Mounjaro Price List: How UK Private Costs Actually Compare

What changed in September 2025, and why the price list shifted

The clearest starting point for any Mounjaro price list comparison is what happened to supply costs. Eli Lilly raised its UK list price for Mounjaro from 1 September 2025; the highest maintenance dose, which had sat at around £122 for a four-week pen, rose to around £330. Private providers absorbed or passed on that increase at different rates, which is part of why the market range is now so wide. The full picture of Mounjaro pricing in the UK is harder to read than it looks because doses vary, titration schedules vary, and what's actually included in the quoted price varies enormously.

NICE's appraisal of tirzepatide (TA1026, published December 2024) also helped establish Mounjaro's clinical standing in the UK, which in turn supported private providers' pricing confidence. Understanding that context matters when you're comparing lists side by side.

What headline prices on comparison lists typically leave out

A figure quoted per pen or per month is rarely the whole story. Many headline prices exclude the consultation fee, which can be £20–£50 at some providers, charged separately before any medicine is issued. Prescription fees are sometimes additional. Delivery charges (particularly if tracked, refrigerated or next-working-day) can add £5–£15 per order. Aftercare and dose-review support, the kind of clinical oversight that actually keeps treatment safe, are sometimes sold as premium tiers.

None of that reflects poorly on any particular provider; it reflects how private pricing structures work. The practical lesson is to check what's covered before you compare two numbers. Our 5mg Mounjaro price breakdown walks through this in detail for patients moving to their first therapeutic dose, and similar detail applies at every rung of the schedule, for example, the picture shifts again at 10mg, where list prices are higher. If you want a closer look at what the larger 10ml format costs at that stage, our 10ml Mounjaro price page sets out the figures clearly.

It's also worth knowing that treatment begins at 2.5mg, a dose designed to help your system adjust before the prescriber moves you higher. The starter pen's job is tolerability, which is why patients often want clarity on what 2.5mg costs before committing to a longer plan.

Where nume sits in a price comparison, and why

Plainly: we are not the cheapest option on a Mounjaro price list. That's a deliberate choice, not an oversight. One transparent price covers the consultation, prescription, treatment, and free next-working-day DPD delivery to your door, order before 12pm on a weekday and your pen is dispatched the same day once the prescriber signs off, which is the sort of timing that matters if you fit treatment around picking the kids up. There are no add-ons to find at checkout, no monthly subscription locking you in, and no auto-renewal. Every repeat order is clinically re-reviewed from scratch.

A real human prescriber reads your consultation answers the same day (not software, not a template) and that's true whether you're starting at 7.5mg or requesting your first pen. Our clinical team and the wider service model are described openly on our about page if you want to read about the people behind the process. Current treatment pricing is shown on the treatment page; we don't print per-pen prices in body copy because they move as doses change and we'd rather you see the full picture once than a partial figure now.

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

For a prescription-only medicine (which Mounjaro is) the right question isn't which listing is lowest. It's whether the medicine is genuine, prescribed following a real clinical assessment, and supplied through the licensed UK supply chain. The MHRA has issued repeated public warnings about counterfeit weight-loss pens sold online: fake pens have contained insulin, have caused hospitalisations, and in 2025 the MHRA seized roughly 20 million doses of illegally traded weight-loss medicines with a street value of around £45 million. Reporting suspected fakes via the Yellow Card scheme is the fastest route to getting counterfeits off the market.

Red flags on any price list: a cost that sits dramatically below the current market range, no mention of a prescriber or clinical assessment, or discount codes attached to the medicine itself. Any pharmacy you buy from should appear on the GPhC register, which is publicly verifiable in seconds.
