This guide provides a critical analysis for HR Directors considering one of the most talked-about employee benefits: prescription weight-loss medication like Wegovy. A cost-benefit analysis for HR Directors.
Key takeaways
- Prevalence: Approximately 1 in 4 adults in the UK are living with obesity. Within a typical workforce, this means a significant portion of your employees may be struggling with their health.
- Absenteeism: A 2023 report highlighted that individuals with obesity take an average of four extra sick days per year compared to those with a healthy weight.
- Related Conditions: Obesity is a primary driver of numerous chronic and acute health problems, including Type 2 diabetes, cardiovascular disease, hypertension, and musculoskeletal issues (e.g., back and knee pain). These are leading causes of employee absence.
- Presenteeism: Beyond sick days, there's the hidden cost of 'presenteeism'—when employees are at work but are less productive due to ill health, fatigue, or discomfort. Research suggests the cost of presenteeism can be several times higher than that of absenteeism.
- It mimics a natural hormone: It copies the action of a gut hormone that is released after eating.

A cost-benefit analysis for HR Directors. Comparing Bupa's Weight Management add-on vs. the cost of obesity-related sick leave in the UK workforce
The health of your workforce is the bedrock of your organisation's success. Yet, UK businesses face a growing and costly challenge: the impact of obesity on employee health, attendance, and productivity. As we look towards 2026, a new generation of clinically-proven weight management treatments, most notably Wegovy (semaglutide), is entering the corporate benefits arena.
This presents a pivotal question for strategic HR and leadership teams: Should your company pay for staff to access these treatments through your corporate health insurance?
This definitive guide provides a clear cost-benefit analysis. We will weigh the direct cost of enhanced private medical insurance (PMI) against the significant, often hidden, costs of obesity-related sick leave and reduced productivity. We will dissect Bupa's pioneering Weight Management pathway as a prime example and equip you with the data needed to build a compelling business case.
The Staggering Cost of Obesity to UK Businesses
To make an informed decision, you must first grasp the scale of the problem. The financial drain of obesity on UK plc is not a vague wellness concept; it is a measurable economic reality.
According to recent data from sources like the NHS and the Office for National Statistics (ONS), the situation is stark:
- Prevalence: Approximately 1 in 4 adults in the UK are living with obesity. Within a typical workforce, this means a significant portion of your employees may be struggling with their health.
- Absenteeism: A 2023 report highlighted that individuals with obesity take an average of four extra sick days per year compared to those with a healthy weight.
- Related Conditions: Obesity is a primary driver of numerous chronic and acute health problems, including Type 2 diabetes, cardiovascular disease, hypertension, and musculoskeletal issues (e.g., back and knee pain). These are leading causes of employee absence.
- Presenteeism: Beyond sick days, there's the hidden cost of 'presenteeism'—when employees are at work but are less productive due to ill health, fatigue, or discomfort. Research suggests the cost of presenteeism can be several times higher than that of absenteeism.
Let's translate this into tangible figures for your business. The average cost of a sick day per employee in the UK is estimated to be around £150-£200 when considering lost output, management time, and temporary cover.
| Company Size (Employees) | Estimated Employees with Obesity (at 25%) | Extra Annual Sick Days (4 per employee) | Estimated Annual Cost of Absenteeism (at £175/day) |
|---|---|---|---|
| 50 | 13 | 52 | £9,100 |
| 250 | 63 | 252 | £44,100 |
| 1,000 | 250 | 1,000 | £175,000 |
Insider Tip: These figures are conservative. They do not account for the increased risk of long-term disability, the impact on team morale when colleagues are frequently absent, or the hidden productivity losses from presenteeism. The true cost to your organisation is likely much higher.
What is Wegovy and How Does It Work?
Before analysing its role in a benefits package, it's crucial to understand what Wegovy is and, equally, what it isn't.
Wegovy is the brand name for semaglutide, a prescription-only injectable medication. It belongs to a class of drugs called GLP-1 receptor agonists. In simple terms:
- It mimics a natural hormone: It copies the action of a gut hormone that is released after eating.
