Viavi

Viavi is one of London's longest-running longevity clinics, operating from Devonshire Place near Harley Street since 2015. The proprietary Pyramid of Healthy Longevity framework combines 22,000-gene analysis with blood panels, epigenetics, microbiome assessment, and lifestyle evaluation across a comprehensive two-day assessment. The clinic has earned genuine endorsements from high-profile clients and coverage in major international publications including Bloomberg, British Vogue, and the Australian Financial Review, reflecting the caliber of its client base. The blood plasma purification service adds a therapeutic dimension that is rare among diagnostics-focused longevity competitors, and the brain health evaluation has generated notable clinical insights relevant to high-performing professionals. Ten years of operational history provides a depth of experience that few longevity clinics in London can match. The pricing is firmly premium, with the full two-day evaluation running approximately GBP 42,000, which reflects the depth of analysis and therapeutic components but also limits accessibility. The diagnostic suite does not currently include full-body MRI, and pricing transparency on the website could be improved to help prospective patients plan. For high-net-worth individuals seeking London's most established longevity practice with genuine genetic depth and therapeutic capabilities beyond pure diagnostics, Viavi delivers a comprehensive and well-regarded experience.
