Harley Street Longevity Club, which brands itself as Harley Longevity Club, sits at 2 Harley Street in the heart of London's Marylebone medical district. It runs on a membership and medical concierge model rather than a walk-in menu: each member starts with an in-depth health assessment combining blood biomarker panels, body composition analysis, DNA and epigenetic testing and multi-organ imaging, from which the clinical team builds a personalised plan. Members also get access to the Harley Lounge, the clinic's private members space, and a calendar of private events.

The medical leadership is a genuine standout. Medical Director Dr Saima Ajaz is a specialist hepatologist and lifestyle medicine physician (BSc, MBBS, MPhil, PhD, Dip IBLM/BSLM, DABRM) and an Honorary Senior Clinical Lecturer at King's College London. The wider team includes two Resident Medical Officers, Professor Sunil Kumar in lifestyle medicine and anaesthesiology, and a nutrition and science communicator. The treatment range is broad for a single site, spanning EBOO, hyperbaric oxygen, a full IV drip menu including NAD+, infrared light therapy, regenerative medicine, EMFACE and EMSCULPT, and diagnostics such as DEXA, FibroScan and an oxidative stress test.

The club is operated by London Longevity Club Limited (Companies House 16144654, incorporated December 2024, formerly YOLO Clinics Ltd) and forms part of the group of businesses around Harley Street Specialist Hospital, whose CEO Warren Vaheeswaran also leads the club. The affiliated Harley Street Specialist Hospital at the same address holds a CQC rating of Good dated 8 May 2025.
