How to Get Weight Loss Injections on a Private or NHS Route

Weight loss injections such as Mounjaro and Wegovy are prescription-only medicines (POMs) in the UK; a clinical assessment is legally required before any supply.
Two licensed routes exist: NHS access (phased criteria apply and waiting lists are common) or private prescription through a GPhC-registered pharmacy such as nume.
Eligibility turns on BMI and weight-related health conditions, not just weight alone — lower BMI thresholds can apply for some ethnic backgrounds under UK guidance.
A genuine prescriber reviews your consultation before any medicine is issued; any seller offering these injections without that step is acting outside the law.

To get weight loss injections in the UK, you need a prescription from a qualified prescriber following a clinical assessment — there is no legal route around that step. Both Mounjaro (tirzepatide) and Wegovy (semaglutide) are prescription-only medicines, available privately through a regulated pharmacy service or, for those who meet strict criteria, through the NHS. The right route depends on your BMI, your health history, and whether your area currently offers access. A prescriber (not a website form) makes the final call on suitability.

The facts about getting weight loss injections: what most people get wrong, and what actually happens

The biggest misconception: these injections are like buying vitamins online

A question our prescribers hear most weeks goes roughly like this: "Can't I just order them and start?" It is understandable. The marketing noise around GLP-1 medicines can make them sound as straightforward as a supplement subscription. They are not. Mounjaro and Wegovy are prescription-only medicines regulated by the MHRA, which means a qualified prescriber must assess your medical history, current medicines, BMI, and any relevant conditions before any pen is dispensed. That assessment is not a formality you tick past, it is the mechanism that keeps the medicine safe for you specifically.

The practical upshot: if you see a website offering to send you weight loss injections without gathering that clinical picture, something is wrong. The safe places to get weight loss injections are all regulated, all require a prescriber to sign off, and all verify your identity. Anything outside that pattern is either illegal or selling something counterfeit. The MHRA has seized large quantities of fake pens in recent years and warns that some contained entirely wrong substances.

Understanding this changes how you approach the question. You are not shopping for a product. You are starting a clinical process. That process protects you, and (done well) it moves quickly.

NHS or private: what actually determines which route you can use

The NHS does prescribe both Mounjaro and Wegovy, but access is phased and the criteria are tighter than the licensed indications. As of summer 2026, NHS tirzepatide is available for adults with a BMI of 40 or above plus four or more specified weight-related conditions (from around June 2026, those with a BMI of 35–39.9 and four or more conditions joined the eligible cohort). Wegovy via the NHS is routed through specialist weight management services, with its own NICE criteria and commonly long waiting lists. NICE's appraisal of tirzepatide (TA1026) sets out the qualifying thresholds in detail.

Private prescription is the alternative for people who do not meet NHS thresholds, do not want to wait, or simply prefer a different experience. The licensed eligibility for private prescription follows the medicine's own 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, or obstructive sleep apnoea. Who can get weight loss injections covers the full breakdown, including the lower BMI thresholds that apply for some ethnic backgrounds.

Neither route guarantees approval. A prescriber weighs the whole clinical picture. That is true whether the consultation happens in a GP surgery or through a regulated online service.

How the private prescription route actually works, step by step

The private route is faster than most people expect when it runs through a properly regulated service. At nume, the process works like this: you complete a free clinical consultation online, answering questions about your health, medicines and goals. A GPhC-registered Independent Prescriber (a real clinician, not automated software) reads your answers the same day. If the medicine is clinically suitable, your prescription is issued and your pen is dispatched from our GPhC-registered pharmacy the same working day if you order before 12pm, arriving with DPD the next working day in plain unbranded packaging.

Identity and weight are verified as part of the process. Transfers from another provider require evidence of your current treatment and dose. Repeat orders are re-reviewed clinically before each supply, there is no automatic renewal that bypasses a prescriber. If you are weighing up whether the private route makes sense for your situation, the NHS free access page explains what is currently funded and what is not, which helps clarify whether waiting for an NHS slot is realistic.

One practical note on what to have ready: a rough sense of your current weight and height, details of any prescription medicines you take, and any relevant diagnosed conditions. If you want a full walkthrough of how to get the weight loss injection, including what to expect at each stage, that page takes you through the process from first consultation to delivery. The consultation is straightforward, but it is a real clinical form, more like a GP intake questionnaire than a checkout page.

What to check before using any online pharmacy

The safest thing you can do before handing over any personal or health information to an online pharmacy is look it up on the GPhC register. Every legitimate online pharmacy operating in the UK must be registered with the General Pharmaceutical Council. You can check any pharmacy (including nume) at the GPhC premises register, which is publicly searchable. If a pharmacy is not listed, stop.

Beyond the register, a few red flags are worth knowing. A legitimate pharmacy offering prescription-only weight loss injections will always require a clinical assessment. It will not offer these medicines without one, will not use discount codes as a marketing tool for POMs, and will not promise approval before your consultation is reviewed. The weight loss injection overview page covers the landscape of what is licensed and what to look for in a regulated provider.

For most people reading this, the question of how to get weight loss injections has a clear answer: go through a properly regulated route, have an honest consultation, and let a qualified prescriber make the call. That is not a barrier, it is the point. The medicine works because it is clinically matched to the person taking it. If you are also thinking about cost, our best value weight loss injections page compares your options and explains what is included in the price. See our FAQs if you have specific questions about the consultation process, or take a look at the treatment options page for an overview of what is available through nume.
