Private clinic weight loss injections: what actually shapes the decision

Why 'private clinic' means different things for weight loss injections

When people search for a private clinic for weight loss injections, they usually picture a physical building. That's a reasonable starting point, but the regulatory reality is broader. A GPhC-registered online pharmacy with its own Independent Prescribers carries the same legal obligations as a bricks-and-mortar clinic, the prescription must be issued by a qualified clinician who has assessed you, the medicine must come from a licensed UK supply chain, and the pharmacy must be verifiable on the GPhC register.

What varies between providers is the shape of that clinical encounter. An in-person appointment at a private weight management clinic gives you a face-to-face conversation; a regulated online pharmacy typically uses a structured consultation form, reviewed personally by a prescriber, sometimes alongside a video call for identity and weight verification. Neither is inherently safer than the other, the legal and clinical standard required is identical. What matters is whether the provider meets it.

A common misconception is that online services skip the clinical gatekeeping entirely. Legitimate ones don't. The prescriber still reviews your full medical history, your current medications and your BMI before deciding whether to issue a prescription. If you want to check any provider's credentials, the GPhC's public register takes under a minute to search.

Our clinical team at nume reviews every consultation personally (a real prescriber, not automated software) and that applies to first consultations and every repeat order.

Which injection, and does your situation fit the licensed criteria?

Both licensed injections work on gut-hormone pathways to reduce appetite and slow gastric emptying, but they're not identical. Mounjaro (tirzepatide) activates two receptors (GIP and GLP-1) making it the only dual-agonist weight-loss medicine available in the UK. Wegovy (semaglutide) targets GLP-1 alone. In the SURMOUNT-5 head-to-head trial, published in the New England Journal of Medicine in 2025, tirzepatide produced greater average weight reduction than semaglutide 2.4 mg over 72 weeks, though both medicines showed meaningful results in their own large trials.

The licensed eligibility criteria for private prescribing are straightforward in principle: adults with a BMI of 30 or above, or a BMI of 27 or above with at least one weight-related condition such as high blood pressure, type 2 diabetes, high cholesterol or obstructive sleep apnoea. Lower BMI thresholds apply for some ethnic backgrounds under UK guidance. A BMI figure alone doesn't settle it, the prescriber looks at the full clinical picture, including any contraindications.

Treatment is not recommended during pregnancy, while breastfeeding, or when trying to conceive. It is not licensed for under-18s. Anyone with a history of medullary thyroid carcinoma or certain gastrointestinal conditions will need to discuss this with a prescriber before starting. The NHS medicines page for tirzepatide sets out the side-effect profile and key precautions clearly, and is a good reference before any consultation.

If you want to understand the full range of weight loss injections available in the UK, including how the two medicines compare, that's a useful place to start before deciding which route to pursue.

What private pricing actually reflects, and what to check

Cost is rarely the cleanest signal when choosing between private providers. A low headline figure sometimes reflects a stripped-back service: no prescription fee included, delivery charged separately, no structured aftercare, and no clinical review before a repeat order is sent. A higher price may include all of those things in one transparent total, or it may not. The only way to know is to check what's included line by line.

Since Eli Lilly raised the UK list price for Mounjaro from 1 September 2025, the highest-dose pen's list price rose to around £330; typical private prices across providers now range roughly £149 to £375 per month depending on dose and supplier, as widely reported. These figures give a sense of the market; they are not a floor or a ceiling for any individual provider.

And if you're weighing a private clinic against NHS access, the NHS route for weight loss injections has its own eligibility rules and waiting-list realities worth reading first.

One practical note: discount codes for prescription medicines from unverified sellers are a red flag, not a saving. The MHRA has warned repeatedly about counterfeit weight-loss pens circulating online, some containing harmful substances. Any supplier offering these medicines without a clinical assessment falls outside the law. Verify the pharmacy on the GPhC register before you hand over any personal or payment information.

How the clinical process works at a regulated online pharmacy

At nume the process is built around the same clinical standards a physical clinic operates under, delivered without the need for travel or waiting-room appointments. You complete a free consultation; a GPhC-registered Independent Prescriber reads your answers the same day and makes a clinical decision. Identity is verified by photo ID, and weight is confirmed on a live video call, not taken on trust. If the prescriber approves treatment, your prescription is issued and the medicine is dispatched the same day for orders placed before 12pm on a weekday, arriving the next working day via tracked DPD delivery in plain packaging.

Every repeat order goes through clinical re-review before it's approved. There are no subscriptions, no auto-renewals. If something changes in your health between orders, that's the moment the prescriber catches it.
