What is the Average Cost of Weight Loss Injections in the UK?

What the published price ranges are actually based on

The figures you'll find quoted across comparison sites and news articles reflect the UK private market as it has developed since NICE recommended tirzepatide in December 2024 (NICE Technology Appraisal TA1026) and following Eli Lilly's September 2025 list-price revision. At the time of writing, typical private prices for Mounjaro range from roughly £149 per month at the starter dose to around £330–£375 at the highest. Wegovy sits in a broadly similar band, though exact figures vary by provider and dose.

Both medicines are dosed on a gradual titration schedule, you begin on a lower dose while your body adjusts, then step up toward the maintenance dose over a period of months. That means the cost you pay in month one is almost certainly lower than the cost you'll pay at month six. Anyone comparing prices should be comparing the full treatment journey, not just the entry-level figure, and our guide to the price of weight loss injections walks through what that full picture tends to look like across different providers and doses.

These are not over-the-counter products. NHS guidance on tirzepatide sets out clearly that a prescriber reviews suitability, monitors response, and guides dosing. A legitimate price always reflects that clinical work, whether it's itemised or bundled.

What some headline prices quietly leave out

A low advertised figure can look appealing until you read what it covers. Common exclusions across the market include the consultation fee (sometimes charged separately per visit), the prescription fee, delivery charges (often per order, sometimes tiered by speed), and ongoing clinical support between doses. Some services charge additionally if a prescriber needs to review your records before approving a dose increase, or if you want to contact someone with a question mid-month.

The practical exercise takes under a minute: pull up a provider's checkout flow and add the items a real patient would need, consultation, prescription, delivery, one aftercare contact. That total is the number worth comparing, not the headline pen price. It's a useful habit, and it often changes the picture considerably.

For a broader breakdown of how different providers structure their fees, the weight loss injections cost guide covers the common pricing models in plain language.

Where nume sits in the market, and why

We are not the cheapest option, and that's a deliberate position. One transparent price covers your consultation, the prescription, the medicine, next-working-day DPD delivery, and 7-day access to our prescribers between orders. There are no add-ons, no subscription you have to remember to cancel, and no separate fee if our clinical team needs to review your notes before a dose change.

Every order is reviewed by a GPhC-registered Independent Prescriber before dispatch, a real clinician reads your consultation, not a rules engine. Our pharmacy is registered with the GPhC under premises number 9012878, which you can verify on the GPhC register directly. Medicines move through the licensed UK supply chain via authorised Eli Lilly and Novo Nordisk channels.

If you want to explore what treatment involves before making any decision, the weight loss injections overview covers how these medicines work, what the clinical trial evidence looks like, and what a supervised programme actually entails. Current treatment pricing is shown on the consultation and treatments page.

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

The MHRA has warned publicly about counterfeit weight-loss pens circulating online, including fake pens that have contained insulin rather than the labelled medicine. In October 2025, enforcement teams raided an illicit UK manufacturing site producing counterfeit tirzepatide pens, and earlier operations seized approximately 20 million doses of illegally traded weight-loss medicines with an estimated street value of around £45 million. The warning from the MHRA is consistent: the risk from unverified sources is not theoretical.

The red flags are recognisable. Sellers offering these medicines without a prior prescription, prices significantly below the market range, discount codes or voucher offers tied to a POM supply, none of these patterns are consistent with regulated UK pharmacy practice. A small monthly saving is not the measure that keeps you safe; the right question is whether the pharmacy is GPhC-registered, whether a qualified prescriber has reviewed your case, and whether the medicine has come through the authorised supply chain.

For readers thinking about what NHS access might look like as an alternative, the NHS weight loss injections cost page explains the current phased rollout and eligibility thresholds honestly. And if cost is a significant factor in your decision, including for those based in Northern Ireland who want to understand what local private providers charge, our breakdown of weight loss injections Belfast price information sits alongside the guide to lower-cost weight loss injection options, which sets out the realistic options within the regulated market without overpromising.
