Is Saxenda Cheaper Than Wegovy in the UK — and Does the Price Difference Matter?

You've searched this because Saxenda prices look lower, here's what that actually means

Picture this: you've seen Saxenda listed at a noticeably lower monthly price than Wegovy and you're wondering whether the cheaper option does the same job. It's a question our prescribers hear most weeks, and the honest answer starts with a licensing fact rather than a price comparison.

Saxenda is liraglutide, a GLP-1 receptor agonist made by Novo Nordisk. It is licensed in the UK for weight management. Wegovy is semaglutide, also made by Novo Nordisk, also licensed for weight management, but it works at a different dose, on a different injection schedule, and with a stronger body of evidence behind it. Saxenda is injected daily; Wegovy is once weekly. That daily frequency has a real cost implication: more frequent injections mean more pens consumed per month, which affects how providers price the course and how much you actually spend over time. A lower headline monthly figure for Saxenda can translate into comparable or higher spend across a full treatment period once you account for the full number of pens needed.

There is also a clinical context worth noting. The STEP 1 trial, published in the New England Journal of Medicine, found an average weight reduction of around 15% over 68 weeks with semaglutide 2.4mg. Published liraglutide trial data showed more modest average reductions, typically around 5–8% in trials of comparable duration. Neither figure is a guarantee for any individual, but when weighing two private price tags, it is reasonable to consider what the clinical evidence shows about each medicine's efficacy.

Saxenda is not a medicine that nume dispenses. This page exists to help you understand the comparison clearly, not to sell you a product.

What UK private prices for weight-loss injections typically do and don't include

When a clinic or online pharmacy quotes a monthly price for any injectable weight-loss medicine, it is worth treating that figure as a starting point rather than the total. The NHS's guidance on weight management injections sets out what a responsible private service should provide alongside the medicine itself: clinical oversight, lifestyle support, and ongoing monitoring. Not every provider bundles all of that into the advertised price.

Items that sometimes sit outside a headline price include the initial consultation fee, the prescription charge, delivery costs, and any clinical review fee for repeat prescriptions or dose increases. Add those up and a cheaper-looking Saxenda listing can end up costing more than a Wegovy quote that already includes them. Comparing injection-medicine prices without knowing exactly what each quote covers is a bit like comparing flights that show different baggage allowances, the number on the screen isn't the number at checkout.

What includes what at nume, and why we're not trying to be the cheapest

nume charges one price per treatment. That covers the consultation, the prescription, the medicine, delivery and ongoing clinical aftercare, nothing else to add at checkout. The exact figure is on the treatment page, because printing per-pen costs in editorial copy doesn't give you context; seeing the full package does.

We don't try to win on price. Cheapest isn't a race we entered. The reason is straightforward: a prescriber-led service with same-day clinical review, photo-ID and live weight verification, GPhC-registered pharmacy dispensing, and seven-day aftercare costs more to run than a service that doesn't do those things. We think that cost is worth carrying, and worth being transparent about.

What we do stock and prescribe for weight management is Wegovy (semaglutide) and Mounjaro (tirzepatide). Both are licensed in the UK for weight management. Both are reviewed by a real prescriber before every order, including repeats. If you'd like to understand which might be appropriate for you, our weight-loss overview covers both options, or you can read more about Wegovy specifically and how it works.

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

Saxenda and Wegovy are both prescription-only medicines under UK law. That means no legitimate supplier should offer either without a clinical assessment from a qualified prescriber, and any listing that appears to sidestep that requirement is a red flag, not a bargain.

The MHRA has issued repeated public warnings about counterfeit and illegally sold weight-loss injections. In 2025 alone, enforcement operations seized around 20 million doses of illegally traded weight-loss medicines, worth approximately £45m, and a site producing counterfeit tirzepatide pens was raided in Northampton. Fake pens have been found to contain insulin rather than the stated active ingredient, the consequences of injecting the wrong substance can be serious. If you're researching costs and want to understand whether Ozempic works out cheaper than Wegovy, that comparison is worth reading before you make any decisions based on price alone. You can verify any online pharmacy against the GPhC register at pharmacyregulation.org/registers; if a provider isn't there, don't order from them. Report suspect sellers via the MHRA Yellow Card scheme.

Price is not a meaningless consideration, but for a prescription medicine, the right question isn't which listing is cheapest. It's which service gives you genuine clinical assessment, confirmed supply-chain integrity, and proper support if something goes wrong.
