Cost of a Medical Weight Loss Program in the UK (October 2026)

01 · The price

What a medical weight loss programme costs with us

With EverydayMeds, the cost is one pen of Mounjaro after at least four weeks, priced by dose. The Mounjaro pen costs £169.99 at 2.5mg, £218.99 at 5mg, £279.99 at 7.5mg, £290.99 at 10mg, £319.99 at 12.5mg and £329.99 at 15mg. Each pen is a four-week supply. All six doses are in stock.

A new customer's first order is £40 off at any dose with code FIRST40. That includes people switching to us at a higher dose. Every later order gets an automatic £25 off (code DOSE25). Your first 2.5mg pen therefore costs £129.99 (standard price £169.99), and switching at 15mg means a first order of £289.99. You can see how the offers work on our Mounjaro discount code page.

02 · Included

What the price includes

The consultation is free, with no charge and no obligation. Payment is taken when you place the order; if the prescriber decides the treatment is not suitable, the order is refunded automatically in full. The price also covers:

• Free next-day tracked delivery in temperature-controlled, discreet packaging, with same-day dispatch when ordered by 3pm. Saturday delivery is £14.99.
• Needles, a sharps bin and injection guidance with every order.
• Ongoing monthly reviews, dose titration, follow-up assessments and side-effect support from the prescribing team.
• The free GLPTrackr companion app for tracking your treatment.

Each repeat order re-checks suitability. You can pay by Visa or Mastercard, or use Klarna and pay-monthly options.

03 · Planning

The year-one cost at a glance

These figures are standard prices before discounts.

A first order is £40 less and every later order £25 less than these standard prices. If you settle between those doses, use the monthly price for that dose: £279.99 at 7.5mg, £290.99 at 10mg or £319.99 at 12.5mg.

04 · How to start

How ordering works

Ordering takes three steps, starting with your free online consultation.

• Step 1: Complete the short health questionnaire. It is free and carries no obligation.
• Step 2: A GPhC-registered prescriber reviews it. Payment is taken when you place the order; if the prescriber decides the treatment is not suitable, the order is refunded automatically in full.
• Step 3: We dispense and dispatch, with free next-day tracked delivery.

Mounjaro is a prescription-only medicine, so approval depends on the prescriber's assessment. You can compare it with other options in our guide to all weight loss treatments.

05 · What counts as a programme

What counts as a medical weight loss programme

A medical weight loss programme is a clinician-supervised plan, usually built around a prescription medicine, rather than a diet club or a supplement. Costs vary because providers bundle different things. Some quote one headline figure that covers the consultation, the medicine and reviews. Others split these into separate fees, and the total only emerges at checkout.

When you compare programmes, split the cost into the same parts every time. The medicine is the largest part. Mounjaro is the brand name for tirzepatide, a once-weekly injectable prescription medicine made by Eli Lilly. In the UK it is licensed for weight management in adults and for type 2 diabetes. It comes as a pre-filled multi-dose KwikPen in six strengths: 2.5mg, 5mg, 7.5mg, 10mg, 12.5mg and 15mg.¹

Next come the clinical costs. These include the initial assessment, any blood tests a provider insists on, and follow-up reviews. At EverydayMeds the consultation is free, and monthly reviews, dose titration and side-effect support are part of the service. Delivery is the final part. Ours is free and next-day, with a £14.99 option for Saturday.

Some programmes also bundle coaching, meal plans or app access. These can be useful, but they are not the medicine. If a programme looks cheap, check whether the medicine is included at all, or whether you are paying for coaching and will have to buy the medicine separately.

Programmes built around medication still rely on lifestyle changes. Tirzepatide must be used alongside a reduced-calorie diet and increased physical activity, not instead of them.¹ A programme that promises results without any change to eating or activity is not describing how the medicine was studied.

Finally, look at how a provider handles price changes. Dose increases change the price of each pen, so a quote for the starter dose is not a quote for the whole programme. A transparent provider shows every dose price up front. We show all six on our product page. For a wider picture of what clinics charge, see our guide on how much medical weight loss costs and the page on the average cost at a medical weight loss clinic.

A practical way to compare is to write down three numbers for each provider: the cost of the first four weeks, the cost at your likely maintenance dose, and the total of any fees that are not the medicine. Providers that are hard to pin down on these three numbers are usually the ones that add costs later.

06 · Year-one cost planning

Planning the cost across a full year

Treatment begins at 2.5mg, then steps up depending on how you respond. If you step up after at least 4 weeks on each dose, the first four pens (2.5mg, 5mg, 7.5mg and 10mg) cost £959.96 at standard prices. A new customer's first order is £40 less, and every later order £25 less.

After titration, your prescriber and you agree a maintenance dose. This is not always the highest. The year total depends on where you settle. A first year costs £2,711.88 if you settle at 5mg, up to £3,599.88 at 15mg. Both figures cover 52 weeks, which is 13 pens, at standard prices before discounts.

