How to Get Mounjaro in the UK: NHS vs Private

Mounjaro (tirzepatide) is licensed in the UK for weight management and type 2 diabetes. But getting hold of it isn't always straightforward — the NHS route has strict criteria and long waits, while the private route requires navigating dozens of online providers.

This guide walks you through both options.

Route 1: NHS

Eligibility

Following NICE approval, Mounjaro is available through NHS specialist weight management services for adults who meet all of the following:

• BMI of 35 or above (or 30+ with weight-related comorbidities)
• Have tried diet and exercise programmes without sufficient results
• Are referred to a specialist weight management service by their GP

What to expect

1. See your GP — ask for a referral to the local weight management service
2. Wait for assessment — typical waiting times are 6–18 months depending on your area
3. Specialist assessment — the team decides on the most appropriate treatment
4. Start treatment — if Mounjaro is prescribed, it's dispensed through the NHS at standard prescription cost (£9.90 per item in England, free in Scotland/Wales)

Pros and cons

Pros: Free (or standard prescription charge), medically supervised, specialist team support

Cons: Long waiting lists, strict eligibility criteria, may be prescribed an alternative medication, limited to areas with funded services

Route 2: Private

How it works

Private providers offer Mounjaro through an online consultation process:

1. Choose a provider — compare prices and what's included
2. Complete a health assessment — online questionnaire about your medical history, current medications, BMI, and weight loss goals
3. Prescriber review — a GMC-registered doctor or qualified prescriber reviews your assessment
4. Prescription and dispatch — if clinically appropriate, the medication is prescribed and posted to you (usually next-day delivery)
5. Ongoing support — dose escalation reviews, typically every 4 weeks

Eligibility

Private providers generally follow the same clinical guidelines:

• BMI of 30+ (obese), or
• BMI of 27+ with a weight-related condition

Some providers may have slightly different criteria. All legitimate providers will decline to prescribe if it's not clinically appropriate — be wary of any provider that guarantees a prescription before assessment.

What to look for in a provider

Essential (non-negotiable):

• GPhC-registered pharmacy or CQC-regulated service
• GMC-registered prescriber
• Clinical assessment before prescribing
• UK-sourced, genuine medication

Good to have:

• Ongoing monitoring included in price
• Prescriber access between appointments
• Clear dose escalation protocol
• Transparent pricing (no hidden fees)

Cost

Private Mounjaro typically costs £35–75 per week depending on the dose and provider. Most providers include the consultation in this price.

Red flags to watch for

Avoid any provider that:

• Is not GPhC or CQC registered — this is illegal
• Doesn't require a health assessment — a prescription without assessment is unsafe
• Offers prices that seem too good to be true — counterfeit tirzepatide exists
• Ships from outside the UK — importation of prescription medicines is illegal for individuals
• Guarantees a prescription — legitimate providers must be able to decline

NHS or private: which is right for you?

Choose NHS if:

• You meet the strict eligibility criteria
• You can wait 6–18 months to start
• Cost is the primary factor
• You want a specialist multidisciplinary team

Choose private if:

• You want to start treatment within days
• You don't meet NHS criteria (e.g., BMI 27–34)
• You want flexibility in dose and brand choice
• You can budget £35–75/week

Most patients who start privately can transition to NHS provision later if they meet the criteria and a service becomes available in their area.
