How Much Does It Cost for Weight Loss Injections in the UK?

What official guidance says about how these medicines are priced

NICE recommended tirzepatide (Mounjaro) for weight management in December 2024, and its appraisal (TA1026, published on the NICE website) makes clear that treatment is expected to sit within a structured clinical pathway. That context matters when reading a price: tirzepatide and semaglutide (Wegovy) are not supplements or lifestyle products. They are regulated prescription medicines, and their pricing in the private market reflects the supply chain, the prescribing work and the pharmacy dispensing, not just the physical pen.

Eli Lilly's published UK list price for Mounjaro rose sharply from 1 September 2025. The 2.5mg and 5mg pens sit at the lower end; the 15mg pen carries a list price of around £330 per four-week supply, as widely reported at the time. Private providers price above or around that figure depending on what their service includes. Wegovy (semaglutide) pricing follows a similar structure, with doses from 0.25mg through to the newer 7.2mg pen approved by the MHRA in April 2026. If you are trying to work out how much weight loss injections are likely to cost you at each stage of titration, the published range across private providers is broadly £149–£375 per month by dose, hedged because individual services price differently.

Spending time comparing headline figures without knowing what each one includes is a common source of confusion. The figure at the top of a product listing is not always the figure you pay, and it rarely tells you what happens if you need clinical support after your first pen arrives.

What headline prices often leave out

A low monthly figure can look appealing. It sometimes is genuinely all-in. Often, though, it covers the medicine alone — with consultation fees, prescription charges, delivery costs and any clinical support priced separately, or not available at all.

A few things worth checking before committing to any provider: whether the clinical consultation is included or charged as an add-on; whether there is a prescription fee on top; whether delivery is free or cost-per-order; and what happens if you need advice between doses. Some services charge for dose-review appointments. Others operate on a subscription model where your treatment renews automatically unless you actively cancel. Those structures are not necessarily wrong, but they change the real monthly cost considerably. For a fuller look at how these figures stack up, our breakdown of what weight-loss injections cost walks through the components in more detail.

There is also a meaningful difference between a provider that re-reviews your case clinically before each repeat, and one that processes repeats as a transaction. If you want a clear answer to how much it costs to get weight loss injections when you factor in consultation, prescription and delivery fees, the total can look quite different from the headline medicine price. For a medicine that is titrated over months and that requires monitoring, those are not equivalent services even if the price looks similar on a comparison page.

Where nume sits on price, and why

A prescriber at a reputable clinic once told a patient something that stuck: the wrong question is "what's the cheapest option?" The right question is "what does this service do if something goes wrong at week three?" We think that framing is fair.

At nume, one transparent price covers the free consultation, the prescription, the medicine, free next-working-day DPD delivery and priority aftercare seven days a week. There is no subscription, no auto-renewal and no separate delivery charge. Every repeat order is reviewed by a real clinician before it goes out. A named GPhC-registered Independent Prescriber reads your consultation answers (a human, not a system) and approves or declines based on clinical judgement.

We are not the cheapest option on the market. That is a deliberate choice: clinical infrastructure, genuine supply-chain relationships with Eli Lilly and Novo Nordisk, photo-ID verification, live weight checks on video and GP notification all cost something to run properly. Our about page explains the pharmacy and prescribing model in more detail, and you can verify our GPhC-registered pharmacy directly at the GPhC register (premises number 9012878). If current treatment pricing is what you need, it's listed clearly on the treatments page, no hidden steps.

Why cheapest is the wrong test for a prescription medicine

The MHRA has warned repeatedly about counterfeit weight-loss pens sold through social media and unverified online sellers, pens with no clinical oversight, no verified supply chain and, in some cases, contents that have caused serious harm. In late 2025 the MHRA raided the first illicit UK manufacturing site producing counterfeit tirzepatide pens. Prices far below the market range, offers made without a clinical consultation and sellers with no verifiable GPhC registration are the consistent red flags. You can report a suspected seller through the MHRA's Yellow Card scheme, which handles both side-effect reports and suspect product reports.

For any prescription medicine, price is not the primary quality signal. The questions that actually protect you are: is the pharmacy GPhC-registered and verifiable? Is a qualified prescriber reviewing my case individually? Is the medicine coming from the licensed UK supply chain? People often ask how much the weight loss injection is per pen, but a small saving against a reputable provider is not the measure that keeps you safe. If you want to understand the full landscape of what 'cheapest' actually means for these medicines, or want a detailed look at how much weight loss injections cost across the range of doses and providers, our weight-loss treatment overview is a good place to start before speaking to a prescriber.
