What Is BMI and Why Does It Matter?
Body Mass Index (BMI) is the most widely used screening tool for assessing whether your weight falls within a healthy range. Used by the NHS, GPs, and weight management services across the UK, BMI provides a quick snapshot of your weight relative to your height. The formula is simple: your weight in kilograms divided by your height in metres squared (kg/m²).
While BMI isn't a perfect measure — it doesn't account for muscle mass, bone density, or fat distribution — it remains the standard first step in identifying potential weight-related health risks including type 2 diabetes, cardiovascular disease, high blood pressure, and certain cancers.
The NHS also recommends adjusted thresholds for people of South Asian, Chinese, or Black African heritage — a BMI of 23 or above is classified as overweight, and 27.5 as obese. Our calculator includes this adjustment as a one-click toggle.
Mounjaro 7.5mg Cost and Prescription Access in the UK
Private prescription costs: In the UK private market, a single KwikPen containing 4 doses of Mounjaro 7.5mg typically costs between £180–£250 per month, depending on the provider and whether you're accessing it as a new customer or existing patient. Monthly costs assume you're paying for one pen per month at this dose level. This price includes the clinical assessment by a UK-licensed prescriber and pharmacy dispensing fees.
What affects pricing: Some providers offer tiered pricing based on initial consultation costs (£20–£50) versus repeat prescription costs (lower after first assessment). A few online providers bundle multiple months at a discount. Always check whether the quoted price includes the consultation fee or is for medication only.
- Initial online consultation: typically £20–£50 (one-time or per assessment)
- Monthly prescription cost: £180–£250 per month depending on provider
- Storage and delivery: usually included in quoted price
Compared to other doses: The 7.5mg dose falls in the mid-price range — 5mg is slightly cheaper, while 10mg and above cost more. You can try our free weight loss calculator to compare projected outcomes at different dose levels.

NHS vs Private Access — And How to Get Mounjaro in the UK
NHS access: Mounjaro for weight management is available through NHS specialist tier 3/4 weight management services, not through your GP directly. You'll need referral from your GP to a local specialist service, which varies significantly by region and availability. NHS waiting lists for specialist services can extend from several months to over a year in many areas. When prescribed through the NHS, there is no direct cost to you.
Private access: You can obtain a Mounjaro prescription through a private online consultation with a UK-licensed prescriber without needing NHS referral. The process typically takes 24–48 hours: complete an online health questionnaire, have a consultation with a prescriber (video or phone), and if approved, your prescription is sent to a GPhC-registered pharmacy for dispensing and delivery. This route is faster but requires payment.
Which route suits you? Choose NHS if you're willing to wait and have no cost concerns. Choose private if you want faster access and can fund treatment privately.
