Mounjaro price in London: what does private treatment actually cost?

How does Mounjaro pricing in London actually work?

London has no shortage of private weight-loss clinics and online pharmacies willing to supply Mounjaro, but the advertised monthly figure rarely tells the full story. Pricing is set per pen (each pen contains four weekly doses) and climbs with each strength step, from the 2.5 mg starter through to the 15 mg maintenance dose. Following Eli Lilly's September 2025 UK list-price increase, the higher-dose pens rose sharply: the 15 mg pen's list price moved from around £122 to around £330, and private market prices followed suit. As widely reported in August 2025, that change reset what Londoners should expect to pay at the top of the titration schedule.

One practical reality: Mounjaro treatment starts at 2.5 mg because that first pen is about giving your system time to adjust, not about delivering the therapeutic dose. The dose most providers quote in their headline price may not be the one you'll be on after three or four months. When comparing providers, it's worth asking what you'll pay at 7.5 mg or 10 mg, not just at the starting strength. The full Mounjaro price guide breaks this down by dose for context.

Mounjaro is licensed by the MHRA for weight management in adults with a BMI of 30 or above, or 27 or above with at least one weight-related health condition. NICE's appraisal of tirzepatide recommends it for eligible adults within specific criteria, you can read NICE's tirzepatide guidance (TA1026) in full. Clinical suitability is assessed by the prescriber at consultation; a BMI figure alone doesn't determine approval.

What do headline Mounjaro prices in London often leave out?

The number on a clinic's booking page or a pharmacy's product listing frequently covers the medicine and little else. Consultation fees can run anywhere from £20 to over £100 for the initial assessment, charged separately. Prescription fees are sometimes itemised on top. Delivery in London (even from a registered online pharmacy) isn't always free, and next-day services can add a meaningful amount to each order.

Aftercare is the less visible cost. Mounjaro is titrated over months; dose increases happen step by step, and a prescriber needs to review your progress before each change. Some providers charge for those reviews. Support between orders (whether that's a question about side effects or a missed dose) may sit behind a paid subscription or a per-contact fee. None of those elements are optional: they're part of safe, clinically supervised treatment.

The Mounjaro price increase explained page covers what drove the September 2025 change and what it means for ongoing treatment costs. And if the 5 mg pen is where you're currently sitting on your titration plan, our breakdown of the Mounjaro 5 mg price gives specific context for that dose, with further detail on what that strength typically costs available on the Mounjaro 5 mg price page.

What does nume include, and is it the cheapest option in London?

We don't compete on price. That's a deliberate choice. At nume, one transparent figure covers the consultation, the prescription, the medicine, tracked next-working-day DPD delivery to anywhere in the UK including London, and access to priority prescriber support seven days a week. There are no add-ons, no monthly membership fees, and no auto-renewals, every repeat order is independently reviewed by a named clinician before it's processed.

Clinically, the process works like this: complete a free consultation online, and a GPhC-registered Independent Prescriber personally reviews your answers the same day. Identity and weight are verified directly. If treatment is clinically appropriate and you order before noon on a working day, your pen is dispatched the same day. You can verify our GPhC pharmacy registration at any point, registration number 9012878 on the GPhC register.

If you're comparing providers and want to understand whether our pricing stacks up, you can see how we keep Mounjaro prices low and what that involves. More on how our model works is on the about us page.

Why cheapest is the wrong question for a prescription medicine

This is especially true for Mounjaro. The MHRA has documented serious consequences from fake pens sold online, including counterfeit products containing insulin and hospitalisations. In October 2025, the first UK manufacturing site producing counterfeit tirzepatide pens was raided. The agency seized roughly 20 million doses of illegally traded weight-loss medicines with a street value of around £45 million. These weren't sold through registered pharmacies, they were sold through social media and unverified websites, often at prices that seemed attractive.

The red flags are consistent: offers of Mounjaro without a prescription, prices well below the going market rate, sellers operating outside the NHS and GPhC-regulated supply chains. The MHRA's guidance on reporting suspect sellers via the Yellow Card scheme is worth bookmarking. Any pharmacy supplying a POM legitimately will be verifiable on the GPhC register, the two minutes that check takes is the most useful thing you can do before handing over payment details.

For Londoners weighing up private options, the price comparison is a reasonable starting point. It's just not the finishing one. If you want to see whether you're clinically suitable and what treatment would look like through a regulated provider, the free consultation costs nothing and commits you to nothing.
