Semaglutide BNF price and what UK private treatment really costs

What the BNF tells you about semaglutide pricing, and what it doesn't

The British National Formulary is written for prescribers and pharmacists, not for patients comparing private options. It records the medicine's licensed status and clinical parameters; it is not a price-comparison tool for private supply. Semaglutide (Wegovy) appears there as a weight-management prescription medicine licensed for adults with a BMI of 30 or above, or from 27 with a weight-related condition such as high blood pressure or type 2 diabetes. The BNF's semaglutide entry is a useful professional reference for clinical detail, but headline private costs are set by the pharmacy or clinic, not recorded there. For a grounded sense of what the UK market looks like, the more useful question is what a quoted price actually covers.

Eli Lilly's September 2025 list-price increase for Mounjaro brought wider attention to how quickly supply costs can shift; Novo Nordisk's pricing has followed comparable market dynamics. Reported private semaglutide prices range roughly from £149 to over £300 per month depending on dose and provider, though those figures are hedged and move. The dose you are on matters significantly to cost, and you can see a detailed look at how each pen is priced on our semaglutide pen price page, because the higher pens used for maintenance are priced differently to the starter pen.

What headline semaglutide prices usually leave out

A quoted monthly cost for semaglutide can look clean on screen and turn out to be incomplete. Common exclusions include the initial consultation fee, charged separately by many clinics; a prescription fee on top of the medicine price; delivery, which at tracked next-day courier rates adds up across a year; and aftercare, the ongoing clinical support that should accompany any prescribing of a prescription-only medicine like semaglutide. Some services also charge for dose-review appointments each time you move up the titration schedule.

There is also the question of what happens when something goes wrong. A side effect, a missed pen in the post, a question at 7pm on a Sunday, those moments reveal whether a cheap monthly price came with clinical backup or just a box in the mail. Aftercare is not a nice-to-have for a medicine that works by suppressing appetite; it is the infrastructure that keeps the treatment safe. When you see a low headline number, it is worth adding up every line item before comparing.

Where nume sits on price, and why, deliberately

One transparent price at nume covers the consultation, the prescription, the medicine, tracked next-working-day DPD delivery, and 7-day priority aftercare. Nothing is invoiced separately. We don't run discount codes, seasonal promotions or vouchers; our current treatment pricing is listed on the treatment page. We are not the cheapest option on the market, that is a deliberate choice, not an oversight.

The clinical infrastructure behind each order is the reason. Every repeat is re-reviewed before dispatch. Every consultation is read by a real prescriber (a named GPhC-registered Independent Prescriber, same day) before any medicine moves. Identity is verified. Weight is confirmed on video. If you are transferring from another provider, we check the evidence. Our clinical team treats this as medicine, not retail. That takes resource, and it shows in the price. You can verify our pharmacy's GPhC registration directly at GPhC registration 9012878.

If the all-in figure matters to you, our Wegovy price page explains exactly what is included and where the cost sits relative to the market.

Why price is the wrong test for a prescription medicine

Semaglutide is a prescription-only medicine. The MHRA has issued repeated warnings (backed by enforcement action) about fake weight-loss pens sold online without clinical oversight. Counterfeit pens seized in the UK have contained incorrect or dangerous substances; the MHRA's guidance on reporting suspect sellers via Yellow Card exists precisely because this market attracts bad actors drawn by high demand and high price points.

A very low price from an unverified seller is a red flag, not a deal. Sellers offering these medicines without a prescription and without any clinical assessment of your medical history are operating outside UK law. The safety question (is this genuine medicine, prescribed correctly, for my specific situation) is worth more than any saving on the monthly cost. Before you order from any online pharmacy, check it against the GPhC register. If it is not there, do not order. Full stop.
