Weight Loss Treatment Price Comparison UK 2026: Mounjaro and Wegovy

Private weight loss treatment typically costs between £130 and £350+ per month in the UK. The amount you pay depends mainly on which medicine you are prescribed, your current dose, the provider you use, consultation charges, delivery costs, subscription or programme fees, and what ongoing clinical support is included.

This makes straightforward price comparison more difficult than it first appears. A pharmacy may advertise a competitive starter price, for example, but that does not necessarily tell you how much you could pay once your dose increases. For that reason, one of the most useful ways to compare providers is to check the same medication at the same dose.

If you are comparing Mounjaro 5 mg, for example, compare 5 mg prices between providers rather than comparing a Mounjaro starter offer with the cost of a higher-dose treatment elsewhere. Our live comparison matrix tracks provider pricing by dose to make this type of like-for-like comparison easier — see the live UK weight loss treatment price comparison.

This guide focuses on two prescription injectable weight-management treatments commonly compared through UK private providers. The treatment and dose appropriate for an individual should be determined through a clinical assessment rather than by price alone.

1. Mounjaro contains tirzepatide and is administered once weekly. It acts on both GIP and GLP-1 receptors and is available in several dose strengths ranging from 2.5 mg to 15 mg.
2. Wegovy contains semaglutide and is also administered once weekly. Treatment normally begins at a low dose before gradually increasing according to the prescribed dosing schedule.

Both are prescription-only medicines. If you want to compare the medicines themselves rather than simply their cost, see our independent Mounjaro vs Wegovy comparison.

Prices vary considerably between providers and can change frequently. The figures below should be treated as indicative market ranges, not guaranteed prices. For provider-by-provider prices checked against our latest dataset, use the live comparison instead.

Mounjaro Price by Dose

Mounjaro is available in six dose strengths: 2.5 mg, 5 mg, 7.5 mg, 10 mg, 12.5 mg, and 15 mg. The cost usually increases as the dose rises. When comparing Mounjaro prices, check your actual dose alongside the standard price, introductory discount, repeat-order price, delivery, consultation charges and subscription requirements.

Indicative prices based on Healthwise360 monitoring of UK providers. Provider prices, discounts and availability can change — check the live Mounjaro price comparison before purchasing.

The difference between the lowest and highest provider price becomes particularly noticeable at higher doses. That means someone comparing only introductory 2.5 mg prices may get a very different picture from someone comparing the expected cost later in treatment.

Wegovy Price by Dose

Wegovy follows a gradual dose-escalation schedule. Treatment normally starts at 0.25 mg once weekly before increasing through 0.5 mg, 1 mg, 1.7 mg and the standard 2.4 mg weekly dose where clinically appropriate.

Patients should not increase their dose independently — the appropriate dose and escalation schedule must be determined by the prescribing healthcare professional. For more detailed information about Wegovy, see our Wegovy weight loss guide, or compare provider pricing on our Wegovy prices UK page.

For a simple overview, the current private-market picture looks approximately like this:

These ranges are useful for budgeting, but they should not be used to decide which medicine is clinically appropriate. The price you personally pay will depend on your prescription, dose and provider.

One of the most important things to understand when comparing weight loss treatment prices is that the advertised medication price may not be the final amount you pay. Several additional costs can change the total:

• Consultation fees: some providers include the clinical consultation within the advertised treatment price, others charge separately. Check whether initial and repeat consultations are included before comparing one provider with another.
• Delivery charges: delivery may be included or charged separately. A provider with a slightly cheaper medicine price can become more expensive once delivery is added.
• Dose increases: for medicines using dose escalation, your monthly spend may rise as your prescribed dose increases — one of the biggest reasons not to compare providers using starter prices alone.
• Subscription pricing: some providers offer one-off purchases, while others use recurring subscriptions or treatment programmes. Check whether the advertised price depends on signing up to a subscription.
• Introductory discounts: a discounted first order can make one provider appear considerably cheaper. Check what you will pay on your second and subsequent orders.
• Monitoring or programme fees: some services include additional clinical monitoring, coaching or weight-management support, which may be included within the medicine price or charged separately.

For a fair comparison, calculate the total expected monthly cost, rather than comparing one number from an advert. See our current UK provider prices for a full breakdown.

Check the quantity and supply period covered by each advertised price. A price per pen, a charge every four weeks and a charge per calendar month are different units and should not be treated as equivalent.

Before comparing providers, check the medicine, prescribed strength, quantity supplied, billing interval and any separate consultation, delivery or programme fees.

If the provider does not clearly explain what the quoted price covers, ask it to confirm before paying.

A useful price comparison involves more than sorting providers from cheapest to most expensive. Here are five checks worth making.

1. Check the Supplying Pharmacy

Confirm which pharmacy will actually dispense the medicine. You can independently check pharmacy registration using the General Pharmaceutical Council register. Healthwise360 records pharmacy and regulatory information within its comparison data to make provider checking easier — see our guide to verifying pharmacies.

