How much does semaglutide cost per month in the UK?

You've found a price online. Here's what to check before you trust it.

Picture the situation: you've searched, found a few providers, and you're looking at a row of monthly figures. Some feel reasonable. One looks surprisingly low. The instinct is to compare them as if they're the same thing, but they rarely are.

Private semaglutide pricing in the UK is set per pen, and each pen covers four weekly doses. The dose you're on determines the pen strength, and the pen strength largely drives the monthly cost. If you want a clear picture before you start, it's worth reading through how much semaglutide costs at each stage of treatment, since the figure changes meaningfully as your dose increases. Since Eli Lilly's Mounjaro price revision in autumn 2025, the broader injectable weight-loss market has seen upward pressure across providers; Novo Nordisk's own pricing position for Wegovy has also shifted during this period, and it's worth understanding the current landscape before committing.

The NHS describes semaglutide's role in weight management and what a clinically appropriate supply looks like on its patient information pages for semaglutide, a useful read before you engage with any provider.

What the headline price often leaves out

This is the part that catches people. A monthly figure on a website might include the pen and nothing else. The consultation (a mandatory clinical step) can be charged separately, sometimes as a recurring fee at every repeat. The prescription itself is sometimes added at checkout. Delivery, which for a refrigerated injectable is a non-trivial logistics question, may be priced on top. And aftercare (the ability to speak to someone if you feel unwell, if your dose needs reviewing, or if something just doesn't feel right) is sometimes absent entirely or locked behind a premium tier.

If you're comparing prices across providers, the honest comparison looks at the total you'd pay for treatment, consultation, prescription, delivery, and ongoing clinical support. Add those up for each provider and the picture changes. A fuller breakdown of how semaglutide's monthly costs stack up across the UK market can help with that exercise.

One practical aside: a lot of people time their first order around payday, or place it on a Monday so it arrives before the week gets going. If you're ordering before a bank holiday, it's worth checking the provider's dispatch schedule, next-working-day delivery means exactly that, and a Friday order before a long weekend may arrive on Tuesday.

What nume's price includes, and why we're not competing on being cheapest

At nume, the price you see on the treatment page is the price you pay. It covers your consultation, the prescription, the medicine, and free next-working-day DPD delivery to your door. There's no subscription. Every repeat order goes through a fresh clinical review before anything is dispatched. Aftercare is available seven days a week. Nothing is added at checkout.

We're not the cheapest option on the market, and that's a deliberate choice. The infrastructure behind a safe supply (a GPhC-registered pharmacy with a premises number you can verify at the Pharmacy Register, photo-ID verification, live weight checks on video, GP notification in line with GPhC guidance) costs money to run properly. We'd rather be transparent about that than compete on a headline figure that obscures what's actually included.

Our prescribers are GPhC-registered Independent Prescribers. Our clinical team reviews every consultation personally, the same day it's submitted. If treatment isn't appropriate, we say so. That's the service the price is paying for.

Why 'cheapest' is the wrong question to ask about a prescription medicine

Wegovy is a prescription-only medicine. Under UK law, it can only be legally supplied following a clinical assessment by a qualified prescriber. That means any legitimate provider (NHS or private) is required to include that step. A price that looks unusually low may be low because something has been removed: the clinical review, the genuine supply chain, or both.

The MHRA has issued repeated warnings about counterfeit and illegally traded weight-loss injectables, including seizures of fake pens that have contained insulin instead of semaglutide. Its guidance on reporting suspect sellers via the Yellow Card scheme is worth bookmarking. Red flags include sellers offering these medicines without a prescription, prices well below the private market range, and discount codes from sources you can't verify.

NICE's appraisal of semaglutide for weight management (NICE TA875) sets out the clinical framework that supports appropriate prescribing. The right question to ask of any provider isn't whether their price is the lowest. It's whether the supply is genuine, the clinical review is real, and the aftercare is there if you need it. Those are the measures worth comparing, and if you're specifically budgeting for Wegovy, a detailed look at how much Wegovy costs per month across UK providers will give you the figures you need alongside a direct comparison of Wegovy pricing across UK providers.
