Wegovy UK: Prices, Providers and Doses

Last updated: April 2026

Whether you are researching Wegovy in the UK — whether you are new to injectable weight-loss medication or comparing it against other options — this guide covers what you need to know. We explain how Wegovy works, who qualifies, what it costs across UK providers, and how it compares to Mounjaro. LetsLoseWeight is an independent comparison site; we are not affiliated with any pharmacy or medication manufacturer, and we do not sell or prescribe treatment.

What is Wegovy?

Wegovy is the brand name for semaglutide at doses specifically licensed for weight management. It is manufactured by Novo Nordisk and was granted MHRA approval for use in adults in the UK for weight management. Wegovy works by mimicking GLP-1, a naturally occurring hormone involved in regulating appetite and feelings of fullness. By activating GLP-1 receptors in the brain and gut, semaglutide reduces appetite, slows gastric emptying, and helps people eat less without the same intensity of hunger.

It is given as a once-weekly subcutaneous injection — typically into the abdomen, thigh, or upper arm — using a prefilled pen device. Like all prescription weight-loss medications in the UK, it must be prescribed by a registered clinician following an appropriate clinical assessment.

In clinical trials, participants taking Wegovy at the maintenance dose lost an average of approximately 15–17% of their body weight over 68 weeks. These are results from a specific trial population — individual results vary and are influenced by many factors, including adherence, lifestyle changes, and individual biology.

Who is eligible for Wegovy in the UK?

The licensed eligibility criteria for Wegovy are broadly the same as for other weight-management medications. Private prescribers will typically consider Wegovy for adults with a BMI of 30 kg/m² or above, or a BMI of 27 kg/m² or above in the presence of at least one weight-related health condition such as type 2 diabetes, high blood pressure, or raised cholesterol.

NHS eligibility is more restrictive and follows Tier 3 specialist service criteria (see below). Online providers conducting consultations privately are required to undertake a proper clinical assessment before issuing a prescription. Wegovy is contraindicated in pregnancy and in people with certain personal or family medical histories — including specific thyroid conditions. Your prescriber is the right person to assess whether Wegovy is appropriate for you specifically.

How much does Wegovy cost in the UK?

Wegovy's private cost in the UK varies by provider and dose. Approximate current monthly costs by dose stage are:

0.25mg (starter dose): approximately £129–£200 per month
0.5mg–1mg: approximately £150–£240 per month
1.7mg–2.4mg (standard maintenance doses): approximately £180–£300 per month
7.2mg (new higher dose, where available): pricing varies — check individual providers

These figures reflect the range across GPhC-registered UK providers as of April 2026 and are subject to change.

One notable pricing development: following Eli Lilly's UK price increase for Mounjaro in September 2025, Wegovy has become the more affordable of the two main injectable weight-loss medications on the UK private market. At comparable dose stages, Wegovy typically costs £50–£100 less per month than Mounjaro — over a full year, that difference can represent a saving of between £600 and £1,100.

Compare Wegovy providers

The UK private market for Wegovy includes a growing number of online providers operating under GPhC registration. These providers differ in how they price each dose, what their consultation process involves, how quickly they deliver, and what ongoing clinical support they provide.

LetsLoseWeight lists only GPhC-registered providers. Every provider on our platform has been independently verified as meeting UK regulatory requirements. Our ratings reflect verified patient feedback — providers cannot pay to improve their ranking or receive a favourable review. Our role is to give you the tools to compare, not to make the decision for you.

Wegovy doses explained

Wegovy follows a graduated dose-escalation schedule, beginning at a low starting dose to allow the body to adjust. The dose is then increased at intervals under prescriber supervision. The standard licensed dose steps are:

0.25mg → 0.5mg → 1mg → 1.7mg → 2.4mg

Each step is typically maintained for four weeks before progressing. The 2.4mg dose is the established maintenance dose used in clinical trials. Most patients remain on this dose long-term once they have worked up to it.

A new 7.2mg dose is now available in the UK for eligible patients. This higher dose is not the standard starting or maintenance dose — it is intended for a specific patient group and would only be prescribed where clinically appropriate. If you are curious about whether the 7.2mg dose applies to you, speak to your prescriber.

Dose increases should never be self-managed. Moving up the schedule too quickly — or skipping steps — significantly increases the risk of side effects, particularly gastrointestinal symptoms such as nausea and vomiting.

Wegovy vs Mounjaro — key differences

Wegovy and Mounjaro are the two leading injectable weight-loss medications currently available in the UK, and they are often compared directly. Here is how they differ in the most practically relevant ways.

Mechanism: Wegovy is a GLP-1 receptor agonist. Mounjaro is a dual GIP and GLP-1 receptor agonist — it activates an additional hormone pathway. Both reduce appetite and promote weight loss, but through partly different mechanisms.

