What you'll typically pay in London: £45–70 for a single whole-body cryo session, £350–550 for 10-packs. The Harley Street tier sits at the top; central London boutique studios at the mid-tier; the few outer-zone (Hammersmith, Islington) options run lower. Equipment is mostly electric whole-body units from CryoAction, JUKA and Mecotec — nitrogen-vapour chambers are less common in London than in continental Europe.
London's cryotherapy scene has had notable Premier League and rugby-union uptake — Tottenham Hotspur, Chelsea FC, England Rugby and several Olympic teams have used central-London chambers. Some clinics carry that pedigree explicitly through trainer relationships; others are simply consumer-facing studios. Worth checking when choosing based on operational rigour.
