Mounjaro on the NHS: Eligibility and Access Explained

Is Mounjaro available on the NHS?

Yes. Mounjaro is the brand name for tirzepatide, a once-weekly prescription injection. NICE recommends tirzepatide as an option for managing overweight and obesity in certain adults when it is used alongside a reduced-calorie diet and increased physical activity.

That recommendation does not mean every person who meets the NICE criteria can immediately receive Mounjaro from a GP. NHS England is introducing access in stages while local services develop prescribing pathways, staff training and the required dietary and physical-activity support.

This page focuses on access in England because NHS commissioning differs across the UK. If you live in Scotland, Wales or Northern Ireland, ask your local NHS service which pathway applies. Our broader guide explains the current position for NHS weight loss injection criteria across the UK.

Who can get Mounjaro through NHS primary care in England?

As of October 2026, NHS England says that primary-care access is prioritised for adults with a BMI of 35 kg/m² or more who have four of the following five weight-related health conditions:

• hypertension, which means high blood pressure
• dyslipidaemia, which means abnormal blood-fat levels
• obstructive sleep apnoea
• cardiovascular disease
• type 2 diabetes

The BMI threshold is reduced by 2.5 kg/m² for people from South Asian, Chinese, other Asian, Middle Eastern, Black African or African-Caribbean family backgrounds because health risks can occur at a lower BMI.

These are criteria for clinical assessment, not an automatic entitlement to treatment. A prescriber still needs to review your health, current medicines, contraindications, preferences and ability to engage with the required support programme.

Are the criteria different in specialist weight-management services?

They can be. NICE TA1026 recommends tirzepatide for adults with a BMI of 35 kg/m² or more and at least one weight-related health condition. It may also be considered for adults with a BMI from 30 to 34.9 kg/m², at least one weight-related condition and eligibility for referral to specialist weight-management services.

The same 2.5 kg/m² BMI adjustment applies for the ethnic backgrounds listed above. In practice, access still depends on referral pathways, local service capacity and a clinician deciding that treatment is appropriate.

Why does Mounjaro NHS access vary by area?

NHS England is using a phased rollout because treatment requires more than supplying an injection. People prescribed tirzepatide for obesity should receive wraparound care, including support with nutrition and physical activity, plus appropriate monitoring and review.

Integrated care boards need to commission services, agree local pathways and ensure clinicians have the resources to deliver this care safely. One area may therefore accept primary-care referrals while another relies mainly on specialist services. There is no single national waiting list that guarantees the same access date everywhere.

If you have seen claims about bypassing or beating an NHS queue, treat them cautiously. A regulated private pharmacy offers a separate clinical route rather than priority within the NHS. Our article on weight loss injections on the NHS explains that distinction in more detail.

How to ask for a Mounjaro NHS assessment

1. Contact your GP practice. Ask whether the local integrated care board currently funds tirzepatide assessments through primary care or a specialist service.
2. Prepare your health information. A clinician may need an up-to-date BMI, details of relevant diagnoses and a complete list of medicines.
3. Ask about referral options. If primary-care prescribing is not available, ask whether a specialist weight-management referral may be appropriate.
4. Discuss alternatives. If Mounjaro is unsuitable or unavailable, a clinician can explain other weight-management support and treatments.

You can check your BMI against the usual treatment thresholds with our BMI calculator for weight-loss injection eligibility. The Mounjaro weight loss calculator provides a general calorie and weight-loss estimate. A healthcare professional should confirm your measurements and assess the wider clinical picture.

What if you cannot access Mounjaro on the NHS?

Some people consider private treatment when they are not eligible for the current NHS phase or cannot access a local service. NHS ineligibility does not prove that private treatment is suitable, and private eligibility does not mean the NHS made the wrong decision. The two routes use different commissioning rules.

If you explore private care, use a registered pharmacy that provides a proper consultation, identity checks, clinical follow-up and a clear way to contact the prescribing team. Avoid medicines offered through social media, messaging apps or sellers that provide treatment without an assessment. Our guide explains how to choose a GPhC-registered Mounjaro pharmacy.
