CPME Underwriting Explained

CPME (Continuous Personal Medical Exclusions) is the underwriting method used when switching UK private medical insurance from one insurer to another. Instead of restarting the underwriting clock — which would exclude your existing conditions all over again — the new insurer accepts the existing scheme's underwriting decisions unchanged. Result: you keep cover for everything you were previously covered for, at a new (often lower) premium.

CPME Underwriting: what the cover actually does

CPME sits alongside three other UK underwriting types. Moratorium (M) — the insurer auto-excludes any condition you had symptoms/treatment/medication for in the past 5 years, for a rolling 2 years after joining. Medical History Declaration (MHD) — you declare your medical history and the insurer prices/excludes accordingly. Full Medical Underwriting (FMU) — full clinical questionnaire, most accurate, day-one clarity on what's covered. Continuous Personal Medical Exclusions (CPME) — used only on switch, preserves the outcome of whichever method your existing scheme used.

Why does CPME matter? Because switching insurer is the single most powerful cost-saving lever in UK PMI. A five-year-tenured individual or group scheme with no benchmarking is typically 15–30% over-market. But without CPME, switching would mean losing cover for any condition treated during your tenure — a devastating loss for anyone with a chronic condition, past cancer diagnosis, or long-term musculoskeletal issue. CPME neutralises that risk.

CPME is available across all seven major UK PMI insurers (Bupa, AXA, Aviva, Vitality, WPA, Freedom, The Exeter) both for individual and group schemes. Some insurers (Bupa, AXA) are more restrictive on which exclusions they accept via CPME — occasionally a chronic condition is re-underwritten. We manage the CPME data-transfer form for every client switch, and always confirm the new insurer's underwriting acceptance letter before recommending the move.

Which insurers tend to fit best

Before you buy — broker checklist

• Confirm your existing scheme is at least 12 months in force — some insurers won't accept CPME on very new policies.
• Ask your current insurer for a CPME data-transfer statement per member.
• Cross-check the new insurer's acceptance letter before cancelling the incumbent.
• Understand which exclusions transfer as-is vs may be reassessed.
• Time the switch to your renewal date to avoid loss-of-underwriting gaps.
• Have us handle the paperwork — a single mismatched exclusion can invalidate months of savings.

PremierPMI broker desk notes

• CPME is only as good as the data quality — always request the CPME statement in writing from the incumbent insurer, don't rely on memory or assumptions. A miscopied exclusion can leave a member uncovered.
• For group scheme switches with 50+ lives, we run a member-by-member CPME reconciliation. It takes 3–5 days of extra work but eliminates the risk of any employee losing cover for an existing condition.
• Never switch scheme just before a planned treatment — even with CPME, the new insurer may require pre-authorisation processes that take 2–4 weeks. Time switches for stable periods.

How PremierPMI places this cover

CPME switches are where broker experience pays for itself: a single miscopied exclusion can leave a member uncovered mid-treatment. PremierPMI (Tesha Family Ltd, FRN 1029667) requests the CPME data-transfer statement from the incumbent in writing, cross-checks it against the new insurer's underwriting acceptance letter before any policy is cancelled, handles moratorium/MHD/FMU reconciliation per member on group schemes, and gives every switched client a named claims escalation route from the moment the new policy incepts. Advice and placement are free — we're paid by the insurer, never by you.

Common questions

What does CPME stand for?

Continuous Personal Medical Exclusions. It's the UK PMI industry's mechanism for switching health insurance without restarting medical underwriting — the new insurer accepts the existing scheme's underwriting decisions unchanged.

How does CPME differ from moratorium underwriting?

Moratorium is a starting underwriting method — the insurer auto-excludes recent conditions for a rolling 2 years. CPME is a switching method — used only when moving between insurers, it preserves whatever underwriting method (moratorium, MHD or FMU) was used originally.

Does every UK insurer accept CPME?

All seven major UK PMI insurers (Bupa, AXA, Aviva, Vitality, WPA, Freedom, The Exeter) accept CPME in principle. Individual insurers have varying acceptance criteria for chronic conditions — some may re-underwrite specific exclusions. We check per-case before recommending a switch.

Can I switch mid-year using CPME?

You can, but you typically pay two months of overlap or lose part of the annual premium. We recommend timing switches to renewal date (or the annual cancellation window on individual policies) to avoid financial waste.

Are there conditions CPME won't cover?

Occasionally an insurer will re-underwrite a chronic condition (like Type 2 diabetes or heart disease) on switch — meaning it's re-examined rather than accepted as-is. We confirm underwriting acceptance in writing before any switch, so there's no surprise.

Do I need to switch to save money?

Not always. Sometimes we negotiate a better renewal with the incumbent by benchmarking against the market. But if the incumbent won't move to a competitive price and CPME is available, switching is usually the right answer.

Is CPME available for group schemes?

Yes — for groups of 2 to 10,000+ lives. Each covered employee's underwriting transfers individually via a CPME data-transfer statement. We manage the reconciliation for every group placement.

What if my existing insurer refuses to release CPME data?

They can't refuse under standard PMI industry practice — CPME data belongs to the member/employer, not the insurer. If there's ever pushback, we escalate via the PMI Data Transfer Protocol which is industry-standard practice. This has never failed us in 40+ years.

How long does a CPME switch take?

Individual switches: 5–10 working days. SME group switches: 2–4 weeks. Corporate group switches: 6–12 weeks including employee communication and admin migration.