2. Compare the Same Medication and Dose

Make sure you are comparing like with like. Mounjaro 10 mg vs Mounjaro 10 mg is a meaningful provider price comparison; comparing a discounted 2.5 mg starter pen with a different provider's 10 mg price is not. Dose-level comparison becomes increasingly important as treatment progresses.

3. Look Beyond the Headline Price

Before deciding which provider appears cheaper, check consultation charges, delivery, subscriptions, repeat-order prices, introductory promotions, and additional programme fees. A £5 saving on the advertised treatment price can disappear quickly if another provider includes delivery or consultations.

4. Consider the Service as Well as Price

Price matters, but it should not be the only factor. Also check how the clinical assessment works, who supplies the prescription, the dispensing pharmacy, access to clinical support, delivery arrangements, independent customer reviews, and how clearly the provider explains its fees. For prescription treatment, the cheapest price is not automatically the best-value service.

5. Use Current Data

Weight loss treatment prices can change frequently. A comparison article published several months ago can become outdated even if the treatment information remains accurate. Healthwise360 maintains a live provider matrix separately from this guide, covering more than 60 UK weight-management providers at the time this page was last updated, so you can check current prices by treatment and dose.

The annual cost can be significantly higher than the number suggested by an introductory monthly offer. As a rough illustration, based on higher and maintenance-range doses:

These figures are estimates rather than quotes. Your actual first-year cost may also differ because treatment commonly involves a period of dose escalation rather than spending an entire year at one dose. Provider prices can also change during treatment. For this reason, it is sensible to consider potential longer-term affordability, not simply whether the first month fits your budget.

There is no single treatment that is always cheapest for every person or every stage of treatment. At starter doses, Mounjaro and Wegovy can sometimes appear relatively close in price. At higher doses, the gap between providers can become much larger.

More importantly, medication should not be selected primarily according to price — the appropriate treatment depends on clinical factors that need to be assessed by a qualified prescriber. A more useful question is: “What does the treatment I have been prescribed cost across reputable UK providers at my current dose?” That is the comparison our cheapest weight loss treatment UK cost comparison guide is designed to answer.

Sometimes — but not consistently. At lower dose levels, prices for Mounjaro and Wegovy can overlap considerably. As doses rise, Mounjaro can become more expensive at some providers, particularly at its higher strengths.

However, provider pricing changes regularly, so a fixed statement that one medicine is always cheaper than the other would be misleading. If you have already been prescribed a treatment, compare the exact dose across several providers rather than relying on general averages.

Some prescription weight-management medicines are available through NHS pathways for eligible patients, but access is subject to clinical criteria and local service arrangements. In England, access to Mounjaro for weight management is being introduced through a phased NHS rollout, including specialist weight-management services and prioritised groups in primary care.

Eligibility is therefore different from simply being medically licensed to use the medicine privately. Wegovy may also be prescribed through eligible NHS weight-management pathways. If you want to explore NHS treatment, speak to your GP or relevant NHS weight-management service rather than assuming that private eligibility automatically means NHS eligibility.

Healthwise360 is an independent comparison platform. We do not prescribe weight loss medication — our purpose is to make provider information easier to compare before someone begins a consultation. Our comparison process considers:

• Pharmacy registration: we check supplying pharmacy information against the General Pharmaceutical Council register.
• Dose-specific pricing: where possible, we record prices at individual dose levels rather than publishing only an introductory “from” price.
• Additional costs: we look for charges such as delivery or other fees that may affect the total amount paid.
• Provider information: we record provider and dispensing-pharmacy information to help users understand who is supplying the service.
• Data updates: weight loss treatment prices change frequently, so our live comparison data is reviewed and updated separately from longer-form guides such as this article.

Not necessarily. Price is useful when you are comparing equivalent services, but it should be considered alongside pharmacy regulation, prescribing process, clinical support, delivery, transparency, provider reputation, and the total cost rather than the introductory price.

For prescription medicines, a provider being £5 or £10 cheaper should not outweigh concerns about the quality or legitimacy of the service. The aim should be to make a safe, informed and financially realistic comparison.

Weight loss treatment prices in the UK can vary considerably between medicines, dose levels and providers. As a broad guide:

• Mounjaro: approximately £130 to £340+ depending on dose
• Wegovy: approximately £130 to £295+ across the commonly compared standard dose range

But those numbers only tell part of the story. Consultation fees, delivery charges, subscriptions, introductory discounts and dose increases can all change the actual amount you pay. The most useful approach is to compare the same treatment at the same dose, check the total cost, and verify the provider and supplying pharmacy.

Healthwise360 tracks current advertised prices across more than 60 UK weight-management providers to make that comparison easier.

Before starting or changing any prescription weight-management treatment, speak to an appropriately qualified healthcare professional.
