NHS waiting times remain a top worry for many households. While the NHS is free at the point of use, elective procedures, diagnostics, and mental health support can involve long queues. Private medical insurance (PMI) helps you skip waiting lists, access additional treatments (including some drugs not routinely available on the NHS), choose hospitals and consultants, and book scans quickly. But policies differ hugely on outpatient cover, hospital lists, cancer care, mental health, and exclusions—so the cheapest monthly premium can be the most expensive once you need care.
This 2025 buyer’s guide compares the best health insurance plans in the UK, explains how underwriting works (moratorium vs full medical), what affects your premium, and how to cut costs without losing key benefits. By the end, you’ll know which providers to shortlist, which add‑ons matter, and how to compare quotes like a pro.
How UK Health Insurance Works (2025 Essentials)
What private medical insurance (PMI) covers:
- Acute conditions (those that can get better) rather than chronic, long‑term management.
- In‑patient and day‑patient treatment (surgery, hospital accommodation).
- Diagnostics and outpatient specialist consultations (if included).
- Cancer care pathways (chemo, radiotherapy, targeted therapies—varies by insurer).
- Mental health support (therapy, psychiatry—session limits often apply).
- Optional extras (dental/optical, travel cover, therapies, private GP).
What PMI typically doesn’t cover:
- Routine pregnancy and childbirth (complications may be covered).
- Chronic condition maintenance (e.g., long‑term diabetes management).
- GP services (unless your plan includes a virtual or private GP add‑on).
- Emergency care (you’ll still use NHS A&E; some plans include limited emergency abroad cover).
Underwriting methods:
- Moratorium (MORI): No medical questionnaire. Pre‑existing conditions from the past 5 years are excluded initially; if you have no symptoms, medication, advice, or treatment for 2 continuous years after the policy start, cover may be restored automatically.
- Full Medical Underwriting (FMU): You disclose your history up front. Insurer accepts with specific exclusions and/or loadings—or covers outright.
- Switch/CPME (Continued Personal Medical Exclusions): For switching from an existing policy; aims to carry forward your exclusions so you don’t “reset” the clock.
Excess and claims:
- You select an excess (e.g., £100–£500+). It’s the amount you pay towards a claim per person per policy year (or per claim, depending on insurer).
- Pre‑authorisation: Get a GP/open referral, call your insurer for authorisation, and use approved hospitals/consultants.
Hospital lists:
- Standard vs Extended/Central London lists. London teaching/private hospitals command higher premiums.
- Guided care (insurer helps select consultants) often reduces cost.
Best Health Insurance Providers in the UK (2025 Shortlist)
Below is an at‑a‑glance comparison of major PMI brands. “Best for” is directional—your best option depends on age, region, claims history, underwriting, and benefits required.
| Insurer | Best For | Stand‑Out Features | Watch‑Outs |
|---|---|---|---|
| Bupa | Diagnostics & hospital access | Direct Access (some conditions without GP referral), strong cancer cover, digital tools | London list increases premium; check outpatient caps |
| AXA Health | Value + guided care | Guided consultant option, good therapies cover, strong SME options | Hospital list selection matters (Central London adds cost) |
| Aviva | Flexible modular cover | “MyAviva” app, bolt‑ons for mental health/dental/optical; good renewal incentives | Outpatient caps vary; check excess per policy year |
| Vitality | Wellness + rewards | Apple Watch/Gym/retailer rewards, strong digital GP, travel cover add‑on | Rewards best if you actively engage; read activity requirements |

| Freedom Health | Budget flexibility | Options to tailor outpatient and London access | More basic cancer/mental health on lower tiers |
| Benenden Health (not PMI) | Low‑cost supplementary cover | Diagnosis/treatment support, does not underwrite age/conditions | Not full PMI; works alongside NHS, not a like‑for‑like replacement |
| Saga (50+) | Over‑50s | Benefits tailored to seniors, service focus | Age‑based premiums—compare carefully to mainstream brands |
Tip: Use an FCA‑authorised broker to get like‑for‑like quotes across hospital lists, outpatient caps, excess levels, and underwriting type.

