Can You Get Life Insurance With Type 2 Diabetes in the UK?

Yes — and in 2026 it is more accessible than many people with type 2 diabetes realise. Around 90% of people with diabetes in the UK have type 2, which means UK insurers underwrite this condition routinely and have well-developed processes for assessing applications. The majority of applicants with well-controlled type 2 diabetes can secure life insurance, typically with a premium loading rather than an outright decline.

The key factors that determine your outcome are your HbA1c level (the measure of blood glucose control over the past 2-3 months), whether you have any diabetes-related complications, your BMI, your smoking status, and how long you have had the diagnosis. Understanding how each of these factors affects your application gives you the best chance of securing competitive cover.

How HbA1c Affects Your Life Insurance Premium

Your HbA1c reading is the single most important factor in your life insurance application as a type 2 diabetic. It tells underwriters how well your blood glucose has been controlled over the past two to three months. Here is how different HbA1c levels typically affect your premium loading in 2026:

A 40-year-old non-smoker with well-controlled type 2 diabetes (HbA1c around 50, no complications) might pay approximately £20-30 per month for £200,000 of level term cover over 20 years, compared with £15-20 for a standard applicant without diabetes. Poor control (HbA1c 75+) or complications could push this to £40-60 or more per month, or result in a postponement while control improves.

What Information Do Insurers Ask For?

When you apply for life insurance with type 2 diabetes, expect to provide:

• The type of diabetes (Type 1 or Type 2) and date of diagnosis
• Your most recent HbA1c reading and date it was taken
• How you manage your diabetes — diet and lifestyle only, oral medication (metformin, etc.), or insulin injections
• Any diabetes-related complications: retinopathy (eye disease), neuropathy (nerve damage), nephropathy (kidney disease), or cardiovascular complications
• Your BMI (height and weight)
• Smoking status
• Blood pressure readings
• Any other medical conditions or medications

Have this information ready before starting your application — it speeds up the process significantly and reduces the chance of your application being delayed for a GP report.

Complications and How They Affect Underwriting

Type 2 diabetes without complications is assessed very differently from type 2 diabetes with established complications. The most significant complications from an underwriting perspective are:

Retinopathy (diabetic eye disease): A common complication that is noted by underwriters. Background retinopathy with no impact on vision adds a moderate loading. More advanced retinopathy significantly increases the premium or may result in a decline from some insurers.

Neuropathy (nerve damage): Peripheral neuropathy adds a significant loading — typically 75-150% above standard rates. Severe or autonomic neuropathy results in higher loadings or potential decline.

Nephropathy (kidney disease): Diabetic kidney disease is the most serious complication from a life insurance underwriting perspective. Even mild nephropathy adds substantial loadings — 100-200% or more above standard. Advanced kidney disease may result in decline from mainstream insurers, though specialist impaired risk underwriters may still offer cover.

Cardiovascular disease: A previous heart attack, angina, or other cardiovascular complication in the context of diabetes is assessed separately as a combined risk. The combined loading for diabetes and cardiovascular disease is higher than either condition alone.

If you have complications, using a specialist broker who knows which insurers take the most favourable view of your specific combination of factors is essential. Premium differences between insurers for complex diabetic applications can be very significant.

Type 1 vs Type 2 — The Underwriting Difference

Type 2 diabetes is generally viewed as lower risk than Type 1 by UK life insurance underwriters for several reasons: it is typically diagnosed in adulthood (so complications have had less time to develop); it can sometimes be managed through lifestyle changes alone; and in some cases, it can be put into remission through weight loss and diet.

Type 1 diabetes — an autoimmune condition present from childhood or young adulthood — is lifelong and requires insulin management. The longer duration of condition, lifelong insulin dependency, and higher statistical risk of complications means Type 1 applicants typically face higher premium loadings than Type 2 applicants with equivalent control levels. However, Type 1 applicants with excellent HbA1c control and no complications can still secure life insurance at competitive rates through specialist underwriters.

