Getting the weight loss injection privately: what you actually need to know

You've looked at the NHS option — and found out it's not straightforward

Most people researching private weight loss injections have already tried to find out whether they qualify on the NHS. The answer is usually complicated. As of mid-2025, NHS tirzepatide access under NICE's appraisal TA1026 required a BMI of 40 or above alongside four or more specific conditions. The criteria are loosening in phases (a lower BMI band opened in June 2026) but millions of people who would clinically benefit don't yet qualify, or do qualify but face long waits through specialist services. You can read a full breakdown of NHS eligibility for weight loss injections separately. The private route is the alternative for everyone in that gap. It operates under the same legal framework: a prescription-only medicine, issued only after clinical review, dispensed by a pharmacy registered with the GPhC.

That last point matters more than it sounds. GPhC registration is the baseline you should verify before handing over payment. The register is publicly searchable at pharmacyregulation.org, it takes about thirty seconds. If a pharmacy isn't on it, stop there.

What the private process actually looks like

The practical steps are simpler than many people expect. You complete a clinical consultation, typically an online form reviewed by a prescriber, sometimes with a video element for weight verification. A GPhC-registered Independent Prescriber reads your answers. If treatment is clinically suitable, they issue a prescription. The pharmacy dispenses, and your pen arrives. At nume, if you get your consultation in before midday on a weekday, a prescriber reviews it the same day; approved orders are dispatched that afternoon and delivered free by DPD the next working day, in plain packaging. It fits around a normal day, many people sort it during a lunch break rather than taking time off to see a GP.

Repeat orders follow the same pattern. A prescriber reviews your case again before anything is dispensed. There are no automatic renewals. Each clinical review is a real check, not a formality. Our approach to clinical oversight and what that means in practice is set out on our about page.

Who private treatment is open to

The private licensed eligibility for Mounjaro and Wegovy follows the medicines' UK licences. Adults with a BMI of 30 or above, or 27 or above alongside at least one weight-related condition such as high blood pressure, type 2 diabetes, high cholesterol, obstructive sleep apnoea or cardiovascular disease, can be considered. Lower BMI thresholds apply for some ethnic backgrounds under UK clinical guidance. A BMI figure alone is not the whole picture, the prescriber assesses your full health history, current medicines and any contraindications before deciding whether treatment is suitable. Pregnancy, breastfeeding and trying to conceive all rule out these medicines; neither is licensed for under-18s.

If you want to know whether you're likely to be eligible before starting a consultation, the eligibility criteria for weight loss injections page lays them out clearly. You can also use the NHS BMI calculator to check your own number first.

The one thing to check before choosing a private provider

Price matters to most people, that's reasonable. There is a useful explainer on how much weight loss injections cost privately if you want the full context. The short version: private treatment prices vary by dose and provider, and the cost rose significantly after Eli Lilly's UK list-price increase in September 2025. What varies more than the headline price is what's included. Some providers charge separately for consultations, prescriptions, aftercare calls and delivery. Others bundle everything. If you're still weighing up your options, a practical guide to how to get weight loss injections privately walks through each step so you know what to expect before you commit. Knowing what a quoted price actually covers is the comparison that matters, not just the per-pen figure.

Beyond cost, the safety question is straightforward: only use a pharmacy you can verify on the GPhC register. The MHRA has warned repeatedly about counterfeit weight loss pens sold through social media, some have contained insulin rather than the stated medicine, leading to hospitalisations. Fake pens often undercut market prices considerably, which is exactly why an unusually low price is a warning sign rather than a bargain. Report any suspect sellers via the MHRA's Yellow Card scheme. A broader look at what private weight loss injections involve covers the safety infrastructure in more detail, and if you'd prefer to collect in person rather than wait for delivery, our page on local pharmacy weight loss injections explains how that works.
