Deciding on the right private medical insurance in the UK can feel complex, especially for couples. As an FCA-authorised expert broker that has helped arrange over 800,000 policies of various kinds, WeCovr understands the nuances. This guide demystifies the costs of joint versus single PMI policies.
Which policy type works out cheaper in practice?
In practice, two single private health insurance policies are often cheaper than one joint policy for a couple. While insurers may offer a small discount (typically around 5%) for a joint plan, the savings are often eliminated if the two individuals have different health needs or a significant age gap.
The cheapest overall price is frequently found by purchasing two separate policies from different insurers, each tailored to the specific individual's age and requirements.
For example, a 30-year-old might find the best value with Bupa, while their 45-year-old partner might secure a more competitive premium with Aviva. The combined cost of these two single policies can easily be less than a joint policy from either Bupa or Aviva alone.
The only way to know for sure is to compare quotes for both scenarios across the entire market, a service provided at no cost by an expert broker like WeCovr.
Understanding Single vs. Joint Private Health Insurance
Before diving into the costs, let's clarify the terminology. The structure of your policy is the first big decision you'll make.
What is a Single Policy?
As the name suggests, a single private medical insurance (PMI) policy covers just one person. The premium, benefits, and claims history are all tied exclusively to that individual.
What is a Joint Policy?
A joint policy, often called a couple's policy, covers two people on a single plan. This is typically for married couples, those in a civil partnership, or partners who live together. You share one policy document, one renewal date, and make one combined payment.
What about Family Policies?
For completeness, a family policy extends this concept to cover one or two adults plus one or more of their children under a single plan. This is usually the most cost-effective way to insure a whole family until the children reach a certain age (often 21, or 25 if in full-time education).
Here’s a simple breakdown:
| Feature | Single Policy | Joint Policy |
|---|
| People Covered | One individual | Two partners living together |
| Premium | Based on one person's risk profile | A combined premium, based on both |
| Administration | Separate documents & payments | One policy document, one payment |
| No Claims Discount | Affects only the individual | A claim by one can affect both |
The Core Question: Is a Joint Policy Cheaper Than Two Singles?
This is the central issue for most couples, and the answer is not as straightforward as you might think. Insurers love simplicity, and having two people on one policy reduces their administrative overheads. To encourage this, most will offer a small "multi-person" discount.
The "Joint Policy Discount": Myth vs. Reality
The Reality: Most UK private health insurance providers will apply a small discount, often around 5%, when you add a second person to a policy, creating a joint plan.
The Myth: That this 5% discount automatically makes the joint policy the cheapest option.
The UK's PMI market is incredibly competitive. The premium an insurer quotes is highly sensitive to age, location, and desired cover level. The insurer that is cheapest for a 35-year-old in Manchester is rarely the cheapest for a 50-year-old in London.
This is where the strategy of buying two single policies comes into play.
Illustrative Cost Scenarios
To make this clear, let's look at some real-world examples. The prices below are illustrative monthly premiums for a comprehensive policy with a £250 excess, based on 2025 market averages.
Scenario 1: Couple with Similar Ages & Needs
- Partner A: 35-year-old, non-smoker, living in Bristol.
- Partner B: 37-year-old, non-smoker, living in Bristol.
| Policy Option | Insurer | Partner A Premium | Partner B Premium | Total Monthly Cost |
|---|
| Two Single Policies | Vitality | £55 | £58 | £113 |
| Joint Policy | Vitality | - | - | £107 (with 5% discount) |
| Two Single Policies | AXA Health | £57 | £60 | £117 |
| Joint Policy | AXA Health | - | - | £111 (with 5% discount) |
Conclusion: In this case, where the couple has a very similar risk profile, a joint policy from a single insurer is slightly cheaper. The 5% discount provides a clear, though modest, saving.
Scenario 2: Couple with a Significant Age Gap & Different Needs
- Partner A: 32-year-old, non-smoker, needs basic cover, lives in Leeds.
- Partner B: 48-year-old, non-smoker, wants comprehensive cover with mental health, lives in Leeds.
