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.
NHS Weight Loss Services in Your Area
The NHS provides free specialist weight management services through tier 3 and tier 4 clinics, but access varies significantly by region. To find an NHS weight loss clinic near you:
- Ask your GP for a referral — your doctor can refer you to your local integrated care board (ICB) weight management service
- Check your ICB website — each region publishes information about available services and waiting times
- Expect waiting lists — many areas have substantial delays of several months to over a year
- Access tier 3 first — NHS typically offers community-based support before specialist services; prescription medications like Mounjaro or Wegovy are usually initiated within tier 3 specialist services
NHS weight management services include dietary advice, behaviour change support, and — if clinically appropriate — prescription weight loss medication. Services typically combine lifestyle intervention with medical treatment for best results.

Frequently Asked Questions
Common questions about BMI, weight loss medications, and our free UK tools.
Do I need a GP referral to access weight loss treatment in the UK?
For NHS specialist services, yes — your GP must refer you to your local weight management clinic. Private clinics and online prescribing services do not require a GP referral; you can access them directly. However, informing your GP is advisable so they have a record of your treatment.
What prescription weight loss medications are available near me?
The main prescription options in the UK are Mounjaro (tirzepatide), Wegovy (semaglutide), and Saxenda (liraglutide). Eligibility depends on your BMI and health conditions. NHS services typically access Mounjaro or Wegovy through tier 3 specialist services; private providers offer the same medications following online clinical assessment.
How long are NHS weight loss clinic waiting lists?
Waiting times vary by region (ICB). Some areas have waits of 3–6 months; others exceed 12–18 months. Contact your local ICB directly or ask your GP for current waiting times in your area. Private services typically offer faster access — sometimes within 1–2 weeks.
Are weight loss injections like Wegovy available on the NHS near me?
Yes, but access is regional and limited. Wegovy and Mounjaro are licensed for NHS use within specialist tier 3 weight management services. Availability depends on your local ICB's commissioning. Ask your GP or contact your local weight management service directly to confirm availability in your area.
What's the difference between NHS and private weight loss clinics?
NHS clinics are free but have longer waiting times and regional availability gaps. Private clinics charge but offer faster access and may provide additional services. Both can prescribe licensed weight loss medications. Try our free GLP-1 weight loss calculator above to estimate potential outcomes with prescription medication, regardless of which service you choose.
