How much water should you drink on semaglutide — and what does it cost to get started?

The honest answer about UK private pricing for semaglutide

UK private pricing for weight-management semaglutide (Wegovy) is not fixed. It varies by dose, by provider and by what is bundled in. Since Eli Lilly's price increase for tirzepatide in late 2025 drew wider attention to the market, Wegovy has also been widely discussed in the same breath, and the monthly figures people see online range from roughly £149 to well over £300, depending on the dose and the clinic. Those are real market figures, reported across the sector, but they shift. For a more grounded look at current treatment costs, the Wegovy price page sets out what you should expect to pay and why.

One variable that often surprises people is that the starting dose (0.25mg) costs less than the maintenance doses, so quoted monthly prices are sometimes for the lowest rung of a titration schedule that ends considerably higher. Anyone budgeting for treatment should think across several months, not just week one. It is also worth thinking about practical daily habits during treatment, and our guide covering how much water to drink on Wegovy is a useful starting point for understanding what good hydration looks like alongside your doses.

What headline prices often leave out

A low headline price for semaglutide frequently excludes things you will need regardless. Consultation fees are common, some providers charge £20 to £50 or more per review. Prescription fees may be added separately. Delivery charges can appear at checkout. Dose-change reviews, follow-up support and aftercare calls are sometimes billed as extras or absorbed into a monthly subscription that renews automatically.

This matters practically. If you order on a Friday payday and your pen doesn't arrive until Tuesday because same-day dispatch wasn't included, that is a gap in treatment that has clinical implications. Speed and continuity are part of the service, not a luxury. Staying well hydrated throughout treatment is one of the factors that affects how you feel day to day, and our page on how much water to drink on semaglutide covers the practical guidance in full.

Our frequently asked questions cover what the consultation process involves and how repeat orders work, which is worth reading before you compare providers.

Where nume sits in the market, deliberately

We are not competing to be the lowest-priced option. That is a considered choice, not an oversight. One transparent price covers your consultation, the prescription, the treatment itself and free next-working-day delivery. There are no subscriptions, no auto-renewals and no aftercare charged separately. What you see is what you pay. A real clinician (a named, GPhC-registered prescriber, not an automated system) reads your consultation answers before anything is approved or dispatched. The about us page explains the clinical infrastructure behind that.

You can verify our GPhC-registered pharmacy on the official register at GPhC registration number 9012878. We think that kind of transparency is table stakes for a service dispensing prescription medicines.

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

Semaglutide is a Prescription-Only Medicine. That legal classification exists because the clinical risk (pancreatitis, dehydration, interactions with other medicines, contraindication in certain conditions) is real enough to require a qualified prescriber to assess you individually before treatment begins. Dehydration in particular is something patients ask about frequently, and if you want specific guidance our page on how much water you should drink while on Wegovy addresses the question in detail, as does our separate page covering how much water you should drink on Wegovy for those who prefer a slightly different framing. The MHRA has seized counterfeit weight-loss pens from unverified online sellers and recorded hospitalisations linked to fake products; their Yellow Card reporting scheme is where suspected counterfeits and adverse reactions can both be reported.

A seller offering semaglutide without a clinical assessment beforehand, or with prices far below the market range, is a red flag. The question for a prescription medicine is not which provider is cheapest, it is which provider can demonstrate a licensed supply chain, a qualified prescriber and the clinical oversight to keep you safe throughout treatment. For further reading, the NHS semaglutide medicines page and NICE's appraisal of Wegovy (TA875) set out what responsible clinical use looks like.

If you're ready to see whether semaglutide is clinically suitable for you, the Wegovy injection pricing page gives more detail on costs, and you can check your eligibility through a free consultation with our prescribers, reviewed the same day, with no obligation to proceed.