Now, let's see how comparing the market for single policies can beat a joint plan.
| Policy Option | Insurer(s) | Details | Total Monthly Cost |
|---|
| Joint Policy Option | Bupa | One comprehensive policy covering both partners. | £165 |
| Joint Policy Option | Aviva | One comprehensive policy covering both partners. | £172 |
| Strategic Singles | WPA + The Exeter | Partner A: Basic single policy with WPA (£42/month). Partner B: Comp single policy with The Exeter (£115/month). | £157 |
Conclusion: In this more realistic scenario, the cheapest option is to use a "mix and match" approach. By placing each partner with the insurer that offers the best value for their specific age and needs, the couple saves £8 per month (£96 per year) compared to the cheapest joint policy option. This highlights the power of a whole-of-market comparison.
Factors That Determine Your Private Health Insurance Premium
Understanding why premiums vary is key to finding the best value. Insurers are essentially calculating risk. Here are the main dials they turn:
- Age: This is the single biggest factor. The likelihood of needing medical treatment increases with age, so premiums rise accordingly. The increase becomes particularly steep after the age of 50.
- Location: Your postcode matters. Treatment at a central London hospital like The Cromwell can cost significantly more than at a private hospital in a smaller town. Insurers price this risk into your premium.
- Level of Cover: You can customise your policy to fit your budget.
- Basic: Covers treatment only when you are admitted to a hospital bed (in-patient).
- Comprehensive: Covers in-patient care plus specialist consultations, diagnostic tests, and scans on an out-patient basis. This is the most popular choice.
- Optional Extras: You can add cover for mental health, dental and optical care, and therapies (like physiotherapy), each adding to the cost.
- Excess: This is the amount you agree to pay towards a claim in any policy year. A higher excess (e.g., £500 or £1,000) will significantly lower your monthly premium. A £0 excess is the most expensive option.
- Hospital List: Insurers offer different tiers of hospitals. A policy that includes premium central London hospitals will cost more than one with a more restricted nationwide list.
- Underwriting Type: This determines how the insurer treats your past medical conditions.
- No Claims Discount (NCD): Similar to car insurance, your premium will be discounted for every year you don't make a claim, often up to a maximum of 65-75%.
- Lifestyle: Smokers or vapers will pay substantially more—often 30-50% extra—than non-smokers due to the associated health risks.
The Critical Exclusion: Pre-existing and Chronic Conditions
This is the most important concept to understand about UK private health insurance. It is a fundamental principle that often causes confusion.
Standard UK PMI is designed to cover acute conditions that arise after you take out your policy.
- Acute Condition: A disease, illness, or injury that is likely to respond quickly to treatment and lead to a full recovery. Examples include joint replacements, cataract surgery, hernia repair, and cancer treatment.
- Chronic Condition: A condition that has no known cure and is managed with ongoing monitoring or treatment. Chronic conditions are not covered by private medical insurance. Examples include diabetes, asthma, hypertension, and Crohn's disease. PMI may cover the initial diagnosis of a chronic condition, but once diagnosed, its long-term management reverts to the NHS.
- Pre-existing Condition: Any illness, disease, or injury for which you have experienced symptoms, received medication, advice, or treatment in the five years before your policy start date. These are typically excluded from cover for an initial period (usually 24 months) on a moratorium policy.
It is vital to be honest about your medical history. Failing to declare conditions can lead to your policy being cancelled and claims being denied.
The Strategic Advantage of Using a Broker Like WeCovr
The complexity of joint vs. single policies, combined with the dozens of variables affecting price, is precisely why using an independent PMI broker is so effective.
- Whole-of-Market Comparison: An individual might get a quote from Aviva and Bupa. A broker like WeCovr compares policies from across the entire UK market. We can instantly see if a joint policy with Vitality is cheaper than two separate single policies with AXA and The Exeter.
- Tailored, Unbiased Advice: We work for you, not the insurer. Our job is to find the best-value cover for your specific circumstances. We can identify if your needs and your partner's are different enough to warrant two separate policies. Our advice is based on a deep understanding of the market, not allegiance to one brand.
- No Extra Cost to You: Our service is free. We receive a commission from the insurer you choose, which is already built into the premium. You pay the same price (or often less) as going direct, but you benefit from expert, impartial guidance.
- High Customer Satisfaction: Our focus on clear, honest advice has earned us high satisfaction ratings from our clients. We are authorised and regulated by the Financial Conduct Authority (FCA), giving you peace of mind.
