My BMI, Wegovy, and What That Means for the Price

Step 1: Your BMI opens the door, but your prescriber decides

A lot of people arrive at this question assuming their BMI will determine a specific price tier, like a tariff. That's a reasonable guess, but it's not how it works. BMI is a threshold, not a pricing variable. Wegovy (semaglutide) is licensed in the UK for adults with a BMI of 30 or above, or from 27 if you have at least one weight-related condition such as high blood pressure, type 2 diabetes or high cholesterol. Lower BMI thresholds apply for some ethnic backgrounds under UK clinical guidance. Once you clear that threshold, a GPhC-registered prescriber reviews your health in full (your weight, your history, any medications, your circumstances) and decides whether Wegovy is clinically appropriate for you. Wegovy's full eligibility picture is worth reading before you book anything. The NICE appraisal of semaglutide for weight management sets out the conditions framework clearly, and NICE TA875 is the published source if you want the detail.

The prescriber also sets your starting dose. Everyone begins at 0.25mg and titrates upward over several months, and if you want to understand what each stage costs as you move up, you can read about the wegovy 1mg price as an example of how mid-titration costs sit in the market. That matters for cost because different dose pens carry different prices across the market.

Step 2: Understanding what private Wegovy actually costs, and why figures vary

Private pricing for Wegovy in the UK is set by each provider independently and reflects the dose pen, the clinical service wrapped around it, and supply chain costs. Market figures reported since late 2025 suggest monthly costs somewhere in the £149 to £375 range across providers, varying by dose. Those numbers are hedged deliberately: they move, and they differ depending on what's included.

That last word (included) is where things get murky. Headline prices advertised by some providers cover only the medicine itself. Consultation fees, prescription charges, delivery costs and any clinical support after your first order can each be added on top. Before comparing prices, it's worth asking the same question of every provider: what is not in that number? A detailed breakdown of how Wegovy costs are structured can help you read the market more clearly. The NHS medicines page for semaglutide also gives useful background on the medicine itself, independent of any provider's pricing.

One thing worth stating plainly: there is no such thing as a discount code for a prescription medicine from a verified, regulated UK pharmacy. If a seller is offering promo codes or heavily reduced prices for Wegovy, that is a reason to pause, not a reason to click.

Step 3: What the nume price actually includes

nume's position on price is straightforward, and we'll say it directly: we are not the cheapest option you will find. That is a deliberate choice. One price covers your consultation, the prescription, the medicine itself, free next-working-day delivery by DPD, and clinical support seven days a week. There is no subscription. Every repeat order is clinically reviewed again by a real prescriber (not routed through software) before anything is dispensed, and our guide to wegovy pen pricing explains how individual pen costs feed into what you pay at each stage. The story behind nume and the clinical team who oversee prescribing are both on the site if you want to read them.

Current treatment pricing is listed on the treatment page, which is where we keep it current rather than in body copy that can date. We don't print per-pen figures here because they can shift, and we'd rather you see the live number than a stale one.

Step 4: Why 'cheapest' is the wrong question for a prescription medicine

Here is the honest close. Wegovy is a prescription-only medicine. The MHRA has documented seizures of approximately 20 million doses of illegally traded weight-loss medicines, with counterfeit pens containing entirely wrong substances, including insulin, causing hospitalisations. You can read the MHRA's Yellow Card reporting system and check any online pharmacy on the GPhC register, both take under two minutes. Price is a reasonable thing to compare once you have verified that a provider is registered, genuinely prescribing, dispensing from a licensed UK pharmacy, and has clinical oversight in place, and for those who have reached the highest maintenance dose, our page on the wegovy 5mg price sets out what that looks like in context. Before that verification step, the cheapest listing answers the wrong question entirely.

If your BMI meets the licensed threshold and you'd like a prescriber to review whether Wegovy is right for you, the consultation at nume is free. No commitment, no obligation.
