Applying for life insurance can feel like a daunting prospect, and if you're carrying a few extra pounds, you might worry about how your weight will affect your application. It's a common concern. According to the latest NHS Health Survey for England, an estimated 64% of adults are classified as overweight or living with obesity. The good news? Having a high Body Mass Index (BMI) doesn't automatically disqualify you from getting the vital protection you and your family need.
Insurers are in the business of risk, and while weight is a significant factor in their calculations, it's just one piece of a much larger puzzle. They are interested in your overall health profile. An active person with a higher BMI may well secure better terms than a sedentary individual with a 'healthy' BMI who smokes.
This comprehensive guide is designed to demystify the process. We'll explore exactly what you need to disclose about your weight and health, how insurers assess this information, and the practical steps you can take to secure the best possible cover at the most competitive price. With the right knowledge and expert guidance, you can navigate the application process with confidence.
When you apply for life insurance, critical illness cover, or income protection, the insurer needs to build a clear picture of your health to accurately calculate the risk and, consequently, your premium. Honesty and accuracy are paramount; failing to disclose information can have serious consequences, potentially leading to a claim being denied when your family needs it most.
Here’s a breakdown of the key information you’ll need to provide and why it matters.
This is the starting point for almost every insurer. They use your height and weight to calculate your Body Mass Index (BMI).
What is BMI? BMI is a simple calculation that uses your height and weight to work out if you are a healthy weight. The formula is your weight in kilograms divided by the square of your height in metres (kg/m²).
Why it matters: While not a perfect measure of health (it doesn't distinguish between fat and muscle), BMI is a standardised, universal tool that gives insurers an initial indication of potential health risks. A higher BMI is statistically linked to an increased risk of developing conditions like heart disease, stroke, type 2 diabetes, and certain cancers.
How it affects premiums: Based on your BMI, an insurer will place you into a category. This can range from 'standard rates' (no price increase) to a 'loading' (a percentage increase on the standard premium), or in some cases, a postponement or decline.
Increasingly, insurers are asking for waist measurements in addition to BMI, particularly for those with a higher BMI.
Why it matters: Your waist measurement is a strong indicator of visceral fat – the harmful fat stored around your vital organs in your abdomen. High levels of visceral fat significantly increase the risk of cardiovascular disease and type 2 diabetes, sometimes even more so than a high BMI alone.
How it's measured: Insurers typically want a measurement taken from the midpoint between the bottom of your ribs and the top of your hips.
How it affects premiums: A large waist measurement, even with a moderately high BMI, can signal a higher risk to the insurer and may result in a higher premium loading than your BMI alone would suggest.
Insurers will likely ask if your weight has changed significantly in the last 12 months.
This is perhaps the most crucial part of your disclosure. A high BMI on its own might result in a small premium increase, but a high BMI combined with a related medical condition will have a much bigger impact. You must disclose:
Full transparency here allows the underwriter to make a fair and accurate assessment.
Your daily habits provide vital context to your application.
Being upfront about all these factors is not just a requirement; it’s your best strategy. It allows a specialist broker, like us at WeCovr, to present your case to the most suitable insurer in the best possible light.
Once you've submitted your application, it goes to an underwriter. Their job is to evaluate the level of risk you present based on the information provided. Let's pull back the curtain on how they typically approach an application from someone who is overweight.
Underwriting is the foundation of the insurance industry. An underwriter assesses your life expectancy and health risks against statistical data. For life insurance, the key question is: "What is the likelihood of this person passing away during the term of the policy?" For critical illness or income protection, it's: "What is the likelihood of this person suffering a serious illness or being unable to work?"
Your BMI is an immediate flag that helps them categorise your application. It acts as a gateway to a more detailed investigation of your overall health.
While every insurer has its own specific underwriting guidelines, they generally follow a similar pattern. The table below provides a typical (but not guaranteed) overview of how an insurer might respond to different BMI levels for an applicant with no other disclosed medical conditions.
| BMI Range | Classification | Likely Insurer Response |
|---|---|---|
| 18.5 - 24.9 | Healthy Weight | Standard Rates: The best possible premium with no price increases. |
| 25.0 - 29.9 | Overweight | Standard Rates: Most applicants in this range can still secure standard terms. |
| 30.0 - 34.9 | Obesity Class I | Small Loading: A premium increase of +25% to +50% is common. |
| 35.0 - 39.9 | Obesity Class II | Moderate to High Loading: A premium increase of +75% to +150% is possible. |
| 40.0+ | Obesity Class III | High Loading or Postponement: A loading of +150% or more, or the insurer may postpone the decision. |
| 45.0+ | Morbid Obesity | Postponement or Decline: It becomes very difficult to find cover. Insurers may postpone for 12 months pending significant weight loss. |
What is a 'Loading'?
