Cheapest weight loss injections on the NHS — and what private treatment actually costs

You looked up the NHS option first, here's where the waiting list actually stands

That's the right instinct. If you qualify for weight loss injections through the NHS, they come at no personal cost. The problem is qualifying. Under NICE's appraisal of tirzepatide (TA1026), NHS access to Mounjaro right now requires a BMI of 40 or above alongside four or more specific health conditions, high blood pressure, dyslipidaemia, obstructive sleep apnoea, cardiovascular disease, or type 2 diabetes. That threshold will drop over the coming phases, but the timeline stretches into 2027. Wegovy (semaglutide) is available through NHS specialist weight management services under separate NICE guidance, though waiting lists for those services are commonly long.

So for the majority of people searching today, the NHS route is either closed or far in the distance. That's not a criticism of the system, it's just the current reality, and being clear about it is more useful than glossing over it. If you want to understand the NHS eligibility criteria in more detail, the full breakdown of NHS weight loss injection costs and criteria covers what each phase requires.

Private prices: what a headline figure usually leaves out

Private treatment means paying for the medicine, and costs differ by dose and provider. To give you something concrete: Eli Lilly raised Mounjaro's UK list price from 1 September 2025, with reported private prices now ranging roughly £149 to £375 per month depending on dose and where you source it. Those figures are widely reported and worth knowing, but they're also where the fine print matters.

A quoted monthly price doesn't always include the consultation to get the prescription, the prescription fee itself, delivery, or any clinical support between doses. When you add those up, the cheapest-looking listing can stop looking cheap very quickly. It's also worth reading about how weight loss injection prices are structured on the NHS versus privately before comparing providers, because the starting points are genuinely different. Our frequently asked questions also address what a full private quote should contain.

What a transparent price actually includes, and where nume sits deliberately

We're not going to be the cheapest provider you find, and that's a considered choice. The reason is that we built a price that includes everything: the consultation, the prescription, the medicine, and free next-working-day tracked delivery by DPD in plain unbranded packaging. There's no consultation fee added at checkout, no prescription surcharge, no delivery tier to choose. Every repeat order goes through a fresh clinical review before dispatch, because a prescriber should check in before you move to a higher dose, not rubber-stamp the previous order.

Every consultation is personally read by a GPhC-registered Independent Prescriber, the same working day you submit it, with ID and live weight verification built into the process. You can verify our pharmacy on the GPhC register at any time, our registration number is 9012878. For anyone who wants to understand the cost picture across providers, this overview of cheapest weight loss injections in the UK sets out what to look for, and if you're specifically trying to find the cheapest weight loss injection available in the UK, that page also compares how different options sit on price. And if you're comparing injection options more broadly, our weight loss injections page explains both licensed treatments we offer.

Why cheapest is the wrong question for a prescription medicine

A prescription medicine isn't a commodity where the lowest price wins. The MHRA has warned publicly about counterfeit weight loss pens sold through social media and unverified websites, fake pens have contained the wrong substances entirely, and large seizures of counterfeit tirzepatide and semaglutide pens have taken place across the UK. The MHRA's Yellow Card scheme exists partly so that suspect sellers can be reported. A seller offering these medicines without a valid prescription and clinical assessment is a red flag, whatever the price.

The right questions are: is this pharmacy on the GPhC register? Does the price include everything, or will fees appear later? Will a real clinician review my health before prescribing? Order before midday and, once clinically approved, your treatment leaves our pharmacy the same day, arriving with DPD the next working day. If you're weighing results alongside cost, how much weight you can realistically lose is worth reading alongside the price comparison. And when you're ready to talk it through with our clinical team, start your free consultation, there's no fee just for finding out if you're suitable.
