Private GLP-1 prescriptions: what to know before you buy

Many people who want GLP-1 treatment in the UK choose to go through the private route rather than access through the NHS. This guide covers how to do it safely, what a legitimate provider looks like, and what costs you can expect.

NHS access to weight loss medicines is still limited and being introduced in stages. Mounjaro is being rolled out through GP surgeries, with initial eligibility focused on people with a BMI of 40 or above plus at least four qualifying weight-related conditions.

NHS England estimates that around 3.4 million people could eventually be eligible, but projects that around 220,000 will gain access during the first three years.

For people who do not meet NHS criteria, or whose local service has not started prescribing, private treatment may be the available route. This reflects how NHS access is currently structured, rather than anything about an individual's circumstances.

Private eligibility can be wider than NHS criteria. Depending on the medicine and clinical assessment, regulated providers may prescribe weight loss medication to adults with a BMI of 30 or above, or 27 or above with a weight-related condition such as high blood pressure or prediabetes.

For this reason, many people who want prescription weight loss medication currently explore private treatment rather than waiting for NHS access.

A regulated provider is one that's registered with the General Pharmaceutical Council (GPhC) for pharmacies, or the General Medical Council (GMC) for the doctor who prescribes. Clinics offering consultations are usually also registered with the Care Quality Commission (CQC).

Unregulated sellers sit outside this system entirely. They might operate through social media, beauty salons, or websites with no real clinical oversight.

Here's what separates the two.

The MHRA (Medicines and Healthcare products Regulatory Agency) is the body that decides whether a medicine is safe and effective enough to be sold in the UK.

Licensing applies to the medicine itself, not to whoever happens to be selling it. A genuine Mounjaro pen bought from an unregulated seller is still a risk, because you can't be sure it's genuine at all. Counterfeit products sold under the same branding have turned up mixed with insulin, or containing no active ingredient whatsoever. 

The MHRA treats this as an ongoing enforcement priority, and counterfeit packaging can be difficult to tell apart from the real thing.

Before buying from any online pharmacy, you can check it's genuinely registered on the GPhC online register. All pharmacies listed with us at Find Care Compare are GPhC registered.

A proper consultation, whether online or in person, should feel thorough. You should expect it to cover:

If a provider is willing to prescribe without asking about any of this, that's a sign the consultation is a formality rather than a genuine clinical check.

Private GLP-1 treatment is a long-term cost. Most people stay on treatment for 12 months or longer, and the price usually rises as your dose increases. 

Some costs are added on separately to the medication itself, including:
