Tips for Managing Costs

Check NHS eligibility first

If you meet NICE criteria, Wegovy is available free through NHS specialist weight management services. Waiting lists vary, but it's worth asking your GP about a referral alongside exploring private options.

Compare during escalation, not just maintenance

You'll be on lower (cheaper) doses for 4-5 months during escalation. Some clinics are significantly cheaper at starter doses. Use the calculator above to compare at each dose level.

Ask about subscription discounts

Several clinics offer reduced rates for ongoing subscriptions vs one-off purchases. Check if your clinic offers a subscription plan and what the cancellation terms are.

Factor in the full cost

The cheapest monthly price isn't always the best value. Consider what's included — clinics offering coaching, aftercare, or unlimited follow-ups may save you money on support services you'd otherwise pay for separately.

Frequently Asked Questions

Why do prices vary between clinics?
Each clinic sets its own pricing based on their business model, level of support included, and supply costs. Some include extras like coaching, apps, or aftercare programmes in their price. Others offer a more basic service at a lower cost. All clinics listed are CQC-registered and use GPhC-regulated pharmacies.
Are there any hidden costs I should know about?
Ask your chosen clinic about: repeat consultation fees (some charge for follow-ups, others include them), delivery charges, cancellation policies, and whether there are minimum subscription periods. All clinics on SlimmingBoost include the initial consultation in their listed price.
Is there a cheaper way to get these treatments?
Wegovy is available free through NHS specialist weight management services if you meet NICE criteria (TA875), though waiting lists vary by area. For private treatment, check if clinics offer subscription discounts, introductory offers, or referral programmes. Some clinics are cheaper at lower doses during escalation.
Do prices change when I move to a higher dose?
Yes. Higher doses cost more because they contain more active ingredient. The cost increases with each dose step during escalation. Our calculator shows the exact price at each dose level so you can plan ahead.
