Most Type 2 diabetics on metformin or sulphonylureas assume the underwriting story is identical to someone on insulin. It isn't. Tablets-only diabetes with a controlled HbA1c is a materially different risk profile in the eyes of most underwriters — and that difference can mean a loading of 12% instead of 40%, or an offer instead of a decline.

The gap isn't guaranteed, and it narrows as the condition gets more complex. But if you're on tablets and you've been quoted a loading that feels too high, it's worth understanding what's driving it — and what can be done about it.

What's actually different on tablets

In underwriting mental models, tablets versus insulin is a rough proxy for severity. Tablets-only usually signals earlier or more stable disease; insulin usually signals that the pancreas is producing insufficient insulin or that oral medications aren't controlling glucose well enough. That proxy is imprecise — a tablet-managed HbA1c of 9.5 is riskier than a well-controlled insulin case at 7.2 — but it shapes the initial read of the file.

The practical consequence: for tablets-only diabetes with an HbA1c below 7.5 and no recorded complications, most standard insurers will issue a policy. The loading is typically in the range of 10–20% above the standard premium. For multiple tablets with an HbA1c above 8, the picture starts to look more like insulin underwriting — loading in the 20–35% range, and some insurers becoming reluctant.

Who will write you cleanly

“Cleanly” is relative — for diabetes, a small loading is the norm rather than the exception. What you're looking for is a reasonable loading, a realistic waiting period, and no carved-out sub-limits that gut the policy's value for exactly the complications you're at risk of.

The insurers who write tablets-only diabetes well are the ones whose underwriting teams actually read the file rather than running it through a rule-based algorithm. Which companies are doing that at any given time changes — the market moves. What doesn't change is that a structured proposal with complete documentation consistently outperforms a direct online application for anything with a pre-existing condition.

When the difference matters less than you think

There is one thing that is identical whether you're on tablets or insulin: declaration discipline. The form will ask if you take any medication for diabetes. You tick yes. The name of the tablet, the dose, the duration — all of it goes into the proposal. Not because the insurer is looking for a reason to decline you, but because a future claims processor who finds undisclosed medication in your pharmacy record has grounds to repudiate the claim.

This is the number one reason health insurance claims get rejected for diabetics — not the condition itself, but an incomplete declaration at the time of application. The loading you avoided by hiding the tablets is never worth the claim you lose when the insurer investigates the hospitalisation record and finds the prescription trail.

Declare everything. Get the loading you actually deserve, not a false clean bill of health that will come apart under scrutiny.
