What does private medical insurance cover?
As the name suggests, private medical insurance covers the cost of private medical care. In many cases, private health insurance lets you pay to avoid the queue, accessing diagnosis, treatment, and recovery support more quickly than might be possible through the NHS.
Most private health insurance policies include inpatient treatment (i.e. stays in hospital) and day-patient care. They will often also cover outpatient consultations and diagnostic tests.
Typically, private health insurance will include:
Specialist consultations and diagnostic tests like MRIs or X-rays
Surgery and inpatient treatment
Hospital accommodation and nursing care
Physiotherapy and/or rehabilitation following surgery
Cancer care (depending on the level of cover you have)
As with most things, you get more if you pay more. Higher-tier health insurance policies may also include mental health support, complementary therapies, and access to private GP appointments.
What isn’t covered by medical insurance?
Ultimately, private health insurance providers are running businesses. They need to make a profit, which means they usually won’t cover conditions that have high-risk profiles. For example, policies are likely to exclude pre-existing conditions and emergency treatment. They might also exclude routine pregnancy care.
Common exclusions include:
Pre-existing medical conditions
Chronic illnesses such as diabetes or asthma
Dental treatments
Routine maternity care and childbirth
Cosmetic or elective (non-prescribed) procedures
Organ transplants
Substance misuse treatment
Experimental or unproven treatments
However, every insurer is different. Some insurers offer add-on options at extra cost for things like mental health and dental cover.
Why might I need private medical insurance?
Private health insurance isn’t a necessity in most cases, but it does provide convenience, flexibility, and reassurance. It’s especially beneficial for people who don’t have the flexibility to follow NHS schedules, and for those who prefer to avoid NHS waiting lists.
For example, self-employed individuals may appreciate the extra control over appointment times as it helps to avoid long absences from work. Private treatment can also give an extra level of privacy and comfort that many patients find appealing.
Private health insurance vs the NHS: a quick comparison
The NHS is one of the best healthcare providers in the world, and private medical insurers aren't trying to compete with it - they offer a different experience focused on speed, choice, and comfort. Here's how the two compare directly:
Attribute | Private medical insurance | NHS |
Waiting times | Typically much faster | Can be 18+ weeks for non-urgent treatment |
Consultant continuity | Usually the same consultant throughout | May see different consultants at different appointments |
Appointment scheduling | Chosen to suit you | Set by local hospital trust availability |
Room type | Usually private, ensuite | Often a shared ward |
Conditions covered | Acute conditions only | All conditions, including emergencies and pregnancy |
Cost | Monthly premiums | Free at the point of use |
How much does private medical insurance cost?
There is no ‘one-size-fits-all’ cost for private health insurance. What you pay depends on a variety of factors, including your age, your location, the insurer you pick, and the level of cover you want.
As a very rough guide, a typical family premium (two adults in their 40s and two children under 10) can vary from £700 to £1800 a year.
Younger, healthier people with basic cover will typically pay at the lower end of this range, while older people and people who choose more comprehensive policies will pay more.
You can also expect costs to be higher if you add extras like mental health support to your policy.
What affects the cost of medical insurance
Let’s go into a bit more detail about the factors that influence the cost of your premium:
Geography
Healthcare costs vary considerably by region. People living in London and the South East, for example, can expect to pay more for a health insurance policy than people in other parts of the UK.
Age
Age is one of the most significant risk (and therefore cost) factors for private health insurers. Older people are more likely to make medical insurance claims. As such, premiums increase the older you get.
If you take out medical insurance over the age of 50, you could end up with steep premium prices. So, if you can, it’s often better to sign up young and build up loyalty discounts, but this is something to verify with the insurance provider.
Level of cover
Comprehensive policies that include outpatient care, private GP access, international cover, etc., offer more and, therefore, cost more. Basic plans that only cover inpatient and day-patient treatment are cheaper.
Excess
The excess is the amount you pay towards a claim before your insurer covers the rest. A higher excess means less risk for your insurer, which usually translates into a lower monthly premium. However, it means that you will end up paying more out-of-pocket if you do make a claim.
