Our review
Welbeck is a multi-specialty private clinic campus at 1 Welbeck Street, Marylebone, operating under several linked 'ASI London' entities (holding company ASI Welbeck Holdings Limited), each separately CQC-registered and rated 'Good'. Its weight-management pathway is consultant-led: a triage call, initial clinical review, diagnostics (blood panel, abdominal/gallbladder ultrasound, and optional thyroid ultrasound or MRI), and a multidisciplinary team plan that can include GLP-1 therapy alongside dietetic and psychological support, overseen by named specialists including endocrinologist Dr Vassiliki Bravis and bariatric surgeon Professor Sanjay Purkayastha. The initial consultation and diagnostic package starts at £2,000, with ongoing costs varying by care recommended. Notably, Welbeck's public pages describe 'GLP-1 therapy' generically and never name a specific branded medication such as Wegovy or Mounjaro. No Trustpilot or Google rating data was found. Best for: patients wanting a thorough, consultant-led diagnostic workup before starting GLP-1 therapy, and able to pay a premium for it.

How it works
Consultant-led pathway: triage call to match the patient with an appropriate consultant; initial consultation with comprehensive clinical review; diagnostics (blood panel, abdominal/gallbladder ultrasound, optional thyroid ultrasound and MRI); multidisciplinary team review; personalised treatment plan that can include GLP-1 therapy alongside psychological support and specialist dietetic input; ongoing consultant-led monitoring covering initiation, optimisation, or discontinuation of GLP-1 medication. Named consultants involved in weight management include Dr Vassiliki Bravis (Endocrinologist), Professor Sanjay Purkayastha (Upper GI/Bariatric Surgeon), and Dr Nowlan Selvapatt (Gastroenterologist).
Things to know
- The weight-management page advertises 'GLP-1 therapy'/'GLP-1 medication' generically but does not name any specific branded drug (no mention of Wegovy, Ozempic, Mounjaro, Saxenda, semaglutide, or tirzepatide) anywhere in the publicly fetchable content as of 2 Aug 2026 — a transparency gap versus competitors that do name their medications and doses.
