Cryo Add-on. Whole-body cryotherapy as a layered membership product.
Whole-body LN2 cryotherapy at clinically meaningful spec — three-minute sessions in a chamber operating at –140°C — offered as a layered membership product. Bolt-on at £150/month for existing Standard or Plus members; standalone at £180/month for cryo-only customers. Up to three sessions per week, 156 sessions per year. Available when the cryo chamber is committed as a Phase 02 modality alongside hyperbaric oxygen.
A daily-protocol modality, sold as a layered membership rather than a tier in its own right.
Whole-body cryotherapy is a brief exposure (typically 2–3 minutes) to extreme cold (–110°C to –140°C in clinical-grade LN2 chambers). The literature is most settled on its acute effects: reductions in delayed-onset muscle soreness, improvements in subjective recovery scores, modest anti-inflammatory effects measurable in C-reactive protein and certain cytokines. The longevity-relevant evidence is more recent and more interesting — repeated exposures appear to upregulate certain heat-shock proteins, modestly improve sleep quality in some study populations, and produce reductions in markers of chronic inflammation that compound across consistent use. Cryotherapy is not a single-session intervention; the value compounds with sustained protocol.
Operationally, cryo fits the daily-protocol rhythm in a way HBOT cannot. A session is three minutes. A member can come in before work, after a gym session, or as part of a scheduled wind-down sequence in the evening. The chamber's session capacity is generous — easily 30+ sessions per day per chamber — so the bottleneck is not session availability but member count and the per-member weekly cap that protects margin against unlimited use by a small number of heavy-use members.
Clinical-grade chamber spec
Whole-body LN2 cryotherapy chamber operating at –140°C. This is the spec the destination-tier longevity literature uses, and it is materially different from electric cryo chambers (typically –80°C to –110°C) or partial-body chambers that only cool the body from the neck down. The temperature differential is what produces the physiological response; the spec matters. Refurbished clinical-grade chambers (Cryo Innovations, Mecotec, Impact Cryotherapy) sit at £25,000 to £50,000, plus install (ventilation, oxygen monitoring — LN2 displaces oxygen so safety is critical, N2 supply tank infrastructure). All-in working capex: £35,000 to £65,000.
Up to three sessions per week, member-only booking
The membership covers up to three whole-body cryotherapy sessions per week — 156 sessions per year. The cap is generous (a typical disciplined cryo user does 2–3 sessions per week; very heavy use is closer to daily, which the cap excludes) and it protects margin against unbounded use. Bookings are made through the member dashboard or at the front desk; member-only slots are reserved during peak hours so booking pressure does not build between members and drop-in customers.
Two ways to access — bolt-on or standalone
Cryo Add-on is structured as two products. The bolt-on at £150/month (£1,800/year) is the priority sell — layered onto an existing Standard or Plus membership, it deepens the relationship with members already in the clinical architecture and creates a daily-protocol cadence around the quarterly clinical reviews. The standalone option at £180/month (£2,160/year) is for cryo-only customers without a core clinical tier. The £30/month differential is small enough that the standalone is accessible but large enough that members have a structural incentive to upgrade into the full clinical proposition over time.
Drop-in single sessions for non-members
Single drop-in sessions are available at £40 per session for non-members. This is at the lower end of UK retail cryotherapy pricing (£30–60 per session typically) and is set deliberately to make the modality accessible to first-time customers who can sample before committing to a monthly membership. The drop-in market also captures hotel guests staying outside the residential programmes, occasional users, and Healthhaus members trying the chamber before deciding whether to add the membership.
Cryo is also bundled into all four residential programmes
Programme guests get cryotherapy included as part of their bundled programme fee — 1–2 sessions on a Long Weekend, up to 10–14 on a Long View. This is operationally separate from the local membership: programme cryo is part of the residential clinical sequence rather than ad-hoc booking, scheduled around the guest's other treatments. The residential allocation is what drives the per-guest cryo cost on the residential margin model (covered in detail on the Longevity page).
The Jersey resident integrating cryo into a daily recovery practice.
