How much do weight loss injections cost in the UK?
By Pick My Pharmacy Editorial · Updated 9 July 2026
What private weight loss injections cost per month
Weight loss injections are sold privately as a monthly treatment service, and the price depends on which medicine you are prescribed and what dose you are on. Wegovy (semaglutide) typically costs £120–£300 a month, Mounjaro (tirzepatide) £130–£330, and Saxenda (liraglutide) £120–£200. The spread within each range reflects dose: these medicines are started low and increased gradually over several months, so a starter dose sits at the bottom of the range and the full maintenance dose at the top. Expect your monthly cost to rise as your dose steps up — that is normal titration, not a hidden price increase. Because prices vary between pharmacies for the same medicine and dose, comparing total monthly cost across providers is worthwhile before you start. Ranges are editorial market research — always confirm live prices.
Illustrative year-one / pathway cost
A realistic private budget is pathway cost, not month one. Using our published dose-tier ranges across GPhC-registered UK online pharmacies: if you titrate over several months then spend much of the year near maintenance, Wegovy often illustrates around £1,800–£3,000+ in year one; Mounjaro around £2,000–£3,600+ depending how quickly you reach 10–15mg; Saxenda around £1,400–£2,400+ as daily dosing uses more pens at higher doses. Someone who stops early, pauses, or stays on a mid-tier dose will spend less. These figures are illustrative ranges across providers — not Live Well or any single clinic’s price list — and they assume consultation approval and ongoing supply. Confirm inclusions and current checkout prices before you commit.
What the monthly price includes
At most regulated online pharmacies the headline monthly price is an all-in service fee covering the prescriber consultation, the medicine (a pre-filled injection pen), and tracked delivery. Needles and wipes are often included for weekly pens; ask whether a sharps bin is supplied or only disposal advice is given, and whether cold-chain packaging is used where required. A small number of providers price the consultation or delivery separately, which can make a low headline price misleading. When comparing, look at the total cost for your dose per month, and check whether ongoing dose reviews during titration are bundled. See our answer on what is included in an online pharmacy treatment price for a full checklist.
Who can be prescribed weight loss injections
Weight loss injections are prescription-only medicines, so every legitimate service — online or in person — requires a consultation before supply. Private prescribers typically apply BMI-based criteria drawn from the medicines' licences: broadly, a BMI of 30 or above, or a lower threshold (around 27) where you have a weight-related health condition such as type 2 diabetes, high blood pressure, or sleep apnoea. NHS criteria are often stricter and, for tirzepatide, phased by cohort — NICE-eligible does not mean automatic NHS access. Expect to provide your height and weight, and many pharmacies now ask for photo or video verification. A pharmacy can decline to supply if you do not meet the criteria. Any site offering these injections without a consultation should be avoided entirely.
Can you get weight loss injections on the NHS?
NHS access exists but is much narrower than private supply. Wegovy and Mounjaro are approved for NHS use in defined pathways, but prescribing is limited to specialist weight management services and, for Mounjaro (tirzepatide), a phased primary-care rollout that prioritises people with the highest BMI and multiple weight-related conditions. Ethnic BMI thresholds are usually reduced by 2.5 kg/m² for listed minority ethnic backgrounds under NICE/NHS guidance. If you think you may qualify, ask your GP before committing to private treatment — an NHS prescription costs at most the standard prescription charge in England and is free in Scotland, Wales, and Northern Ireland. See our NHS Mounjaro eligibility answer for cohort detail. This page is general information, not medical advice: speak to a pharmacist or GP about whether treatment is right for you.
People Also Ask
Why does the price go up during treatment?
These medicines are titrated — you start on a low dose and step up over several months to a maintenance dose. Higher-dose pens contain more medicine and cost the pharmacy more, so the monthly service price rises with each dose tier. Reputable pharmacies publish the price for every tier so you can see the full pathway before starting.
How much might year one cost privately?
As an illustration across providers, many people budgeting for titration plus months at maintenance should think in the low-to-mid thousands of pounds for weekly GLP-1 pathways — roughly £1,800–£3,600+ depending on medicine and dose path. Confirm live prices; this is not a quote.
Do I need a prescription for weight loss injections?
Yes. Wegovy, Mounjaro, and Saxenda are all prescription-only medicines. A registered prescriber must assess you first — online services do this through a questionnaire and identity or weight verification. Any website selling them without a consultation is operating illegally and the product may be counterfeit.
Are cheap weight loss injections online safe?
Prices far below the typical UK range are a warning sign for counterfeit or unregulated supply, which the MHRA has repeatedly warned about. Check the pharmacy is on the GPhC register, that a named prescriber reviews your consultation, and that the price covers genuine UK-supplied medicine with cold-chain delivery where needed.
What happens to the cost if I stop treatment?
You simply stop paying the monthly fee — there is no exit charge with reputable services, though check for subscription terms. Be aware that appetite commonly returns and weight regain is well documented after stopping, so factor the likely length of treatment into your budget rather than just the first month's price.