Beyond Cost: Other Considerations for Joint vs. Single Policies
While price is a major driver, it's not the only factor. Convenience and flexibility also play a part.
| Consideration | Joint Policy | Two Single Policies |
|---|
| Simplicity | ✅ Winner. One application, one direct debit, one renewal process. | More initial paperwork and two separate payments to manage. |
| Flexibility | Less flexible. Changes (e.g., downgrading cover) affect the whole policy. | ✅ Winner. Each person can independently change, upgrade, or cancel their cover. |
| Separation | Can be administratively complex to split if the relationship ends. | ✅ Winner. No link between policies. No action is needed if you separate. |
| No Claims Discount | ❌ Major Drawback. A claim from one partner can reduce or reset the NCD for both people at renewal. | ✅ Winner. NCDs are entirely separate. One person's claim has zero impact on the other's premium. |
The No Claims Discount issue is a crucial, often overlooked, drawback of joint policies. If one partner has a significant claim, the NCD for both can be penalised, leading to a much larger premium increase at renewal for the person who didn't even claim.
Enhancing Your Wellbeing: The Added Value of Modern PMI
Today’s best PMI providers offer much more than just hospital treatment. They are evolving into holistic health partners, providing tools to help you stay well. These benefits are often included as standard.
- Digital GP Services: Get a GP appointment via your phone or laptop, often within hours, 24/7. This is a huge convenience, saving you a wait for an NHS appointment.
- Mental Health Support: Most policies now include access to telephone counselling or a set number of face-to-face therapy sessions without needing a GP referral.
- Wellness Programmes: Insurers like Vitality and YuLife actively reward healthy behaviour. You can get discounts on gym memberships, fitness trackers, and even your weekly shop for staying active.
- WeCovr's Exclusive Benefits: As a WeCovr client, you get even more value. We provide all our health and life insurance customers with complimentary access to CalorieHero, our AI-powered food diary and calorie tracking app. Furthermore, clients who purchase PMI through us are eligible for exclusive discounts on other policies, such as life insurance or income protection.
A Practical Checklist: How to Choose
Feeling unsure? Follow these simple steps to find the right path for you and your partner.
- Assess Your Individual Needs: Do you both want the same level of cover? Does one of you want extras like dental or mental health support?
- Note Your Ages and Health: Be honest about your age and any recent medical issues. This is the biggest driver of cost.
- Decide on a Budget: How much are you comfortable spending per month? What level of excess can you afford if you need to claim?
- Weigh Convenience vs. Flexibility: Is the simplicity of one policy more important to you than the flexibility and NCD protection of two single plans?
- Talk to an Independent Broker: This is the most important step. A specialist broker can do the hard work for you, running quotes for every possible combination and presenting you with the single cheapest option, whether that's a joint plan or two separate policies.
Can we have different levels of cover on a joint health insurance policy?
Yes, most UK insurers allow you to have different cover levels on a joint policy. For example, one partner could have a comprehensive plan with a low excess, while the other has a more basic level of cover with a higher excess. However, this customisation can make the policy more complex and may reduce the benefit of a joint plan. Often, two separate single policies achieve this more effectively and at a lower cost.
What happens to a joint private medical insurance policy if my partner and I separate?
If you separate, you will need to contact your insurer. Most will allow you to split the joint policy into two new single policies. However, this can be an administrative hassle. The insurer will reassess each person individually, and the new premiums will be based on your ages and claims history at that time. This is a key advantage of having two single policies from the start, as no action is needed if your relationship status changes.
Does making a claim on a joint policy affect the premium for both of us?
Yes, it typically does. Joint policies usually have a shared No Claims Discount (NCD). If one person makes a claim, the NCD for the entire policy is likely to be reduced at the next renewal. This means the premium will increase for both individuals, even the one who did not claim. This is a significant drawback compared to two single policies, where each person's NCD is protected independently.
Ready to Find the Best Value for You and Your Partner?
The question of joint vs. single private health insurance policies doesn't have a one-size-fits-all answer. While a joint policy offers simplicity, two separate single policies frequently provide better value and greater flexibility, especially if there's a difference in your ages or health needs.
The only way to find the truly optimal solution is to compare the entire market. Let WeCovr do the heavy lifting for you. Our expert advisors provide free, impartial, and personalised quotes to help you secure the right cover at the best possible price.