For a maintenance dose between those two, the monthly price is the useful number. At 7.5mg a pen costs £279.99, at 10mg it costs £290.99, and at 12.5mg it costs £319.99. Multiply by the number of pens you need and subtract the relevant discounts.

Three things change the real figure. First, the discounts: your first order is £40 off with code FIRST40, and every later order is £25 off the standard price with code DOSE25. Second, the dose you settle at. Third, whether you stay on treatment for the whole year. Some people pause, and there is no subscription to cancel, because we do not auto-ship. Each repeat order is a fresh decision, rechecked for suitability.

Spreading the cost can help. Klarna and pay-monthly options are available, with no subscription lock-in. Using them does not change the price of the pens, only when you pay.

If you want to see how the programme looks as a plan rather than a price list, our Mounjaro weight loss program guide walks through the stages.

Lastly, treat a year total as a ceiling, not a forecast. Your prescriber may keep you on a lower dose, and your discounts apply to every later order.

07 · Comparing clinic quotes

How to compare quotes from named clinics

You may want to compare the cost of a specific clinic, such as Fit Medical Weight Loss, Medical Weight Loss by Healthogenics or Queen City Medical Weight Loss. The reliable route is to ask each clinic for a written, itemised quote and compare it on the same basis.

Use this checklist when you ask:

• What is the first-month total? Include the consultation, any tests, the medicine and delivery.
• Which medicine, and at which doses? A quote for a starter dose does not cover the full programme.
• Is the medicine included, or billed separately? Some programmes charge a membership and then add the medicine on top.
• What happens at each dose increase? Ask for every dose price in writing.
• What are the reviews and who carries them out? You want a regulated prescriber, not a form with a score.
• Can you stop without a fee? Subscriptions can be harder to leave than they are to join.

Reviews are worth reading, but read them for the pattern. Look for comments about billing surprises, how quickly questions were answered, and whether the clinical team followed up. Be wary of any review that promises a specific result, because results vary between people.

If a provider is in the UK and supplies prescription medicines, check it on the GPhC register. Our registration is 9012878, and you can check it on the register. Clinics outside the UK follow different rules, and their prices, medicines and consumer protections may not apply to you.

Across the UK pharmacies we track, Mounjaro pens range from £143.96 to £339.00 per month depending on dose and provider (checked 10 October 2026). The cheapest and dearest 2.5mg starter pens are £143.96 and £179.99. For the same dose, the gap between providers runs from £27 to £41. Boots' Mounjaro doses range from £179.00 to £339.00. These are tracked prices rather than a promise about what any provider will charge you, so confirm before you order.

08 · NHS versus private

NHS versus private: the honest picture

Mounjaro is available on the NHS, but access is being phased in over several years. NICE recommends it for adults with a BMI of at least 35 plus at least one weight-related condition. The NHS primary-care rollout began in June 2025 with the highest-need groups first, initially people with a BMI of 40 or more and four or more qualifying conditions.⁴⁶ Full rollout is expected to take years.⁵

Your GP or local NHS service can tell you where you sit in the rollout and whether you are eligible now. An NHS prescription is cheaper at the point of use, and if you pay prescription charges in England, the standard charge is £9.90 per item, though whether that applies depends on your circumstances and exemptions.

Private treatment is the alternative for people who meet the licensed criteria but are not yet reached by the NHS rollout. The licensed criteria are broader than NHS access. Mounjaro is licensed for weight management in adults with a BMI of 30 or above, or a BMI between 27 and 30 with at least one weight-related condition such as high blood pressure, high cholesterol, obstructive sleep apnoea, cardiovascular disease, prediabetes or type 2 diabetes.¹ It must be used alongside a reduced-calorie diet and increased physical activity.

A prescriber assesses your BMI, medical history and current medicines before deciding whether it is suitable for you. That applies in both settings. A private prescription is not an easier route to the medicine. It is a faster route for people who qualify, and it must still be clinically appropriate.

The practical comparison looks like this. The NHS route costs little at the point of use but may involve a wait, and you may not meet the current criteria. The private route costs the price of each pen, but you can start once a prescriber approves you. Some people use private treatment while waiting and move to NHS care later, if their eligibility changes. If you plan to do that, tell your GP about your treatment so your records stay accurate.

Whichever route you choose, avoid anyone offering to supply without a consultation or prescription. That is not treatment, and it carries real risks, including counterfeit pens.

09 · What results to expect

What results to expect for the money

Cost only makes sense next to what the treatment does, so here are the trial figures, with the caveat that your own result may differ. In the SURMOUNT-1 trial of 2,539 adults, people taking tirzepatide alongside diet and exercise lost on average 15% of their body weight on 5mg, 19.5% on 10mg and 20.9% on 15mg over 72 weeks, compared with 3.1% with lifestyle changes alone.²

These are trial averages, and individual results vary. Treatment works alongside a reduced-calorie diet and increased physical activity, not instead of them. At 72 weeks, 85% of participants on 5mg, 89% on 10mg and 91% on 15mg had lost at least 5% of their body weight. Half of participants on 10mg and 57% on 15mg lost at least 20% of their body weight.²

A worked example makes the percentages concrete. For someone starting at 100 kg, 20.9% is about 21 kg, and 15% is about 15 kg. Someone starting at a different weight would scale those figures accordingly.