Cryo Add-on is the right product for a Jersey resident — typically already training seriously, already pursuing recovery as a discipline rather than an indulgence — who wants whole-body cryotherapy as a regular part of their week. The bolt-on price-point assumes the member is already inside the Long Hotel clinical architecture (Standard or Plus) and is layering cryo on top as a daily-protocol modality. The standalone product is for the Jersey resident who specifically wants the cryo without (yet) committing to the broader clinical tier.
A useful framing: cryo is the modality that members will actually use most frequently. Standard members might come in twice a year for physician contact; Cryo Add-on members might come in twice a week. The relationship the membership creates — the rhythm of being in the building, the casual encounters with the clinical and wellness teams, the proximity to the residential programmes — is operationally valuable beyond the cryo sessions themselves. Cryo Add-on is therefore both a standalone product and the highest-frequency contact channel between the proposition and its local member base.
£150 a month, with a defensible margin floor.
The pricing logic is anchored to UK comparables (cryotherapy monthly memberships typically £100–200) and to the spec premium that a clinical-grade LN2 chamber justifies over electric or partial-body alternatives. The bolt-on is set at the upper-middle of that range; the standalone carries a £30/month premium that signals the additional cost of operating outside the core clinical tier (more admin overhead, no embedded clinical context, no concierge-channel access). Drop-in single sessions are at the lower end of the comparable range to incentivise sampling.
Variable margin per session
Per-session marginal cost is approximately £5 — £4 for LN2 supply per session and £1 for maintenance and consumables allocation. The certified chamber operator's time is fixed cost (a salaried hire ramping from part-time in Year 1 to full-time from Year 3) rather than per-session variable. At £40 retail per drop-in session, the per-session contribution margin is 88%. At the modelled 100 sessions per year for a typical member (well within the 156 cap), the bolt-on at £1,800 produces approximately £1,270 contribution at 71% margin; the standalone at £2,160 produces approximately £1,600 contribution at 74% margin.
Worst-case margin at the weekly cap
If a member uses the full 156-session weekly cap each year, variable cost rises to £810 per year. Bolt-on margin in that worst case drops to 55% (£1,800 - £810 = £990 contribution); standalone drops to 60% (£2,160 - £870 = £1,290 contribution). Both are still healthy. The weekly cap is what makes the membership financeable — without it, a heavy user could consume the entire subscription in marginal cost, leaving no contribution. The cap is generous enough that disciplined members will never feel constrained; restrictive enough that the worst-case margin remains defensible.
Steady-state revenue and contribution
At the modelled mature state (Year 5): 40 bolt-on members × £1,800 = £72,000 / year, 15 standalone members × £2,160 = £32,400 / year, plus ~200 drop-in single sessions × £40 = £8,000 / year. Total cryo revenue: £112,400 / year. Variable contribution (before chamber fixed opex): approximately £64,700 / year at 58% blended margin. After the cryo allocation of chamber fixed opex (LN2 base supply, dedicated operator allocation, maintenance — roughly £24,000 / year on a 30% allocation of the £80k Year 5 total chamber opex), net cryo contribution at maturity is approximately £40,700 / year at 36% net margin.
Why this is toggleable rather than committed by default
Cryo Add-on requires the cryo chamber to be committed as a Phase 02 capex addition — £35,000 to £65,000 of working capex, plus the LN2 supply infrastructure, plus the certified-operator hire. The cornerstone Standard and Plus tiers run on existing infrastructure (clinical lead on payroll, Medilab partnership in place, DEXA available) with no additional fixed capex; Cryo Add-on does not. This is why Cryo and HBOT are presented as a toggleable Phase 02 addition on the Membership page rather than as default inclusions — they break the existing-infrastructure premise of the cornerstone tiers. The full case for committing them is on the Longevity page.
How this fits the wider proposition.
Cryo Add-on is one of two Phase 02 modalities that depend on chamber commitment. The other is HBOT, which is sold by package rather than by membership for capacity-related reasons.
Long Club Standard — the volume-tier clinical membership. Cryo Add-on bolt-on price assumes the member already has Standard or Plus.
Long Club Plus — the flagship clinical membership. Cryo Add-on bolt-on layers naturally on top.
Cryo Add-on — this product. £150/month bolt-on or £180/month standalone.
HBOT Packages — hyperbaric oxygen sold as a 60-session protocol package, 12-session block, or single session. Not a membership — chamber capacity hard-caps at roughly twelve full protocols per year.
