Weight Loss Clinics Near Me in the UK
If you're searching for weight loss clinics near you, you have two main options in the UK: NHS specialist weight management services and private weight loss clinics. NHS clinics are free but often have waiting lists, while private clinics offer faster access to prescription weight loss medication, dietitian support, and behavioural programmes. Understanding what's available locally and how to access each service will help you choose the right path for your weight management goals.

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 and Tier 3 Weight Management
The NHS weight management pathway is structured in tiers, with tier 3 and tier 4 services providing specialist care. Tier 3 weight management clinics are provided by your local Integrated Care Board (ICB) and typically offer structured behavioural support, dietary advice, and access to prescription weight loss medication including GLP-1 injections like Wegovy or Mounjaro.
- Refer yourself or ask your GP for a referral to your local tier 3 weight management service
- Services are free but availability varies significantly by region — some areas have waiting lists of 6–18 months
- You'll receive a full health assessment, including blood tests and discussion of medical history
- Treatment is tailored to your individual needs and may include medication, structured exercise programmes, and nutritional counselling
- Use our free BMI calculator above to check your current BMI — this helps determine your eligibility for NHS specialist services
Eligibility typically requires a BMI of 30 or above, or 27–29.9 with weight-related health conditions such as type 2 diabetes, high blood pressure, or sleep apnoea. For adults of South Asian, Chinese, Black African, or Black Caribbean heritage, lower BMI thresholds may apply.

Private Weight Loss Clinics and Online Prescribing Services
Private weight loss clinics in the UK offer faster access to specialist services without waiting lists. Many operate through online consultation models, allowing you to access a UK-licensed prescriber from home. These services typically cost £129–£320 per month depending on medication and dose.
- Online clinics assess your eligibility through a confidential health questionnaire and video consultation
- If approved, a prescription for Wegovy, Mounjaro, or other weight loss medication is issued and dispensed by a GPhC-registered pharmacy
- Services often include nurse support, progress tracking, and access to nutritional guidance
- You maintain full control over your treatment and can track your progress using our free progress tracker

Always verify that any private clinic uses a registered UK prescriber and is regulated by the General Pharmaceutical Council (GPhC).

Frequently Asked Questions
Common questions about BMI, weight loss medications, and our free UK tools.
How do I find a weight loss clinic near me in the UK?
Ask your GP for a referral to your local tier 3 NHS weight management service — they'll have details of clinics in your area. Alternatively, search online for "weight management services [your area]" or contact your local ICB directly. For private services, search for "online weight loss clinic UK" or "GLP-1 prescribing clinic". Always check they're regulated by the GPhC.
Are NHS weight loss clinics free?
Yes, NHS weight management services are completely free, including appointments, assessments, and any prescribed medications. However, waiting times vary by region — some areas have waits of several months. Private clinics charge monthly fees ranging from £129–£320 depending on medication and support level.
What medications do weight loss clinics prescribe?
NHS and private clinics in the UK may prescribe Wegovy (semaglutide), Mounjaro (tirzepatide), or Saxenda (liraglutide) for eligible patients. These are GLP-1 or dual GIP/GLP-1 receptor agonist injections. Clinical trials show these medications may help people lose an average of 15–21% of body weight alongside dietary changes and exercise — though individual results vary significantly.
What's the difference between NHS and private weight loss services?
NHS services are free but often have long waiting lists and may have limited medication availability depending on your region. Private services cost money but offer faster access, no waiting lists, and often more flexible appointment times. Both require a clinical assessment to ensure the treatment is suitable for you.
Do I need a referral from my GP to access weight loss clinics?
For NHS tier 3 services, you can self-refer directly or ask your GP for a referral — both routes work. For private online clinics, you don't need a GP referral; you contact the clinic directly and undergo their own clinical assessment. Either way, a qualified prescriber will assess your suitability before prescribing any weight loss medication.
