NHS vs private weight-loss jabs: how to get Mounjaro or Wegovy in the UK

One of the first questions UK patients ask is simple: can I get a weight-loss jab on the NHS, or do I have to pay privately? The honest answer is “it depends” — on the medicine, your BMI, your health conditions and where you live. Here is how the NHS and private routes compare in 2025.

Getting a weight-loss jab on the NHS

On the NHS, GLP-1 weight-management medicines have generally been made available through specialist weight-management services rather than handed out at a standard GP appointment. Access is prioritised for people with a higher BMI (often 35+, or 30+ with weight-related health conditions such as type 2 diabetes, high blood pressure or sleep apnoea). Availability is being phased in over time and can vary by region, so waiting lists are common.

• Cost: little or no out-of-pocket cost for the medicine (standard prescription rules apply).
• Access: usually via referral to a specialist service, often with waiting times.
• Eligibility: tighter BMI and health-condition criteria.

Going private

Private online pharmacies and clinics have made Mounjaro and Wegovy widely accessible after an online consultation. You typically pay per pen (roughly a four-week supply), and you can usually start sooner than via the NHS route. The trade-off is cost — and the fact that private prices vary a lot between pharmacies.

• Cost: commonly £150–£250 a month depending on drug, dose and pharmacy.
• Access: fast, after an online clinical assessment.
• Eligibility: still requires meeting clinical criteria, but often more accessible.

How to decide

If you meet NHS eligibility and can wait, the NHS route removes the cost burden. If you do not qualify, or the wait is too long, the private route offers faster access — but it is worth comparing pharmacies carefully because the same pen can cost noticeably more at one pharmacy than another.

Tracking either way

Whether you are on the NHS or paying privately, JabDay helps you stay on top of your jab schedule, titration ladder, side effects and weight. If you are private, the cost tracker shows whether you are overpaying and how much you could save by switching pharmacy. If you are on the NHS pathway, JabDay simply tracks your journey at £0 out-of-pocket — with a GP-ready report you can take to your next appointment.