Cover Levels Explained (Choose What You’ll Actually Use)
In‑patient & Day‑patient (Core)
- Hospital accommodation, theatre fees, surgeons, anaesthetists.
- Often unlimited on most comprehensive plans.
Out‑patient (Diagnostics & Consultations)
- Specialist consultations, diagnostic tests (MRI/CT/PET scans), blood tests, X‑rays.
- Options: no out‑patient, limited (e.g., £500/£1,000/£1,500), or full out‑patient.
- Practical tip: If your priority is fast diagnosis, don’t skimp here—consider at least £1,000–£1,500 OP.
Cancer Care
- Chemo/radiotherapy, surgery, cancer‑related out‑patients.
- Check: Access to drugs not routinely commissioned by the NHS (subject to clinical eligibility), home chemo, wig/prosthesis benefits, end‑of‑life care.
Mental Health
- Out‑patient therapy sessions (CBT, counselling), psychiatrist consultations, in‑patient mental health (days per year).
- Check: Number of sessions, referral rules, and whether remote therapy is included.
Therapies & Alternative Treatments
- Physiotherapy, osteopathy, chiropractic; acupuncture (varies).
- Caps per course or policy year; sometimes requires GP/consultant referral.
Dental & Optical (Optional)
- Routine check‑ups, hygienist, fillings, crowns; optical tests and frames/contact lenses.
- Often more cost‑effective via specialist dental plans—compare standalone vs PMI add‑on.
Travel & Worldwide
- Optional worldwide travel cover (Vitality offers a popular add‑on); emergency medical abroad, cancellation, baggage.
- If you already have travel insurance, avoid duplication.
Underwriting Deep Dive: Moratorium vs FMU vs Switch (CPME)
- Moratorium
- No medical forms; faster to start.
- Excludes pre‑existing conditions with symptoms/treatment/medication/advice in the last 5 years.
- If you remain symptom‑, medication‑, and treatment‑free for 2 continuous years after start, the condition may become eligible.
- FMU
- Complete medical questionnaire; insurer outlines specific exclusions up front.
- Can provide certainty for some conditions that moratorium might otherwise block.
- Switch/CPME
- For those already insured privately; preserves current exclusions and often avoids new medical underwriting.
- Useful to avoid re‑starting moratorium clocks.
Tip: If you have a specific pre‑existing condition you want considered, speak to a broker about FMU and specialist underwriters who may cover it with terms.
How Much Does UK Health Insurance Cost in 2025?
Premiums depend on:
- Age (older = higher premium)
- Postcode (London and SE often cost more)
- Hospital list (including or excluding Central London)
- Out‑patient level (none/limited/full)
- Mental health/cancer enhancements
- Excess amount (£0/£100/£250/£500+)
- Underwriting (switch vs new; claims history)
- Add‑ons (dental/optical, travel)
Indicative patterns (illustrative only; not quotes):
- 30‑year‑old, outside London, mid‑tier out‑patient, £250 excess: mid‑£30s–£60s/month depending on brand and options.
- Family of four, mixed ages, guided care, £250 excess: £110–£220+/month depending on out‑patient and hospital list.
- Over‑50s comprehensive with full out‑patient and London list: can exceed £100–£200+/month.
Money‑saving levers:
- Increase excess to £250–£500 (ensure you can afford it).
- Choose guided consultant option instead of open choice.
- Select a restricted hospital list (exclude Central London) if you don’t need it.
- Pick a limited out‑patient cap (e.g., £1,000–£1,500) rather than full out‑patient.
- Opt for the “6‑week option” (use NHS if treatment is available within 6 weeks; go private if not).
- Pay annually (some offer small discounts) and use no‑claims discounts where offered.
Cancer Cover: The Questions to Ask
- Are licensed cancer drugs not routinely commissioned by the NHS covered if clinically eligible?
- Is there a monetary/time limit on cancer treatment?
- Are follow‑up scans, tests, and consultant reviews included after initial treatment?
- Is home chemotherapy covered?
- Are wigs/prostheses and complementary therapies included?
