How to get a weight loss injection on the NHS — and what to do if you can't

Whether the NHS route is actually open to you

The NHS does prescribe tirzepatide and semaglutide (Wegovy) for weight management, but access depends on criteria that most people don't currently meet. NICE's appraisal of tirzepatide (TA1026) recommends it for adults with a BMI of 35 or above plus four or more specific weight-related conditions from a defined list: type 2 diabetes, high blood pressure, dyslipidaemia, obstructive sleep apnoea, or cardiovascular disease. From around June 2026, the BMI threshold drops to 35 for people with four or more of those conditions, and a third cohort at BMI 40 with three conditions is expected around March 2027. Lower BMI thresholds apply for some ethnic backgrounds under UK guidance. Wegovy on the NHS is available through specialist weight management services under NICE TA875, where waiting lists are commonly long.

If you're asking "can I get the weight loss injection on the NHS?" the honest answer is: only if your GP practice is participating in the new prescribing programme and your numbers fit the current cohort. Even then, every patient must take part in wrap-around diet and activity support. Meeting the criteria doesn't guarantee a referral today, it depends on your local service and how far along the rollout your area is. The NHS England weight management injections page sets this out clearly and is worth reading before you approach your GP.

What changes when you go private

A private regulated pharmacy like nume can prescribe tirzepatide or semaglutide for weight management outside the NHS framework, subject to clinical suitability. The licensed eligibility threshold for private prescribing follows the medicine's UK marketing authorisation: adults with a BMI of 30 or above, or 27 or above with at least one weight-related condition such as high blood pressure, high cholesterol, prediabetes, type 2 diabetes, or obstructive sleep apnoea. A prescriber still makes the final call, BMI alone never guarantees approval.

The process at a GPhC-registered online pharmacy should mirror the safety of a face-to-face consultation. At nume, that means photo-ID verification, live weight confirmation on video, a review of your medical history, and a GP notification in line with GPhC guidance. Your answers go to a named GPhC-registered Independent Prescriber who reads them the same day. You can check whether any online pharmacy is legitimately registered at the GPhC register, our registration number is 9012878. If a site is not listed there, do not use it.

The fake-pen risk, why this matters for the NHS question too

Demand for these medicines has created a market for counterfeits. The MHRA has warned publicly about fake weight-loss pens sold via social media and unregistered websites, and in October 2025 enforcement teams raided the first illicit UK site producing counterfeit tirzepatide pens. Some fake devices have contained insulin rather than the labelled medicine, causing serious harm. The MHRA's Yellow Card scheme accepts reports of both suspected side effects and suspect sellers, use it if you encounter an offer that seems off.

Red flags: a seller offering these medicines without a prescription, prices far below what a legitimate clinical service would charge, or a website with no verifiable GPhC registration. There is no such thing as a legitimate "discount code" for a prescription-only medicine from an unverified source. If you're considering a private route, our guide to weight loss injections explains what a legitimate supply chain looks like and why it matters.

Making the decision: NHS wait or private consultation?

This is the practical question most people are actually trying to resolve. If you meet the current NHS criteria, it's worth speaking to your GP, treatment through the NHS is free and clinically supported. If you don't meet the thresholds, or your practice isn't yet part of the rollout, or you'd rather not wait, a regulated private service is the legal alternative, and you can order weight loss injections through us once a prescriber has confirmed you're suitable. Some people start privately and later transition to NHS care as the rollout broadens; others do the reverse.

Timing matters in small ways too, if you're mid-month and payday is still a week away, or you've got a holiday coming up, those are worth factoring into when you start a titration. Our prescribers are available to answer questions like that as part of the free consultation. There's no pressure and no subscription; every repeat order is reviewed individually before anything is sent. If you'd like to explore the private route, speak to our prescribers, the consultation is free, and you'll have a clinical answer the same day.
