Private health insurance can provide quicker access to treatment, specialist care, and private hospital facilities — but not all policies offer the same level of cover. With terms like "inpatient," "outpatient," and "comprehensive" thrown around, it’s crucial to understand what each type actually includes so you can choose the most suitable plan.
In this guide, we break down the key health insurance policy types available in the UK, explain how they work, and help you decide which level of cover is best for your personal and financial situation.
Why Understanding Policy Types Matters
Choosing the wrong policy could mean you're either overpaying for features you won’t use or underinsured when you need treatment. Health insurance isn’t one-size-fits-all — especially when policies can vary so widely between providers.
Understanding your options means you can:
Get the right level of cover for your health and lifestyle
Avoid unexpected exclusions or costs when claiming
Reduce your premiums by excluding services you don't need
Compare policies more accurately
The Four Main Types of UK Health Insurance Cover
Private medical insurance in the UK can be broken down into four broad categories:
1. Comprehensive Cover
What it includes:
Inpatient and outpatient care
Diagnostic tests, scans, consultations
Hospital stays and surgeries
Mental health support (where included)
Additional services such as physiotherapy, cancer treatment, and private GP access
Pros:
Most complete cover available
Best suited for people with ongoing health concerns or who want full peace of mind
Cons:
Most expensive option
May include cover for services you don’t necessarily need
Best for:
Those who want minimal waiting times and maximum choice over their care.
2. Inpatient-Only Cover
What it includes:
Treatment requiring a hospital stay (e.g. surgery)
Hospital accommodation, nursing, and related costs
Specialist fees for in-hospital procedures
What it excludes:
Outpatient tests, consultations, and follow-ups
Pros:
Affordable middle-ground option
Still protects against major health events or surgery costs
Cons:
You'll still need to rely on the NHS for diagnostics and follow-up appointments
Best for:
People who want protection for serious conditions but can tolerate NHS waiting times for diagnostics.
3. Outpatient-Only Cover (rare as a standalone product)
Outpatient-only cover is usually offered as an add-on rather than a standalone policy. It supplements inpatient cover by adding:
Consultations with specialists
Diagnostic tests and scans
Pre- and post-treatment appointments
Note: Most providers let you cap or remove outpatient benefits to adjust your premium.
4. Modular or Customised Health Insurance
Many insurers now offer modular policies, where you choose the exact cover you want. You typically start with core inpatient cover, then add modules like:
Outpatient care
Mental health services
Cancer treatment beyond NHS provision
Dental and optical care
Therapies (e.g. acupuncture, physiotherapy)
Travel or overseas treatment
Pros:
Flexibility to build your ideal plan
Pay only for what you need
Cons:
Can become expensive if you add too many modules
Requires careful review to avoid missing essential cover
Providers offering modular plans include:Bupa, AXA Health, Aviva, and Vitality.
Key Terms You Need to Know
When comparing policy types, you’ll come across terms that impact both your premium and your ability to claim. Here's what they mean:
Policy Excess
The amount you pay towards a claim. A higher excess usually means lower monthly premiums.
No Claims Discount (NCD)
A reward for not claiming, which may reduce your renewal premium.
Moratorium Underwriting
Your insurer won’t cover pre-existing conditions unless you’ve been symptom- and treatment-free for a set period (usually 2 years).
Full Medical Underwriting
Requires full disclosure of your medical history. The insurer then decides what will and won't be covered from the start.
Comparing Health Insurance Policy Types: What Matters Most
When choosing a policy type, consider the following:
1. Your Budget
Inpatient-only policies are cheaper than comprehensive ones
Modular plans allow better control over monthly costs
2. Your Health History
If you have no major conditions, a lower level of cover may be fine
If you have a family history of serious illness, more extensive cover may be advisable
3. Your Tolerance for NHS Waiting Times
If you’re happy to use the NHS for diagnosis, you may only need inpatient cover
If you want fast diagnostics and scans, outpatient modules are essential
4. Location
London and urban areas often have wider private hospital access
In rural regions, consider checking if your local private hospital is included in the insurer’s network
Example Scenarios: Which Cover Type Works Best?
Scenario 1:
"I’m healthy, in my 30s, and want protection against serious illness."→ Go for inpatient-only cover with a high excess to keep costs down.
Scenario 2:
"I run a business and can't afford delays in diagnosis or treatment."→ Choose a modular policy with inpatient + outpatient + digital GP + mental health.
Scenario 3:
"I have a chronic condition but want faster treatment for unrelated issues."→ Consider full medical underwriting to clarify exactly what’s covered.
Overlooked Tip:
Some policies offer "six-week NHS wait" options — your private cover only kicks in if the NHS wait exceeds six weeks. This can cut premiums by 20–30%.
How to Reduce Costs Regardless of Policy Type
Increase your excess — but only to a level you could afford
Exclude outpatient care or apply a cap if you're comfortable using the NHS for diagnosis
Choose a guided hospital list (i.e. let your insurer choose where you're treated)
Pay annually instead of monthly for a small discount
Use no-claims discounts wisely — sometimes it’s cheaper long-term not to claim for minor treatments
FAQs: Health Insurance Policy Types in the UK
What is the difference between inpatient and outpatient cover?
Inpatient cover refers to treatment that involves a hospital stay, while outpatient cover includes consultations, tests, and scans that don’t require overnight admission.
Is comprehensive health insurance worth it?
It depends on your needs. If you want minimal NHS involvement, comprehensive cover offers peace of mind but comes at a higher cost. If you're budget-conscious, inpatient-only may be sufficient.
Can I switch from inpatient-only to comprehensive later?
Yes, but you may be subject to new underwriting, waiting periods, and potential exclusions — especially for new or developing conditions.
Are modular health insurance plans more expensive?
Not always. They can be cost-effective if you only add the cover you need. However, adding every available module can make them more expensive than bundled comprehensive plans.
Will private health insurance cover emergency treatment?
No. Emergencies like A&E visits and ambulance services are covered by the NHS. Private insurance is designed for planned or elective treatments.
Final Thoughts
Understanding the different types of private health insurance is essential if you're considering going beyond NHS care. Whether you want full protection or a safety net for big health events, the right policy type depends on your needs, preferences, and budget.
Don’t just focus on price — focus on value. Take time to compare not only providers, but policy structures, excess levels, and exclusions. With the right knowledge, you can tailor your cover to suit your lifestyle and make private health insurance work for you — without paying for unnecessary extras.