Bupa, AXA, Vitality, Aviva, WPA all provide comprehensive cancer pathways on higher tiers—read each insurer’s “cancer promise” wording.
Mental Health: Growing, But Read the Small Print
- Session caps: Many plans cap therapy (e.g., up to 8/12/20 sessions per year).
- Psychiatrist vs psychologist/therapist: Coverage rules and referral pathways differ.
- Remote therapy: Often included; convenient and quick.
- In‑patient mental health: Days per year vary widely; confirm.
If mental health is a priority, price a plan with a higher therapy session allowance and clear referral rules.
Hospital Lists & London Weighting
- Standard lists: Good coverage at reputable private hospitals nationwide.
- Extended/Central London lists: Access to premium providers (e.g., HCA, Cleveland Clinic London, some teaching hospitals).
- Guided option: You receive a shortlist of consultants/hospitals from the insurer in your region—often significantly cheaper.
Choose a list aligned to where you’d actually get treated. If you live outside London and don’t plan to travel for care, a standard list may suffice.
The “6‑Week Option” Explained
- If the NHS can provide your in‑patient/day‑patient treatment within 6 weeks, you use the NHS; if not, you go private.
- Often reduces premium meaningfully.
- Good compromise if you’re primarily concerned about very long waits, not every wait.
Family & Life Stage Tips
Families with young children
- Out‑patient diagnostics matter (quick paediatric referrals, scans)
- Consider a mid‑to‑high out‑patient cap
- Mental health and therapies (physio, speech & language) can be valuable
Over‑50s/retirees

Students/young adults
- Entry‑level plans with limited out‑patient & guided care can be affordable
- Virtual GP access and mental health support are useful

FAQs: Best Health Insurance Plans in the UK (2025)
Q1: Which is the best health insurance provider in the UK for 2025?
A1: There’s no universal “best”—it depends on your location, age, and benefits needed. Bupa and AXA Health offer broad networks and strong cancer care; Aviva is flexible and competitively priced; Vitality suits wellness‑focused members; WPA and The Exeter offer transparent, modular options. Compare like‑for‑like benefits (out‑patient, hospital list, excess) before deciding.Q2: How much does UK health insurance cost per month?
A2: Premiums vary by age, postcode, cover level, and hospital list. As a rough guide, a 30‑year‑old outside London on mid‑tier cover with £250 excess might pay mid‑£30s–£60s/month; over‑50s comprehensive cover can exceed £100–£200+. Get personalised quotes.Q3: Is out‑patient cover worth it?
A3: If you want fast diagnosis (scans, tests, specialist consultations), yes—consider at least £1,000–£1,500 out‑patient cover. In‑patient‑only plans are cheaper but often require you to get diagnostics via the NHS first.Q4: Will health insurance cover pre‑existing conditions?
A4: Usually not at the start. Under moratorium underwriting, conditions with symptoms/treatment in the last 5 years are initially excluded but may be covered after 2 symptom‑free years. With FMU, the insurer may apply named exclusions. If switching from an existing policy, CPME can preserve your status.Q5: What’s the 6‑week option and should I take it?
A5: If the NHS can treat you within 6 weeks, you use the NHS; if not, you go private. It lowers premiums and suits members mainly worried about very long waits, not every wait.Q6: Do plans include dental, optical, and GP services?
A6: Only if you add them. Many policies offer dental/optical add‑ons and virtual GP access. Compare against standalone dental or cash plans to avoid paying more for less.Q7: Can I use private insurance for emergencies?
A7: No—PMI is not for emergency A&E. Use the NHS for emergencies. PMI covers planned acute care, diagnostics, and elective procedures (subject to authorisation).Q8: How do I switch insurers without losing cover?
A8: Ask for a CPME (switch) quotation. This aims to carry over your existing exclusions and avoid restarting moratorium periods. Provide your current certificate and claims history.Pick Confidently, Cover What Matters
The best health insurance plans in the UK for 2025 balance price with the benefits you’ll actually use—fast diagnostics, strong cancer care, adequate mental health support, and a hospital list that fits where you live.
