Current Prices
Current Mounjaro Prices in the UK (2026)
Mounjaro is available through two routes in the UK: NHS specialist services and private pharmacies. The overwhelming majority of patients currently access it privately, as NHS provision remains restricted to defined referral pathways with strict eligibility criteria. Private prices are set independently by each pharmacy and vary across providers.
The prices below represent approximate 2026 UK market rates at each dose. These are indicative figures — always confirm current pricing directly with your chosen pharmacy before committing to treatment.

Pricing Factors
What Affects the Cost of Mounjaro in the UK?
Mounjaro pricing is not uniform across UK pharmacies. Several factors determine what patients pay, and understanding them helps in making informed decisions about where to access treatment.
Dose Level
The primary driver of Mounjaro pricing is the dose. Eli Lilly manufactures Mounjaro in six pen strengths — 2.5 mg, 5 mg, 7.5 mg, 10 mg, 12.5 mg and 15 mg — each containing four weekly doses (a one-month supply). Higher-dose pens contain more active tirzepatide per unit and are priced accordingly. Patients on the 15 mg maintenance dose pay significantly more per month than those starting on 2.5 mg, and the incremental cost increase across the six dose steps is more gradual than the four-step Wegovy schedule.
Subscription vs Pay-As-You-Go
Many UK pharmacies offer Mounjaro on a subscription basis at a modest discount compared with individual monthly purchases. For patients committed to long-term maintenance treatment, a subscription can reduce annual costs by £100 to £250 depending on the pharmacy and dose. Pay-as-you-go pricing offers greater flexibility but typically costs slightly more per month. Patients uncertain about long-term commitment may prefer to start pay-as-you-go before transitioning to a subscription once established on their maintenance dose.
Assessment and Consultation Fees
Some pharmacies charge a separate fee for the clinical assessment required before Mounjaro prescribing. Others — including Happy Pharmacy — provide a free online eligibility assessment as part of the service. When comparing prices between providers, it is important to account for all charges including assessment, medication and delivery, as these can vary meaningfully across the market.
Cold-Chain Delivery Costs
Mounjaro requires cold-chain storage and specialist packaging during delivery. Some pharmacies include these costs in the medication price; others charge separately. For patients ordering monthly, even a modest delivery charge accumulates significantly over a year. Confirming the all-in price before committing to a provider is strongly recommended.
Monthly Costs
Mounjaro Monthly Cost: What to Budget
Monthly Mounjaro costs align directly with the per-pen pricing at each dose step. Because Mounjaro's six-step escalation spans 20 weeks before reaching maintenance, the cost profile rises more gradually than the four-step Wegovy schedule — but over a longer period before stabilising.
Monthly Cost During Escalation (Months 1–5)
The first five months cover the full escalation from 2.5 mg to 15 mg. Costs begin at approximately £133 and increase by £20 to £55 at each dose step.
Subscription Savings
Subscription plans for Mounjaro at UK pharmacies typically offer savings of £10 to £30 per month compared with pay-as-you-go rates. For patients on long-term 15 mg maintenance, a subscription saving of even £20 per month represents a £240 annual reduction. Subscriptions also provide the practical benefit of automated monthly supply, reducing gaps in treatment caused by delayed reordering.
Budgeting for Treatment
Patients should plan for the full cost trajectory before starting treatment. Beginning at ~£133 per month may feel manageable, but the maintenance cost of ~£285 per month represents a substantially different ongoing commitment. A transparent discussion with your prescribing pharmacist about total cost expectations before the first injection is strongly encouraged.
| Month | Dose | Approx. Monthly Cost |
|---|---|---|
| Month 1 | 2.5 mg | ~£133 |
| Month 2 | 5 mg | ~£157 |
| Month 3 | 7.5 mg | ~£213 |
| Month 4 | 10 mg | ~£242 |
| Month 5 | 12.5 mg | ~£256 |
| Month 6+ | 15 mg | ~£285 (ongoing) |
Annual Costs
Mounjaro Annual Cost Estimate
The table below estimates total annual Mounjaro costs based on the standard escalation schedule, reflecting dose progression from month one through to a full year of 15 mg maintenance treatment.
On this basis, the estimated total cost of the first year of Mounjaro treatment — covering the full 20-week escalation and seven months of maintenance — is approximately £2,900 to £3,200 at standard pay-as-you-go rates, or modestly less with a subscription plan. Year two and beyond, assuming continued maintenance at 15 mg, would cost approximately £3,420 per year (£285 × 12).
| Period | Dose | Monthly Cost | Cumulative Cost |
|---|---|---|---|
| Month 1 | 2.5 mg | ~£133 | ~£133 |
| Month 2 | 5 mg | ~£157 | ~£290 |
| Month 3 | 7.5 mg | ~£213 | ~£503 |
| Month 4 | 10 mg | ~£242 | ~£745 |
| Month 5 | 12.5 mg | ~£256 | ~£1,001 |
| Months 6–12 | 15 mg | ~£285/month | ~£2,996 total |
Mounjaro vs Wegovy: Cost Comparison: Mounjaro's first-year treatment cost (~£2,900–£3,200) is higher than Wegovy (~£1,950–£2,200) — while producing higher average weight loss in head-to-head clinical trials. For many patients, this makes Wegovy a clinically and financially compelling starting point.

