How much do weight-loss injections cost in the UK in 2026?
Private weight-loss injections in the UK typically run from around £100 to £350 a month depending on the medicine and dose — but the headline 'from' price rarely tells the whole story.
The headline numbers
In 2026, private weight-loss injections in the UK usually cost between about £100 and £350 a month, depending on the medicine and your dose. Mounjaro (tirzepatide) commonly starts around £149–£230 a month; Wegovy (semaglutide) around £89–£200; Saxenda (liraglutide) and generic liraglutide around £75–£250. Prices rise as your dose increases during titration, so the starting price is usually the lowest you'll pay.
The extras that are easy to miss
The medicine is only part of the bill. Check whether the price includes the consultation, the injection pens and needles, delivery, and any blood tests or ongoing monitoring — some providers bundle these in, others charge separately. A headline 'from £149' with a £49 consultation, paid needles and delivery on top can quietly become £200+. Comparing the true monthly cost, not just the headline, is the single most useful thing you can do.
Where the price differences come from
Cost varies with (a) the medicine and dose, (b) whether you're paying for a bundled programme with coaching and app support versus a pharmacy-only supply, (c) branded versus generic products — as patents expire, cheaper generics such as generic liraglutide are appearing alongside branded Saxenda, and (d) introductory offers, which can make the first month much cheaper than the ongoing price.
How to keep the bill down
Three reliable savings: (1) compare the total monthly cost including consultation, needles and delivery — not the headline 'from' price; (2) ask whether a generic version is available for your medicine; and (3) because prices move and providers run offers, it's worth re-checking periodically and switching if a like-for-like supply is cheaper elsewhere. A prescriber must still confirm any medicine is right for you.

Frequently asked
- Why is the same medicine cheaper at one provider than another?
- Mostly because of what's bundled and how they price. A low headline figure may exclude the consultation, needles or delivery, or be a first-month offer; a higher figure may include coaching, monitoring and support. Compare the total monthly cost for the same medicine and dose, including any extras.
- Are generic weight-loss injections cheaper than branded ones?
- Often, yes. As patents expire, generic versions (for example generic liraglutide) are entering the UK market alongside branded products like Saxenda, usually at a lower price. Branded and generic versions of the same molecule can sit side by side at different prices — many people still choose the branded product, and both require a prescription.
- Does health insurance cover weight-loss injections?
- Rarely for private self-pay weight management, and cover varies by policy. Most people accessing weight-loss injections privately pay out of pocket. Always check your specific policy before assuming it's covered.
