How to choose the right provider

Selecting a weight loss clinic is a significant decision that affects both your health and finances. Consider the following factors:

Clinical support level

Some providers offer a basic prescribing service with minimal ongoing contact, while others embed the medication within a comprehensive support programme. Evidence consistently shows that combining GLP-1 medication with structured behavioural support produces better outcomes. If you are new to weight management treatment, a provider offering dietitian support, health coaching and regular clinical review is likely to be more effective than a prescription-only service.

Medication choice

Not all providers offer all medications. If you have a specific preference — for example, Mounjaro based on the stronger weight loss data, or Wegovy based on the cardiovascular outcomes evidence from the SELECT trial — check that your preferred provider stocks it. See our Ozempic vs Wegovy comparison and full three-way comparison for guidance on choosing a medication.

Pricing transparency

Look beyond the headline monthly price. Some providers charge separately for consultations, blood tests, delivery or dose changes. Others bundle everything into a single monthly fee. Calculate the true total cost over the first 4 to 6 months, including any dose-escalation costs, before committing.

Regulation and safety

This is non-negotiable. Ensure that:

• The prescribing clinician is registered with the GMC (check at gmc-uk.org)
• The dispensing pharmacy is registered with the GPhC (check at pharmacyregulation.org)
• If the clinic provides face-to-face services in England, it should be CQC-registered (check at cqc.org.uk)

NHS vs private: which route is right for you?

The choice between NHS and private treatment depends on your individual circumstances:

• Choose NHS if: You meet the NICE eligibility criteria, are willing to wait for a Tier 3 appointment and prefer the reassurance of specialist multidisciplinary oversight at no additional cost beyond the prescription charge. See our guide to getting Wegovy on the NHS.
• Choose private if: You do not meet NHS criteria, cannot wait for the Tier 3 referral, or prefer the convenience and speed of private prescribing.

Frequently asked questions

Do I need a GP referral to use a private clinic?

No. Private weight loss clinics in the UK can prescribe directly following their own clinical assessment. You do not need a referral from your GP. However, it is advisable to inform your GP that you are taking a GLP-1 medication so that it can be recorded in your medical notes and considered alongside any other treatments.

Are online weight loss clinics safe?

Regulated online clinics with GMC-registered prescribers and GPhC-registered pharmacies are generally safe. The key is to verify the regulatory status of any provider before using their services. Avoid any provider that does not require a clinical assessment before prescribing.

Can I switch between private providers?

Yes, you can switch between private providers at any time. However, the new provider will typically want to conduct their own clinical assessment before continuing your prescription. If you are mid-way through a dose escalation, ensure the new provider is aware of your current dose and treatment history.

What if I experience side effects?

Any reputable provider should have a clear pathway for managing side effects, including access to a clinician for advice. If you experience serious side effects, contact your GP, call NHS 111 or attend A&E as appropriate. For guidance on common side effects, see our GLP-1 side effects guide and Ozempic side effects guide.
