How much is weight loss injections in the UK — and what does the price actually cover?

You've found a price online. Here's what to check before comparing it to anything else

A lot of people searching for how much weight loss injections cost find a headline figure and assume that's the total. It often isn't. Many private providers quote the medicine alone and add a consultation fee on top, sometimes £30–£60 per visit. Others charge separately for the prescription, for delivery (which may not be tracked or temperature-controlled), or for access to a prescriber if a problem comes up mid-treatment. Those costs are real, even when the advertised price doesn't show them.

A question our prescribers hear most weeks is some version of: "I saw a cheaper price elsewhere, why is yours different?" The honest answer is that the price reflects what's wrapped around the medicine. At nume, one figure covers the consultation, the prescription written by a named clinician, the treatment, free next-working-day DPD delivery, and ongoing aftercare seven days a week. There are no separate line items. When you're comparing providers, it's worth adding up what each one actually includes before deciding which is cheaper.

Wegovy (semaglutide) and Mounjaro (tirzepatide) are both licensed for weight management in the UK, and both are available through private prescriptions for adults who meet the clinical criteria. If you're wondering how much the weight loss injection is and what drives the price differences between options, our dedicated page walks through what you can expect to pay and why. You can also read a fuller breakdown of how pricing differs between medicines on our page about how much weight loss injections cost by treatment type.

Why the dose you're on changes how much you pay each month

Weight loss injections are not a fixed monthly cost. Both Mounjaro and Wegovy start at a low dose (a tolerability level designed to let your body adjust) and the prescriber increases it gradually over weeks. Higher doses generally cost more per pen, so your monthly spend tends to rise as treatment progresses. This is not a hidden charge; it's a consequence of the prescribing schedule, and any transparent provider should explain it upfront.

For Mounjaro, the licensed UK strengths run from 2.5mg through to 15mg, titrated in stages. For Wegovy, the standard pathway runs from 0.25mg up to 2.4mg weekly, with the newer 7.2mg pen approved by the MHRA in April 2026 now offering a higher maintenance option. The weight loss injections overview page covers how each medicine works and what the dose pathway looks like in practice.

If you're thinking about the longer-term cost, NICE's appraisal of tirzepatide (TA1026, published December 2024) sets out the clinical evidence base and the NHS eligibility criteria, which are stricter than private ones. For people who don't meet those criteria or prefer not to wait, a regulated private route is the practical alternative. Our guide to weight loss injections and how much they cost covers what to budget for across different medicines and dose stages, with detailed cost context by dose also available on our dedicated cost breakdown page.

Where nume fits in the market, and why cheapest isn't our goal

We price to cover everything properly. That means we are not at the low end of the market, and we're not pretending otherwise. Clinical corners are easy to cut when you're trying to win on price, skipping video weight verification, skipping the GP notification, skipping the individual prescriber review in favour of an algorithm. Those shortcuts are what allow some providers to quote lower figures. None of them happen at nume.

Every consultation is reviewed personally by a GPhC-registered Independent Prescriber, the same day you submit it. Before any dose increase, you'll need to provide evidence of your current weight and treatment history. Our pharmacy holds GPhC premises registration 9012878, you can verify that at the GPhC register. Medicines are sourced through the licensed UK supply chain. If you order before noon on a working day and your prescription is approved, treatment ships that afternoon and arrives the next working day.

Current treatment pricing is listed on our treatments page, alongside the consultation form. The about us page explains who we are and how the service is structured, and our clinical team profile shows who oversees prescribing.

The cheapest option is the wrong thing to optimise for when a prescription medicine is involved

There is a real risk attached to low prices for these medicines. The MHRA has seized approximately 20 million doses of illegally traded weight loss medicines (around £45 million in street value) and, in October 2025, raided the first illicit UK site producing counterfeit tirzepatide pens, in Northampton. Fake pens have in some cases contained insulin rather than the labelled medicine, causing hospitalisations. The MHRA's advice is clear: these medicines must come from a pharmacy you can verify on the GPhC register, issued on a legitimate prescription following a clinical assessment.

Sellers offering these medicines without a prescription, or promoting dramatic discount codes with no verifiable clinical oversight, are a red flag. For a Prescription-Only Medicine, the correct question is not "which provider is cheapest?" but "which provider can I verify, and what clinical process do I get?" If you want to understand more about how to tell a safe provider from an unsafe one, our guide to cheap weight loss injection offers works through the warning signs in detail. You can also report suspect sellers directly through the MHRA's Yellow Card scheme.
