Key facts (2026): Wegovy (semaglutide) costs approximately £200–£250 per month privately in the UK for the maintenance dose. Mounjaro (tirzepatide) costs £175–£225 per month. NHS prescribing is available through specialist weight management services for those meeting strict criteria. Ozempic (also semaglutide) is licensed for diabetes only in the UK, not for weight loss, though it is sometimes prescribed off-label.
Weight loss injections — GLP-1 receptor agonists — have transformed obesity treatment globally. In the UK, demand has exploded but NHS access remains tightly rationed. Most people are accessing these medications through private online pharmacies and weight loss clinics, at significant monthly cost.
Wegovy (Semaglutide) Cost UK 2026
Wegovy is licensed in the UK for weight management in adults with a BMI of 30+ (or 27+ with at least one weight-related condition). Private monthly costs: 0.25mg starter dose: ~£130–£160/month; maintenance dose (2.4mg): ~£200–£260/month. Available from private clinics and online pharmacies including Superdrug Health, ZAVA, and Boots Online Doctor. Always use a regulated UK provider — avoid unregulated overseas suppliers.
Mounjaro (Tirzepatide) Cost UK 2026
Mounjaro was approved in the UK for weight management in 2023 and is available privately at approximately £175–£225/month at maintenance doses. Clinical trial data shows Mounjaro produces greater average weight loss than Wegovy (approximately 20–22% body weight vs 15% for Wegovy). Private availability is good through most major online pharmacies.
NHS Access — Who Qualifies?
NHS prescribing of Wegovy and Mounjaro for weight management is available through specialist NHS weight management services (Tier 3 or Tier 4) for patients meeting strict criteria: typically BMI 35+ (or 30+ with serious comorbidities), having completed a structured weight management programme, and being under specialist care. Waiting times for NHS Tier 3 services are typically 6–18 months. GP prescribing for weight loss injections on the NHS remains very limited outside specialist pathways.
Our Verdict
Weight loss injections are clinically effective — average weight loss of 15–22% of body weight in trials — but expensive at £175–£260/month privately. For those meeting NHS criteria, the specialist pathway is worth pursuing despite the wait. For private use, only purchase from regulated UK pharmacies registered with the MHRA and CQC. Never buy from unregulated online sources — counterfeit products are a genuine risk.
