Wegovy Price UK 2026: Complete Cost Guide

Wegovy (semaglutide 2.4mg) is a GLP-1 receptor agonist manufactured by Novo Nordisk, approved for weight management in the UK. Like Mounjaro, it is available through private prescription and you pay the full cost yourself. As of March 2026, Wegovy prices in the UK range from approximately £150 to £300 per month, depending on the dose and pharmacy. Wegovy uses a different titration schedule to Mounjaro, with five dose levels:

• 0.25mg (weeks 1-4): £150 – £220
• 0.5mg (weeks 5-8): £155 – £230
• 1mg (weeks 9-12): £165 – £250
• 1.7mg (weeks 13-16): £175 – £270
• 2.4mg (week 17 onwards, maintenance): £190 – £300

Wegovy is injected once weekly, the same as Mounjaro. Each pre-filled FlexTouch pen contains four doses (one month's supply at the maintenance dose). Prices include the medication, but consultation and delivery fees may be charged separately depending on the pharmacy.

One of the most common questions from UK users is whether Wegovy or Mounjaro is cheaper. The answer depends on the dose, but in general, Mounjaro tends to be slightly cheaper at comparable points in the titration schedule, particularly at the cheapest pharmacies. Comparing monthly costs at the cheapest available pharmacies:

• Starter doses: Mounjaro 2.5mg (from ~£130) vs Wegovy 0.25mg (from ~£150) — Mounjaro cheaper by ~£20
• Mid-range doses: Mounjaro 10mg (from ~£160) vs Wegovy 1.7mg (from ~£175) — Mounjaro cheaper by ~£15
• Maximum/maintenance: Mounjaro 15mg (from ~£170) vs Wegovy 2.4mg (from ~£190) — Mounjaro cheaper by ~£20

Over a full 12-month treatment course, choosing Mounjaro over Wegovy could save approximately £200 to £400, depending on the doses used and pharmacies selected. However, medication choice should be based on clinical suitability first and cost second. Some patients respond better to semaglutide than tirzepatide, and vice versa.

Clinical trial data consistently shows Mounjaro producing greater average weight loss than Wegovy, though both are highly effective. In clinical trials:

• Mounjaro 15mg (SURMOUNT-1): 20.9% average body weight loss over 72 weeks
• Wegovy 2.4mg (STEP-1): 14.9% average body weight loss over 68 weeks

For a person weighing 100kg, that translates to roughly 21kg lost on Mounjaro versus 15kg on Wegovy. The difference is attributed to Mounjaro's dual mechanism: it targets both GLP-1 and GIP receptors, while Wegovy targets GLP-1 only. However, these are averages. Individual results vary significantly. Some people achieve better results on Wegovy than Mounjaro. Factors like genetics, diet, exercise, and adherence all influence outcomes. If one medication is not producing results after several months, your prescriber may recommend switching to the other. For a more detailed comparison, read our Mounjaro vs Wegovy guide.

Wegovy has been approved by NICE for NHS use in specialist weight management services since 2023. However, availability on the NHS is extremely limited. You must meet strict eligibility criteria:

• BMI of 35 or above (or 30+ with a weight-related health condition)
• Referred through a specialist weight management service
• Tried and failed with diet, exercise, and behavioural interventions

Even if eligible, NHS waiting lists for specialist weight management services are typically 12 to 24 months. Many areas of the UK have not yet started prescribing Wegovy on the NHS due to supply constraints and budget limitations. For most people wanting Wegovy or Mounjaro for weight loss, the private prescription route is the only realistic option in 2026. This means paying the full cost yourself through a private pharmacy or online prescriber.

Wegovy is available from many of the same online pharmacies that sell Mounjaro. Major providers include Boots, Superdrug, ZAVA, Numan, Pharmacy2U, and numerous smaller GPhC-registered online pharmacies. When choosing a Wegovy provider, the same advice applies as for Mounjaro:

• Verify the pharmacy is on the GPhC register
• Check the total price including consultation and delivery fees
• Ensure cold-chain delivery is included
• Read reviews and check the pharmacy's Trustpilot score
• Ask about subscription discounts if you plan to stay on treatment

The choice between Wegovy and Mounjaro depends on your individual circumstances, clinical history, and budget. Here is a summary to help you discuss the options with your prescriber:

• Choose Mounjaro if: You want the highest average weight loss, you prefer a lower monthly cost, or you have type 2 diabetes (Mounjaro is licensed for both diabetes and weight management).
• Choose Wegovy if: You have previously tried and responded well to semaglutide (Ozempic), you prefer a medication with a longer UK track record for weight management, or Mounjaro is unavailable at your preferred pharmacy.
• Either medication: Both are clinically proven, safe for most people, and far more effective than diet and exercise alone. The best medication is the one you can afford, tolerate, and adhere to consistently.

Ultimately, this is a clinical decision that should be made with your prescriber. Cost is a factor, but effectiveness, side effect tolerance, and your medical history should come first.