Clinical trial outcomes: Clinical trials showed average weight loss of approximately 15–17% of body weight with semaglutide (Wegovy) and approximately 20–22% with tirzepatide (Mounjaro) at the highest doses. These are trial results, not guaranteed individual outcomes, and no direct head-to-head trial in a weight-management population has yet produced definitive comparative data.

Price: Following the Eli Lilly price increase in September 2025, Mounjaro became the more expensive option in the UK private market. At comparable dose stages, Wegovy is typically £50–£100 per month cheaper — a meaningful difference over the course of a treatment programme lasting a year or more.

Availability: Both medications are available privately from GPhC-registered UK providers. NHS access for both follows similar Tier 3 specialist criteria.

Whether Wegovy or Mounjaro is the right medication for you depends on your individual health profile, your prescriber's clinical assessment, and your personal priorities around cost and potential efficacy.

Is Wegovy available on the NHS?

Wegovy is available through the NHS, but access is limited to specialist services. In England, it is being introduced through NHS Tier 3 weight management services — it is not available through a standard GP consultation. Eligibility on the NHS typically requires a BMI of 35 kg/m² or above, or 30 kg/m² or above with a qualifying comorbidity such as type 2 diabetes or hypertension.

Referral to a Tier 3 service must come through a GP or other clinician. Waiting times for these services are currently lengthy in many parts of England — commonly 12–18 months — and availability depends on local NHS Integrated Care Board funding decisions, which vary by region.

Standard prescription charges apply in England (currently £9.90 per item), though many patients qualify for free prescriptions based on age, income, or medical exemption status. Prescriptions are free in Scotland, Wales, and Northern Ireland.

How to get Wegovy safely in the UK

As with all in-demand injectable weight-loss medications, counterfeit versions of Wegovy have been identified in the UK market. The MHRA has issued guidance warning patients about the risks of purchasing from unregulated sources — counterfeit products may be contaminated, incorrectly dosed, or stored outside the cold-chain requirements that maintain medication stability.

The only safe route to obtaining Wegovy is through a prescription from a GMC-registered prescriber, dispensed by a GPhC-registered pharmacy. Before using any online provider, take the following steps:

Search the GPhC register at pharmacyregulation.org to confirm the provider's pharmacy is registered
Verify that the clinician conducting your consultation is registered with the GMC or another appropriate UK regulatory body
Ensure you receive a genuine clinical consultation — not simply an automated form
Check that medication arrives in original, sealed manufacturer packaging with a visible batch number and expiry date

Every provider listed on LetsLoseWeight has been verified as GPhC-registered. If you see a provider offering Wegovy without prescription, or at prices substantially below the current market range, treat this as a serious warning sign and do not purchase.

Frequently Asked Questions

How much does Wegovy cost per month in the UK?

Private Wegovy costs currently range from approximately £129–£200 per month at the starter dose, rising to approximately £300 at the standard 2.4mg maintenance dose. Prices vary across GPhC-registered providers, so comparing before committing is worthwhile. Pricing for the new 7.2mg dose varies — check individual providers for current figures.

Is Wegovy cheaper than Mounjaro in 2026?

Yes, in most cases. Following Eli Lilly's UK price increase for Mounjaro in September 2025, Wegovy is now typically £50–£100 per month cheaper than Mounjaro at comparable dose stages. Over a full year of treatment, this can represent a saving of £600–£1,100. Both medications are available from GPhC-registered UK providers.

What is the difference between Wegovy and Ozempic?

Both Wegovy and Ozempic contain semaglutide — the same active ingredient. The key difference is that Ozempic is licensed for the management of type 2 diabetes, while Wegovy is licensed specifically for weight management at higher doses. They are not interchangeable, and Ozempic should not be used off-label for weight loss. If you are looking for a medication specifically for weight management, Wegovy is the licensed option.

How long does Wegovy take to work?

Appetite changes are often noticed within the first few weeks of treatment. Noticeable weight loss typically begins within the first one to three months. Clinical trials ran over 68 weeks, and results continued to develop over that period. Sustained results are associated with continued use alongside dietary and lifestyle changes.

Can I get Wegovy on the NHS?

Yes, but access is restricted. NHS Wegovy is available through Tier 3 specialist weight management services for patients meeting specific criteria — typically a BMI of 35 or above, or 30 or above with a qualifying comorbidity. Waiting times in many areas are currently 12–18 months. It is not available through a standard GP appointment.

What are the side effects of Wegovy?

The most commonly reported side effects are gastrointestinal: nausea, vomiting, diarrhoea, constipation, and stomach discomfort. These tend to be most noticeable when starting treatment or increasing the dose, and often improve over time. Rarer but more serious potential effects include pancreatitis and gallbladder-related problems. Your prescriber should discuss all relevant risks with you before starting treatment.

What is the starting dose of Wegovy?

The starting dose of Wegovy is 0.25mg, taken once weekly for four weeks. This is a dose-adjustment phase designed to minimise early side effects — the 0.25mg dose is not considered the therapeutic maintenance dose. Dose escalation from there is managed by your prescriber based on your response and tolerance.
