Britain's longevity clubs start at £10,000 a year. Here's what members actually get.

The British version of the longevity boom is quieter than the American one, and usually attached to a hotel. Where New York does spectacle, London does discretion: members’ clubs beneath five-star addresses, where the spa has quietly become a clinic and the price of entry buys a blood test as readily as a massage.

Surrenne: £15,000 to begin, and it sold out

The flagship is Surrenne, which opened in April 2024 beneath The Emory hotel in Belgravia. Individual membership is 10,000 pounds a year, a couple pay 14,000, and there is a 5,000 pound joining fee on top. It was capped at 100 members and, by reports, sold out. Spread over four floors, it pairs the expected luxury, a 22 metre pool, London’s first Tracy Anderson studio and a snow room, with a genuine longevity clinic run in partnership with a medical group, 3 Peaks Health, under a named medical director. The testing menu covers cardiovascular health, hormones, metabolism and, tellingly, methylation testing, the epigenetic biological age measure. Its scientific advisory board lists the neuroscientist Andrew Huberman and the longevity researcher David Sinclair.

Hooke: the diagnostic deep end

If Surrenne is a club with a clinic inside, Hooke is closer to a clinic that feels like a club. Its memberships have been reported at 8,000 to 28,500 pounds a year, and the top tier leans hard into testing: full-body MRI, whole-genome sequencing, even a colonoscopy, distilled into a single BioScore. It is the clearest example of a British trend to sell healthy people the kind of scanning that used to be reserved for patients with symptoms.

The wider London scene

Above these sit clubs that, according to the South China Morning Post, can exceed 50,000 pounds a year. Below them, the entry point keeps dropping: Neko Health, the body-scan company, offers a full-body scan in London for 299 pounds, no membership required. The direction of travel is clear. Diagnostics that once needed a referral are becoming a lifestyle purchase.

What the science says back

This is where a British reserve is worth keeping. Two of the signature offerings deserve scrutiny before you sign. The methylation, or biological age, tests that Surrenne and others feature are, in the words of the researchers who build them, not designed for individuals and can swing with your diet or the time of day. And the full-body MRI scans at the heart of the priciest packages are not recommended for healthy people by the main radiology bodies, precisely because they raise more false alarms than real ones. Hyperbaric oxygen and IV drips, both fixtures of these menus, are useful for specific medical conditions but unproven for anti-aging.

None of which means the clubs are worthless. The coaching, the pool, the structure and the company are real, and for someone who uses them, valuable. It is the six-figure diagnostic layer where the price outruns the proof. The measures that genuinely track how long you will live, your fitness and your strength, cost almost nothing.
