Private Medical Insurance vs Health Cash Plan UK 2026: Which to Buy?
Private Medical Insurance (PMI) and health cash plans are often confused but serve very different purposes. PMI pays for major private treatment and faster access to specialists; a cash plan pays small fixed sums toward everyday healthcare costs. Here is how they compare for 2026.
TL;DR - 30-Second Summary
- - PMI: covers full cost of private diagnosis and treatment for acute conditions, faster access than NHS, £30-£100+/month
- - Health cash plan: fixed cash payouts for routine costs (dental, optical, physio), does not cover major treatment, £5-£20/month
- - Many people hold both: PMI for major treatment, cash plan for everyday costs
Side by Side: PMI vs Health Cash Plan
| Feature | Private Medical Insurance | Health Cash Plan |

| Covers major treatment/surgery | Yes — full cost up to policy limits | No |
| Faster access than NHS | Yes — key benefit | No |
| Typical monthly cost | £30-£100+/month | £5-£20/month |
| Medical underwriting | Full medical or moratorium underwriting | Minimal or none |
| Everyday costs (dental, optical, physio) | Usually excluded or add-on only | Core benefit |
| Employer P11D benefit if provided | Yes — significant taxable value | Yes — small taxable value |
What Is Private Medical Insurance?
Private Medical Insurance pays for the cost of private diagnosis and treatment of acute (curable, short-term) medical conditions — consultations with specialists, diagnostic scans, and surgery, along with private hospital accommodation. The core value proposition is speed: private treatment is generally accessed within days or weeks, compared to potentially months on an NHS waiting list for non-urgent conditions.
PMI does not typically cover chronic conditions, pre-existing conditions, routine maternity care, or emergency treatment (which remains an NHS responsibility), and premiums rise with age and claims history.
What Is a Health Cash Plan?
A health cash plan reimburses a fixed cash amount toward the cost of routine, predictable healthcare — dental check-ups and treatment, eye tests and glasses, physiotherapy, chiropody and sometimes complementary therapies — regardless of whether treatment was NHS or private. It does not cover major surgery, cancer treatment, or hospital stays, and payouts are capped per category per year.
Who Should Choose What?
Choose PMI if...
- - You want faster access to specialists and treatment than the NHS
- - You can afford £30-£100+/month and want protection against large medical bills
- - You want the certainty of full treatment costs covered, not a small cash sum
Choose a health cash plan if...
- - You want low-cost help with everyday healthcare costs
- - You rely on the NHS for major treatment but pay privately for dental/optical/physio
- - You want a policy with little or no medical underwriting
Frequently Asked Questions
What is the main difference between PMI and a health cash plan?
Private Medical Insurance (PMI) pays for the actual cost of private diagnosis and treatment for acute conditions — consultations, scans, surgery, and hospital stays — potentially covering tens of thousands of pounds for major treatment. A health cash plan pays a small fixed cash sum toward routine, predictable costs like dental check-ups, opticians and physiotherapy, and does not cover major medical treatment or surgery at all.
How much does private medical insurance cost compared to a cash plan?
PMI typically costs from around £30-£100+/month for an individual depending on age, cover level, excess and underwriting type, and can be significantly more for older applicants or comprehensive cover. A health cash plan is far cheaper, usually £5-£20/month, because it pays modest fixed amounts rather than covering the full cost of major treatment.
Does PMI let me skip NHS waiting lists?
Yes, this is the primary reason people buy PMI — it gives access to private consultants, diagnostics and treatment, usually within days or weeks rather than the months-long waits sometimes seen on the NHS for non-urgent conditions. A cash plan does not provide this benefit; it simply reimburses a small amount toward costs, whether NHS or private.

Does either policy cover pre-existing conditions?
Generally no. Both PMI and cash plans exclude pre-existing conditions, though the underwriting approach differs — PMI insurers typically use either full medical underwriting (specific conditions excluded based on your health history) or moratorium underwriting (conditions from the past 5 years excluded for the first 2 years, then potentially covered if symptom-free). Cash plans usually apply simpler exclusions with less individual underwriting.
Can I have both PMI and a health cash plan?
Yes, and many people do — PMI for major treatment and fast access to specialists, and a cash plan for the everyday costs PMI typically excludes (routine dental, opticians, physiotherapy). The combined monthly cost is still often much lower than the potential cost of paying privately for both types of care without any cover.
Does PMI cover GP visits and prescriptions?
Not usually — PMI is designed for acute, treatable conditions requiring specialist or hospital care, not routine GP consultations or ongoing prescription costs, which remain covered by the NHS (free GP visits, and prescription charges in England unless exempt). Some premium PMI policies now include GP helplines or limited outpatient GP-style services as an add-on.
Is PMI worth it if I am young and healthy?
It depends on priorities. Young, healthy people are less likely to need major treatment soon, so many choose a cash plan (or nothing) instead of full PMI. However, some opt for PMI anyway to lock in lower premiums before age-related price increases and pre-existing condition exclusions accumulate, and to guarantee fast access to treatment if something unexpected arises.
Does employer-provided PMI count as a taxable benefit?
Yes. If your employer pays for your private medical insurance, it is treated as a Benefit in Kind and reported on a P11D, meaning you pay income tax on the value of the premium and your employer pays Class 1A National Insurance on it. A health cash plan provided by an employer is typically much lower value and therefore a smaller taxable benefit, though it is still usually reportable.
