Health Insurance for Diabetes

Existing diabetes is a pre-existing condition on UK PMI — the diabetes itself and its direct maintenance (insulin, HbA1c monitoring) is excluded. However, unrelated conditions, and often diabetes complications (diabetic retinopathy, cardiac, neuropathy) are covered subject to underwriting. Moratorium underwriting can accept diabetes back into cover after two symptom-free years. WPA and The Exeter are typically most flexible for diabetic applicants.

Health Insurance for Diabetes: what the cover actually does

Around 4.4 million people in the UK live with diabetes (Diabetes UK 2024). Type 2 accounts for ~90%, type 1 ~8%, other rarer forms ~2%. PMI is designed for acute treatment, not chronic disease management, so ongoing diabetes care itself is not what UK health insurance is built to fund. However, there are important nuances that make PMI valuable for diabetic applicants.

The two underwriting approaches produce very different outcomes. Full Medical Underwriting (FMU) asks about diabetes at quote and typically permanently excludes it and directly related complications. Moratorium underwriting excludes any condition you have had symptoms of or treatment for in the last 5 years — but can accept that condition back into cover after you have been symptom-free and treatment-free for 2 continuous years. For well-controlled type 2 diabetes, moratorium is often the better choice.

What PMI does cover, even for diabetics: unrelated illnesses (cancer, orthopaedic surgery, mental health, ENT), and often complications where the causal link is medically debatable (cardiac events, retinopathy on some policies). Consultant-led diabetes care through private endocrinologists is available on a self-pay basis and some insurers (WPA, The Exeter) will consider it under moratorium once the two-year rule is met.

Which insurers tend to fit best

Before you buy — broker checklist

• Prefer moratorium underwriting for well-controlled type 2 diabetes.
• Ask about the '24-month rule' — this is what returns diabetes to cover.
• Confirm whether direct complications (retinopathy, neuropathy, cardiac) are covered.
• For type 1, expect permanent exclusion of the diabetes itself — value is in unrelated cover.
• Ask about diabetic-friendly reward programmes (Vitality HbA1c targets).
• Consider WPA or The Exeter first — both are known for individualised underwriting.
• Never lie or omit — non-disclosure will void claims. Always tell the adviser everything.

PremierPMI broker desk notes

• About one in seven of our PMI applicants has type 2 diabetes. Nine times out of ten, moratorium underwriting is the right choice — it keeps the door open for future re-inclusion.
• The Exeter Health+ is our first port of call for type 1 diabetics who want proper cover. Their tailored FMU is more nuanced than the market default.
• For a diabetic applicant with well-controlled HbA1c under 53 mmol/mol, we can often place cover in the same premium band as a non-diabetic — the diagnosis matters less than the control.
• Never confuse PMI with chronic-condition care. If your priority is subsidised insulin or CGM, PMI is the wrong product — the NHS remains the right answer. PMI adds value for the acute events that diabetics are statistically more likely to face.

Common questions

Can I get health insurance if I have diabetes?

Yes. All seven major UK PMI insurers will insure diabetics. The diabetes itself and its direct maintenance is excluded, but unrelated conditions are covered fully. WPA and The Exeter offer the most flexible individualised underwriting for diabetics.

Does PMI cover insulin, CGM or diabetic supplies?

No — routine diabetes maintenance (insulin, glucose monitors, HbA1c testing, dietician appointments for maintenance) is not what PMI is designed to fund. This remains an NHS service. PMI covers acute treatment for conditions the NHS is slow or overloaded on.

What is the '2-year moratorium rule' for diabetics?

Moratorium underwriting excludes any condition you have had symptoms of, treatment for or medication for in the last 5 years. Once you have been symptom-free, treatment-free and medication-free for 2 continuous years on your PMI, that condition returns to cover. For type 2 diabetes reversed by diet and exercise, this can be extremely valuable.

Are diabetic complications covered by PMI?

It depends. Cardiac events, retinopathy, neuropathy and kidney disease can be covered under moratorium after the 24-month rule, or considered under tailored FMU by The Exeter or WPA. Full Medical Underwriting typically excludes them permanently if diabetes has been declared.

Which UK insurer is best for diabetics?

WPA Flexible Health and The Exeter Health+ are the two insurers with the most sophisticated individualised underwriting for diabetic applicants. For younger, well-controlled type 2 diabetics, Bupa or AXA moratorium can also work at competitive pricing.

Is type 1 diabetes coverable?

Type 1 will effectively always be excluded on PMI — it cannot satisfy the 24-month symptom-free rule. However, the policy still provides valuable cover for unrelated conditions. The Exeter Health+ is the insurer most likely to consider individualised terms for type 1.

Will I pay a higher premium if I'm diabetic?

Not necessarily. With diabetes excluded, the insurer's risk on unrelated conditions is unchanged, so premium is often the same as a non-diabetic. Some insurers may load 5–15% for FMU applicants with type 2; The Exeter and WPA typically do not.

Can I claim on PMI for gestational diabetes?

Gestational diabetes itself is not covered (routine pregnancy is excluded on almost all UK PMI). However, complications requiring urgent hospital treatment can be covered on a policy with maternity add-ons — always check the policy schedule.