- It regulates appetite: This hormone targets areas of the brain that control hunger, making you feel fuller for longer and reducing cravings.
- It slows digestion: It also slows down the rate at which your stomach empties, contributing to the feeling of satiety.
Key Facts for HR Directors:
- It's a Clinical Treatment: This is not a cosmetic or lifestyle drug. It is a medically supervised treatment for individuals clinically diagnosed with obesity.
- Strict Prescription Criteria: To be prescribed Wegovy in the UK, a patient must typically have a Body Mass Index (BMI) of 30 or more, or a BMI of 27 or more alongside at least one weight-related health condition (like high blood pressure or pre-diabetes).
- It's Part of a Programme: Wegovy is most effective and is licensed for use in conjunction with a reduced-calorie diet and increased physical activity. It is a tool to support lifestyle changes, not a replacement for them.
Understanding this context is vital. Offering Wegovy isn't about providing a "quick fix"; it's about providing access to a comprehensive, medically-led health intervention.
The Corporate Health Insurance Solution: Bupa's Weight Management Pathway
Standard private medical insurance in the UK has a fundamental rule: it is designed to cover acute conditions that arise after you take out a policy. It does not typically cover the management of chronic (long-term) conditions like obesity, nor does it cover pre-existing conditions.
This is where the market is evolving. Insurers like Bupa are now offering specific, bolt-on modules that proactively address the root causes of future health claims.
Bupa's Weight Management pathway is a prime example of this new approach. Here’s how it works:
- It's an Add-On: This is not included in a standard corporate PMI policy. You must choose to add it to your company's plan, which will increase the premium.
- GP Referral: An employee experiencing issues with their weight would first consult a GP, who can refer them into the pathway if they meet the clinical criteria.
- Consultant-Led Care: The employee is then assessed by a specialist consultant (an endocrinologist or similar) who confirms the diagnosis and formulates a treatment plan.
- Holistic Programme: If appropriate, the plan may include a prescription for a GLP-1 medication like Wegovy or Saxenda. Crucially, this is delivered as part of a 24-month programme that includes:
- The cost of the medication.
- Regular consultations with the specialist.
- Support from dieticians, psychologists, and health coaches to help embed sustainable lifestyle changes.
The Cost of the Add-On:
The cost of adding a weight management pathway to your corporate health insurance policy will vary based on your company's demographics and the level of cover. As a guide, you can expect this to add anywhere from £15 to £40 per employee, per month to your premium. (illustrative estimate)
While this may seem significant, consider the alternative: the out-of-pocket cost for an individual to access Wegovy privately can be £200-£300 per month, plus the cost of specialist consultations. Providing it through a corporate scheme makes this life-changing treatment accessible and affordable for your staff. (illustrative estimate)
The Cost-Benefit Analysis: The Wegovy Add-On vs. The Cost of Inaction
Now we arrive at the central business case. By bringing together the cost of obesity and the cost of the insurance solution, we can perform a direct comparison.
Let's analyse the return on investment (ROI) for a hypothetical company with 250 employees.
