How much semaglutide to inject for weight loss — and what it actually costs in the UK

What does semaglutide for weight loss cost in the UK right now?

Semaglutide (sold as Wegovy) is a prescription-only medicine, so every legitimate supply comes with a prescriber's assessment built in. Private pricing reflects that. Since Eli Lilly's well-reported list-price increase in September 2025, the broader market for injectable weight-loss medicines has shifted, and typical monthly costs for Wegovy now range roughly £149 to £375 depending on the dose and the provider, figures that have been widely reported and vary between services. The dose you're on matters: someone titrating through the early stages pays a different rate than someone stabilised at 2.4 mg or the newer 7.2 mg maintenance dose, which the MHRA approved as a dedicated single-dose pen in April 2026.

One thing worth knowing: the injection schedule (0.25 mg rising over several months to 2.4 mg, and potentially 7.2 mg) means your costs are likely to change as your dose does. A quote for the starting dose isn't a quote for the full course. If you want to understand how much semaglutide to take for weight loss at each stage of the titration ladder, our dedicated guide covers how doses are structured and what that means for your costs over time. The full Wegovy pricing page gives more context on how costs shift across the titration ladder, and if you're looking to reduce what you spend, our page on wegovy coupons explains the saving options currently available.

Semaglutide is a prescription-only medicine under UK law, and the MHRA regulates its supply, for more on the licensed indications and safety profile, the NHS semaglutide page is the clearest patient-level reference available.

What do headline prices typically leave out?

This is where it gets easy to make a bad comparison. A headline monthly price sometimes covers the pen alone. Consultation fees, prescription charges, delivery and any dose-review support can all sit outside that figure, added at checkout or, worse, only visible when you need them.

Some services charge separately for each of these. Others bundle a few but not all. It's worth asking specifically: is a clinical review included before every repeat? Is aftercare covered if you have a question mid-month? Is delivery free at every dose, or only at the starter?

The misconception that the cheapest listing is the simplest option is one that catches a lot of people out. A lower headline number can quietly become a higher total once prescription fees, delivery and support costs are added back in. Worth doing the arithmetic before assuming anything. Our semaglutide cost guide walks through what a fair, all-in price should cover.

Where does nume sit on price, and why?

Honestly, not at the bottom. We don't enter the race for the lowest number, and that's a deliberate choice. One transparent price at nume covers everything: the clinical consultation, the prescription, the treatment, free next-working-day DPD delivery, and priority aftercare seven days a week. No subscription. No auto-renewal. Every repeat order gets a fresh clinical review before it goes anywhere.

Our prescribers (all GPhC-registered Independent Prescribers) review every consultation personally. You can see who oversees our clinical team on the clinical team page. For anyone transferring from another provider or requesting a dose increase, we check the evidence before approving. That process takes a little more care than a click-through system, and it should.

Current treatment pricing is shown on the treatment page; we don't publish per-pen prices in page copy because they shift with dose and supply. What doesn't shift is what's included.

Is 'cheapest' the right question to ask about a prescription medicine?

For most purchases, price is a reasonable proxy for value. For a prescription-only medicine injected weekly, it's the wrong test. The MHRA has issued repeated warnings about fake weight-loss pens sold online, some containing insulin rather than semaglutide, with users hospitalised as a result. Counterfeit seizures in 2025 ran to approximately 20 million doses with an estimated street value of around £45 million. Sellers offering these medicines without a prior clinical assessment or at prices far below the market rate are a red flag, not a bargain.

Verifying that a pharmacy is properly registered takes about thirty seconds: the GPhC register lists every legitimate UK pharmacy premises. nume's registration number is 9012878, verifiable directly on that register. If a seller isn't on the list, walk away.

For anyone weighing up results alongside costs, our page on how much weight loss to expect per month on semaglutide covers what the trial evidence actually shows, hedged correctly, with citations. If you're also unsure about the practicalities of using the pen correctly, our guide on how much semaglutide you should inject explains what to expect at each dose step. The short answer is that results vary, and clinical supervision through the process is part of how you get the best outcome from the medicine.
