
- Underwriting:
- Moratorium: The insurer automatically excludes conditions you've had in the last 5 years. It's quicker to set up.
- Full Medical Underwriting: You declare your full medical history. It takes longer but provides more certainty on what is and isn't covered from day one.
As a guide, a healthy 30-year-old might pay £30-£50 per month for a mid-range policy. A 55-year-old might pay £80-£120 per month for similar cover. An expert can provide precise quotes.
Is Private Medical Insurance Worth It in the UK?
This is a personal decision based on your priorities, finances, and attitude to risk.
Reasons to consider PMI:
- Peace of mind: Knowing you can bypass long NHS waiting lists for eligible conditions.
- Speed of access: Get diagnosed and treated faster, helping you return to work and life sooner.
- Choice and comfort: Choose your surgeon and hospital, and recover in a private room.
- Access to specialist drugs: Some policies provide access to new drugs not yet approved for NHS use.
Reasons it might not be for you:
- Cost: The monthly premiums can be a significant financial commitment.
- Exclusions: It doesn't cover everything, especially pre-existing and chronic conditions.
- You still need the NHS: It is not a replacement for the NHS, particularly for emergencies.
For many, the value lies in having a safety net. You hope you never need to use it, but if you do, it can make a stressful situation much more manageable.

Beyond Insurance: Proactive Steps for Better Health
Whether you have PMI or not, the best way to manage your health is to be proactive. Small lifestyle changes can significantly reduce your risk of developing many acute and chronic conditions.
- A Balanced Diet: Focus on whole foods, fruits, vegetables, lean proteins, and healthy fats. A balanced diet helps maintain a healthy weight and reduces the risk of heart disease, type 2 diabetes, and some cancers.
- Regular Physical Activity: The NHS recommends at least 150 minutes of moderate-intensity activity (like brisk walking or cycling) or 75 minutes of vigorous-intensity activity (like running) a week.
- Prioritise Sleep: Aim for 7-9 hours of quality sleep per night. Good sleep is essential for mental clarity, immune function, and physical recovery.
- Manage Stress: Chronic stress can impact your health. Practices like mindfulness, meditation, yoga, or simply spending time in nature can make a big difference.
Taking these steps helps you get the most out of life and reduces your reliance on any healthcare system, public or private.
Do I still need to pay National Insurance if I have private health insurance?
Yes, absolutely. Paying National Insurance is a legal requirement for all eligible earners and self-employed individuals in the UK. It funds the NHS, state pension, and other benefits. Private health insurance is an optional extra and does not exempt you from paying NI contributions. You will continue to rely on the NHS for emergency care, managing chronic conditions, and GP visits, all of which are funded by your NI.
Can I get private health insurance for a pre-existing condition?
Generally, no. Standard private medical insurance in the UK is designed to cover new, acute conditions that arise after your policy starts. Pre-existing conditions—any illness or injury you have had symptoms, medication, or advice for in the 5 years before joining—are typically excluded. Some policies may offer to cover them again after a set period (usually 2 years) without symptoms or treatment, but this is not guaranteed.
Does private health insurance cover dental and optical care?
Standard private medical insurance policies do not usually include routine dental or optical cover as a core benefit. However, most major insurers offer dental and optical protection as an optional add-on for an extra premium. This can help cover the costs of check-ups, treatments, and new glasses or contact lenses, so it's worth considering if you want comprehensive cover.
Is private medical insurance a taxable 'benefit in kind' if my employer pays for it?
Yes. If your employer pays the premiums for your private medical insurance, it is considered a 'benefit in kind' by HMRC. This means you will have to pay income tax on the value of the benefit (the cost of the premium). The amount will be added to your income for tax purposes and will be reflected on your P11D form at the end of the tax year.