A loading, or 'rating', is a percentage increase on the standard base premium. For example, if the standard monthly premium for a policy is £20 and you receive a +50% loading, your final premium will be £30 per month. This reflects the increased risk the insurer is taking on.
It's crucial to remember that the table above is a simplified guide. Underwriters are trained to look at the complete picture.
Muscle vs. Fat: A classic example is a professional rugby player or bodybuilder. They may have a BMI of 32, placing them in the 'Obesity Class I' category. However, their high weight is due to muscle mass, not excess body fat. Their body fat percentage is low, and they are exceptionally fit. A good insurance broker can provide this context, along with evidence like body fat measurements or fitness test results, to argue for standard rates.
The "Otherwise Healthy" Factor: An applicant with a BMI of 33 who doesn't smoke, drinks moderately, exercises three times a week, and has perfect blood pressure and cholesterol readings is a much better risk than an applicant with a BMI of 28 who smokes 10 cigarettes a day and has borderline high blood pressure. The underwriter will take all these positive factors into account.
Age Matters: A 30-year-old with a high BMI has more time to develop weight-related conditions than a 55-year-old applying for a 15-year policy. The risk profile changes with age, and this is factored into the final decision.
The key takeaway is that your BMI opens the door to a conversation. It's the subsequent details about your health, lifestyle, and any associated conditions that will ultimately determine the outcome of your application.
While a high BMI can lead to a premium loading, it's the presence of associated medical conditions that will most significantly influence an underwriter's decision. If your weight has contributed to or worsened other health issues, insurers will scrutinise these very closely.
Let's examine the most common conditions and what insurers want to know.
Often called the "silent killer" because it has no obvious symptoms, hypertension is strongly linked to excess weight. It puts extra strain on your heart and arteries, increasing the risk of heart attacks and strokes.
What insurers will ask:
Impact on Premiums: Well-controlled hypertension, with good recent readings and minimal medication, might only add a small loading (+25% to +50%) on top of any BMI-related increase. Uncontrolled or recently diagnosed high blood pressure will result in a much higher loading or a postponement until it is stable.
Excess weight, particularly with a diet high in saturated fats, can lead to high levels of 'bad' (LDL) cholesterol in your blood. This can lead to the furring and hardening of your arteries (atherosclerosis).
What insurers will ask:
Impact on Premiums: If your cholesterol is managed effectively with statins and your overall cholesterol ratio is good, the impact may be minimal. However, very high readings, especially when combined with other risk factors like smoking or high blood pressure, will be viewed more seriously.
Type 2 diabetes is one of the most significant health concerns linked to being overweight. It affects how your body processes sugar and, if not managed well, can lead to severe complications affecting your eyes, nerves, kidneys, and heart.
What insurers will ask:
Impact on Premiums: This can vary hugely. A recently diagnosed, diet-controlled individual with an excellent HbA1c reading might see a loading of +75% to +100%. An applicant on insulin with a long-standing diagnosis and a high HbA1c reading could face a much higher loading (+150% or more) or even a decline, especially for critical illness cover.
OSA is a condition where your breathing repeatedly stops and starts during sleep. It is very common in people who are overweight, as excess tissue around the neck can obstruct the airway.
What insurers will ask:
Impact on Premiums: Undiagnosed or untreated sleep apnoea is a major red flag for insurers due to its link to daytime sleepiness (increasing accident risk) and heart problems. However, an applicant who has been diagnosed and is successfully using a CPAP machine will be viewed far more favourably and may only receive a small loading.
Knowing that your weight and health are under the microscope can be intimidating, but there's a lot you can do to strengthen your application and secure better terms. Taking proactive steps not only improves your chances with insurers but also benefits your long-term health and wellbeing.
It can be tempting to think, "I'll apply once I've lost weight." While well-intentioned, this can be a risky strategy. Life insurance is always cheapest when you are younger and healthier. By waiting, you risk:
It is often better to secure cover now, even if it comes with a loading. You can always review and potentially replace the policy with a cheaper one in the future if your health and weight improve significantly.
If you are carrying excess weight, making a commitment to lose it is the single most effective thing you can do. But it's how you do it that matters to insurers.

Being prepared makes the application process smoother and faster. Before you start, gather the following:
Having this information to hand shows you are organised and engaged with your health.
When your application is straightforward, using a comparison website might seem easy. But when there are complexities like a high BMI or related health conditions, going it alone can be a costly mistake. This is where a specialist independent broker becomes your most valuable asset.
Market Knowledge: The UK insurance market is vast. Every insurer has a different "appetite for risk" and unique underwriting rules. Some are notoriously strict about BMI, while others are more lenient. Some might be tough on diabetes but more relaxed about blood pressure. A broker knows these nuances inside out. We know which door to knock on first for your specific circumstances.
