How Much Does It Cost to Get Weight Loss Injections?

Where the published price figures come from

The £149–£375/month range that gets quoted most often reflects the UK private market after Eli Lilly raised Mounjaro's list price from 1 September 2025, the highest-dose pen moved from around £122 to roughly £330 in list terms, as widely reported. Providers set their own prices on top of that wholesale cost, so what you see advertised varies considerably by dose and clinic. Semaglutide (Wegovy) sits in a similar band. NICE's appraisal of tirzepatide, published as TA1026 in December 2024, gives a useful picture of the clinical evidence behind these medicines without touching private pricing, it is worth reading alongside any cost comparison.

One thing those headline numbers share: they represent a single pen or a single month's supply. A starting dose costs less than a maintenance dose, so monthly spend typically rises as treatment progresses. If you are comparing providers, the starting price is rarely what you will pay after month two or three.

The lower the dose the lower the monthly figure, which is fine to note, but the full cost picture across a course of treatment looks quite different from the entry-level figure.

What headline prices frequently leave out

A price shown for the medicine alone often excludes some or all of the following: an initial consultation fee, the prescription charge, delivery costs, and any support if you have questions between doses. Add those up across several months and the gap between a low headline and a genuinely all-in price closes quickly, sometimes reverses.

It is worth asking any provider a blunt question: does this price include the clinical consultation, the prescription, delivery and access to a prescriber if something goes wrong? If the answer is yes to all four, compare on that basis. If not, do the arithmetic. If you want a clearer sense of how much it is for weight loss injections once all those components are counted in, that page works through the moving parts in detail. The breakdown of what drives the total monthly cost covers this in more detail.

These medicines are licensed for weight management alongside a reduced-calorie diet and increased physical activity, as confirmed in NHS England's guidance on weight-management injections. That means clinical oversight across the course of treatment is not optional, it is part of what legitimate private care includes.

How nume prices treatment, and why we are not the cheapest

We are not going to win a price comparison. That is a deliberate choice. One price at nume covers your consultation, your prescription, the medicine, next-working-day tracked delivery and seven-day aftercare, nothing added at checkout. No subscription renews automatically in the background. Before every repeat, a prescriber reviews your progress. If you want a straightforward answer to how much weight loss injections are before you commit to anything, that page sets out current figures by dose. If you are looking for the lowest possible number, you will find a lower one elsewhere. If you are looking for a number that does not change shape when you look closely, we think our approach is worth understanding first.

Current treatment pricing is shown on our treatment page. We do not print per-pen prices in editorial copy because prices move with dose, and the dose that suits you is a clinical determination, not something you should pick from a price list.

If you have seen discount codes attached to weight loss injection listings online, that is worth pausing on. nume does not run discount codes, sorry, to be clear: nume does not run discount codes, vouchers or promotional offers on prescription medicines. Discount codes attached to Prescription-Only Medicines from unverified sellers are a genuine red flag. The MHRA has warned publicly that fake pens have been seized in large numbers from illegal supply chains, some containing dangerous substances. Report any suspect seller at the MHRA's Yellow Card service.

Why the cheapest option is the wrong way to shop for a POM

Prescription-only medicines require a registered prescriber and a regulated pharmacy. There is no legal route to these injections without a clinical assessment, a seller offering them without one is operating outside UK law, regardless of how the listing is phrased. The question worth asking is not "who is cheapest" but "who has verified my identity, confirmed my weight, checked my medical history and is accountable if something goes wrong".

You can verify any online pharmacy against the GPhC register at pharmacyregulation.org/registers. nume's GPhC premises registration is 9012878. For more background on accessing these medicines safely, this page addresses cheap-injection searches specifically, including what safety shortcuts actually look like in practice.

Weight loss injections can be a meaningful clinical intervention for eligible adults. Getting the right supply, from a legitimate source, reviewed by a real prescriber, is what makes the difference. If the cost of doing that properly is a concern, it helps to understand what the cheapest weight loss injections actually involve before making a decision, because the lowest price and the lowest risk are rarely the same thing. Speak to our prescribers, there is no charge to find out whether treatment is suitable for you.
