What's the price of Mounjaro for private weight-loss treatment in the UK?

Why Mounjaro prices vary so widely between providers

The range quoted across the private market reflects several real differences. Dose is the biggest factor: the 2.5mg starting pen sits at one end of the cost spectrum, while the 15mg maintenance pen (following Lilly's September 2025 list-price increase, which pushed that dose's price from around £122 to around £330 per pen) sits at the other. As widely reported at the time, that repricing changed the market considerably, and if you want to understand what the new Mounjaro prices look like across each dose, providers adjusted their own pricing accordingly.

Beyond dose, providers structure their services differently. Some clinics charge a consultation fee on top of the medicine price. Others add a prescription fee, or bill for delivery. Aftercare (dose-review calls, access to a prescriber when something unexpected happens) is sometimes bundled in and sometimes sold separately. A tirzepatide price comparison that ignores these variables can mislead you into thinking two quotes are comparable when they're not.

NICE's appraisal of tirzepatide, TA1026, confirmed Mounjaro's clinical profile in adults with a BMI of 35 or above alongside a weight-related health condition, and the NHS rollout is under way, but on strict phased criteria. For anyone who doesn't currently qualify for NHS treatment, or who doesn't want to wait, private treatment is the practical route. Knowing what a private price should include helps you choose wisely.

What a headline price often leaves out

A question our prescribers hear regularly: "I found it for £X, why does yours look different?" The gap is almost always explained by what the lower figure excludes.

Clinical assessment is the most commonly omitted item. Mounjaro cannot legally be dispensed in the UK without a valid prescription from a qualified prescriber who has reviewed your health history. Some providers charge that assessment separately; others skip a meaningful review entirely, which is a patient-safety concern, not a bargain. You can read more about what a thorough clinical review involves on the Mounjaro treatment page.

Delivery charges are another variable. Next-working-day tracked delivery (the kind that arrives reliably and stays in temperature-controlled conditions) costs money to arrange properly. Factor that in when comparing totals. Ongoing clinical support matters too: a dose change or a side-effect question mid-treatment needs a prescriber available to answer it, and that service has a cost whether or not it's broken out on the invoice. If you're uncertain whether a quoted price is truly all-in, our FAQs cover what to look for.

Where nume positions itself, and why

We are deliberately not the cheapest provider in this market. That's a conscious choice, not an oversight.

Our single transparent price covers the clinical consultation, the prescription, the medicine, free next-working-day DPD delivery in plain unbranded packaging, and priority aftercare seven days a week. No hidden fees surface at checkout. Every repeat order is clinically re-reviewed by a GPhC-registered Independent Prescriber, a real clinician reads your answers, not software routing you through a checklist. You can verify our pharmacy on the GPhC register (registration 9012878).

We source Mounjaro through the licensed UK supply chain, with an authorised relationship with Eli Lilly UK. Your pen sits in a fridge at our GPhC-registered pharmacy until dispatch, not in a warehouse with uncertain provenance. Current treatment pricing is shown on our consultation and treatment page; we don't print per-pen prices in page copy, because pricing is reviewed as the market moves and we'd rather you see the current figure than a stale one.

Why "cheapest" is the wrong test for a prescription medicine

Price comparison is a reasonable instinct. But for a prescription-only medicine like Mounjaro, the lowest number answers the wrong question. The MHRA has warned publicly about counterfeit weight-loss pens circulating online, some containing insulin rather than tirzepatide. In 2025 alone, approximately 20 million doses of illegally traded weight-loss medicines with a street value around £45 million were seized, and the first UK site manufacturing fake tirzepatide pens was raided. The MHRA's Yellow Card scheme lets you report suspected fakes or unsafe sellers.

Red flags include sellers offering Mounjaro without requiring any clinical assessment, prices far below the market range, and discount codes or vouchers from unverified sources. If you're trying to work out what the cheapest legitimate Mounjaro option looks like and what corners you can safely cut, it helps to understand that a genuine, well-run pharmacy has overhead (prescribers on salary, regulated premises, a cold chain) and its pricing reflects that. For more on how Mounjaro pricing has shifted and where it may go from here, including what the new price of Mounjaro is expected to be, see our dedicated page on the topic, and for a breakdown of where tirzepatide's lowest price sits across the market, that page sets out what you can realistically expect to pay. The right metric isn't the smallest number on the page; it's clinical rigour, supply-chain transparency, and a prescriber who actually knows your case.
