Insurance Curator 
If you’re living with diabetes, you might assume life insurance is out of reach or prohibitively expensive. That’s simply not true. Thousands of people with Type 1 and Type 2 diabetes secure affordable cover every year across the UK. The secret lies in understanding the underwriting process.
Insurers don’t see a diabetes diagnosis as an automatic decline. They look at how well you manage your condition, your overall health, and any complications. The difference between Type 1 and Type 2 diabetes can significantly impact your premiums and the terms offered. This guide breaks down exactly what insurers consider, so you can approach your application with confidence.

Understanding Diabetes Underwriting
Underwriting is the process insurers use to assess risk. For diabetes, they want to know:
- Type of diabetes (Type 1 vs Type 2)
- Age at diagnosis
- Current HbA1c levels (average blood sugar over 2–3 months)
- Any complications (retinopathy, kidney issues, neuropathy)
- Lifestyle factors (smoking, BMI, diet, exercise)
- Medication (insulin dependence vs oral medication)
Insurers in the UK typically request a report from your GP and may ask for a recent blood test. The better your control and the lower your risk of complications, the more favourable your premium will be.
Type 1 Diabetes: What Insurers Look For
Type 1 diabetes is an autoimmune condition usually diagnosed in childhood or early adulthood. Because it requires lifelong insulin therapy, insurers view it as a higher risk than well-controlled Type 2.
Key underwriting factors for Type 1:
- HbA1c level: Under 58 mmol/mol (7.5%) is generally considered good control. Levels above 75 mmol/mol may lead to higher loadings or even declinature.
- Duration of condition: A longer history with good control can work in your favour, as it shows stability.
- Complications: Evidence of retinopathy, nephropathy, or cardiovascular issues will result in higher premiums or exclusions.
- Insulin management: Use of insulin pumps or continuous glucose monitors (CGMs) can demonstrate proactive management.
Most insurers will offer standard or slightly loaded rates for well-controlled Type 1 diabetes. However, some providers specialise in diabetes cover and may be more competitive.
Type 2 Diabetes: A Different Risk Profile
Type 2 diabetes is often linked to lifestyle factors, and many people manage it with diet, exercise, and oral medication. This generally results in lower premiums compared to Type 1, especially if your condition is well controlled.
Key underwriting factors for Type 2:
- HbA1c level: Below 48 mmol/mol (6.5%) is excellent. Between 48–58 mmol/mol is acceptable with some loading. Above 64 mmol/mol may require specialist cover.
- Medication: Diet-controlled Type 2 is viewed most favourably. Metformin alone is fine, but insulin or multiple oral medications indicate progression.
- BMI: Obesity (BMI over 30) combined with Type 2 can cause significant loading or declinature.
- Age at diagnosis: Diagnosed later in life (e.g., after 50) often carries lower risk than early-onset Type 2.
Many high-street insurers offer standard rates for well-controlled Type 2 diabetes. A small number of providers even offer standard rates without a GP report if your HbA1c and other metrics meet their criteria.
Key Underwriting Factors for Both Types
The table below summarises how different factors influence underwriting decisions for diabetes.
| Factor | Favourable Range | Unfavourable Range |
|---|---|---|
| HbA1c | Under 58 mmol/mol (7.5%) | Over 75 mmol/mol (9%) |
| Duration | Over 5 years with good control | Recent diagnosis with limited data |
| Complications | None | Retinopathy, kidney disease |
| Smoking | Non-smoker | Smoker (doubles risk) |
| BMI | 18.5–27 | Over 35 |
| Medication | Diet or oral only | Insulin or multiple drugs |
| Blood pressure | Under 140/90 | Uncontrolled hypertension |
| Cholesterol | Under 5 mmol/L | Over 7 mmol/L |
How to Improve Your Chances of Acceptance
You’re not powerless. Taking simple steps before you apply can make a big difference.
- Optimise your HbA1c: Aim for a reading under 58 mmol/mol. Work with your GP or diabetes specialist.
- Lose weight: Even a 5% reduction in body weight can improve insulin sensitivity and lower premiums.
- Stop smoking: This is the single biggest factor. Non-smokers with diabetes pay far less.
- Check your blood pressure and cholesterol: Get them under control with medication if needed.
- Gather your records: Ask your GP for a summary of your diabetes history and recent test results.
If you have existing complications, don’t panic. Some insurers will still offer cover with exclusions for those specific conditions. For example, they might cover you for life insurance but exclude death due to diabetic complications. Always compare multiple providers.
The Role of Specialist Brokers
Navigating diabetes underwriting alone can be overwhelming. Specialist life insurance brokers for pre-existing conditions know which insurers are most lenient for different types of diabetes. They can:
- Advise on which provider is likely to give the best terms
- Help you prepare your GP report
- Appeal if you receive a higher premium than expected
- Access panels of insurers you might not find online
If you’re declined for life insurance, don’t give up. There are alternative products like guaranteed acceptance life cover (no medical questions) or over-50s plans that accept all applicants regardless of health.

Final Thoughts
Having diabetes does not mean you have to go without life insurance. The key is to understand how underwriters view your specific condition and to take proactive steps to improve your risk profile. Type 2 diabetes typically offers more flexibility and lower premiums, but well-controlled Type 1 can also secure standard rates with the right provider.
Always work with a specialist broker if your case is complex, and never withhold medical information—that can void your policy later. With the right preparation, you can protect your family’s financial future regardless of your diabetes type.
