Wegovy vs Mounjaro — which is cheaper in the UK?

Which is cheaper in the UK — Wegovy or Mounjaro?

On published private treatment-service prices, Wegovy is often cheaper at comparable points in titration, but not always, and the gap is smaller than social-media screenshots imply. Across GPhC-registered UK online pharmacies we track, Wegovy months typically sit around £100–£300 and Mounjaro around £130–£350. A 0.25mg Wegovy or 2.5mg Mounjaro starter month is the cheapest point on each pathway; 2.4mg Wegovy and 12.5–15mg Mounjaro maintenance months sit at the top.

These figures are editorial ranges from our treatment pages (checked against published pharmacy prices, last refreshed 10 July 2026). They are not a quote, not an average of every UK clinic, and not a recommendation to pick the cheaper pen. Manufacturer list prices and pharmacy bundling move the market — confirm live checkout prices.

Typical private prices by dose

Use this table to compare like-for-like titration stages, not brand names. Wegovy (semaglutide) and Mounjaro (tirzepatide) have different milligram strengths; 1mg of one is not 1mg of the other. The ranges below are the same dose-tier bands published on our Wegovy and Mounjaro comparison pages.

What does a private year actually cost?

Month one is a marketing number. An illustrative year-one private pathway — several cheaper titration months, then many months near maintenance — often lands roughly £1,800–£3,000+ for Wegovy and £2,000–£3,600+ for Mounjaro across the pharmacies we list. Someone who stays on a mid-tier dose, pauses, or is declined after consultation will spend less. Someone who titrates quickly to 2.4mg or 15mg will spend more.

If a clinic advertises “from £99” without saying which dose, assume it is the starter month. Ask for the price at the dose you would actually stay on, and whether consultation, needles, sharps disposal, cold-chain delivery, and dose reviews are included.

How should you compare two pharmacies fairly?

Look at the dose you expect to maintain, not only month one. Confirm whether consultation, needles, sharps disposal, and delivery are included. A low starter price with extras at checkout can cost more than a higher all-in figure. Check GPhC premises registration before you send ID or payment — a cheaper unregistered site is not a bargain.

Use the dose-tier tables on the Wegovy and Mounjaro treatment pages for live-style provider rows. This answer is a cross-medicine price map, not a substitute for those pages.

Who should skip a private price comparison?

Skip this page if you need a clinician to choose between semaglutide and tirzepatide — that is a medical decision about suitability, side effects, and supply, not a spreadsheet. Skip it if you may qualify for NHS specialist weight-management services: ask your GP first, because NHS treatment costs at most the standard prescription charge where you are eligible. Skip it if you are looking for a “best pharmacy” ranking we will not publish — we compare published service prices, we do not rank clinics by who pays us.

Does NHS access change the private price question?

Limited NHS pathways exist for both medicines, with stricter criteria than many private licences. For Mounjaro, primary-care access in England is phased by cohort — NICE-eligible does not mean automatic supply. Wegovy on the NHS is mainly via specialist weight-management services and varies by area. If you might qualify, speak to your GP before paying privately. Price alone should not decide the medicine.
