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 10mg Costs — NHS vs Private Access
Private prescription costs for Mounjaro 10mg typically range from £180–£250 per dose (approximately £720–£1,000 per month) through UK-registered online pharmacies following a clinical assessment. Each KwikPen contains 4 weekly doses. Costs vary by provider and may include online consultation fees. NHS access is available but limited — tirzepatide (Mounjaro) is approved by NICE for specialist weight management services, yet availability remains inconsistent across regions. Most areas have long waiting lists for tier 3 specialist services. If eligible, NHS prescription costs apply (currently £11.65 for a private prescription equivalent, though NHS typically covers the full cost for approved patients). The 10mg dose is typically reached after 8–12 weeks of dose titration, starting at 2.5mg and escalating gradually.
- Private online prescription: £180–£250 per dose
- NHS access: through specialist weight management services (varies by region)
- Dose titration: 2.5mg → 5mg → 7.5mg → 10mg over 8+ weeks
- Online consultation fees: typically £20–£50 (sometimes included)

How to Access Mounjaro — NHS Route vs Private Route
NHS route: Request a referral to your local tier 3 or tier 4 weight management service from your GP. Eligibility requires BMI ≥30 or BMI 27–29.9 with weight-related health conditions (type 2 diabetes, hypertension, cardiovascular disease). Waiting times can be months to years depending on your region. Private route: Complete an online consultation with a UK-licensed prescriber through a GPhC-registered pharmacy. The prescriber reviews your medical history and decides suitability — no NHS referral needed. If approved, a prescription is issued and dispensed the same or next day. Private access is faster but at higher cost. Both routes require a clinical assessment; Mounjaro is never supplied without a prescription.

Frequently Asked Questions
Common questions about BMI, weight loss medications, and our free UK tools.
How much does Mounjaro 10mg cost privately in the UK?
Private Mounjaro 10mg typically costs £180–£250 per dose through UK online pharmacies, or approximately £720–£1,000 per month (4 doses). Online consultation fees (£20–£50) may apply separately. Costs vary between providers. Always confirm the total cost before proceeding.
Can I get Mounjaro 10mg on the NHS in the UK?
Yes — NICE has approved tirzepatide for NHS specialist weight management services. However, NHS availability is inconsistent across regions, with significant waiting lists. You'll need a GP referral to a tier 3 specialist service and meet eligibility criteria (BMI ≥30 or BMI 27–29.9 with weight-related health conditions).
How long does it take to reach the 10mg Mounjaro dose?
The 10mg dose is typically reached after 8–12 weeks. Titration starts at 2.5mg and escalates weekly: 2.5mg (weeks 1–4), 5mg (weeks 5–8), 7.5mg (weeks 9–12), then 10mg (weeks 13+). Your prescriber may adjust this timeline based on tolerability and side effects.
What's included in the cost of Mounjaro — just the injection?
Private costs typically cover the medication only. Online consultation fees (£20–£50) are usually separate but sometimes included in total package prices. NHS costs are covered by the NHS if prescribed through a specialist service. Check with your provider for a full breakdown.
Is Mounjaro 10mg the maximum dose I'll receive?
No — 10mg is a mid-range dose. Titration typically continues through 12.5mg up to the maximum of 15mg, depending on your response and tolerability. Your prescriber will decide when to escalate based on your individual needs and how well you're managing side effects.
