As an FCA-authorised broker that has helped arrange over 900,000 policies, WeCovr knows that understanding private medical insurance in the UK can feel complex. This guide demystifies how your premium is calculated, empowering you to make informed choices about your health cover.
A private medical insurance (PMI) premium is the regular amount—usually paid monthly or annually—you pay to an insurer in exchange for health cover. But how do insurers arrive at that specific figure? It’s not arbitrary. It's the result of a detailed risk calculation.
Insurers are experts in assessing the likelihood of a person making a claim. They analyse a combination of personal details, lifestyle choices, and the specific level of cover you select. The higher the perceived risk of you needing private medical treatment, the higher your premium will be.
Think of it as a balancing act. You are balancing the level of cover you want against a premium that fits your budget. In this guide, we'll break down every single factor, from the most obvious to the less well-known, so you can see exactly what drives the cost of your policy.
These are the fundamental details about you that form the bedrock of your premium calculation. While you can't change your age or (easily) your location, understanding their impact is crucial.
Age is, without doubt, the single biggest determinant of your PMI premium. From an insurer's perspective, the statistical reality is that as we get older, we are more likely to experience health issues and require medical treatment.
Insurers use vast datasets called "actuarial tables" to predict the average cost of claims for each age. This is why your premium will increase each year on renewal, even if you haven't made a claim. This is due to a combination of your "age-rated" increase and medical inflation.
Illustrative Monthly Premiums by Age
The table below shows example costs for a non-smoking individual with a mid-range policy and a £250 excess. Actual quotes will vary significantly.
| Age Bracket | Illustrative Monthly Premium | Common Health Concerns at This Age |
|---|---|---|
| 30-39 | £45 | Musculoskeletal issues, early diagnostics |
| 40-49 | £65 | Joint pain, heart health checks, digestive issues |
| 50-59 | £90 | Cancer screenings, joint replacements, cardiovascular care |
| 60-69 | £150+ | Cataracts, complex surgeries, ongoing monitoring |
Where you live in the UK has a direct and significant impact on your premium. This isn't about local health risks; it's purely about the cost of private medical care in your area.
Private hospitals in major cities, particularly Central London, have much higher running costs—from consultant fees and nursing staff wages to rent and state-of-the-art equipment. These costs are passed on to insurers, who in turn factor them into the premiums for customers living in those postcodes.
You can control this factor by choosing a policy with a specific "hospital list," which we'll cover later.
Insurers take a very clear stance on smoking: it is one of the biggest voluntary health risks a person can take. Data consistently shows that smokers are far more likely to suffer from a range of serious, expensive-to-treat conditions, including:
Because of this heightened risk, insurers apply a "loading" to the premiums of smokers, which can be anywhere from 30% to 50% higher than for a non-smoker. Most insurers define a "smoker" as anyone who has used any nicotine products, including cigarettes, cigars, pipes, and often vapes, within the last 12 months.
Quitting smoking is not only the best thing you can do for your health but also one of the most effective ways to reduce your private health cover costs over time.
This is where you have the most control. The choices you make when building your policy will directly influence your monthly premium. Working with an expert PMI broker like WeCovr can help you navigate these options to find the perfect balance between comprehensive cover and affordability.
Private medical insurance UK policies are typically structured in tiers.
| Level of Cover | What's Typically Included | Impact on Premium |
|---|---|---|
| Basic | In-patient & Day-patient treatment only | Lowest Cost |
| Mid-Range | Core cover + limited out-patient diagnostics/consultations | Moderate Cost |
| Comprehensive | Core cover + full out-patient + extras (mental health, therapies) | Highest Cost |
An 'excess' is a fixed amount you agree to pay towards the cost of a claim. For example, if you have a £250 excess and your private treatment costs £3,000, you would pay the first £250, and the insurer would pay the remaining £2,750.
The relationship is simple: the higher your excess, the lower your monthly premium.
By agreeing to a higher excess, you are taking on a greater share of the initial financial risk, which reduces the insurer's potential payout. Most insurers offer a range of excess options, typically from £0 up to £1,000 or more. Choosing an excess you are comfortable paying is a powerful tool for managing your premium.
Illustrative Impact of Excess on a £70 Monthly Premium
| Excess Level | Adjusted Monthly Premium (Illustrative) | Annual Saving vs. £0 Excess |
|---|---|---|
| £0 | £70 | £0 |
| £100 | £65 | £60 |
| £250 | £58 | £144 |
| £500 | £50 | £240 |
| £1,000 | £42 | £336 |
To manage the impact of location costs, insurers create 'hospital lists' or 'networks'. By selecting a more restricted list, you can significantly reduce your premium.
When choosing, be realistic. If you live in Edinburgh, do you really need access to a Central London hospital? For most people, a national list provides more than enough choice.
This is one of the most popular cost-saving features on a PMI policy. If you add the six-week option, it means that for in-patient treatment, you must first check the NHS waiting list.
According to the latest NHS England data, the median waiting time for consultant-led elective care was 14.5 weeks in mid-2024, with hundreds of thousands waiting over a year. Given these lengthy waits, the six-week option often provides a significant premium discount (up to 20-30%) with a relatively low chance of you actually having to rely on the NHS.
This is a critical part of the process, and one that causes much confusion. First and foremost, it is essential to understand this point:
Standard UK private medical insurance is designed to cover acute conditions that arise after you take out the policy. It does not cover chronic or pre-existing conditions.
There are two main ways an insurer will assess your medical history to apply these rules.
This is the most common and straightforward method.
This method provides more certainty from the outset.
The choice between these two can be complex. An adviser at WeCovr can explain the pros and cons based on your personal health history to help you decide which underwriting method is best for you.
Beyond the core personal and policy choices, a few other elements can affect your premium, both at the start and over the life of your policy.
Similar to car insurance, most PMI policies feature a No Claims Discount system. It works like a ladder:
This system rewards customers who stay healthy and do not use their insurance, while ensuring that those who do claim contribute more towards the overall risk pool.
In a competitive market, insurers add a host of benefits to their policies to make them more attractive. While many are included as standard, more comprehensive packages with richer benefits will naturally cost more. These can include:
When you purchase a policy through WeCovr, you not only get expert advice but also complimentary access to our proprietary AI-powered calorie and nutrition tracker, CalorieHero. Furthermore, our clients often receive discounts on other types of insurance, such as life or home insurance, as a thank you for their custom.
Let's look at three fictional profiles to see how all these factors combine to create a final premium. These are for illustrative purposes only.
| Profile Details | Sarah (32, Manchester) | David (55, London) | The Miller Family (Bristol) |
|---|---|---|---|
| Age(s) | 32 | 55 | 40, 38, 8, 6 |
| Smoker? | No | Yes | No |
| Location | Manchester | Central London | Bristol |
| Cover Level | Mid-Range | Comprehensive | Mid-Range |
| Excess | £250 | £100 | £500 |
| Hospital List | National | Premium London | National |
| Special Options | None | None | 6-Week Option |
| Illustrative Premium | ~£55 / month | ~£250 / month | ~£140 / month (for all 4) |
As you can see, David's combination of older age, being a smoker, living in London, and wanting the highest level of cover results in a premium that is dramatically higher than Sarah's. The Miller family effectively manages their costs by choosing a higher excess and the six-week option.
Securing the right private health cover isn't about finding the absolute cheapest policy; it's about finding the best value—the policy that provides the right level of protection for your needs at a price you can afford.
