Is there a cheaper alternative to Wegovy for weight loss in the UK?

How UK private pricing for weight-loss injections works

Private weight-loss treatments in the UK are priced per pen or per month, and the figure varies by medicine, dose, and provider. Neither Wegovy nor Mounjaro has a single fixed private price: the cost at the starting dose is materially different from the cost at the maintenance dose, and different pharmacies set their own margins.

For context, Eli Lilly raised Mounjaro's UK list price from 1 September 2025; reported private prices since then range roughly £149–£375 per month depending on dose and where you buy. Wegovy sits at a comparable range. These figures are widely reported and hedged here as such, actual prices at any given pharmacy should be confirmed directly. You can explore how Wegovy pricing works in the UK in more detail if that is your starting point.

The decision you are really making is not which medicine costs less on a comparison site, it is which medicine, at which dose, a prescriber considers appropriate for your health profile. Mounjaro and Wegovy work through different mechanisms: Mounjaro activates two gut-hormone pathways (GIP and GLP-1), while Wegovy targets the GLP-1 pathway alone. That distinction matters clinically. A prescriber weighing your options is not the same as a price filter on a search page.

If you want to understand whether Mounjaro might suit you better than Wegovy, a fuller comparison of licensed alternatives covers the evidence side by side.

What headline prices often leave out

A question our prescribers hear most weeks is: "I found it for less somewhere else, why?" The answer is almost always in what that lower price excludes. Many advertised per-pen prices do not include the initial consultation, the prescription fee, delivery, or any clinical follow-up. Add those line items and the apparent saving narrows quickly, sometimes disappears entirely.

Dose-review appointments, aftercare calls when side effects appear, and the clinical reassessment required before each repeat supply all carry a cost somewhere. Some providers absorb them into a subscription model; others charge as you go. Neither is inherently wrong, but the total cost across a full treatment course is the figure that matters, not the lead-in pen price.

There is also the question of what happens when something goes wrong. Nausea, changes in bowel habit, and injection-site reactions are common early in treatment, the full Wegovy information page outlines what to expect. If aftercare is not included, managing those early weeks costs something extra, in time if not in money.

For a grounded picture of what different providers charge and why the totals diverge, this guide on where to buy Wegovy in the UK works through the real comparison.

Where nume sits on price, and why

We are not the cheapest option for Wegovy or Mounjaro. That is a deliberate position. One price covers your consultation, the prescriber's review, your medicine, your prescription, delivery, and seven-day aftercare. Current treatment prices are listed on the treatment page, we do not bury them, and we do not add charges at checkout.

We do not run discount codes, promotional prices, or seasonal offers on prescription medicines. That is not a marketing position, it is a compliance one. These are POMs; attaching financial incentives to them raises serious regulatory concerns, and any seller offering vouchers or codes for Wegovy or Mounjaro is worth approaching with caution. Our clinical team and GPhC-registered pharmacy (registration number 9012878, verifiable at the GPhC register) underpin everything we do.

Why cheapest is the wrong benchmark for a prescription medicine

For most purchases, price is a reasonable proxy for value. For a prescription-only medicine that requires a cold supply chain, identity verification, and clinical oversight at every stage, it is not. The MHRA has warned publicly about counterfeit weight-loss pens sold without a prescription via social media and unregistered online sellers, in 2025 alone, approximately 20 million doses with an estimated street value of around £45 million were seized, and the first UK manufacturing site producing fake tirzepatide pens was raided. Fake pens have contained insulin instead of the labelled medicine.

The safe benchmark is not price, it is whether the pharmacy is on the GPhC register, whether a real prescriber reviews your case, and whether your medicine comes through a licensed UK supply chain. Eli Lilly and Novo Nordisk authorise specific wholesalers; a price far below the reported market range is a signal worth questioning, not celebrating.