NHS Access
NHS Availability of Mounjaro
Mounjaro was recommended by NICE in 2024 (TA1026) for use within NHS specialist weight management services. As with Wegovy, NHS access remains restricted in 2026, and the majority of patients seeking Mounjaro do so through private pharmacies.
Who Can Get Mounjaro on the NHS?
NICE TA1026 specifies that Mounjaro is available on the NHS only through specialist tier 3 or tier 4 weight management services for adults meeting all of the following criteria:
- BMI of 40 or above (or 33 or above in certain high-risk ethnic groups)
- At least one weight-related comorbidity — type 2 diabetes, hypertension, sleep apnoea or other qualifying condition
- Active engagement with an NHS specialist weight management programme
- No contraindications to tirzepatide
| Route | Cost to Patient | Eligibility | Waiting Time |
|---|---|---|---|
| NHS England | £9.90 per prescription | Strict — NICE TA1026 specialist pathway only | Months to years |
| NHS Scotland | Not currently funded | N/A | N/A |
| Private pharmacy UK | ~£133–£285/month | Standard clinical criteria | Days to weeks |
Safety Warning
Why Cheapest Isn't Always Best for Mounjaro
The demand for weight loss injections has created a significant unregulated market. Social media platforms, unofficial websites and informal networks offer what they claim is Mounjaro at prices far below legitimate market rates. The risks of purchasing from these sources are serious.
The Counterfeit Risk
Mounjaro is a prescription-only medicine under the Human Medicines Regulations 2012. Selling it without a valid prescription is illegal. MHRA enforcement operations have identified multiple seizures of counterfeit tirzepatide and semaglutide products since 2023, including products containing incorrect concentrations, contaminated ingredients, or no active ingredient at all. Patients purchasing from unregulated sources have reported no weight loss effect, severe adverse reactions, and injection site infections from contaminated products.
Cold-Chain Integrity
Tirzepatide must be stored between 2°C and 8°C throughout the supply chain. Unregulated sellers have no obligation to maintain cold-chain standards. A Mounjaro pen that has been stored at ambient temperature may appear identical to a properly stored pen but contain significantly degraded active ingredient — producing no therapeutic effect and potentially posing safety risks.

Key Questions
Key Questions Answered
How much does Mounjaro cost in the UK?
In 2026, Mounjaro costs approximately £133 per month at the starting 2.5 mg dose, rising to around £285 per month at the 15 mg maintenance dose through a private UK pharmacy. The total first-year cost — covering the 20-week escalation and seven months of maintenance — is approximately £2,900 to £3,200 at standard pay-as-you-go rates. Subscription plans at some pharmacies offer modest discounts. NHS access is available for qualifying patients but remains restricted to specialist weight management services with significant waiting times.
Why does Mounjaro pricing vary?
Mounjaro prices vary between UK pharmacies for several reasons. The primary factor is dose — higher-dose pens contain more tirzepatide and cost more per month. Beyond dose, pricing reflects differences in pharmacy business models, whether consultation and delivery fees are bundled into the medication price, and whether subscription discounts apply. The MHRA-approved medication itself is identical regardless of provider — only the surrounding service, supply chain standards and price differ. Patients should compare total all-in costs rather than headline medication price alone.
Is Mounjaro available on the NHS?
Yes — Mounjaro was recommended by NICE in 2024 (TA1026) for use within NHS specialist weight management services. However, eligibility is strict: patients must have a BMI of 40 or above (or 33 or above in certain high-risk ethnic groups) with at least one weight-related comorbidity, and must be engaged with an NHS specialist weight management programme. Even qualifying patients face waiting times of months to years in most areas. NHS Scotland does not currently fund Mounjaro on its national medicines formulary. For the majority of patients, private prescribing through a GPhC-registered pharmacy remains the practical route to treatment in 2026.
