Semaglutide Price Comparison: What UK Private Treatment Really Costs

What NICE and trial data say about semaglutide's value before you look at price

The price conversation starts to make more sense once you understand what the evidence says. In the STEP 1 trial, published in the New England Journal of Medicine, adults taking semaglutide 2.4mg alongside lifestyle changes lost an average of around 15% of their body weight over 68 weeks. That's the number behind the cost: a once-weekly injection, titrated gradually by a prescriber from a low starting dose, that works on GLP-1 receptors to reduce appetite and slow gastric emptying.

NICE recommended semaglutide for weight management under specific criteria (detailed in NICE technology appraisal TA875) including a requirement that it be used within a specialist service, for a maximum of two years, in adults with a BMI of 35 or above and at least one weight-related condition. That context matters when you're comparing prices privately, because the evidence base is dose-specific: the 2.4mg maintenance dose is what the trials tested. Treatment doesn't start there; it builds up through lower doses over several months, which is why monthly costs vary across the titration period. Understanding where you are in the schedule is part of why a genuine price comparison requires more than a single number, and if you want to understand which services offer the most competitive rates, our guide to the cheapest Wegovy provider breaks down what to look for across the market.

If you want to read about how the full titration pathway works, the 2.4mg cost context covers the maintenance-dose picture specifically.

What headline semaglutide prices usually leave out

A quick search for semaglutide prices will return a range of monthly figures. What those figures often exclude is worth listing plainly. Many providers charge separately for the initial consultation, sometimes £30 to £80 or more. Some add a prescription fee on top of that. Delivery charges vary, and some services charge for each dispatch. Aftercare (the clinical support you might need when side effects appear or a dose change is due) is sometimes billed separately or not offered at all.

That matters for a prescription medicine with a structured titration schedule. Semaglutide treatment doesn't begin at the maintenance dose; the UK pricing landscape for Wegovy reflects that costs shift month to month depending on which dose your prescriber has you on. A provider quoting only the starter-dose price can look considerably cheaper than one quoting an all-in maintenance figure, even if the actual total over six months is similar or higher once you add the extras.

The MHRA has also warned publicly about fake weight-loss pens circulating online and through social media. Prices that sit far below anything a licensed pharmacy can sustain, or sellers offering semaglutide without a prescription, are a clear warning sign, you can report suspect sellers through the Yellow Card scheme. Genuine semaglutide moves through the licensed UK supply chain; there is no shortcut that preserves safety.

Where nume sits in the semaglutide price picture, honestly

We are not the cheapest provider. That's deliberate. Our price is designed to be the only number you need: one figure that covers the consultation, the prescription, the medicine, and free next-working-day delivery. There are no separate fees layered on afterwards. If you want a sense of how that compares across the dose schedule, the full Wegovy price comparison list sets out the market context dose by dose.

Every consultation at nume is reviewed the same day by a GPhC-registered Independent Prescriber, a named clinician, not a decision algorithm. If you order before midday on a working day and your prescription is approved, your pen ships that afternoon and arrives with DPD the next working day. A lot of people find the 12pm cut-off useful to keep in mind; it's the kind of practical detail that makes the difference when you're trying to fit treatment into a normal week. You can read more about who we are and check our pharmacy's GPhC registration directly on the regulator's register at registration number 9012878.

We don't run discount codes, voucher promotions or seasonal offers. For a prescription medicine, the right comparison is clinical quality, verified identity checks, live weight confirmation, GP notification where appropriate, and a prescriber who reviews your record before every repeat. That's what a responsible price buys. If you're ready to take the next step, speak to our prescribers through our free consultation.

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

For most purchases, a lower price for the same thing is simply better. Semaglutide isn't that kind of purchase. It's a prescription-only medicine whose safe use depends on clinical assessment before treatment, correct storage in the cold chain, a licensed supply route, and ongoing prescriber oversight during titration. The NHS's own guidance on weight management injections is clear that these medicines should be used alongside structured support, not as a standalone product.

A seller who offers semaglutide without clinical assessment isn't providing the same product at a lower price, they're providing a different, riskier proposition. The MHRA's enforcement operations have seized large quantities of counterfeit weight-loss pens from unregulated sources; some contained wholly different substances. The right question isn't which provider is cheapest, but which one can show you a GPhC registration, confirm a named prescriber reviews your case, and trace your medicine to an authorised supply chain.

If you're weighing up your options and want to understand more about the broader treatment landscape, the weight-loss treatment overview covers what's licensed, how private access works, and what to ask any provider before committing. Or if you have questions about specific dose costs, the 1.7mg price context is one useful reference point mid-titration. Whatever your starting point, a free consultation with a prescriber is the right first move.
