HENRY PMI: when £2,400/year cover is worse value than paying £18k cash for a hip

For High Earner Not Rich Yet buyers with no medical history, the arithmetic behind PMI is more nuanced than the brochures suggest. Seven years of premium equals one private hip. Here is when that maths tilts.

The short answer

• Comprehensive PMI for a healthy 42-year-old in a top London postcode averages £2,400/year
• A private hip replacement package at a top London hospital averages £17,800–£19,400
• Seven years of premiums pays for one hip — on paper, PMI 'breaks even' if you claim once per decade
• But PMI's true value is the £75k+ tail (cancer, cardiac, complex spinal) that self-pay cannot absorb

The uncomfortable arithmetic

For the HENRY (High Earner Not Rich Yet) buyer — a professional aged 35–50, earning £120k–£250k, healthy, London-based, with liquid savings but not deep enough net worth to self-insure catastrophic events — the PMI decision is not obvious. On a naive premium-versus-single-procedure basis, PMI often looks like a bad trade.

Seven-year PMI cost vs single self-pay procedures, London 2026

• Comprehensive PMI premium, healthy 42yo London: £2,400/yr (PremierPMI benchmark, June 2026)
• Average number of years between private orthopaedic procedures, HENRY cohort: 9.4
• Median oncology pathway cost, self-pay: £78,400

The tail is what you pay for

PMI is not a savings account for elective procedures. It is a hedge against catastrophic-cost pathways where the total bill exceeds what any HENRY balance sheet can absorb without genuine damage. A completed cancer pathway with modern targeted therapies runs £75,000–£240,000. A complex spinal fusion with post-op rehab runs £45,000–£110,000. A three-vessel cardiac bypass at a top London hospital runs £60,000–£90,000. PMI exists precisely to make those events not-a-financial-decision.

"The client who ends up regretting a self-pay decision is never the one who paid £18k for a hip. It is the one who deferred PMI 'because I'm healthy' and got a stage 2 breast cancer diagnosis eight years later, then paid £180k out of a £320k liquid position before treatment was complete." — Tumaris Rahimova, Head of Operations, PremierPMI

The four HENRY profiles and what wins

• Single, £150k, no dependents, £200k liquid: self-pay the small stuff, catastrophic cover only (a WPA cash-plan or an AXA high-excess plan works).
• Couple, £250k joint, no children, £400k liquid: full comprehensive PMI for both — the numbers cross over sharply above two people.
• Family with children, £220k, £150k liquid: full comprehensive family PMI is a no-brainer. Paediatric cover is where the value density is highest.
• Pre-retiree, £300k+, £1.2m liquid: reassess. At high net worth the case for PMI weakens — but a catastrophic-only, high-excess policy is still the intelligent hedge.
