Fifty-something years ago, Tramp on Jermyn Street became the place where royals, rockstars and various scandal-magnets went to misbehave after dark. Now the Mayfair institution has branched out in a very different direction: Tramp Health, a private wellness club that opened in 2026 inside the former American Embassy building, now the Chancery Rosewood hotel, a short stroll from the original club.

Founder Luca Maggiora, who launched the venture with doctor Mark Mikhail, has essentially bottled the Tramp formula — privacy, membership, a certain old-school exclusivity — and poured it into spa treatments, fitness studios and a café. He personally interviews every applicant and prioritises keeping numbers low, so the space never feels packed. There's no app queue for a treadmill here; members move between Technogym and Alo-branded training rooms, HIIT and Reformer studios without waiting.

The facilities run deep. Down in the cave-like underground, designed by Chelsea studio Tomèf, you'll find a cedar sauna, two cold plunges set at different temperatures (a thoughtful touch, given research suggesting women benefit from milder cold exposure), therapy rooms, an IV drip room and a hyperbaric oxygen chamber aimed squarely at jet-lagged frequent flyers. The treatment menu is equally ambitious: an EmSella chair that claims to deliver the equivalent of 12,000 pelvic floor kegels in fifteen minutes, a full-body red light therapy bed, lymphatic gut massages, crystal sound bowl classes, and an Aura 3D skin scan that maps pores, redness and even your skin's biological age before a facialist builds a personalised facial — complete with fruit-enzyme peels and stern aftercare instructions.

Fuel comes courtesy of the Tramp Café, an indoor-outdoor terrace serving cold-pressed ginger shots (mercifully apple-juice-free, per the reviewer), smoothies, grilled sea bass and, in a nod to the club's less ascetic roots, truffle tagliolini. Mikhail is also on hand for blood tests and prescribed health plans, making this as much a medical-wellness hybrid as a day spa.

Who's it for? Wealthy Londoners who want balance without giving up the good stuff — wine, pasta, dancing — plus travellers passing through Mayfair who'd pay for serious recovery facilities after a long-haul flight. It's a distinctly adult, distinctly discreet kind of place, and a sign of where members' clubs are heading: less bottle service, more red light beds.
