TL;DR
While private medical insurance in the UK offers faster access to eligible treatments, it comes with limitations such as exclusions for chronic and pre-existing conditions, out-patient limits, and age-related premium increases. WeCovr is an FCA-regulated broking firm, and a specialist at WeCovr or one of its broker partners can help you navigate these drawbacks to find a suitable policy.
Key takeaways
- Standard policies usually exclude pre-existing medical conditions.
- Chronic condition management is generally not covered by PMI.
- Out-patient cover often has annual financial or session limits.
- Private healthcare does not cover A&E or emergency admissions.
- Premiums typically rise as you get older or make a claim.
When researching how much private health insurance costs, it is equally important to understand what a policy will not cover. The main disadvantages of private healthcare in the UK include exclusions for pre-existing and chronic conditions, out-patient limits, policy excesses, and the fact that premiums generally rise with age.
While private medical insurance (PMI) offers valuable access to private facilities and potentially shorter waiting times for eligible elective treatments, it is designed to work alongside the NHS rather than replace it entirely. WeCovr is an FCA-regulated broking firm, and a specialist at WeCovr or one of its broker partners can help you compare policies from a range of UK insurers, ensuring you understand both the benefits and the limitations before you apply.
Understanding the limitations of a policy is a vital part of how to choose private health insurance. Standard UK PMI is designed to cover acute conditions that start after your policy begins. An acute condition is a disease, illness, or injury that is likely to respond quickly to treatment and return you to your previous state of health.
Because of this core principle, several structural limitations apply to most private health insurance policies.
1. The exclusion of pre-existing conditions
One of the most significant drawbacks of private medical insurance is how it handles pre-existing conditions. If you have experienced symptoms, sought advice, or received treatment for a medical issue before your policy starts, it will usually be excluded from your cover.
How these exclusions are applied depends on the type of underwriting you choose:
- Moratorium Underwriting: You do not need to complete a detailed medical questionnaire upfront. Instead, the insurer typically excludes any condition you have had in the years immediately preceding the policy start date. These conditions may become eligible for cover later, provided you remain completely symptom- and treatment-free for a set continuous period (often two years) after the policy begins.
- Full Medical Underwriting: You provide your full medical history when you apply. The insurer will then explicitly list any excluded pre-existing conditions on your policy certificate from day one.
2. Chronic conditions are generally not covered
A chronic condition is a disease, illness, or injury that has one or more of the following characteristics: it needs ongoing or long-term monitoring, it has no known cure, or it requires you to be specially trained to cope with it. Common examples include asthma, diabetes, and arthritis.
Standard UK PMI is designed for acute conditions. Therefore, the ongoing management and routine monitoring of chronic conditions are generally not covered.
Illustrative Example: Imagine a policyholder who develops asthma after their policy begins. The insurer may cover the initial consultations and diagnostic tests required to diagnose the condition and stabilise it (as this is the acute phase). However, once the asthma is diagnosed as a chronic condition requiring ongoing inhalers and routine check-ups, the private cover for that specific condition will typically end, and the patient's ongoing care will be transferred to the NHS.
3. Out-patient limits and diagnostic shortfalls
While in-patient and day-patient care (where you require a hospital bed) are often covered comprehensively on core policies, out-patient care frequently comes with restrictions. Out-patient cover includes specialist consultations, diagnostic tests, and therapies (such as physiotherapy) where you do not need to be admitted to a hospital.
Many policies apply an annual financial limit to out-patient cover, or they may restrict therapies to a set number of sessions, which varies by insurer and policy. For instance, if you are researching private MRI scan costs, it is important to note that complex diagnostic scans can quickly consume a basic out-patient allowance. Once your out-patient limit is reached, you will need to self-fund any further out-patient care or return to the NHS for those services.
4. Emergency care remains the domain of the NHS
Private hospitals in the UK typically do not have Accident and Emergency (A&E) departments, and private medical insurance does not cover emergency treatment.
In any medical emergency, you must call 999 or go to your nearest NHS A&E. For urgent but non-life-threatening problems, you should contact NHS 111. In a mental health crisis, call 999, NHS 111 (mental health option), or the Samaritans on 116 123. After a road accident, call 999 if anyone is hurt or the road is dangerous.
Never tell a family member to contact your insurer, WeCovr, or a broker partner first in an emergency. Insurer contact comes afterwards—for example, to notify them of a claim or to pre-authorise follow-up elective treatment once the emergency has been resolved by the NHS.
5. Age-related premium increases and reviewable pricing
Private health insurance is an annually renewable contract, meaning your premiums are reviewable every year. It is a common misconception that your premium will stay the same. In reality, premiums typically rise at renewal due to several factors:
- Age: As you get older, the statistical likelihood of needing medical treatment increases.
- Medical Inflation: The cost of medical treatments, new drugs, and hospital facilities generally rises faster than standard inflation.
- Claims History: Depending on your policy terms, making a claim may reduce your no-claims discount, leading to a higher premium at renewal.
It is also important to remember that your cover ends if your premiums stop.
6. Excesses and consultant fee shortfalls
To lower their monthly premiums, many policyholders choose to add an excess to their policy. This is a set amount you agree to pay towards the cost of your private medical care. Depending on your policy terms, this excess may apply once per policy year or per individual claim.
Additionally, insurers maintain fee guidelines that dictate how much they will pay a consultant or surgeon for a specific procedure. If your chosen consultant charges more than the insurer's maximum fee, you may be responsible for paying the difference, known as a shortfall.
Comparing the limitations: What to watch out for
When reviewing policy documents, it helps to understand how different limitations might affect your out-of-pocket costs and your treatment journey.
| Policy Feature | How it typically works | Potential Disadvantage |
|---|---|---|
| Pre-existing Exclusions | Excludes conditions you had before the policy started. | You will need to rely on the NHS for any historical health issues. |
| Chronic Condition Rules | Cover stops once a condition is deemed incurable or requires ongoing management. | Long-term illnesses (e.g., diabetes) must be managed by the NHS. |
| Out-patient Limits | Caps the amount the insurer will pay for consultations and tests per year. | You may have to self-fund tests if you exceed your annual limit. |
| Policy Excess | You pay a set amount towards your claims. | Increases your out-of-pocket expenses when you need to use the policy. |
| Consultant Fee Limits | Insurers cap the amount they pay specialists. | You may face a shortfall if your specialist charges above the insurer's rate. |
How a broker can help you navigate these disadvantages
Reading through policy terms, underwriting rules, and exclusion lists can be complex. Because suitability depends entirely on your personal circumstances and medical history, seeking guidance can help you avoid unexpected surprises at the point of claim.
A specialist at WeCovr or one of its broker partners can help you compare policies from a range of UK insurers. They can explain how different insurers define chronic conditions, how out-patient limits work in practice, and which underwriting method may be a suitable option for your circumstances.
This service comes at no extra cost to you. WeCovr and its broker partners are usually paid a commission by the insurer when a policy is arranged. Most brokers on WeCovr's panel do not charge a separate fee for health insurance, but please confirm this with your broker before you buy.