Your prescriber reviews your progress and dose with you at monthly reviews.

This is also why the cost per month is not the whole calculation. A programme that costs less but does not suit you is poor value. One that includes monthly clinical reviews, dose adjustment and side-effect support gives you the chance to find the dose that suits you.

A useful question to ask any provider is not how much weight you will lose, because nobody can promise it. Ask what monitoring they provide, who adjusts the dose, and what happens if the medicine is not suiting you. Our guide to choosing a medical weight loss program covers those questions in more detail.

10 · Why the medicine costs what it does

How the medicine works

The medicine is the main cost, so it helps to know what you are buying. Tirzepatide is the first treatment of its kind to activate two natural gut-hormone receptors at once: GIP and GLP-1. Together these help regulate appetite, slow how quickly the stomach empties, and improve the way the body responds to insulin.¹

In practice, most people feel fuller sooner and less hungry between meals, which supports a reduced-calorie diet. This dual action is what distinguishes Mounjaro from single-action GLP-1 medicines such as semaglutide (Wegovy/Ozempic).¹

Tirzepatide has a half-life of about five days. After a final dose, it takes roughly 4 to 5 weeks to clear the system. There is no way to speed this up, and nothing needs doing while it clears.¹

We obtain Mounjaro directly from Eli Lilly's UK distribution through official LillyDirect supply. All six doses from 2.5mg to 15mg are stocked, and every pen is genuine KwikPen stock. For you, that means the price you see covers a medicine with a traceable supply chain.

Each KwikPen contains four weekly doses. That means a pen is a four-week supply, which is why prices are quoted per month.

11 · Safe ways to lower the cost

Ways to lower the cost, and shortcuts to avoid

The regulated way to reduce what you spend is the discounts.

A new customer gets £40 off a first order at any dose with code FIRST40, and every later order gets an automatic £25 off with code DOSE25. These apply to the standard prices shown on the page.

Finally, avoid anything priced far below the market. A very low price on a prescription medicine is more likely to signal a counterfeit than a bargain. Flexible payment is a safer way to ease the monthly cost: Klarna and pay-monthly options exist, with no subscription lock-in.

Programmes with no monthly fee deserve scrutiny too. With us there is no subscription fee, but you do pay for each pen you order. If a programme claims to have no cost at all, ask what you are getting and who is prescribing.

12 · Genuine pens and counterfeits

Buying safely: genuine pens and counterfeit risk

Price is a poor guide to safety, so check where the pen comes from. The MHRA has seized thousands of fake weight-loss pens in the UK and has issued alerts after falsified Mounjaro pens were identified. Fake pens have caused hospitalisations, and some contained insulin rather than tirzepatide.⁷

Only buy from a pharmacy you can verify on the GPhC register, never from social media, beauty salons or unverified websites.¹² Genuine treatment always involves a prescription and a clinical consultation. Anyone offering to supply without a consultation or prescription is a warning sign, however attractive the price.

Genuine UK stock is supplied through Lilly's official distribution to licensed pharmacies. Every pen carries a batch number and expiry date that can be checked.¹ A genuine UK Mounjaro pen comes from a registered pharmacy, arrives cold-chain packaged, and the solution inside is clear and colourless.

Do not use a pen that has been frozen, looks cloudy or discoloured, has particles in it, is past its expiry, has been above 30°C, or has been in use out of the fridge for more than 30 days.¹³ If supply or packaging ever seems wrong, check the pharmacy on the GPhC register and contact the pharmacy before injecting.

If you have a side effect or suspect a falsified pen, you can report it through the MHRA Yellow Card scheme.⁷

Our supply comes direct from Eli Lilly's UK distribution via LillyDirect, and our GPhC registration number is 9012878. Our delivery uses temperature-controlled, discreet packaging, free and next-day, with same-day dispatch when ordered by 3pm. Support is available Monday to Friday, 9am to 5pm, by email at support@everydaymeds.co.uk, through the account portal chat, or by phone on 0333 207 0413.

If you are weighing a very low quote from an unfamiliar seller, treat safety checks as the real cost of the purchase. A genuine pen from a verifiable pharmacy protects you, and that is worth more than a small saving.

13 · Serious side effects

Serious side effects: when to get help straight away

Serious side effects are uncommon but need urgent attention. Seek immediate medical help for: severe, persistent stomach pain that may spread to your back, with or without vomiting (possible pancreatitis); pain in the upper right abdomen, fever or yellowing of skin/eyes (possible gallbladder problems); or signs of a severe allergic reaction such as swelling of the face or throat and difficulty breathing. If you take insulin or a sulfonylurea alongside Mounjaro, watch for low blood sugar (shakiness, sweating, confusion) — your prescriber may need to adjust those medicines.¹