No "Footprint": Applying directly to an insurer and getting a high rating or a decline leaves a digital footprint. Future insurers may ask if you've ever been declined or offered special terms before. A broker can make anonymous, informal enquiries on your behalf to test the waters without leaving any mark on your record.
Framing Your Application: We don't just fill in a form. We build your case. We can add a cover letter to your application explaining the context – for example, that your high BMI is due to muscle, or that you've recently transformed your lifestyle and have the data to prove it. This personal touch can make the difference between a standard rate and a heavy loading.
Fighting Your Corner: If an insurer comes back with an unfair decision, we will challenge it. We can provide further evidence from your GP or argue your case with the underwriting team to get you a better outcome. We work for you, not the insurer.
At WeCovr, we specialise in helping people with complex health histories find the right protection. We have extensive experience in securing life insurance, critical illness cover, and income protection for clients who are overweight or have related medical conditions.
Our process is simple and client-focused:
Using a specialist broker doesn't cost you more – in fact, our expertise will almost certainly save you money by finding you the most competitive premium available.
While life insurance is a common starting point, it's important to consider what you're trying to protect against. There are several types of cover, each designed for a different purpose. Your weight and health will affect your eligibility and premiums for all of them.
This pays out a lump sum if you pass away during the policy term. It’s designed to clear debts like a mortgage and provide for your family’s future.
A more affordable and often overlooked alternative to a lump-sum life insurance policy.
This pays out a tax-free lump sum if you are diagnosed with one of a list of specific, serious illnesses defined in the policy (e.g., heart attack, stroke, most cancers).
Often described by experts as the most important protection policy of all. It acts as a replacement for your salary if you are unable to work due to any illness or injury.
If you run your own business or work for yourself, the need for a robust financial safety net is even more acute. Your personal health is directly linked to the health of your business.
When you're self-employed, there's no employer to provide sick pay or death-in-service benefits. If you can't work, your income stops.
Your BMI and health will be assessed in the same way as for a personal application, but securing this cover is vital to protect your livelihood.
Beyond your personal needs, you should consider how your health impacts the business itself. There are tax-efficient ways to arrange protection through your limited company.
Key Person Insurance: What would happen to your business if you, or another crucial employee, were to die or become critically ill? Could the business survive the loss of revenue, repay loans, or recruit a replacement? Key Person Insurance is a policy taken out and paid for by the business on the life of a key individual. The payout goes to the business to help it weather the storm. The premiums are based on the health of the key person, including their BMI.
Relevant Life Cover: This is a tax-efficient death-in-service policy for individual employees or directors. The company pays the premium, but the payout goes directly to the employee's family, free of inheritance tax. The premiums are typically an allowable business expense, and it's not treated as a P11D benefit-in-kind for the employee. It's an excellent way for small businesses to offer attractive employee benefits.
Executive Income Protection: Similar to Relevant Life Cover, this is an income protection policy paid for by the company for a director or employee. It's a tax-efficient way to provide a long-term sick pay benefit, with premiums usually qualifying as a business expense.
For all these business protection policies, the health and lifestyle of the individual being insured – including their weight – is the basis for the underwriting and the final premium.
To illustrate how the factors we've discussed come together, let's look at some anonymised case studies. These are based on typical underwriting outcomes for a 40-year-old non-smoker seeking £250,000 of level term life insurance over 25 years, with a standard base premium of £25 per month.
| Case Study | BMI | Key Health Factors | Likely Outcome | Estimated Premium |
|---|---|---|---|---|
| Sarah | 32 | Otherwise healthy, exercises regularly, good diet. | +50% Loading: A small increase for the BMI. | £37.50 / month |
| David | 36 | Controlled high blood pressure (on one medication). | +100% Loading: A combined rating for BMI and BP. | £50.00 / month |
| Emily | 41 | Type 2 diabetes (tablet-controlled, HbA1c of 8.5%). | +200% Loading or Postponement: The high BMI and poor diabetic control is a major concern. | £75.00+ / month |
| Mark | 31 | Bodybuilder, low body fat %, excellent fitness. | Standard Rates: Broker provided evidence to show BMI was not indicative of risk. | £25.00 / month |
These examples clearly show that while BMI sets a baseline, it's the combination of all health and lifestyle factors that dictates the final premium. It also highlights the value a broker can bring, as seen in Mark's case, by providing context that a simple online form cannot.
Navigating the world of life insurance when you're overweight can seem complex, but it is far from impossible. The key takeaways to remember are:
Being overweight is a reality for a majority of UK adults. It should not be a barrier to securing the peace of mind that comes from knowing your family and finances are protected. By understanding the process and taking the right approach, you can get the cover you need and deserve.