Tips to Improve Your Application and Reduce Your Premium

1. Improve your HbA1c before applying. Even a small reduction in HbA1c can shift you into a lower loading band. If your recent reading is above 58 mmol/mol, speak to your GP or diabetes nurse about optimising your management before submitting an insurance application.
2. Stop smoking. Smoking combined with diabetes dramatically increases cardiovascular risk and has the biggest single impact on your premium loading. Most insurers require 12 months nicotine-free before offering non-smoker rates.
3. Manage your weight. A high BMI adds a separate loading on top of the diabetes loading. Reducing your BMI towards a healthy range (18.5-24.9) before applying improves your underwriting profile.
4. Attend all diabetes reviews. Demonstrating regular monitoring and good engagement with your diabetes care team signals to underwriters that you are actively managing your condition.
5. Use a specialist broker. Mainstream comparison sites are designed for standard applications. A specialist impaired risk broker knows which of the 50+ UK insurers takes the most favourable view of type 2 diabetic applications — this knowledge can save you hundreds of pounds per year.
6. Apply for the cover you actually need. Paying inflated premiums for unnecessarily high sum assured increases the cost without benefit. Calculate your genuine need and apply for that amount only.

Which UK Life Insurers Are Best for Type 2 Diabetics?

Underwriting criteria for diabetes vary between providers and change regularly. Some insurers are consistently more competitive for well-controlled type 2 diabetics; others take a more favourable view of complex cases with complications. Because this changes frequently and depends on your specific profile, the most reliable approach is to use a specialist broker who can pre-underwrite your application with multiple insurers before you formally apply.

Major UK providers that routinely underwrite type 2 diabetes include Legal & General, Aviva, Royal London, LV=, and Scottish Widows. Specialist impaired risk providers — including Exeter Family Friendly and some Lloyd's of London-backed providers — may offer more competitive terms for complex or poorly controlled cases.

Crucially, a formal application creates a record with that insurer. Using a broker to pre-underwrite your application anonymously avoids multiple formal declines or postponements appearing on your insurance history, which can make subsequent applications more difficult.

Can I Get Critical Illness Cover With Type 2 Diabetes?

Critical illness cover with type 2 diabetes is possible but typically includes exclusions for diabetes-related conditions. A policy might pay out for an unrelated cancer diagnosis but exclude claims for conditions that are statistically linked to diabetes — such as certain heart conditions, kidney failure, or stroke — where the diabetes is considered a contributing factor.

The specific exclusions vary between providers. Some insurers are more generous in their critical illness cover for diabetics than others. A specialist broker can identify which providers offer the broadest critical illness cover with the fewest diabetes-related exclusions for your specific health profile.

Frequently Asked Questions

Will I definitely be declined for life insurance with type 2 diabetes?

No. Most people with type 2 diabetes can get life insurance. Well-controlled type 2 diabetes with no complications is routinely accepted, typically with a premium loading of 25-75% above standard rates. Even poorly controlled diabetes or diabetes with complications may be insurable through specialist providers, though loadings will be higher.

How much more will I pay for life insurance with type 2 diabetes?

For well-controlled type 2 diabetes (HbA1c under 58 mmol/mol, no complications), expect a loading of 25-50% above standard rates. A 40-year-old non-smoker might pay around £20-30 per month for £200,000 of 20-year level term cover versus £15-20 without diabetes. Poor control or complications increase this significantly.

Can diet-controlled type 2 diabetes get standard rates?

Possibly. If your type 2 diabetes is managed entirely through diet and lifestyle, with a recent HbA1c under 48 mmol/mol and no complications, some insurers may offer near-standard or mildly loaded rates. This is the best-case underwriting scenario for type 2 diabetics. Always compare multiple providers as criteria vary.

What is HbA1c and why does it matter?

HbA1c (glycated haemoglobin) is a blood test that measures your average blood glucose level over the past 2-3 months. It is the standard measure of diabetes control used by both healthcare professionals and insurance underwriters. A lower, stable HbA1c indicates better control and typically results in more favourable insurance terms.

Should I use a comparison site or a specialist broker?

For type 2 diabetes, a specialist impaired risk broker is strongly recommended over standard comparison sites. Comparison sites typically cannot accommodate the medical questions required for a diabetic application and may not access the specialist underwriters that offer the most competitive diabetic rates. A broker can also pre-underwrite your application to avoid formal declines.

Conclusion

Life insurance with type 2 diabetes in the UK is widely available and, for well-controlled diabetes without complications, can be secured at competitive rates. The keys are maintaining good HbA1c control, avoiding smoking, managing your weight, and using a specialist whole-of-market broker who understands diabetic underwriting.

Do not be deterred by a previous decline or a high quote from one provider — underwriting criteria vary significantly between insurers, and the right broker will identify the most favourable insurer for your specific profile. For impartial guidance, visit MoneyHelper.