6-week NHS wait option
Some policies include a six-week option: if the NHS can provide your treatment within six weeks, you use the NHS instead of going private. This may reduce policy premiums and suit those who don’t mind waiting a bit.
Lifestyle factors
Your lifestyle and overall health can affect pricing. If you smoke, drink, and have a high BMI, you are at a higher risk of making a claim and can expect to pay more. People with healthier lifestyles benefit from lower premiums. Some insurers even offer wellness incentives like discounted gym memberships.
How can you keep costs down?
There are plenty of ways to reduce the cost of private medical insurance without sacrificing quality of cover. Here are some of the most reliable:
Insurers have a variety of pricing structures, coverage options, and perks. Comparing multiple providers makes sure that you get the best value for your needs.
Opting for a higher excess can significantly lower your monthly premiums. But do make sure the excess is affordable for you in case you need to make a claim.
Many insurers allow you to choose from a network of approved hospitals. Larger networks can be more expensive, but opting for smaller networks can keep costs affordable.
If you are covering multiple people, a family policy may work out cheaper than individual plans. Some providers also offer child cover at no extra cost.
Your healthcare needs are likely to change over time. Regularly reviewing your policy makes sure that you are not paying for cover you don’t need and gives you insight into new discounts or policy options that could benefit you.
Full medical vs moratorium underwriting
When you take out a new PMI policy, insurers assess pre-existing conditions in one of two ways:
Full medical underwriting - you're asked detailed questions about your medical history upfront. The insurer tells you clearly which conditions are covered and which are excluded from day one.
Moratorium underwriting - there's no upfront medical questionnaire. Instead, any condition you've had treatment, medication or advice for in the last five years in most cases is automatically excluded. If you then go a set period (often two years) without needing treatment for that condition, it can become covered.
If you're switching from an existing policy, ask about continuation of underwriting and many insurers will carry across the same terms you already have, rather than reassessing you from scratch. Our guide on changing your private medical insurance provider covers this in more detail.
When PMI might not be worth it
PMI isn't the right choice for everyone. It may not be worth taking out if:
You're happy to rely on the NHS for most or all of your care
You already have cover through an employer or workplace benefits scheme
You have debt to clear or no savings buffer as those are generally a higher priority than a PMI premium
You only need cover for a condition that's excluded anyway, such as a pre-existing or chronic condition
Does PMI let you skip NHS queues?
PMI doesn’t entirely allow you to skip NHS queues. Having PMI gives you faster access to private treatment, but it doesn't give you priority within the NHS itself. If you ever need NHS care, you're subject to the same waiting times as anyone else. The speed benefit only applies to the private treatment your policy covers
What are the alternatives to private medical insurance?
PMI is not the only way to access private care. There are alternatives, which can offer greater flexibility and (sometimes) lower overall cost:
You don’t necessarily need a private insurance contract to access private healthcare. If it's affordable for you, you can pay for private medical treatments out of pocket. Most private hospitals have transparent price lists for common procedures. So if you’re looking for something specific that you can’t get on the NHS, it may be worth looking into self-pay private treatment rather than taking out insurance.
You can use health care cash plans alongside your NHS treatments. For example, things like dental and optical treatments are hard to access on the NHS, but with a health cash plan, you can get these done privately and be reimbursed by your insurer. Health cash plans don’t give full private cover, but they can help manage routine expenses.
These types of plans don’t pay for medical treatment, but they do offer financial protection if you have health issues that affect your ability to earn. Critical illness protection will pay out a lump sum if you are diagnosed with something serious. Income protection provides regular payments if you can’t work.
Find peace of mind with private medical cover
So, is private medical insurance worth it? The answer depends on your priorities, your health needs, and your financial situation.
For some, private health insurance gives peace of mind. It's comforting to know that you have faster access to treatment, and the comfort of private facilities should you need them. This peace of mind is well worth the costs for some.
Others, especially those in good health or with tight budgets, may find that the NHS provides all the care they need with no need to pay a monthly premium.
Ultimately, private medical insurance can be a valuable investment if you want control, speed, and comfort in your healthcare journey. The best approach is to assess your needs, compare providers, and balance cost against peace of mind.
