Private health insurance for diabetics in the UK
You can take out private medical insurance if you have type 1 or type 2 diabetes — most UK insurers will offer a policy. But insurers class diabetes as a chronic, pre-existing condition, so the diabetes itself is generally excluded from cover. What you are really buying is faster private access for everything else. Here is how it works in practice.
The essentials in 30 seconds
- Yes, you can get PMI with diabetes: most UK insurers will offer a policy to people with type 1 or type 2 diabetes — having the condition does not stop you taking out cover.
- The diabetes itself is generally excluded: insurers treat diabetes as a chronic condition, so its routine management — reviews, medication, monitoring — is not what PMI is designed to pay for.
- New, unrelated conditions are covered: a policy can still pay for private diagnostics, specialist appointments and treatment for acute conditions that have nothing to do with your diabetes.
- Your NHS diabetes care continues unchanged: GP reviews, prescriptions and annual checks stay exactly as they are — PMI sits alongside the NHS, it does not replace it.
What PMI typically covers and excludes when you have diabetes
| Situation | How PMI typically treats it |
|---|---|
| Routine diabetes management (reviews, medication, HbA1c and glucose monitoring) | Generally excluded — ongoing management of a chronic condition sits with the NHS, not PMI. |
| Complications arising from diabetes (for example retinopathy, neuropathy or foot problems) | Usually treated as related to the diabetes and excluded, though exact wording varies between insurers. |
| An acute flare-up of a chronic condition | Varies — some policies help with treatment to stabilise an acute episode before care passes back to the NHS. Check the policy wording. |
| A new condition unrelated to diabetes (for example a knee injury, a hernia or gallstones) | Typically covered in line with the policy terms, exactly as it would be for someone without diabetes. |
| Private diagnostics for new, unrelated symptoms | Typically covered — fast access to scans and specialist opinion is one of the main reasons people buy PMI. |
| Emergency care | Not what PMI is for — accident and emergency treatment remains with the NHS regardless of your policy. |

How underwriting treats diabetes
Under a moratorium, recent conditions are excluded automatically without you declaring your history. A parked condition can normally become eligible again after a continuous period — commonly around two years — free of symptoms, treatment, medication and medical advice. Diabetes rarely passes that test: because it involves ongoing medication, monitoring and reviews, the exclusion effectively stays in place for as long as the condition is being managed.
Under full medical underwriting (FMU), you declare your diabetes when you apply and the insurer names its exclusions up front — typically the diabetes and conditions arising from it. The advantage is certainty: you know from day one exactly where you stand. The mechanics of both routes are covered in moratorium vs full medical underwriting, and private health insurance and pre-existing conditions explains what insurers count as pre-existing in the first place.
Why people with diabetes still take out PMI
More than 5.6 million people in the UK are living with diabetes, according to Diabetes UK — around nine in ten of them with type 2. Insurers deal with applications from people with diabetes every day, and a diagnosis does not shut you out of the private system. What changes is the shape of the cover: the policy protects you against the cost and waiting times of everything other than your diabetes — private consultations, diagnostics and treatment for new conditions, often within days rather than months.
Two things are worth knowing. First, always answer any application questions honestly — non-disclosure is a common reason claims are declined. Second, if your type 2 diabetes has gone into remission, insurers vary in how they treat it: many will still regard it as pre-existing, though some may review an exclusion after a settled period, so it is worth asking before you apply.
