If you're accessing Mounjaro privately in the UK (as most people currently are), the monthly cost depends on your dose, your provider, and whether additional fees apply. Here's a breakdown as of April 2026.
Monthly cost by dose
Prices vary between providers, but typical ranges for a 4-week supply (one pre-filled pen with 4 doses) are:
| Dose | Typical Monthly Cost | Notes |
|---|---|---|
| 2.5mg (starting) | £189–£210 | First 4 weeks only |
| 5mg | £189–£220 | First therapeutic dose |
| 7.5mg | £195–£225 | Mid-range escalation |
| 10mg | £200–£230 | Higher doses often cost more |
| 12.5mg | £205–£235 | Approaching maintenance |
| 15mg (maintenance) | £210–£250 | Maximum dose — long-term cost |
The September 2025 price increase
Eli Lilly increased the wholesale price of Mounjaro in the UK in September 2025, which was passed on to patients by most providers. Before the increase, starting doses were often available from around £149–£179/month. The increase pushed prices up by roughly £20–£50 per month depending on the dose and provider, prompting some patients to consider switching to Wegovy as an alternative.1
Additional costs to watch for
- Initial consultation fee: Some providers charge £50–£150 for the first clinical assessment. Many online services include this in the first month's price, while traditional private clinics often charge it separately
- Follow-up consultations: Some providers include monthly check-ins; others charge extra (£30–£75 per follow-up)
- Delivery: Usually included, but some providers charge £5–£10 for tracked delivery
- Needles: Pre-filled pens include needles, so this shouldn't be an extra cost
- Blood tests: Some providers require baseline blood tests (HbA1c, renal function, thyroid). If not included, expect £50–£200 depending on the panel
Always check the total cost including all fees before committing to a provider. A headline price of £189/month that doesn't include a £100 consultation fee is actually £289 in month one.
NHS cost
If you qualify for Mounjaro on the NHS (see our NHS eligibility guide), the cost is simply the standard NHS prescription charge: £9.90 per item in England. Prescriptions are free in Scotland, Wales, and Northern Ireland. However, the vast majority of people don't currently meet the strict NHS criteria.
Annual cost
At private prices, a year of Mounjaro treatment costs approximately £2,300–£3,000 depending on your dose and provider. This is a significant ongoing expense, particularly given that weight regain is common after stopping treatment, meaning many people may need to continue indefinitely.
How to find the best price
Prices vary meaningfully between UK providers — sometimes by £30–£50/month for the same dose. For an editorial comparison of providers, see our UK providers guide. Always verify that any provider is GPhC-registered and uses a qualified prescriber.
