Aviva vs AXA Health health insurance — broker comparison

A side-by-side comparison of Aviva and AXA Health UK private medical insurance, written by the brokers who place both. We compare hospital networks, underwriting, outpatient and mental-health limits, and where each insurer wins on renewal.

At a glance

Where Aviva wins

• Fast-track physio & mental health referral without needing a GP letter (self-referral pathway).
• GP24 video service is genuinely useful — bookable inside MyAviva, prescriptions filled digitally.
• Overseas travel cover included on most tiers up to 120 days per trip (subject to policy).

Where AXA Health wins

• Fast Track Appointments — AXA books your specialist for you, no GP referral needed for many musculoskeletal, gynaecological and mental-health complaints.
• Working Body physiotherapy — self-referral, 6 sessions per condition per year on Comprehensive.
• Mind Health service — day-one triage with a clinician, up to 6 CBT sessions or onward referral.

Aviva watch-outs

• Consultant fee shortfalls: Aviva pays 'reasonable and customary' — a small number of London consultants charge above this. Ask for a fee estimate before booking.
• Chronic conditions are, as with all UK PMI, excluded once diagnosed and stable — Aviva's definition is broadly in line with the ABI.
• Extended Cover Plus roughly adds 20–35% to premium in London postcodes — worth it only if you want central-London HCA access.

AXA Health watch-outs

• AXA is rarely the cheapest headline premium — you're paying for the Fast Track service.
• Diagnostic scans done outside AXA's network may only be reimbursed at 'reasonable and customary' rates — always call the pre-auth line first.
• Extended hospital list uplift in London postcodes can be material — get both quotes and compare.

Hospital access compared

Aviva: Aviva runs three tiers: Key Hospital List (network only, cheapest), Directory (broadest UK network, most policies default here), and Extended Cover Plus (adds central-London HCA sites — vital if you want The Wellington, The Harley Street Clinic or The Princess Grace).

AXA Health: AXA uses Guided (network only, most affordable), Standard (broad national coverage) and Extended (adds top-tier central-London HCA hospitals). We usually recommend Standard for clients outside the M25 and Extended for those in central-London postcodes who specifically want HCA access.

PremierPMI verdict

Aviva remains our workhorse recommendation for individual and family PMI where a client wants breadth, a solid app and predictable renewal behaviour. It's rarely the cheapest and rarely the most premium — it's the balanced middle, and that's why we place so much of it.

If speed of access matters — and for most working-age professionals it does — AXA Health is the strongest whole-of-market recommendation we make. You pay a modest premium over Aviva to get the fastest specialist booking journey in UK PMI.

• Choose Aviva if: Balanced family PMI with strong app + digital GP.
• Choose AXA Health if: Fastest specialist access + strongest muscle-joint pathway.
• Both are placed whole-of-market by PremierPMI — we quote each side by side so you compare like for like before you commit.