| Metric | Scenario 1: No Wegovy Programme (The Cost of Inaction) | Scenario 2: With Bupa Wegovy Programme (The Investment) |
|---|---|---|
| Direct Financial Cost | £44,100+ annually in obesity-related absenteeism (from our earlier table). Plus unknown, higher costs of presenteeism. | £45,000 annually (assuming a mid-range add-on cost of £15 per employee per month: 250 x £15 x 12). |
| Employee Health & Productivity | Continued high rates of sick leave. Lower productivity from staff suffering with fatigue, pain, and poor mental health. Increased risk of long-term disability claims. | Reduced Absenteeism: If the programme helps just 10 employees avoid 4 sick days each, that's 40 saved days, recouping £7,000. Improved Productivity: Staff feel healthier, more energetic, and more focused. |
| Talent Attraction & Retention | Standard benefits package. May be perceived as lagging behind market-leading competitors who offer proactive wellness solutions. | Major Differentiator: A highly attractive, modern benefit that shows the company invests in employee wellbeing. Powerful tool for attracting and retaining top talent. |
| Organisational Risk | Higher risk of key personnel being absent for extended periods. Greater exposure to future claims on other benefits like Group Income Protection. | Proactive Risk Management: Addresses a root cause of ill health, potentially lowering future PMI and disability claims. Creates a more resilient, healthier workforce. |
| Company Culture & ESG | A reactive approach to health. Employees may feel unsupported in managing chronic health challenges. | Demonstrates a Culture of Care: Positions the company as a genuinely supportive employer. A tangible action that supports your Environmental, Social, and Governance (ESG) goals. |
The ROI Calculation:
In this scenario, the direct annual cost of the insurance add-on (£45,000) is almost identical to the minimum estimated cost of absenteeism (£44,100). This means that any reduction in sick leave, any improvement in productivity, and any success in retaining just one key employee who might have otherwise left for a competitor with better benefits, represents a positive return on investment.
The business case is not just about breaking even; it's about the significant upside that a healthier, more engaged workforce delivers.
Broader Considerations for HR Directors in 2026
Implementing a benefit like this requires careful strategic planning beyond the financial analysis.
- Equity and Fairness: How do you offer a benefit that only a portion of your workforce will be eligible for? The key is communication. Frame it as one part of a comprehensive, holistic wellness strategy that includes benefits for everyone, such as mental health support, gym memberships, and preventative health screenings.
- Other Insurers: While Bupa has been a vocal pioneer, other major UK private medical insurance providers like AXA Health, Aviva, and Vitality are all actively developing or have launched their own weight management services. The market is moving fast. This is why partnering with an expert PMI broker like WeCovr is essential. We can provide an impartial, whole-of-market comparison to find the policy that best fits your company's specific needs and budget.
- Tax Implications: Remember that private medical insurance is a Benefit-in-Kind (BIK). This means the value of the premium paid by the company is treated as taxable income for the employee, who will pay income tax on it. This needs to be clearly communicated to staff.
- Long-Term Strategy: These treatments are not a short course. What is your policy if an employee on the programme leaves the company? Clear communication about what happens to their treatment plan is vital.

People Also Ask: Quick Answers for Busy HR Leaders
Is Wegovy available on the NHS for everyone? No. Wegovy is available on the NHS but under very strict criteria and often with long waiting lists. It is typically reserved for use within specialist weight management services and is not available as a simple GP prescription for all who qualify by BMI.
Does standard corporate health insurance cover weight loss treatment? Generally, no. Standard private medical insurance in the UK is for new, acute conditions. Weight loss treatment is typically excluded as it relates to a chronic condition (obesity) or is considered a lifestyle choice. The new, specific add-on pathways from insurers like Bupa are the major exception to this rule.
What is the BMI requirement for a Wegovy prescription? The licensed indication for Wegovy is for adults with a Body Mass Index (BMI) of 30 kg/m² or greater (obesity), or a BMI of 27 kg/m² to 30 kg/m² (overweight) in the presence of at least one weight-related comorbidity, such as high blood pressure, type 2 diabetes, or high cholesterol.
Are there tax implications for offering staff private health insurance? Yes. Employer-paid private medical insurance is considered a 'Benefit-in-Kind' (BIK) in the UK. The cost of the insurance premium is reported on a P11D form, and the employee will pay income tax on that amount. National Insurance contributions may also be payable by the employer.
Your Next Steps
The evidence is clear. The cost of inaction on workforce obesity is substantial and growing. Proactive, clinically-led interventions, made accessible through corporate health insurance, offer a compelling ROI by reducing absenteeism, boosting productivity, and marking your organisation as a top-tier employer.
However, the market is complex and evolving rapidly. Navigating the different offerings from Bupa, Aviva, AXA, and others to find the right fit for your culture and budget requires specialist expertise.
