Health Insurance for Pre-Existing Conditions UK

UK PMI treats pre-existing conditions in three ways. Moratorium underwriting excludes conditions you had symptoms of in the last 5 years, but returns them to cover after 24 continuous symptom-free/treatment-free months. Full Medical Underwriting (FMU) asks about your history at quote and permanently excludes stated conditions. Continued Personal Medical Exclusions (CPME) carries forward exclusions from an existing PMI when you switch insurer. PremierPMI benchmarks all three approaches across all seven UK insurers to find your best route.

Health Insurance for Pre-Existing Conditions: what the cover actually does

'Pre-existing condition' is UK PMI's most misunderstood term. Legally, it is any condition — diagnosed or not — that you had symptoms of, took medication for, or received advice about in a defined lookback period. On moratorium underwriting the lookback is 5 years; on FMU it is your entire medical history. The definition matters because it decides whether treatment for that condition is covered.

Three underwriting approaches exist. **Moratorium** (default on Bupa, Aviva, Vitality, WPA, Freedom, The Exeter): no medical questions at quote. Any condition symptomatic in the last 5 years is excluded, but returns to cover after you have been 24 continuous months symptom-free, treatment-free and medication-free while insured. **Full Medical Underwriting** (available on Bupa, AXA, Aviva, WPA, The Exeter): declare full history upfront, insurer confirms exactly what is excluded permanently. Better if you want certainty. **Continued Personal Medical Exclusions** (available across the market for switchers): your new insurer carries forward the exclusions from your existing PMI, letting you switch without new underwriting.

The right choice depends on your history. Well-controlled type 2 diabetes reversed by lifestyle — moratorium wins. A hip that has been fine for 3+ years but had a diagnosis 4 years ago — moratorium wins. Any chronic condition still being treated (bipolar, RA, MS, active cancer) — FMU or CPME, because moratorium will never bring it back into cover. Family history alone is NEVER a pre-existing condition — you cannot be excluded for something you have not had.

Which insurers tend to fit best

Before you buy — broker checklist

• Never lie or omit on a PMI application — non-disclosure voids future claims.
• Match underwriting to condition: moratorium for resolved history, FMU for certainty, CPME for switchers.
• For chronic conditions still being treated, moratorium will not return them to cover.
• Family history alone is NOT a pre-existing condition.
• Ask about the '24-month rule' before you buy — it is your route back to cover.
• The Exeter and WPA are your first stops for genuinely complex history.
• PremierPMI can benchmark all three approaches across all seven insurers before you buy.

PremierPMI broker desk notes

• About 40% of our applicants declare something pre-existing. The vast majority get placed on excellent terms — the problem is almost always the choice of underwriting, not the condition itself.
• The Exeter is the insurer we pitch first for tailored FMU on complex history. Their underwriters look at each case individually rather than applying blanket exclusions. WPA is close behind.
• CPME switches are underrated. If you have a policy with exclusions you have lived with for 5 years, a CPME switch can drop premium 15–25% while keeping your protection intact.
• The single biggest mistake we see: buying moratorium when you have an active chronic condition. It will not come back into cover. FMU with declared exclusions is almost always the honest answer.

Common questions

Can I get health insurance with a pre-existing condition?

Yes — all seven major UK PMI insurers will insure you. The pre-existing condition itself will be excluded (either temporarily on moratorium, or permanently on FMU) but you can still be fully covered for unrelated conditions.

What is moratorium underwriting?

Moratorium underwriting asks no medical questions at quote. Any condition you had symptoms of, treatment for or medication for in the last 5 years is excluded. That condition returns to cover after you have been 24 continuous months symptom-free, treatment-free and medication-free while insured.

What is Full Medical Underwriting (FMU)?

FMU requires you to declare your full medical history at quote. The insurer confirms exactly what is excluded, usually permanently. It offers certainty upfront and is often the right choice for chronic or complex conditions.

What is CPME?

Continued Personal Medical Exclusions is a switching mechanism. Your new insurer carries forward the exclusions from your existing PMI, letting you switch without new underwriting or losing built-up cover. All seven UK insurers accept CPME switches.

Which insurer is best for pre-existing conditions?

The Exeter Health+ and WPA Flexible Health lead the market for tailored FMU on complex history. Bupa By You is the strongest all-round choice for CPME switches and standard moratorium. PremierPMI benchmarks all three every time.

Does family history count as a pre-existing condition?

No. A pre-existing condition is something you personally have had symptoms of, treatment for or medication for. Family history of cancer, diabetes or heart disease does not itself count.

Will controlled diabetes or hypertension stop me getting PMI?

No — you can be covered, with the condition itself excluded. Moratorium will bring it back into cover after 24 months symptom-free (rare for chronic conditions on medication). See our dedicated diabetes and blood pressure pages.

What happens if I develop a new condition after taking PMI?

A condition that develops after your policy start date is fully covered — that is exactly what PMI is designed for. It only becomes 'pre-existing' if it was symptomatic before you took the policy out.
